定语是什么？
基本概念：
(1) 定语从句：在主从复合句中用作定语的从句叫定语从句。
定语从句一般紧接在先行词后面。
(2) 先行词：被定语从句修饰的成份。
先行词可以为一个词，短语，或整个主句。
(3) 关系词：引导定语从句的词叫关系词，分为关系代词和关系副词。
关系词的作用：
A. 引导定语从句，连接主句和从句，相当于一个连词；
B. 必在从句中作某个句子成份
C, 指代先行词
关系词
指代人或物

【考点剖析】

2. The country is in the situation where a war will break out at any time. 国家正处在随时有可能爆发战争的局势中。

考向4： 关系副词的选择技巧：一断，二找，三放
1. 先判断句子是否是定语从句，若是， 断开主句从句部分。
2. 找先行词指什么：人，物或其他。
3. 放先行词于从句作什么成分，以判断应选关系代词或关系副词。 如果后面从句不完整，缺主语，宾语或定语时，就用关系代词。如果后面从句是完整的，不缺主语，宾语或定语，作状语时就用关系副词。
例2．【单句填空】
1. The reason __________he did it is not clear.
The reason __________he gave to the teacher is unbelievable.
2. I will never forget the day_________I met.

3.My connection with pandas goes back to my days on a TV show in the mid-1980s, 　　　　I was the first Western TV reporter. 
【答案与解析】
1.which　分析句子结构可知,空格处引导非限制性定语从句,且从句中缺少主语,故填which。
2.who　先行词是Sarah,从句中缺少主语,所以应该用who。
3.when　由句子结构可以判断空格处引导非限制性定语从句,先行词是表示时间的mid-1980s,从句中缺少状语,因此填关系副词when。

考点四：介词+关系代词which/whom
1） This is the watch (which/that) I am looking for.
2） The babies (whom/who/that)the nurse is looking after are very healthy.

【真题演练】
定语从句专练
1.I had a concert ticket for a show that I couldn't attend it.
【答案】将attend后的it去掉
【解析】
考查定语从句。句意：我有一张演出的票，我不能去看。在定语从句中that已经指代了show，所以不需要用it。故将it去掉。

【解析】
考查定语从句句意：家庭长辈，尤其是父母，应该营造一种氛围，鼓励孩子们快乐地倾诉心声。分析可知，空处引导定语从句，修饰先行词atmosphere，且关系词在从句中作地点状语，所以用where引导。故选B项。

【答案】B
【解析】
考查定语从句和介词辨析。句意：学习另外一种语言就好像跨出了一扇房门，通过它，我可以回顾并且更加清楚地明白自己的语言。分析可知，空格处引导定语从句，根据句意可知，通过这扇门，先行词door做through“通过”的宾语，指物，用冠词代词which，by表示方式，on“在……上面”不符合句意，故选B。

考查定语从句的关系词。句意：销售经理是一个职位,在这个职位上,交流能力和销售能力一样重要。分析句子可知，本句为限制性定语从句，position 为先行词，在定语从句中作地点状语，关系副词为where。故选B。

11.Communication technology has entered the 5G era,________will surely bring great changes to our life.
A. when B. what C. which D. where
【答案】C
【解析】
考查定语从句。句意：通信技术已经进入了5G时代，这必将给我们的生活带来巨大的变化。此处为非限制性定语从句修饰上文整个句子，从句中缺少主语，故应用关系代词which引导。故选C。
12.My mother is the busiest person in the family, which always has a lot of housework to do.
【答案】which→who
【解析】
考查定语从句。句意同上。此处引导非限制性定语从句，先行词my mother，指人，在定语从句中作主语，需用关系代词who引导。故将which改为who。
13.I have a pet cat, which name is Lucky. She has white hair and two big eyes.
【答案】which→whose
【解析】

【解析】
考查定语从句。句意：在音乐会两部分之间有间隙时间，那个时候观众可以买冰激凌。此处是非限定性定语从句，先行词为interval(幕间休息)，连接词在定语从句中做时间状语，应使用关系副词when引导。故选A。
15.In the dark street, they wasn’t a single person, _______ she could turn for help.
A. to whom B. whom C. to which D. which
【答案】A
【解析】
考查非限制性定语从句。句意：在黑暗的街道上，没有一个人是她可以求助的。分析可知，“_______ she could turn for help”应是之前名词“a single person”的非限制性定语从句，将先行词还原，从句应是：she could turn to a single person for help，其中，turn to sb. for help，固定短语，“向某人求助”，因此先行词在从句中作to的宾语，应用关系代词whom，从句中缺少固定短语介词“to”，可将其放置whom前，构成“介词+关系代词”结构引导从句，即to whom。故选A项。
16.We live in this society now __________ actually someone is always helping.
A. when B. where C. that D. what
【答案】B
【解析】
