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.
