Did you have a party the other day?Lei Feng was a good soldier in the old days. 2. 表示过去连续发生的动作时,要用过去时,这种情况下,往往没有表示过去的时间状语,而通过上下文来表示。Eg.The boy opened his eyes for a moment,looked at the captain,and then died. 3. 表示过去一段时间内经常或反复的动作,常与always,never等连用。Eg.Mrs. Peter always carried an umbrella.(只是说明她过去的动作,不表明她现在是否常带着伞。)比较: Mrs. Peter always carries an umbrella.(说明这是她的习惯,表明她现在仍然还习惯总带着一把伞)Mrs. Peter is always carrying an umbrella.彼得太太 总是带着一把伞。(表示说话者对这一动作或行为厌烦)4. 如果强调已经终止的习惯时要用 used to do(过去常常做,而现在不那样做了)He used to drink.(意味着他现在不喝酒了。喝酒这个动作终止了)I used to take a walk in the morning.(意味着现在不在早晨散步了)比较:I took a walk in the morning.(只是说明过去这一动作)5 有些句子,虽然没有表示过去确定时间的状语,但实际上是指过去发生的动作或存在的状态的话,也要用过去时,这一点,我们中国学生往往出错,要特别注意!I didnt know you were in Paris.我不知道你在巴黎。(因为在说话时,我已经知道你在巴黎了。这句话指的是说话之前,所以只能用过去时表示。实际上,这句话暗指:But now I know you are here.)I thought you were ill. (这句话应是在说话之前,我以为你病了。但是现在我知道你没病)辨别正误 Li Ming studied English this morning.把此句变为一般疑问句1.Did Li Ming studied English this morning?动词应该用_2. Does Li Ming Study English this morning?时态应该用_3.Was Li Ming studied English this morning应该用_而不是be动词三、一般过去时的基本结构一般过去式的构成形式: 肯定式疑问式否定式I workedDid I work?I did not workHe(she,it) workedDid he(she,it) work?He (she,it)did not workWe workedDid we work?We did not workYou workedDid you work?You did not workThey workedDid they work?They did not work否定形式:be动词前:were not行为动词前: did not+实义动词原形一般疑问句:be动词前:was或were放于句首;行为动词前:用助动词do的过去式did 提问,同时还原行为动词。一般过去时专项练习一 选择( )1.

There are some apples on the table. 2. 若句子中有几个并列的主语时,be的形式要与离其最近的一个主语在人称和数上保持一致。如:There is a boy, a girl and two women in the house. There are ten students and a teacher in the office. 第三关::There be 结构的句型转换1. 否定句: there be的否定式通常在be后加not构成(在口语中be时常与not缩写在一起)。如果句中有some,一般要变成any。如:There are some children in the picture. There arent any children in the picture.2. 一般疑问句及其答语:把be提到there前,首字母大写,句末用问号即可。其肯定答语是Yes, there is / are;否定答语为No, there isnt / arent。如:-Are there two cats in the tree?-Yes, there are. (No, there arent.)第四关:There be 与 haveThere be与 have都可表示“有”的含义。但have表所有关系,there be表“存在”,侧重的重点不同;并且have前必须有人作主语。例如:There are some children in the garden.She has three daughters and two sons.百看不如一练用刚刚学到的句型翻译下列句子。例如:有桌子上有一条鱼。答:There is a fish on the table.1在桌子上有一个苹果._2) 在篮子里有八个西红柿._3) 在教室里有一个老师和八个学生._4) 在教室里有八个学生和一个老师._变下列句子为否定句.1) There is a big watermelon on the table._2) There are eight children in the classroom._3) There are many books in the bag._变下列句子为一般疑问句.1) There is a dog on the chair._2) There is some fruit on the table._3) There are many pencils in the pencil case._中考原题1There are _ days in a week Athe seven Bseventh Cthe seventh Dseven 2There are few _ in the fridgeLets go and buy som e peas,carrots and cabbages Avegetables Bfruit Cmeat Deggs 3Look!There are some _ on the floor Achild Bwater Cboxes Dgirl 4There were two _ people at yesterdays meeting Ahundreds Bhundreds of Chundred 5The letter from my uncle was shortThere wasnt _ news Amany Ba few Cmuch Dfew 6Oh,there isnt enough _ for us in the lift It doesnt matter,lets wait for the next Aground Bfloor Cplace Droom 7There _ an English Evening next Tuesday Awas Bwill be Cwill have Dare going to be 8There _ a football gam e in our school Ahas Bwill have Cwill be 9There is going to _ a report _ Chinese history in our school this evening Ahave;on Bbe;on Chave;for Dbe;of 10There is _ food hereWell have to buy some Aany Bsome Cno 11There is _ in the bagIts em pty Anothing Bsomething Canything Dsomebody 12There is _ knocking at the doorGo and see who it is Anobody Bsomebody Canybody Deverybody 13Is there _ wrong with me, doctor?
