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：

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。
afford agree choose decide expect forget hope
learn manage like offer plan prepare promise
refuse remember try want wish
