I have been working hard all morning 我辛苦工作了一个上午为什么要使用动名词working have+been算复合谓语吗？复合谓语好像是have+be（原形的）这边为什么要使用后置定语hard来 而不是 hard working?

I/we should have been working.是什么意思 I have been working for two days. i have been working lots as Because i have been working Because i have been working hard I have been working here for 7 years.改为同义句怎摸说形如I have been working here— — — I have been working hard all morning有没有什么语法错误有have been working这种说法吗 have been working 是什么时态 I so busily recently that I ____nnnno time to help you with your math .- I can manage it by myselfA.have been working;have B.have worked; had C.am working; will have D.had been working ;had had I am a man so I will have been working and never give up谁说的 I worked all I have been working all day 这两句有什么区别么 where have you been?we have been looking for you everywhere.i(worked out)a teaching plan in my office.为什么这里不填have been working out.had been working out; had been work out I have been working for more ten years.这里的for是否可以去掉呢 by this time next week ,i will have been working for this firm for twenty years 英语翻译I have been a working writer for most of my life Have been working for several years I have been working for an hour. I have working for an hour. 这两句话都正确吗?意思是否相同?错的话怎么改? have you been working as a clerkHave you been working as a clerk?--_ .I am a lawyer now.A.Yes,I do.B.Yes,I have.C.No,I haven’t D.No,I don’t I ___ on my report next week so I won’t be able to meet you any day.A.am working B.will be working C.was working D.have been working顺便翻译下
