They found the lecture hard( )
A.to be understood b.to understand
C.for understanding d.to have been understood
为什么不选A，应该是演讲被明白，用被动吧
答案就是B.
1. To learn English is difficult.
=It's difficult to learn English.
=English is difficult to learn.
最后一种句型是固定的用主动表示被动的结构,总结为:
sb/sth be+adj+to+V原(+介词).
其中sb/sth刚好是动词V原的宾语,如果该动词为不及物动词,则需要补上合适介词.
再如: The job is hard to do.=It is hard to do the job.
He is easy to work with.=It's easy to work with him.
2. 再来看看本句.
They found the lecture hard to understand.
=They found (that) the lecture was hard to understand.
后面这句宾语从句就刚好是上面提到的固定的用主动表示被动的句型.
而如果是They found the lecture hard to be understood.
=They found (that) the lecture was hard to be understood.
这两种都是不符合英语表达习惯的错误句型.

be ... to do
这个do已经含有被动的意思，是人去do
不需要再加被动语态

句子其实是这样的：
they found the lecture is hard to understand 的不定式短语变形。
变成they found the lecture hard to understand.
they found the lecture is hard to understand 的不定式短语变形。
变成they found the lecture hard to understand.
