由when引导的定语从句

  英语,最早被中世纪的英国使用,并因其广阔的殖民地而成为世界使用面积最广的语言。下面是小编为大家整理的由when引导的定语从句,欢迎阅读与收藏。

  when 可以引导很多从句:

  1.宾语从句:例如 I don`t know when he left here.我不知道他上面时候离开的.此时when作连接词引导宾语从句.

  2.定语从句:例如 He left his hometown in that year when his father died.他在他父亲死的那一年离开了他的家乡.此时when作连词修饰that year,引导定语从句.

  3.状语从句:例如 He will go to the doctor`s when it is sunny.当天晴时,他就会去看医生.此时when引导状语,意思是“当...时候”.

  4.主语从句:例如When he left here is a question.他上面时候离开这儿的还没有人知道.此时when引导主语从句,意思是“什么时候”

  附:由“介词+关系代词”引导的定语从句

  1. 由“介词+关系代词”引导的定语从句主要用于正式文体,在非正式文体中通常将介词放至句末。如:this is the man to whom i referred. 我指的就是这个人。this is the man (whom) i referred to. 我指的就是这个人。

  2. 直接用于介词后作宾语的关系代词which不能换成that,直接用于介词后作宾语的关系代词whom不能换成who。但若介词用于句末,则用作宾语的which, whom也可换成that, who,或者省略不同。如:这是一个我们讨论了许多的问题。this is a subject about which we have talked a lot.(which不能换成that,也不能省略)this is a subject which we have talked about a lot. 这是一个我们讨论了许多的问题。(which可以换成that,也可以省略)

  3. 关系副词when, where, why根据情况有时可换成“介词+关系代词which”。如: that is the day when [=on which] he was born. 那就是他出生的日子。that is the house where [=in which] he lived. 那就是他住过的房子。that is the reason why [=for which] he must apologize. 那就是他必须道歉的原因。

  4. 在很正式的文体中,“介词+关系代词”引导的定语从句可紧缩成“介词+关系代词+不定式”结构。如:在那儿孩子们有个玩耍的花园。正:there the children had a garden in which to play. (很正式)正:there the children had a garden in which they could play. (较正式)正:there the children had a garden to play in. (较口语化)注:这类“介词+关系代词++不定式”结构中的介词不能没有,也不能放在句末。如不能说there the children had a garden which to play in.

  定语从句that

  that常用作关系代词,可指代某人,也可指代某物,指物时有的时候可用which替换that,指人时可用who替换。但在下列情况下,一般用that。

  一、that指代某物事时

  (3) Is there anything that I can do for you?

  有什么我可以帮你的吗?

  2. 先行词被all, every, no, some, any, (a)few, (a)little, much等限定词修饰时。如:

  (4) You can borrow any book that you want to read in our school library.

  3. 先行词被序数词或形容词最高级修饰时。如:

  5. 先行词是并列结构,既有人又有物时。如:

  6. 先行词前有the same 修饰,表示和先行词是同一物时。如:

  (12)They built a factory which produced things that had never been seen.

  他们建了一工厂,生产以前从未见过的东西。

  9. 以which作主语开头的特殊问句,为了避免重复,定语从句用that。如。

  10. 关系代词在定语从句中作表语时,而且通常省略。如:

  二、that 指代某人时。

  1. 泛指某人时。如:

  另外,that也可用作关系副词,表示时间、地点、原因和方式,在口语中可以用来代替when, where, why 引导的定语从句。在以下名词day, year, time, moment, reason, place等作先行词时,可用that作关系副词引导定语从句。如:
