短暫性動(dòng)詞-延續(xù)性動(dòng)詞和現(xiàn)在完成時(shí)

1、短暫性動(dòng)詞，延續(xù)性動(dòng)詞和現(xiàn)在完成時(shí)延續(xù)性動(dòng)詞是指動(dòng)作發(fā)生后還可以延續(xù)一段時(shí)間或者相當(dāng)長(zhǎng)的一段時(shí)間。如：live,work, study, learn, sleep等，延續(xù)性動(dòng)詞可以和表示一段的時(shí)間狀語連用。短暫性動(dòng)詞是指動(dòng)作一旦發(fā)生就立即結(jié)束。它不能和一段時(shí)間連用。這類動(dòng)詞有：go,come, arrive, leave, begin, start, join, marry等；在否定句中，短暫性動(dòng)詞可以和表示一段時(shí)間的狀語連用。We havent heard from Jane for a long time.短暫性動(dòng)詞的肯定式不能與表示一段時(shí)間的for或since或how long等狀語連用

2、。值得注意的是，表示一段時(shí)間的狀語除了“for+一段時(shí)間”外，還有since+n./從句（時(shí)間點(diǎn)），since+時(shí)間段+ago，疑問詞how long，in the past+時(shí)間段，all these+時(shí)間段，fromto（時(shí)間點(diǎn)）以及till/until+n./句子等等。例如：.I have received his letter for three days（） I have received his letter.（）How long did she leave .（） How long has she been away? ()finish be overput on wear 或b

It is 或者 It has been+時(shí)間+since（動(dòng)詞用過去式），B.主語+謂語（過去時(shí)）+時(shí)間+ago。例如：Its five days since I receive

5、d his letter. His father died three years ago.看一個(gè)句子可以用以下幾種說法：他離開上海已經(jīng)3天了。He left Shanghai three days ago. He has been away from Shanghai for three days/since three days agoIt is/has been three days since he left Shanghai.Three days has passed since he left Shanghai.幾點(diǎn)注意事項(xiàng):（1）have been(to)與have gone(

6、to)的區(qū)別：have been(to)表示“去過某地（現(xiàn)在已經(jīng)回來了）”，可用于各人稱；have gone(to)表示“去某地了（說話時(shí)某人不在當(dāng)?shù)兀?，可能在去的路上，可能已在某地，也可能在回來的路上，總之，人不在這里。常用第三人稱作主語。前者可與once,never, several times等連用，后者則不能。如：They have been to Beijing twice.他們?nèi)ミ^北京兩次。He has gone to Beijing他去北京了。注意比較 has gone to, has been to, has been in的意義：He has gone to Amercia

7、.（他到美國去了。他不在這里）He has been to Amercia.（他去過美國。現(xiàn)已回來）He has been in Shanghai.（他在上海呆過?，F(xiàn)在不在上海）He has been in shanghai for years.（他在上海多年。現(xiàn)在還在上海）（2）終止性動(dòng)詞現(xiàn)在完成時(shí)的否定式，已變成一種可以延續(xù)的狀態(tài)，因此可以和表示一段時(shí)間的狀語連用。如：I haven t left here since 1997.自從1997年以來，我一直沒有離開過這兒。另外，動(dòng)詞的延續(xù)性與非延續(xù)性還體現(xiàn)在這兩種句型中：延續(xù)性動(dòng)詞的肯定式+till/until 短暫性動(dòng)詞的否定式+till

8、/ until請(qǐng)看例句：We waited until he came.I didnt go to bed until my father came back home last night.短暫性動(dòng)詞，延續(xù)性動(dòng)詞和現(xiàn)在完成時(shí)練習(xí)I. 句型轉(zhuǎn)換：1.
