顺口溜：掌握多种技能的不定式，主语、表语、定语、补语和状语都能胜任；各种句子成分都能充当，唯独谓语不敢越雷池一步；使用时需格外谨慎，有时它会改变句子结构；作主语时用it作形式主语，自身置于句后隐藏；七个感官动词和三个使役动词，宾语补足语要省略to；疑问词后直接跟它，宾语从句可充当；逻辑主语不定式前加for sb.; to前加not表示否定，各种用法需严格区分。
以下是不带to的动词不定式(即动词原形)的常见用法
★允许某人做某事allow sb. to do sth 让某人做某事 ★促使某人做某事prompt sb. to do sth

★建议采取某种行动why not/why don’t you +动原？为什么不.?Why not/Why don’t you go for a walk?
★建议某人最好(不)做某事It is advisable for sb. (not) to do sth.
★情态动词can/may /must /should+ 动词原（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
★ 表达未来计划+ 动词原形（表示“即将”“打算” 做某事）
