which、that 是关系代词，它在从句中代替先行词the building,
同时担任从句中的主语，也起连词的作用，把两个简单句连接 起来。
v 关系代词的使用取决于先行词，它们的关系非常密切，因为关系代词在
定语从句中代替主句中的先行词，所以它在一般情况下都跟在先行词之后， 而且它的 人称、数必须和先行词一致。

Point 2
宜用that不宜用which引导 定语从句的情况
1. 当先行词是all, little (少), few, much, any, everything, anything, nothing, none等不定代词或被这些词修饰时 2. 当先行词既包括人又包括物时 3. 当先行词被the only, the very, the last, the same 等修饰时 4. 当先行词被序数词或形容词最高级修饰时 5. 当主句是以who, which开头的特殊疑问句时

12．必须注意的问题： (1)关系词作主语时，从句中谓语的数。 (2)注意区别定语从句与强调句。 ①定语从句中关系词作从句成分，复合句。 ②强调句中it无意义，that/who不是引导词。 ③去掉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)
9．whose作关系词既指人又指物，在从句中作定语。 Do you know Mr.Smith whose story is very moving? There is a room，whose window faces the river. 10．关系代词as在从句中作主语、宾语和表语。 (1)先行词被such和the same修饰，或句型as many(much)中，从句都用 as 引导。Such books as you bought are useful. The school is just the same as it was 10 years ago. 注意：①such...that...引导结果状语从句。如：They are such lovely children that we love them much。 ②the same...that...引导定语从句。如：I want to use the same tool that you used just now.

关系词： 用来引导定语从句，为避免先行词的重复出现用来代替先 行词的词。分关系代词和关系副词。
常见关系词：that, which, who, whom, whose, when, where, why, as
先行词与关系词的联系
• 1）"先行词"与"关系词"的内在联系"先行词"与"关 系词"之间实质上是互等、互换的关系。也就是说， 关系词的作用就是将先行词所表达意义"代到"从 句中来起作用。例如：
二：先行词已有序数词或形容词的最高级或the last, the only等作定语时，例如：
This is the most impressive TV theater that has never been put on show before. 这是以前从未上演过的最有感染力的电视剧。
That is the only way that leads to your success . 那是通向你成功的唯一之路。
Do you know the man whom you just spoke to? 错误：I have no idea about the man whom wrote the article.
• 关系代词whose ：用于代替"表示人或物意义"的 先行词，在从句中作定语，往往与它所修饰的名 词一起构成一个名词短语在从句中担当成分。 Whose常表达"某人的、某物的"之意。例如：
• 2）“先行词”的意义决定“关系词”的选择“关 系词”的选择往往是由“先行词”自身表达的意 义，以及它在从句中的语法功能而决定的。例如：
• Some people who are successful language learners often fail in other fields.

• 5.the reason why(=for which)是由why或for which引导的定语从句。 而the reason that也是that引导的定语从句。that往往省略。 This is the reason why he was late. =This is the reason (that)he was late. 6.当主句中有who,which时，而定语从句中也要用到who或which 时，为了避免who…who,which…which等重叠，定语从句用that引导。 Who is the man that is standing by the door? Which of the two cows that you keep produces more milk? 7.先行词为人和物作并列成分时，定语从句用that引导。 John and his dog that were here a moment ago disappear now. 8.不论人或物在定语从句中作表语时，用that引导定语从句，而 that通常省掉。 He is no longer the man that he was. 9.“one of＋可数名词复数”引导的定语从句中,谓语动词应用复 数；而“one of＋可数名词复数”前有the，only或the only修饰，定 语从句中的谓语动词用单数。 He is one of the students who study very hard at school. He is the(only/the only) one of the students who studies very hard at school.
• 4.先行词是表示地点的名词时（country, school, room…），而关系词代替先行词在定语从句中充当地点 状语，一般用where引导定语从句。which前介词的选择是根据先 行词与介词的搭配关系而定。

Bob took down my telephone number so as/ in order not to forget it.
In order to catch up with the earliest bus, I got up at 5a.m.
②表结果：
不定式作结果状语常用在下列结构中：so…as to, such…as to, …enough to, only to(常表示意外结果或 事与愿违的结果)，too…to等。
He is said to have gone abroad. Heat is considered to be a form of energy. You are supposed to pay the bill by Friday. The book is reported to be translated into 30 languages. The patient is believed to have been saved.
I was very happy to see her yesterday.
The teacher was disappointed to see him sleeping in class.
注: 1. 不定式的否定。not +不定式 例： Tell him not to be late.
The policeman told the boys not to play in the street. 2.不定式与疑问词连用,
一、作主语(表示某一次动作；单个不定式作主 语时谓语用单数) To finish the work in ten minutes is very hard.
To lose your heart means failure.
