第一、可数名词不能单独使用，前面需要加上a/an/the/this/that/my/his/your等限定词，否则就用复数。

　　例如：Government should take measure to solve problem.

　　[改]Governments should take measures to solve problems.

　　第二、动词的有效使用

　　(1)英语动词原形不能直接作主语

　　例如：Reduce the use of private cars can improve the air quality effectively.

　　[改]Reducing the use of private cars can improve the air quality effectively.

　　(2)英语动词被动，别忘了后面加-ed或者-d

　　例如：Greater efficiency in water use is need to meet the growing demands of a changing world.

　　[改错]Greater efficiency in water use is needed to meet the growing demands of a changing world.

　　(3)一定要注意主谓一致

　　例如：The problems that are created by environmental contamination is very hard to solve.

　　[改]The problems that are created by environmental contamination are very hard to solve.

　　(4)只有情态动词可以加动词原形

　　例如：A great number of people are like playing basketball.

　　[改]A great number of people like playing basketball.

　　(5)议论文里很少会用过去时

　　例如：In present-day society, cultures were becoming very similar.

　　[改]In present-day society, cultures are becoming very similar.

　　第三、修饰要准确：形容词修饰名词，副词修饰形容词或者动词。

　　例如：Intelligent students should not be treated different by their teachers.

　　[改] Intelligent students should not be treated differently by their teachers.

　　第四、介词搭配

　　例如：Countries should pay attention on the disadvantages globalisation.

　　[改]Countries should pay attention to the disadvantages globalisation.

　　第五、代词距离名词比较远时就要看它的单复数

　　例如：Some people do not protect the environment himself.

　　[改]Some people do not protect the environment themselves.

　　第六、逗号不能单独连接并列句，必须加连接词。

　　例如：Some people think that use should be limited, others argue that the opposite is true.

　　[改]Some people think that use should be limited, but others argue that the opposite is true.

　　第七、there be 句型后面的名词再加动词时不要用原形。

　　例如There are a great many students believe the main purpose of education should be to afford them pleasure and enjoyment.

　　[改]There are a great many students believing the main purpose of education should be to afford them pleasure and enjoyment.
