Question

【題目】The concert began about 20 minutes ago. You are late. (改為同義句)

The concert has ______ ______ for about 20 minutes. You are late.

Answer 1

【答案】been on

【解析】

句意：音樂(lè)會(huì)已經(jīng)開(kāi)始20分鐘了，你遲到了。

根據(jù)句意可知音樂(lè)會(huì)已經(jīng)開(kāi)始二十分鐘了，此題考查延續(xù)性動(dòng)詞和非延續(xù)性動(dòng)詞之間的區(qū)別，在現(xiàn)在完成時(shí)的句子中如果出現(xiàn)for+時(shí)間需要將短暫性/非延續(xù)性動(dòng)詞換為延續(xù)性動(dòng)詞，故將began改為have been on +一段時(shí)間。故填been on。
