情态动词may的用法
当我们猜测某件事发生的可能性时，常用may来表示“也许”、“可能”。如：
You may be right. 你可能是对的。
He is away on business. He may not come to the party this evening. 他出差了，可能不会来参加今天晚上的聚会。
注意：may表示“可能”时，通常只用于肯定句和否定句中，相当于possibly、perhaps或者maybe
动词不定式作宾语
当句子中已经有谓语动词，而我们又要表达不止一个动作的概念时，其余的动词可以使用非谓语形式表达。动词不定式就是动词的一种非谓语形式，其基本形式是“to + 动词原形”。如：
He wants to play football after class. 他想课后踢足球。
My mother forgot to turn off the lights yesterday.
我妈妈昨天忘记关灯了。
注意：动词不定式在句中不作谓语，因此没有人称、数和时态的变化。
动词不定式在句中常作谓语动词的宾语，这一类谓语动词常见的有：
agree (同意) choose (选择) decide (决定) forget (忘记)
hope (希望) learn (学习) like (喜欢) plan (计划)
prepare (准备) promise (答应) refuse (拒绝) remember (记得)
seem (觉得好像) want (想要) wish (希望) would like (想要)
I decided to visit my grandparents this weekend.
我决定这个周末去看望我的祖父。
注意：动词不定式的否定形式是“not to + 动词原形”。如：
You must promise not to be late again. 你必须保证不再迟到了。
