“Electricity gives us power. It flows through wires. It’s like water, in a way,” said Benny.
“You’re right! Electricity comes into our flat through thin wires. These are connected to cables

British official.
CFLs use 67 percent 6.________ electricity than the older bulbs. They last up to 10 times

二、阅读理解
A
Here I want to tell you some information about water.
Water covers (覆盖） most of our planet. People can find it in oceans, lakes, and rivers, and
under the ground. Water moves in the environment by evaporation, condensation, and
precipitation. The warm Sun helps water change into vapour and rise up into the sky. It is
evaporation. The vapour in the air forms clouds in the sky. It is condensation. When the clouds
get heavy enough, the water falls back to the ground as rain or snow. This is precipitation.
28
Ocean water has too much salt in it. Much of the water travels far over land. When it travels
over land, the water picks up salt from the rocks and soil. About 97.5% of the Earths water is
salty water. It is expensive to take salt out from water.
All people need clean water. They need it for drinking, for cooking, and for bathing. Some
people in a village in South America did not have clean water. Their water was &11 of oil and
dirty things. People there got sick when they drank the water. Other people heard about the
problem. They sent empty water tanks (储水池）to the village. Rainwater fell into the tanks.
Now the people in that village have clean water.
( )41. What helps water change into vapour?
A. The Sun. B. The Moon.
C. The Earth. D. The star.
( )42. Why can we NOT drink ocean water?
A. Because it is salty.
B. Because we don’t have much ocean water.
C. Because it is far away from us.
D. Because it is valuable.
( )43. What’s the problem of the people in the village in South America?
A. It never rains in their village.
B. Their drinking water was too dirty and not safe.
C. They didn’t know how to use rainwater.
D. They were too poor to buy water.
29
( )44. The writer wrote the last paragraph mainly to tell us ______.
A. many people in the world are poor
B. clean water is important to people .
C. we should help poor people
D. we should save rainwater
( )45. Where may the writer get the information?
A. In a travel guide.
B. In a storybook.
C. In a cookbook.
D. On the Internet
B
If you travel to London to watch the 2012 Olympics, you will be able to walk on a new
kind of sidewalk (人行道). It’s made of special slabs (平板). It can change the energy from
people’s footsteps (脚步) into electricity (电).
This new invention is called PaveGen. Laurence Kemball-Cook, a 25-year-old student,
designed it. The green slab gets energy from people’s steps and passes electricity to lamps (灯).
So, when people walk on the slabs, the sidewalk will light up. Each step produces enough
electricity to keep a lamp on for 30 seconds.
Looking to the future, Kemball-Cook would like to introduce the invention to more
countries.
“Every person takes about 150 million steps in their lifetime. Just imagine how much
electricity we will produce,” he said.
30
( ) 1. Where can you walk on the new kind of sidewalk?
A. US B. UK C. Canada D. Australia
( ) 2. Who designed the new sidewalk?
A. a scientist B. a teacher C. a cleaner D. a student
( ) 3. Where does the green slab get energy?
A. From people’s voice C. From the Sun
B. From people’s steps D. From the wind
( ) 4. What is electricity from the green slab used for?
A. Lamps B. Cars C. Fridges D. Air conditioners
( ) 5. Which of the following is NOT true according to the passage?
A. The new sidewalk is made of special slabs.
B. The name of the new invention is PaveGen.
C. When people walk on the slabs, the sidewalk will light up.
D. Each person takes about 150 billion steps in their lifetime.
C
Drinking sugary soda (碳酸饮料) gives you more energy. Can you imagine sugar might
power (提供能量) your cellphone (手机)?US scientists have now found a way to turn sugar into
electricity. The new idea is about fuel cells using chemical reactions(化 学 反 应 ) to produce
electricity.
What can make fuel cells? Scientists found that enzymes (酶) might be able to. In the cells of
living things, enzymes make chemical reactions possible.
31
Scientists had tried using enzymes in fuel cells before, but they had trouble keeping the
electricity going. That’s because the enzymes in fuel cells break down (分解) faster than they
can be replaced (取代).
Luckily scientists had found a way to solve the problem. Now they can make an enzyme last
for months instead of days.
The scientists are now trying to use different enzymes so as to get more power from sugar.
