—Need I accomplish all we have set out to do?
—Yes, you ____; otherwise you ____fired.

A．need; would have beenB．may; need have been
C．can; mustn't have beenD．must; would be

D

解析試題分析：考查情態(tài)動詞和虛擬語氣。句義：我需要把握所做的所有事情都完成嗎？是的，必須完成，否則你會被解雇的。Need開頭的疑問句的肯定回答：yes，you must,否定回答：No,you needn’t；otherwise="if" you didn’t pccomplish …,是對將來的虛擬，所以主句應(yīng)為：would  do ,所以D正確。
考點：考查情態(tài)動詞和虛擬語氣。
