关系副词用法

1. where指地点，在定语从句中做地点状语用来表示地点的定语从句。

(1) Shanghai is the city where I was born.

(2) The house where I lived ten y ears ago has been pulled down.

2. when引导定语从句表示时间。在定语从句中做时间状语也可做连接词用

(1) I still remember the day when I first came to the school.

(2) The time when we got together finally came.

[注]表示时间"time"一词的定语从句只用when引导，有时不用任何关系代词，当然也不用that引导。

By the time you arrived in London, we had stayed there for two weeks.

到你到达伦敦的时候，我们在那里已经待了两个星期。

I still remember the first time I met her. 我仍然记得我第一次见到她。

Each time he goes to business trip, he brings a lot of living necessities, such as towels, soap, toothbrush etc。

每一次他去出差，他带来了生活必需品，如毛巾，肥皂，牙刷等，很多。

3. why指原因 在定语从句中做原因状语

(1) Please tell me the reason why you missed the plane.

(2) I don't know the reason why he looks unhappy today.

注意：关系副词引导的从句可以由"介词 关系代词"引导的从句替换

(1) The reason why/ for which he refused the invitation is not clear,

(2) From the year when/in which he was going to school he began to know what he wanted when he grew up.

注：1)介词后面的关系代词不能省略。

2)that前不能有介词。

3) 某些在从句中充当时间，地点或原因状语的"介词 关系词"结构可以同关系副词when ,where和why 互换。

This is the house in which I lived two years ago.

This is the house where I lived two years ago.
