从句常见考点：（定从，状从，名从（主语从句、宾语从句，表语从句））小编分三篇依次大家一起学习。

定语从句考点： （一） 用关系代词还是关系副词 关系代词 who 人 主、宾、表 whom 人 宾 which 物 主、宾、表 that 人和物 主、宾、表 as 物 主、宾

关系形容词 Whose= of whom/of which 人和物的 定语 Whose与of which /whom的区别 of which/whom 时应在名词前加上定冠词 the或其他限定词，也就是说如果名词前有限定词就只能用 of which/whom 。如果名词前没有限定词，就用 whose。

关系副词 When=at/in/on/during…which Where=at/in/to…which Why=for which 注意：关系词所做的成分关键是由从句中的动词来决定 2012.22 This is the place where we work.(vi). This is the place. We work in the place. This is the place which we visited.(vt)

（二） 关系代词和关系副词的特殊情况 1．指物时只用 that，不用which 的情况： 1) 当先行词为 all, much, little, few, none, something, anything, everything, nothing 等不定代词时。 2)先行词被序数词或形容词的最高级或the last, the only ,the very等表强调的词等修饰。 3).在疑问词 who, what, which 开头的句子中。（避免歧意） Who is the girl that is talking with Mr.Brown？ 4). 当先行词既指人又指物时。 We are talking about the people and countries that we have visited.

2. 只能用 which 不能用 that 的情况。 1). 引导非限定性定语从句修饰某物或整个句子。 e.g. Bruce went towards the fire, which was still smoking. Tom came back late, which made his parents very angry. 2).在介词后面:介词+which (先行词是物) The world in which we live is made of matter. 注意:若介词在从句中而没有直接在关系词后,可以用which 或that. 例如: The world that we live in is made of matter.

（三）非限制性定语从句 非限制性定语从句不能用that引导，一般用引导词which/as/who,非限制性定语从句既可以修饰主句的部分内容，也可修饰主句的全部内容。
