26、ell, lose, kill等，這些動詞不能和表示一段時間的時間狀語連用。 但是，非延續(xù)性動詞的否定形式可以表示狀態(tài)的延續(xù)，可與for/since等時間狀語連用。 第37頁/共62頁 有些同學錯誤地認為這類非延續(xù)性動詞不能用于完成時態(tài)中。其實，錯誤的本質(zhì)在于非延續(xù)性動詞與時間段的錯誤搭配，與現(xiàn)在完成時態(tài)無關。第38頁/共62頁延續(xù)性語境中的非延續(xù)性動詞的使用延續(xù)性語境中的非延續(xù)性動詞的使用 在具體的語言環(huán)境中，往往會出現(xiàn)非延續(xù)性動詞與時間段相連用的情況。由于受漢語影響，往往錯誤地直譯為：He has fallen asleep for an hour.他睡了一小時了。（）His father

27、 has died for three years.他父親去世三年了。（）當出現(xiàn)這種情況時，我們往往采取以下解決方法：第39頁/共62頁（1）將非延續(xù)性動詞轉(zhuǎn)化為相應的狀態(tài)動詞。所謂狀態(tài)動詞就是指這一動作發(fā)生后接下來所呈現(xiàn)的狀態(tài)。如： He has been asleep for an hour. （fall asleep,“入睡”為短暫動作，但be asleep“睡著”則為狀態(tài)動詞，可延續(xù)。） His father has been dead for three years.（die為短暫動詞，“死”后的狀態(tài)可用“be dead”這種系表結構來描述，可延續(xù)。）第40頁/共62頁常見的這種動詞

28、的轉(zhuǎn)化有以下幾類：常見的這種動詞的轉(zhuǎn)化有以下幾類： go therebe there, come backbe back, borrowkeep, buy/catchhave, arrivebe in, beginbe on, openbe open, closebe closed, diebe dead, leavebe away from, get upbe up, fall asleepbe asleep, becomebe, joinbe in/a member of, receivehave, catch/get a coldhave a cold, get marriedbe ma
