Question

【題目】Why are you so late? The parade __________ for half an hour.

A. has begunB. has beenC. has been onD. began

Answer 1

【答案】C

【解析】

句意：你為什么這么晚？游行已經(jīng)開(kāi)始半個(gè)小時(shí)了。has begun已經(jīng)開(kāi)始；has been一直是；has been on已經(jīng)進(jìn)行；began開(kāi)始，過(guò)去式。根據(jù)句意可知，這里強(qiáng)調(diào)過(guò)去發(fā)生的事情對(duì)現(xiàn)在的影響，應(yīng)用現(xiàn)在完成時(shí)，排除D。句中for half an hour表示一段時(shí)間，begin是瞬間性動(dòng)詞，不能和一段時(shí)間狀語(yǔ)搭配，故應(yīng)選C。
