雅思语法点：定语从句和关系代词的使用规则
只能用which的情况
非限制性定语从句
例句1：This is the city, which I call my hometown.
非限制性定语从句不直接限定先行词，而是对先行词进行附加说明
使用which时，从句与主句之间通常用逗号隔开
例句2：She bought a new car, which she had been wanting for years.
介词+which（阅读常见）
例句：He comes from a small town, to which he often returns during holidays.
此结构中，which不能被that替代
介词通常放在关系代词which之前，修饰先行词
指代整个主句
例句：She failed the exam, which surprised everyone.
which指代整个先行句
用来补充说明或评论
只能用who的情况
先行词those指代人时（写作常见）
例句：Those who would like to leave the room, please do so quietly.
当先行词为those时，通常使用who引导定语从句
先行词为人称/人称代词的时候
例句：The man who lives next door is very friendly.
who指代先行词the man or he/she等代词
只能用that的情况
当先行词被形容词最高级修饰时（口语常见）
例句：This is the most exciting moment that I will never forget.
形容词最高级后接that引导定语从句
that用于限定先行词，强调最高级的比较范围
例句：This is the best restaurant that I have ever been to.
that引导的定语从句限定最高级修饰的先行词
先行词为不定代词anything, something, everything, nothing, all时（口语常见）
例句：My teacher is very proud with all (that) I did.
all作为先行词时，使用that引导定语从句
that在口语中有时可以省略
例句：There is nothing (that) I can do.
nothing作为先行词，that引导定语从句
that在口语中可以省略，但保留时更正式
例句：Is there anything (that) you dislike about your hometown?
anything作为先行词，that引导定语从句
例句：There is something （that） I need to tell you about.
something作为先行词，that引导定语从句
指代有生命但不是人的名词
出自剑桥6考官范文
例句：First of all, eggs are produced by the moth and it takes ten days for each egg to become a silkworm larva that feeds on mulberry leaves.
that引导定语从句，指代非人类的有生命体
that在定语从句中作主语，指代silkworm larva
定语从句补充说明先行词silkworm larva的特征或行为
在the only, the same, it is等表达之后
例句：This is the only book that I have read on the subject.
例句：He used the same method that I did.
例句：It is the decision that matters most.
That和Which均可使用的情况
限制性定语从句
例句：The book that/which you gave me is fascinating.
that和which均可用于引导限定性从句
that在口语中使用更多
That和Who均可使用的情况
there be句子中先行词指人，使用who或that
例句：There are many people who I find familiar.
例句：There are many people that I find familiar.
there be句子中先行词指物或抽象概念，使用that
例句：There are something that I need to tell you.
其他注意事项
非限制性定语从句只能使用which
例句：The car, which I bought last year, is red.
非限制性定语从句去掉不影响主句含义
which引导的从句前后，通常用逗号隔开
省略“that”
例句：The car (that) I bought is read.
例句：The film (that) we watched was amazing.
限制性定语从句，that有时可以被省略
