had better,should,ought to 含义及语气有所不同,请看下表:

二、should和ought to均为提建议型情态动词,可表示“责任”、“义务”,常用来劝告别人去做某事,译为“应该”,还勇于纠正某人的错误。 其特点是:和另一个动词共同构成谓语,没有人称和数的变化,后接动词原形可以表示现在、将来或过去将来,由时间状语或上下文决定。

例如: We ought to be more careful with our homework.


You should follow Mr. Wang’s advice. 你应当听王老师的话。

she should be back tomorrow.它应该明天回来。

I ought to do my homework now.我应该现在就做作业。

What’s wrong with my answer? It should be 62,not 26.
