有几个英语选择题不太懂 帮我选下呵呵
1.the bank is reported in the local newspaper __in broad yesterday
a.to be robbed b.robbed.c.to have been robbed d.having been robbed
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
3.A new technique ___out ,the yield increases by 20%
a.having working b.having been worked c.has worked d,had been worked
我会追加分数的呵呵 3中为什么用现在时的被动语态呢，和increase by 之间的关系可以解释下吗
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.
第一题绝对选c
c
b
1 d
2 d
3 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。
