pollution of environment
These days we often hear that (our living conditions are getting more and more serious because of the destruction of our environment ).It is common that (many trees and animals are near extinction, and the all-important food chain has been destroyed .).
Why does such circumstance occur in spite of social protects? For one thing ,(the population of the world is increasing so rapidly that the world has been so crowded. ).For another,(the overuse of natural resources has influenced the balance of natural ecology ). What is more , since ( the industrial revolution ) ,it is natural that (a great number of factories have been springing up like mushrooms .The smoke and harmful chemicals released from factories also pollute the environment ).
To solve the problem is not easy at all ,but is worthying .We should do something such as (planting more trees , equipping cars with pollution-control devices and learning to recycling natural resources )to improve the present situation ,and i do believe everything will be better in the future .
作文的开头
一篇文章通常可分为三个部分，即开头、正文和结尾。这三个部分安排是否得体，直接影响到文章的质量。
文章的开头一般来说应尽量做到开门见山，用简单明白的叙述引出文章的话题，使读者了解文章要谈论什么，一下于引起读者的兴趣。
作文常见的开头形式大致有以下几种：
1．开门见山，揭示主题
文章一开头，就交待清楚文章的主题是什么。如“How I Spent My Vacation”(我怎样度假)的开头是：
I Spent my last vacation happily．
下面是题为"Honesty"(谈诚实)一文中的开头：
Honesty is one of the best virtues．An honest man is always trusted and respected．On the contrary, one who tells lies is regarded as a "liar"，and is looked upon by honest people．
2．交代人物、事情、时间或环境开头
