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 clean lake
must have clean 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 be a beautiful, clean lake again.

Someday little cars may take the place of today"s cars. If everyone 1
such a little car in the future, and less pollution in the air, there will be more
parking space in cities,and the streets will be 2 crowded.The space now
for one car of" the usual size can hold 3one such little car.
The little cars will 4 much less to own and to drive. Driving will
be 5 too, because these little cars can go only 50 kilometres an hour.
The cars of the future will be fine for going 6 the city, but they will not
be useful for going far away.The little car needs only two batteries (电池)
—one battery for the motor, and 7 for the horn and the lights.If we
still 8 the big cars along with the small ones,we will need to 9 two
kinds of roads. Some roads will be used 10 the big fast cars, and others
will be needed for the small , slower ones.
