顺口溜：本领最多不定式，主表定补宾和状；样样成分都能干，只有谓语它不敢；大家千万要小心，有时它把句型改；作主语时用it，自己在后把身藏；七个感官三使役，宾补要把to甩开；疑问词后接上它，宾语从句可充当；逻辑主语不定式，不定式前加for sb.；to前not是否定，各种用法区别开。
以下是不带to的动词不定式(即动词原形)的常见用法
★ let sb. do sth让某人做某事 ★ make do sth使得某人做某事
★ hear do sth do sth听见某人做某事 ★see do sth do sth看见某人做某事

例:Why not/Why don’t you take a walk?
★ 某人+had better( not)do 某人最好(不)做某事
★ 情态动词can/may /must /should+ 动词原形（包括情态动词的否定形式+动词原形）
★ 助动词do/does/did/will/would在构成疑问句或者构成否定句即don’t /doesn’t /didn’t /will not /would not+ 动词原形
★ be going to + 动词原形（表示“即将”“打算” 做某事）
