3.語法
1. 過去進行時
2. 情態動詞的用法Ⅱ
【重難點分析】
一. 過去進行時
過去進行時表示過去某一時刻或者某段時間正在進行或發生的動作,常和表過去的時間狀語連用,如:
I was doing my homework at this time yesterday.昨天的這個時候我正在做作業。
They were waiting for you yesterday.他們昨天一直在等你。
過去進行時的構成:
肯定形式:主語+was/were+V-ing
否定形式:主語+was not (wasn't)/were not (weren't)+V-ing
疑問形式:Was/Were+主語+V-ing。
基本用法:
1.過去進行時表示過去某一段時間或某一時刻正在進行的動作。常與之連用的時間狀語有,at that time/moment, (at) this time yesterday (last night/Sunday/week…), at+點鍾+yesterday (last night / Sunday…),when sb. did sth等時間狀語從句,如:
What were you doing at 7p.m. yesterday? 昨天晚上七點你在干什麼?
I first met Mary three years ago. She was working at a radio shop at the time. 我第一次遇到瑪麗是在三年前,當時她在一家無線電商店工作。
I was cooking when she knocked at the door. 她敲門時我正在做飯。
2. when後通常用表示暫短性動詞,while後通常用表示持續性動詞,因此它所引導的狀語從句中,謂語動詞常用進行時態,如:
When the car exploded I was walking past it.= While I was walking past the car it exploded.
3.when用作並列連詞時,主句常用進行時態,從句則用一般過去時,表示主句動作發生的過程中,另一個意想不到的動作發生了。如:
I was walking in the street when someone called me. 我正在街上走時突然有人喊我。
4. when作並列連詞,表示「(這時)突然」之意時,第一個並列分句用過去進行時,when引導的並列分句用一般過去時。如:
I was taking a walk when I met him. 我正在散步,突然遇見了他。
We were playing outside when it began to rain. 我們正在外邊玩,這時下起雨來了。
