they all are friend 还是 they are all friend

问题描述:

they all are friend 还是 they are all friend

一般情况下见到的是they are all friends.

they are all friend

都不对.
应该是: They are all friends.[friend要用复数形式]
all在这里用作adv.副词, 副词,用在be动词后,实义动词前.

按语法来讲,应该是they are all friend。all,both等次用在be动词之后。
但有时为了强调,从这个角度来说,they all are friend也对。

They all are friends.
all they:他们中的所有人,强调人数.
they all:他们都,强调效果.
