定语从句when和in which的区别

　　关于定语从句when和in which的区别大家了解过多少呢？可能很多人都不是很清楚，下面就是小编分享的定语从句when和in which的区别介绍，一起来看一下吧。

　　which在定语从句中只作主语，宾语，表语，修饰物

　　when，where在定语从句中只作状语，分别作地点状语和时间状语。

　　如定语从句中缺少句子成份，即，主，宾或表语缺其中任意一项，先行词又是表物的名词或代词，定语从句的关系词就用which

　　如定语从句中不缺少句子成份，即，主，宾或表齐全，如先行词为表地点的名词或代词，定语从句就用where，如先行词是表时间的名词或代词，定语从句就用when引导。

　　如果是表示地点的词，则要用where（前提：没有介词）

　　如果是表示时间的，就要用when

　　如果是表示原因的，如reason 就用why

　　在一定程度上，IN WHICH与WHERE是相等的。他们修饰 的先行词是表地点的

　　例如:The house where I live is beautibul.

　　=The house in which I live is beautibul.

　　但是当下面两种情况时就不相等了。

　　1、若IN提前，只能用WHICH，就不能用WHERE。

　　例如;The house in( )I live is beautibul.

　　句中的空就不能填WHERE。

　　或者:The house ( ) I live in is beautibul.

　　句中的空也不能填WHERE，因为后面有介词IN呀。WHERE是副词，不能跟介词。

　　2、若这个表地点的先行词是人不能到达的，就不能用WHERE。

　　例如:先行词是在墙里的某个东西，那么就只能用IN+WHICH，而不能用 WHERE。

　　拓展：

　　in which的定语从句

　　1.in which可以等于when，也可以等于where，但不会等于why.

　　关键是看定语从句中缺少时间状语还是地点状语.

　　2.例如：

　　1）I'll never forget these days in/during which I stayed with you.

　　= I'll never forget these days when I stayed with you.

　　我永远不会忘记我和你待在一起的`日子.

　　其中：in/during which I stayed with you = when I stayed with you

　　= I stayed with you in/during which = I stayed with you in/during these days

　　2）This is the city in which I stayed last year.

　　= This is the city where I stayed last year.

　　这就是那个去年我待的地方.

　　其中：where I stayed last year = in which I stayed last year

　　= I stayed in which last year = I stayed in the city last year.

　　3.另外，有的in which找不到合适的关系副词代替.

　　如：I dislike the way in which you treat me.

　　我不喜欢你对待我的方式.

　　其中：in which you treat me = you treat me in which

　　= you treat me in the way

　　4.for which = why

　　如：Can you tell me the reason why you were late?

　　= Can you tell me the reason for which you were late?

　　你能告诉我你迟到的原因吗?

　　其中：why you were late = for which you were late

　　= you were late for which = you were late for the reason
