暑假语法知识巩固专练·动词不定式作状语和宾语补足语九年级上册人教版
01 复习目标
明考向
本考点是八下语法的核心内容,在期末考中占比约15%,近3年高频考点集中在三类题型:
1. 单项选择:2-3题,重点考「感官/使役动词的to取舍」「不定式固定搭配」「too...to/enough to句型辨析」
2. 语法填空:1-2空,重点考被动语态下的to还原、不定式作目的状语的变形
3. 书面表达:正确使用不定式作目的状语可提升1-2分,是写作提分的隐形加分项
知权重
不定式是初中语法的衔接性考点:八下掌握不牢,会直接影响初三非谓语动词、复合句的学习,暑假巩固能帮学生建立语法信心,降低初三学习难度。
晓关联
不定式常与被动语态、固定动词搭配、语境逻辑结合考查,写作中若误用会导致句子结构混乱、表意不清。
定目标
1. 熟练掌握不定式作宾补的「带to/省to」规则,尤其是感官/使役动词的主动被动变化
2. 能准确区分不定式作目的、结果、原因状语的用法,熟练运用too...to等固定句型
3. 能在暑假作业、日常写作中正确运用不定式,规避高频错误
02 知识重构 脉络重构:高频考点速览
考点分类
核心考查点
易错预警
不定式作宾补
1. ask/tell/want/encourage等常规动词后接带to不定式
2. see/hear/make/let等感官/使役动词主动语态省to,被动语态必须还原to
3. find/think+宾语+to be(可省略)结构
被动语态忘加to、不定式否定形式错写为to not do
不定式作状语
1. 目的状语:to do/in order to可放句首/句尾,so as to只能放句尾
2. 结果状语:too...to(太…而不能)、adj/enough to(足够…做)、only to(意外结果)
3. 原因状语:glad/sorry/surprised+to do
so as to放句首、too...to后多余加it、only to误用于预期结果
知识点一 动词不定式作宾语补足语
核心知识梳理
宾补是对宾语的动作、状态进行补充说明,宾语和不定式构成逻辑上的主谓关系(宾语是动作的发出者),去掉宾补后句子表意不完整。
1. 接带to不定式作宾补的常规动词(to永不省略):
表要求/期望:ask, tell, want, expect, wish, encourage, advise
表允许/迫使:allow, permit, force, get
例句:Our head teacher encourages us to read more classical books.(班主任鼓励我们多读经典,us是to read的逻辑主语)
2. 接省略to不定式作宾补的特殊动词(主动省to,被动必还原):
感官动词:see, hear, watch, notice, feel
使役动词:make, let, have
例句:
主动:I saw him play basketball on the playground yesterday.(昨天我看见他在操场打篮球,省to)
被动:He was seen to play basketball on the playground yesterday.(他被看见在操场打篮球,还原to)
3. 固定结构:
find/think/consider + 宾语 + (to be) + 名词/形容词,to be可省略
例句:We find the summer camp (to be) meaningful.(我们发现夏令营很有意义)
典例破题
The heavy rain made all the students ______ their umbrellas on the way to school.
A. open B. to open C. opening D. opened
【解析】本题考查使役动词make的用法,主动语态下作宾补的不定式省略to,排除B;open和students是主动关系,排除D;句意为“大雨让所有学生在上学路上撑开了伞”,强调动作全过程用省to的不定式,选A。
【易错警示】若本题改为被动语态:All the students were made ______ their umbrellas...,则必须选B(to open),被动还原to是八下期末考最高频的丢分点。
巩固提升
1. My mom lets me ______ the dishes after dinner every day.
A. wash B. to wash C. washing D. washed
2. The teacher often reminds us ______ our homework on time.
A. hand in B. to hand in C. handing in D. handed in
3. The little boy was seen ______ kites on the playground yesterday afternoon.
A. fly B. to fly C. flying D. flew
知识点二 动词不定式作状语
不定式作状语修饰谓语动词、形容词或整句话,交代动作的目的、原因、结果,去掉后主句结构仍完整。
1. 目的状语:表“为了…”,可放句首(用逗号隔开)或句尾。强化语气可用in order to/so as to,so as to不能放句首。
例句:To improve my spoken English, I read aloud every morning.(为了提高口语,我每天早上大声朗读,不定式放句首表目的)
2. 结果状语:表动作的最终结果,三类固定句型是中考核心考点:
• only to do:表“不料/结果反倒”,强调意外、非预期的负面结果
• 形容词/副词+enough to do:表“足够…从而能做”
• too+形容词/副词+to do:表“太…而不能”,本身含否定含义,无需再加not
例句:
He hurried to the bus stop, only to find the bus had already left.(他匆忙赶到公交站,结果车已经开了,only to表意外)
The chair is strong enough to hold three kids.(椅子足够结实,能坐三个孩子)
The little kid is too short to reach the bookshelf.(孩子太矮,够不到书架)
3. 原因状语:依附带有情绪色彩的形容词,解释情绪产生的原因,常用结构:be + 情绪形容词(glad/sorry/surprised/pleased) + to do
例句:I'm glad to receive your letter.(收到你的来信我很开心)
典例破题1
______ catch the early bus, she got up at 6 o'clock this morning.
A. So as to B. In order to C. For D. To
【解析】本题考查目的状语的位置规则,so as to不能放在句首,排除A;for是介词,后接名词,排除C;句首表目的可用in order to或to,本题语境无特殊语气,选B更规范。
典例破题2
The math problem is too difficult ______ out by most students.
A. to work B. to work it C. to be worked D. working
【解析】本题考查被动语态下的too...to结构,problem是work out的逻辑宾语,无需再加it,排除B;problem和work out是被动关系,要用被动不定式to be worked,选C。
【易错警示】too...to本身含否定含义,不要错写为The problem is too difficult not to work out;work out的宾语若是不定式逻辑主语,不能重复添加代词。

Dear Tom,
I'm glad to hear that you'll come to China this summer! Here are some tips for your trip. First, you'd better book tickets online in advance to avoid crowds. Second, remember to pack light clothes, because it's hot in most cities. I will be free during your stay, so I can show you around the famous places in my city. To make your trip smoother, you can also download a translation app on your phone. I'm sure you'll have a great time here!
Yours,
Li Hua
