学员经常在英语写作当中会犯一些语法的错误，这些错误会直接导致成绩的高低，如何避免这些错误呢？今天小编通过环球雅思为大家整理了一些资料，希望对大家有所帮助。
In the other room.
Over there.
在英语口语中，你可能会用到这些短语，但是因为它们毕竟不是完整的英语句子，所以在书面语言中，我们一般不会使用。
由于缺乏独立分句的从属子句导致的句子残缺很常见。记住，从属连词引出了从属子句。也就是说，如果你用一些词语来引出从句，例如because，though，if等等，就必须要有一个独立分句来使句子完整。我们在考试中，使用why来提出问题时，经常会犯这样的错误。
例如，下面这个句子：
Because Tom is the boss.
Since he left work early without permission.
We might answer the question:"Why did he lose his job?"
但是，这些句子都是不完整的。
正确用法应该是：He lost his job because Tom is the boss.
He lost his job since he left work early without permission.
其他关于从属子句的残缺句还包括下面内容：
Even though he needs help.If they study enough.
As they had invested in the company.
*种是漏掉了一个词——通常是连接词——用于连接非独立子句和独立子句。
The students did well on the test they didn't study very much.学生们考得很好他们没有下多少功夫。
Anna needs a new car she spent the weekend visiting car dealerships.安娜想买辆新车她整个周末都在约见代理商。
*句话要么应该加上一个连词but，要么加上yet，或者一个从属连词although,even though或though来连接前后两句。
The students did well,yet they didn't study very much.学生们考得很好，但他们并没有下多少功夫。
Anna spent the weekend visiting car dealerships since she needs a new car.因为想买辆新车，安娜整个周末都在约见代理商。
另一种句子不连贯发生在使用太多从句的时候。常常是由于and一词导致。We went to the store and bought some fruit,and we went to the mall to get some clothes,and we had lunch at McDonald's,and we visited some friends.我们去商店买了一些水果，去购物商城买了一些衣服，在麦当劳吃的午饭，又见了一些朋友。我们应该避免使用and来连接一大串的从句。一般来说，从句不要超过三个，以确保句子的连贯性。
例一：Tom lives in Los Angeles.
而不是Tom,he lives in Lost Angeles.。
例二：The students come from Vietnam.
而不是The students they come from Vietnam.
例如：
They fly to visit their parents in Toronto last week.上周他们坐飞机去看望父母。
Alex bought a new car and drives it to her home in Los Angeles.亚历克斯买了一辆新车，并把它开进了洛杉矶的家。
误：He hopes finding a new job.
正：He hopes to find a new job.
误：Peter avoided to invest in the project.
正：Peter avoided investing in the project.
误：She enjoys watching TV,play tennis,and cook.
正：She enjoys watching TV,playing tennis,and cooking.
误：I've lived in Italy,working in Germany and study in New York.
正：I've lived in Italy,worked in Germany,and studied in New York.
误：We'll visit you when we will come next week.
正：We'll visit you when we come next week.
误：She cooked dinner after he was arriving.
正：She cooked dinner after he arrived.他到了之后，她才开始煮饭。
