1)环境总体概况 environment problem is geting more and more serious.We should do something to help our environment,otherwise it is late.
2)环境恶化事例 there are a pile of garbage near the river bank .you often see people spiting in public.although many garbage can should be provided in the community,there are many people neglecting the rules,they still throw away garbage everywhere.
3)环保课程 there are many students having a lesson about environment. many teacher begin to teach students how to protect environment,and tell them how important a good environment is to us and to the whole world. there are some lecture about environment problem in primary school,and middle school and university or college school.
4)成人环保更应关注 we should teach adults,because adults neglect it more than student do.we should have a lecture in a cinema or in a hall, which enable them know about the significance of environment protection.
5)我们应该从我做起 we should protect environment by myself.for example,I can use less plastic bag or divide garbage into differents cans or taking bus or subway instead of taking a car.
A:the pictures exhibit a man is sawing down another tree in the area.
Forests in china are getting smaller and smaller.there are much flood every years in china,many wild animal have disappeared ,dessert is getting larger and larger,sandstroms are emerging in most of cities in china.
there are at least one reason to explain the issue.
people cut trees for money,they think these trees will be grow naturally and they don't need much time to care for them.
We should protect environment,if we don't protect environment ,it is getting worse and worse.we destory our earth and actually destory oursleves.those people cutting trees should be punished severely.
B:I agree with you.Once destroy has been done,it is impossible to recover.in the past 20 to 30 years,there are nartural disaster occuring each year.even if we stop destroying environment,there are no way to restore our planet.if we continue destroying our environment,we can imagined that people will completely destroy earth.
