8、. _ 3 years ago. _ we _(come)here,for,since,came,_,How long have you learnt English?,for + 一段時間 since + 過去的時間點/句子 就畫線提問用how long,since,Step 二、 for 用法 1、當(dāng)我們談?wù)撘欢螘r間時用for ,談?wù)撨^去時間點用 since 1).Mr Dong has lived here for many years . 2).Mr Dong has lived here since he was born . 2、一些動詞如come ,go, leave ,但它們在

He has not bought any car since 2007 . 6. He has had a car since 2007 . 3、 for 和 since 的用法及區(qū)別 1. since 的四種用法 1).since + 過去一個時

10、間點（如具體的年、月、日期、鐘點、 eg. 1990 , last month , half past six I have been here since 1990. 1990起，我一直在這兒。 2). since+ 一段時間+ago I have been here since five months ago. 自從五個月前，我已經(jīng)在這兒了。,3).since+從句 Great changes have taken place since you left. 自從你走后，已經(jīng)發(fā)生了很大的變化。 4).It is +一段時間+since 從句 It is two years since I

I have been here for 3 days. (對)

12、 I have arrived here for 3 days.（誤） 5、延續(xù)性動詞和終止性動詞 英語中，動詞按其動作發(fā)生的方式、動作發(fā)生過程的長短，可分為延續(xù)性動詞和終止性動詞。 1),延續(xù)性動詞表示能夠延續(xù)的動作，這種動作可以延續(xù)下去或產(chǎn)生持久影響。如：learn, work, stand, lie, know, walk, keep, have, wait, watch, sing, read, sleep, live, stay等,2),終止性動詞也稱非延續(xù)性動詞、瞬間動詞或短暫性動詞，表示不能延續(xù)的動作，這種動作發(fā)生后立即結(jié)束。如open, close, finish, begin

13、, come, go, arrive, reach, get to, leave, move, borrow, buy等。 6、延續(xù)性動詞的用法特征 1).延續(xù)性動詞可以用于現(xiàn)在完成時，其完成時態(tài)可與表示“段時間”的狀語連用。表示“段時間”的短語有：for two years, during the past three years, since last year, how long等。 如：I have learned English since I came here.自從我來到這兒就學(xué)英語了。,2),延續(xù)性動詞不能與表示短暫時間的“點時間”狀語連用。如： It raind at eig

14、ht yesterday morning.(誤) rain為延續(xù)性動詞，而at eight表示點時間，前后顯然矛盾。如果用延續(xù)性動詞表示一瞬間的動作，可以借助come, begin, get等終止性動詞來表示。上句可改為：It began to rain at eight yesterday morning.(正)又如：,-When did you get to know Jack? -Two years ago. -Then youve known each other for more than two years. -Thats right. 7.終止性動詞的用法特征 1).終止性動詞可

15、用來表示某一動作完成，因此可用于現(xiàn)在完成時。如： The train has arrived.火車到了。 Have you joined the computer group?你加入電腦小組了嗎？ 2).終止性動詞表示的動作極其短暫，不能持續(xù)。因此，不可與表示一段時間的狀語連用(只限肯定式)。如：,(1)他死了三年了。 誤：He has died for three years. 正：He has been dead for three years. 正：He died three years ago. 正：It is three years since he died. 正：Three ye

16、ars has passed since he died. (2)他來這兒五天了。 誤：He has come here for five days. 正：He has been here for five days. 正：He came here five days ago. 正：It is five days since he came here. 正：Five days has passed since he came here.,Step 三 常見的非延續(xù)性動詞與延續(xù)性動詞的轉(zhuǎn)換。,buy have go out be out leave be away begin/start be

17、on come/go be in/at borrow keep join be a member of/be in die be dead catch a cold have a cold become be fall asleep be asleep open be open get to know know close-be closed arrive-be in/at get married-be married fall illbe ill get upbe up catch a coldhave a cold,例子： 1.I have borrowed the book for 2
