三、過去進(jìn)行時(shí)的用法詳解

(1) 表示在過去某一時(shí)間正在進(jìn)行的動(dòng)作，此時(shí)句中往往有表示過去的時(shí)間狀語

then,atthat time,this time,yesterday等。

I was doing my homework when my mother came to home.

(2)敘述在過去的同一時(shí)間都在進(jìn)行的幾個(gè)動(dòng)作，通常用

While I was studying at college while my brother was teaching at university.

(3)表示在過去某一段時(shí)間內(nèi)一直持續(xù)進(jìn)行的動(dòng)作

They were expecting you yesterday, but you didn’t turn up.

四、 使用過去進(jìn)行時(shí)應(yīng)注意的幾點(diǎn)

(1)過去進(jìn)行時(shí)可表示按計(jì)劃、安排過去某時(shí)刻將要發(fā)生的動(dòng)作。如：

He said they were leaving for Beijing this afternoon.他說他今天下午要去北京。

(2) 動(dòng)詞hope, wonder等的過去進(jìn)行時(shí)常用來表示提出要求，雖然表示現(xiàn)在的內(nèi)容，但語氣比一般現(xiàn)在時(shí)或一般過去時(shí)要委婉。如：

I was wondering whether you could come to join us.我想你能否過來跟我們一起活動(dòng)?

(3)過去進(jìn)行時(shí)中有always, forever, continually, constantly修飾時(shí)，表示說話人的贊賞或厭煩的感情。如：【這點(diǎn)需要重點(diǎn)注意】

He was always thinking of others.他總是想到人家。

五、 過去進(jìn)行時(shí)與一般過去時(shí)的區(qū)別【友情提示：中考重點(diǎn)】

(1) 過去進(jìn)行時(shí)強(qiáng)調(diào)動(dòng)作在過去某時(shí)刻正在進(jìn)行或持續(xù)，而一般過去時(shí)表示動(dòng)作的完成。如： He was writing his composition last night.他昨晚在寫作文。

(不一定寫完) He wrote his composition last night.他昨晚寫了一篇作文。(已經(jīng)寫完)

(2) 表示過去的狀態(tài)、感覺及心理活動(dòng)的靜態(tài)動(dòng)詞(如n, hear, sbe, like, love, hate, fear,owee, know, want, notice)可用于一般過去時(shí)，但通常不用于進(jìn)行時(shí)。如：

I hated it when a man spoke with his mouth full of food. 我討厭人們說話時(shí)口里含著食物。

(3)一般過去時(shí)與always, constantly, forever, continually等連用，表示“過去經(jīng)常性、習(xí)慣性的動(dòng)作”;而過去進(jìn)行時(shí)與always, constantly, forever, continually等連用，表示動(dòng)作的重復(fù)，常帶有感****彩。如：

He always got up at six. 他過去總是六點(diǎn)起床。

He was always thinking of his work.他總是一心想到工作。

(4) 有時(shí)過去進(jìn)行時(shí)可以用來替換一般過去時(shí)，但一般過去時(shí)表示主語的行為是經(jīng)過認(rèn)真的，而過去進(jìn)行時(shí)表示比較隨意或者沒有進(jìn)行仔細(xì)思考的行為，如：

I thought that he would agree with us. 我原以為它會(huì)同意我們的。

I was thinking of persuading him to follow my advice. 我想到了要說服他接受我們的建議。
