本次写作内容是一封书信，信中首
先要介绍你所在城市存在有哪些环境问
题，是谁造成的这些问题，然后提出解
决这些环境问题的方法和措施，可以结
合3a中列举的问题和前面学过的解决办
法来完成这封信。
Dear Sir/ Madam,
Environmental problems are becoming more
and more serious all over the world.
With the development of the society, there are
too many cars on the streets in our city. Cars
have made the air unhealthy for people to
breathe. Black smoke and poisonous gas are
given off by factories. Factories also put waste
into the river. And wherever we go, we can find
rubbish.
Now more and more people have realized
these problems. I think that governments
should close down the factories and develop
laws to stop people from driving cars every
day. I suggest everyone in this town should
help to clean up the river and the streets. We
should call on everyone in the town to throw
rubbish in the dustbins.
I hope the problem will be solved in the
near future and our home will become better
and better.

Bicycle Sharing
With the development of technology,
bicycle sharing comes into people's lives.
It becomes more and more popular . At
the same time, there are also some
problems .
On one side, bicycle sharing makes
it very convenient of people traveling.
You can find a bicycle anywhere at
any time when you want to go out for
a cycling, and the price of one trip is
very low. It can save time for people.
On the other side, its management
is not perfect. Even kids can open
the lock and ride the bicycle.It is
very dangerous. What's more, many
people sometimes break it or throw
it to the river .
In my opinion, we should take a
developing view about bicycle sharing.
It is helpful to us. So we should
protect the bike. The government
should make some laws to protect this
market to avoid its disadvantages.
