定语从句复习学案

1、定语从句（三）非限制性定语从句非限制性定语从句起补充附带说明的作用，缺少它也不会影响全句的理解，译为汉语时常常不译作定语，而根据句意翻译为相应的其他形式的从句。它与主语的关系不像限定性定语从句的关系那样密切。 在非限定性定语从句的前面往往有逗号隔开，如果把非限定性定语从句放在句子中间，其前后都要用逗号与主句隔开。1. 引导非限定性定语从句的关系代词如下表所示：指代对象指代人指代物主格who宾语whomwhich, as所有格whom, of whom, whosewhich, of which, whose注意：关系代词that不能引导非限定性定语从句。引导非限定性定语从句的关系副词主要有wh

2、en, 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 garde n, 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

3、.g. You've made many mistakes, most of which were due to your careless ness.3. 限制性定语从句与非限制性定语从句的区别:类别语法意义及特征例句限制性定 语从句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。The accident happened at the time whe n 1 left.非限制性 定语从句对先行词作附加的说明，与主句的关系不十分 密切，较松散。从句和主句之间用逗号分开， 相当于一个插入语，不能用 that引导，关系代 词做宾

4、语时也不能省略。His mother, whom he loved deeply, died ten years ago.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：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 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。 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。 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 w

5、hen, where, why弓I导。that不引导非限制性定语从句。例如： We will fly to Xi 'n first, where 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。 My wife, who is a doctor, is working abroad this year.我的妻子是位医生，她今年在国外工作。 As is known to all, ice is water in its solid state.众所周知，冰是水的固态。非限制性定语从句中值得注意的几个问题在which引导

6、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。例如： My new car, which I paid several thousand dollars for, isn'trunning well.先行词是car He said that he had never seen her before, which was not true .先行词是 he had never seen her beforewhich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

7、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, the same等连用。（见第一讲中as引导的定语从句）例如： He has to work on Sun days, which he does n ' like. As we expected, he gave a wonderful performanee. Mike is late, as is often the case. I never heard such stories as he told. She knew he felt just the same as she

8、 did. 在从句中作宾语的关系代词which, who, whom 一般不省略。例如： Jeanne was her old friend, from whom she borrowed a necklace. He built a telescope, through which he could study the skies.4. as与which的区别:定语从 句区别例句限制性 定语从 句中名词前有such和the same修饰时，关系代 词用as不能用whichHe is not such a fool as he looks.Don' tread such books a

9、s you can ' un dersta nd.非限制 性定语 从句中as和which都可以指代前面整个主句。女口果有“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。They won the game, as we had expected.They won the game, which we hadn ' expected.As is well known, he is a famous film star in the 1980s.tt关系代词as引导的定语从句 和such连用，这时的 as相

10、当于 who, which。有时such和as连在一起例如： Wendy is not such a fool as she looks Such cars as I saw were too expensive to me. We had hoped to give you a chanee such as nobody else ever had.注意：这种用法和 suchthat的区别在suchas中，as是关系代词，它在从句中充当成分。例中作looks的表语，在例和中分别作saw和had的宾语。而在suchthat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，

11、只起语法上的连接作用。例如： She gave me such a surprise that I couldn 'say anything at that moment. His idea was such a good one that we all agreed to use it.和same连用例如： You must show my friend the same respect as you show me. She wears the same kind of clothes as her sister usually does.引导非限制性定语从句例如： She was

12、 the one I met at the party, as you know. As was natural, she married Robin.5.定语从句和其它从句的区分很多高三的同学在解题时发现，有时难以区分定语从句，表语从句，时间、地点状语从句和强调句。解决这一问题的关键在于牢记： 定语从句一定有先行词 定语从句的关系代词和关系副词在从句中一定充当成分。我们来看具体的从句的比较：(一) 定语从句和表语从句例 1) This is where your father worked whe n he was young.此句没有先行词，where引导的是表语从句，where相当于“

13、the place where”，解释为“的地方”。2) This is the shop where my brother once worked.此句中where引导的是定语从句，先行词是：the shop。(二) 定语从句和状语从句例 1) Let 'do it whe n we are free.此句中没有先行词，when引导的是状语从句。2) Let 'do it n ext mon th, whe n we are free.这里whe n引导的是定语从句，先行词是next mo nth。又如：1) Put it where it was.where引导的是地点状语

14、从句，无先行词。2) Put it in the drawer where I keep docume nts.where引导的是定语从句。(三) 定语从句和强调句例 1) Where did you in terview the composer?It was in the hotelhe stayed.A. where B. that此句看上去很像强调句型，很多同学因而错选 B。但选B后意思是：他住在宾馆里。 不能回答上文中提出的问题。而应该选A，句子的意思是：是在他住的宾馆。 所以,正确地解这一题除了要求对定语从句和强调句型有很好的掌握以外，还考查了对题 目所给出的语境的理解。（四）定语

15、从句和并列句 例 1） There are 45 stude nts in our class, of whom two fifths are girls.of whom/which +分数/百分数/ both / all / none / some / many 这样的结构常出现在定语 从句中，尤其是在较正式的文体中。更常见的是：分数/百分数/ both / all+of whom/which ,此句是定语从句。2） There are 45 students in our class, and two fifths of them are girls. 此句中的第二分句由并列连词and引起

16、，因此，不是定语从句。反意疑问句一、基本用法与结构反意疑问句由“陈述句+简单疑问句”两部分组成，第一部分提出一种看法， 第二部分用来质疑或表示证实。陈述部分与疑问部分的动词时态和动词性质应保 持一致，而且肯定和否定形式彼此相反，即陈述部分为肯定式时，疑问部分用否定式，陈述部分为否定式时，疑问部分用肯定式：He likes En glish, does n他喜喜欢?英语，不是吗？He doesn ' t like English, does h他不喜欢英语，是吗？二、反意疑问句的用法：（一）具体用法整理如下:用法例句1.肯定陈述句后反意疑问句用否定形式，否 定陈述句后反意疑问句用肯定形式
