第一段最后 angel楼主是不是想写angle? 换成viewpoint更好
第二段 建议从however另起一段 However, it is also true that everyone suffers from it,for the pollution it brings. 最为这段的topic sentence 这样文章显得更为整齐具有逻辑.
Some pollutions have developed to so serious that they threaten our survival .有问题首先pollution 不可数 其次 整个句子结构很混乱. 更具楼主大概意思,将其改为, Pollution problems are increasingly endangering the survival of the human race. 然后3,4段 应该合为一段, 说得都是一个意思 第4段最后deceptive 应该为deception .n
后面的 It's a high time.......
