1、 第 1 页 共 12 页 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 whom which, as所有格 whom, of whom, whose which, of which, whose注意：关系代词 that 不能引导非限定性定语从
2、句。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
3、of which, whom 等结构时e.g. Youve 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 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 when I 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 tha
4、t 引导，关系代词做宾语时也不能省略。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：第 2 页 共 12 页 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。 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, wh
5、ich, whom, whose, as 和关系副词 when, where, why 引导。that 不引导非限制性定语从句。例如： We will fly to Xian 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
6、。 非限制性定语从句中值得注意的几个问题 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。例如： My new car, which I paid several thousand dollars for, isnt running 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 before 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
7、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, 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 Sundays, which he doesnt like. As we expected, he gave a wonderful performance. Mike is late, as is often the case. I never heard such stories as he told
8、. She knew he felt just the same as she 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：第 3 页 共 12 页 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 which
9、He is not such a fool as he looks.Dont read such books as you cant understand. 非限制性定语从句中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。They won the game, as we had expected.They won the game, which we hadnt expected.As is well known, he is a famous film star
10、 in the 1980s.关系代词 as 引导的定语从句和 such 连用，这时的 as 相当于 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 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。例中作 looks 的表语，在例和中
11、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： She gave me such a surprise that I couldnt 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
12、 same kind of clothes as her sister usually does. 引导非限制性定语从句例如： She was 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
13、 your father worked when he was young.此句没有先行词，where 引导的是表语从句，where 相当于“the place where”，解释第 4 页 共 12 页 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) Lets do it when we are free.此句中没有先行词，when 引导的是状语从句。2) Lets do it next month, when we are f
14、ree.这里 when 引导的是定语从句，先行词是 next month。又如：1) Put it where it was. where 引导的是地点状语从句，无先行词。2) Put it in the drawer where I keep documents. where 引导的是定语从句。（三）定语从句和强调句例 1) - Where did you interview the composer?- It was in the hotel _ he 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
15、中提出的问题。而应该选 A. where，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）定语从句和并列句例1) There are 45 students 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)
16、 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，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 English, doesnt he? 他喜欢英语，不是吗？ He doesnt like En
17、glish, does he? 他不喜欢英语，是吗？第 5 页 共 12 页 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1. We can still be friends, cant we?2. He doesnt like ice cream, does he?2. 陈述句中的主语是名词，反意疑问句中用相应的代词来代替陈述句中的主语。1）当主语是 someone, somebody, anybody, anyone, everybody, everyone, nobody, no one等不定代词时，
18、 反意疑问句中的代词用they 或者 he.2）当主语是 this, that, something, nothing, anything, 不定式，动名词，或从句时，反意疑问句中的代词用 it 1. His father cant name the plant, can he?2. Everyone has advised you not to go on a diet, havent they/hasnt he?3. This is a lovely clock, isnt it?4. Something is shining, isnt it?5. To swim in such col
19、d water is crazy, isnt it?6. What he did really scared me, didnt it?7. Shopping isnt what you want to do, is it?3. 陈述句中动词是情态动词时，一般用情态动词+代词的形式。情态动词 must 用法如下：1）作“禁止”讲时，用 must2）作“必须”讲时，用 mustnt / neednt3）作“肯定”讲时，根据动作发生的时间，选用不同的时态。1. He dare not cross the street alone, dare he?2. We neednt finish it to
20、day, need/must we?3. Students mustnt be late, must they?4. He must be in his room now, isnt he?5. They must have come back, havent they?6. You must have got the letter when you were in the office, didnt you?4. 陈述句中用了表示否定意思的 neither, none, nobody, nothing, few, little, never, hardly, seldom 等词后，反意疑问句
21、用肯定形式。但陈述句中否定意义前缀或后缀的词，不影响反意疑问句的形式。 1. Neither of you will have coffee, will you?2. She seldom argues with others, does she?3. No one has found my CD, have they?4. Its unfair, isnt it?5. They are hopeless, arent they?5. 在祈使句后的反意疑问句中， 一般用will you，但在 Lets 开头的祈使句后，一般用 shall we。1. Post a letter for me,
22、will you?2. Dont tell him about it, will you?3. Lets go, shall we?4. Let him go, will you?6. 在主从复合句中，一般与主句的谓语动词一致，但在主句主语是第一人称，并且谓语部分为 think, believe, imagine, suppose 等时，疑问句一般与从句的谓语一致。1. They told me it was not true, didnt they?2. I believe he can make it, cant he?3. We dont believe we were defeated
23、, were we?7. 反意疑问句的回答方式是根据事实情况回答，而不受提问方式影响。1. We havent been informed, have we?Yes, we have. （不，我们接到通知了。 ）No, we havent. （对，还没有。 ）（二）常见句型的反意疑问句 1当陈述部分是 there be 存在句型时，反意疑问句的主语也用 there。 e.g. There was nothing in the room, was there? 房间里什么也没有，是吗？2感叹句的反意疑问句，其谓语要求用否定句。 第 6 页 共 12 页 e.g. What a beautiful
24、 day, isnt it? 多好的天气啊，不是吗？3祈使句后面的反意疑问句问题 A) 祈使句是否定形式，反意疑问句用 will you。 e.g. Dont forget to post the letter, will you? 请别忘了寄信。B) 祈使句是肯定形式，反意疑问句用肯定、否定均可。 e.g. Please help us, will you/wont you? 请帮帮我们，好吗？C) Let 开头的祈使句要注意： 1.

25、er, shall we? 我们一起去，好吗?2. Let us 在意义上一般不包含谈话的对方在内，表示请求对方允许做某事的含义，let 有 allow 的意思。附加疑问部分用 will you。 e.g. Let us go swimming together, shall we? 我们一起去游泳好吗?3. Let me 开头表示请求，反意疑问句用 will you，或用 may I。 e.g. Let me carry the box for you, may I? 我帮你搬箱子好吗？（三）复合句的反意疑问句 1当陈述部分是一个（带 that 引导宾语从句的）主从复合句时，反意疑问句的主谓
26、要和主句的主谓保持对应关系。但是，当陈述部分的主语是：I suppose, I think, I believe, I imagine, I expect 等结构时，反意疑问句的主语和谓语要和从句的主语，谓语保持一致关系。而且要注意到否定的转移问题。 e.g. I think she is right, isnt she? 我认为她是对的，是吗？2当陈述部分是 Im sure that,；we are sure；Im afraid that；We are sure that；I feel sure that 等后面跟宾语从句时，反意疑问句与后面的宾语从句一致。 e.g. Im afraid i
27、t is going to rain, isnt it? 恐怕要下雨了，不是吗？ （四）关于情态动词的反意疑问句 1陈述部分中有 have 一词，且表示 “所有”含义时，反意疑问句部分既可用have 也可用 do。 e.g. You have a bike, havent you/dont you? 你有一辆自行车，不是吗？2陈述部分中有 have to，反意疑问句部分用 do。 e.g. He had to go to work when he was very young, didnt he?他年轻的时候不得不出去工作，不是吗？3. 含有 ought to 的反意疑问句，陈述部分是肯定的，
