They are working on the farm these days. 过 程 2. 基本结构： be(is/am/are)+ v-ing ⑴ be 的变化由主语决定。be 的口诀：I用_______, you用_______,is跟着_____, _______, _______.名词单数用______, 名词复数用________. ⑵ 动词ing现在分词的变化规则： ①一般在动词原型末尾+ing： do---doing teach---teaching read---reading； ②以一个元音字母+一个辅音字母结尾的单音节词，双写辅音字母再+ing： put---putting sit---sitting get---getting； ③ 以不发音字母e 结尾的，去掉e再+ing： make-making take-taking ； ④单词以辅音字母加－ie结尾，去-ie变y,再加-ing. die(死亡)----dying; tie（系）—tying lie(躺)--- lying 1

No, 主语+am/is/are not. 特殊疑问句：疑问词+ be + 主语+v-ing+其他？ Eg: 肯定句：I am watching TV now.我现在正在看电视。 否定句：__________________________________________________ 一般疑问句：______________________________________________ 肯定回答：__________________ 否定回答：__________________ 特殊疑问句：______________________________________________ 例题：1. I ____(write, am writing, is writing, are writing) a letter now. 2. Look, it _____(begin, is beginning, am beginning, are beginning) to rain. 3. They ____(study, is studying, am studying, are studying) medicine at the Medical Institute of Chengde these days. 4. He _____(teach, am teaching, is teaching, are teaching) an English lesson at this time. 【注意】1：一些表示位移的动词如go, come, leave, start, arrive等，用现在进行时可表示将来，表示计划，安排要做某事或表示马上将要发生的动作。 Eg： I’m coming. 我这就来。 I’m going/leaving. 我这就走。 When are you starting?你什么时候动身？ 【注意】2：表状态、感觉、情绪、精神活动的动词不可用于进行时，如： believe（相信），doubt（怀疑），hear，know，understand，belong（属于），think（认为），look（看起来），sound（听起来），taste（尝起来），show（展示），mind（介意）），have（有…）， care（在乎），like（喜欢），hate（讨厌），love（爱）等。 Eg：Danny: The doorbell is ringing. May: I know. I hear it. 3.【一般现在时与现在进行时的区别】 区别：现在进行时表示现阶段正在进行的动作，动作具有暂时性； 而一般现在时中的动作则具有长久性。 Eg: She is teaching at a night school now.目前她在一所夜校教书。(暂时在做) She teaches at a night school. 她在一所夜校教书。（长久做） 2

I was doing my homework from 7 to 9 yesterday evening. ⑵. 表示过去某时间点或时间段发生的事情。when从句表示时间点。 Eg: I was reading a book when he came in. He was cleaning the room when I saw him. ⑶ 两个动作（延续性）同时发生，主从句的动词都可用过去进行时。从句用when 或while引导。 Eg: Lily was learning music while Lucy was sleeping in her room. He was practising the piano when I was cooking. 4.when 与while区别： when＋从句，可以延续性动词(过去进行时)，也可以短暂性动词（一般过去时）； while＋从句,一定是延续性动词(过去进行时)。 Eg: 当我看到他的时候，他正在吃早饭。 He was having breakfast when I saw him.(时间点) ※ 总结：____while_____ 只能表示时间段，其后只能用过去进行时。 ※ __when_______ 既可表示某一个时间点，也可以表示某一个时间段，所以其后的动词可以时延续性动词，也可以是短暂性动词。 when一般接一般过去时 I was doing my homework when my father came home. while一般接进行时 While my mother was cleaning, I went out. ※ 5.【过去进行时与一般过去时的区别】： A.一般过去时往往表示某一动作已经完成，而过去进行时表示动作在持续或未完成。 Eg. She did her homework last night. ( 作业做完了) She was doing her homework last night.(作业不一定写完) B .一般过去时表示动作只做一次，而过去进行时表示动作反复进行。 Eg. He waved to me.(挥了挥手) He was waving to me.(不断地挥手) 例题：1. I _____(cook, cooked, was cooking, were cooking) breakfast when you arrived. 2.What ____you_____( do, did, was...doing, were…doing) at this time yesterday evening? 3

While/ When/ As we____( have, had, are having, were having) dinner, the doorbell rang. 三、现在完成时 .概念：表示发生在过去，持续到现在，可能刚刚结束也有可能继续进行下去的动作或状态，甚至延续到将来，并对现在造成一定的影响或结果。常与since+过去时（间）, for+一段时间连用。表示与现在有联系的过去的动作。 1、already / yet 已经 already一般用于肯定，与完成时态和进行时连用，也可以用于疑问句，表惊讶。 I have already finished my work. yet一般用于否定或疑问句。 Has she gone to school yet ? His parents haven’t been to Paris yet. 2、现在完成时表示从过去开始延续到现在的动作，常与for, since连用. 现在完成时表示动作才刚结束，但影响还在。 I have lost my pen .(结果是我的笔丢失了，我现在没有钢笔了) --have you found your watch yet ? --No , I haven’t found it yet. I have lived here for 10 years . 我已经在这里住了10年（可能还会继续住下去） 3、结构： 肯定句：主语+ have / has +V过分 疑问句：Have /Has + 主语+ V过分 否定句：主语+ haven’t / hasn’t + V过分 4、时间状语 yet, already, recently , just, once, never, ever, so far, these days. since +过去的时间点/过去时态 for + 一段时间 in the last(past) + 一段时间 grown into sth. （长大成为） feed dogs 喂养狗 5、延续和非延续动词。 在现在完成时中，有些动词不能与一段时间搭配，所以在与for , since 引导的肯定句搭配时，要用其他动词替代： 将非延续性动词转化为相应的状态动词。所谓状态动词就是指这一动作发生后接下来所呈现的状态。如： He has been asleep for an hour. （fall asleep,“入睡”为短暂动作，但be asleep“睡着”则为状态动词，可延续。） His father has been dead for three years.（die为短暂动词，“死”后的状态可用“be dead”这种系表结构来描述，可延续。） buy---have borrow---keep die---be dead go/leave/move---be away (from) begin/start---be on fall asleep---be asleep finish/end---be over join---be in/ be a +名词 come---be here open---be open close---be closed I’ve left the school for 3 years. ( ) I’ve been away from the school for 3 years. ( ) 4
