Unit 4【刷语法】疑问词+to do和must have to用法（重点语法提升练）-2024-2025学年八年级英语下册单元模块满分必刷题（牛津译林版）

2024-2025学年八年级英语下册单元模块满分必刷题（牛津译林版） Unit 4 A good read【刷语法】(重点语法提升练) 疑问词+to do和must have to 用法 1、疑问词+to do 一． “疑问词＋动词不定式”结构有两种形式： (1). “疑问词＋to＋动词原形” I don’t know what to say. 我不知道说什么。 Can you tell me how to make a paper boat？你能告诉我怎样做一只纸船吗？ (2). “疑问词＋名词＋to＋动词原形” I don’t know which topic to choose. 我不知道选哪个题目。 二． “疑问词＋动词不定式”结构在句子中作宾语、表语等 (1). 表语 The question is which to choose. 问题是选哪个。 (2). 宾语 We must know how to operate the machine. 我们必须弄懂如何操作这机器。 In one of his books, Marx gave some advice on how to learn a foreign language.在马克思的一本书中, 他对如何学习一门外语提出了一些建议。 (作介词on的宾语） 注意：“疑问词＋动词不定式”结构经常放在tell, show, teach, learn, know, wonder, discuss, remember, forget, find out等动词 (词组）之后作宾语。例如： The teacher told the students how to do the experiment. 老师教学生如何做实验。 (句中 told含有taught的意思） The young woman doesn’t know what to do. 那位年轻女子不知道怎么办。 (句中what不能改换成how） 三． “疑问词＋动词不定式”作宾语时, 相当于一个由该疑问词引导的宾语从句。例如： Excuse me. Can you tell me how to get to the bookshop?= Excuse me. Can you tell me how I can get to the bookshop? 四． 如何表达“怎么办” 在翻译“怎么办”时, 许多同学译成how to do, 实际上是犯了汉语式英语的错误, “怎么办”的实际意义是“做些什么”, 故应用代词what作动词do的宾语, 而不用副词how。只有在表达“怎样做这件事”时才说how to do it。 2、must和have to 用法区别 must 表示主语“必须”做某事，强调说话人的主观意愿; 否定形式mustn’t（禁止） have to 强调的是客观需要，意思是“不得不，得做某事”。否定形式don’t have to do sth（不必做某事） have to 有人称和数的变化: has to, had to, will have to。 必须做某事（主观意愿） must do sth. 禁止做某事 mustn’t do sth. 不得不做某事（客观需要）have to do sth. 不必做某事 don’t have to do sth. 拓展： (1) must用在一般疑问句中，肯定回答用must，否定回答用needn’t 或 don’t have to。 —Must I keep the book clean and tidy? —Yes, you must. —Must I bring my ID card（身份证）when I come here? —No, you needn’t. —No, you don’t have to. (2) must还可以表示肯定猜测，意思是“一定”。否定的猜测是can’t。 You must be hungry after all that walking. 走了那么远的路，你一定饿了吧。 That can’t be Lucy. She has gone to America. 那肯定不是露西，她已经去了美国。 过关测试满分：75分，时间：50分钟 一、单项选择（每小题1分，共60分） 1．（23-24八年级下·西藏拉萨·期末）The math problem is so difficult, and I really don’t know ________.

Can you tell me how to get to the bookshop?= Excuse me. Can you tell me how I can get to the bookshop? 四． 如何表达“怎么办” 在翻译“怎么办”时, 许多同学译成how to do, 实际上是犯了汉语式英语的错误, “怎么办”的实际意义是“做些什么”, 故应用代词what作动词do的宾语, 而不用副词how。只有在表达“怎样做这件事”时才说how to do it。 2、must和have to 用法区别 must 表示主语“必须”做某事，强调说话人的主观意愿; 否定形式mustn’t（禁止） have to 强调的是客观需要，意思是“不得不，得做某事”。否定形式don’t have to do sth（不必做某事） have to 有人称和数的变化: has to, had to, will have to。 必须做某事（主观意愿） must do sth. 禁止做某事 mustn’t do sth. 不得不做某事（客观需要）have to do sth. 不必做某事 don’t have to do sth. 拓展： (1) must用在一般疑问句中，肯定回答用must，否定回答用needn’t 或 don’t have to。 —Must I keep the book clean and tidy? —Yes, you must. —Must I bring my ID card（身份证）when I come here? —No, you needn’t. —No, you don’t have to. (2) must还可以表示肯定猜测，意思是“一定”。否定的猜测是can’t。 You must be hungry after all that walking. 走了那么远的路，你一定饿了吧。 That can’t be Lucy. She has gone to America. 那肯定不是露西，她已经去了美国。 过关测试满分：75分，时间：50分钟 一、单项选择（每小题1分，共60分） 1．（23-24八年级下·西藏拉萨·期末）The math problem is so difficult, and I really don’t know ________. A．how to do it B．how to do C．what to do it D．which to do 【答案】A 【详解】句意：这道数学题太难了，我真不知道怎么做。 考查宾语从句的简化。do为及物动词，后应接宾语。how不能充当宾语，故排除B项；C项中，do已有宾语it，故不能用what，应排除；结合“The math problem is so difficult,”可知，应该说这道题太难，不知道如何做。故选A。 2．（23-24八年级下·江苏宿迁·期末）One of these small men began talking to me, but I didn’t know __________. A．when to say B．what to say C．how to say D．what to say it 【答案】B 【详解】句意：其中一个矮个子男人开始跟我说话，但我不知道说什么。 考查疑问词加不定式的用法。when to say何时说；what to say说什么；how to say如何说；what to say it错误表达。根据“One of these small men began talking to me, but I didn’t know...”可知，空处指我不知道“说什么”，需what to say，在句中作宾语。故选B。 3．（23-24八年级下·甘肃定西·期中）I have got a new laptop, but I don’t know ________ it. A．what to use B．which one to use C．why to use D．how to use 【答案】D 【详解】句意：我刚刚买了一个新笔记本电脑，但我不知道如何使用它。 考查疑问词+to do用法。what to use用什么；which one to use用哪一个；why to use为什么用；how to use如何用。根据“but I don’t know...it”可知，空处指“如何用”，how to use it是“特殊疑问词＋动词不定式”的复合结构，作动词know的宾语。故选D。 4．（23-24八年级下·江苏宿迁·期中）There are different kinds of books in Xinhua bookstore. I don’t know ________. A．what to buy B．which to buy C．how to buy D．where to buy 【答案】B 【详解】句意：新华书店里许多不同种类的书，我不知道买哪一本。 考查宾语从句的用法。know后跟一个宾语从句，当从句中省略主语和助动词时，可用特殊疑问词+to do来代替。根据“There are different kinds of books in Xinhua bookstore.”可知，因书的种类多，所以不知道买哪一本，故用which to buy。故选B。 5．（23-24八年级下·全国·课后作业）He didn’t know English at all, so he can’t understand ______ the machine. A．what to control B．to control what C．how to control D．to control how 【答案】C 【详解】句意：他根本不懂英语，所以他不知道如何控制这台机器。 考查宾语从句的简化。根据“he can’t understand”可知，该句是宾语从句，当从句的主语与主句主语一致时，宾语从句可简化为不定式结构，结合“the machine.”可知，应该是如何操控机器。故选C。 6．（21-22八年级下·全国·单元测试）—Tom, can you tell me ________ an e-mail to you? —Of course. It’s easy. A．how can I send B．how I could send C．how to send D．what to send 【答案】C 【详解】句意：——汤姆，你能告诉我怎样给你发送一份电子邮件吗? ——当然了，很简单。 考查宾语从句的简化。题干中，tell me后需要接宾语补足语，宾语从句的语序需用陈述语序，选项A不对，可排除；主句时态是一般现在时，从句时态无需用过去时，选项B可排除；根据“ It’s easy.”可知很容易，因此是询问怎样发邮件，应用how引导的宾语从句，可简化为“疑问词+动词不定式”的结构。故选C。 7．（22-23八年级下·全国·单元测试）I wasn’t sure what ________ for my school project, so I asked my dad what I should do. A．write B．writing C．wrote D．to write 【答案】D 【详解】句意：我不确定我的学校作业该写些什么，所以我问我爸爸我该写什么。 考查非谓语动词。根据“I wasn’t sure”可知，what引导宾语从句，此时可用“疑问词+动词不定式”的结构，故此处应用动词不定式to write。故选D。 8．（24-25八年级上·安徽安庆·期末）The math problem is so difficult that no one knows ________ it. A．what to solve B．how to solve C．when to solve D．why to solve 【答案】B 【详解】句意：这道数学问题太难了，以至于没人知道怎么解决它。 考查疑问词+动词不定式结构。what to solve解决什么；how to solve如何解决；when to solve什么时候解决；why to solve为什么解决。根据“The math problem is so difficult that no one knows...it.”可知，没有人知道如何解这道数学题。故选B。 9．（24-25八年级上·湖南永州·期末）I can’t work out the problem. Can you tell me ________? A．how to do B．what to do it C．how to do it D．what should to do 【答案】C 【详解】句意：我解决不了这个问题。你能告诉我怎么做吗？ 考查疑问词+动词不定式。do是及物动词，需要宾语，因此排除A；选项D结构不完整，排除；选项B中what已经是do的宾语，不能再加it，排除B。选项C完整且正确。故选C。 10．（24-25八年级上·四川自贡·阶段练习）Could you tell us how ________ vegetable soup? A．makes B．to make C．making 【答案】B 【详解】句意：你能告诉我如何做蔬菜汤吗？ 考查非谓语动词。根据“Could you tell us how…vegetable soup?”可知，此处指“如何做蔬菜汤”，how to do sth.“如何做某事”，固定搭配。故选B。 11．（24-25七年级上·全国·单元测试）—Millie, I don’t know________. Can you give me some advice? —Why not ________ this red shirt and that pair of jeans? A．what to wear; to wear B．what to wear; wear C．how to wear; to wear D．how to wear; wear 【答案】B 【详解】句意：——米莉，我不知道穿什么。你能给我一些建议吗？——为什么不穿这件红色的衬衫和那条牛仔裤呢？ 考查疑问词+不定式和固定搭配。what to wear穿什么；how to wear怎么穿。第一空根据“Why not…this red shirt and that pair of jeans?”可知，此处是询问穿什么衣服，应用what to wear；第二空why not do sth“为什么不做某事？”，应用动词原形wear。故选B。 12．（23-24八年级上·四川自贡·阶段练习）Would you mind _________ me how ________ English words? A．telling;  remember B．tell；remember C．to tell; to remember D．telling; to remember 【答案】D 【详解】句意：你介意告诉我如何记住英语单词吗？ 考查非谓语动词。由“Would you mind”可知，mind doing sth.“介意做某事”，空一需使用动名词形式telling；由“how”可知，how后接to do不定式表示方式或目的。故选D。 13．（2025八年级下·全国·专题练习）—What time will you go to Beijing by plane tomorrow? —I haven’t got the ticket, so I don’t know ________to leave. A．what B．how C．where D．when 【答案】D 【详解】句意：——明天你将几点乘飞机去北京？——我还没买飞机票，所以我不知道什么时候离开。 考查特殊疑问词辨析。what什么；how怎样；where在哪里；when什么时候。根据“What time will you go to Beijing by plane tomorrow?”及“I haven’t got the ticket”可知，此处应是说不知道离开的时间。故选D。 14．（24-25八年级上·全国·假期作业）—Do you like playing the piano? —Yes, but I don’t know __________ play it well． A．what B．how C．what to D．how to 【答案】D 【详解】句意：——你喜欢弹钢琴吗？——是的，但我不知道怎样才能弹好它。 考查特殊疑问词。what什么；how怎么样；what to什么，且后加动词原形；how to怎么样，且后加动词原形。根据“I don’t know ... play it well”可知，我不知道如何弹好钢琴。play是动词原形，故用how to，构成“特殊疑问词+不定式”结构。故选D。 15．（24-25八年级上·江苏南通·期中）—Can you tell me ________ to join the DIY Club? —Scan the QR code (扫二维码) and then fill in the form of personal information on your phone. A．when B．what C．why D．how 【答案】D 【详解】句意：——你能告诉我怎样加入DIY俱乐部吗？  ——扫描二维码，在手机上填写个人信息表格。 考查特殊疑问词。when什么时候；what什么；why为什么；how怎样。结合答句“Scan the QR code and then…扫描二维码然后……”可知，问句应在询问对方该怎么作，是对“方式”提问，应用how表示“怎么样，如何”。故选D。 16．（23-24八年级下·江苏徐州·期中）—May Day holiday is coming. Which city are you going to visit? —Oh, I haven’t decided ________.
