为什么不是D

4 No one knows whether his storyis ture ot not,( C )?

A is it B isn't it C does it D doesn't he

因为前面是用NO ONE就是没有人知道,已经是否定了,所以反意疑问名后面那个问句应该用肯定形式.

为什么不选择D,使用被动式

5 We often find the groud( C )yellow leaves after a strong wind in autumn.

A be covering with

B cover with

C covered with

D Be covered with

过去分词作定语

与其修饰的词是被动关系,相当于一个被动语态的定语从句.

为什么此被动式后跟to,不是固定搭配watch sb do sth

6The robber was watched ( A )the bank.

A to enter B to enter into C enter D entered

因为是被动式,所以应该用TO DO STH.如果是主动的,那前面的主语就不是ROBBER.就可以说成(WHO)WATCHED THE ROBBER ENTER THE BANK.

A和B有何区别

7 The seriously wounded soldier had ( B )after the operation.

A a supper B a small supper C early supper D the supper

用SMALL修饰,强调士兵手术后吃得很少.
