years. It could be getting warmer on its own, but many scientists think that people
are making the Earth warmer by making a greenhouse effect (湿室效应).The
greenhouse effect is important. Without it, the Earth would not be warm enough
for us to live on. But just a little warmer than it is now could cause problems for
humans, plants and animals.
Many of the things we do every day can change the Earth"s temperature by
sending greenhouse gases (废气)into the air. We send greenhouse gases into the
air when we watch TV, turn on lights, dry hair, play video games, wash or dry
our clothes or drive cars. The rubbish (waste) from factories and homes also
produces greenhouse gases.
Even a small change in temperature can affect (影响)our weather. This can
cause changes in the sea levels, the air, flooding and our fresh water.
The change in the temperature can also cause changes in the living places
for animals and plants, endangering many animals.
Global warming (全球变暖)is a big problem, and every little bit we do
can help. We can save electricity. We can save energy in other ways such as by
taking buses or walking rather than driving cars. We can recycle to reduce the
rubbish and save natural resources such as trees, oil and metals. We can buy
products that don"t do bad to the environment and we can turn to solar energy.
Remember the little bit that you do will bring a better world.
B. Walking to school.
C. Driving a car.
D. Watching TV.

animals lived beside the water, which was full of fish. Now there are few birds, animals, and fish.
The lake water is polluted (污染的). It is in a colour of dirty brown, and it is filled with strange
plants.
How does this happen? First we must think about how water gets into Lake Ponkapog. When
it rains, water comes into the lake from all around. In the past there were forests all around Lake
Ponkapog so the rain water was clean.
Now there are many homes around the lake. People often use chemicals (化学品) in their
gardens. They use other chemicals inside their houses for cleaning or killing insects (昆虫). There
are also many businesses. Businesses use chemicals in their machines or shops. Other chemicals
fall onto the ground from cars or trucks. When it rains, the rain water picks up all the chemicals
from homes and businesses and then carries them into the lake. They pollute the water and kill
the animals.
Boats on the lake are also a problem. Lake Ponkapog is a popular place for motorboats. But
oil and gas (油和汽) from boats often get into the lake. So more bad chemicals go into the water
this way.
People in Hartwell are worried. They love their lake and want to save it. Will it possible? A
dean lake must have dean rainwater going into it. Clean rainwater is possible only if people are
more careful about chemicals at home and at work. They must also be more careful about gas
and oil and other chemicals on the ground. And they mustn"t use motorboats any more on the
lake. All these may change people"s lives. Only then can Lake Ponkapog he a beautiful, clean
lake again.

3. Cleaner rainwater will mean ______.

D. a dirtier lake

D. use more motorboats on the lake
5. The passage is about ______.
B. why the water is dirty in Lake Ponkapog
C. clean rainwater
D. dirty lakes
The bicycle is one of the simplest (最简单的) yet most useful inventions in the world. What is most
surprising is that it was not invented earlier, 1 the great inventor Leonardo da Vinci had drawn pictures
for bicycles and also for flying machines and some other things. Those things were not produced 2 long after he died.
A person riding a bicycle use 3 energy(能量)to make the bicycle move, and there is no pollution
at all when you are riding. Even so, m developed 4 , most people don"t travel to work by bicycle. It is
not because the bicycles are expensive or people feel 5 if they ride to work. It"s because 6 cars on
the roads becomes larger. It certainly becomes 7 to ride a bi-cycle. As a result, more people put their
bicycles away and go to work 8 their cars and, in this way, the situation(情形)is made more serious. 9 the best way to make riding safer and more popular is to create paths(开设通道)only for bicycles, and
to make 10 so difficult and expensive for drivers to take their cars into the city that they will go back
to use their bicycles.
