定语从句知识点讲解

定语从句知识点讲解

一、知识点梳理

在复合句中，修饰名词或代词的从句叫做定语从句。其中被修饰的名词或代词称为先行词，引导定语从句的引导词分为三类，分别为关系代词、关系副词、介词+关系代词。引导词位于先行词和定语从句之间，起着连接主从句、指代先行词和在句子中作成分的三重作用。

引导词：关系代词: that：可指人亦可指物；作主语或宾语

which：指物；作主语或宾语

who：指人；作主语或宾语

whom：指人；作宾语

whose：可指人亦可指物；作定语

关系副词：when：作时间状语

where：作地点状语

why：作原因状语

介词+关系代词:in/of/from/to/with/on/at+ which/ whom

二、引导词使用技巧

1.如果从句中缺少成分，在关系代词中选择

2. 如果从句中不缺少成分，在关系副词中选择

1. 找到从句划括号（引导词起，主句的第二个动词止）

2. 根据成分选连词一看指人还是物

二看介词在何处

三看句中作何用

四看是否属特殊 that/which

who/that

as/which

such …as/that

三、定语从句四大考点

1.限制性与非限制性定语从句★

2.关系代词与关系副词的选择

3.介词+关系代词结构中关系代词的选择(重难点)

4.分割式定语从句（先行词与定语从句被用作定语或状语及主语谓语而分开）

四、英语五大句式

1.主语+谓语：谓语为不及物动词，不需加宾语（动作承受者）直接

与主语（动作发出者）构成句子。

2.主语+谓语+宾语：除主语外的其他成分由及物动词或‘不及物动

词+宾语’结构构成，并构成完整句子。

3.主语+谓语+宾语+宾语：除主语外的其他部分由‘谓语+双宾语’

的结构构成。

4.主语+谓语+宾语+宾补：除主语外的其他部分由‘谓语+宾语+宾

补’的结构构成。

5.主语+系动词+表语：除主语外的其他部分由‘系动词+表语’的

结构构成。

在看从句中缺少何种成分时要依据以上五大句式的构成判断，一般缺少的为主语和宾语（宾补），这时要选择关系代词，如不缺少成分，这时要选择关系副词或“介词+关系代词”结构。

五、注意事项

1.定语从句中无what

2.关系代词中which既可指一件事也可以指一件物品

3.“介词+关系代词”结构中没有介词加who或that，which和whom 在此结构中经常使用。

4.从句中谓语动词为不及物动词时，引导词用“介词+关系代词”结构。从句中谓语动词为系动词且句子成分完整时，关系代词前面的介词需与先行词建立联系。

5. 关系代词在从句中作宾语时可省略。

6.that、why不引导非限制性定语从句
