現在完成時(shí)中瞬間動(dòng)詞和和延續性動(dòng)詞的轉換
現在完成時(shí)有一個(gè)用法表示動(dòng)作從過(guò)去開(kāi)始,一直持續到現在,且可能繼續,這時(shí)候要和表示時(shí)間段的時(shí)間狀語(yǔ)連用,因此相應的動(dòng)詞也需要使用延續性動(dòng)詞。
例:
①I(mǎi) have bought this book for two weeks. ×
I have had this book for two weeks. √
注:因為買(mǎi)(buy)這個(gè)動(dòng)詞是瞬間動(dòng)詞,因此與for two weeks這個(gè)時(shí)間段連用的時(shí)候需要轉換成延續性動(dòng)詞have。
②( )The train for a long time.
has left B. has away C. has been away D. left
解題思路:時(shí)間標志詞for用于現在完成時(shí),先排除D,現在完成時(shí)謂語(yǔ)結構是have(has)+動(dòng)詞過(guò)去分詞,排除B,因為時(shí)間狀語(yǔ)是時(shí)間段,所以動(dòng)詞需要有延續性,故選C。
答案:C
※常見(jiàn)的瞬間動(dòng)詞與延續性動(dòng)詞的相互轉換:
borrow → keep buy → have
leave → be away marry → be married
die → be dead finish → be over
join → be a member of begin/start → be on
open → be open close → be closed
