Today we can see that many people are cutting down the trees in the
forests. A lot of
16
lands have become deserts. If we read newspapers, we’ll learn that
the forests on the earth are getting smaller
17
. We are cutting down large numbers of trees
18 we need wood and farmland. Some
scientists say that there will not be any great forests
19 20 or 30 years.
What will happen if the forests disappear? A lot of plants will die
and the animals will
20
their homes. In many places the new farmland will soon look
21 the old desert. Crops will
not grow there. There won’t be enough
22
, and the weather will get hot and dry. If the climate
of the earth changes, life will be
23
for everyone. Our living environment will become
24 . More and more rich farmland will disappear.
We will suffer a lot from both droughts (干旱) and floods.
It’s our duty
25 the forests
well. Everyone should try his best to make a contribution (贡献) to
taking care of the forests. Stop cutting down the trees and make
the world greener!

Some people say they have a solution to the problems of car
crowding and pollution. In many cities, hundreds of people
16 bikes to work every day. In
the New York City, some bike riders have even founded a group: Bike
for a Better City. They say if more people ride bikes to work,
there would be
17 cars and
less dirty air.
For several years this group has tried to gather help for bike
riders. They want to have special roads
18
bikes only, because when bikes and cars use the
same roads, there may be accidents. Bike for a Better City thinks
if there were bike roads, more people would use bikes.
But no bike roads have been established
19
. Not everyone thinks it is a good
20
. Drivers don’t like it, and some shop owners don’t
like it,
21 . And most people live
22 far from the city
to travel by bike. Still,
23
has been done about it. On Saturdays and Sundays, the
largest open park in New York is
24
to cars, and the roads may be used by bikes only, but the
group still says this is not enough and goes on fighting
25 bike roads. I think there will be more
bike roads in the future.
