13、eir surprise, the precious parcel was full of stones and sand!were keeping guard at the door, two others opened the parcel.表面上是分工, 两个动作同时发生, 不是同时开始同时结束, 延续时间不一致, 长一点时间的动作用进行时态, 短时间的动作用过去时.When someone knocked at the door, I was having dinner.keep guard 守卫 They kept a close guard over the thieves.at

15、as full of books. The cup is full of water.【Key structures】过去进行时: 过去进行时的构成：be的过去式+现在分词过去进行时和一般过去时经常同在一个句子里使用。过去进行时表示过去正在进行的动作或情况，一般过去时则表示比较短暂的动作或事件。正在进行中的动作或情况往往由连词when，while，as，just as等引导。when，while 当时候（强调动作同时发生）while+从句, 动词一定是延续性动词when+延续性动词/瞬间动词while 能用when 代替，但是when 却不一定能用while 代替。while 通常只引导持续时

16、间较长的动作，并且主句和从句可以同时用过去进行时，而when 和as一般不这么用。John was watching TV while his wife was talking with a neighbour over the phone.Just as I was leaving the house, you came in.when 也可以引导比较短暂的动作，while和as则一般不行。We were having supper when the lights went out. (go out 熄灭)过去进行时往往与表示一段时间的状语连用，如all morning，all night，

17、all day，all evening，the whole week等，表示这段时间一直在干什么。What were you doing all evening? I couldnt find you anywhere.过去动作同时发生的时态 过去两个动作同时发生, 习惯上一个用一般过去时, 另一个用过去进行时；动作长用过去进行时,动作短用一般过去时; 分工的情况, 动作的开始时间和结束时间几乎相同, 均用过去进行时;I was listening to the radio, my sister was dancing.When my mother was doing the housewor

18、k, my father was watching TV. 两个动作在同时段进行, 在不同时间结束, 先发生的动作未结束, 另一个动作发生, 先发生的动作用进行时态, 另一个动作用过去时.When I was opening the door, the telephone rang.先开门When the telephone was ringing, I opened the door. 电话先响 瞬间动词（如：arrive）没有进行时态, 所以两个动作同时发生, 延续性动词用进行时态, 瞬间动词使用过去时态.When he arrived, I was having dinner. I am

19、 arriving 进行时态表示将要ExercisesD1 As my father _ (leave) the house, the postman _ (arrive).was leaving；arrived(两个瞬间动词同时发生可能性很小, 应具体分析, 故用进行时态表将来)5 While mother _ (prepare) lunch, Janet _ (set) the table.set the table摆桌子 was preparing；set【Special Difficulties】短语动词中的小品词：许多动词加上介词或副词后就会改变词义，这些介词和副词通常被称为小品词。

20、它们没有词形的变化。有些小品词既可以作介词又可以作副词。判断一个小品词是副词还是介词要看小品词有没有带宾语。有宾语的是介词，没有宾语的是副词，介词的位置相对固定，不能变动。 vi.&vt.+ prep./adv.+宾语(n.) She is walking up the hill. vt.+宾语(n./pron.)+adv.take off the coat =take the coat off =take it offput on your shoes =put your shoes on =put them onI always take money with me.我身上总带些钱
