शैडोइंग अभ्यास: Bill Gates - Population - Vaccines - वीडियो के साथ अंग्रेजी बोलना सीखें

This equation has four factors, a little bit of multiplication.

So you've got a thing on the left, CO2, that you want to get to zero.

And that's going to be based on the number of people, the services each person's using on average, the energy on average for each service,

and the CO2 being put out per unit of energy.

So let's look at each one of these and see how we can get this down to zero.

Probably one of these numbers is going to have to get pretty near to zero.

That's back from high school algebra.

But let's take a look.

First, we've got population.

The world today has 6.8 billion people.

That's headed up to about 9 billion.

Now, if we do a really great job on new vaccines, healthcare, reproductive health services, we could lower that by perhaps 10 or 15%.

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।
