14、ater.,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和as一般不这么用。,John was watching

17、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 D,1 As my father _(leave)the house,the postman _(arrive).was lea

18、ving;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,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 wal
