Câu 1 với câu 2 cj ko chắc lắm do tại kiến thức cũ hồi cái đó không có học kĩ lắm ^^
2. Mr Lam is giving a lecture on energy sources. Read the text and choose the best option (A, B, or C) to complete the sentences.
(Ông Lâm đang giảng bài về các nguồn năng lượng. Đọc văn bản và chọn phương án tốt nhất (A, B hoặc C) để hoàn thành các câu.)
Hello, class. Today I'd like to tell you about two energy sources. They are non-renewable sources and renewable sources.
Non-renewable sources are coal, oil and natural gas. We can use these sources to produce energy. They are cheap and easy to use. People use them a lot. But they are very limited and will run out soon.
Renewable sources come from the sun, wind or water. When energy comes from the sun, we call it solar energy. Wind energy comes from the wind, and hydro energy comes from water. Renewable sources are available, clean and safe to use. But they are expensive to produce.
In the future we will rely more on renewable energy sources. They are better for the environment and they will not run out.
1. Non – renewable sources are cheap and _________.
A. available
B. easy to use
C. expensive
2. _________come from the sun, wind or water.
A. Renewable sources
B. All energy sources
C. Non-renewable sources
3. When energy comes from water, we call it_________.
A. wind energy
B. solar energy
C. hydro energy
4. Renewable energy sources are better for_______.
A. the environment
B. our cars
C. hydro energy
I.Choose the correct word or phrase in each sentence.
1. This time next year my father (will work/ will be working) in the hydro power station.
A.will work B.will be working
2. Jane won’t be here this time tomorrow. She (will attend/ will be attending) the Conference on Green Energy.
A.will attend B.will be attending
3. My brother and I (will cycle/ will be cycled) to school to cut air pollution.
A.will cycle B.will be cycled
4. By the year 2020, people in my village (will use/ will be using) energy from the sun.
A.will use B.will be using
5. What (will we do/ will we be doing) to save electricity?
A.will we do B.will we be doing
6. What (will happen/ will be happened) to us when the non-renewable energy sources run out?
A.will happen B. will be happened
7. Wind power is a renewable source because it (can be replaced/ can replace) easily and quickly.
A.can be replaced B.can replace
8. The students in my school (will be put/ will be putting) low energy light bulbs in the school.
A.will be put B.will be putting
9. Alternative sources of energy (will be developed/ will develop) quickly.
A.will be developed B.will develop
10.The energy consumption (will be reduced/ will reduce) as much as possible.
A.will be reduced B.will reduce
Put the sentences to make a logical dialogue
A. How can we do that, Dad?
B. Sure, Dad.
C. Anh we will use renewable energy sources like solar energy.
D. I will ride a bike to school tomorrow. What else, Dad?
E. We can travel by public transport or bicycles.
F. What are non-renewable sources of energy, Dad?
G. Is it a better source of energy?
H. Ph, so they will run out.
I. Yes, it is clean and plentiful
J. Yes. That's why we have to save the energy
L. Well, those sources of energy are limited and can't be replaced after use
M. You should turn off the TV or computer when you don't use them.
=> F -> L -> H -> J -> A -> M -> B -> E -> D -> C -> G -> I
1.run out / remewable / comes / energy / from / that / sources / will / some day .
→ Renewable energy comes from that sources will run out someday
2.fuels / to / are / they / the / limited / harmful / fossil / enviroment / and / they .
→ Fossil fuels are limited and they are harmful to the enviroment.
3.can't / non- renwable / replace / enregy / resources / be / up / once / used / are / they
→ Non-renewable energy can't be replaced once they are used up resources.
4. cheap / but / releases /a lot of / when / cola / is / burned / it / pollutants .
→ Cola is cheap but releases a lot of pollutants when it is burned.
Natural fuel sources are important to us, and we are in desperate need of it. But we use it too wasteful of avf used too much, so they are slowly running out. So in the future, sooner or later, those energies will expire soon. They are gas, oil, coal, ... Then, if we do not have timely treatment, we will be severely short of raw materials. All activities will be immediately suspended, and we will be very miserable. First, we will not have electricity to light all daily activities, and they will become very difficult. The second is for cooking, we have to use the straw stoves, straw stoves, while today we often use gas stoves. There are also many other issues like raw materials for production, for moving. Next is the environment is heavily polluted after we use those energy sources. In short, the consequences are enormous. However, we can stop it by using renewable energies like wind, solar energy, tidal energy, which last forever, and they don't pollute the environment. I hope in the future everyone will use renewable energy sources to make life better.
