主謂不一致，人稱與動詞不符。例如：
My sister go to the cinema at least once a week. (誤)
My sister goes to the cinema at least once a week. (正)
上面例句中，主語是My sister ，為第三人稱，所以謂語動詞應該用第三人稱單數(shù)形式goes才正確，這種主謂不一致的錯誤在寫作中是很常見的問題，稍一疏忽就會犯，考生需要更加細心才行。
句子成分殘缺不全，語句不通。例如：
We should read books may be useful to us. (誤)
We should read books which may be useful to us. (正)
這是一個定語從句的例句，其中which在從句中做的是主語，所以不能省略，一旦省略就會造成句子成分殘缺，考試中大家在寫完一句話時要記得讀一遍看看通不通順。
句子成分多余，累贅復雜。例如：
This test is end, but there is another test is waiting for you. (誤)
One test ends, but another is waiting for you. (正)
這一句的錯誤有點中式英語的味道，逐字逐句對應翻譯，there is 放在這里，累贅而又繁瑣。
動詞時態(tài)、語態(tài)的誤用，前后不一致。例如：
I was walking along the road, and there are not so many cars on the street. (誤)
I was walking along the road and there were not so many vehicles on the street. (正)
這個例句中前面是was walking ，所以后面也要用相應的過去進行時were，同一個句子里，沒有特殊情況，前后時態(tài)時要保持一致的。
We have little time to read some books which we interest. (誤)
We have little time to read some books in which we are interested. (正)
這一句也可以說是定語從句語法錯誤，be interested in是我們都知道的固定搭配，所以它后面跟賓語一定要有介詞in，所以從句引導詞要用 in which 。
詞類混淆，詞性不明。例如：
It is my point that reading must be selectively. (誤)
In my opinion, reading must be selective. (正)
這句中，be 后面是形容 reading 的意思，所以要用到一個形容詞，而selectively明顯是一個副詞。
名詞可數(shù)與不可數(shù)的錯誤。例如：
In modern society, people are under various pressures(誤)
In modern society, people are under various kinds of pressure. (正)
pressure是一種無形的但是有很多種類的事物，所以不能直接在后面加復數(shù)s，但是要形容他多，各種各樣后面加一個種類kinds of 就正確表達出了復數(shù)形式。
及物動詞與不及物動詞的誤用。例如：
The traffic accident was taken place at the junction of two highways. (誤)
The traffic accident took place at the junction of two highways. (正)
發(fā)生是一個主動的過程，沒有什么事是被發(fā)生的，所以不能用was taken place 。
情態(tài)動詞的誤用。例如：
They should spent much time. (誤)
They should spend much time. (正)
情態(tài)動詞后面常常跟動詞原形，所以spend要用原型。
動賓搭配不當。例如：
We must pay attention to it and make solutions to the problem. (誤)
We must pay attention and find a solution to the problem. (正)
There be句型的誤用。例如：
There exists some new problems such as being dishonest. (誤)
There exist/arise some new problems such as being dishonest. (正)
There be句型中動詞一般用原型，exist/arise 不需要變成第三人稱單數(shù)形式。
以上只是英語寫作中大家容易犯的一些語法錯誤，實際上在平時，我們看來，這些錯誤都很簡單，但是考試的時候由于粗心大意，越是簡單的東西越不仔細留心就越容易出錯，老師為大家總結的錯誤都是具有代表性的，希望大家好好了解上面這些錯誤，爭取自己在考試中不要重蹈覆轍，預祝大家考試順利!
