Question

—What do you think we can do for our aged parents?

—You ___ do anything except to be with them and be yourself.

A.don’t have to                                         B.oughtn’t to

C.mustn’t                                                        D.can’t

Answer 1

A

解析:

don’t have to意为“不必”。根据所提供的情景“except to be with them and be yourself”可判断出除了和他们在一起表现好不必做其他任何事。oughtn’t to 意为“不应该”；mustn’t 意为“不准,禁止”；can’t 意为“不能够,不可能”。
