关于英语完成时的几个问题
1.—How long has the film KING KONG been on?
—For just several minutes.(为什么用been on这里不能begun）
2.—The Blacks have gone to the Phoenix Island.
—Oh,really?I have never been there before.(为什么用been不用been to)
3.—Do you know Huang Ting well?
—Yes.She and i have been friends since we met in Wuhan last summer.
(这里为什么不用had been而用have been?)
4.He has been away from our school for two weeks.(这句话为什么不用has left而用has been away from?)
5.A:What's wrong with your uncle,Jack?
B:He is ill.A doctor has just been sent for.为什么 has just been sent for出现了been 和sent两个过去分词）
6.What are you goin to do this Saturday?
I haven't decided yet.从哪里看出来要用到现在完成时啊?）

1 begin 是瞬间动词不能表状态,how long 表示一段时间 要用连续动词
2 there这里是副词,没必要用介词
3 since...表示从去年夏天一直到现在的时间里,所以用现在完成时
4 leave 是瞬间动词不能表状态,后面不能接时间段 只能用表状态的动词,be away from
5 这里是被动 send for a doctor 请医生 医生已经被人取请了
6 你周六准备/打算做什么?我还没有确定 （过去一段时间延续到现在,我都没确定）
