12、foranhour. ThechildrenhavebeenwatchingTVsincesixoclock.现在完成时概念：过去发生或已经完成的动作对现在造成的影响或结果，或从过去已经开始，持续到现在的动作或状态。初二上册Unit5中的英英解释：We use the present perfect tense to talk about things that happened in the past but have a connection to the present in some way. 发生在过去的事情 和现在有联系需要与之作出最大区分的一个时态就是 过去时过去时表示过去的一个

13、动作，而且通常含有“过去时，而现在不是的”的含义。比如，我以前是一名学生。我以前是做翻译的。I was a student. I was a translator. 这种用一般过去时表示的就是以前是怎么的，但是现在已经不是了。现在完成时表示过去的动作持续到现在，以前是这样，现在还是这样。还可以表示过去的动作对现在造成的影响。I have had lunch. 我吃过午餐了，隐含意思现在不饿；I have watered the flowers. 我已经浇过花了，隐含意思你不需要再浇水了。再次对比过去时和完成时所表达的意思I have watered the flowers.我已经浇过花了。 不

16、我从来都没有见过这种鸟。Have you ever visited the Summer Palace? 你参观过颐和园吗。He has been in Beijing for ten years. 他已经在北京呆了10年了。Ben has never slept since last night.

20、只能与表示不定的过去时间状语(如：already，yet，before，recently等)、频度时间状语(如：never，ever，once等)、包括现在时刻在内的时间状语(如：thismorningmonthyear.，today等)连用。例如：Haveyoufoundyourpenyet？你已找到你的钢笔了吗？2.现在完成时的未完成用法现在完成时的未完成用法指的是动作开始于过去某一时刻，一直延续到现在，或可能还要继续下去。例如：Hehaslivedheresince1978.自从1978年以来，他一直住在这儿。(动作起始于1978年，一直住到现在，可能还要继续住下去。)Ihavebeen

21、inthearmyformorethan5years.我在部队已经呆了五年多了。(动作开始于5年前，一直延续至今，有可能还要继续下去。)此种用法的句中常需一个表示一段时间的状语(由since或for引导)，或表示与现在时刻相连的时间状语(如：uptonow，sofar到目前为止)等。例如：Ihaveheardnothingfromhimuptonow.到目前为止我没有他的任何消息。注意：现在完成时的未完成用法只适用于延续性动词，不可用于终止性动词，即瞬间完成或延续时间很短的动词。3.延续性动词和瞬间性动词的概念英语中，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瞬间性动词。延

22、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。如：learn,work,stand,lie,know,walk,keep,have,wait,watch,sing,read,sleep,live,stay等。瞬间性动词也称非延续性动词、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。如open,close,finish,begin,come,go,arrive,reach,getto,leave,move,borrow,buy等。Itrainedateightyesterdaymorning.(误)rain为延续性动词，而ateight表示点时间。上句可改为

23、：Itbegantorainateightyesterdaymorning.(正)I have borrowed the book for 2 months.（误）borrow是“借”不能做借这个动作做了2个月吧I have kept the book for 2months.（正）换成keep这个动词，保持，借到手了就拿了2个月-WhendidyougettoknowJack?-Twoyearsago.-Thenyouveknowneachotherformorethantwoyears.-Thatsright.附加延迟动词与瞬间动词转换表（部分）：注意be的作用很大瞬间动词延续动词瞬间动词
