Hello everybody, welcome back to Reading for Vocabulary.
2
I'm Brian Stewart.
3
We're on lesson three right now.
4
We're talking about pollution and of course our unit is about environment.
5
So pollution is very important when we talk about the environment.
6
In this lesson we will focus on pollution is bad for the environment.
7
It's bad because it affects our health.
8
So the subject that we're going to be talking about in this lesson is about health
9
and not only our health but the health of our planet, the Earth.
10
So let's take a look.
11
Let's look at the ideas here first, kinds of pollution.
12
In this unit we're going to be talking about two kinds of pollution.
13
There are many kinds of pollution, but we'll look at two kinds here.
14
The first one, what kind of pollution do you think this is?
15
This is a factory, right?
16
And it's putting pollution in the air.
17
So this is air pollution.
18
Air pollution, when something puts bad gases or gases that are not good for you in the air.
19
Factories, cars, people smoking, right?
20
This is all types of air pollution.
21
Another type of air pollution we'll talk about, what is this?
22
This, of course, is water.
23
And blech, that's horrible, right?
24
Look at that black stuff coming out of this pipe into the water.
25
That, of course, is water pollution.
26
So, water pollution is very bad it hurts you know we have to drink clean water
27
when we take a shower we want clean water we want our water to be clean
28
so we have to watch out for these two types of pollution air pollution
29
and water pollution we'll look at those in this unit
30
but first let's build our vocabulary right let's look at some
31
vocabulary words to help us talk about these issues the first word we're going to talk about,
32
we've already seen it, I just talked about it, the bad things in our air and water.
33
Right?
34
Air, beep, water, beep.
35
Do you remember?
36
Just a couple seconds ago we were talking about pollution.
37
Pollution.
38
Now this is a long word, right?
39
It has three sounds.
40
Pollution.
41
Put them together.
42
Pollution.
43
Pollution.
44
Pollution.
45
So, you guys, pollution.
46
These are the bad things in our air and water.
47
Pollution is what we have to watch out for.
48
Okay, our second word, we have two apples here, right?
49
This apple is very nice.
50
It looks fresh.
51
It looks good to eat.
52
This apple is rotten.
53
Rotten, right?
54
This apple is rotten.
55
Whoops.
56
Oh, wow, look at that.
57
My pen advanced the word.
58
That's okay.
59
So this apple is rotten.
60
If you eat it, it's harmful.
61
It causes harm, right?
62
So, time, air, causes harm to an apple or other fruit because they become rotten.
63
It's harmful.
64
Now, there's two sounds here.
65
Harm-ful.
66
Harmful.
67
Put them together.
68
Harmful.
69
Okay?
70
So, when it causes harm, it is harmful.
71
Pollution is harmful.
72
We'll talk about that later.
73
Okay.
74
Next one.
75
This is interesting.
76
I have to think a little bit what's going on here.
77
To stop, to stop from happening, what's he doing?
78
He's stopping the water from falling in the sink, right?
79
He's catching it in his hands.
80
So to stop from happening is to prevent.
81
If you prevent something, pre-vent, two sounds, prevent, prevent.
82
it together quickly?
83
Prevent.
84
Okay, so prevent, to stop something from happening.
85
Okay, number four.
86
We saw this before in the very beginning of our lesson when we talked about air pollution, right?
87
But what type of building, what type of place is this?
88
It's a place where things are made by machines." So you have many machines and things are made by machines like cars,
89
refrigerators, television sets.
90
Things are made by machines.
91
It's a big building, we call it a factory.
92
A factory is a place where things are made by machines.
93
Almost everything these days is made in factories.
94
Next one, look at him.
95
He was having fun, right?
96
He was digging in the dirt.
97
Hook, hook, he's got lots of dirt on his hands.
98
Not clean.
99
His hands are not clean.
100
He should not go home and eat.
101
He's got to wash his hands first because his hands are dirty.
102
Mom will say, your hands are dirty.
103
Wash your hands, right?
104
Hopefully he doesn't go like this.
105
Then his face is dirty, right?
106
So be careful when you go play outside, your hands get dirty, your clothes get dirty, maybe your face gets dirty, your hair gets dirty.
107
What were you doing?
108
Okay, but it gets dirty when you play in the earth or in the dirt.
109
Okay, next one.
110
Where do we all live?
111
Do you know this picture?
112
Have you seen this picture before?
113
Or you've probably never actually seen this, you've just seen this picture, right?
114
Because it would be very difficult to go outside.
115
Only astronauts see this in real life.
116
It's the planet we live on.
117
What is this planet called?
118
We all live on this planet.
119
It's called Earth.
120
It's Earth.
121
So we live on Earth.
122
Okay, next one.
123
Ah, looks refreshing, doesn't it?
124
It's hot and you should drink lots of this on hot days.
125
It's a clear liquid with no taste.
126
It doesn't taste like anything, but it's very refreshing, isn't it, on a hot day.
127
It's, of course, water.
128
Water is necessary for us.
129
If we drink a lot of water, we are healthy.
130
So water is important to us.
131
And the water has to be clean, not dirty.
132
Okay, number eight, to take in, to take in and give out air.
133
Well, think about that.
134
What am I doing?
135
I am breathing, to breathe.
136
This is maybe a little difficult to pronounce because you have these consonant blends.
137
You have these sounds here.
138
First is B-R, brr, brr and the next one th
139
so breathe breathe calm down relax it's okay it's not hard breathe breathe
140
breathe okay when you make the th sound at the end breathe your tongue is between your teeth breathe
141
and it's vibrating, right?
142
You have a little vibration.
143
Breathe, breathe.
144
Okay, you can feel the vibration.
145
Breathe, and then you can say it.
146
Don't say breath.
147
That's something else.
148
That's the noun, right?
149
Breath is the noun.
150
Breath.
151
No vibration.
152
Breath.
153
That's the noun.
154
Take a breath.
155
That's a noun.
156
But verb, this is the verb the verb, that's the action.
157
Breathe, breathe.
158
So, don't get confused, right?
159
Take a breath.
160
Breathe slowly.
161
Okay, so that's the difference.
162
Okay, next word.
163
Number nine, to put different things together.
164
You have one thing here, you have another thing here, you're going to put them together.
165
What are you doing?
166
That's very easy.
167
Mix.
168
You will mix the two things together.
169
Sometimes we mix a solid with a liquid, but you can also mix two liquids, two solids.
170
You can mix gas.
171
There's lots of things you can mix together.
172
So mix to put two different, well, different things, two, three, four, you put many things together,
173
you are mixing to mix.
174
Okay.
175
Number 10.
176
Uh-oh, looks like trouble, right?
177
Here's a helicopter, right?
178
This of course is a helicopter, and it looks like it's doing something not good, right?
179
Dirty air made when something is burning.
180
So, at first when I saw this picture I thought, uh oh, the helicopter is in trouble.
181
But no, it's not in trouble, it's the engine.
182
It's the engine making the smoke.
183
Cars do this too.
184
What do we call this?
185
What do we call this smoke?
186
That's kind of a himdoro word.
187
That smoke is called exhaust.
188
But we can also call it smoke.
189
I just said smoke.
190
Smoke from the engine is called exhaust.
191
And that's because what's burning?
192
Well, the gasoline is burning inside the engine and it's giving off smoke.
193
But if you have a fire, if you go camping in the woods and you make a fire, that's smoke that comes off the fire.
194
Not exhaust.
195
Exhaust is from an engine.
196
Exhaust comes from an engine.
197
Smoke comes from any fire, right?
198
Also we can call this smoke too.
199
is a type of smoke.
200
Okay.
201
Eleven, is it smoke?
202
No, it's tiny pieces of dirt.
203
Nothing's burning, right?
204
This person just took some dirt, picked up some dirt, rubbed it, clapped it on his hands, right?
205
And why did they do that?
206
To make their hands like more, the things will stick.
207
Like if he's going to grab a rope and pull it, he wants his dirt to help him grip that rope.
208
But the little tiny pieces of dirt.
209
What do we call that?
210
We call it dust.
211
Maybe a little bit difficult to pronounce.
212
We have D, D, D and ST, ST. Dust.
213
Don't say DST.
214
No, don't say don't do that.
215
It's one sound.
216
Dust.
217
Be careful with the ending sound.
218
Don't put U at the end.
219
Don't do that.
220
It's just dust.
221
Tiny pieces of dirt in the air.
222
Number 12, having an illness.
223
Oh, poor guy.
224
He doesn't look good.
225

but this is nature this is what happens in nature are animals have to eat right
258
so these two looks like cheetahs They caught a deer or a gazelle and they cause to die.
259
They catch it and they kill it.
260
Kill it.
261
They cause it to die.
262
So when a big cat, a hunter, right, catches another animal and kills it, of course it causes the animal to die, to kill.
263
It happens in nature.
264
This is the natural world.
265
Okay.
266
Let's review our words that we've learned.
267
Let's see how well we remember.
268
Now we've got, wow, we've got a lot of words.
269
We have eight words here.
270
These are the words we're going to use.
271
It says complete each sentence with a word from the box.
272
So we have eight sentences.
273
We have to complete each sentence with one of these words.
274
What are the words?
275
Let's review.
276
Pollution.
277
Pollution.
278
Pollution.
279
Next here.
280
Prevent.
281
Prevent.
282
Next one, breathe.
283
Dirty.
284
Then next one is harmful.
285
Next one is factories.
286
Next one, water. And next one, earth.
287
That's where we all live.
288
How do we complete these sentences with these words?
289
Number one, fill the air with dust and smoke.
290
So what fills the air with dust and smoke?
291
What does that?
292
What of these things fills the air with dust and smoke?
293
Think of a place where machines make things, right?
294
Factories is a place where machines make things and they unfortunately,
295
they also fill the air with dust and smoke when the machines are working.
296
So they fill the air with dust and smoke.
297
Number two, it is hard to beep if the air is not clean.
298
So imagine the air is not clean.
299
Maybe somebody's smoking nearby.
300
You're going, right?
301
It's hard.
302
It's difficult to do what?
303
What is that action?
304
Remember that word?
305
breathe.
306
Breathe.
307
Remember, this is a verb.
308
The noun is breath, but we need a verb.
309
It is hard to breathe if the air is not clean, if the air is dirty, somebody's smoking near you, or there's a lot of cars,
310
you're near a highway, there's a lot of exhaust.
311
It's hard to breathe.
312
Okay, let's move on to number three.
313
Number three is let's keep the beep green and clean.
314
Green and clean?
315
What are we talking about?
316
Well, out of all these places, what do we want to keep green and clean?
317
Out of all these things, not places, all these things.
318
Where do we all live?
319
Where do we all live?
320
We all live on the earth.
321
Let's keep the earth green and clean.
322
Green?
323
What does that mean?
324
Well, think about it.
325
We want our earth to have lots of trees and lots of plants, right?
326
Those are green.
327
If we keep our water clean, if we don't pollute our water, there will be many trees and lots of grass, lots of plants.
328
So it'll be green, green and clean.
329
Let's keep the earth green and clean.
330
Number four, factories and cars make what?
331
We've talked about this before.
332
We've talked about it actually on the previous slide.
333
Number one, we've talked about factories, right?
334
But also cars, what do they make?
335
They make the air and the water dirty.
336
So what do they make?
337
What makes things dirty?
338
Well, pollution makes things dirty.
339
So factories and cars make pollution.
340
It's something that they do.
341
It's not something they're designed to do.
342
It's just something they do as like a side effect of using those things.
343
Factories aren't built to make pollution, it's just something that happens with that other activity that they're doing.
344
Same thing with cars.
345
We like cars, we like to drive, but unfortunately, they also cause pollution.
346
Okay, let's move on to number five.
347
We need clean beep to drink.
348
That gives us our answer right there, because what do we drink?
349
What do we drink?
350
Of these things, what is it that we drink?
351
And we talked about this before.
352
It should be clean when we drink it.
353
Of course, we're talking about water.
354
We need clean water to drink.
355
Our water that we drink, ah, it's very refreshing, but it should be clean.
356
If it's dirty water, that's harmful.
357
So it should be clean.
358
Six, Jim.
359
He's my friend, right?
360
Jim.
361
Jim doesn't drive.
362
He wants to beep, air pollution.
363
So what does he want to do?
364
Air pollution is bad.
365
He wants to stop it.
366
He wants to stop it from happening.
367
What word did we learn that means to stop from happening?
368
Which of these words means to stop from happening or to stop happening?
369
That of course is to prevent.
370
He wants to prevent air pollution.
371
So that's one way to help prevent air pollution.
372
Don't drive.
373
You can walk or you can ride a bicycle.
374
That's how you can prevent air pollution.
375
Number seven, burning things.
376
If you burn something, it could be gas, it could be wood, it could be paper.
377
Those things make our air what?
378
Because remember the smoke is coming off and that smoke makes the air.
379
What does it make the air?
380
What of these words, what describes how the air is when there's a lot of smoke or pollution in the air.
381
The air is then dirty.
382
The air is dirty because we're burning things.
383
Burning things makes smoke, it makes pollution, it makes the air dirty.
384
8. Pollution is what to plants and animals?
385
Pollution is bad, right?
386
What's another word for bad here?
387
It causes harm.
388
It's bad because it causes damage or it causes harm to something.
389
Of course, we're looking for harmful, right?
390
It causes harm, it is harmful to plants and animals.
391
Of course, pollution is bad to plants and animals.
392
We are animals, so it's bad for humans, it's bad for all other animals, it's bad for plants.
393
Pollution is harmful to plants and animals.
394
Okay, that wraps up our vocabulary review.
395
We have a lot of good words now.
396
Let's use those words after a short break and take a look at the reading section.
397
Let's take a short break.
398
Hello, everybody.
399
Welcome back to the reading passage.
400
Now, we're going to go over the reading here.
401
Of course, our subject is pollution.
402
Are you ready?
403
Let's begin together.
404
The reading passage starts with a question.
405
Do you know what pollution is?
406
Do you know what pollution is?
407
You should know by now, right?
408
But then it answers, pollution makes the earth dirty.
409
So that's the answer to the question.
410
It's something that makes the earth dirty.
411
What is pollution?
412
It makes the earth dirty.
413
It, now the next sentence starts with if, it we're talking about pollution.
414
Pollution puts bad things into our air and water.
415
So that also answers the question, what is pollution?
416
Pollution makes our earth dirty and it puts bad things in our air and water.
417
Harmful things, not good for us.
418
Now here we have many things that we do make our earth dirty.
419
Separate the sentence.
420
Many things that we do. that we do.
421
For example, we make things, we drive cars, we do a lot of things.
422
Those things that we do, they in turn make our earth dirty.
423
So we kind of have to separate this here.
424
Many things that we do, many of the things that we do, those things make our earth dirty.
425
So let's talk about what they are and how to prevent pollution.
426
When they say let's talk about what they are, we're talking about the things that we do.
427
So we're going to see more examples of things that we do.
428
Let's talk about what those things are and how we can prevent, stop pollution.
429
So we're going to look at two things, right?
430
of the things that we do that makes pollution and how we can stop pollution from happening.
431
That's what the next part is going to be about.
432
Air pollution is when harmful things mix with the air.
433
Air pollution, we're talking about air pollution first, is when harmful things mix with the air.
434
Remember we said mix means you take many different things and you put them together.
435
If you put smoke together with the air, that makes air pollution.
436
Dust and smoke from cars and factories are pollution.
437
So these are the things we do.
438
We drive cars and we make things in factories.
439
That's something we do.
440
That's something we do.
441
When we do that, we make dust and smoke.
442
That makes pollution.
443
That makes our environment dirty.
444
So, air pollution is when harmful things mix with the air, harmful things like dust and smoke from cars and factories are pollution, are air pollution.
445
So, that kind of sums up those two sentences.
446
Air pollution, they.
447
They here refers to dust and smoke.
448
Dust and smoke, they make the air harmful to breathe.
449
So, if there's a lot of dust and smoke in the air, those things make the air harmful to breathe.
450
It's hard to breathe, actually, right?
451
If there's a lot of dust in the air, we cough and we sneeze.
452
It's harmful to breathe.
453
Too much pollution makes living things sick, right?
454
It makes us sick if there's too much dust or smoke in the air and especially too much pollution,
455
we can become sick.
456
And many other living things can become sick too and die.
457
Okay, let's move on.
458
Clean air is good for plants too, right?
459
Not just for animals or creatures, but also for plants.
460
Of course, plants need clean air.
461
It, what's it?
462
Clean air.
463
It refers back to clean air.
464
Clean air helps them.
465
What's them?
466
Plants.
467
Okay.
468
So them is plants.
469
Clean air helps plants grow and stay green.
470
Of course, plants need clean air to grow and to stay green.
471
If they don't get clean air, they die and they turn brown.
472
Right.
473
So they want to stay green, stay healthy.
474
So, the question is, how can we stop air pollution?
475
How can we stop air pollution?
476
What can we do to help prevent air pollution?
477
We can walk and ride bicycles more.
478
What does that mean, if we walk and ride bicycles?
479
Because it means less driving.
480
If we walk or we ride a bicycle, we're not in a car, we're not in a taxi, we're not in a bus.
481
Those things cause air pollution.
482
But walking doesn't cause pollution, riding a bike doesn't cause pollution, so that's how we can stop air pollution,
483
walking and riding bicycles more.
484
Less driving.
485
If we do that, we don't drive as much or we don't use the bus, maybe less buses.
486
less pollution.
487
Less driving means less pollution.
488
That's one way we can do something to help stop air pollution.
489
We talked about air pollution, that was one of the types of pollution.
490
Now let's talk about water pollution.
491
Water is something we use every day.
492
Of course you should drink lots of water every day.
493
I I hope you take a shower every day.
494
I should take a shower.
495
No, I'm just kidding.
496
Okay, but sure, we take a shower every day, or we go to the sauna.
497
We need clean water for these things.
498
You don't want to take a bath in dirty water.
499
That's yuck, yuck, right?
500
Okay, okay.
501
So water is something we use every day.
502
We need it to cook, we clean, and to live, right?
503
Our mother uses clean water to cook.
504
I said we take a shower, we go to the sauna, we clean things with clean water, and we live, we need water to drink.
505
But sometimes harmful things mix with our water, right?
506
Like this, blech, terrible, horrible.
507
This dirty, disgusting water is mixing with the clean water in the river.
508
It's making the whole river dirty, right?
509
Water pollution is when the water is not clean.
510
So this water is not clean.
511
So this is water pollution.
512
That's when harmful things mix with our water.
513
We don't want that.
514
People put trash and other bad things in the ocean. So that's true.
515
If people throw out their trash, sometimes people will take that trash and throw it in the ocean.
516
That's horrible, that's terrible.
517
I read on the internet that there is plastic bottles and plastic wrappers in the Pacific Ocean.
518
It makes the size of a state of Texas in America.
519
It's huge in the Pacific Ocean.
520
All that trash is in the ocean.
521
That's terrible.
522
It makes the water dirty.
523
Other bad things, other bad things like chemicals and things like that are making the ocean dirty.
524
Dirty water can kill plants.
525
The plants along this river might die because those plants need fresh, clean water to grow.
526
Not just plants, it makes animals sick if they drink it or swim in it.
527
Of course, it is dirty water.
528
Dirty water makes animals sick if they drink dirty water or swim in dirty water have many its.
529
These its all refer back to dirty water.
530
Dirty water can kill plants, it makes animals sick, if they drink it or they swim in it.
531
That's all dirty water.
532
That's what dirty water does.
533
However, we can help stop water pollution.
534
Yes, we can do something to help stop water pollution.
535
What can we do?
536
Well, let's pick up the trash and keep our water clean.
537
So if you see trash on the ground, instead of letting it, you know, roll down and get into a river or a stream and wash away, pick it up, put it in the right place.
538
Also, keep the water clean.
539
Keep the water clean.
540
Don't put chemicals down your sink, right?
541
Be careful what you do with the water in your house.
542
Okay, so those are things we can do to help stop water pollution.
543
Okay, pollution is bad for the earth.
544
Of course, we know that.
545
Let's make sure.
546
Make sure means let's check.
547
Let's be careful, right?
548
Let's make sure our air and water are clean.
549
We have to make sure that our air and water are clean.
550
If we do that, if we do that, if we make sure our air and water are clean,
551
if we do that, the earth will be beautiful forever.
552
So the earth is a beautiful place, isn't it?
553
We want to keep it beautiful.
554
So we need to make sure air and water is clean.
555
Okay, that wraps up the reading passage.
556
Let's talk about our reading comprehension questions.
557
Okay, question number one, what are we talking about?
558
What is this story, this reading passage about?
559
What's it about?
560
What's the big subject.
561
Number one, it's about flowers.
562
I don't remember anything about flowers, do you?
563
I don't remember anything we were talking about flowers.
564
We didn't say flowers at all.
565
The A is not right.
566
B, fish.
567
Did we talk about fish?
568
Do you remember fish?
569
I don't remember fish.
570
There's no fish.
571
Okay, we didn't talk about fish.
572
Factories.
573
Okay, we did talk about factories, but that was just a small detail in the reading passage, right?
574
That was just a small part of the story, not the whole picture.
575
D, pollution, yeah, pollution.
576
That's what we were talking about, right?
577
D is the right answer.
578
This story is about pollution because we talked about what causes pollution.
579
We talked about how we can stop pollution.
580
We talked about air pollution.
581
We talked about water pollution.
582
So we talked all about pollution.
583
So pollution is the correct answer.
584
Number two, pollution, beep, we need a long part of the sentence, right?
585
We only have the subject.
586
What's the rest of the sentence?
587
What's true?
588
A, pollution makes the earth dirty.
589
Is that true?
590
You bet.
591
Pollution makes the earth dirty.
592
That's our answer.
593
So pollution makes the earth dirty.
594
Let's just look at B, C, and D for practice.
595
Pollution is good for plants and animals.
596
What?
597
We said pollution can kill plants and animals.
598
It's not good for plants and animals.
599
So that's not right.
600
C. Pollution is made by trees.
601
No. Pollution is made by factories, by cars, by trash, by things that we do.
602
Not by trees.
603
Trees don't make pollution.
604
If that were true, the earth would be really, really dirty.
605
All the trees would die.
606
So that's kind of a crazy answer.
607
D. Pollution helps plants grow.
608
Pollution is good for plants.
609
No, we said pollution is bad for plants.
610
So that's not right.
611
So again, our only correct answer is A.
612
Pollution makes the earth dirty.
613
Okay, let's move on.
614
Number three.
615
Now we're missing the subject, right?
616
Number two, we have the subject, we need the rest of the sentence.
617
Now we have the opposite situation.
618
We're missing the subject, we have the rest of the sentence.
619
So we need the subject.
620
The subject helps plants grow and stay green.
621
So what helps plants grow and stay green?
622
We know it's not pollution, right?
623
We saw that number two, it's not pollution.
624
We can see that right away.
625
What about A?
626
Driving cars helps plants grow and stay green.
627
Driving cars makes pollution and pollution does not help plants grow and stay green.
628
So A is wrong too.
629
What about C?
630
Clean air.
631
Clean air helps plants grow and stay green.
632
Yeah, sure.
633
We talked about that.
634
Clean air is what helps plants grow and stay green.
635
Not only clean air, but also clean water.
636
So D where it says dirty water, no, not dirty water, clean water.
637
Okay.
638
So clean air helps plants grow and stay green.
639
If it was clean water, that would also be true, but D is dirty water, so that's not right.
640
Okay, number four.
641
Dirty water, we have the subject, what's the rest of the sentence?
642
Dirty water does what?
643
A, is good for lemonade.
644
What?
645
Where did that come from, right?
646
Okay, but that's kind of funny.
647
But if you think about it, if you make lemonade, you're mixing water, lemon juice, sugar and ice, right?
648
That's a really good drink.
649
Should you use dirty water?
650
It's going to taste horrible, right?
651
We don't want dirty water.
652
That's not good for lemonade.
653
Clean water is good for lemonade.
654
Okay, dirty water helps plants grow and stay green.
655
Nope, we just saw that.
656
That's not the right answer, so let's get rid of that.
657
C, dirty water makes animals sick.
658
Uh-huh, we saw that or we read that in the reading passage.
659
Dirty water can make animals sick, can also make plants die.
660
So, C is our right answer.
661
Dirty water makes animals sick, like us too.
662
So, let's not put dirty water in our lemonade, we'll get sick, right?
663
So, dirty water makes animals sick.
664
So, looking at D, D, you know, dirty water is not harmful.
665
No, we saw that before.
666
Dirty water is harmful.
667
Dirty water is harmful.
668
So we have to change D.
669
D is not correct.
670
So our right answer is dirty water makes animals sick.
671
That's number C.
672
C is the correct answer.
673
Okay, let's review what we've learned in this lesson, especially from the reading passage.
674
We have two questions here.
675
One, how can we stop air pollution?
676
How can we prevent air pollution?
677
Do you remember some of the things we talked about?
678
What causes air pollution?
679
driving cars, vehicles like buses, taxis.
680
So what can we do?
681
Well, let's see if Dr. Pollution can help us.
682
Okay, let's see.
683
What?
684
Who is that guy?
685
That's not Dr. Pollution.
686
I don't know who that guy is.
687
Okay, anyway.
688
We can walk and ride bicycles more.
689
That's how we can stop air pollution.
690
Okay?
691
We can stop air pollution by walking, walking and riding bicycles because we don't use cars or taxis or buses.
692
Thank you.
693
I don't know who that guy is.
694
He's not very handsome, is he?
695
Okay, next one.
696
How can we stop water pollution?
697
How can we stop water pollution?
698
Now I'm a bit scared.
699
I don't know who's going to come up.
700
But think about it.
701
How can we stop water pollution?
702
What can we do?
703
In the reading passage we talked about you know, trash and making the water dirty, that causes water pollution.
704
So, are you ready?
705
You want to see who comes up?
706
Oh, no!
707
It's the same guy!
708
Oh, my gosh.
709
Okay.
710
Okay, let's pick up trash and keep our water clean.
711
That's what we need to do to stop water pollution.
712
Okay, and this guy is telling us that.
713
Who is that guy?
714
Do you know?
715
Anyway, okay, so we have two questions here.
716
How can we stop air pollution?
717
We can walk, ride bicycles.
718
How can we stop water pollution?
719
We can pick up trash, keep our water clean.
720
Okay, that was our lesson on pollution.
721
I hope you've learned a lot of good words and that you enjoyed the reading passage,
722
that you picked up some interesting ideas and some good vocabulary from the reading passage.
723
We'll see you again next time, everybody.
724
Take care.

この動画は誰に向けて作られたのですか？
この動画は「環境」をテーマにした英語学習コンテンツで、Bレベルの学習者を対象としています。特に単語力を増やしながら読解力を養いたい人、また日常会話やIELTS スピーキング対策で環境関連のトピックを使いこなしたい人に最適です。工場の排気や水質汚染など身近な例を使って説明しているので、実生活での応用もしやすいです。
覚えておきたい単語と表現
動画で使われている注目すべき単語とその意味を紹介します。
- Pollution：空気や水に混入する有害な物質のこと。「工場からの排気はair pollution（大気汚染）だ」のように使います。
- Fresh：新鮮な、鮮やかな。「This apple looks fresh（このリンゴは新鮮そうだ）」のように、食べ物や空気の質を表すのに使います。
発音を上達させるコツ
動画のスピーカーは明瞭なアメリカ英語を話しています。特に「pollution」の発音に注目しましょう。この単語は3つの音節に分かれ、「pəˈluːʃn」と発音します。shadow speech（シャドーイング）の練習に最適です。スピーカーの発音を聞きながら、すぐに繰り返して口の動きとリズムを覚えましょう。また、「air pollution」「water pollution」のようなコロケーションも、自然な発音で言えるように練習します。これは英語の発音を良くするだけでなく、IELTS スピーキング対策にも役立ちます。
動画で英語学習を効果的に行う方法
動画を見ながら学ぶ場合は、shadowspeaksのような方法を使いましょう。スピーカーの発言を1~2秒遅れで追って話すことで、リスニングとスピーキングのスキルを同時に鍛えることができます。また、単語の意味を理解した後は、自分の言葉で「Pollution is bad for the environment（汚染は環境に悪い）」のような文を作ってみましょう。これで単語の定着度が上がり、自然な会話ができるようになります。
この動画の文法
話し手がよく使っている文型を、動画の実際の表現とともに紹介します。
| 文型 | 動画での表現 |
|---|---|
| 条件文 if + 節, will/would + 動詞 — 条件とその結果 | if we do that, the earth will be · If that were true, the earth would be · If it was clean water, that would also |
| 受動態 be + 過去分詞 — 誰がするかより、何が起きるかに焦点を当てる | are made · is made · is called |
| 現在完了形 have/has + 過去分詞 — 過去の出来事が今も関係している | we've already seen · Have you seen · you've just seen |
| 過去進行形 was/were + -ing — 過去のある時点で進行中だった動作 | were talking · was having · was digging |
シャドーイングとは？英語上達に効果的な理由
シャドーイング（Shadowing）は、もともとプロの通訳者養成プログラムで開発された言語学習法で、多言語習得者として知られるDr. Alexander Arguelles によって広く普及されました。方法はシンプルですが非常に効果的：ネイティブスピーカーの英語を聞きながら、1〜2秒の遅延で声に出してすぐに繰り返す——まるで「影（shadow）」のように話者を追いかけます。文法ドリルや受動的なリスニングと異なり、シャドーイングは脳と口の筋肉が同時にリアルタイムで英語を処理・再現することを強制します。研究により、発音精度、抑揚、リズム、連音、リスニング力、そして会話の流暢さが大幅に向上することが確認されています。IELTSスピーキング対策や自然な英語コミュニケーションを目指す方に特におすすめです。
