Recent scientific studies indicate that eating healthy food and exercising regularly ____ help prevent many diseases.

A. might              B. can              C. shall               D. will      

试题答案

B.

解析： 考查情态动词辨析。can 意为“会，能，能够”，表示一种能力。例如：Even a small personal computer can store vast amounts of information. might“可能”，表示某事发生可能性很小，而shall和will不能表示能力。
