Question

一道英语题谢谢

The problem they raised at the meeting is worth _____.
A.discussing B.being discussed
答案是A,为什么不是被动语态呢?
B也是be worth doing sth,只是变为了被动,为什么不行?

Answer 1

be worth doing sth 是固定用法，没有被动形式，主动表被动
名子的主语与动名词在逻辑上有动宾关系，因此这个动名词应该是及物的（如上述例句）或具有及物性质的短语动词（如下述例句）。
The broadcast programme is worth listening to .这条广播节目值得一听。
The picture is worth taking good care of .那幅画值得好好保存

The book is worth reading . 这本书值得一读。
比较：The book is worthy of being read .
The book is worthy to read.

Answer 2

因为 worth doing sth. 固定的 主动被动都是这样

Answer 3

be worth doing sth.这个是固定用法。
