It’s hard to (1) believe that just 200 years ago our main energy source was wood. Now we have a wealth of energy sources to choose from, including a growing range of (2) renewable energy technologies.
But what does the future hold? How can we keep (3) supplying energy to an ever-growing population? How much will it cost?
And what impact will the energy choices we make have on our living conditions and our planet?
In a report this year, the Internet Energy Agency experts electricity generation from renewable energy (4) sources to increase from 21 percent in 2012 to 33 percent by 2040. Morever, as battery technology inproves, it will be better able to support renewable energy sources, such as (5) solar and wind power.
Innovation in energy storage has already resulted in graphene technology used in batteries, which may be able to store more energy than existing lithium batteries.
Fossil fuel is the most common source of energy today, but it is not considered clean energy. There are various other sources of alternative energy that must be incorporated if the next generations are expected to have energy. Water, wind, the internal heat of the earth, and the sun are all being harnessed to create energy. Geothermal energy and solar energy are more common. Homes are being heated and cooled, cars are being driven, and electricity is used all from these various alternative sources of energy. All are examples of clean energy, which is better for the environment because it does not cause pollution.

Tạm dịch bài đọc:
Chào cả lớp. Hôm nay tôi muốn nói với các bạn về hai nguồn năng lượng. Chúng là những nguồn không thể tái tạo và những nguồn có thể tái tạo.
Các nguồn không thể tái tạo là than đá, dầu mỏ và khí đốt tự nhiên. Chúng ta có thể sử dụng những nguồn này để sản xuất năng lượng. Chúng rẻ và dễ sử dụng. Mọi người sử dụng chúng rất nhiều. Nhưng chúng rất hạn chế và sẽ hết sớm.
Các nguồn tái tạo đến từ mặt trời, gió hoặc nước. Khi năng lượng đến từ mặt trời, chúng ta gọi nó là năng lượng mặt trời. Năng lượng gió đến từ gió, và năng lượng thủy điện đến từ nước. Nguồn tái tạo có sẵn, sạch sẽ và an toàn để sử dụng. Nhưng chúng đắt tiền để sản xuất.
Trong tương lai, chúng ta sẽ dựa nhiều hơn vào các nguồn năng lượng tái tạo. Chúng tốt hơn cho môi trường và chúng sẽ không cạn kiệt.
1. Nguồn không tái tạo được rẻ và _________.
A. có sẵn
B. dễ sử dụng
C. đắt
2. ________nhận được từ mặt trời, gió hoặc nước.
A. Nguồn tái tạo
B. Tất cả các nguồn năng lượng
C. Các nguồn không thể tái tạo
3. Khi năng lượng đến từ nước, chúng ta gọi nó là_________.
A. năng lượng gió
B. năng lượng mặt trời
C. năng lượng thủy
4. Các nguồn năng lượng tái tạo tốt hơn cho ____.
A. môi trường
B. xe của chúng tôi
C. năng lượng thủy
1. B
Non – renewable sources are cheap and easy to use.
(Năng lượng không thể tái tạo thì rẻ và dễ sử dụng.)
Thông tin: Non-renewable sources are coal, oil and natural gas. ... They are cheap and easy to use.
(Các nguồn không thể tái tạo là than đá, dầu mỏ và khí đốt tự nhiên. ... Chúng rẻ và dễ sử dụng.)
2. ARenewable sources come from the sun, wind or water.
(Các nguồn năng lượng có thể tái tạo đến từ mặt trời, gió và nước.)
Thông tin: Renewable sources come from the sun, wind or water.
(Các nguồn tái tạo đến từ mặt trời, gió hoặc nước.)
3. C
When energy comes from water, we call it hydro energy.
(Khi năng lượng đến từ nước, chúng ta gọi nó là năng lượng thủy điện.)
Thông tin: Wind energy comes from the wind, and hydro energy comes from water.
(Năng lượng gió đến từ gió, và năng lượng thủy điện đến từ nước.)
4. A
Renewable energy sources are better for the environment.
(Các nguồn năng lượng có thể tái tạo thì tốt hơn cho môi trường.)
Thông tin: In the future we will rely more on renewable energy sources. They are better for the environment and they will not run out.
(Trong tương lai, chúng tôi sẽ dựa nhiều hơn vào các nguồn năng lượng tái tạo. Chúng tốt hơn cho môi trường và chúng sẽ không cạn kiệt.)
Read the passage and choose the best answer
The sun is our nearest star, and all of our energy comes from it. The sun sends out very large amounts of energy every day. We call this energy solar energy or radiant energy. With out the sun, life on earth would not exist because our planet would be totally frozen. We use this solar energy in many different ways. The sunlight lets us see and warms us. Plants use the light from the sun to grow. They store it as chemical energy. The energy is stored in their roots, fruits, and leaves. This energy feeds every living thing on the earth. When humans and animals eat plants, and the food made from plants, we store the energy in our bodies, in our muscles and in our brain cells.
1. Which does all of our energy come from?
A. the sun B. the wind C. the water D. nuclear power
2. If we didn’t have the sun, what would happen?
A. life would not exist B. we live happily C. life would exist D. life is hotter
3. Why do plants use the light from the sun?
A. to grow B. to store C. to make food D. to run
4. Where do we store the energy?
A. in the shops B. in our bodies C. in the roots D. in the leaves
Read the passage below and an answer the question :
We can develop alternative sources of energy,and unless we'll never succeed.instead of burning fossil fuels we should be concentrating on more economic uses of electricity because electricity can be produced from any source of energy. If we didn't waste so much energy,our resources would last longer. We can save more energy by conservativation than we can produce for the same money. Unless we do research on solar energy wind power tidal power hydroelectric plants.... Our fossil fuels will run out and we'll all freeze starve to dealth . Many countries are spending much more time and money on research because the energy from the sun the waves and the winds last forever.we really won't survive unless we start working on cleaner safer scour of energy .
1 Can electricity be produced from any sources of energy?
Yes, it can.
2 What would happen if we didn't waste so much energy?
If we didn't waste so much energy, our resources would last longer.
3 Why are many countries spending much more time and money doing research on energy from the sun the waves and the wind?
Because the energy from the sun the waves and the winds last forever.
4 What will happen unless we start working on cleanr and safer sources of energy?
We really won't survive unless we start working on cleaner and safer scources of energy
1.How many types of energy sources are mentioned in the text? What are they?
Two. They are renewable and non-renewable.
2.What are the disadvantages of hydro and nuclear power?
Hydro power is limited because dams cannot be built in certain areas. Nuclear power is dangerous.
3.Why do you think the wind and the sun are called alternative sources of energy?
Because they are natural sources of power and we use them instead of non-renewable sources to get the electricity we need.
4.What types of energy does Viet Nam use most?
We use non-renewable sources of energy the most but we are increasingly using hydro power.
5.What does the professor think Viet Nam will use more in the future?
He thinks Viet Nam will use the wind and the sun as alternative sources of energy in the future

These (4) ____kinds______ of energy will not cause (5) _____pollution_____ or waste natural resources. (6) _____Renewable_____ power is one of them. It's currently the cheapest source of large-scale renewable energy.
Most wind energy is produced from turbines that have three 60-meter-long blades. The wind spins the blades, which turn a shaft connected to a generator that produces (7) ____electricity______. Now, mass production and technology advances are (8) ______made____ turbines cheaper. In 2000, cumulative wind capacity (9) ____of ______the world was 17,000 megawatts. Fifteen years later, this number increased sharply to 430,000 megawatts.
