　　vt.+宾语

　　vi.+prep.+宾语

　　Right: They always want a cup of tea after lunch.

　　{ False: He is sending now.

　　B 有些动词只是不及物动词；它们可以单独用，如果后面想接宾语，动词后面必须加上介词。

　　三、时态重点

　　过去进行时

　　They were expecting a valuable parcel of diamonds from South Africa.

　　The plane was late and detectives were waiting at the airport all morning.

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

on the airfield.

　　While two detectives were keeping guard at the door, two others opened the parcel.

　　（1）过去进行时态的概念和用法

　　过去进行时态表示过去某时正在进行的状态或动作。过去进行时的常用的时间状语有阿at that moment, this morning, all

day yesterday, from nine to ten last evening等。看课文中的句子，标志过去进行时的时间状语有： all morning， while，

when。

　　(2) 过去进行时可以表示在过去某个时间点发生的事情。

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

on the airfield.

　　当飞机到达时，一些侦探等候在主楼内，另一些侦探则守候在停机坪上。

　　（3） 不是所有的动词都能够用过去进行时态的。如 agree, be, believe, belong, forget, hate, hear, know等。

　　例如：

　　误：I was knowing the answer.

　　正：I knew the answer. 我知道答案。

　　下面归纳一下通常不能用于过去进行时的动词：agree, be, believe, belong, care, forget, hate, have(拥有), hear,

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

　　例如：

　　误：I was knowing the answer.

　　正：I knew the answer. 我知道答案。

　　误：I wasn't understanding him.

　　正：I didn't understand him. 我不明白他的意思。

　　（4）、典型例题

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

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

　　答案C. 割伤手指是已发生的事情，应用过去时。同　时，when表时间的同时性，"玛丽在做衣服时"提供事情发生的背景，因

此用过去进行时。

　　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，意为"当……之时"。描述一件事发生的背景时，用过去进行；一个长动作发生的时候，另一

个短动作发生。句意为 "在她看报纸时，奶奶睡着了。"句中的 fell (fall的过去时)，是系动词，后跟形容词，如：fall sick。

　　牛刀小试：

　　1 What ______ from three to four yesterday afternoon?

　　A have you done B had you done C did you do D were you doing

　　2 - I call you yesterday evening, but there was no answer.

　　- Oh., I'm sorry I _____ dinner at my friend's home.

　　A home B had C was having D have had

　　3 My mother _____ while my father _____TV.

　　A cooked; was watching B was cooking; was watching

　　C was cooked; watched D cooked; watched

　　4 When I got home, my son _____ the music.
