我知道介词介动名词,可为什么介词后面跟一个名词再跟一个动词时,动词仍变成动名词呢?
例如:
1.Despite adequate notice being given there were still many applicants disappointed.
2.Most families are dependent on two salaries coming into the home,with women now constituting almost half the country’s workforce.
这个很简单就能理解了,你知道介词后面跟名词
Despite adequate notice being given disappointed there were still many applicants disappointed
这句话缩句之后就是:Despite notice...而being given 这部分是修饰notice的.如果直接写Despite notice are being given...那么这里的depsite充当的是连词,而就不是介词了.你想让这句话跟在介词后面,就必须把这整个句子都变成一种名词的形式.而“notice being given " 就是" notice are being given"的名词形式.
相同的还有:Would you mind my sitting here 这里的 my sitting 就是 I sit 的名词形式,因为mind后面要加一个名词,所以就不能直接使用这个句子的原型.
再例如:Her being late made the teacher angry.这里的her being late 就是 She was late的名词形式.但是这里要用这个句子充当主语,就不能直接把这句子的原型写上去,要改编成名词形式(还有一种改编方法是用That来引导:That she was late made the teacher angry )
介词也是和上面两个例子一样的道理
