一、定语从句
1．We will never forget the firemen_______lost their lives in the forest fire in April 2019 in Liangshan, Sichuan.
A．that B．which C．where D．when
【答案】A
【解析】
【详解】
句意：我们将永远不会忘记那些在2019年4月四川凉山森林大火中丧生的消防员们。
根据句子结构可知，该空所填的连词引导的是定语从句，修饰空前的名词the firemen。分析定语从句的结构可知，从句中缺少主语，应填关系代词，先排除C和D两个关系副词。which应用于先行词是物的时候，此处是人，故排除B。that引导定语从句时，先行词可以为人，也可以为物。故选A。
2．The We Chat is an invention can help people talk to friends, share photos, ideas and feelings freely.
A．which B．who C．whose D．/
【答案】A
【解析】
试题分析：句意：微信是可以帮助人们和朋友自由地聊天，分享照片，想法和感觉。这是一个定语从句，先行词是物invention，关系词可以用which或者that，但是先行词在从句做主语，that不可以省略。故选A。
考点：考查定语从句的用法。
3．The old town has narrow streets and small houses _____are built close to
each other.
A．who B．that C．what D．They
【答案】B
【解析】
试题分析：句中先行词为small houses，在定语从句中作主语，故用关系代词that。句意：老镇有狭窄的街道，小房子建得彼此相靠近。
考点：考查定语从句的用法
4．This is the dictionary ________ Mum gave me for my birthday.
A．which B．what C．whose D．whom
【答案】A
【解析】
【详解】
句意：这是那本母亲给我作为生日礼物的字典。这里是定语从句，先行词是为物时用
which；what不能引导定语从句；先行词指人时用who；当先行词为物主代词时用whose。本题先行词为dictionary，字典是物，所以用关系词which。故选A。
5．All the children like the teachers ________ can understand them.
A．what B．which C．who D．whose
【答案】C
【解析】
【详解】
句意：所有的孩子都喜欢能理解他们的老师。
本句是一个定语从句，先行词teachers是人，而且关系词在定语从句中作主语，故用关系代词who引导此定语从句，故选C。
6．This is the most beautiful picture __________ I have ever seen.
A．that B．which C．what D．who
【答案】A
【解析】

结合句意和语境可知选A。
点睛：限制性定语从句中只能用that 引导定语从句的几种情况：
当先行词是everything, anything, nothing （something 除外）, all, none, few, little, some等不定代词时，或当先行词受every, any, all, some, no, little, few, much等词修饰时。如：
Have you set down everything that Mr Li said? There seems to be nothing that is impossible to him in the world. 注意：当先行词指人时，偶尔也可用关系代词who。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. 所有被邀请参加婚礼的
客人都是重要人物。2. 当先行词被序数词修饰时。如：The first American movie that I watched was the Titanic. 3. 当先行词被形容词最高级修饰时。如： This is the best museum that I have visited all my life. 4. 当先行词被the very, the only, the first / last等修饰时。如：She is the only person that understands me. 注意：当先行词指人时，偶尔也可以用关系代词who。如：
Wang Hua is the only person in our school who will attend the meeting. 5. 当先行词前面有who, which等疑问代词时。如：Who is the man that is standing in front of the crowd? 站在人群前
面的那个人是谁？Which is the room that Mr Wang lives in? 哪一间是王先生住的房间？
当先行词人与物时。如：Look at the man and his donkey that are walking up the street.
当先行词是reason, way（方法）等词时，关系代词常用that代替in which, for which, why, 也常可省略。如：She admired the way （that） they solved the questions.
7．Theaters may have a brighter future if they can provide a movie experience
