16、cooking?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。Just as I was leaving the house,you ca

17、me in.John was watching TV while his wife was talking with a neighbour over the phone.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，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?

18、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,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.W

19、hen 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The present perfect tense:Have/has+the past participleI have received a letter from L

20、ily recently.Has he handed in her homework yet?He has just gone to Beijing.They have never been to the USA.We have lived here for ten years.past perfect tense过去完成时由had+过去分词构成 表示过去的过去生的动作构成方式:肯定句:had+动词的过去分词否定句:had not+过去分词一般疑问句:had+主语+过去分词肯定回答:Yes,主语+had.否定回答:No,主语+hadnt.基本用法:1.过去完成时表示在过去某时或某个动作之前发生

26、在过去,更强调”过去的过去”,只有和过去的某时或某动作相比较时,才用到它.到目前为止我已经学会了3000个单词.到那时我已经学会了3000个英语单词.I have learned 3000 English words so far.I had learned 3000 English words till then.过去完成时与一般过去时的区别1.时间状语不同过去完成时在时间上强调“过去的过去”，而一般过去时只强调过去某一特定的时间 They had arrived at the station by ten yesterday.(说明不到点就在车站了）They arrived at the

27、station at ten yesterday.(说明点到车站的）2)在没有明确的时间状语做标志时，谓语动词动作发生的时间先后须依据上下文来判断，先发生的用过去完成时，后发生的用一般过去时I had finished my homework before my mother came back.在妈妈回来前，我已经把作业写完了。)当两个或两个以上的动作用and或but连接时，按时间顺序只需用一般过去时代替过去完成时；另外在引导的从句中由于这些连词本身已经表示时间的先后，因此也可以用过去时来代替过去完成时 He entered the room,turned onthe light and r
