Using verbs + to-infinitives
当我们要表示“想做某事、需要做某事 或决定做某事”时，就会出现两个动词 连用的情况，这时应如何表达呢？ 同学们自然会想到want to do sth., need to do sth.和decide to do sth. 等表达方式。
Please go on to look at the sentences below. Pay attention to the colored words.
1. 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”。 2. 当句子中已经有谓语动词，而我们又要 表达不止一个动作概念时，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，其肯定形 式是“to + 动词原形”，其否定形式是 “not to + 动词原形”。无人称、数和时 态的变化。
3. — Excuse me, when are we going to have a picnic? — I’m not sure, Ask our monitor, please. He ______ know. A. need B. can C. may D. shall 4. — Do you have any plans for this weekend? — I'm not sure. I ______ go climbing Mount Yuntai. A. must B. need C. may D. can
什么是动词不定式 (‘to-infinitives’)？
上面例子中主要行为动词后面的动词 都采用了“to + 动词原形”的结构，我 们把这种结构称为动词不定式（有时 可以不带to）。动词不定式没有人称 和数的变化，在句子中不能单独作谓 语，其否定形式是“not to + 动词原形”。
