定語從句的when

=when作爲定語從句的引導詞時,表示時間,在從句中充當時間狀語,後面需要加上完整的陳述語序。

定語從句的when

  句式如下:

表示時間的名詞+when+完整陳述句+句子其它成分。

when引導的定語從句可以放在主語,賓語或者表語,甚至爲名詞的.賓補之後。

例:

The night when we took a stroll in the park was so cold.

咱們在公園散步的那個晚上好冷。

night 做主語,被定語從句when we took a stroll in the park 修飾。

I remember the night when we took a stroll in the park.

我記得那個咱們一起在公園散步的夜晚。

night變成了賓語,被定語從句when we took a stroll in the park修飾。

What I can never forget is the night when we took a stroll in the park.

我永不能忘記的是咱們一起在公園散步的那個夜晚。

night變成了表語,被定語從句when we took a stroll in the park修飾。

以上三組例句中,when後面所接的都是完整句,並且when 後的從句時態和主句一致。前提是when充當的從句的時間狀語,相當於是at the night.

所以,以上三句,可以把when都改成at which。

  寫作必備when引導定語從句句式:

There was a time when...... 曾經。。。

There was a time when people were never bothered by pollution.

曾經人們不用爲污染煩憂。

We all experience a day when......我們都經歷過。。。

We all experience a day when everything goes wrong.

我們都經歷過事事不順心的一天。

we can never ignore the time when......我們絕不能忽視。。。

We can never ignore the time when computers penetrate our life and study.

我們不能忽視這個電腦滲透進我們的生活和學習的年代。

  關係副詞引導的定語從句

關係副詞可代替的先行詞是表示時間、地點或理由的名詞,在從句中作狀語。

1)關係副詞when, where, why的含義相當於"介詞+which"結構,因此常常和"介詞+ which"結構交替使用。

例如:

There are occasions when (on which) one must yield.

任何人都有不得不屈服的時候。

Beijing is the place where (in which) I was born.

北京是我的出生地。

Is this the reason why (for which) he refused our offer?

這就是他拒絕我們幫助他的理由嗎?

2)that代替關係副詞,可以用於表示時間、地點、方式、理由的名詞後代替when, where, why和“介+which”引導的定語從句,在口語中that常被省略。

例如:

His father died the year (that/when/in which) he was born.

他父親在他出生那年逝世了。

He is unlikely to find the place (that/where/in which) he lived forty years ago.他不大可能找到他四十年前居住過的地方。
