选择题
—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
答案
答案：A
句意：——为了我们年迈的父母，你认为我们可以做些什么事呢？——你不必做任何事情，只要能真情地陪伴他们。don't have to＝needn't表示“不必”，符合语境。oughtn't to＝shouldn't不应该；mustn't不可以，禁止做；can't不能，均不合句意。
