calm sb./ calm sb.down
他们有区别没有?
有一个题：
Your friend seems to be upset.You should try to _______.
A.calm down him B.calm him C.clam him down D.clam them down
为什么不能选B.
calm也可以用作及物，calm sb.阿
牛津上也有这种用法
答
同意楼上的
答
calm down 是固定词组
答
calm down是习惯用法,作为动词是calm和down连在一起用才完整.
答
固定搭配～～～～～～～～～～～～～～
calm...down是一个短语的固定搭配，而且calm是不及物的，前面的主语是单数，故后面也要跟单数人称。
所以只能选calm him down。
