3. Be correct 主谓不一致，人称与动词不符。例如： 　　 My sister go to the cinema at least once a wee k. (误) 　　 My sister goes to the cinema at least once a w eek. (正)

动词时态、语态的误用，前后不一致。例如： 　　 I was walking along the road, and there are n ot so many cars on the street. (误) 　　 I was walking along the road and there were n ot so many vehicles on the street. (正)

　及物动词与不及物动词的误用。例如： 　　 The traffic accident was taken place at the jun ction of two highways. (误) 　　 The traffic accident took place at the junction  of two highways. (正) 　　发生是一个主动的过程，没有什么事是被发生 的，所以不能用was taken place 。

情态动词的误用。例如： 　　They should spent much time. (误) 　　They should spend much time. (正) 　　情态动词后面常常跟动词原形，所以spend要 用原型。

名词可数与不可数的错误。例如： 　　 In modern society, people are under various pres sures(误) 　　 In modern society, people are under various kind s of pressure. (正) 　　pressure是一种无形的但是有很多种类的事物， 所以不能直接在后面加复数s，但是要形容他多，各种 各样后面加一个种类kinds of 就正确表达出了复数形 式。

动宾搭配不当。 　　 We must pay attention to it and make solutio ns to the problem. (误) 　　 We must pay attention and find a solution to t he problem. (正)
