(過(guò)去某時(shí)刻正在發(fā)生)I was typing a letter last night. 昨晚我在打一封信(可能沒(méi)打完) I typed some letters last night. 我昨晚打了一些信(已經(jīng)打完) I was reading the book at that time. (未讀完，“讀”的片段)I read the book yesterday. (已讀完，表整個(gè)“讀”)五、when 和while的用法區(qū)別 1. when是at or during the time that, 既指時(shí)間點(diǎn)，也可指一段時(shí)間； while是during the time that，只指一段時(shí)間，因此when引導(dǎo)的時(shí)間狀語(yǔ)從句中的動(dòng)詞可以是終止性動(dòng)詞，也可以是延續(xù)性動(dòng)詞，而while從句中的動(dòng)詞必須是延續(xù)性動(dòng)詞。 2. when 說(shuō)明從句的動(dòng)作和主句的動(dòng)作可以是同時(shí)，也可以是先后發(fā)生；while 則強(qiáng)調(diào)主句的動(dòng)作在從句動(dòng)作的發(fā)生的過(guò)程中或主從句兩個(gè)動(dòng)作同時(shí)發(fā)生。 3. 由when引導(dǎo)的時(shí)間狀語(yǔ)從句，主句用過(guò)去進(jìn)行時(shí)，從句應(yīng)用一般過(guò)去時(shí)；如果從句和主句的動(dòng)作同時(shí)發(fā)生，兩句都用過(guò)去進(jìn)行時(shí)的時(shí)候，多用while引導(dǎo)，如： （1）When the teacher came in, we were talking. 當(dāng)此句改變主從句的位置時(shí)，則為： （2）While we were talking, the teacher came in. （3）They were singing while we were dancing.過(guò)去進(jìn)行時(shí)練習(xí)題一、 選擇題。1.
