Vocabulary and Structure 1．The bank is reported in the local newspaper ______ in broad daylight yesterday.
A．being robbed
B．having been robbed
C．to have been robbed
D．robbed
….be said/reported/thought/believed to do sth.这句话的意思是：据当地地方报纸报道这家银行昨天在光天化日之下被抢劫。to have been robbed 是动词不定式的完成形式，表示动作发生在谓语动作之前。
2.Contrast may make something appear more beautiful than it is when__alone.
a.seen b.is seen c.to be seen ,d.having been seen
分词作状语，see与句子主语之间是动宾关系，应该用过去分词，所以答案为seen。
1 d
2 d
3 b
第一题绝对选c
c
b
1.c 被动完成
2.a when it is seen alone 的省略
3.b 没有连词，是单句。
