__,________,________和 whose, 另外,as 也可充当_____代词。关系代词 在定语从句中充当主语、宾语、表语和定语。关系副词有:______, ______和_____。在定语从句 中充当状语。 二、关系代词的用法 (一)基本用法 根据先行词的不同,和在从句中所充当的成分不同,选用不同的关系代词。 如下表: 关系词 who 先行词 _____ 从句成分 主语,宾 语 例句 Do you know the man _____ is talking with your mother?

定语从句学案 注意:关系代词在定语从句中充当宾语时可以省略,充当主语时则不能。 (见上例③④) (二)关系代词 that 代替 which 的一些情况 which, that 在代替物时,一般可以通用。 但在有些情况下,只用 that。 ⑴ 先行词是最高级__________或它的前面有________________修饰时。 ① This is the best ______ has been used against pollution. ② English is the most difficult subject _____ you will learn during these years. ⑵ 先行词是_____________,或它前面有一个______________时。 ① This is the last place (that) I want to visit. ② It is the first American movie of this kind that I’ve ever seen. ⑶ 先行词是 all, much, little, ____________, everything, anything, _____________, none 等代词时。 ① You should hand in all that you have. ② We haven’t got much that we can offer you. ⑷ 先行词前面有 the only, the ________, any, few, little, no, ______, much, every 等修饰时。 ① The only thing that we can do is to give you some money. ② The little money (that) he had was stolen.

(五)与 whose 有关的问题 ⑴ whose 是代词的所有格,它既可以代人也可以代物。 ① I saw a woman whose bag was stolen. ② Please show me the book whose cover is red. ⑵ 当 whose 表示物与物的所有格关系时,亦可用 of which 的形式。 ① The building whose roof you can see from here is a new restaurant. → The building, the roof ___ _______ you can see from here, is a new restaurant.或 → The building, _______ the roof you can see from here is a new restaurant. 三、介词前提的问题 关系代词在定语从句中充当介词宾语时,介词可以前提至关系代词前。 Have you seen the pen (which) I wrote the note with just now? →Have you seen the pen with which I wrote the note just now? 但是,要注意的是: ⑴ 介词前提后,先行词是人或物,关系代词分别只能用_____和______,而不再用 that 或 who。
第 2 页 共 40 页

定语从句学案 ⑵ 介词前提后,关系代词不再能省略。 ⑶ 有些含有介词的短语动词中的介词不能前提,如:look for, look after, take care of 等。 例如:(T or F) ① ( ( ):Who is the old man to that you were talking to? ):Who is the old man to whom you were talking ? 或 Who is the old man (that/ whom) you

were talking to? ② ( ):These are the sheep of which the boy took care. ( ):These are the sheep (which/that) the boy took care of. 四、关系代词在从句中作主语时,从句中的主谓一致 关系代词在定语从句中作主语时,从句的谓语动词在人称和数上应与先行词一致。 ① Who is the guy that is reading over there? ② The number of people that are going to the exhibition is expected to be over 25,000. ③ All that needs to be done has been done. ④ He is one of the students who use computer a lot for study. ⑤ Timmy is the only one of the pupils that has failed the exam. 例③中的 all 意为“一切” ,作单数。例⑤中没通过考试的学生事实上只有一人,因此谓语动词也 用单数。 二、语法知识拓展 (一)选择适当的关系代词 that, which, who, whom 或 whose,把下列句子补充完整。 1.

一、 “介词+关系代词”结构
第 6 页 共 40 页

定语从句学案 1. 可代替 when, where, why, that 等关系词 e.g. There is no reason _____ ________ (why) we shouldn’t be friends. 2. 介词后面的关系词不能省略。 e.g. Here is the money _____ ______ to buy a piano. 3. that 前不能有介词。 4. 某些在从句中充当时间, 地点或原因状语的 “介词+关系词” 结构可以跟关系副词 when 和 where 互换。 e.g. This is the house ___ which I lived two years ago. =This is the house where I lived two years ago. Do you remember the day ____ which you joined our club? Do you remember the day when you joined our club? 二、关系副词的用法: 关系词 关 系 副 词 when where why 先行词 时间 地点 原因 从句成分 时间状语 地点状语 原因状语 there. This is the house where I was born. I can’t imagine the reason why he turned down my offer. 例句 I will never forget the day when we met 备注 可 用 _______ 代替 可用 in which 代替 可 用 _______ 代替

(一)基本用法 关系副词起连接主句和从句的作用,又在从句中作状语,when, where 和 why 分别表示时间, 地点和原因。 1. when 在从句中作时间状语。常用 on which, in which, at which, during which 等代替。 e.g. April the first is the day when people make fun of others. =April the first is the day _____ which people make fun of others. 2. where 在从句中作地点状语。常可由 in which, on which, at which, on which 等取代。 e.g. This is the house where he lived two years ago. =This is the house ____ which he lived two years ago. 3. why why 在定语从句中作原因状语。可用 for which 代替。why 不可引导非限定性定语从句,此时 可用 for which 代替。 e.g. This is the reason why he went away. =This is the reason ______ which he went away. (二)关系副词常可用“介词+关系代词”的结构改写 这里的关系代词只限于 which 和 whom,例如 ① I will never forget the night when I met you for the first time. =I will never forget the night _____ which I met you for the first time. ② This is the house in which I lived two years ago. =This is the house _______ I lived two years ago.

定语从句学案 ③ We don’t know the reason for which he suddenly fell ill. =We don’t know the reason _____ he suddenly fell ill. 注意:并不是所有的介词+关系代词的结构都可用关系副词替代。 例如: I am very impressed by the way in which he works. 这里 in which 代表的是 in the way, 在句中作方式状语。只有当介词+关系代词结构作表示时 间、地点和原因的状语时,才能相应地用 when, where 和 why 代替。 (三)如何判断是用关系代词还是关系副词 这本质上取决于关系代词和关系副词在定语从句中充当的成分。前者充当主语、宾语、表语 或定语,后者充当状语。 试比较下面两组句子: ① This is the factory that/which produces radios. This is the factory where radios are produced. 第一句中划线部分在从句中作________,故而应选用关系代词: ② Do you remember the days _____ we spent together? Do you remember the days _____ we worked together? 第一句中关系代词在从句中作________, 而第二句中关系副词作_________. (四)一些需要特殊记忆的关系词的用法 1. I don’t like the way in which he look at people. 当先行词是 way 时,除了 in which,还可以用 that 来引导定语从句。that 还经常省略。又如: Judging from the way ______/______/_____he walked, I believe he was wounded in the leg. 2. Finally came the day when he had to leave his hometown. 当先行词为 time, moment, day 等,并在从句中作状语时,从句也可以用 that 引导,that 也常 省略。又如: ① It was the first time (that) we had stayed up so late. ② The moment (that/when) he sent the mail, John realized what a mistake he had made. ③ She was the only girl I went steady with during the four years (that /when) I was at university. 四、判断关系代词与关系副词的方法: 1. 用关系代词,还是关系副词完全取决于从句中的谓语动词。及物动词后面没有宾语,就必须要 求用关系代词;而不及物动词则要求用关系副词。 判断下列句子的对错 ( ) This is the mountain village where I visited last year. ( ) I will never forget the days when I spent in the countryside. ( ) This is the mountain village (which) I visited last year. ( ) I'll never forget the days (which) I spent in the countryside. 2. 准确判断先行词在定语从句中的成分(主、谓、宾、定、状),也就能正确选择出关系代词/关系 副词。 例 1. Is this museum ___ you visited a few days age? A. where B. that C. on which D. the one 例 2. Is this the museum ____ the exhibition was held. A. where B. that C. on which

定语从句学案 关系词的选择依据在从句中所做的成分,先行词在从句中做主、定、宾语时,选择关系代词 (who, whom, that, which, whose); 先行词在从句中做状语时, 应选择关系副词 ( where 地点状语, when 时间状语,why 原因状语) 。 五、语法知识拓展 (一)选择适当的关系代词或关系副词把下列句子补充完整。 1. His father died in the year _________ he was born. 2. He is unlikely to find the place _________ he lived forty years ago. 3. Do you remember the day _________ you joined our club? 4.

非限制性定语从句 指代人 who __________ of whom, whose 指代物 _________ which, as of which, whose

1. 引导非限定性定语从句的关系代词如下表所示:

注意:①关系代词 that 不能引导非限定性定语从句。 ②引导非限定性定语从句的关系副词主要有 when, where。不可用 why。 2. 运用非限定性定语从句的情况: (1)关系代词指代整个主句内容 e.g. Our new house has a lovely garden, which makes us very happy. (2)当先行词是专有名词或物主代词和指示代词所修饰时,其后的定语从句通常是非限制性的。 例如: Charles Smith, who was my former teacher, retired last year. (3)当出现 some, many, few, a few, little, much, most, two of which, whom 等结构时 e.g. You’ve made many mistakes, most of which were due to your carelessness, 3. 限制性定语从句与非限制性定语从句的区别: 类别 限制性定语 从句 语法意义及特征 对先行词起修饰限制作用,如果去掉,主句意思 就不完整明确, 这种从句与主句的关系十分密切, 写时不用逗号分开。 对先行词作附加的说明,与主句的关系不十分密 非限制性定 切,较松散。从句和主句之间用逗号分开,相当 语从句 于一个插入语,不能用 that 引导,关系代词做宾 语时也不能省略。 非限制性定语从句主要在以下方面不同于限制性定语从句: ⑴ 非限制性定语从句和主句的关系不十分密切, 它不是对先行词进行修饰或确定, 只是对先行词 作些附加的说明。专有名词通常被非限制性定语从句所修饰。例如:地名,人名,国家名等。 ⑵ 非限制性定语从句不是先行词必不可少的修饰语,因此如果去掉从句,主句的意思仍然清楚。 ⑶ 从句和主句之间往往用逗号分开,翻译时复合句通常译成两句话。 ⑷ 与限制性定语从句一样,非限制性定语从句也可用关系代词 who, which, whom, whose, as 和关 系副词 when, where,引导。that ,why 不引导非限制性定语从句。 例如: ① We will fly to Xi’an first, _______ we plan to stay for a couple of days. 我们将先飞往西安,在那里我们打算停留两天。 ② My wife, ______ is a doctor, is working abroad this year. 我的妻子是位医生,她今年在国外工作。 ③ ______ is known to all, ice is water in its solid state.

㈢ 非限制性定语从句中值得注意的几个问题 ⑴ 在 which 引导的非限制性定语从句,先行词可以是一个名词或代词,也可以是句子的一部分, 甚至整个句子。 ① My new car, which I paid several thousand dollars for, isn’t running well. 先行词是_____ ② He said that he had never seen her before, which was not true. 先行词是_______________________________ ⑵ which 和 as 引导的非限制性定语从句比较 which 和 as 都可引导非限制性定语从句,并且先行词都可以是一句句子,但 which 通常指代上文 提到的情况,而 as 则可以指代上文或下文。 as 在这类句子中经常有“正如”的意思。另外,as 还经常与 such…as, the same…as 等连用。 例如: ① He has to work on Sundays, which he doesn’t like. ② As we expected, he gave a wonderful performance. ③ Mike is late, as is often the case. ④ I never heard such stories _____ he told. ⑤ She knew he felt just the same _____ she did. ⑶ 在从句中作宾语的关系代词 which, who, whom 一般不省略。 例如: ① Jeanne was her old friend, from whom she borrowed a necklace. ② He built a telescope, through which he could study the skies. 4. as 与 which 的区别: 定语从 句 限制性 定语从 句中 非限制 性定语 从句中 区别 名词前有 as,such 和 the same 修饰时,关系 代词用_______ ,不能用 which as 和 which 都可以指代前面整个主句。如果 有“正如,象”的含义,并可以放在主句前, 也可以放在后面,那么用 as;而 which 引导 的从句只能放主句后, 并无“正如”的意思。 例句 He is not such a fool as he looks. Don’t read such books as you can’t understand. They won the game, as we had expected. They won the game, which we hadn’t expected. As is well known, he is a famous film star in the 1980s.

关系代词 as 引导的定语从句 ⑴和 such 连用,这时的 as 相当于 who, which。有时 such 和 as 连在一起。例如: ① Wendy is not such a fool as she looks. ② Such cars as I saw were too expensive to me. ③ We had hoped to give you a chance such as nobody else ever had. 注意:这种用法和 such … that …的区别 在 such … as …中,as 是关系代词,它在从句中充当成分。例①中作 looks 的表语,在例②和③中 分别作 saw 和 had 的宾语。而在 such … that …中 that 引导的结果状语从句,解释为“以至于” 。 that 不充当任何成分,只起语法上的连接作用。 例如:
