Look! The blackboard is so clean now. (他已经擦过黑板了。)这句话所表示的结果是黑板现在是干净的。现在完成时态，动作发生在过去，与现在的联系有两种（过去 现在），故其用法有两种。（涉及两个时间）1.表示过去发生的动作，没延续到现在，但对现在仍有影响。强调现在的状态。谓语动词是非延续性的。I closed the door just now.The door is closed now.I have closed the door.(关门的动作发生在过去，未延续到现在，只是对现在造成了影响，即强调门现在关上了。)影响 past now futureSomeone has broken the window. 有人把窗户打破了。（窗户现在仍然还是破的）Hes been ill. 他刚生过病。（指现在他的脸色还不好。）I have posted the photos.（强调照片不在我这了。）I have had my lunch. (强调我现在不饿了。)标志词：现在完成时态第一种用法常用already, yet, just, never, ever, before等adv.作状语。1）already，用于肯定句句中或句尾。变否、问句时，already变成yet.I have already posted the photos.I have posted the photos already.2) yet, 用于否定句和疑问句，位于句尾或助V.后。yet在否定句中意为“还，仍然”；在疑问句中意为“已经”。I havent yet posted the photos.Have you posted the photos yet? No, not yet.*I have already finished my work.(改为否定句和一般疑问句)I havent finished my work _.Have you finished you work _?3) before, 用于句尾，单独使用。（ago不独用，用于一般过去时）Have you read the book before?Ive never seen such a person before.4) just, ever, never用于助V.后，行为V.前。ever意为“曾经”,常用句型Have you ever.? 其否定回答常用never。例：Have you ever been to Beijing? (否定回答) Never.I have just / ever / never seen the film. 2. 表示过去发生的动作或状态持续到现在，还可能继续下去。谓语动词为延续性动词，句中常带有表示一段时间的时间状语，如：since结构，for+一段时间，recently, lately, these days; in the last / past three years by the end of ,（到为止）so far (到目前为止)， by now=up to now, today等。Shes been there for over two years 她在那两年多了。Theyve lived here since 1989/ since they came to this city.I have learned about 2000 English words so far. 注意：常用How long .? 提问现在完成时的时间。持续 past now future(二)谓语结构： have/has+过去分词1)have/has是助. has是三单形式2) 过去分词构成 A）规则构成 + ed (构成方法同过去式构成) a)直加ed workworked playplayed staystayed passpassed b)去加ed或直加d, likeliked livelived c)双写加ed, stopstopped dropdropped shopshopped triptripped shipshipped planplanned d) 辅y变i加ed, studystudied crycried worryworried B) 不规则构成 课本最后一页不规则动词表。C) +ed读音 _(三) 句型www.*肯定句：1）We have finished our homework. 2）She has seen the film.变否定句：_ _变一般疑问句并回答：_ _否定回答有时也可用“No，not yet.”或“No，never.”划线提问（特殊疑问句）：_ _3) He has done his homework for three hours.(划线提问) _(四)延续性动词和非延续性动词1）延续性动词：动作可持续一段时间，可和for, since等表示一段时间的时间状语连用。2）非延续性动词：动作不能持久，一瞬间就结束，不能延续，或表示一次性动作，也叫短暂性动词、瞬间动词、终止性动词。不能和表示一段时间的时间状语连用。常见这类动词有 come, go, leave, begin, start, arrive, reach, see, die, join, get up, borrow, lend, buy, finish, end, become, hear from等。*判断正误如有错误并改正:He has come back. ( )_He has come back for 3 days. ( )_I have borrowed the book. ( )_I have borrowed the book since last week. ( )_I have got up for an hour. ( )_He has died for 10 years. ( )_3)非延续性动词的否定式已成为一种可延续性状态，可以和for, since等表示一段时间的时间状语连用。I havent seen him for a long time. / since he left.I havent heard from him for half a year.I havent borrowed books for two months.4) 非延续性V. 可以转换为延续性V.，有以下几种情况：a)用相应的延续性动词buyhave; borrowkeep/have; put onwear; catch(get) a coldhave a cold; come/go/becomebe b)转换成“be + n.”形式join the Partybe a Party member join the armybe a soldiergo to schoolbe a studentc)转换成“be + adj./adv.”形式diebe dead; finishbe over; beginbe on; leavebe away; fall asleepbe asleep; wake upbe awake; get upbe up; closebe closed; openbe opend) 转换成“be + 介词短”语形式go to schoolbe
