Infinitive 不定式
动词不定式的基本形式是“t + 动词原形”。动词不定式没有人称和数的变化，在句子中不能作谓语。动词不定式仍保留动词的语义特点，可以有自己的宾语和状语。动词不定式同它的宾语或状语构成不定式短语，如 t make new friends、t reach the tp much faster等。
动词不定式具有名词、形容词和副词的特征，因此在句中可作主语、宾语、宾语补足语、定语、状语和表语等。
用it作形式主语，把真正的主语动词不定式置于句后。
常用动词不定式短语作宾语的动词有：want、lve、begin、need、learn、agree、decide、hpe、start、refuse等。
动词不定式作定语，要放在它所修饰的名词或代词后面
tell、ask、want、invite等动词后常跟动词不定式作宾语补足语。
用在t … t … 结构中，作结果状语
用在作表语的形容词或过去分词之后，作原因状语
“疑问词+不定式” 结构

A review f the infinitive
t加动原，用法很多面，否定nt加在前；名、形、副角色，句中灵活变；特殊动词省略t，使役感官要记牢。
D yu remember?
作主语，表目的作宾语，常接在动词后作表语，说明主语是什么作状语，表原因或结果作宾补，补充说明宾语动作定语，后置修饰名词走
一感（feel）二听（listen t、hear）三让（let、make、have）四看（lk at、see、watch、ntice）宾语补语用原形，t字一定要甩掉。但变被动t回来，这个规则别忘掉。
