典型定语从句易错题详解■The factory was built in a secret place, around ______ high mountains.A. which wasB. it wasC. which wereD. them were【易错】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high mountains，around which 是表语，所以句子谓语应用复数were，而不是用单数was。

请做以下类例题目（答案均为C）：(1) Yesterday we visited a modern hospital, around _______ some fruit shops.A. which isB. it isC. which areD. them are(2) The murder happened in an old building, beside ______ the city police station.A. which areB. it isC. which isD. them are(3) Next month we’ll move to a new building, next to _______ a nice restaurants w here we can have Chinese food.A. which areB. it isC. which isD. them are■A man with a blee ding hand hurried in and asked, “Is there a hospital around ___ ___ I can get some medicine for my wounded hand?”A. thatB. whichC. whereD. what【易错】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 的宾语。

【分析】最佳答案为C。

以上语法分析并不算错，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？■ _____ is known to everybody, the moon travels round the earth once every month.A. ItB. AsC. ThatD. What【易错】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 travels round the earth once every mo nth.A. ItB. AsC. ThatD. 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。

再比较下面一组题，其中第(1)题选B，第(2)题选D：(1) ______ is mentioned above, the number of the students in senior school is increa sing.A. WhichB. AsC. ThatD. It(2) ______ is mentioned above that the number of the students in senior school is in creasing.A. WhichB. AsC. ThatD. It■ David is such a good boy _______ all the teachers like.A. thatB. whoC. asD. whom【易错】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a s 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. thatB. whoC. asD. whom请再做以下试题（答案选D）：It was not such a good dinner _______ she had promised us.A. likeB. thatC. whichD. as■ The buses, most of _______ were already full, were surrounded by an angry crow d.A. thatB. itC. themD. which【易错】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 buses。

类似地，以下各题也选D：(1) His house, for _______ he paid $10, 000, is now worth $50, 000.A. thatB. itC. themD. which(2) Ashdown forest, through _______ we’ll be driving, isn’t a forest any longer.A. thatB. itC. themD. which(3) This I did at nine o’clock, after _______ I sat reading the paper.A. thatB. itC. themD. which类似地，以下各题选whom，不选them：(4) George, with _______ I played tennis on Sundays, was a warm-hearted person.A. thatB. himC. themD. whom(5) Her sons, both of ______ work abroad, will come back home this summer.A. thatB. whoC. themD. whom(6) I met the fruit-pickers, several of _______ were still university students.A. thatB. whoC. themD. whom■ He had thousands of students, many of ______ gained great success in their own field.A. whomB. themC. whichD. who【易错】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。

比较以下各题(答案均选A)：(1) He asked a lot of questions, none of ______ was easy to answer.A. whichB. themC. whatD. that(2) He asked a lot of questions, and none of ______ was easy to answer.A. themB. whichC. whatD. that(3) He told me that he had two girl-friends, neither of _______ knew anything about the other.A. whomB. themC. whichD. who(4) He told me that he had two girl-friends, and neither of _______ knew anything a bout the other.A. themB. whomC. whichD. who■ He had a lot of friends, only a few of ______ invited to his wedding.A. whomB. themC. whichD. who【易错】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，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。

比较：(1) They put forward a lot of plans at the meeting, none of _______ carried out in t heir work.A. whichB. themC. whatD. that答案选B，none of them carried out in their work 是独立主格结构，其中的carried o ut 为过去分词。

(2) They put forward a lot of plans at the meeting, none of _______ were carried ou t in their work.A. whichB. themC. whatD. that答案选A，none of them were carried out in their work 是非限制性定语从句，注意与上例比较句中多了一个助动词were。
