12、up 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

13、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.过去进行时往往与表示一段时间的状语连用，如all morning，all night，all day，all evening，the whole week等，表示这段时间一直

14、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 housework, my father was watching TV. 两个动作在同时段进行,

15、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 arriving 进行时态表示将要Exercises D1 As my father

16、 _ (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。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

17、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Exercise11 They have pulled down the old buildi
