Unit 9, Track 20 Hello, Joe.
2
Come in and take a seat.
3
I wanted to talk to you about your essay on weather control.
4
Right.
5
What did you think?
6
Well, let's start by looking at your introduction.
7
You say that global warming is causing extreme weather conditions around the world.
8
That's right, isn't it?
9
Well, you need to be careful here.
10
Yes, there is a lot of evidence that this is the case, but the issue is still controversial.
11
You need to specify that many experts believe this is the case, rather than saying this is how it is.
12
OK.
13
Then you look at the issues surrounding extreme weather, erm, and how it has a negative effect in some countries.
14
I was worried that that section was a bit disorganized.
15
No, not at all.
16
It's very good.
17
But I was slightly surprised when, in the same paragraph, you mentioned an advantage of extreme weather.
18
Not the right place for it?
19
Not really, no. In fact, I would question the need to put it there at all.
20
At one point you're talking about droughts,
21
hurricanes, floods, etc. And then suddenly you're talking about people being able to sunbathe on the beach in January.
22
Ah, I see what you mean.
23
I think I was going to elaborate on that, add more information, but I guess I forgot to do so.
24
Okay.
25
Then there's the section on weather control programs.
26
'This made interesting reading, but your ideas didn't really lead on from each other.'
27
Did you write a plan before you did this?
28
Err.. no. Well, you really ought to.
29
Here's an example.
30
You talk about experiments to control hurricanes.
31
Then you write about rain making experiments.
32
And then for no apparent reason you go back to talking about hurricane control.
33
So, a bit messy?
34
A bit, yes.
35
Next you go on to talk about something called cloud seeding.
36
Great, you gave a good, clear explanation about what cloud seeding is, that it's a way of using science and chemistry to make clouds produce rain
37
and you give some examples of where it's been used.
38
So that section's alright?
39
Ah, well, listen to this.
40
The chemical silver nitrate is introduced into clouds to encourage them to produce rain.
41
silver nitrate Oh, that was careless.
42
I meant silver iodide.
43
Exactly.
44
I would hate to think what might happen if you started firing silver nitrate into clouds.
45
Ha!
46
Ha!
47
Okay.
48
Finally, the conclusion.
49
I always have problems with the conclusion.
50
I never really know what to say.
51
Well, you summarise your main points and give a few opinions, which is great.
52
But you then start talking about environmental systems.
53
This was not only in the wrong place, but I couldn't see where it fitted in with the rest of the essay generally.
54
Right, so there's a bit of room for improvement then.
55
Unit 9, Track 21.
56
Alright, let's go back to the section in your essay on cloud seeding.
57
Apart from your silver nitrate, silver iodide mistake, you've missed a few bits out. Have I?
58
I'm afraid so.
59
What I'd like you to do is talk me through the process of cloud seeding, what it involves and so on.
60
And I'll stop you if you've forgotten something.
61
Okay?
62
Fine.
63
Well, first of all, silver nitri - er, iodide, is fired into the cloud from the ground using a rocket.
64
Good And you could mention that sometimes it's dropped from above by aircraft.
65
Right.
66
And this is the first stage, the primary stage, which is called static seeding.
67
The silver iodide causes a chemical reaction with the tiny water drops in the cloud and they freeze.
68
Okay, so you've got millions of tiny ice particles because the water droplets in the cloud freeze.
69
What happens next?
70
Next, there's a process called rhyming.
71
R -I -M -I -N -G.
72
That's when the ice particles, well, they join up to form bigger pieces of ice, and when they're heavy enough,
73
they fall from the sky.
74
Good and then Well, as they fall, they turn to rain or snow, And, uh...
75
Well, that's it, isn't it?
76
Well, usually, yes, but you've mentioned that there's a first stage, a primary stage, so surely you should have mentioned...
77
Oh, the secondary stage!
78
Which is known as?
79
Dynamic seeding, of course.
80
How could I have left that bit out?
81
Let me think.
82
Okay, so the water droplets turn to ice and...
83
Uh...
84
What happens when water freezes, when anything freezes for that matter?
85
Something that may seem surprising?
86
Oh, of course.
87
It releases heat.
88
Mm -hmm, exactly.
89
It releases heat.
90
And what can happen to a cloud when freezing water inside it does this?
91
The cloud gets bigger and contains even more moisture.
92
Exactly.
93
And not only do they become bigger, but they also...
94
They, uh...
95
Produce storms.
96
No, hang on, that's not right.
97
They last longer, that's it.
98
Right.
99
They last longer.
100
Which means they can be seeded again to produce even more rain.

Why practice speaking with this video?

Utilizing this video for speaking practice provides an excellent opportunity to engage with real-life discussions on contemporary topics such as weather control and global warming. This context is particularly beneficial for English learners, as it exposes you to formal academic discourse, improving your ability to articulate complex ideas. By shadowing the dialogue, you can enhance your fluency and gain confidence in discussing intricate subjects. Moreover, conversing about current and relevant issues makes the practice more interesting and relatable, allowing you to expand your vocabulary in a meaningful way.

Grammar & Expressions in Context

In the transcript, several grammatical structures and expressions stand out that are beneficial for English learners:

  • Conditional phrases: The speaker mentions, "if you started firing silver nitrate into clouds." This structure is essential in English as it allows you to express hypothetical situations.
  • Present perfect tense: The phrase "there is a lot of evidence" emphasizes the use of the present perfect to discuss ongoing relevance, which is key in formal writing and speaking.
  • Comparatives and contrasts: The suggestion to clarify "many experts believe" helps highlight the importance of using caution when expressing certainty—this is vital for academic discussions.
  • Transition phrases: The use of "in fact" and "here's an example" is effective in linking ideas smoothly and keeping the flow of conversation intact.

By focusing on these elements, learners practicing through this shadowing site can significantly enhance their grammar usage in both spoken and written contexts.

Common Pronunciation Traps

Paying attention to pronunciation in this video can help you avoid common pitfalls. Certain words and phrases that may pose challenges include:

  • Cloud seeding: Ensure to pronounce "seeding" clearly to avoid confusion with "seating," which can change the meaning altogether.
  • Silver iodide: This scientific term requires careful enunciation, as mispronouncing it may lead to misunderstanding.
  • Extreme weather: The emphasis on 'extreme' can sometimes blend into the following word when spoken quickly. Practice this to ensure clarity.

Engaging with tricky words like these through repeated shadow speak exercises can vastly improve your English pronunciation and ensure that you can communicate effectively. Utilizing resources like shadowspeak can further refine your speaking skills and increase your confidence in various conversational contexts.

What is the Shadowing Technique?

Shadowing is a science-backed language learning technique originally developed for professional interpreter training and popularized by polyglot Dr. Alexander Arguelles. The method is simple but powerful: you listen to native English audio and immediately repeat it out loud — like a shadow following the speaker with just a 1–2 second delay. Unlike passive listening or grammar drills, shadowing forces your brain and mouth muscles to simultaneously process and reproduce real speech patterns. Research shows it significantly improves pronunciation accuracy, intonation, rhythm, connected speech, listening comprehension, and speaking fluency — making it one of the most effective methods for IELTS Speaking preparation and real-world English communication.
