( ) 2 His father has died since he was five years old . ( )have been inhas been dead 瞬間動詞的用法口訣;現(xiàn)在完成在瞬間,非延只連時間點, 終止 須轉(zhuǎn)換,否定方可碰一段說明:1 瞬間動詞又叫非延
7、續(xù)性動詞或終止性動詞,它可以有現(xiàn)在完成時態(tài),但不可以接一段時間;如果要接一段時間,就必須把它轉(zhuǎn)換成相應(yīng)的延續(xù)性動詞。2 瞬間動詞在完成時態(tài)中的否定式中可以接一段時間。 類似的轉(zhuǎn)換還有:fall asleepbe asleep move therebe there open be open 等 巧記巧記10個瞬間性動詞的轉(zhuǎn)換個瞬間性動詞的轉(zhuǎn)換 “開始離去借來還,出生入死買到家開始離去借來還,出生入死買到家”1 beginbe on6 returnbe back2 leavebe away from7 joinbe in3 gobe off8 diebe dead4 borrowkeep9 buy
