electricity is from natural resources such as coal， and these resources are
limited because they are not renewable.Therefore， we must save them， and
my following suggestions will greatly reduce everyone’s electricity usage.





　　First， please remember to turn off the lights when you don’t need
them.Second， try to use electronic products as little as possible and do not
overuse them.Third， use new products that consume less electricity， such as
new types of light bulbs.　　　　　　　　　　　
If everyone can do these things， the world will become better and better.

　　When the wind blows， tree leaves move with it.What if we could
“catch” the energy made by these leaves？ A French scientist thought about
this and made the Wind Tree.
A
　　The Wind Tree is not a real tree.It just looks like one， with a white body
and around 36 green “leaves”.The “leaves” are blades （扇叶）which
can turn in the wind.When they turn， they create electricity， and then the
machine collects it.The Wind Tree is like a wind turbine（风力涡轮机），
but it’s much smaller.It’s about 5 to 10 metres tall and easy to build.
　　Usually， the Wind Tree can make 18，000 kWh（千瓦时） of energy in
a year.That’s enough to power a home of four people.If the wind is
stronger， it can make a lot more electricity—about twice at most.
　　Wind turbines may hurt birds because they may hit the blades by
accident.But the Wind Tree doesn’t have this problem.The loud wind
turbines usually sit on hills far away from people.But the Wind Tree is
quiet.People can have them in gardens or city parks.
（　B　）1.Why did the French scientist make Wind Tree？
A. To move tree leaves quickly.
B. To make more electricity.
C. To help wind blow strongly.
D. To make gardens beautiful.

　　Meet three inventors who have had useful ideas from a young age！
B
　　The 14－year－old Remya Jose from India found that it took much time
to wash clothes by hand.So Remya studied how a normal washing machine
worked.Then she took some recycled bicycle parts and used them to build her
own machine.Remya’s washing machine is easy to use.The invention saves
lots of time and helps people to stay fit， too.It’s useful in areas with little or
no electricity.At the age of 15， Ann Makosinski from Canada heard her
friend in the Philippines was having problems doing her homework because
she didn’t have reliable（可靠的） electricity at home in the evening.She
wanted to help her friend， so she invented a flashlight to help her.The
flashlight works from the heat of your hands when you hold it， so it doesn’t
need expensive batteries or electricity.
　　As a young teenager， Kelvin Doe began to teach himself
engineering.There were often serious problems with the electricity supply in
his city， and this made daily life difficult for his family and friends.At 13，
Kelvin started to invent and build special batteries.He made the batteries
from acid（酸）， soda， and recycled metal parts that he found in recycle
bins.The energy from these produced electricity for the homes in his
community.Kelvin believes if you pay attention to doing one thing， you can
do an invention perfectly.
（　C　）6.What are the advantages of Remya’s washing machine？
①It’s easy to use.　②It saves much time.　③It helps people keep fit.　④It
saves much water.
A. ①③④ B. ②③④
C. ①②③ D. ①②④
C
（　C　）7.What does the underlined word “this” refer to？
A. The energy of the batteries.
B. The material of the batteries.
C. The electricity problem.
D. The experience of learning engineering.
C
（　B　）8.The three inventors made inventions to 　　　　.
A. make money for their families
B. find the solution to a problem
C. become famous in their countries
D. win an engineering prize
B
（　D　）9.What did the three inventions have in common？
A. They were made to produce light.
B. They were made from recycled rubbish.
C. They made the price of electricity lower.
D. They were useful in places without reliable electricity.

　　Last weekend， my family decided to have an electricity－free day as an
experiment.We wanted to see how our lives would be different without this
modern convenience.
　　As soon as we woke up in the morning， we realized how much we
depended on electricity.There was no electric kettle to make our morning
tea， so we had to use the gas stove.It took a bit longer， but we
managed.When it came to getting dressed， there was no electric iron to
smooth out our clothes.We had to wear them a bit wrinkled.
　　During the day， we couldn’t use our usual entertainment devices.The
TV was off， and our smartphones quickly ran out of battery since we
couldn’t charge them.We couldn’t play video games or watch funny videos on
the Internet.Instead， we went outside for a walk.The fresh air and beautiful
scenery made us forget about our dependence on electricity for a while.
　　When it got dark， things became more challenging.There were no
electric lights in the house.We had to use candles， which made the house feel
a bit spooky.It was also difficult to read or do any work by
candlelight.Cooking dinner was a problem too.We couldn’t use the
microwave or the electric oven.We had to rely on the gas stove again， but it
was hard to control the heat precisely.
　　However， this electricity－free day also had some positive aspects.We
spent more time talking to each other without the distraction of electronic
devices.We played board games together， which was a lot of fun.It made us
realize that we didn’t always need electricity to enjoy ourselves.
　　In the end， we were all relieved when we could turn the electricity back
on the next day.But this experience taught us a valuable lesson about how
much we rely on electricity and how we should appreciate it more.
（　A　）11.Why did the family have an electricity－free day？
A. As an experiment to see the difference without electricity.
B. To save money.
C. Because there was a power cut.
D. Because they didn’t like using electricity.

（　C　）12.What was the problem with making tea in the morning？
