Question

【題目】The film _______ for half an hour when I got to the cinema yesterday.

A. has begun B. has been on C. had begun D. had been on

Answer 1

【答案】D

【解析】句意：昨天我到電影院時(shí)，電影已經(jīng)開(kāi)始了半個(gè)小時(shí)了。For+時(shí)間，做某事做了多長(zhǎng)時(shí)間，后面跟延續(xù)性動(dòng)詞，begin（開(kāi)始）是瞬間動(dòng)詞，be on（開(kāi)始）是延續(xù)性動(dòng)詞，一般用于完成時(shí)態(tài)（現(xiàn)在完成時(shí)或過(guò)去完成時(shí)），根據(jù)從句是過(guò)去式可知主句用過(guò)去完成時(shí)，結(jié)合句意和語(yǔ)境可知選D。
