which shoule be choose Why?

you must be very tired.You___like this for days.A work B worked C will work D have been workingwhich shoule be choose Why?
选D
因为该句后面有表示时间段的时间状语for days,译为：这些天,表示动作一直持续,而且目前仍在进行,所以用现在完成进行时,故选D .
以后再做此类题时,要特别注意句子的时间状语.

chooseD
for days indicates that this acition continues into the present,and maybe into the future.

D have been working
强调一直在工作，所以累了。
祝你进步

D no reason,no why

D,后面有for days

D 前一个句子说非常累，后面就要说一直在这样工作，因为D是现在完成进行时，所以强调的是一直做同样一个动作一直到现在，所以才造成了很累。
