    遵循:主過從過 主現從現 主將從現

    【1】在過去,when從句和主句的動作先後發生

    解釋:表示在過去,主句和從句包含的動作先後發生了,或者主句或從句的動作先發生。

    句子結構:when從句和主句都用過去式。

    例句:When I lived in the countryside, I usedto carry some water for him.

    當住在農村時,我常常為他擔水。

    When they began to talk about him hepricked his ears.

    當他們開始議論到他時,他豎起了耳朵。

    His friends fell off one by one when hewas in adversity.

    在他身處逆境時,他的朋友一個接一個離他而去。

    說明:主句過去式常用 was(were) about to, was(were) on the point 等片語。如:

    We were about to leave when he came in.

    我們就要離開,就在那時他進來了。

    We were about to start when it began torain.

    我們剛要出發就開始下雨了。

    【2】在過去,主句動作發生時,when從句動作正進行

    解釋:表示在過去,當主句的包含動作發生時,從句的動作在當時也正在進行。此類句子主句動詞為瞬間性,從句動詞為延續性。

    句子結構:when從句用過去進行時,主句用過去式。

    例句:When rolling down the hill, he snatchedat a rock.

    在向山下滾的過程中,他一把抓住了一塊岩石。

    When running, he stumbled me.

    跑動之中他把我絆倒了。

    當我吃早飯的時候,我爸爸就出門了。

    I was thinking of this when I heard myname called.

    當突然聽到有人叫我時,我正想著這件事時。
