3、st, last, any, only, few, mush, no, some, very等词修饰，关系代词常用that,不用 which, who ，或 whom 。例如：(3) 非限制性定语从句中，不能用关系代词that,作宾语用的关系代词也不能省略。例如：There are about seven million people taking part in the election, most of whom are well educated.(4) which 还有一种特殊用法，它可以引导从句修饰前面的整个主句，代替主句所表示的整体概念或部分概念。在这种从句中， which 可以作

16、whenC. howD. where1-5CCBCD6-10ABADA解析：1. 【陷阱】容易误选A 或B，将A 、 B中的which和it误认为是其后句子的主语。【分析】最佳答案是C， around which were high mountains是一个由" 介词 +which"引出的非限制性定语从句，而在该从句中， 主语是，around which是表语，所以句子谓语应用复数，而不是用单数2.【陷阱】容易误选B ，认为around是介词，选which用以代替前面的名词hospital，在此用作介词around学习必备欢迎下载的宾语。【分析】最佳答案为C。以上语法分析并

17、不算错，但问题是，照此分析，此句的意思即为：有没有这样一个医院，我在它的附近可以买药治我的手伤？这样的语境显然有点不合情理，因为人们通常是在医院里面治伤，而不是在医院附近治伤。此题选C 的理由是：句中的around不是介词，而是副词，意为" 在附近 " ；其后的where引导定语从句用以修饰其前的地点名词hospital，句意为：附近有没有一家医院，我可以去治我的手伤？3. 【陷阱】容易误选 A，认为此处应填一个形式主语。【分析】最佳答案是B 。as引导的是一个非限制性定语从句。比较下面一题：_ is known to everybody that the moon tra

18、vels round the earth once every month.A. It B. As C. That D. What此题答案选A ，it 为形式主语，真正的主语是后面的that从句4. 【陷阱】此题容易误选 A，许多同学一看到题干中的such，再联系到选项中的that ，便认为这是考查such . that .句式。况且，这样理解意思也还通顺。【分析】最佳答案为C，不是 A ，因为在 such . that .（如此 .以至 . ）结构中， that引导的是结果状语从句，并且that 在从句中不充当句子成分，若在上句填入such . that .，句末的动词 like缺宾语。选

19、C 的理由如下： as用作关系代词， 用以引导定语从句， 修饰其前的名词 boy ，同时 as 在定语从句中用作动词like 的宾语，句意为 " 所有老师都喜欢的一位好男孩 " 。有的同学可能还会问，假若选A ，能否将其后的 that视为引导定语从句的关系代词呢？不能，因为当先行词受到such 的修饰时，其后的定语从句应用关系代词as 来引导，而不用 that. 比较下面一题，答案为A ，因为 like后有自己的宾语him ：David is such a good boy _ all the teachers like him.A. that B. who C. as D

20、. whom5. 【陷阱】容易误选C，用 them代指 the buses.【分析】最佳答案是D 。 most of which were already full为非限制性定语从句，修饰the buses6. 【陷阱】容易误选B，用 them代指 students.【分析】最佳答案是A ，many of whom gained great success in their own field为非限制性定语从句。假若在many of.的前面加上连词 and ，则选答案 B 。7. 【陷阱】容易误选 A，认为这是非限制性定语从句。【分析】最佳答案是B，这不是非限制性定语从句，而是一个独立主格结构

21、，因为空格后的动词invited并不是一个完整的谓语，而是一个过去分词。当然，假若在invited前加上助动词were ，则是一个非限制性定语从句，答案便应选 A.8. 【陷阱】容易误选 B ，认为这是非限制性定语从句。【分析】最佳答案是A. 与上面一题相似，their parents seated together joking不是非限制性定语从句，而是一个独立主格结构，因为空格后的动词seated不是谓语，而是一个过去分词，因为seat作动词用时，是及物动词。比较以下相似题：（1） On Sundays there were a lot of children playing in the

22、 park, _ parents were seated together joking.A. theirB. whoseC. whichD. that选 B.whose parents were seated together joking为非限制性定语从句，因为其后有完整的谓语were seated.（2） On Sundays there were a lot of children playing in the park, and _ parents were seated togetherjoking.学习必备欢迎下载A. theirB. whoseC. whichD. that选

23、A. 因为句中有并列连词and，整个句子为并列句。（3） On Sundays there were a lot of children playing in the park, _ parents sitting together joking.A. theirB. whoseC. whichD. that选 A.their parents sitting together joking为独立主格结构。（4） On Sundays there were a lot of children playing in the park, _ parents sat together joking.A. theirB. whoseC. whichD. that选 B.whose parents sat together
