语法 Grammar in use

一般过去时

在第3课及第27课的语法中我们都学习了一般过去时。在一段文字中,初次使用一般过去时的时候通常要有明确的时间状语,随后的叙述则可以不一定使用时间状语;如果不加before, after等词语,过去的动作就被认为是按所描述的顺序发生的:

One afternoon she set out from the coast in a small boat and was caught in a storm. Towards evening, the boat struck a rock and the girl jumped into the sea.

一天下午,她乘小船从海岸出发,遇上了风暴。天将黑时,小船撞在了一块礁石上,姑娘跳进了海里。

与一般过去时常用的两个词是once和recently:

I went on an excursion recently.

最近我作了一次短途旅行。

recently在表示“最近一段时期”时也可以与现在完成时连用:I haven't heard from him recently.

我最近没有收到他的信。

一般过去时也可以用于时间状语从句中:
