Question

The film had been on for ten minutes when i got to the cinema.

The film had been on for ten minutes when i got to the cinema.当我到电影院的时候 电影已经开始十分钟..had been on 为什么不是had been。而是had been on 。
thanks a lot！

Answer 1

been是系动词,后面必须加表语.而这个on正是表示“开演”的意思.
It's my pleasure.

Answer 2

on 既是 ongoing 的意思， 若是用 had been 而不是had been on 的话， 读不通啊。

Answer 3

had been什么？
在上演啊，所以用had been on

Answer 4

on 和 had been 不是一起用的
had been on 是在说电影已经开始
on这里是开始的意思
had been这里是已经的意思

追问

为什么不接begining 而是on，on也不代表开始啊，它只是个介词啊。

追答

on 在这里像turn on (打开）, 中的on是开，on 要看你用在哪里
beginning 是开端，开头的意思，也是开始但要看情况。
The movie is beginning. beginning 在这里是动词
电影要开始了。
the beginning of the movie.
电影的开头。
