A．a friend should be made known of his difficult situation

B．a man should be equipped with the kind of knowledge required

C．nothing is better than offering of knowledge required

D．keeping one’s promises is most important

Answer 1

B

考查不定式的用法，这里不定式做目的状语，不定式的逻辑主语应该和主句的逻辑主语一致，这题结合句意应该是a man，句意是：为了帮助朋友解决困扰他的问题，一个人应该具备需要的这种知识。选B。
