Unit 5 Nelson Mandel -a modern hero grammar学案

知识点一：关系代词引导的定语从句 常用关系代词的用法如下：

关系代词 who whom that which whose as 修饰的先行词 人 人 人或物 物 人或物 人或物 所作成分 主语、宾语 宾语 主语、宾语、表语 主语、宾语 定语 主语、宾语、表语 The foreigner who visited our school yesterday is from Canada. 昨天来我们学校参观的那个外国人来自加拿大。 They planted some trees that/which didn't need much water. 他们种了一些不需要浇太多水的树木。 1.关系代词that与which的用法区别 (1)只用that引导的定语从句

that在定语从句中可以指人也可以指物，在定语从句中作主语或宾语，可以代替who, whom, which等。下列情况只用that而不用which引导定语从句。

①当先行词是不定代词all, much, little, something, everything, anything, nothing, none, the one时

Do you have anything that you want to say for yourself? 你还有想要为你自己说的事情吗？ You should hand in all that you have. 你应该上交你拥有的一切。

②当先行词前面被the only, the very(恰恰，正好), any, few, little, no, all等词修饰时

The only thing that we can do is give you some money. 我们唯一能做的事情是给你一些钱。 ③当先行词是形容词最高级或先行词的前面有形容词最高级修饰时

This is the best that has been used against pollution. 这是用来抵制污染最好的(方法)。 This is the most interesting film that I've ever seen. 这是我看过的最有趣的电影。 ④当先行词是序数词或它前面有序数词修饰时

What is the first American film that you have seen? 你看过的第一部美国电影是什么？

⑤当先行词既有人又有物时

Do you know the things and persons that they are talking about？你知道他们正在谈论的事和人吗？

⑥当主句的主语是疑问词who或which时

Which is the bike that you lost? 哪一辆自行车是你丢的？ Who is the boy that won the gold medal? 获得金牌的男孩是谁？ ⑦当先行词在主句中作表语，而关系代词也在从句中作表语时

Shanghai is no longer the city that it used to be. 上海不再是以前的那座城市了。 (2)用which而不用that引导的定语从句 ①which可引导非限制性定语从句，that则不能

He had failed in the maths exam, which made his father very angry. 他没通过数学考试，这令他父亲很生气。

②在介词提前的定语从句中，只用which而不用that引导 This is the place in which Lu Xun used to live. 这是鲁迅曾住过的地方。

例题：(2011·山东，32)The old town has narrow streets and small houses that/which are built close to each other.

解析 本题考查定语从句。句意：这古老的城镇拥有狭窄的街道和一些小房子，这些房子都靠得很近。本题为定语从句，且从句中缺少主语，用that/which引导。 2.关系代词who，whom和whose的用法 (1)关系代词who，whom先行词指人。 who是主格，在从句中作主语，不可省略； whom/that在定语从句中作宾语时，可以省略；

whose是属格，先行词既可指人，也可指物。在定语从句中用作定语，不可省略。 The man who was here yesterday is a painter. (who在从句中作主语) 昨天在这里的那个人是画家。

I know the man whom you mean. (whom在从句中用作宾语，可省略) 我认识你指的那个人。 A child whose parents are dead is called an orphan. (whose在从句中用作定语，不可省略) 失去父母的孩子叫孤儿。

I'd like a room whose window looks out over the sea. 我想要一个窗户面朝大海的房间。

＝I'd like a room, of which the window looks out over the sea.

＝I'd like a room, the window of which looks out over the sea.

例题：(陕西卷)The old temple whose roof was damaged in the storm is now under repair.

解析 该题中先行词为temple，将其代入后面的从句中可知temple作定语，故选whose。 3.关系代词as引导的定语从句

关系代词as既可以引导限制性定语从句，也可以引导非限制性定语从句，as在从句中作主语、宾语或表语。

引导限制性定语从句常用于下列句式：

We have found such materials as are used in their factory. 我们已经找到了像他们工厂里用的那种材料。(as作主语)

These houses are sold at such a low price as people expected. (as作宾语) 这些房子以人们所期望的那样的低价出售了。 He is not the same man as he was. 他和过去不同了。(as作表语)

辨析：such...as...引导的定语从句与such... that. ..引导的状语从句的区别： ①He is such a clever boy as everyone likes. 他是一个人人都喜欢的聪明男孩。

②He is such a clever boy that everyone likes him. 他是个如此聪明的男孩以至于每个人都喜欢他。

第一个句子包含了一个定语从句，因为从句中缺成分；而第二句的从句不缺任何成分，是状语从句。

(2)as表示“正如，正像”

此时，as从句中常用know, expect, happen, point out, plan, suggest等单词或短语。 He came back home late，as we expected. 正如我们所料，他回家晚了。 As is pointed out, this is a grammar problem. 正如所指出的，这是个语法问题。

例题：The new policy only covers such people as have made great contributions to our country during the war.

解析 句意：这项新政策只涉及那些在战争中为祖国做出重大贡献的人们。根据句意，判断

先行词为people，又因先行词由such修饰，故用as。 知识点二：关系副词引导的定语从句

1.当先行词在定语从句中作状语时，要用关系副词，表时间用when，表地点用where，表原因用why引导

He will always remember the day when his father returned from America. 他将永远记得他父亲从美国回来的那一天。

The factory where his father works is the largest one in this city. 他父亲工作的那个工厂是这个城市最大的工厂。 I don't know the reason why he was absent today. 我不知道他今天为什么没来。

2.介词＋关系代词＝ where/when/why/how when＝表时间的介词(in，at, during)＋which where＝表地点的介词(in，at，on, under) ＋ which why＝表原因的介词(如for) ＋which how＝表方式的介词(如in)＋which 3.关于关系副词where

高考对于where的考查趋于复杂，从先行词为明显的“地点”转向模糊化的“地点”。实际上，where的外延已发生变化，当先行词是表示某人/物的situation或某事发展的stage时都可用where这个关系副词。

They have reached the point where they have to separate with each other. 他们已经到了彼此必须分手的地步。 4.关系代词和关系副词的区别

关系代词在定语从句中作主语、宾语或表语，而关系副词在定语从句中作状语。因此在选择关系词时，最重要的是分析一下定语从句中的成分。

比较： Do you still remember the days that/which we spent in Qingdao? 你还记得我们一起在青岛度过的日子吗？

Do you still remember the days when we spent the summer holidays in Qingdao? 你还记得我们在青岛过暑假的日子吗？

注意：关系代词或关系副词的选用，关键是看先行词与从句中动词的关系：先行词是否作从句中动词的宾语或主语；将先行词带入从句中是否需要添加介词。
