It is time for sb. to do sth 到时间了 该了。It is time for you to go to bed. 你该睡觉了。 2It is time that sb. did sth. 时间已迟了早该了 ，It is time you went to bed.你早该睡觉了。 3. would rather sb. did sth.表示宁愿某人做某事。Id rather you came tomorrow.还是明天来吧。4） wish, wonder, think, hope 等用过去时，作试探性的询问、请求、建议等，而一般过去时表示的动作或状态都已成为过去，现已不复存在。I thought you might have some. 我以为你想要一些。注意： 用过去时表示现在，表示委婉语气。1） 动词want, hope, wonder, think, intend 等。Did you want anything else? 您还要些什么吗？ I wondered if you could help me. 能不能帮我一下。2）情态动词 could, would。Could you lend me your bike? 你的自行车，能借用一些吗？Used to / be used toused to + do：过去常常表示过去习惯性的动作或状态，但如今已不存在。Mother used not to be so forgetful.老妈过去没那么健忘。 Scarf used to take a walk. 斯卡夫过去常常散步。be used to + doing： 对已感到习惯，或习惯于，to是介词，后需加名词或动名词。He is used to a vegetarian diet. Scarf is used to taking a walk. 斯卡夫现在已习惯于散步了。2.一般过去时态的构成1）肯定句：主语+动词的过去式+其他 如：We enjoyed ourselves in the zoo yesterday. 我们昨天在动物园里玩得很高兴。2）否定句：主语+didnt +动词原形+其他如：We didnt enjoy ourselves in the zoo yesterday. 我们昨天在动物园里玩得不高兴。3）一般疑问句：Did +主语+动词原形+其他如：Did you enjoy yourselves in the zoo yesterday? 你们昨天在动物园里玩得高兴吗？【相关链接】在一般过去时态中会涉及到动词的过去式，大家要掌握规则动词的过去式的变化规则。变化规则如下：1）一般情况下，在动词原形后直接ed 。如：play played , look looked 。2）以e结尾的动词在其后加d。如：like liked, use used。3）与辅音字母加y结尾的动词，把y变成i 再加ed。 如：carry carried, marry - married。4）以重读闭音节（或r音节）结尾，末尾只有一个辅音字母时，双写这个辅音字母，再加ed。如： stop stopped, prefer preferred。当然，刚才提到的都是规则动词的构成，我们还学过许多不规则动词的过去式形式。如：put put, see saw, eat ate等，这些可需要我们在课下牢牢记住哟！【牵手中考】1.What _ to her yesterday evening?A. was happened B. happened C. happening D. happen2.

They were playing football at ten oclock yesterday morning. My mother was cooking when I got home. I was washing my clothes at this time yesterday. 2) 过去某阶段持续进行的动作 What were you doing during the holiday? 另外，在复合句中，若主要动作和背景动作是同时发生的，那么主从句都可用过去进行时e.g. Jenny was reading while Danny was writing.3）其结构是助动词be的过去形式was/were +v-ing. 其句式变化仍然要在be上做文章。E.g. We were working in class. We werent working in class. Were you working in class? 过去进行时常与过去某一特定时间的状语连用，如 last night, at that time, at noon yesterday, last Sunday 等。 也有时没有时间状语，要通过上下文的暗示来确定用过去进行时。E.g. The students all worked hard. Everyone knew what he was working for.做题时常见错误如下： 一、易把be+现在分词记成be+过去分词 例：He was talked (talk) to his mum at that time. 答案：was talking 解析：过去进行时与现在进行时结构上的区别体现在be动词上。 二、丢掉be动词或忘记把动词变成现在分词 例：1 I watching (watch) TV when he came in. 2 They were play (play) games at 5:00 p.m. yesterday. 答案：1 was watching 2 were playing 解析：现在进行时中“be+现在分词,缺一不可”的规律也可应用于过去进行时。三、对动词或动词词组提问时丢掉doing例：We were flying kites at 5:00 p.m. yesterday. (对划线部分提问) What were you at 5:00 p.m. yesterday?答案：What were you doing at 5:00 p.m. yesterday?解析：现在进行时中“Whatdoing”?句式同样适用于过去进行时。四、易与现在进行时弄混例：My mother is cooking (cook)when I got home.答案：was cooking 解析：这两种时态的共同点是都表示动作正在进行，但现在进行时前提是现在，而过去进行时前提是过去，由when I got home可看出前提是过去。五、易与一般过去时弄混例：昨晚我在读一本故事书。 I read (read) a story book yesterday evening.答案：was reading 解析：这两种时态的共同点是都用于表示过去发生的动作。但过去进行时强调动作正在进行，而一般过去时则表示过去某一时间所发生的动作或存在的状态，它表示的动作往往已经完成。“在”说明正在进行，而“I read a story book yesterday evening.”的意思是昨晚我读了一本故事书，言下之意已经读完了。故用过去进行时。 另外，在宾语从句中当主句为过去时，从句若是现在进行时，需变成过去进行时。 e.g. He said that he was drawing a cat at noon yesterday.典型例题(1) Mary _C_ a dress when she cut her finger. A. made B. is making C. was making D. makes (2) As she _ the newspaper, Granny _ asleep. A. read； was falling B. was reading； fell C. was reading； was falling D. read；fell 专项训练：一 、单选1 What _ from three to four yesterday afternoon?A have you done B had you done C did you do D were you doing2 I call you yesterday evening, but there was no answer. - Oh., Im sorry I _ dinner at my friends home.A home B had C was having D have had3 My mother _ while my father _TV.A cooked; was watching B was cooking; was watching C was cooked; watched D cooked; watched4 When I got home, my son _ the music.A am listening to B listened to C was listening to D was listening5 We heard a cry when we _ TV last night.A were watching B would watch C watch D watched6 She asked him whether he _ back for lunch.A come B was coming C came D had come7 Could you tell me when _?A she is coming B she was coming C will be come D is he coming8 The teacher _ when I came into the classroom.A is drawing B draws C has drawn D was drawing 二 、填空1 _ they_ (feed) the animals at 5:00 yesterday afternoon?2 Mrs. Green _ _ (not wash) clothes at this time yesterday.3 Grandpa _ _ (mend) his clock when I reached home. 4 As I _ (walk) in the park, I saw some children playing games.五、一般将来时1.一般将来时的用法1） shall用于第一人称，常被will 所代替。will 在陈述句中用于各人称，在征求意见时常用于第二人称。Which paragraph shall I read first？ 我先读哪一段呢？ Will you be at home at seven this evening? 今晚七点回家好吗？2）be going to +不定式，表示将来。a. 主语的意图，即将做某事。What are you going to do tomorrow? 明天打算作什么呢？b. 计划，安排要发生的事。The play is going to be produced next month。这出戏下月开播。c. 有迹象要发生的事。Look at the dark clouds, there is going to be a storm. 看那乌云，快要下雨了。3) be +不定式表将来，按计划或正式安排将发生的事。We are to discuss the report next Saturday.我们下星期六讨论这份报告。4）be about to +不定式，意为马上做某事。 He is about to leave for Beijing. 他马上要去北京。注意：be about to do 不能与tomorrow, next week 等表示明确将来时的时间状语连用。be going to / will 用于条件句时，be going to表将来,will表意愿。例如：If you are going to make a journey, youd better get ready for it as soon as possible.Now if you will take off your clothes, we will fit the new clothes on you in front of the mirror.be to和be going tobe to 表示客观安排或受人指示而做某事，be going to 表示主观的打算或计划。I am to play football tomorrow afternoon.明天下午我去踢球。（客观安排）Im going to play football tomorrow afternoon. 明天下午我想去踢球。（主观安排）2.一般现在时表将来1）下列动词come, go, arrive, leave, start, begin, return的一般现在时可以表示将来，主要用来表示在时间上已确定或安排好的事情。 The train leaves at six tomorrow morning. 火车明天上午六点开。 When does the bus star? It stars in ten minutes. 汽车什么时候开？十分钟后。2）以here, there等开始的倒装句，表示动作正在进行。 Her
