            • 現(xiàn)在完成時(shí)和現(xiàn)在完成進(jìn)行時(shí)的區(qū)別

              行時(shí)關(guān)注動(dòng)作本身,特別是解釋動(dòng)作可見的結(jié)果時(shí)。 He’s run three miles. (the result: He’s covered the distance of three miles.) He’s been running for an hour. (the activity and its consequences: this is what he’s been doing for the last hour and why he is exhausted now.) 3、現(xiàn)在完成進(jìn)行時(shí)表示重復(fù)的動(dòng)作時(shí),不能同表示具體數(shù)字的詞并用。 I’ve posted a dozen postcards, but received none. I’ve read this book several times. I’ve been posting postcards since early December. 4、現(xiàn)在完成進(jìn)行時(shí)帶有較為強(qiáng)烈的感情色彩。 You have been disturbing me. 5、許多狀態(tài)動(dòng)詞不能用完成進(jìn)現(xiàn)在完成時(shí) 1、表示過去開始并持續(xù)到現(xiàn)在的動(dòng)作。(動(dòng)詞必須是持續(xù)動(dòng)詞) China?has changed a great deal in the past 20 years.? 2、強(qiáng)調(diào)過去動(dòng)作對(duì)現(xiàn)在行時(shí)。 I’ve known that for a long time.? The strike has lasted six months. 6、有少數(shù)動(dòng)詞用兩種時(shí)態(tài)都可以,但若強(qiáng)調(diào)時(shí)間長度時(shí)用完成進(jìn)行時(shí)較好。 They have been working this term. They?have worked very well this term.

              少見她一次? My father has always gone to work by bike.?我父親一向騎車上班。 四、現(xiàn)在完成時(shí)表示將來 同現(xiàn)在完成時(shí)是英語中一個(gè)很重要的時(shí)態(tài),也是很容易弄錯(cuò)的一個(gè)時(shí)態(tài)。歸納起來,現(xiàn)在完成時(shí)共有四種主要用法一般現(xiàn)在時(shí)可以表示將來一樣,現(xiàn)在完成時(shí)也可以在時(shí)間狀語從句里表示將來。如: I’ll wait until he has written his letter.?我愿等到他把信寫完。 When you have rested, I’ll show you the garden.?等你休息好之后,我領(lǐng)你看我們的花園。

              完成進(jìn)行時(shí)由“had been +現(xiàn)在分詞”構(gòu)成。它的用法是表示從過去某一時(shí)在這所學(xué)校教書已經(jīng)10年了. 10.He has done a lot of work in the past two years. since 在現(xiàn)在完成時(shí)中意為自...以后自...以來,時(shí)間狀語常用since加一個(gè)過去的時(shí)間點(diǎn)或for加一段時(shí)間或by加一個(gè)現(xiàn)在時(shí)間。 如果不是時(shí)間點(diǎn) 也不是時(shí)間段 還有什么別的時(shí)間啊 ?具體情況具體對(duì)待吧 最好會(huì)翻譯句子的意思 在適當(dāng)?shù)倪x擇for和since 比如說 1. He has had a house since 2005. ? 他自從2005年以來就擁有了一套房子. ? ? ?? 2. The play cat has been on for half an hour. 短劇《貓》已經(jīng)開演半個(gè)小時(shí)了.
