The elderly ______ good care of in public places like supermarkets and airports; they are likely to get lost.

A．can have been taken

B．ought to be taking

C．must be taken

D．should take

答案

C

解析

词义辨析。主语The elderly和take good care of是动宾关系，要用被动形式，排除B,D；can have been taken，可能已经被照顾；must be taken必须被照顾。句意：老人在公共场所，例如超市和机场，必须被好好照顾；他们很可能会迷路。所以选C。
