Question

定语从句中如果先行词是anyone,关系代词用that还是who

Answer 1

要用that
附只能用that的情况：1. 当先行词为 anything，everything，nothing 等不定代词时，只能使用"that”。 例：Is there anything that I can do for you? 我能给你做点什么吗? 2. 当先行词为 all, any, much, many 词时，只能使用"that”。 例：Tom told her mother all that had happened. 汤姆把事情的全部情况告诉了他的妈妈。 3. 当先行词是形容词最高级或被形容词最高级修饰时，只能使用"that”。 例：This is the most wonderful time that I have ever had. 这是我度过的最美好的时光。 4. 当先行词是序数词修饰时，只能使用"that”。 例：He was the first person that passed the exam. 他是第一个通过考试的人。 5. 先行词被 the only，the very，the same，the last 修饰时，只能使用"that”。 例：This will be the last chance that he can get. 这将会是他得到的唯一机会。 He is the only person that can help you out. 他是唯一能帮你的人。6. 先行词里同时含有人或物时，只能使用"that”。 例：They talked of things and persons that they remembered in the school. 他们谈论他们记得的有关学校的事和人。 7. 当主句是以 who，which 开头的特殊疑问句或先行词是 who 时，只能使用"that”。 例：Which is the book that he bought from the library yesterday? 哪本是你们昨天从图书馆借的书？

Answer 2

anyone后用who，相当于whoever,当然用that也是可以的。因为用who不用that的情况一般出现在非限制性定语从句中。
必须用that不用which与物有关，与人无关。与人有关的必须用that的：先行词包含人和物时，就用that
例子：
It's not a job for anyone who is slow with numbers. 这不是一种适合任何对数字反应慢的人的工作。
《柯林斯英汉双解大词典》
=It's not a job for whoever is slow with numbers.
Anyone who leaves the room last should turn off the lights.
=Whoever leaves the room last should turn off the lights.
Anyone (that/who/whom） I know? 是我认识的人吗？
再来一个例子：
I was the only one in my office who was invited to the ball.
先行词one（指人），有了only，但引导词还是可以用who，当然，that也可。

Answer 3

回答如下：
先行词为指人的复合不定代词时，关系代词应该用who, 不能用that。只有指物的复合不定代词才用that：
Anyone who breaks the law will be punished.
There is nothing that can be done now.

Answer 4

一般用who, that不常用
先行词是指人的代词， 比如anyone, someone, those, all 等等，常用who
比如He who has been to the great wall is not a true man.

Answer 5

定语定语从句中先行词是不定代词时，引导词用that。
所以先行词是anyone,引导词用 that
