(成都)
A．who B．which C．whomA【点拨】考查的是定语从句的关系词。根据句意“我喜欢在青少年中受欢迎的作家”。可知本句的先行词the writers指人，关系代词用who，故选A。典例 2—In a text message，88 means Bye-bye.
—And another example is F2F________stands for
face to face. (湖北黄冈)
A．that B．who
C．whom D．itA【点拨】考查的是定语从句的关系词。根据句意“——
在短信中， 88的意思是再见。——另一个例子是F2F代
表面对面。”可知先行词F2F指物，用关系代词that。
故选A。典例 3—Which is your new neighbour, Liu Hua？
—The man________ T-shirt is red.(山东泰安)
A．that B．who
C．which D．whoseD【点拨】句意：——刘华，哪一位是你的新邻居？——T
恤衫是红色的那个男人。在定语从句中，that，who和
which是关系代词，在定语从句中作主语、宾语或者表
语。而whose作定语，分析句子结构可知，这里的定语
从句中缺少定语，修饰名词T-shirt，故选D。考向【易错点】 that和which都可以指物，that和who都可以用来指人，但在下列情况下，只能用that引导，不能用who或which引导：
(1)当先行词是all，little，much，none，
everything，anything，nothing等词时。
eg：Is there anything that I can do for you?
我能为你做些什么吗？(2)当先行词前面有the only，the very，the last等修饰时。(当先行词是人时，也可用关系代词who，whom引导)
eg：She is the very thief that the policeman is
looking for.
她就是警察正在寻找的那个小偷。
(3)当有序数词或形容词的最高级修饰先行词时。
eg：The first thing that we should do is to finish our
homework.
我们首先要做的事情是完成作业。(4)当先行词既有人又有物时。
eg：We were deeply impressed by the teachers and
schools that we visited.我们访问过的老师和
学校给我们留下了深刻的印象。典例 1I still remember the college and the teachers ________ I visited in London years ago. (安徽)
A．what B．who
C．that D．which C【点拨】考查定语从句的关系词的用法。空格后的句子是
一个定语从句，用来修饰先行词the college and the teachers，
既包括人又包括物，所以关系词只能用that，而不能用
which，所以选择C。典例 2Being blind is something ________ most people can’t imagine. (杭州)
A．who B．what
C．that D．whomC【点拨】本题考查定语从句的关系词。先行词是something，
关系代词用that。故选C。考向三下列情况下不能用that。
(1)关系代词前有介词。
eg：This is the house in which Jiao Yulu once
lived.这是焦裕禄曾经住过的房子。
(2)先行词为that时。
eg：What’s that which you are holding in your
arms？你怀里抱着的那个是什么？魔法记忆 that和which引导定语从句的用法：
that，which可互换，下列情况须照办。that情况比较多，先来对你说一说：不定代词这一伙，全用that准没错。先行词前被限制，千万不要用which，要用which别着急，介词提前莫忘记。 一、单项选择
1．(中考·哈尔滨) Everyone has his aim in life.
However，you can’t get fat on one mouthful. Start
with the easiest thing ________ you can control.
A．who B．that C．which【点拨】考查定语从句。题意“每个人生活都有目标。然而，一口吃不成胖子。从你能控制的最容易的事情做起。”thing前有最高级修饰，故用that。 B2．The first thing ________ my brother is going to do this
afternoon is to write a letter.
A．which B．that
C．why D．whoB【点拨】考查定语从句中that的用法。当先行词前有
序数词来修饰时，引导词必须用that，故选B。3．(中考·内江) —The TV play You Who Come from the
Stars is popular recently.
—Yes. It is the only program ________ I watched this
month.
A．who B．that
C．which D．whenB【点拨】考查定语从句中that的用法。在定语从句中有序数词、形容词的最高级、the only等词来修饰先行词的时候，引导词要用that。故选B。4．(中考·临沂) After Mandela was free (自由的) in
1990，he chose to shake hands with the people ________
wanted to kill him.
A．whose B．which
C．/ D．whoD【点拨】考查定语从句的用法。题意“1990年曼德拉获得自由后，他选择了和那些想要杀死他的人握手。”先行词为the people，而且关系词在从句中作主语，用who引导。 5．(新疆) — What kind of movies do you like?
—I like movies ________ can cheer me up.
A．who B．what
C．how D．thatD【点拨】结构分析法。语境“—I like movies ________ can cheer me up.”是一个主从复合句，从句为定语从句。先行词为movies，
是物，关系代词应为that或which，故选D。6．(中考·杭州) Being blind is something ________ most
people can’t imagine.
A．who B．what
C．that D．whomC【点拨】考查定语从句。可用分析句子结构法。 something为
先行词，且关系词在定语从句中充当宾语，故选C。 7．(黄石) Confucius was a famous philosopher(哲学家)
________has influenced the world greatly.
A．whose B．whom
C．which D．whoD【点拨】结构分析法。定语从句先行词为philosopher,指人，且在从句中作主语，应用who/ that，故选D。 8. The boy________mother is a worker was hurt in the
accident.
A．who B．whom
C．whose D．which【点拨】此题易错选A或B。关系词在从句中作定语，应用whose。故选C。C9．(咸宁) In China，those ________ were born in
the Year of Sheep are said to be creative and sensitive.
A．which B．what C．whom D．who
10．That is one of the most interesting books ________ are
sold in the bookstore.
A．that B．which C．who D．whereDA【点拨】此题易错选B。若先行词前有最高级修饰时，
关系词用that。故选A。 二、把下列句子合并成一句话

Recently I made a survey① about the use of the electronic dictionary. My classmates think that the electronic dictionary is useful and convenient. It can help them to save time② when they look up③ the words. My parents think the electronic dictionary is easy to carry and that most families can afford it. But my English teacher doesn't think we should use it，because he thinks its explanations for the words are too simple. I think the electronic dictionary will make us lazy④ and that we shouldn’t use it.
Yours，
