作者句法知识很棒，适当增加从句的使用，会取得更不错的成绩；文中词汇表达多样请继续保持，也能较熟练地使用部分学术词汇，但请认真检查词汇的拼写；文章结构不够严谨，应增加过程性词汇的使用。
It is well-known that human activities have negative effect on plants and animal species.Such as in beijing,the moment the winter comes,the sky becomes grey and a large number of dirt drifting in the air.At this time,if people go out without mouth-mufles,it will be miserable for them to breathe freely. In the meantime the thing occurs in tianjing and other big cities. Some people think that it is too late to do anything about this problem.In their opinion,it is impossible that we want to recover an extinct species,not to mention ecological balance. Other people believe that effective measures can be taken to improve this situation. In their view,we may protect endangered animals and plants as well as the existing spieces through raising the people's enviromental awareness . As far as I'm concerned,it is indeed true that we can't recover an extinct species.However we are able to protect the existing spieces as well as solve the pesent prolerms.We may do the things as follows,forest planting and improve environmental pollution.In the area near huanghe river, in the past sevral decades.people have planted many trees and grass in the desert.Now we have seen the beautiful scenery and the local habitants live a happy life.This proves that we completely can find the effective measures to deal with all the kinds of pollution.For example ,if we reduce the pollution caused by the motor vehicles,the air will get better.In brief,Olny we take action, everyting will be better.
