新概念英语经典题_附答案

新概念英语经典题_附答案昨日习题： You have so much time. So you ________ worry. A mustn't B needn't C can't 答案：B解析：mustn't 表示绝对禁止needn't表示没必要can't 表示不能。根据句意可知：“你有如此多的时间，所以没必要担心." 所以应该选B. 今日习题：翻译：1. 我今天早上8：00 吃的早饭—————————————— 2. 我已经吃过早饭了。____________________ 今日习题：There _____ a dog and two cats in the gardon . A is B are C am D be 答案：A解析：本题考查There be句型，很多同学会误选B，而There be 句型有一个特殊的规定：“就近原则”，be动词后面是a dog 单数，所以选A is . 昨日习题：用a, an 填空.____ book _________apple _______ hour 答案：a an an 解析：填a 还是an . 是由后面单词的首个因素（音标）决定，而不是首个字母。最容易出错的是hour这个单词。它的音标是['a??]，从读音上可判断首个音标是一个元音音标，所以填an . mine .__________________

答案解析:首先特殊疑问句一般是：特殊疑问词+一般疑问句。第一题划线部分做的是The book 的定语，对定语的提问应该用which , 这里是which book. 再加一般疑问句，之前我们第一次练习题里面就有讲到一般疑问句，那四步骤。这里不再说。重点知道一变二（mine变yours）.第二题：我的书在桌子上，这里on the desk ，强调位置又做表语. 所以只能用where . 今日习题：(用所给词的适当形式填空)。I _________ (do my homework) now. 答案： am doing my homework解析：有时间是now，可以判断是现在进行时，而现在进行时态的结构是：be+doing ，因为主语是I,所以be 动词只能用am。最后答案是am doing my homework 今日习题：用many /much填空、 I have ______ books. I have _______ money. 答案：many ,much解析：many修饰可数名词，much修饰不可数名词. book是可数的，但是money在英语里面是不可数的。今日习题：用in front of / in the front of 填空。 The driver is ____________ the bus.（司机在车的内部） There is a tree _______________ the house.（树在房子的外部）答案：in the front of / in front of 解析：in the front of 是在。。。。内部的前面。in front of 是在。。。。。外部的前面。今日习题:You get 90 points, I get 60 points . You get ______ mistakes than I get. A. less B fewer C more D many 答案：B解析：Little 比较级是less. few比较级是fewer. little ,less 是修饰不可数名词，few fewer是修饰可数名词。你得了90分，我得了60分。所以你的错误比我的要少，又因为mistakes （错误复数）是可数的，所以选B.今日习题：I ______________ in two weeks .

新概念英语第3册第19课(汇编)

Lesson 19 A very dear cat 一条贵重的宝贝猫 Listen to the tape then answer the question below. Why was Rastus 'very dear' in more ways than one? Kidnappers are rarely interested in animals, but they recently took considerable interest in Mrs. Eleanor Ramsay's cat. Mrs. Eleanor Ramsay, a very wealthy old lady, has shared a flat with her cat, Rastus, for a great many years. Rastus leads an orderly life. He usually takes a short walk in the evenings and is always home by seven o'clock. One evening, however, he failed to arrive. Mrs. Ramsay got very worried. She looked everywhere for him but could not find him. Three days after Rastus' disappearance, Mrs. Ramsay received an anonymous letter. The writer stated that Rastus was in safe hands and would be returned immediately if Mrs. Ramsay paid a ransom of ￡1,000. Mrs. Ramsay was instructed to place the money in a cardboard box and to leave it outside her door. At first, she decided to go to the police, but fearing that she would never see Rastus again -- the letter had made that quite clear -- she changed her mind. She withdrew ￡1000 from her bank and followed the kidnapper's instructions. The next morning, the box had disappeared but Mrs. Ramsay was sure that the kidnapper would keep his word. Sure enough, Rastus arrived punctually at seven o'clock that evening. He looked very well though he was rather thirsty, for he drank half a bottle of milk. The police were astounded when Mrs. Ramsay told them what she had done. She explained that Rastus was very dear to her. Considering the amount she paid, he was dear in more ways than one! 1.dear adj. (dearer, dearest) 1. (~to sb.) loved by or important to sb. 亲爱的; 宝贵的；珍视的 e.g.（1）他是我最亲密的朋友之一。 He is one of my dearest friends. (2) 他的女儿是他心爱的宝贝。 His daughter is very dear to her. 2. (Dear) used at the beginning of a letter before the name or title of the person that you are writing to(用于信函抬头的名字或头衔前)亲爱的 3. [not usually before noun] (BrE)expensive; costing a lot of money 昂贵，价格高 e.g.现在什么东西都那么贵。 Everything is so dear now. n. 1. used when speaking to sb. you love (常作称呼所爱的人)亲爱的 e.g. 喝点什么吗，亲爱的？ Would you like a drink, dear? adv. (at a high price)高价地,昂贵地 e.g. (1) 他的错误使他付出很高的代价。 His errors cost him dear. (2) 贱买贵卖

新概念英语第二册课后题答案详解：Lesson19

新概念英语第二册课后题答案详解：Lesson19 新概念英语第二册课后习题 Lesson 19 1. a 根据课文第5-6行苏珊和售票处姑娘的对话：‘I’m sorry, we’ve sold out,’ the girl said. ‘What a pity!’ Susan exclaimed, 只有a. they had all been sold 与课文内容相符，而其他3个选择都与课文实际内容不符，所以选a. 2. d 根据课文最后一行‘I might as well have them,’ I said sadly(我还是买下为好，我垂头丧气地说。) 只有d. wasn’t too pleased to get tickets for next Wednesday’s performance 最能反映作者当时的心情，而其他3个选择都与课文实际内容不符，所以选d. 3. c 前一句The play may begin at any moment(剧马上就要开演了) 是对将要发生的事情的推测，只有c. hasn’t begun yet (它还没开演呢)是合乎逻辑的，也与前一句的内容相符合。而其他3个选择 a. has begun(已经开演了)不符合逻辑;b. won’t begin for a long time(好长一段时间后才开演)与课文意思不符;d. begun a long time ago(很久以前就开演了)更不符合题目意思和时态。 4. c 这是一个疑问句，需要用疑问句的语序，即主谓倒置， a. You must give me; b. You have got to give me 与 d. You may give me 这3个选择都是陈述句语序，只有c. Could I have 是疑问句语序，并且could 同前一句中的may 是一样的，都是表示“请求”的，所以应该选c.

学霸英语新概念第三册语法详解和总结(带习题和答案)

The death notices tell us about people who have died during the week. 2. The man (whom) you spoke to just now is my friend. 3. The building whose lights are on is beautiful. 4. Please find a place which we can have a private talk in. 5. The knee is the joint where the thighbone meets the large bone of the lower leg. 6. He still remembers the day when he went to school. 7. It is no need telling us the reason why you didn't finish it in time. 8. He has three sons, two of whom died in the war. 9. Mr. Smith, whose wife is a clerk, teaches us English. 10. In the Sunday paper there are comics, which children enjoy. 只能用that和who引导的定语从句 A．all, nothing, anything, a few, one做先行词指物时 B．先行词前有形容词最高级修饰时，后面常跟that而不是which. C．先行词前有the only, the first, the last, the next, the very等词修饰时，引导词只能用that。 D．当先行词是anyone, anybody, everyone, everybody, someone, somebody时，后面要用who或whom； ●All that glitters is not gold. 闪光的并非都是金子。 as 引导定语从句 as 引导的定语从句有两种形式： A．引导限制性语从句。在此类定语从句中，as常与主语中作为其先行词的such, the same或as联用构成，“such... as”，“the same... as”和“as ...as”句型，可代替先行词。例如：We hope to get such a tool as he is using. 我们希望得到他正在用的那种工具。 B．as 引导非限制性定语从句时，作用与which相同，as作为关系代词代替整个主句。（这是语法考试的一个考点。）［注意区别］： as 引导的从句用于句首、句中或句后，而which引导的定语从句不能放在句首。例如：As is reported, a foreign delegation will visit the city. 据报道，一个外国代表团将访问这个城市。二．状语从句超级作文联接词及词组，全部拿下！ ①原因：because, since, now that（既然）as, for, this reason.... ②结果：so that, so, therefore, consequently, so as to, as a result .... ③时间：after, before, when, while, as, until, as soon as, since, by the time, once, lately, presently, shortly after, currently, at present, nowadays ... ④条件：if, only if., once, unless, in the event (that), in case (that), provided that, on the condition that, etc.
