[♪ INTRO] Hey there! Squeaks was just showing  me his imaginary sea monster that he drew based on some  sea monsters of the past!
2
I think it’s great!
3
I see that it has sharp teeth, big flippers, and an armored head, like the  animals we learned about before.
4
And I see you drew a picture of  you swimming next to your monster!
5
Your sea monster is HUGE!
6
But even your imaginary sea  monster doesn’t look as big as the biggest biggest animal  that’s ever actually lived!
7
Do you know what that animal is, Squeaks?
8
It’s a kind of whale called the blue  whale, and they’re still around today!
9
Blue whales can get to be over 30 meters long, about as long as 3 school buses in a row.
10
And, a blue whale’s tongue can  weigh as much as an elephant.
11
And just its heart can be as heavy as a car!
12
So, what do you think these  great big blue whales eat?
13
Fish! That’s a great guess!
14
And some whales, like beluga whales, do eat fish.
15
They have sharp teeth that they  use to catch and eat their prey.
16
But some whales, like blue  whales, don’t have teeth at all!
17
Weird, right?
18
These whales have something  called baleen instead of teeth.
19
Baleen is a bristly plate that is  stuck to the roof of the whale’s mouth.
20
It looks like a big, bristly  broom inside their mouths!
21
Oh, that’s a great question!
22
How dooes it help them eat?
23
Well, if you’ve ever seen someone cook pasta, they might have dumped it out  of the pot and into a strainer when the pasta was done cooking.
24
Water pours out of the strainer,  but the food stays inside.
25
Baleen works kind of the same way.
26
When a whale that has baleen  takes a gulp of water and food, they use their tongues to push all  the water out through the gaps, but keep the tasty food inside.
27
But if they aren’t eating  fish, what are they eating?
28
Blue whales eat tiny animals called krill!
29
Krill are so small that we need  a microscope to see them clearly.
30
That’s right, Squeaks!
31
Something as big as a blue whale  does need to eat a lot of krill!
32
And they do!
33
Adult blue whales can eat  16 tons of krill each day.
34
That’s as heavy as four elephants!
35
Isn’t it amazing that such  a huge animal eats things that are so small that we can’t even see them?!
36
Baby whales are called  calves, just like baby cows.
37
And also like cows, whale calves  drink the milk that their mothers make inside their bodies until they’re  old enough to start eating krill.
38
That’s because all whales,  including blue whales, are mammals.
39
Mammals are animals like  horses, cows, dogs, and humans.
40
And all mammals feed their newborn babies milk.
41
That’s one of the special things  that makes an animal a mammal!
42
Yes, they do look more like a  fish than like the other mammals.
43
But fish don’t feed their babies with milk, which helps us know that  whales and fish are different.
44
And there’s another important  feature that tells us that whales are mammals and definitely not fish.
45
Whales don’t have gills to  breathe in water, like fish do.
46
They have lungs, just like us!
47
So even though some whales can  hold their breath for over an hour, they have to come up to the surface of  the ocean to breathe every now and then.
48
When we breathe, air goes through  our nose or mouth and into our lungs.
49
Whales breathe using their lungs too,  but they do it in a very special way.
50
They breathe in and out through a hole on  the top of their head called a blowhole.
51
When a whale is ready to take a breath,  it comes up to the top of the water, opens its blowhole, and breathes out.
52
This is called spouting.
53
That air shoots up into the sky,  sometimes about 12 meters high!
54
That’s about as tall as six grown-ups  if they stood on each other’s shoulders.
55
Then, the whale breathes fresh  air in through its blowhole, and goes back underwater.
56
When a whale is underwater, they can pinch  their blowhole closed from the inside, and seal it shut so no water gets in.
57
But my favorite thing about blue whales  are the amazing sounds they make.
58
Blue whales, as well as  lots of other whale species, can talk to each other from really far away!
59
Sound travels really well in water,  so one whale can hear another whale making noises even if they’re  thousands of miles apart!
60
Whales make lots of sounds,  including squeaks, whistles, and long low booming sounds  that scientists call “songs.” Here’s what a blue whale’s song sounds like.
61
I think whale songs sound beautiful, too, Squeaks!
62
Oh yeah. Squeaks says he still thinks  his imaginary sea monster is pretty cool, but it’s even cooler that there are giant  blue whales out in the ocean right now, singing to each other, eating microscopic  krill, and taking care of their babies!
63
Thanks for joining me here at The Fort!
64
I hope you loved learning about  our ocean mammal friends too.

इस पाठ के बारे में

इस पाठ में, आप नीली व्हेल, उनके अद्भुत आकार और भोजन करने के तरीके के बारे में जानेंगे। आप यह सीखेंगे कि कैसे ये gigantesque जीव अपना पेट भरते हैं और उनकी शारीरिक संरचना क्या है। यह जानकारी अंग्रेजी बोलने के अभ्यास में आपकी मदद करेगी, क्योंकि आप इस अद्भुत जीव के संदर्भ में शब्दावली और वाक्य संरचना को समझ सकेंगे। इसने आपको न केवल विषय पर ज्ञान प्रदान किया बल्कि आपकी अंग्रेजी बोलने का अभ्यास भी बढ़ाया।

मुख्य शब्दावली और वाक्यांश

  • नीली व्हेल (Blue whale)
  • भोजन (Food)
  • दूध (Milk)
  • मस्तिष्क (Brain)
  • बालेन (Baleen)
  • कृल (Krill)
  • गति (Motion)
  • प्राणवायु (Breath)

अभ्यास के टिप्स

इस वीडियो को देखकर और shadowspeak अभ्यास करते समय, ध्यान दें कि बोलने की गति और ध्वनि के स्वर पर ध्यान दें। जब आप बोल रहे हों, तो थम जाएँ और हर एक शब्द को स्पष्ट रूप से उच्चारित करने का प्रयास करें। वीडियो की गति को अपने बोलने के दौरान पकड़ें, इससे आपका अंग्रेजी उच्चारण में सुधार होगा। सबसे बेहतर नतीजे पाने के लिए, पहले वीडियो को सुनें और फिर उसे दोहराएं। इस तकनीक को अंग्रेजी शैडोइंग कहा जाता है, जो आपके सुनने और बोलने के कौशल को बढ़ाने का एक बेहतरीन तरीका है।

ध्यान दें कि जैसे-जैसे आप अभ्यास करते हैं, अपनी आवाज की गति को धीरे-धीरे बढ़ाएँ। प्रारंभ में धीमे बोलने का प्रयास करें और फिर अधिकतम गति पर जाएँ, ताकि आप स्पष्ट रूप से बात कर सकें। आप इस तरीके से न केवल विषय को समझेंगे, बल्कि अपनी अंग्रेजी बोलने का अभ्यास भी कर पाएंगे।

शैडोइंग तकनीक क्या है?

शैडोइंग (Shadowing) एक विज्ञान-समर्थित भाषा सीखने की तकनीक है जो मूल रूप से पेशेवर दुभाषिया प्रशिक्षण के लिए विकसित की गई थी। विधि सरल लेकिन शक्तिशाली है: आप मूल अंग्रेज़ी ऑडियो सुनते हैं और तुरंत इसे ज़ोर से दोहराते हैं — जैसे वक्ता की छाया 1-2 सेकंड की देरी से। शोध से पता चलता है कि यह उच्चारण सटीकता, स्वर, लय, जुड़ी हुई ध्वनियाँ, सुनने की समझ और बोलने की प्रवाहशीलता में काफ़ी सुधार करता है।
