The film had ______when I got to the cinema.A been on B.begun

The film had ______when I got to the cinema.A been on B.begun
The film had ______when I got to the cinema.A been on B.begun

The film had ______when I got to the cinema.A been on B.begun
答案：B
be on 表示“上映,演出”,是延续性动词,而begin是瞬间动词,而后面的“when I got to the cinema”决定了答案只能是B,也就是当我到达电影院的这个时刻,电影已经开始,所以不要been on.而且been on 通常与一段时间连用,比如：The film has been on for two hours.（电影放了2个小时.）
句意：当我到电影院的时候,电影已经开始了.
