C．Yes, you must. 【答案】C 【详解】句意：——我现在必须开门吗？——是的，你必须开。 考查情态动词must的用法。在回答must开头的一般疑问句时，肯定回答用“Yes, 主语+must”，表示“是的，必须”；否定回答用“No, 主语+needn’t”或“No, 主语+don’t/doesn’t have to”，表示“不，不需要”。A选项“Yes, you need”表述错误，need不能直接用于回答must的疑问句；B选项“No, you mustn’t”中mustn’t意思是“禁止”，不符合此处语境；C选项“Yes, you must”符合must疑问句的肯定回答规则。故选C。 2．— Do we need ________ a taxi to go to the science museum? — I don’t think so. It is not far from here. Let’s ________. A．to take; ride B．take; ride C．to take; riding 【答案】A 【详解】句意：——我们去科学博物馆需要打车吗？——我不这么想。它离这儿不远。让我们骑车吧。 考查非谓语动词。根据“Do we need”可知，第一空考查need to do sth“需要做某事”，因此第一空填不定式；根据“Let’s”可知，考查let’s do sth“让我们做某事”，因此填动词原形。故选A。 3．—I’d like to keep a pet, but I’m busy studying all day. —Goldfish are a good choice. You ________ feed them every day. A．shouldn’t B．don’t need C．needn’t 【答案】C 【详解】句意：——我想养宠物，但我整天忙着学习。——金鱼是个好选择。你不需要每天喂它们。    考查情态动词辨析。shouldn’t不应该；don’t need不需要，需接to do；needn’t不需要，直接接动词原形。根据“Goldfish are a good choice”及“feed them every day”可知，金鱼的特点是无需每日投喂，空格后为动词原形“feed”，故选C。 4．—I think the classroom needs ________. —Well, you are right. We’ll do what we can ________ the classroom tidy and clean. A．clean; keep B．to clean; to keep C．cleaning; to keep 【答案】C 【详解】句意：——我认为教室需要打扫。——你说得对。我们将尽我们所能保持教室整齐和干净。 考查情态动词和非谓语动词。第一空为need doing“需要被做”，含有被动含义，相当于need to be done；第二空应用不定式作目的状语。故选C。 5．I ________ a new pair of shoes. I need to buy a new shirt instead. A．don’t need B．needn’t C．don’t need to 【答案】A 【详解】句意：我不需要一双新鞋，而我需要买一件新衬衫。 考查动词need的用法。need可作实义动词，也可作情态动词，都是“需要”的意思。第一句为“主+谓+宾”结构的句子，此处需要动词作谓语，而选项B中的need为情态动词，情态动词不能单独作谓语，因此排除选项B；选项A和C中的need均为实义动词，但选项C是“need to do sth需要做某事”这一句型的具体用法，其中to后面须接动词原形，而横线后紧接的是冠词“a”，由此排除选项C。故选A。 6．________ you need sports shoes? A．Are B．Is C．Do 【答案】C 【详解】句意：你需要运动鞋吗？ 考查一般疑问句。Are是，主语为复数；Is是，主语为单数；Do助动词，主语为复数。本题的need是行为动词，含行为动词的一般疑问句用do或does，主语是you，用do。故选C。 7．—Do we need ________ on the sidewalk? —Yes. People should ________ the traffic rules. A．to walk; obey B．to walk; to obey C．walk; to obey 【答案】A 【详解】句意：——我们需要在人行道上走吗？——是的。人们应该遵守交通规则。 考查动词不定式及情态动词的用法。need作为实义动词，后接动词不定式，即need to do sth.“需要做某事”；should是情态动词，后面接动词原形，故选A。 8．—We should not ________ late for school. —You are right. And we need ________ home on time. A．be; return to B．be; to go back C．to be; to return 【答案】B 【详解】句意：——我们上学不应该迟到。——你是对的。我们需要准时回家。 考查词义辨析和情态动词用法。return to+名词=go back to+名词，意为“回到某个地方”。空一前有should not，其后跟动词原形，可排除C选项；空二后home是副词，A选项应改为return home。故选B。 9．You ________ your work tonight. It’s time to go to bed. A．don’t need finishing B．needn’t finish C．needn’t to finish 【答案】B 【详解】句意：你不必今晚完成你的工作。该睡觉了。 考查谓语动词。need可作情态动词也可作实义动词，作情态动词时，否定式是needn’t，后跟动词原形；作实义动词时，常用于“need to do sth”的结构，主语是You，时态是一般现在时，否定式是don’t need to do sth，故选B。 10．— Do I need ________ a bus? — No, you needn’t ________ a bus, it’s near here. A．take, take B．to take, to take C．to take, take 【答案】C 【详解】句意：——我需要坐公共汽车吗？——不，你不必坐公共汽车，它就在附近。 考查need的用法。根据第一句中的do可知，need是实义动词，结构是need to do sth“需要做某事”；根据第二句中的“needn’t”可知，need是情态动词，后接动词原形，故选C。 11．—________ you ________ a sweater? —No, thanks. A．Do; need B．Are; need C．Does; sell 【答案】A 【详解】句意：——你需要一件毛衣吗？——不，谢谢。 考查一般疑问句。need是动词，需要；sell是动词，卖。根据语境可知是询问对方是否需要一件毛衣，这里need是一个实义动词，一般疑问句需要加助动词，主语是you，应用do。故选A。 12．—Must I stay here with you, Mum?   — No, you ________. You may go home now, but you ________ go to the net-bar. A．mustn’t; needn’t B．needn’t; mustn’t C．must; need 【答案】B 【详解】句意：——妈妈，我必须和你待在这里吗？——不，不需要，你可以现在回家，但是你禁止去网吧。 考查情态动词。mustn’t禁止；needn’t不需要；must一定；need需要。以must引导的一般疑问句，肯定回答用yes, you must，否定回答用no, you needn’t/no, you don’t have to，所以第一空用needn’t；根据句意可知，第二空表示“你现在可以回家，但是你禁止去网吧”，故选B。 13．We need ________ a foreign language well. A．learn B．learning C．to learn 【答案】C 【详解】句意：我们需要学好一门外语。 考查不定式。need可做情态动词和实意动词，做情态动词表示必要性，多用于疑问句、否定句或否定意义的句子，做实意动词时， 其用法为need sth/need to do sth；本句是陈述句，故选C。 14．— Need I finish my homework today? — Yes, you ________. A．need B．can C．must 【答案】C 【详解】句意：——我需要今天完成家庭作业吗？——是的，你需要。 考查情态动词的用法。need需要、必需，作情态动词时，无人称和数的变化，后接动词原形。由need引起的一般疑问句，肯定回答常用must或have to，否定回答常用needn’t。故选C。 15．— Must I finish work at once? —_____________. A．No, you can't. B．Yes, you need. C．No, you needn't. 【答案】C 【详解】句意：——我必须马上完成工作吗?——不,你不必。 考查一般疑问句及其回答。以情态动词must开头的一般疑问句，肯定回答用must，否定回答一般不用mustn’t，而用needn’t或had better not。根据句意结构，可知选C。 16．—Li Hai, ________ you speak Chinese? —Yes, but only a little. A．must B．need C．can 【答案】C 【详解】句意：—李海，你会说汉语吗？—是的，但是仅仅会一点。 考查情态动词，A. must必须；B. need需要；C. can能，会。根据回答，可知这里是在问你会说汉语吗？根据题意，故选C。 17．You_______ to the party if you're so busy. A．not need coming B．needn't come C．don't need come 【答案】B 【详解】试题分析：句意：你不必来参加聚会，如果你很忙。need需要，作为实意动词有以下几种搭配：need sth需要某物；need doing需要做，表示被动；need to do需要做，表示主动。作为情态动词，后面需跟实意动词原形，其否定式可直接在need后面加not。所以选B。 考点：考查need的用法。 18．There _________ for you to worry about her. Because she is old enough to take care of herself. A．is no need B．are no need C．are not needs 【答案】A 【详解】句意：你没有必要担心她。因为她已经足够大了可以照顾自己了。 考查need词性辨析。need作情态动词时，后接动词原形；行为动词need后接动词不定式，即need to do sth.“需要做某事”，否定形式为don’t/doesn’t/didn’t need to do sth。need作名词时，常用于固定搭配“there is no need to do sth.没有必要做某事”。根据句意可知，need在本句中是名词，根据There可知，本句是there be句型。故选A。 19．—Does he need ________ there at once? —No, he ________ leave so hurriedly because he has enough time. A．to go; doesn’t need B．go; needn’t C．to go; needn’t 【答案】C 【详解】句意：——他需要马上去那儿吗？——不，他有足够的时间，不需要这么匆忙地离开。 考查动词的用法。need既可以作实义动词也可以作情态动词。根据问句中的Does可知need在句中作实义动词，need to do sth.表示“需要做某事”，第一空用动词不定式；根据“No”和第二空后的动词原形leave可知，第2个空如果是实义动词，应填doesn’t need to ，need是情态动词时，空处用情态动词need的否定式needn’t表示“不需要”。故选C。 20．You ______ warm clothes in Shanghai, for it's quite hot this month there. A．needn't to wear B．needn't wearing C．don't need to wear 【答案】C 【详解】句意：在上海你不必穿暖和的衣服，因为在那里这个月非常热。 考查need用法。某人做主语时，need当实义动词用，后加不定式，否定要借助助动词构成；如果当情态动词时，后接动词原形，否定直接在后面加not；所以A/B选项结构错误，故选C。 二、用所给词的适当形式填空 1．They finish the work today. Tomorrow is OK. (need) 【答案】needn’t 【详解】句意：他们不必今天完成这项工作。明天也可以。根据“Tomorrow is OK.”可知，不必今天完成这项工作，可用needn’t do sth.“不必做某事”，其中needn’t是情态动词，后接动词原形。故填needn’t。 2．You need (clean) your room. It’s very dirty. 【答案】to clean/clean 【详解】句意：你需要打扫你的房间。它非常脏。need (to) do sth“需要做某事”，为固定短语。故填(to) clean。 3．They (not need) to get up early because the weekend is coming. 【答案】don’t need 【详解】句意：他们不需要早起，因为周末就要到了。根据“the weekend is coming”可知，句子时态为一般现在时，且主语“They”为第三人称复数，否定句应借助助动词don’t，后接动词原形。故填don’t need。 4．He’s all right. He (not need) any help with his Maths. 【答案】doesn’t need 【详解】句意：他没事。他的数学不需要任何帮助。need“需要”，实义动词，变为否定句需要借助助动词，时态为一般现在时，he作主语，否定助动词用doesn’t，后面加动词原形。故填doesn’t；need。 5．You don’t need (finish) it today. You can do it tomorrow. 【答案】to finish 【详解】句意：你今天不需要完成它。你可以明天做。根据“You don’t need…(finish) it today.”可知，此处为固定短语need to do sth.“需要做某事”，空处应用动词不定式形式to finish作宾语。故填to finish。 6．Thank you for (invite) us here. But I need (leave) in ten minutes. 【答案】 inviting to leave/leave 【详解】句意：谢谢你邀请我们到这里。但我需要十分钟后离开。invite邀请，动词；leave离开，动词。“thank sb for doing sth为……感谢某人”，need作实义动词时后接不定式作宾语，即“need to do sth需要干某事”，need作情态动词时后接动词原形。故填inviting；to leave/leave。 7．There is still some milk in the fridge. We buy any today. (need) 【答案】needn’t/don’t need to 【详解】句意：冰箱里还有牛奶。今天我们不需要买。根据“There is still some milk in the fridge.”可知，今天不需要买牛奶。need作情态动词时，没有人称和数的变化，其否定形式为needn’t，后加动词原形；need作实义动词时，need to do sth“需要做某事”，构成否定应借助助动词，句子应用一般现在时，主语为We，助动词用do，后加not，缩写成don’t，后加动词原形need。故填needn’t/don‘t need to。 8．—Need I __________ (go) now? —No, you needn’t. 【答案】go 【详解】句意：——需要我现在走吗？——不，你不需要。根据“needn’t”可知，问句是情态动词need开头的一般疑问句，其后跟动词原形。故填go。 9．—Do I need __________ (get) up so early tomorrow? —I don’t think so. 【答案】to get 【详解】句意：——我明天需要这么早起床吗？——我不这么认为。get up“起床”，动词短语，根据助动词“Do”可知，“need”是实义动词，其后接不定式作宾语，need to do sth.表示“需要做什么”。故填to get。 10．You need not (go) to the store to return the item. The Internet allows you to get a new one without__________ (leave) home. 【答案】 go leaving 【详解】句意：你不必到商店去退货。互联网让你足不出户就能买到一台新的。need not意为“不必”，此处need是情态动词，其后接动词原形go；介词without后接leave的动名词形式leaving作宾语。故填go；leaving。 三、完成句子 1．do, How, milk, you, need, much (连词成句) _______________________________________? 【答案】How much milk do you need? 【详解】根据所给词及标点可知，此句为疑问句，How much“多少”，询问不可数名词的数量；milk“牛奶”；do是助动词；you“你”，主语；need“需要”。故填How much milk do you need?“你需要多少牛奶？” 2．need, apples, how, do, many, we _________________________ ? 【答案】How many apples do we need 【详解】根据所给词汇和标点符号可知，本题为特殊疑问句。how many apples“多少苹果”，后跟助动词do；主语为人称代词we“我们”；谓语为动词原形need“需要”。故填How many apples do we need“我们需要多少苹果”。 3．need, don’t, you, to, rush . 【答案】You don’t need to rush. 【详解】根据所给标点可知应用陈述句的否定形式，分析所给单词，you为主语，助动词don’t放在主语之后实义动词need之前，need后跟不定式。故答案为：You don’t need to rush“你不需要着急”。 4．I need to buy some milk. (改为一般疑问句) you to buy any milk? 【答案】 Do need 【详解】句意：我需要买一些牛奶。原句时态为一般现在时，I作主语，need是实义动词；改为一般疑问句，应借助助动词do，置于主语you前，其后接动词原形need，且句首首字母要大写。故填Do；need。 5．He needs to take a break.（改为否定句） He to take a break. 【答案】 doesn’t need 【详解】句意：他不需要休息。原句中的“need”为实义动词，改为否定句时应借助助动词并在助动词后跟实义动词原形，且主语“He”为第三人称单数形式，因此助动词为does，否定形式为doesn’t。故填doesn’t；need。 6．She needs a new scarf. (改为一般疑问句) she a new scarf? 【答案】 Does need 【详解】句意：她需要一条新围巾。此句是一般现在时，主语She是第三人称单数，且句中含有实义动词needs，改为一般疑问句时需借助助动词does放在句首，句首首字母大写；does后接动词原形，所以needs要变回原形need。故填Does；need。 7．Do they need to arrive early? (作肯定回答) → Yes, . 【答案】 they do 【详解】句意：他们需要早到吗？此处是含有助动词do的一般疑问句，主语是they，肯定回答为Yes, they do。故填they；do。 8．He doesn’t need to get up so early on weekends. (改为同义句) He up so early on weekends. 【答案】 needn’t get 【详解】句意：他周末不需要那么早起床。原句中的“doesn’t need to”表示“不需要做某事”，可以用情态动词“need”的否定形式“needn’t”替换，后直接加动词原形“get”。故填needn’t；get。 9．Mary needs some help right now. (改为一般疑问句) Mary any help right now? 【答案】 Does need 【详解】句意：玛丽现在需要一些帮助。原句实义动词是needs，改为一般疑问句需借助助动词“Does”，并将其提前，后用动词原形“need”，故填Does；need。 10．He needs to buy something from the supermarket. (改为否定句) He need to buy from the supermarket. 【答案】 doesn’t anything 【详解】句意：他需要从超市买些东西。根据“needs”可知变否定句时借助助动词doesn’t；把something改为anything。故填doesn’t；anything。 题型一 补全对话 A: Mom, I don’t feel well.
