1
The Lighthouse Lab I'm going to go ahead and put it in the middle of the middle.
2
Thank you.
3
Oh, hey there.
4
If you've ever taken a bath before, you'll have noticed that some things Like this rubber duck, Stay on top of the water.
5
They float.
6
Other things, like this bath plug, sink to the bottom of the bath.
7
They sink in water. So what causes this?
8
Well, the simple answer has to do with density.
9
Density is the amount of mass an object has in a given volume.
10
The more mass an object has in a given volume, the more dense it is.
11
Objects that are more dense than water will sink to the bottom.
12
But objects that are less dense than water will float on the top.
13
Our rubber duckies volume is mostly made up of air which is less dense than water.
14
That's why it floats on top.
15
Take a look at these objects.
16
Let's make predictions about which ones will float or sink when placed in this bath of water.
17
Thank you.
18
This is a ball of modelling clay.
19
Hmm, it feels pretty heavy.
20
I think it might sink.
21
What do you think?
22
Yep.
23
It's definitely more dense than water.
24
Thank you.
25
What about this metal coin?
26
Metal is pretty heavy.
27
I think this is definitely going to sink in water.
28
Yep.
29
Definitely more dense than water.
30
This polystyrene ball is very light.
31
I think this is definitely less dense than the water.
32
What do you think?
33
Yep.
34
It floats.
35
What about this ping pong ball?
36
It feels very light too.
37
I think it's less dense than water.
38
Yep.
39
It floats.
40
What about this glass marble?
41
Hmm.
42
Yep, definitely more dense than the water.
43
This is a wooden block.
44
Hmm.
45
I'm not sure about this one.
46
What do you think?
47
Wow, it floats.
48
So the wooden block is less dense than water.
49
That was fun, wasn't it, rubber ducky?
50
What's that?
51
You want to go for another swim?
52
Here you go.
53

इस पाठ की शब्दावली और बोलने के सुझाव

इस वीडियो में शैडोइंग के लिए 54 वाक्य और 348 शब्द हैं। बोला गया हिस्सा 3:17 लंबा है। वक्ता धीरे बोलता है, लगभग 106 शब्द प्रति मिनट, इसलिए हर ध्वनि की नकल करने का समय मिलता है। केवल 79% शब्द अंग्रेज़ी के 3,000 सबसे आम शब्दों में से हैं, इसलिए शब्दावली कठिन है।

ध्यान देने योग्य उच्चारण

वक्ता 5 बार संक्षिप्त रूपों का प्रयोग करता है, जैसे I'm, wasn't, you'll। इन्हें वैसे ही छोटा बोलें जैसा आप सुनते हैं।

इस वीडियो से अभ्यास कैसे करें

  1. पहले बिना बोले पूरा वीडियो एक बार सुनें और जो शब्द नहीं आते उन्हें लिख लें।
  2. सामान्य गति पर एक-एक वाक्य की शैडोइंग करें और हर वाक्य तब तक दोहराएँ जब तक आपकी लय वक्ता से न मिल जाए।
  3. अपनी आवाज़ रिकॉर्ड करें और मूल से तुलना करें, ख़ासकर dense, float, bath जैसे शब्दों पर ध्यान दें।

इस वीडियो का व्याकरण

वक्ता जिन संरचनाओं का सबसे अधिक प्रयोग करता है, वीडियो के असली शब्दों के साथ:

संरचनावीडियो में
Comparatives -er than / more … than — दो चीज़ों की तुलनाmore dense than · less dense than
“will” से भविष्य will + क्रिया — फ़ैसला, वादा या अनुमानyou'll have · will sink · will float
“going to” से भविष्य be going to + क्रिया — योजना या जो साफ़ होने वाला हैI'm going to go · is definitely going to sink

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।
