Question

The children all looked in the（)after the holiday

A.black B.pink C.red D.green选哪个？

Answer 1

首先你要明白the children是主语，had played the whole day long 是定语，用来修饰the children的 如果你在这个句子中用them，那么the children和all of them 就都变成了主语。因为你看啊，这两个句子都是通的： The children were worn out. All of them were worn out. 你用哪一个当作主语，另一个都得哭，是不是？ 如果你在这个句子中使用whom, whom 在这里代指the children而且whom不能做主语，你看： all of whom were worn out 不是一个句子。在这里用whom而不是用who是因为whom做宾格用在介词后面
