Question

-We've got everything  ready for the picnic．
-Do you mean I______bring anything with me？（　　）

A. can't

B. mustn't

C. couldn't

D. needn't

Answer 1

答案：D．
can't不可能；mustn't不可以；couldn't不可能；needn't不必．在请求语句里面couldn't比can't较委婉，can't表示推测时，意思是"不可能…"，语气非常坚决的否定推测．根据We've got everything  ready for the picnic，可知我们已经准备好了野餐的一切了，所以你不必带任何东西了．needn't不必．故选D．
