11.Hurry up!The play _______ for half an hour.( 。
A.has been onB.has beganC.has begunD.had begun

分析 快點!演出已經(jīng)開始半個小時了.

解答 答案:A.
根據(jù)for half an hour,可知這里是for引導(dǎo)的一段時間,通常和現(xiàn)在完成時連用,故本句使用用現(xiàn)在完成時態(tài).英語完成時態(tài)中瞬間動詞不能和表示一段時間的時間狀語連用,begin表示瞬間動作,選項BCD都含有begin,排除掉;選項A用be動詞的現(xiàn)在完成時形式,可以延續(xù).故選A.

點評 英語完成時態(tài)中有瞬間動詞與持續(xù)性動詞之分,瞬間動詞只表示瞬間動作,不能和表示一段時間的時間狀語連用,反之持續(xù)性動詞也是一樣.再沒有時間狀語的情況下,就要結(jié)合語境具體分析.
