It ___41___ (build) originally to protect the city in the Tang dynasty and has now been completely restored (修复).…….We ___46___ (hire) our bikes from the rental place at the South Gate.【答案】41.was built 46.hired【解析】46.考查被动语态。
句意:它最初是为了保护唐代的城市而建造的,现在已经完全修复了。
分析句子可知,空格处为谓语,动词build和主语之间是被动关系,应用被动语态(be done),根据句意和时间状语the Tang dynasty可知,用一般过去时,谓语动词用过去式,主语it为第三人称单数,主谓一致,故填was built。
47.考查时态。
句意:我们从南门的租赁处租了自行车。
分析句子可知,此处为谓语动词,根据上下文可知,此处描述过去发生的事情,用一般过去时,谓语动词用过去式。
故填hired。
2.(2021年高考全国甲卷短文改错) They kept very much to themselves. In my opinion, whenever in trouble, we should seek help from those we trust most.考查时态。
句意:他们很自闭。
结合前文可知,文章的时态用一般现在时。
所以此处的kept改为keep。
高考英语情态动词语法专题训练(名师精讲必考语法知识点+实战真题,值得下载练习)一、情态动词的定义情态动词是一种本身有一定的词义,表示说话人的情绪、态度或语气的动词,但不能单独作谓语,只能和其他动词原形构成谓语。
情态动词数量不多,但用途广泛,主要有:can (could), may (might), must, need, ought to, dare (dared), shall (should), will (would) .二、情态动词的位置情态动词在句中放在谓语动词之前,谓语动词前若有助动词,则在助动词之前,疑问句中,情态动词放在主语之前。
•I can see you. Come here. 我能看见你,过来吧。
•He must have been away. 他一定走了。
•What can I do for you? 你要什么?•How dare you treat us like that! 你怎么敢那样对待我们!三、情态动词的语法特征1)情态动词不能表示正在发生或已经发生的事情,只表示期待或估计某事的发生。
2)情态动词除ought 和have 外,后面只能接动词原形。
3)情态动词没有人称,数的变化,即情态动词第三人称单数不加-s。
4)情态动词没有非谓语形式,即没有不定式,分词,等形式。
四、情态动词的用法(一). can; could; be able toCan 1. 表示“能力”(此时过去时是could) What can you do?2. 表示许可、请求,“可以”。
在口语中,can可以代替may表示许可,而may比较正式。
(此时用could 或might语气更委婉)--Can/Could I go now?--Yes, you can.3 表示推测(否,疑),把握很大,could也可表推测(肯,否,疑),把握比can小。
--Look! Someone is coming! Who can it be?--It can’t be him. He has gone to Paris.(不可能)He could be here soon. 他很快就来。
情态动词常见的情态动词有:can 能may 可以will,would (表意愿)need 需要dare 敢must 必须have to 不得不shall,should 应该(表义务)ought to 应该1.can,could 的用法1.1表能力,有“能”、“会”、“能够”的意思例如:Can you drive a car? 你会开车吗?-----Yes, I can. 我会。
-----No, I can't. 我不会。
1.2表允许,在口语中代替may,有“可以”的意思例如:Can I use your bike?我可以用你的自行车吗?1.3表示可能性,常用于否定句和疑问句例如:Can it be true?那会是真的吗?Today is Sunday. He can't be at school.今天是星期天。
他不可能在学校里。
1.4过去式could表示的语气更加委婉、客气例如:Could I come to see you tomorrow?明天我可以来见你吗?1.5 can 和be able to 的比较1) can 只有一般现在时和一般过去时两种时态(could),其他时态要用be able to的形式例如:I haven't been able to get in touch with her.我一直没能和她联系上。
2) 通常can 和be able to 可以互换例如:He will come if he can.如果可能的话,他一定会来。
2.may,might的用法2.1表示许可或征求对方的许可,有“可以”的意思。
例如:You may go now.你可以走了。
May I use your computer?我用一下你的电脑可以吗?2.2回答以may开头的疑问句有如下表达法:例如:May I smoke here? 我可以在这儿抽烟吗?-----Yes, you may.-----Yes, please.------No, you can't.------No, you mustn't.------No, you'd better not.2.3表示猜测,通常只用于陈述句例如:You may be right.你可能是对的。

The idea was to reunite Europe after the Second World War.At the same time, the “Fringe” appeared as a challenge to the official festival.Eight theatre groups turned up uninvited in 1947,in the belief that everyone should have the right to perform,and they did so in a public house disused for years.Soon,groups of studentsfirstly from Edinburgh University, and later from the universities of Oxford and Cambridge,Durham and Birmingham were making the journey to the Scottish capital each summer to perform theatre by little-known writers of plays in small church halls to the people of Edinburgh.Today the “Fringe”,once less recognized, has far outgrown the festival with around 1,500 performances of theatre,music and dance on every one of the 21 days it lasts. And yetas early as 1959,with only 19 theatregroups performing,some said it was getting too big.A paid administrator was first employed only in 1971, and today there are eight administrators working all year round and the number rises to 150 during August itself. In xx there were 200 places housing 1,695 shows by over 600 different groups from 50 different countries. More than 1,25 million tickets were sold.40.

To attract great artists from Europe.41. Why did some uninvited theatre groups e to Edinburgh in 1947?A. They owned a public house there.B. They came to take up a challenge.C. They thought they were also famous.D. They wanted to take part in the festival.42. Who joined the "Fringe" after it appeared?A.they owned a public house thereB. University students.C.人rusts from around the world.D. Performers of music anddance.43.
