(定语从句)
• 在选择引导定语从句的关系代词时，有如下要点： 1 由于关系代词在主句与从句间既起到联系作用，有在从 句中充当一个成分，因此， 要正确判断关系代词在从 句中的功能，如作主语还是宾语等。 2 当先行词指人时，关系代词可用who（做主语，宾语）， that（做主语，宾语），whom（作宾语），whose（作 定语） 3 当先行词指物时，关系代词可用that（做主语，宾语）， which（做主语，宾语） 4 再定语从句中，作宾语的关系代词长可省略，但在介词 后面的关系代词不能省略。指人时，介词后只用，指物 时，介词后只用。 5 在非限制性定语从句中，指人时，只用who，指物时， 只用which。
1. The story that you read is “The Rescue”. 2. And there she saw a wall of water that was quickly advancing towaClause （定语从句）
Which house is mine?
My house
房顶是棕色的房子是我的。 The house whose roof is brown is mine.
The Attributive Clause
A clause is a part of a sentence. The Attributive Clause tells us which person or thing(or what kind of person or thing) the speaker means. e.g. The woman who lives next door is a teacher.

限制性定语从句和非限制性定语从句：

在非限制性定语从句中，指人时，只用who， 指物时，只用which。
• She looked at Jeff, who was waving his arms. • Football, which is a very interesting game, is loved by most people in the world.
