Lesson 89 语法讲解 现在完成时中for和since引导的时间状语: 【用法】1. 现在完成时还可以描述发生在过去且一直延续到现在的动作，这种动作甚至有可能延续下去。 for + 一段时间 — “有……时间” since + 时间点 或 since + 句子（一般过去时）— “自从……到现在” 用疑问词组how long对以上结构进行提问。 Lesson 89 语法讲解 e.g. How long has Ian lived in the house? 伊恩在这幢房子里住多久了。 He has lived here for twenty years. 他在这里住了20年了。 He has stayed here since 3 o’clock. 他自从3点就待在这里。 He has taught English since he came here. 自从他来这里就开始教英语。 注意：since后的句子用一般过去时。 Lesson 89 语法讲解 2. 除了for和since之外， 常和现在完成时连用的时间状语还有in the past few years（在过去的几年中），over the last thirty years（在过去的30年中），so far/up to now/till now（迄今为止），recently（近来），these days（这段日子）等。 e.g. Great changes have taken place in China in the past few years. 在过去的几年中，中国发生的巨大的变化。 I have never been abroad up to now. 到现在为止我还没有出过国。 Lesson 89 语法讲解 3. 在此种情况中，现在完成时的谓语动词必须是延续性动词，如果是非延续性性动词，要转换成延续性动词。 在英语中，动词按其动作发生的方式、动作发生过程的长短，可分为延续性动词和非延续性动词。      延续性动词表示能够延续的动作，这种动作可以延续下去或产生持久影响。此类动词常见的如：learn, work, stand, lie, know, walk, keep, have, wait, watch, sing, read, sleep, live, stay等。 Lesson 89 语法讲解 非延续性动词也称终止性动词、瞬间动词或短暂性动词，表示不能延续的动作，这种动作发生后立即结束。此类动词常见的如open, close, finish, begin, come, go, arrive, reach, get to, leave, move, borrow, buy等。 在现在完成时中，延续性动词可与表示“时间段”的状语连用。 He has lived here for 6 years.他在这儿已住了六年了。 I have learned English since I came here.自从我来到这儿就学英语了。 Lesson 89 语法讲解  非延续性动词表示的动作极其短暂，不能持续。因此，不可与表示一段时间的状语连用。试比较：  史密斯先生来这儿五天了。      误：Mr. Smith has come here for five days.     正：Mr. Smith has been here for five days.     正：Mr. Smith came here five days ago.     正：It is/has been five days since Mr. Smith came here.     正：Five days has passed since Mr. Smith came here. Lesson 89 语法讲解 非延续性动词，不能与表示“时间段”的状语连用。可采用以下方法，将句中非延续性动词转换为相应的延续性动词，常见转换类型： buy – have get up – be up borrow – keep begin/start – be on leave – be away move to – live in die – be dead catch a cold – have a cold open – be open join – be in/be a member of close – be closed go out – be out finish – be over put on – be on arrive – be here begin to work – work Lesson 90 Have you...yet? 版权声明 感谢您下载平台上提供的PPT作品，为了您和熊猫办公以及原创作者的利益，请勿复制、传播、销售，否则将承担法律责任！熊猫办公将对作品进行维权，按照传播下载次数进行十倍的索取赔偿！ 1.在熊猫办公出售的PPT模板是免版税类（RF：Royalty-Free）正版受《中国人民共和国著作法》和《世界版权公约》的保护，作品的所有权、版权和著作权归熊猫办公所有，您下载的是PPT模板素材的使用权。 2.不得将熊猫办公的PPT模板、PPT素材，本身用于再出售，或者出租、出借、转让、分销、发布或者作为礼物供他人使用，不得转授权、出卖、转让本协议或者本协议中的权利。 Lesson 89&90 课堂练习 练习一. 单词情景运用。 1.
