课本原句:If we want to keep up with the high pace of modern life, we had better learn to make the right choices about what and how we eat.
知识要点:had better“最好”,是情态动词,后跟动词原形,指现在或将来的时间,不指过去。它没有人称、时态和数的变化,否定形式是had better not do sth.。

A. had better to *B. had better
C. would better D. would better to
点拨:从“外面寒冷”可知“穿上大衣”是一种建议,所以选B。
