each of them knows what the others are doing.这里的knows为什么加s
she is intersting to talk to 这里的talk 后面把to去掉为什么不对,
to hear him talk in that manner,you would think he is a foreigner。talk in 这里的in去掉行吗 to hear 改成 hearing行吗 为什么吗
和 he was amusing to be with。with是不是省略了什么 把with去掉对吗为什么
each of them knows what the others are doing.这里的knows为什么加s
因为each表单数.
如果是all的话,则为all of them know...
再问: they each know what the other thinks。为什么加s。
再答: 因为the other的出现情况是一共有两个个体.one... the other... 所以句中的the other是一个个体,为单数.
