雅思写作语法致命伤1. 双谓语错句

　　Therebe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。例句中同时出现了“were”和“study”，根据上面的分析，were应该是谓语，而studyfor career应该是定语从句，因此，例句应修正改成：

　　For those under 26， there were 80% students who studied for career. 或者Forthose under 26， there were 80% students studying for career.

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

　　Causes for this phenomenon are comprehensive but the major reasonscontributing/which contribute to this problem can be identified from threeperspectives.

　　雅思写作语法致命伤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byroad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 andwaste gas.

　　去除目的状语“in order to get more profits”和非限制性定语从句“which made 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：

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

　　雅思写作语法致命伤3. 主系表结构使用错误

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

　　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 themistakes.

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

　　雅思写作语法致命伤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 maycosts 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 harmful to 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 isharmful to children’s mental health.

　　雅思写作语法致命伤5. 标点符号用错

　　e.g. As far as I am concerned， people should take exercise and relaxthemselves on a weekly basis. Because it offers great opportunities to releasetheir 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。

　　雅思写作语法致命伤6. 词性使用错误

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

　　e.g. Nowadays， some students study many subjects in university， which leadsto 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 tothe fact that they suffer great mental pressure. 或Nowadays， some students studymany subjects in university， which makes them suffer great mental pressure.

　　雅思写作语法致命伤7. 从句的误用和滥用

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

　　“why…rural areas”在句中作the reason的定语，固定句式“the reason why…isthat…”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 peoplein this topic， are how to think and how to choose. 实再迂回婉转，不知所云。

　　除了上面所列其中7类语法错误情况以外，常见的雅思写作语法错误还包括：主谓一致，时态，特殊句型(如倒装句，强调句等)使用错误以及逻辑问题等。
