英語動詞時態(tài)用法歸納：過去進行時

1. 構(gòu)成

was / were+動詞的現(xiàn)在分詞。

2. 基本用法

(1) 表示過去某一時間點或一段時間正在進行的動作。如：

What were you doing this time yesterday? 你昨天這個時候在干什么？

Granny fell asleep when she was reading. 奶奶看書時睡著了。

He was writing a book about grammar last year, but I don’t know whether he has finished it.他去年在寫一本語法方面的書，但我不知道他現(xiàn)在是否寫完了。

What were you talking about just now? 你們剛才在談什么？

He was working from 7 to 11 last night. 昨晚他從七點一直工作到十一點。

(2) 過去進行時與 always, forever, continually等副詞連用，表示滿意、稱贊、驚訝、厭惡等表示感情色彩。如：

My brother was always losing his keys. 我哥哥老是丟鑰匙。

The boy was continually asking the same question. 這個男孩子老是問同一個問題。

(3)動詞wonder, hope, think, want等的過去進行時表示語氣委婉、客氣。如：

I was hoping you give me a chance to try the job. 我很希望你給我一個機會來試一試這個工作。

(4)過去進行時表將來。如：

—What were you doing when he came to see you?

—I had just finished my homework and was leaving to 

He said his brother was leaving for Japan tomorrow. 他說他哥哥明天要去日本。 

3. 過去進行時和一般過去時的區(qū)別

(1) 過去進行時通常表示一個過去正在進行的動作；而一般過去時則通常表示一個過去已經(jīng)完成的動作。如：

I was reading the newspaper last night. 我昨晚在看書。(不一定看完)

I read the newspaper last night. 我昨晚看了報紙。(已經(jīng)看完)

He was building a model ship out of wood. 他在那里修一座橋。(不一定建成)

He built a model ship out of wood. 他用木頭造了個模型船。(已建成)

(2) 少數(shù)動詞如rain, snow, cough, wear, feel, work等的一般過去時并不表示動作完成，這時用兩種時態(tài)都可以，且含義區(qū)別不大。如：

It snowed / was snowing all day yesterday. 昨天下了一天的雪。

She didn’t feel / wasn’t feeling well that day. 那天她感到不太舒服。

The child coughed / was coughing all night. 這孩子咳嗽了一整夜。
