A. In order to B. So that C. Because of D. Thanks to 答案：A 解析：问句询问早起的原因，答句需体现目的 “为了赶上首班车”。A 选项 “In order to” 后接动词原形，可作目的状语，符合题意；B 选项 “So that” 引导目的状语从句，后需接完整句子，此处 “catch” 是动词原形，不符合；C 选项 “Because of” 和 D 选项 “Thanks to” 后接名词或名词短语，表 “因为”“多亏”，与目的无关，故选 A。 2.We should plant more trees ______ our city more beautiful. A. make B. to make C. making D. made 答案：B 解析：句子表达 “种树” 的目的是 “让城市更美丽”，需用动词不定式作目的状语。A 选项 “make” 是动词原形，不能直接作状语；C 选项 “making” 是现在分词，常表伴随或主动；D 选项 “made” 是过去分词，常表被动或完成，均不符合目的状语的用法，故选 B。 3.______ improve his spoken English, Tom practices speaking English every day. A. So as to B. In order to C. So that D. Because 答案：B 解析：句首需要一个能接动词原形、表目的的结构。A 选项 “So as to” 不能用于句首；C 选项 “So that” 引导从句，后接完整句子，此处 “improve” 是动词原形，不符合；D 选项 “Because” 表原因，与题意不符；B 选项 “In order to” 可用于句首，后接动词原形作目的状语，故选 B。 考点 2：动词不定式作宾语补足语（带 to） 部分动词（如 want, ask, tell, wish, encourage 等）后接宾语时，需用 “动词 + 宾语 + to do” 的结构，此时不定式作宾语补足语，“to” 不能省略。中考常考查此类动词与不定式的搭配。 巩｜固｜练｜习 1.Our teacher often encourages us ______ more books in our free time. A. read B. reading C. to read D. readed 答案：C 解析：“encourage” 是常见的接带 to 的不定式作宾语补足语的动词，其固定搭配为 “encourage sb. to do sth.”（鼓励某人做某事）。A 选项 “read” 是动词原形，不符合搭配；B 选项 “reading” 是动名词，也不符合；D 选项 “readed” 表述错误，read 的过去式和过去分词均为 “read”，故选 C。 2.My parents always tell me ______ too much time playing computer games. A. not to spend B. don't spend C. not spend D. to not spend 答案：A 解析：“tell” 的固定搭配为 “tell sb. to do sth.”，其否定形式为 “tell sb. not to do sth.”（告诉某人不要做某事）。B 选项 “don't spend” 是祈使句的否定形式，不能用于 “tell sb.” 后；C 选项 “not spend” 缺少 “to”，不符合搭配；D 选项 “to not spend” 否定词位置错误，应将 “not” 放在 “to” 前，故选 A。 3.The manager asked his secretary ______ the report before five o'clock this afternoon. A. finish B. finishes C. to finish D. finishing 答案：C 解析：“ask” 是接带 to 的不定式作宾语补足语的动词，固定用法为 “ask sb. to do sth.”（要求某人做某事）。A 选项 “finish” 是动词原形，不符合；B 选项 “finishes” 是第三人称单数形式，用于主语是第三人称单数的句子中作谓语，此处不是谓语成分；D 选项 “finishing” 是动名词，不符合 “ask” 的搭配，故选 C。 考点 3：动词不定式作宾语补足语（不带 to） 使役动词（如 make, let, have）和感官动词（如 see, watch, hear, notice, feel）后接宾语时，不定式作宾语补足语，“to” 需省略，即 “动词 + 宾语 + do” 的结构。但当这些动词用于被动语态时，“to” 要还原。这是中考中易混淆的考点。 巩｜固｜练｜习 1.We saw Tom ______ basketball with his friends on the playground yesterday afternoon. A. play B. to play C. playing D. played 答案：A 解析：“see” 是感官动词，此处表示 “看到汤姆打篮球” 的全过程，其主动语态下接不定式作宾语补足语时 “to” 省略，结构为 “see sb. do sth.”。B 选项 “to play” 多在 “see” 用于被动语态时出现；C 选项 “playing” 表示 “看到正在做某事”，与 “yesterday afternoon”（强调全过程）不符；D 选项 “played” 是过去式，不能作宾语补足语，故选 A。 2.My mother often lets me ______ the dishes after dinner. A. wash B. to wash C. washing D. washed 答案：A 解析：“let” 是使役动词，主动语态下接不定式作宾语补足语时 “to” 省略，固定搭配为 “let sb. do sth.”（让某人做某事）。B 选项 “to wash” 不符合 “let” 的搭配；C 选项 “washing” 是动名词，不能作宾语补足语；D 选项 “washed” 是过去分词，表被动，此处 “我” 是 “洗盘子” 的主动执行者，不符合，故选 A。 3.The little boy was made ______ his homework again because he made many mistakes. A. do B. to do C. doing D. done 答案：B 解析：“make” 是使役动词，主动语态下接 “make sb. do sth.”，但用于被动语态时，“to” 要还原，即 “sb. be made to do sth.”。A 选项 “do” 缺少 “to”，不符合被动语态用法；C 选项 “doing” 和 D 选项 “done” 均不符合 “make” 被动语态的搭配，故选 B。 ◇Part 03 语法强化训练 提｜升｜练｜习 一、单项选择 1．________ the final exam, Jack refused ________ with his friends last weekend.

out出去。第一个空表示目的，根据句意“为了通过期末考试”，应用不定式作目的状语，“To pass”符合语境；第二个空refused后接不定式to go out，表示拒绝做某事，是固定搭配。故选C。 2．B 【解析】句意：在11.11购物节之前，网店尽一切可能来吸引顾客的注意力。 考查非谓语动词。根据句意可知，网店尽一切可能的目的就是为了吸引顾客的注意力，动词不定式表目的。故选B。 3．C 【解析】句意：科学家们正在努力工作，以帮助熊猫生育更多的幼崽并过上更好的生活。 考查非谓语动词。根据“Scientists are working hard…pandas have more babies”可知，此处表示目的，用动词不定式作目的状语。故选C。 4．D 【解析】句意：我们应该尽最大努力学好英语，因为它非常重要。 考查非谓语动词。try one’s best to do sth.是固定搭配，意为“尽某人最大努力做某事”，因此空格处应填入to learn。故选D。 5．C 【解析】句意：科学家们正在努力工作，以便帮助熊猫有更多的宝宝并在野外安全生活。 考查动词不定式作目的状语。work hard后常接不定式to do表示目的，选项C为to help，符合语法要求。故选C。 6．C 【解析】句意：政府已经采取行动在江苏为野生动物建立更多的自然保护区。 考查动词不定式作目的状语。create创建，动词原形；creating创建，动名词；to create创建，动词不定式；created创建，动词过去分词。take action to do sth.是固定搭配，意为“采取行动做某事”，故此处需用动词不定式作目的状语。故选C。 7．A 【解析】句意：——Daniel，你能和我分享你的学习方法吗？——为了学习好 (知识)，你首先需要强烈的动力和好习惯。 考查非谓语动词。根据“... well, you need to have strong drive and good habits first.”可知，“有强烈的动力和良好的习惯”的目的是“学习好”，此处要用动词不定式“To learn”作目的状语。故选A。 8．C 【解析】句意：富兰克林经常借书并读到深夜，以便早早归还它们。 考查不定式表示目的的用法。根据“Franklin often borrowed books and read late into the night ... them back early.”可知，读到深夜的目的是早早归还，此处需用不定式to return连接前后动作，表示目的。故选C。 9．C 【解析】句意：露西每天早起是为了有足够的时间为她的小妹妹做早餐。 考查不定式作目的状语。根据“Lucy gets up early every morning…enough time to make breakfast for her little sister.”的语境可知，每天早起的目的是有足够的时间为她的小妹妹做早餐，应用不定式作目的状语。故选C。 10．A 【解析】句意：生活在寒冷地区的人们更喜欢在家里使用暖色，以营造一种温暖而美好的感觉。 考查非谓语动词。根据“People living in cold areas prefer warm colors in their homes...a warm and nice feeling.”可知，此处表示目的，使用动词不定式作目的状语，即生活在寒冷地区的人们在家使用暖色的目的是营造一种温暖而美好的感觉。故选A。 11．D 【解析】句意：我在新学校遇到了一个新朋友。我们很高兴见到彼此。 考查非谓语动词。be happy to do sth.“高兴做某事”，固定搭配，因此这里应用动词不定式to meet。故选D。 12．A 【解析】句意：Lily很善良，她总是乐意帮助我们。 考查动词不定式的用法。be ready to do sth.表示“乐意做某事”，此处指乐意帮助我们。故选A。 13．A 【解析】句意：我们的同学们随时准备帮助别人。 考查短语辨析。be ready to do sth.准备做某事；be ready for sth.为某事做好准备，后面接名词。空格处后面是动词help，所以用be ready to，主语classmates是复数，be动词用are，故选A。 14．D 【解析】句意：我们准备好参加考试了。 考查动词短语。根据“We are ready”可知，考查be ready to do sth“准备好做某事”，为固定短语。故选D。 15．B 【解析】句意：这个小女孩害怕待在黑暗中。 考查非谓语动词。be afraid to do sth.表示“因害怕而不敢做某事”。故选B。 16．A 【解析】句意：期中考试即将来临，因此学生们忙于复习功课，没时间玩游戏。 考查动名词作宾语和动词不定式作结果状语。going over复习，动名词；to go over复习，动词不定式；going through浏览，动名词；to go through浏览，动词不定式。be busy doing sth“忙于做某事”，排除B、D；根据“The mid-term exam is coming”可知，期中考试要到了，所以此处是指忙于复习功课，用go over表示“复习”，too+adj/adv+to do sth“太……以至于不能做某事”，动词不定式作结果状语。故选A。 17．D 【解析】句意：——老师讲得太快了，我跟不上。——我们让她讲得更慢些。 考查副词短语。enough…to足够……做某事；such…that如此……以至于，such后接名词；so…that如此……以至于，so后接形容词或副词；too…to太……而不能。根据答语“Let’s ask her to speak more slowly.”可知，此处指老师讲得太快，我“跟不上”，用too...to...结构。故选D。 18．B 【解析】句意：男孩们太累了，无法继续行走。 考查固定短语辨析。so...that如此……以至于，that后接从句；too...to太……而不能，to后接动词原形；enough...to足够……可以，但enough通常放在形容词之后；much...to不是固定搭配，用法不恰当。根据“...tired ...walk on”可知，此处表示“太累而不能继续行走”，第二空后是动词原形，因此使用too...to结构。故选B。 19．B 【解析】句意：杰克今天忙于做数学题，不能和你一起去。 考查非谓语及too...to...的结构。根据“Jack is too busy”可知，第一空是be busy doing sth的结构，因此空格处应该为动词ing形式，所以排除C项和D项；根据“too busy...with you”可知，第二空是too...to...的结构，表示“太……而不能……” ，因此空格处应该为to do的结构，所以排除A项。故选B。 20．B 【解析】句意：这些东西通常太小而看不见。 考查非谓语。根据“These things are usually too small...”可知，此处是too...to...“太……以至于不能……”，是固定搭配，空处应是to see。故选B。 21．C 【解析】句意：有时我发现物理问题对我来说太难了而解不出来。 考查动词短语。work out解决。根据“Sometimes I find physics problem are too hard for me to”可知，此处是指解不出物理题，句子已出现“physics problems”，同一句话无需再次使用代词指代，排除A/B选项；且此处逻辑主语是me，因此用不定式的主动形式。故选C。 22．A 【解析】句意：这个问题很难回答。 考查“主语 + be + adj. + to do”结构。在“主语 + be + adj. + to do”结构中，如果形容词描述事物的特征，且句子的主语是不定式动作的承受者时不定式用主动形式表示被动意义，分析题目可知形容词“difficult”描述“question”的特征，而“question”为“answer”的承受者，故选A。 23．A 【解析】句意：没有什么能让他改变主意。 考查非谓语动词。make sb. do sth.为固定搭配，意为“让某人做某事”，其中make为使役动词，后面接不带to的动词原形作宾语补足语，所以此处应用change。故选A。 24．B 【解析】句意：大多数父母期望他们的孩子在考试中取得好成绩。 考查动词不定式。expect sb. to do sth.“期望某人做某事”。故选B。 25．A 【解析】句意：好消息！约翰在100米短跑中赢得了金牌。我看着他完成了比赛。 考查非谓语动词。watch sb do sth“看见某人做某事”，表示看到动作的全过程，此处用不带to的动词不定式。故选A。 26．C 【解析】句意：我们的班主任总是鼓励我们加入学校的各类团队。 考查非谓语动词。join动词原形；joining动名词/现在分词；to join动词不定式；joined动词过去式/过去分词。根据“encourages us…”可知，这里是encourage sb. to do sth.表示“鼓励某人做某事”，此处需要用动词不定式，to join符合语境。故选C。 27．B 【解析】句意：我的父母建议我在寒假期间做一份兼职工作来获得经验。 考查非谓语动词。take动词原形；to take动词不定式；taking动名词；took过去式。动词advise的用法，其结构为“advise sb. to do sth.”，意为“建议某人做某事”。故选B。 28．C 【解析】句意：我的父母建议我加入环境保护俱乐部，以了解更多关于自然的知识。 考查非谓语动词。根据“advised me”可知，advise sb to do sth“建议某人做某事”，是固定搭配，其中动词不定式to do作宾语补足语。故选C。 29．D 【解析】句意：在会议期间，你可以自由地分享你的观点。 考查动词不定式的用法。根据“During the meeting, you can feel free…your opinions.”可知，“feel free”后常接动词to do不定式，表示“随意做某事”。故选D。 30．C 【解析】句意：医生指导我们要多留意，把生病的猪和我们隔离。 考查非谓语动词。根据“The doctor led us...more attention to...the sick pigs away from us.”可知，led是动词lead的过去式，lead sb. to do sth.是常用搭配，意为“指导某人做某事”，不定式作宾语补足语，故空一用to pay；pay attention to中的to是介词，后接动名词形式，故空二用keeping。故选C。 二、 31． deal with 【解析】对照中英文可知，缺少“处理”，用动词短语deal with。advise sb to do sth“建议某人做某事”，空处动词用原形。故填deal；with。 32． makes laugh 【解析】使某人做某事：make sb. do sth.；发笑：laugh；根据“often”可知句子是一般现在时，主语是he，谓语动词用单三。故填makes；laugh。 33． asked me to clean 【解析】根据句意可知，此处表示“让某人做某事”，用结构“ask sb. to do sth.”，且由“last weekend”可知句子时态是一般过去时，“ask”的过去式是“asked”，“我”在句中作“ask”的宾语，用宾格“me”，“打扫”是“clean”，故填asked；me；to；clean。 34． make his bed 【解析】根据句意可知，此处表示“整理床铺”，用动词短语“make one’s bed”，句子中是“汤姆整理他的床铺”，汤姆是男性，所以用“his”表示“他的”，又因为“ask sb. to do sth.”是固定用法，表示“要求某人做某事”，所以这里用动词原形“make”。故填make；his；bed。 35． not to worry about 【解析】根据句意可知，此处表示“不要担心”，固定短语为“tell sb. not to do sth.”，意为“告诉某人不要做某事”，“担心”用短语“worry about”表示。故填not；to；worry；about。 36． uses to learn 【解析】根据中英文对照可知，此处缺少“使用”和“学习”，“使用”英文表达为use；“学习”英文表达为learn。句子主语Mike是第三人称单数，时态为一般现在时，故use需变形为uses；“用某物做某事”用固定短语use sth. to do sth.，因此“学习”前需加to，后接动词原形learn。故填uses；to；learn。 37． take action to 【解析】根据中英文对照可知，此处缺少“采取行动”，take action to do sth“采取行动做某事”，情态动词should后接动词原形。故填take；action；to。 38． makes sure avoid making 【解析】根据中英文对照，空格处缺少“确保……以避免……”。句型结构为“主语+make(s) sure+that从句+to avoid doing sth. ”，其中make sure表示“确保”，主语He是第三人称单数，且always表明是一般现在时，因此为makes sure； avoid doing sth.表示“避免做某事”，“犯错误”是make mistakes，avoid后接动名词making作宾语。故填makes；sure；avoid；making。 39． warm up 【解析】对照中英文可知，缺少“暖暖身子”，用动词短语warm up。此句用动词不定式表示喝茶的目的，空处动词用原形。故填warm；up。 40． take steps/action/measures to to meet 【解析】根据中英文对照可知，前半句缺少“采取措施……”，空格前“will”是助动词，故谓语动词应用原形，故应用take steps/action/measures to连接；后半句缺少“以迎合……”，表目的，作目的状语，应用动词不定式，故应用to meet连接。故填take；steps/action/measures；to；to；meet。 41． glad/happy to meet/see 【解析】根据中英文提示可知，空格处表示“很高兴见到”；“be glad/happy to do sth.”是一个常用的表达结构，意思是“很高兴做某事”，“meet/see”表示“见到”。故填glad/happy；to；meet/see。 42． is ready to 【解析】根据所给汉语意思可知，空缺处应该填的是“非常愿意”，用短语be ready to“乐意做某事”，时态是一般现在时，主语是Amy，be动词用is，故填is；ready；to。 43． felt excited to see 【解析】根据中英文对照可知，feel excited to see表示“感到很兴奋看到……”，句子描述的是过去在音乐会上的经历，时态为一般过去时，所以应用feel的过去式felt。故填felt；excited；to；see。 44． glad to see 【解析】根据中英文对照可知，be glad to do sth“很高兴做某事”，固定搭配；see“看”，动词。故填glad；to；see。 45． to meet 【解析】根据句意可知，此处表达“很高兴见到你”，常用英文表达是“Nice to meet you”，其中“to meet”是动词不定式作原因状语，表示“见到你很高兴”的原因。故填to；meet。 46． to be 【解析】根据中英文对照可知，此处缺少“成为”，其英文表达为be；be happy to do sth.“很高兴做某事”，固定搭配。故填to；be。 47． concentrate/focus on 【解析】对比中英文可知，空格处缺少“集中精力在……上”，其英文表达为concentrate on或focus on，均为“动词+介词”结构，后常接名词 (短语)、代词或动名词作宾语；空格前有动词不定式符号to，这里应用动词原形concentrate/focus。故填concentrate/focus；on。 48． When to find 【解析】根据中英文对照可知，第一空缺少 “当……时候”，引导时间状语从句且位于句首，首字母需大写，对应的英文表达为When；find“发现”，分析句子可知，此处是动词不定式作状语。故填When；to；find。 49． races to watch 【解析】根据中英文对照可知，第一空缺少“比赛”，race，可数名词，根据后面的be动词“were”可知，此处要用复数；第二、三空缺少“看”，watch，动词。又根据短语be interesting to do“做……是有趣的”，可知，此处动词要用不定式。故填races；to；watch。 50． to deal with 【解析】由中英文可知本句用“主语+be+形容词+to do”的结构，所以第一空填动词不定式符号to，后两空用短语“应付deal with”。故填to；deal；with。 ( 1 / 1 )学科网（北京）股份有限公司 学科网（北京）股份有限公司 $

动词原形）作状语时，主要用来表示目的、结果或原因，在句子中起补充说明的作用。 表示目的：相当于 “为了……”，常位于句首或句末，句首时可加逗号与主句隔开。例如：She gets up early to catch the early bus.（她早起是为了赶上早班车。） 表示结果：常与 only 连用，意为 “不料……；结果却……”，表示出乎意料的结果。例如：He rushed to the station only to find the train had left.（他冲到车站，不料却发现火车已经开走了。） 表示原因：常用来解释主语做某事的原因，多位于形容词后。例如：I'm glad to see you.（见到你我很高兴。） 巩｜固｜练｜习 1. 单项选择题 ① She studies hard ______ get good grades in the exam.

Because 考点 2：动词不定式作宾语补足语（带 to） 部分动词（如 want, ask, tell, wish, encourage 等）后接宾语时，需用 “动词 + 宾语 + to do” 的结构，此时不定式作宾语补足语，“to” 不能省略。中考常考查此类动词与不定式的搭配。 巩｜固｜练｜习 1.Our teacher often encourages us ______ more books in our free time.
