that。 e.g. A plane is a machine that can fly.
考点二：连接词which的用法
Which引导非限定性定语从句，其先行词可是一个词,也可是整 个主句或主句的某一部分。
e.g. 1. She heard a terrible noise, __ B ____ brought her heart into her mouth. A. it B. which C. this D. that
②as引导非限制性定语从句。as在从句中作主语、 表语或宾语，这个定语从句是说明整个句子， 它可以放在主句之前。
四、关系代词 which和as 在定语从句中的区别：
which-从句不能放在句首，而as-从句则能；在句中 时， as 有“正如”、“就象”之意，而 which 则 没有 。
eg：
I like the same book as you do .(as作宾语) I shall do it in the same way as you did.(as作状语) I want to have such a dictionary as he has. （as作宾语）
I happened to get thiatt in the bookstore yesterday. ④将关系词移至该句句首。－－成为从句。 ⑤把从句放在先行词之后。－－完成。

3、关系词：引导定语从句的关联词就叫关系 词。
A. 把从句和主句中被修饰的先行词连接在 一起．

③强调it is / was和that / who后如果句子意思讲得通则是强调句，讲不通则不是。
It is the museum that / which we visited last year.(定语从句)It was in the hotel that we stayed last night.（强调句）（3）定语从句与同位语从句的区别。
①定语从句引导词被称为关系词，that充当主语、宾语、表语。
有时可省略。
②同位语从句引导词被叫做连词，that不能充当任何成分，不可省。
Word came that their army was defeated.(同位语)We expressed to them our wish that was the same as their.(定语)（4）关系词在从句中省略的情况。

The film brought the hours back to me _________ I was taken good care of in that faraway village.（NMET 2001）A.untilB.thatC.whenD.where解析：答案为C。
本题考查分隔定语从句的关系词的选择。
作好本题的关键是要能辨认出该定语从句的先行词the hours和关系词被介词短语to me所分隔。
定语从句的先行词是表时间的名词hours, 并且关系词在从句中用作状语，故应选择表示时间的关系副词when。
2. ___________ is known to everybody, the noon travels around the earth once every month.(NMET 2001)A.ItB.AsC.ThatD.What解析：答案为B。
本题考查as引导的非限制定语从句。
as作“正如……”解时，引导的非限制性定语从句来修饰整个句子。
当as在从句中作主语时，常用于下列短语：as is known、as is said、as is reported、as is announced等。
要注意掌握作关系代词引导定语从句的用法。
3. After living in Pairs for fifty years he returned to the small town ___________ he grew up as a child.(NMET 1996)A.whichB.whereC.thatD.when解析：答案为B。
本题考查限制性定语从句中关系词的选择。
定语从句的先行词是表示地点的名词短语the small town, 且关系词不作定语从句中的主语和宾语而作地点状语，因此定语从句必须用关系副词where引导。
要注意分清先行词在从句中充当的成分，然后选择适当的关系词。
4.The English play my students acted at the New Year’s party was a great success.A. for whichB. at whichC. in whichD. on which解析：答案为C。
考定语从句。
主句部分应是The English play at the New Year’s party was a great success.从句补全为独立句子应是my students acted in the play。
所以应选in which，其余介词不妥。
5.There were dirty marks on her trousers she had wiped her hands.A. whereB. whichC. whenD. that解析：答案为A。
本题考地点状语从句，用where引导。
