終止性動(dòng)詞不與一段時(shí)間狀語(yǔ)連用

■由于終止性動(dòng)詞發(fā)生或存在的時(shí)間很短，有時(shí)甚至只是一個(gè)概念，因此它不能與一段時(shí)間連用。如：

他參軍10年了。

誤：He joined [went into] the army for ten years.

正：He joined [went into] the army ten years ago.

正：He has been in the army for ten years.

正：He has been a soldier for ten years.

終止性動(dòng)詞如come, go, join, leave, buy, see, finish, hear, appear, die等。

一段時(shí)間如five minutes, half an hour, three days, one week, two years等。

■偶爾見(jiàn)到終止性動(dòng)詞與一段時(shí)間連用，那么它表示的一定是指終止性動(dòng)詞所表示的動(dòng)作結(jié)束后所持續(xù)的一段時(shí)間，如：

He has come here for a week. 他已來(lái)了，準(zhǔn)備呆一個(gè)星期。

若要表示“他已來(lái)了一個(gè)星期”，則說(shuō)：

He has been here for a week. / It is a week since he came.
