三、阅读理解。
A
　　There is not enough oil in the world now. As time goes by，
it becomes less and less， so what are we going to do when it
runs out？ Perhaps we will go back to using horses， carriages
and bicycles.
　　In the Second World War， some people didn’t use gas
made from petroleum(石油) in their cars. They made gas from
wood and plants instead. The car didn’t go fast， but they ran，
so this was better than nothing. However， in the future， we
can’t cut down all our trees to make gas； we need our trees for
other things， too.
　　Besides different types of gas， we can also use electricity to
run our cars， but first we must make the electricity！ Some
countries have coal(煤) and they make electricity with that， but
we might not always have coal， either. Other countries have
big， strong rivers， and they can use the power of water to turn
turbines(涡轮机) and make electricity more easily and cheaply.
　　We are also able to get power from the ocean tides. We put
turbines into the mouth of the river. When the tide comes in，
the water turns the turbines and when it goes out， it turns them
again.
　　Which of these ways will be used to run our cars in the
future？
(　B　)1. When might people have to go back to using horses
and carriages？
A. When they are poor.
B. When they run out of oil.
C. When they need more exercise.
D. When there aren’t any big trees in the world.
【解析】细节理解题。根据第一段第二、三句“…so what are
we going to do when it runs out？ Perhaps we will go back to
using horses， carriages and bicycles.”可知答案，故选B。
B
(　C　)2. What did some people use to make gas in the Second
World War？
A. Water. B. Coal.
C. Wood and plants. D. Tides.
【解析】细节理解题。根据第二段第一、二句“In the Second
World War， some people didn’t use gas made from petroleum
in their cars. They made gas from wood and plants instead.”可
知答案，故选C。
C
(　B　)3. According to the passage， which of the following
statements is true？
A. There is more petroleum than we can use now.
B. Trees are needed for some other things besides making gas.
C. We got electricity from ocean tides in the old days.
D. Gas wasn’t used to run cars in the Second World War.
【解析】细节理解题。根据第二段最后一句“…we need our
trees for other things， too.”描述，故选B。
B
(　B　)4. What is the passage mainly about？
A. How to run our cars.
B. What to do when oil runs out.
C. Different types of gas.
D. The ways to make electricity.
【解析】主旨大意题。全文围绕“石油用完了我们该怎么办”
这一核心问题展开，因此B是最佳答案。
B
B
　　We all know electricity is useful in our lives. We get
electricity by burning coal， oil and natural gas. But these ways
pollute the air. Saving electricity means protecting our
environment. What can we do to save electricity？
When you leave a room， you should guarantee that you
turn off lights and other machines， such as TVs， computers
and radios. It is a good habit to save electricity.
Keep doors and windows closed when the air conditioner is
on. If you open doors and windows when using the air
conditioner， you will find more money on your electricity bill
compared with doors and windows closed.
Turn off the tap when brushing your teeth and take shorter
showers. These will help save water and electricity as well.
In the day， don’t turn on lights if possible. Use a larger
one instead of a few small ones.
Decide what you want from the fridge before opening it， so
you won’t waste electricity by looking inside and keeping the
door open. Before putting hot food into the fridge， cool it first.
Cook several dishes in the oven(烤箱) at the same time. And
keep the oven door closed until they are OK.
Put enough clothes in the washing machine. Try to use cool
water to wash them.
(　D　)1. What does the underlined word “guarantee” mean
in Paragraph 2？
A. Make up. B. Feel like.
C. Help out. D. Make sure.
【解析】词义猜测题。根据画线词所在句下一句“It is a good
habit to save electricity.”可知，画线词指“确保”，故选D。
D
(　C　)2. Why should we keep doors and windows closed when
the air conditioner is on according to the passage？
A. The air outside is bad for health.
B. The temperature inside will be more comfortable.
C. It needs more electricity with doors or windows open.
D. Opening doors and windows is bad for the air conditioner.
C
【解析】推理判断题。根据第三段第二句“If you open doors
and windows when using the air conditioner， you will find more
money on your electricity bill compared with doors and windows
closed.”开空调时开着门和窗户需要付很多的电费，即会消耗
更多的电，故选C。
(　B　)3. What can we do if we want to save electricity？
A. Use more small lights.
B. Put cool food into the fridge.
C. Leave the radio on when not using it.
D. Put fewer clothes in the washing machine.
【解析】细节理解题。根据第六段最后一句“Before putting
hot food into the fridge， cool it first.”可知，放凉的食物进冰
箱可以避免冰箱耗费更多电力来降温，从而节约用电，故选B。
B
(　A　)4. What is the passage mainly about？
A. The ways to save electricity.

范文一(基础版)：
Let’s save energy









Every summer， Guangzhou uses more energy， and energy
waste is getting worse. Energy is very important. We can’t live
without it—factories and our daily lives all need energy.
But some people waste energy. They often leave lights on when leaving rooms and keep computers running when they’re
unused.
To save energy， we can turn off appliances in time and use
energy-saving bulbs. At home， we should pull plugs when
appliances are not used. Let’s save energy together.
范文二(提升版)：
Let’s save energy




As summer comes， Guangzhou’s energy consumption has
increased sharply， and energy waste has become a serious
problem. Energy is essential for our life： It powers our lights，
air conditioners and factories.







However， many people waste energy. For example， they
leave lights on in empty rooms， and some even keep air
conditioners on when going out. Also， some families use too
many electrical appliances at the same time.
To solve these， we can use energy-saving appliances and
turn off lights when not needed. At home， we can set air
conditioners to 26 ℃. Let’s call on everyone to save energy.(共13张PPT)

appliance.

off the lights when you leave a room； use energy－saving bulbs； don’t leave the TV or computer on when you’re not using them； wash clothes in cold water when possible. Saving electricity not only saves money but also protects the environment.
