（学好英语很重要。）常用结构(形式主语It)公式：It+谓语动词+todosth.例句展示：ItisimportanttolearnEnglishwell.

（it作形式主语，真正主语后置）动词不定式作宾语核心结构公式动词+todosth.例如：wanttodo,hopetodo,decidetodo常接不定式的动词want,hope,decide,plan,offerlearn,promise,refuse,expect,wish典型例句解析1.Shehopestotravelaroundtheworld.解析：她希望环游世界。hopes后接totravel作宾语。2.Theydecidedtostartanewproject.解析：他们决定启动一个新项目。decided后接tostart作宾语。3.Herefusedtohelpus.解析：他拒绝帮助我们。refused后接tohelp作宾语。动词不定式作宾语补足语核心结构公式动词+sb.+todosth.

常见动词：ask,tell,want,teach,encourage...经典例句解析Myteacheraskedmetostudyhard.

解析：tostudyhard补充说明宾语me的动作特殊情况：省略to的情况适用动词：使役动词：let,make,have感官动词：see,watch,hear,feel...例句对比：Isawhimplaybasketball.（正确：省略to）vs（错误：toplay）动词不定式作状语核心功能：作目的状语含义：表示动作发生的目的，常译为“为了……”结构：todosth.典型例句解析Icameheretoseeyou.(我来这儿是为了看你)ToimprovemyEnglish,Ijoinedaclub.(句首目的状语)其他功能拓展虽然不定式最常用作目的状语，但它也可以在句中充当其他成分：结果状语：常与only连用，表示意料之外的结果原因状语：表示情绪产生的原因写作高分技巧在书面表达中，灵活使用不定式可以让句式更丰富：当不定式短语置于句首时，需用逗号与主句隔开可以用inorderto或soasto来强调目的，语气更强烈动词不定式作定语核心规则与结构位置特征：不定式短语必须放在被修饰的名词或代词之后。

逻辑关系：不定式与被修饰词之间通常存在逻辑上的动宾关系。经典例句解析Ihavealotofhomeworktodo.解析：todo修饰homework(我有很多要做的作业)Sheisalwaysthefirsttoarrive.解析：toarrive修饰thefirst(她总是第一个到达的人)动词不定式与疑问词连用核心结构公式基本形式：

疑问词+todo

常见疑问词：What(什么)How(如何)Where(哪里)When(何时)句法功能该结构相当于名词性从句，可在句中充当多种成分：

作主语(Subject)作宾语(Object)作表语(Predicative)

注：常接这类结构的动词有know,decide,learn等。典型例句解析1.作主语Howtosolvethisproblemisveryimportant.（如何解决这个问题非常重要）
