1. 翻译：当我到了电影院时，电影已经开始了。
(By) (the) (time) I got to the cinema,the movie (had) (started).
后面必须用 过去完成时，才能体现比我到达的时间更早，（主句谓语用了过去式 got).
2. 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?
3. 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
4. 电影已经开始10分钟了，我们最好现在走吧，不能再等了 英语翻译
We'd better go now, because the movie has begun for ten minutes.We have no time to waste.
5. 电影已经开始5分钟了，用英文怎么说(选择题)
本题选C。
从本题的时态及时间状语（for 5 minutes）来判断，这是一道考现在完成时表示动作持续时，动词要用持续性动词的选择题。四个答案当中，D有明显错误（begin的过去分词是begun而不是began）。答案A和B中的动词分别为begin 和start。这两个都是短暂动词。只有答案C中用了be on （表示“（娱乐演出等）上演；进行中”），这个状态可以持续。所以选C。
又比如：
He has died for two years. (wrong)
He has been dead for two years.(right)
He has left for five minutes.(wrong)
He has been away for five minutes. (right)
6. 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
7. "这部电影已经开始半小时了"英文怎么说
This film has been on for half an hour.
This film started half an hour ago
