典型定语从句易错题详解

■The factory was built in a secret place, around ______ high mountains.

A. which was                         B. it was

C. which were                        D. 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 is                          B. it is

C. which are                        D. them are

(2) The murder happened in an old building, beside ______ the city police station.

A. which are                        B. it is

C. which is                          D. them are

(3) Next month we’ll move to a new building, next to _______ a nice restaurants where we can have Chinese food.

A. which are                        B. it is

C. which is                          D. them are

■A man with a bleeding hand hurried in and asked, “Is there a hospital around ______ I can get some medicine for my wounded hand?”

A. that                                B. which

C. where                             D. 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. It                                      B. As

C. That                                  D. 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 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。

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 increasing.

A. Which                                B. As

C. That                                  D. It

(2) ______ is mentioned above that the number of the students in senior school is increasing.

A. Which                                B. As

C. That                                   D. It
