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.
