Question

He is the only one of the students who has been invited to the English Evening.这句话有错吗？错在哪

先行词被the only,the very,the same等修饰时，后面只能用that.

Answer 1

先行词被the only, the very，the last, the just, the same 等修饰时，不管先行词指人还是指事物，引导词都用that。例如：
You’ve the only person that I met here. 你是我在这儿遇见的唯一的一个人。
This is the very shirt that I am looking for. 这正是我一直在寻找的衬衫。

所以，你的这个句子应该是：
He is the only one of the students that has been invited to the English Evening.

Answer 2

这个句子没错。当先行词被 the only ,the very 修饰时。如果被修饰词不是人而是物必需用that,而不用which.但当先行词为人时。多数用who.

Answer 3

没有错啊。至于你后面说的那个，我倒是没听说过。

Answer 4

你好。应该是
He is the only one of the students THAT has been invited to the English Evening.

---------但是，在现今的英语中，就你的句子来说， that / who的界限没有那么讲究了。连英语民族都很少考虑它们的界限了。

Answer 5

应该用have
