必修3 不定式做目的状语-备战2025-2026学年高中英语上学期期末语法全解（冀教版）

ENGLISH-必修3系列资料（冀教版） Chapter1不定式做目的状语 考频分析 不定式做目的状语是高中英语语法的重要考点，考频占语法总量的0%左右，贯穿试卷多个核心题型：单 项选择1-2题、完形填空1-2题、语法填空1题、阅读理解（辅助理解句意，明确动作目的）、书面表达 (高频使用，提升表达逻辑性与连贯性)。在语境理解类题目中，不定式与介词短语表目的的区别以及不定 式的主动表被动用法往往是解题关键。 考查内容 高中英语对不定式作目的状语的考察聚焦三大维度，覆盖基础用法与语境应用： ·基本结构识别：不定式符号to加动词原形(t和do)作目的状语的基本构成，与不定式作其他成分（如宾 语、定语)的形式区分； ·语境逻辑判断：在具体语境中通过”为了”以便”等语义线索识别不定式表目的的功能，与其他表目的结 构（如in order to、so asto)的替换与差异； ·句式转换应用：陈述句中不定式作目的状语的正常语序，与置于句首时的强调用法及标点规侧（逗号分 隔)，被动语态中不定式的正确表达。 精讲精练 知识点一：不定式作目的状语 ·基本结构(to+动词原形表目的)》 -位于句首：To improve his English,he practices speaking every day..(为了提高英语，他每天练习☐ 语) -位于句末：She studies hard to get good grades.(她努力学习是为了取得好成绩) ·逻辑关系（不定式动作是主句动作的目的） -隐含”为了.”含义：They started early to catch the first bus.(他们早早出发是为了赶上首班车) -可转换为in order to/so as to:He saved money in order to buy a new bike.(他存钱是为了买辆新自 行车) ·否定形式（在to前加not) -例句：He left quietly not to wake the baby.(他悄悄离开以免吵醒婴儿) -扩展：She decided not to go out to finish her report.(她决定不出去，为了完成报告) ·特殊用法（目的状语置于句首时的逗号分隔） 一句首目的状语需用逗号隔开：To pass the exam,we need to review carefully.(为了通过考试，我们 需要认真复习) -句末目的状语无需逗号：Ve bought some fruits to make a salad.(我们买了些水果做沙拉) 【即学即练】 1.【基本结构】 (im prove)his math,he takes extra classes every weekend.(用所给动词的不定 式形式填空) 2.【否定形式】He walked quietly wake the sleeping dog.(选择正确形式) A.to not B.not to C.don't to D.not 3.【位置用法】判断正误：To keep healthy,she eats vegetables every day..(句首目的状语加逗号，是否 正确) A.正确 B.错误 4.【逻辑关系】She works hard get a promotion.(填入合适的不定式结构) A.in order B.so as C.to D.for 5.【句式转换】将句子改为句首目的状语形式：He reads English every morning to improve his pronunci-- ation. 必修3|英语|冀教版 ENGLISH-必修3系列资料（冀教版） 知识点二：不定式做目的状语的进阶用法与易错点 ·目的状语的强调形式(in order to/so as to的区别与运用) 1.in order to的位置与用法 -可置于句首或句中，强调目的，语气强于单独的odo。 -句首例句：In order to win the competition,she trained for3 hours every day.(为了赢得比赛，她 每天训练3小时) -句中例句：We need to collect more data in order to support our argument..(我们需要收集更多数 据以支持论点) 2.so as to的位置限制 一仅可置于句中，不可位于句首。 -正确例句：He lowered his voice so as not to disturb others..(他压低声音以免打扰他人) -错误示例：So as to catch the train,they started at dawn.(应改为In order to catch the train.) ·目的状语的替代表达(for+名词代词结构) 一基本用法 *当不定式动作的逻辑宾语是名词时，可用”fo+名词”表目的，避免重复动词。 *例句对比：不定式结构：She went to the store to buy milk.(她去商店买牛奶)for结构：She went to the store for milk.(她去商店买牛奶) 一接代词的情况 *后接人称代词时，用宾格形式。 *例句：He opened the window for her to get some fresh air.(他开窗让她呼吸新鲜空气) ·逻辑主语一致性（不定式动作执行者需与主句主语一致） -正确逻辑关系 *例句：To learn painting well,Tom joined an art club.(Tom是learn的执行者，逻辑-致) 一常见错误类型 *错误示例：To improve pronunciation,.listening practice is necessary.((listening practice不能执行 improve动作，应改为To improve pronunciation,we need listening practice.) ·分隔结构与歧义规避（目的状语与结果状语的区分） 一不定式表目的与表结果的对比 *目的状语（表意图）：He stayed up late to finish the report.(他熬夜是为了完成报告) *结果状语（表意外结果）：He stayed up late,only to find the report was already done.(他熬夜却 发现报告已完成) 一逗号分隔的作用 *表结果时常用逗号分隔，且常与oly连用；表目的时句末无逗号。 *例句：She hurried to the station,only to miss the train.(结果状语，用逗号+only to) ·高老高频易错点（否定转移与固定搭配） -not的位置陷阱 *否定目的时not必须置于to前，不可置于主句动词后。 *正确例句：He pretended to be ill not to attend the meeting.(他装病是为了不去开会) *错误示例：He didn't pretend to be ill to attend the meeting.(改变了主句否定意义) -固定句式：too.to与enough to的目的用法 *too.to表”太.而不能”（隐含否定目的）：The box is too heavy to carry..(箱子太重搬不动) *enough to表”足够..去做”（肯定目的）：She is old enough to make her own decisions.(她足够 大可以自己做决定) 知识点三：不定式放目的状语的高阶应用与高考难点 ·目的状语与其它非谓语结构的区分（高考易错） 一与不定式作宾语的对比 *目的状语表动作目的，宾语表动作内容，逻辑不同。 *对比示例：目的状语：He stopped to ask the way.(他停下来是为了问路)宾语：He stopped asking questions.(他停止提问) 一与现在分词作伴随状语的区分 *伴随状语表同时发生的次要动作，目的状语表意图。 *例句对比：目的状语：She ran to catch the bus.(她跑是为了赶公交车)伴随状语：She ran crying all the way.(她一路哭着跑) ·复杂句中的目的状语（高考语法填空高频） 一主句含情态动词的目的状语 *常用"to dolin order to”,表”为了能.”。 *例句：Ve must work hard to pass the college entrance exam.(我们必须努力学习才能通过高考) -目的状语与结果状语的叠加使用 *同一语境中同时出现时，用逗号分隔结果状语。 *例句：He saved money for years to buy a house,only to find prices had risen sharply.(他存钱多 年想买房子，结果却发现房价猛涨) ·目的状语的逻辑主语特殊情况（高考改错热点） 一主句主语为物时的逻辑关系修正 *需确保不定式动作可由主语执行，否则用for sb.todo结构。 *错误示例：This book is written to explain grammar rules.(书不能主动”写”，应改为：This book is written for students to explain grammar rules. 一独立主格结构表目的 *当不定式逻辑主语与主句主语不同时使用。 *例句：The teacher spoke slowly,for students to take notes easily.(老师讲得慢，以便学生能轻松 记笔记) ·目的状语的省略现象（高考阅读理解长难句） 一上下文语境中的省略 *对话中承前省略重复的不定式内容。 *例句：A:hy did you go to the library?B:To study.(完整形式：To study for the exam.) -not to的独立使用 *单独使用表否定目的，承接上文动作。 *例句：You'd better not stay up late..If you do,not to finish homework but to rest..(你最好别熬夜。 如果熬夜，不是为了完成作业而是为了休息) ·高考写作中的目的状语高级表达（书面表达加分） -in order that引导的目的状语从句 *后接完整句子，主句常含情态动词can/could。 *例句：We set out early in order that we could arrive before dark.(我们早早出发以便能在天黑前到 达) -so that引导的目的状语从句 *需与so.that(结果状语从句)区分，so that前一般无逗号。 *目的从句：He studies hard so that he can enter a good university.(他努力学习是为了能进入好大 学) *结果从句：He studies so hard that he often forgets meals.(他学习太努力以至于经常忘记吃饭) 必修3|英语|冀教版 ENGLISH-必修3系列资料（冀教版） 考法一：不定式作目的状语的结构与否定形式
