1the man was sent to prison for six months,＿guilty of theft. 答案是having been found 2the bank is

Question

the bank is reported in the local newspaper＿in broad daylight yesterday.答案是to have been robbed哪位大侠帮忙解释一下它们两个之间的区别！

Answer 1

两题都是被动语态的现在完成时，区别在于第一题是现在分词having，第二题是不定式to have。
第一题：
having been found guilty of theft作原因状语。如果换成to have，就变成目的状语了，就与语境不合。
第二题：
the bank is reported in the local newspaper to have been robbed，如果转换成主动形式可能有助于理解：
The local newspaper reportes the bank to have been robbed. 这里to have been robbed作宾语补足语。
这跟ask sb to do sth的被动说法sth is asked to be done结构是一样的。

Answer 2

第二个句子是固定句型 It is/was reported that sb./sth. ....的变体句型
sb/sth. is /was reported to do/to be doing/to have done(主动 )/ to be done /to have been done (被动 ）:报道时，银行已经被抢劫了
第一句是现在分词作状语，having been found 表被动已完成，动作发生在主句动作 进监狱之前 被发现

Answer 3

having been found,是强调find guilty这个动作发生在send to prison之前,而主句与从句之间又是被动关系.
be reported to have been robbed.不定式的一般式,表示将要发生的动作.只有完成时,可以表示过去,或过去完成时. 之所以用不定式形式,是因为它作bank的宾补.即:report the bank to have been robbed.
