现在完成时中非延续性动词的转换 现在完成时表示过去发生的某一动作或存在的状态,一直持续到现在,并可以和以for或since引导的表示一段时间的状语连用,也可以用在以“how long”提问的句子中,句子中的谓语动词一般为延续性动词。但是,有些动词所表示的动作是短暂的,这类动词叫做非延续性动词。如:come, go, reach, arrive, leave, borrow, buy, join, die, begin, start, finish等。在现在完成时的句子中,非延续性动词作谓语动词时,不能和表示一段时间的状语连用。 表示动作的连续性,就要把非延续性动词转换成相应的延续性动词或短语,具体转换如下:(要求记住)come/go/reach/arrivebe in/at, leavebe away from, borrowkeep, buyhave, joinbe in/be a member of, diebe dead, start/beginbe on, finish/endbe over, openbe open (adj.), closebe closed (adj.), marrybe married come to / go back to / return to be back to go out be out become be get up be up; die be dead; fall asleep / get tot sleep be asleep; lose not have ; put on wear catch / get a cold have a cold; get to know know have / has gone to have been in 注意: 1. 非延续性动词可以在现在完成时的否定句中作谓语,并可以与for,since引导的时间状语连用,表示动作的延续过程。例如: She hasnt bought any new clothes since last year. 2. 在现在完成时的肯定句中,非延续性动词作谓语时不能与for,since引导的表示一段时间的状语连用,但可以用其他句式来表示同一个意思。例如:例:The old man died 4 years ago. -The old man has been dead for 4 years. - It is 4 years since the old man died. -Four years has passed since the old man died. He joined the Party 2 years ago. -He has been in the Party for 2 years. I bought the book 5 days ago. - I have had the book for 5 days.

They have bought a computer. (改成否定句)_5. He has lost his book.(先改成一般疑问句,再作肯定与否定回答)_C) 单项选择6. -Where have you _, Kate? -Ive _ to the bank.A. gone, goneB. been, beenC. gone, beenD. been, gone7.
