不少同学对自己的雅思作文成绩很有把握，可是每当分数出来的时候却都是令人大跌眼镜。事实上，我们的作文可能出现了一些我们自己也不知道的语法错误。今天小编就为大家来介绍七个雅思写作中同学们最容易犯下的错误，希望大家引以为戒。

　　1. 双谓语错句

　　There be句型属于双谓语错句高发句型，因为句中的be动词已经是谓语，而句子后面的动词通常是定语从句中的成分，故不能作为主句中的谓语。

       如：Causes for this phenomenon are comprehensive but the major reasons contribute to this problem can be identified from three perspectives.应改成：

　　Causes for this phenomenon are comprehensive but the major reasons contributing/which contribute to this problem can be identified from three perspectives.

　　2. 句子不完整

　　e.g. The most popular kind of transport was by road.

　　句中主语是the most popular kind of transport，谓语动词(系动词)是was，而by road按照语法应该是方式状语，此句缺乏表语。应改成：

　　The most popular kind of transport was road.

　　又如：Many factories in order to get more profits， which made waste water and waste gas.

　　去除目的状语“in order to getmore profits”和非限制性定语从句“whichmade waste water andwaste gas”，剩下的是many factories，不能作为一个句子。根据此句想表达的意思，应改为：

　　Manyfactories in order to get more profits made waste water and wastegas.

　　3. 主系表结构使用错误

　　e.g. We are impossible to make any progress without correcting the mistakes.

　　此句的主干结构是：we are impossible“我们是不可能”，表意不对。这种表达在英语中对应的句型是：It is…for…to…，所以应该改成：

　　It is impossible for us to make any progress without correcting the mistakes.

　　类似的错误例句还有：People are very convenient to get information on the Internet.

　　4. 情态动词后的动词原形和动名词的使用出错

　　e.g.Another equally vital point to be considered is that building them may costs much money and energy.

　　这种错误可能是笔误，在雅思作文中偶尔出现不至于扣分，但是通篇都是这样的错误，那么肯定是有影响的。

　　e.g.Another point to be discussed is that more time spending on computersis harmfulto children’s mental health.

　　“花更多时间在电脑上”这个动词短语作为主语应该要用动名词形式：

　　Another point to be discussed is that spending more time on computers is harmful to children’s mental health.

　　5. 标点符号用错

　　e.g. As far as I am concerned, people should take exercise and relax themselves on a weekly basis. Because it offers great opportunities to release their stress.

　　Because引导的句子做原因状语从句，既然是从句，那么前面就不应该使用句号使其独立成句，而应该改成逗号，because首字母小写。

　　6. 词性使用错误

　　e.g. One possible solution is using the new energy to instead of the traditional energy.

　　Instead of是介词，而这里构成to do(不定式)，只能用动词。因此，可改为：

　　One possible solution is using the new energy to replace the traditional energy.

　　e.g.Nowadays， some students study many subjects in university， which leads to that they suffer great mental pressure.

　　Lead to中to是介词，后面不能直接加句子，因此可在leads to后加一名词，构成同位语从句：

　　Nowadays,some students study many subjects in university， which leads to the fact that they suffer great mental pressure. 或Nowadays， some students study many subjects in university， which makes them suffer great mental pressure.

　　7. 从句的误用和滥用

　　e.g. The reason why I assert it is necessary for government to provide better education and health care for rural areas because it can ensure all citizens to have access to them.

　　“why…rural areas”在句中作the reason的定语，固定句式“the reason why…is that…”why引导的定语从句和that引导的表语从句连用，气势磅礴，这就是所谓的高分句型。

　　e.g. In this essay， I will discuss what those， who are two kinds of people in this topic， are how to think and how to choose. 实再迂回婉转，不知所云。
