定语从句：
一：概说
1 定义：在复合句中起定语作用的从句叫做定语从句。
（定语从句一般放在它所修饰的名词或代词——即先行词之后）
2 种类；
⑴限定性定语从句：限定性定语从句对说明句子意义来说必不可少，如果省略句子意思不
完整，有时甚至会被歪曲，限定性定语从句不用“，”和句子的其他部
分隔开。
⑵非限定性定语从句：非限定性定语从句对说明句子意义来说未必必不可少，如果省略
句子意思仍然完整，非限定性定语从句通常用“，”和句子的其他
部分隔开。
例句：①限定性定语从句：正在睡觉的那个男孩是汤姆。
The boy who is sleeping is Tom.
②非限定性定语从句：水，一种清澈透明的液体，很有用途。
Water,which is a clear liquid,has many uses.

⑴限定性定语从句不能省略，如果省略，句意不完整；

⑵限定性定语从句不用“，”把它和句子的其他部分隔开；
非限定性定语从句用“，”把它和句子的其他部分隔开。

二：用法：
一关系代词的用法
1 who→在定语从句中做主语→用来指人
例句：我喜欢那个来自美国的男孩儿。
I like the boy who is∕comes from America.
2 whom在定语从句中做宾语→用来指人
例句：①我喜欢的那个男孩儿是汤姆。
The boy whom I like is Tom.
②你正在等的那个医生现在在房间里。

3 whose在定语从句中做定语→用来指人或指物

4 which→在定语从句中做主语或宾语→用来指物
例句：①这是你想要的那本书。

②我喜欢红色的那辆车。
I like the car which is red.
5 that→在定语从句中做主语或宾语→用来指人或指物（可以用who, whom, which替换）
※ 必须用that的7种情况：
⑴先行词是all, everything, nothing, few, little等不定代词时，必须用that引导。
例句：我会告诉你我知道的一切。
I shall tell you everything that I know.
⑵当先行词被序数词或形容词最高级修饰时必须用that引导。
例句：①我不会忘记我学过的第一课。
I can’t∕won’t forget the first lesson that I learned.
②他是我见过的最可恨的人。
He is the most hateful person that I’ve seen.
⑶当先行词被all, every, little, few, no等修饰时，必须用that引导。
例句：我喜欢你给我的所有的书。
I l搜趣网ike all the books that you gave me.
⑷当先行词被the only（唯一的）；the very（恰好，正好）；the same（相同的）；the last(最后的)等修饰时，必须用that引导。
例句：你是我唯一喜欢的人。
You’re the only person that I like.
⑸当先行词既有人又有物时，必须用that引导。
例句：我不知道他们正在谈论的人和事。
I don’t know those persons and things that they are talking about.
⑹当that用做关系副词，修饰表示时间的名词时，可以代替when来引导。
例句：我不会忘记我第一次见到你的那一天。
I can’t forget the day that∕when I first met you.
⑺当句子中已有who出现时，必须用that引导。
例句：正在唱歌的那个女孩是谁？
Who is the girl what is singing?
6 as→在定语从句中做主语或宾语→用来指人或指物。
such…as… 如此像…，这样的像…，像…一样
the same…as… 相同的…，像…一样
例句：你们正在唱的那样的歌很流行。
Such songs as you’re singing are popular now.
二关系副词的用法
1 when→先行词表示时间
例句：我不能忘记在上海的那些日子。
I can’t forget those days when I was in Shanghai.
2 where→先行词表示地点
比较：where→定语从句中谓语动词为不及物动词时用。
that∕which→定语从句中谓语动词为及物动词时用。
例句：This is the place where I lived(不及物动词) last year.
This is the place which∕that(及物动词) last year.
3 why→先行词只有一个reason（原因）
例句：这就是我喜欢你的原因。
This is the reason why I like you.

两句是对的。
第一句不能用where，因为这里定语从句中少了一个主语，that代替cities作从句的主语，而where是副词，不能充当成分（主语）。
从句少宾语，及物动词用代词，也可以省略代词，不及物动词用副词。
比如：He is a nice person who we like.(who作及物动词like的宾语，此时也可以省去who)
This is the city where he works.(work是不及物动词，所以从句he works是完整的，不缺少成分，因此只能用副词where表示地点)

1.当先行词是everything, anything, nothing (something 除外), all, none, few, little, some等代词时，或当先行词受every, any, all, some, no, little, few, much等代词修饰时。如：

　　Any man that / who has a sense of duty won’t do such a thing. 任何有责任感的人都不会做这样的事。
　　All the guests that / who were invited to her wedding were important people. 所有应邀来参加她婚礼的客人都是重要人物。

　　The first place that they visited in London was the Big Ben. 在伦敦他们参观的第一个地方是大本钟。
