初中英语动词不定式用法小结
动词不定式是动词的一种非谓语形式，又叫非谓语动词，它没有人称和数的变化，在句子中不能做谓语；它由“to+动词原形”构成，这里的to是动词不定式符号，本身没有词义，其否定形式常在to前加not；由于它仍保持动词的特点，可以有自己的宾语和状语，还可以带疑问词和由for引出其逻辑主语等形成动词不定式短语；不定式或不定式短语具有名词、形容词和副词的特征，在句子中可作主语、表语、宾语、宾语补足语、定语和状语等句子成分。为使同学们更好地掌握其用法，现总结如下：
一、动词不定式作主语
动词不定式作主语时，为避免句子的头重脚轻，常用it作为形式主语，而真正的主语动词不定式后置。如要说明动作的执行者，可在不定式前加for引导的短语；但如果表语是nice, kind, clever等描述动作执行者的性格、品质的形容词时，则应在不定式前加of引导的短语。常用句型:It +be+adj./n.+(for/of sb.) to do sth./It takes sb. some time to do sth.
二、动词不定式作宾语
一些动词，如want, decide, hope, agree, learn, plan, need, teach, 等，常接动词不定式作宾语。当动词不定式作宾语时，如果后接宾语补足语，常用it作形式宾语，而把真正的宾语放在宾语补足语之后。应注意有些动词后面可接不定式作宾语，也可接动名词作宾语，但所表达的意义不同。常见的有：（1）stop to do sth.停止正在做的事，去做另一件事；stop doing sth. .停止正在做的事（2）go on to do sth. 做完一件事后，继续做另一件事；go on doing sth.继续做同一件事（3）remember/forget to do sth.记住／忘记去做某事；remember/forget doing sth. 记得／忘记做过某事
三、动词不定式作定语
动词不定式作后置定语时，与被修饰的名词逻辑上有动宾关系。如果动词不定式是不及物动词时，则要带上与之搭配的介词，构成及物动词短语。动词不定式作后置定语常用于“have/has ＋某事＋to do”或“enough＋名词＋to do”“It’s time to do sth.”等结构中。
四、动词不定式作宾语补足语
有些动词，如: tell, ask, want, invite, teach, like, call等可接带to的动词不定式作宾语补足语，构成tell/ask/want /call/invite sb. to do sth.结构。应注意动词不定式作使役动词和感官动词的宾语补足语时应省去to，在被动语态中应加上to。这些动词可归纳为“一感(feel)，二听(listen to, hear)，三让(let, make, have,，四看(look at, see, watch, notice)，半帮助(help)(即在动词help后面作宾语补足语时，to可有可无)”。另有口诀帮助记忆：“感使动词真奇怪，to在句中像妖怪，主动句中to离开，被动句中to回来。”(let不用于被动语态)
五、动词不定式作状语
动词不定式作状语主要用来修饰动词，表示目的，结果或原因。为了强调目的，有时可以把动词不定式放在句首，或在不定式前加in order或so as。常用结构有too + adj./adv. + to do sth.等。
六、固定句式中动词不定式的用法
在固定句式中对不定式的考察常见的有：had better (not) do sth./Would you like to do sth.?/Why not do sth.?/Would you please (not) do sth.?等。
