单项填空
1．D。本题考查情态动词的用法。根据句意“我们希望明天有尽可能多的人能够参加我们的野餐”。可知应选D项。
2．A。考查情态动词的用法。shall用于第一、第三人称，表示征求意见。would一般用于第二人称。can表示许可，一般用于否定句和疑问句。might表示委婉语气。
3．B。本题考查考生对情态动词表示推测含义的掌握和运用能力。句意为“我们也许不能成
为伟大的探险者，但我们在过去的十年里完成了从未有过的最伟大的远征”。根据句意可知，这里应该填情态动词表示推测。对过去情况的推测应使用情态动词的完成式；表示不十分有把握的否定推测不能使用mustn’t．而needn’t和shouldn’t加动词的完成式一般不用于表示推测。所以B项may not“可能不”是正确答案。
4．C。should have done意为“本应做某事但没做”；could have done意为“可能做了某事”；needn’t have done意为“没有必要做某事但却做了”。根据句意可知C项最佳。must表推测时不能用在否定句中。
5．C。本题考查情态动词的用法。A项指“禁止”；B项有“命令，允诺”等意思；C项表示主观的不应该或按客观推测不应该；D项意为“不必”。
6．B。本题考查情态动词的用法。shouldn’t have done表示“不应该做而做了”。couldn’t have done表示对过去事情的否定推测。句意为“事故发生时我不可能已经六岁多了”。
7．C。考查情态动词的用法。句子的意思为“想要找一本书，你不一定要知道作者的名字，你通过书名也能找到”。由题意可知应选C项。
8．C。考查情态动词的用法。由题干中的for可知，此处要用表示推断的情态动词。注意：must arrive用来对现在或将来的情况进行推断；can have arrived只用于疑问句或否定句中；must have arrived用来推断过去的情况；has arrived是一种客观陈述。
9．B。考查情态动词的用法。must必须；一定。句意为“我们全家人都盼望见到你。这个周末，你一定要来和我们一起吃晚饭”。如：I must shut the door，or the rain will e in．我必须把门关上，不然雨就进来了。
10．A。考查情态动词的用法。答句句意为“由于某种原因，我是坐火车回来的。尽管我本可以坐飞机回来”。这是对过去情况的叙述，所以只能在A、D两项中选。could have done 表示“过去本可以做某事却没有做”；would have done表示“过去将要做某事却没有做”。结合句意可知A项正确。
11. B。句意：“存包处”是行李可以短期存放的地方，特别是在火车站。根据句意，选B。can表示客观存在的可能性。
12.C。句意：你一定不要在这家博物馆里照相，那是禁止的。表示“禁止，一定不要”用mustn’t。
13. B。句意：开会时间快到了，经理应该马上到。表示“按道理”的推测，用should。
14. C。句意：没有图书管理员的许可不得把书拿出图书馆。要表示一种规则、命令，要用shall。
15. D。句意：从他脸上担心的表情判断，我们知道他一定是有了麻烦。must have done表示对过去事情的很肯定的推测。
16. B。从上句可知“汤姆已经工作了9个小时了”，第二个人推测“他一定很累了”，所以选B。
17. A。句意：我喜欢周末，因为周六和周日我需要早起。need n’t不需要；mustn’t禁止；wouldn’t 不愿；shouldn’t 不应该。根据句意可知，周六、周日不用早起，故选A。
18. B。句意：这真是令人生气的；我不能进入你推荐的数据库。wouldn’t不愿意；couldn’t 不能；shouldn’t不应该；needn’t不必。故选B。

高中英语情态动词精讲与解析 概说 助动词(auxiliary)主要有两类：基本助动词(primary auxiliary)和情态助动词(modal auxiliary)。基本助动词有三个：do, have和be；情态助动词有十三个：may, might; can, could; will, would; shall, should; must, need, dare, used to, ought to. 上述两类助动词的共同特征是，在协助主动词构成限定动词词组时，具有作用词的功能： 1）构成否定式： He didn't go and neither did she. The meeting might not start until 5 o'clock. 2）构成疑问式或附加疑问式： Must you leave right now? You have been learning French for 5 years, haven't you? 3）构成修辞倒装： Nowhere can he obtain any information about his sister. Hardly had he arrived when she started complaining. 4）代替限定动词词组： A: Who can solve this crossword puzzle? B: Tom can. A: Shall I write to him? B: Yes, do. 情态助动词的特征 基本助动词与情态助动词最主要的区别之一是，基本助动词本身没有词义，而情态助动词则有自己的词义，能表示说话人对有关动作或状态的看法，或表示主观设想： What have you been doing since? （构成完成进行体，本身无词义） I am afraid I must be going. （一定要） You may have read some account of the matter. （或许已经） 除此之外，情态助动词还有如下词法和句法特征： 1）除ought和used以外，其他情态动词后面只能接不带to的不定式。如果我们把ought

情态动词 一、概述 情态动词表示说话人对某一动作或状态的态度，认为“可能、应当、必要”等等，但本身意义不完全，不能单独作谓语，必须和其他动词一起构成谓语。除ought, used, have后跟不定式外，其他情态动词一律跟动词原形。情态动词主要有：can/could, may/might, must, ought to, used to, need, dare, shall/should, will/would, have to等。 二、基本用法 （一）can和could的用法 1．表示能力，可译为“能，会”。 I can swim. 我会游泳。 Emily can dance well and her mother could dance well when she was young. The cinema can seat 1,000 people. I could not read such an easy book when I was 7 years old. 2．表示允许、许可，常用在口语中。could比can语气上要客气。 --- Could I use your dictionary? 我可以用一下你的字典吗？ ---Yes, go ahead. 可以，用吧。（或Yes, you can. 但不能说Yes, you could.） Could/ Can you tell me how to get to the zoo? 劳驾，你能告诉我怎么去动物园吗？ He asked me whether he could take the book out of the reading room. 3. 表示可能（理论上或是逻辑判断上）。 The temperature can fall to–60℃,that is60℃below freezing.气温可降至—60℃，也就是零下60℃。 You mustn′t smoke while you′re walking around in the wood.You could start a fire. 在林子里走时勿吸烟，那样可能会引起火灾。 3．表示推测，可用于肯定句（can罕见）、否定句和疑问句，但更常见于疑问句或否定句。在此种用法中can和could没有时态的区别，只是表示可能性的大小，can表示推测的可能性比could大。 Can he be ill at home? 他会是生病在家吗？ Can the story be true? 这个故事会是真的吗？

情态动词 情态动词是一种本身有一定的词义，但要与动词原形及其被动语态一起使用，给谓语动词增添情态色彩，表示说话人对有关行为或事物的态度和看法，认为其可能、应该或必要等。情态动词后面加动词原形。 情态动词有四类： ①只做情态动词：must,can(could),may(might)…… ②可做情态动词又可做实义动词：need，will ③具有情态动词特征：have(had,has) to,used to，ought to ④情态动词表猜测：一肯一否三不定（must一肯，can not一否，may，might，could，三不定。） 注：mustn't代表强烈禁止 must表示主观，have to表示客观。 常用的有：can may could must have use . 情态动词无人称和数的变化，情态动词后面跟的动词须用原形，否定式构成是在情态动词后面加 "not"。个别情态动词有现在式和过去式两种形式，过去式用来表达更加客气，委婉的语气，时态性不强，可用于过去，现在或将来。情态动词属非及物动词，故没有被动语态。 情态动词表推测的用法小结 （一）情态动词表推测的三种句式 1．在肯定句中一般用must （一定），can,could（可能），might /may（也许，或许）。 e.g:(1)He must/can/may,might know the answer to this question. 他一定/可能/也许知道这个问题的答案。 (2)It is cold in the room. They must have turned off the heating. 屋里很冷，他们肯定把暖气关了。 2．否定句中用can’t / couldn’t（不可能），may not/might not（可能不）。
