9、。另外，ago不能用于現(xiàn)在完成時的句子里，因為它表示從現(xiàn)在算起的以前某個時間，屬于表示具體過去時間的狀語。但是可以用before來表示以前的意義，因為它只表示以前，而不知什么時候的以前。 C. 如果是不表示連續(xù)性的動詞用于現(xiàn)在完成時的句子，不可以和以for表示的一段時間的狀語連用。在這種情況下，應(yīng)該用It has been since的句式來表達。如： He has joined the army for five years. （錯誤） It has been five years since he joined the army. （正確）現(xiàn)在完成時 關(guān)于現(xiàn)在完成時的時間狀語問題: B.
