　　介詞出現(xiàn)，一定要有賓語，所以　v.+prep.+賓語(n.)

　　at,after prep; off adv.

　　vt.+賓語

　　vi.+prep.+賓語

　?。?）過去進(jìn)行時態(tài)的概念和用法

　　過去進(jìn)行時態(tài)表示過去某時正在進(jìn)行的狀態(tài)或動作。過去進(jìn)行時的常用的時間狀語有阿at that moment, this morning, all

day yesterday, from nine to ten last evening等?？凑n文中的句子，標(biāo)志過去進(jìn)行時的時間狀語有： all morning， while，

when。

　　(2) 過去進(jìn)行時可以表示在過去某個時間點(diǎn)發(fā)生的事情。

　　When the plane arrived, some of the detectives were waiting inside the main building while others were waiting

on the airfield.

　　當(dāng)飛機(jī)到達(dá)時，一些偵探等候在主樓內(nèi)，另一些偵探則守候在停機(jī)坪上。

　?。?） 不是所有的動詞都能夠用過去進(jìn)行時態(tài)的。如 agree, be, believe, belong, forget, hate, hear, know等。

　　例如：

　　誤：I was knowing the answer.

　　正：I knew the answer. 我知道答案。

　　下面歸納一下通常不能用于過去進(jìn)行時的動詞：agree, be, believe, belong, care, forget, hate, have(擁有), hear,

know, like, love, mean, mind, notice, own, remember, seem, suppose, understand, want, wish等。

　　例如：

　?。?）、典型例題

　　1) Mary ___ a dress when she cut her finger.

　　A. made　 B. is making　 C. was making　 D. makes

　　答案C. 割傷手指是已發(fā)生的事情，應(yīng)用過去時。同　時，when表時間的同時性，"瑪麗在做衣服時"提供事情發(fā)生的背景，因

此用過去進(jìn)行時。

　　2) As she ___ the newspaper, Granny ___ asleep.

　　read； was falling　B. was reading； fell　C. was reading； was falling　D. read；fell

　　答案B.句中的as = when, while，意為"當(dāng)……之時"。描述一件事發(fā)生的背景時，用過去進(jìn)行；一個長動作發(fā)生的時候，另一

個短動作發(fā)生。句意為 "在她看報紙時，奶奶睡著了。"句中的 fell (fall的過去時)，是系動詞，后跟形容詞，如：fall sick。
