过去进行时的时间状语
1. when 和while引导的状语从句中,强调某个动作正在进行的过程中时要用进行时态,while表示一段时间,因此它所引导的状语从句中,谓语动词常用进行时态,如:
When/While we were having supper, the light went out. 我们正在吃饭时灯熄灭了。
2. when用作并列连词时,主句常用进行时态,从句则用一般过去时,表示主句动作发生的过程中,另一个意想不到的动作发生了。如:
I was walking in the street when someone called me. 我正在街上走时突然有人喊我。
下面几种情况不用一般过去时而要用过去进行时:
1. 表示过去某一阶段暂时性的习惯动作时。如:
Tom was getting up at six o‘clock every day that week. 汤姆那一周里每天都是六点钟起床。
2. 与always连用表示赞美,厌烦等感情色彩时。如:
John was always coming to school late. 约翰上学总是迟到。
Lei Feng was always doing good deeds for the people. 雷锋总是为人民做好事。
3. 用来描写故事发生的情景时。如:
It was a dark night. The wind was blowing hard and the rain was falling heavily. A PLA man suddenly appeared on the river bank. He wanted to cross the river.那是一个漆黑的夜晚,风刮得很厉害,雨下得很大,一个解放军战士突然出现在河岸上,他想过河去。
4. when作并列连词,表示“(这时)突然”之意时,第一个并列分句用过去进行时,when引导的并列分句用一般过去时。如:
I was taking a walk when I met him. 我正在散步,突然遇见了他。
We were playing outside when it began to rain. 我们正在外边玩,这时下起雨来了。
5. go, come, leave, start, arrive等动词可用过去进行时表示过去将来的含义。如:
I was leaving for Wuhan that day. 那天我正要去武汉。
She was coming later. 她随后就来。
过去进行时表示婉转语气(只限于want, hope, wonder 等动词),用以提出请求。如:
I was wondering if you could help me.
I was hoping you could send me home.
