爱华网情态动词，顾名思义是可以表达情感和态度的一组动词。我们从初中就开始接触情态动词，但你真的了解情态动词的用法吗?
May表示“许可、准许”。例如：You may enjoy the buffet provided by competition organizer.(你可以享用由赛事主办方提供的自助餐。)
May也可以表示“可能、也许”。例如：I may have forgotten to keep you updated about the new decisions made by the board. (我可能忘记告诉你董事会的最新决定了。)
Should亦有许多意思。可以表示“应该、应该”。例如：You should have given me a heads up warning me the teacher was around.(你本应该提醒我一下老师就在附近。)
Should也可以用作猜测，意为“可能，大概”。例如：She should be exhausted to death after all the travelling.(经过这番旅行，她肯定累死了。)
Should最高级的用法，就是它作为“万一、竟然”解释的时候了。说它高级是因为不仅牵扯到情态动词，还有相关虚拟语气的知识需要了解。例如：If she should betray us and claim all the credits for herself, I would have to reveal all the hidden truth that people don’t know.(如果她背叛我们，宣称功劳都是她自己的，那我不得不公开不为人知的事实。)
Would作为情态动词最基本的意思是表达意愿，意为“愿意，要”。例如：I told her a million times that he is a player, but she just wouldn’t listen. No wonder she was hurt so badly this time.(我告诉她一万遍了那个男孩是个花花公子，她就是不听。这次她不难过才怪呢。)
Would也有一个大家不熟悉的用法，意为“过去常常……”。例如：I remember during the first several months after grandmother’s passing away, my mother would stare at our family photo for hours.(我记得外婆去世的头几个月里，妈妈常常盯着我们的全家福看，一看就是几小时。)
以上讲解的情态动词用法不尽完全，但是情态动词的共性却显露无疑。通过例句的分析，你是不是也有更深入的了解了呢?
