很多考生在雅思写作考试中拿不到自己的目标分数，而且在这部分丢分比较严重，为了帮助大家更高提分，下面我们来看看雅思写作丢分为什么，这些细节可能正在备考的你也存在，一起来看看吧!
1. 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. His profession is a teacher.
2. 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 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 is harmful to children’s mental health.
以上为雅思写作丢分原因分析，了解了到底是那些细节问题导致我们在雅思考试当中屡屡失分，大家应该知道接下来怎么做了。
