定语从句和名词性从句

考点一关系代词引导的定语从句

1. whose是一个表示所属关系的词，在定语从句中作定语，of which可以代替whose指物，词序一般是名词+ of which或of which +名词。of whom可以代替whose指人，词序是名词 + of whom。

2. which，that所代替的先行词是表示事物的名词或代词，在从句中可作主语、宾语等。

先行词既有人又有物时，关系代词用that; which代指前面整个句子内容。

语等。

近千人在这一社区居住，他们当中很多都是从农村老家来城市寻求更好的日子的。

考点二介词提前了的定语从句

1. 与定语从句中的动词构成搭配。

2. 与定语从句所修饰的先行词构成搭配。

耐心是一种品质。没有了耐心，你不能做好工作。

3. of+which/whom表示所属关系。(表所属关系也可用whose)

考点三关系副词引导的定语从句

1 .关系副词在定语从句中作状语，when指时间，where指地点，why指原因，在定语从句

中分别作时间状语、地点状语和原因状语。

2. 先行词是时间名词或地点名词时，如果在从句中不作状语，则不能用when或where引导

定语从句，而要用which/that。

Is this the reas on( that /which)he gave us for the delay of the project?

这是他给出工程推迟的原因吗？

考点四先行词为point, situation, case等的定语从句

point, situation , case, activity等，从表面上看它们不是表地点的，但却表示类似地点的意义，

因此它们作先行词时，如果引导词在从句中作状语，那么这个引导词要用where ;如果不作

状语，则用关系代词that/which。

考点五主语从句

主语从句在主句中作主语，位于主句谓语动词之前，但多数情况下由it作形式主语，而把真正的主语放在句子的后面，其句型结构为：lt+ be+ n./adj. + that/whether/why/whe n +从句。

2. 同位语从句与定语从句的区别：
