D. 电影已经开始5分钟了 翻译
The film has been on for 5 minutes
E. 翻译:电影开始多久了
How long has the movie begun?
The Blakes leave China since three years ago.
Has David left the key in the classroom?
F. 当我们到达电影院时，电影已经开始二十分钟了怎么翻译啊
当我们到达电影院时，电影已经开始二十分钟了？When we arrived at the cinema, the film had begun to 20 minutes?
G. 电影已经开始多久约十分钟。翻译英文
how long has the film been on? About 10 minutes.注意start这样的非延续动词不能用于完成时，也不会和how long 搭
H. 当我们到达电影院时，电影已开始二十分钟了（翻译成英语）
翻译如下：
当我们到达电影院时，电影已开始二十分钟了
When we arrived at the cinema, the film had already been on for twenty minutes
要日文还是英文？
英文：What time does the film begin?
日文：この映画は何时に始まりますか？
J. 英语问题电影开始多久了
是要翻译这句话吗？
How long has the movie been on?
这里要注意，容易把句子错写成:how long has the movie started/begun?因为start和begin都是瞬间动词，是不能持续一段时间的，所以也就不能用how long来提问。
而be on指的是电影上映了、开始了的状态，状态是可持续的
