英語動詞根據詞義可分為兩種,一種是延續性的,一種是終止性的,終止性動詞(也可稱為非延續性動詞,瞬間動詞,或點動詞),如begin,start,die,buy,leave, come等,表示動作的發生與結束於一瞬間完成,不能再延續,所以它的現在完成時不能和表示延續的時間狀語連用,即不能與表示一段時間的狀語,for+時間段, since+時間點/從句連用,也不能用在how long引導的特殊疑問句中.
eg. I've left Shanghai for three days.(×) I've been away from Shanghai for three days.( √ ).
I left Shanghai three days ago. ( √ ) It is /has been three days since I left Shanghai.( √ )
常見終止性動詞有:leave, go, come, arrive, begin, buy, borrow, die, join, become等.終止性動詞要表示持續時, 可用以下方法:
⑴.將時間狀語改為時間段 + ago,句中謂語動詞用一般過去時.
eg.我弟弟參軍兩年了. My brother joined the army two years ago.
⑵.若保留for+時間段,since+時間點/從句, 或用在 how long 句型中,則需將終止性動詞改為相應的狀態動詞或延續性動詞
常見終止性動詞與延續性動詞(或狀態動詞)的對應關係如下
come/go/arrive/get/reach/move------be in/at open-----be open
die------be dead close----be closed become---be borrow---keep begin/start-----be on put on----wear
