雅思写作不能犯的语法错误

之前小编有分享很多雅思写作的技巧和方法 ，今天小编要分享的是：雅思写作不能犯的语法错误，希望可以帮到正在备考雅思写作的同学。

主语是名词性质的，不能用介词短语来充当。

note: 主语由名词性质的词来充当，具体可以是名词，代词，动名词，to do 不定式，从句等。

动词原型直接做主语

Watch  Watching TV for a long time harms children’s eyes.

动词原形不能做主语，主语一般是名词性质的成分来充当，所以一般用动名词形式，偶尔也有to do 不定式。动名词做主语当单数第三人称来理解，注意主谓一致的问题。

没有主语

To begin with, what students should do is to acquire more academic knowledge, which lies in the fact that get a lot of skills in life.

To begin with, what students should do is to acquire more academic knowledge, which lies in the fact that they can get a lot of skills in life.

这句话最后从句当中缺主语，注意，即使是从句也要保证句式的完整，缺什么补什么。

句子直接做主语

Public vehicles operate at night is a kind of waste in gasoline and electricity, which is going to be the opposite side of our initial aim.

That public vehicles operate at night is a kind of waste in gasoline and electricity, which is going to be the opposite side of our initial aim.

句子不能直接放在句首做主语，但是主语从句可以，如果写的句子是陈述句，那就可以直接在句子前面加that。

介词短语做主语

However, by improving the supervision in those pollution is an effective measure.

Without enough physical activities will result in many diseases.

Lack of physical activities will result in many diseases.
