句子强调的是all morning,所以应该表示工作这个持续的状态,要用been working.have worken表示的是动作．

因为这里是现在完成进行时表示一直在进行的动作，时间状语all morning可以表明是一早上都在做的事情

用 have been working 的原因是为了表示我还会继续进行做了一个早上还未做完的工作，用了present perfect continuous tense(即have been working)去表示之后还会继续这个工作，但present perfect tense（即have worked)就没有这意思。

I have been selling I have been trying I have ever been I too have been I have been to. I have been I have been in. I have been there,have been 是have been in还是have been to的缩写? 关于时态的问题have beenhave been 和have had been有什么区别?原句是这样的：I've heard has been good.有have也有has 关于Have you been Have you ever been to Peking?yes,i have been there -----Athree timesBfor three timesCfor two months(我主要想问c为什么不对) i have always been there i have never been there I HAVE NEVER BEEN,能否说I never have been I have been so serious I have been so serious I-have-been-at-home I have always been you I have been loving you I have been a person . I have never been away!
