終止性動詞不與一段時間狀語連用

■由于終止性動詞發(fā)生或存在的時間很短，有時甚至只是一個概念，因此它不能與一段時間連用。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.

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

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

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

He has come here for a week. 他已來了，準備呆一個星期。

若要表示“他已來了一個星期”，則說：

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