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
解释：
1、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,因此不用been on.
2、而且been on 通常与【一段时间】连用,比如：The film has been on for 5 minutes.
这部电影已经开始5分钟了.
句意：当我到电影院的时候,电影已经开始了.

因为没有说开始多长时间了，所以这两个答案都是正确的

选A，通常情况下应该是的。

A been on 已经开始了
不能用 begun 因为begin (begun)是暂短性动词
