【参考答案】D

一、限制性与非限制性定语从句

限制性定语从句对先行词起修饰限制作用;非限制性定语

从句对先行词起补充说明作用。非限制性定语从句中,

先行词与定语从句往往有逗号隔开。非限制性定语从

句相当于并列句、状语从句等。

二、关系词的用法

(一)关系词的作用和分类

1关系词的作用有三个:

(1)连接作用:关系词引导从句,把从句和主句连接起来;

(2)替代作用:关系词在从句中替代先行词;

(3)成分作用:关系词在从句中总是充当句子成分。

2. 关系词的用法分类

关系词

先行词所指

在从句中所作成分

关系

代词

that

人/物

主、宾、表

which

主、宾、表

who

主、宾

whom

whose

人/物

as

人/物/事情

主、宾、表

关系

副词

when

时间

时间状语

where

地点

地点状语

why

原因

原因状语

关系代词的用法与分类有三点依据:

(1)根据所引导的从句的限制性和非限制性;

(2)根据所替代的先行词是指人还是指物;

(3)根据它在从句中所充当的成分——

主语、宾语、表语或定语。

 (二)关系代词that和which的用法

1限制性定语从句中,必须用关系代词that的情况

(1)当先行词是不定代词all,much,little,something,

everything,anything,nothing,none,the one时。

(2) 当先行词前面有the only,the very(恰恰,正好),

 any,few,little,no,all等词修饰时。

(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。

(4)当先行词是序数词或它前面有序数词修饰时。

(5)当先行词既有人又有物时。

(6)当主句的主语是疑问词who或which时。

(7)有两个定语从句时,其中一个关系代词宜用which,另外一个宜用that。

(8)当先行词在主句中作表语,而关系代词在从句中也作表语时。

2当先行词指事/物时,定语从句中必须用which的情况:

(1)在非限制性定语从句中,只用which,不用that。

(2)当动词短语中的介词提前时,只用which,不用that。

(三)关系代词who,whom,that和whose的用法

当先行词指人:

①关系代词在定语从句中作主语时,用who/that,不可省略;

②关系代词在定语从句中作宾语时,用whom/who/that,可以省略;

③关系代词在定语从句中作定语时,用whose,不可省略。

【拓展延伸】

【特别注意】

1. 非限制性定语从句中关系代词和关系副词的用法

(1)关系代词和关系副词在任何情况下都不能省略;

(2)who(主语),whom(宾语),which(主语,宾语)不能用that代替,也不能互相替换;

(3)在"介词+which/whom从句"结构中,介词不能移到从句的后面;

(4)when,where可用于非限制性定语从句中。

2. 在一些固定搭配的动词短语中,由于动词和介词不可分割,因此不能把介词置于关系代词之前。

This is the pen(which/that)I’m looking for.

这是我正在寻找的那支钢笔。

不可以说:This is the pen for which I’m looking.

I. 语法填空

II. 改错

1. (1)interesting→interested  【解析】考查形容词,由于此句的主语是人,而interesting的主语是物,故将interesting改为interested。

(2)that→which  【解析】考查非限制性定语从句,非限制性定语从句需要用which引导,故将that改为which。

2. (1)在picture前加the/ this  【解析】考查限定词的用法。单数可数名词前应该有限定词,根据句意可知在picture前加the或者this。

(2)they→that/which  【解析】考查定语从句。they不能引导定语从句,因为关系代词指代things,所以把they改为that或者which。

III. 单项填空

1. A  【解析】句意:我们在日常生活中遇到的小问题可能就是伟大发明的灵感。_________ we meet in our daily lives是定语从句,从句缺少宾语,先行词是problems,用that。

2. B  【解析】本句是一个非限制性定语从句,先行词是My eldest son,根据句

和空后名词确定引导词在从句中作定语,选项中只有whose作定语修饰名词。故选B。

3. C 【解析】考查主谓一致。本句是包含定语从句的复合句,先行词Great Expectations是书名,看作单数,所以定语从句的谓语也要使用单数形式;根据"strengthened"可知,"被广泛阅读和得到高度评价"发生在过去,故选C。

 6. D 【解析】本句使用关系代词which引导非限制性定语从句,其中which指代前面整个句子的内容。

7. D 【解析】分析句子结构可知,空处引导非限制性定语从句,指代的是整个主句,故可排除A、C两项。as引导非限制性定语从句时,表示"如同,正如",符合题干意思,故选D项。
