all them和them all哪个对

them all
all of them

them all对
例如: I can't meet them all within a day.我不可能在一天之内都会见他们。
all of them也可以，
例如：I can't meet all of them within a day.

them all 对

all them 不对
只有all of them
Well, you can't win them all.:

好啦，你不可能事事都如意。

如以下例句：
Leave them all for dead.(一首歌的名字）
依本人拙见
应该是all of them
没有all them这种说法吧！

后者
前者为all of them 较合适

them all对
all of them
