高考情态动词讲解及练习

高考超实用情态动词练习题附详解题库一、单项选择情态动词1．While it wasn’t the goal of the trip, I was rewarded with fresh insights, ones that ________ to me during the regular course of business.A．might never happen B．could never have happenedC．should not happen D．needn’t have ha ppened【答案】B【解析】【详解】考查虚拟语气。

句意：虽然这并不是这次旅行的目的，但我得到了一些新的领悟，那些领悟在我的日常生活中是本不可能发生的。

此处考查虚拟语气，“我得到新的领悟”发生在过去，故此处是与过去事实相反，应用could/might/would/need/should+have done，“本不可能发生”是could never have happened，故选B项。

【点睛】本题考查“情态动词+have done”的虚拟语气，其常用表达有：could have done本能做某事而未做couldn’t have done不可能做了某事should have done本应该做某事而未做shouldn’t have done本不应该做某事而做了would have done本会某事而未做wouldn’t have done本不会做某事而做了need have done本需要做某事而未做needn’t have done本不必要做某事而做了2．They were abroad during the months when we were carrying out the investigation, or they __________to our help.A．would have come B．could comeC．have come D．had come【答案】A【解析】试题分析：本句考查的是一个含蓄的虚拟条件句，句中的or相当于if they had not gone abroad.因为前面句中使用的是were，说明这个虚拟语气是与过去事实相反，所以主句中使用的是“情态动词+have done”的形式。

考点讲解：概述情态动词（Modal Verbs）是用来表示能力、允许、预言、可能性、建议、情感、态度等的含义的一类动词。

我们使用缩写modal v.来表示情态动词。

情态动词属于不完全动词，因此情态动词不能独自在句中作谓语，即其后需要一个实义动词和情态动词共同在句中作谓语。

这样的谓语一般也称作“复合谓语”，属于复合谓语中的一种类型。

一般地，情态动词后面接不带to的动词不定式，即动词原形。

一般地，情态动词具有助动词的语法属性，可以完成一些语法功能的需要（比如可以构成否定句或疑问句等）。

有一些情态动词有相应的过去式的形式，有一些则没有（如must 等）。

句意：“昨晚10点左右你给我打了电话，是吗？”“不，我没给你打电话。

一定是别人干的。

” must have done 是对过去发生的动作最有把握的猜测，意思是“一定”，结合语境可知，我没有打电话给你，因此猜测一定有别人给你打了电话。

故选A 项。

3．Mr. Baker, some students want to see you. ______ they wait here or outside?A．May B．Should C．Shall D．Will【答案】C【解析】【详解】考查Shall的用法。

句意：贝克先生，有些学生想见你。

他们是在这里等还是在外面等?Shall用于第一、第三人称疑问句中，表示说话人征求对方的意见或向对方请示。

故选C。

【点睛】Shall的用法Shall作为助动词，一般用于第一人称Ⅰ和We，表示一个将来的动作，构成将来时态。

高中英语语法专攻-《情态动词》【考点1-can&could】·can和could 表推测对现在或将来的推测，两者均可用，但can 通常只用于否定句或疑问句中，一般不用于肯定句，而could则可用于肯定句、否定句和疑问句；对过去的推测，应在can,could 之后接动词的完成式，且此时can仍只用于否定句或疑问句，不用于肯定句；而could 则可用于各种句型。

如：Can [Could] this be true? 这能是真的吗Where can [could] he have gone? 他能到哪里去了呢She can’t [couldn’t] have left so soon. 她不可能走得这么早。

He could have gone home. 他可能已回家了。

【注：could后接动词的完成式，除表示对过去的推测外，还可表示过去没有实现的可能性（即某事本来可以发生，却没发生），或委婉地责备某人过去应该做某事而没有去做（此时不用can）。

】如：You could have started a little earlier. 你本可早点动身的。

You needn’t have co oked it. We could have eaten it raw.你其实可以不煮熟（它），我们（本来）可以生吃。

·can和could表允许表示现在的允许时，若是请求别人允许自己做某事，两者均可用，但用could 语气更委婉；若是自己允许别人做某事，一般只用can，而不用could。

如：Can [Could] I come in? 我可以进来吗“Could [Can] I use your pen? ” “Yes,of course you can.”“我可以借用你的钢笔吗?”“当然可以。

”（不能说Yes,you could.)表示过去的允许时，若表示过去一般性允许（即表示某人随时都可以做某事），用could；若表示在过去某一特定情况下允许进行某一特定的活动，则不用could。

【英语】高中英语情态动词解题技巧及练习题及解析一、单项选择情态动词1．—________ the woman with the baby come over? We have a seat here.—Thank you, sir. Actually I do have my seat here. But my baby likes to look out of the window. A．Would B．ShallC．Must D．May【答案】A【解析】【详解】考查情态动词。

句意：——那位抱小孩的女士，要不来这边吧?这儿有个座位。

——谢谢，实际上我有座位的，只是我的孩子喜欢看窗外。

would表示婉转的请求，征求对方的意见，Shall提问一般只用于第一人称，我们常说Shall I.或者 Shall we；may表示请求对方允许。

故选A。

【点睛】would的用法1.would 最常见的用法是：相对于一个过去时间点的后来“将要”做什么，比如：He said he would meet me at the station. 他说他会在车站接我的。

这句中的 would meet 是相对于 said （过去说）之后要做的事情。

又如：She thought she would have to ask someone for help. 她当时想，她得找个人帮忙。

2．—You rang me up at about 10:00 last night, didn't you?—No, I didn't phone you. It someone else.A．must have been B．could be C．must be D．could have been 【答案】A【解析】【详解】考查情态动词+have done。

句意：“昨晚10点左右你给我打了电话，是吗？”“不，我没给你打电话。

一定是别人干的。

高中英语情态动词常见题型及答题技巧及练习题(含答案)一、单项选择情态动词1．The professor warned the students that on no account ________ use mobile phones in his class.A．should they B．they shouldC．dare they D．they dare【答案】A【解析】【详解】考查部分倒装和情态动词。

句意：这位教授警告学生们，在他的课堂上，决不应该使用手机。

on no account意为“决不”，否定词放在句首，句子使用部分倒装，排除B、D项；这里表示应该，故选A。

2．—Did you attend the meeting for the experiment project yesterday?—Yes, but I don’t think I ____ because my director was there.A．need to have B．need to C．needed to D．need have【答案】D【解析】【分析】【详解】考查情态动词+have done。

句意：——你昨天参加实验项目的会议了吗?——是的，但我想我（本来）不需要，因为我的主管在那里。

Think/suppose等宾语从句中如果有否定词时，要把从句的否定词not前移，即“否定前移”。

所以not是从句中的否定词。

“need have done”意为“本来有必要做而未做”；“needn’t have done”指过去本来没必要做而做了。

根据上一句时间状语“yesterday”可知本句指的是过去发生的事。

结合第二句“because my director was there(我的主管)在”可推断出，我本来不必要去。

故选D。

3．We ________ take clean drinking water for granted. One day we may run out of it. A．needn't B．can'tC．won't D．shouldn't【答案】D【解析】【详解】考查情态动词。
