固定的动词短语look for：寻找（去掉for后look 没有寻找的意思，所以介词for不能前置）非固定的动词短语look at：注视live in：居住（去掉in后live 仍有居住的意思，所以介词in可以前置）This is the old house in which he lived. = This is the old house he lived in.is the road we came byis the pencil you were playing withMultiple choice questions 多项选择1…正确答案：Din common adv.共有（替换了similar）2…正确答案：BA）只是一个具体的特定的事列，阅读理解题的时候要把握中心大意B） large catpersuade v.说服, 劝说3…答案正确：C做理解题时要紧扣主题、紧扣中心大意文章最后一句话总结了大意句型结构题和词汇题是每课的关键4…答案正确：CMake的用法：make somebody do（在主动语态中不定式的符号to应该省略）be made to do（被动语态中不定式的符号to必须补充完整）-- They made her wait for hours. à She was made to wait for hours.5…答案正确： DA）把say改成claim就对了（-- People claimed to have seen the puma.）D）清楚的道明了动作发生的先后关系6…正确答案：B原句中的 when引导的时间状语从句表示：－...就…（as soon as）被动：On being observed, it immediately ran away.主动：On observing her, it immediately ran away.On seeing me, he waved to me.7…正确答案：Dexcept可以和名词/名词性从句进行搭配（也可是when/if引导的从句形式）unless = if...not = except on the condition that…when = if-- …except when they are cornered. = …except if they are cornered.-- Whenever you come, you are welcome. = If ever you come, you are welcome.8…正确答案：DA）must be只是对客观现实的推测，时态不一致-- 对于过去事实推测一定要用：情态动词+ have +过去分词9…正确答案：Con more than = nothing more than = only / within = not more than10…正确答案：Bin a corner 偷偷摸摸地, 暗中地, 秘密地in a trap 落于陷阱中at an angle 不正的, 倾斜的（angle n.角, 角度, 角落, 墙角, 棱角）under cover 在遮蔽处, 秘密地, 暗中11... 正确答案：Bfishes for pleasure 钓鱼消遣travel for pleasure 外出游玩read for pleasure 阅读消遣12…on one’s own adv.独自地, 独立地, 主动地（= alone）for one’s own benefit 为了某人自己的利益。
新概念英语第二册课后习题答案详解
新概念英语第二册课后习题答案详解Lesson 11. b选b最为正确。
因为a.d.都与课文内容不符合，也不合乎逻辑；c.的意思是“他们没有注意他”，而作者的意图并不是想让他们注意他，而是想让他们停止谈话。
所以选b. 最能表达作者当时心里的感受。
2．c其余3个答案都与原句意思不符合。
3．b因为a. to 不对，可以是He went to the theatre;c. into 也不对，可以是He went into the theatre;d. on更不符合语法，表示在某一个地方用介词in 或at, in 表示在大的空间，如国家，城市等，at 则表示在小的地点或空间，如atthe office, at the theatre 等, 所以选b.是正确的。
4．db. above(在……上方)；c. ahead of (在……的前面，在……之前)不和behind 对应，也不强调位置的前后顺序。
a. before 和d. infront of 都是和behind对应的，都有“在……前面”的意思。
但in front of 更具体的强调位置，而before则包含更宽泛的意思，即时间上，空间，次序，登记，重要性方面的“在……前面”5．c因为用 a. Where, b. why, d. when 提问都不符合逻辑，都不是针对状态提问的，只有How 提问，才能用Angry回答。
6．ab. they 只做主语； c. their只能做定语；d. us 虽然可以做宾语，但与前一句意思不符合。
7．da. none是代词，很少用在名词前面；b. any 只能用在否定句或疑问句中；c. not any 不符合语法，因为前面没有助动词did.8.ba. chair(椅子)， c. armchair(手扶椅) d. class(班级) 这3个选择都和seat的意思不符合。
Seat是”座位，座席”的意思。
强调的是可供坐下的地方，不是具体的椅子。

新概念英语第二册课后习题答案详解(96课全)
新概念英语第二册课后习题答案详解Lesson 31. c根据课文可以判断出作者不喜欢写明信片，但他很想收到别人寄来的明信片，所以应该选c.d. doesn’t like postcards 不喜欢明信片，和课文的含义不符合，所以不选d.2. a根据课文最后两句话可以判断出：作者作出的“一项重大决定”是给他的朋友们写明信片，可是还是一张没有写成，所以应该选a.3. ca. at 表示在小的地点和空间；b. to 表示方向；d. on 表示在……上；只有c. in 表示在大的空间和地方，如城市国家等，所以选c.4. a只有选a. Who taught ，这句问话才与回答相配。
5. d只有选d. in a friendly way(以友好的方式)才能说明前一句He was a friendly waiter,也合乎语法和逻辑。
而其他3个 a. friend(朋友)， b. as friends(作为朋友)，c. like friends(像朋友一样)在语法上都讲不通。

所以只有选b.7. ca. the hole 词意思不对；b. the ball 和 d. all of 不合乎习惯用法；英语中不用the all day, all of day 这样一来的短语。
只有选c. all 才能使句中的词组all day 同前一句中的the whole day 意思相同。
8. c句中的waiter 是“饭店服务员”的意思，他通常在饭店工作，而不在a. public garden(公园)，b. shop(商店)，d. private house(私宅) 工作，所以选c. restaurant.9. b只有b. borrowed 才与前一句中的lent相对应，而其他3个选择都不是。

新概念英语第二册课后练习题答案详解（第67课）
新概念英语第⼆册课后习题Lesson 67 1. d 根据课⽂第2-3⾏ In 1984, he went to lake Kivu in the Congo to observe a new volcano which 可以看出只有d. to investigate a new volcano (调查⼀座新⽕⼭)与课⽂的内容相符，其他3个选择都与课⽂的实际情况不符，所以选d. 2. a 根据课⽂第9-10⾏…but Tazieff managed to escape…He waited until the volcano became quiet and he was able to return two days later 可以判断，只有a. and Tazieff had to leave but he returned later 与课⽂的实际情况相符，其他3个选择都与课⽂的实际情况不符，所以选a. 3. d 前⼀句中的managed to 表⽰“成功地完成了的动作”，本句需要对这⼀动词作解释说明。
a. might have taken (本来应该做);b. could have taken (本来可以做);c. should have taken (本应该做);这3个选择含义相同都表⽰“过去该做，但却没做”，与managed to 含义不同。
只有d. succeeded in taking 与 managed to 意思相同，所以选d. 4. d 前⼀句he escaped just in time 意思为“他刚好及时逃离了。
”句中的just 是表⽰强调语⽓的副词，它的含义是“正好”，“勉强地”，本句是对前⼀句的进⼀步解释。
a. just only 的意思不通;b. only (只是，仅仅)与前⼀句含义不符;c. soon (不久，很快)与前⼀句意思不符;只有d. only just (只是勉强地)与前⼀句含义相符，所以选d. 5. d 该句的动词waited(等待)是不及物动词，后⾯只能跟for引导的短语。

研究生英语教材课后习题解答上册
Unit 1Text AExercises1. Reading comprehensionA. Read the text and answer the following questions.1. What, according to the author, do Americans love? Cite examples to illustrate your point.Americans love new frontiers. For example, they hanker after wide-open spaces; they like to explore; they like to make rules but refuse to follow them.2. Is there a place on earth where you can go and be yourself? What is the place according to the author?According to the author, there is a place—cyberspace, where you can go and be yourself.3. What metaphor does the author use to describe cyberspace? Why does she use such a metaphor?Real estate, because both real estate and cyberspace consist of different parts and each part is suitable for a particular group of people.4. Does the author approve of regulating cyberspace? Why or why not?Yes, but first, it is fundamental to understand the nature of cyberspace.5. What does the author think is needed in cyberspace besides government control?Self-rule.6. What are some of the main areas of cyberspace that the author defines?What other areas do you know that have recently emerged in cyberspace (e.g. e-business)?E-mail conversations, information and entertainment services, and cyberspace communities.7. How do cyberspace communities evolve? Give examples to illustrate your point.People of similar interests and tastes form a community. For example, communities on CompuServe tend to be professional; those on America Online are affluent young singles, and so on.8. What is unique about cyberspace rules? What authority do they have that rules in terrestrial environments don’t have?It allows communities of any size and kind to flourish. Cyberspace rules have moral authority that terrestrial governments don’t have.9. In what spirit are new communities formed?Communities cater to their own members’ inclination..10. What kind of government do explorers in cyberspace need?Their own local government besides terrestrial government does explorers.11. What should be done to deal with questionable items in cyberspace? Are people already doing that?We should be banning them and using labels and automatic filters to get rid of them. Yes.12. Is cyberspace a perfect place? If not, why are people so excited about it?No, it is not. People are excited about it because it offers a lot of information and freedom.B. Global understanding and appreciation of the text.1. Analogy (比喻，类推) is a figure of speech (修辞手段) which draws a parallel between two different types of things, and uses on (usually familiar to the reader) to explain reader’s understanding of the writer’s point. Can you draw a parallel between real estate and cyberspace? What point does the analogy support?The analogy between real estate and cyberspace2. By dividing cyberspace into three parts and using similes(明喻), the author defines the nature of cyberspace and illustrates further her point that government regulation is not needed in cyberspace. Complete the following form to show that you understand the author’s point. Please be reminded that the underlying structure of a simile is “A is like B”.3. In what way do the rules of a terrestrial government and those of a cyberspace community differ? Refer to para. 11 to answer the question.4. What is the language style of the article? Is it formal and literary or informal and conversational? Cite examples from the text to support your answer.This article is written in an informal and conversational style. For example, the author uses some slangy words, incomplete sentences, contractions, and addresses the reader as “you”.II. VocabularyA. Find a word or phrase from the paragraph indicated in the bracket that means the same as:1. in the past —→ formerly2. include —→ embrace3. man-made —→ artificial4. control systematically —→ regulate5. exactly —→ precisely6. undesired —→ unwanted7. irrelevant —→ extraneous8. having intense feeling —→ passionate9. aim toward —→ be targeted to10. not far away —→ at hand11. be charged for —→ be sued forB.

Each week he tried to set _____d____ a few dollars of his salary.a. forthb. aboutc. apartd. asideIII. ClozeChoose a proper word from the list to fill in each blank in the following passage. Change the form of the word if necessary:Born to SurfThe web From the Window contains poetry and literature from well-known writers across the global. There are thoughtful articles analyzing the state of the world we live in. There is (1)even a piece from the Secretary General of the United States, Kofi Annan. It may come (2)as some surprise to find out (3)that the editor of the magazine is a 12-year-old girl, Joy Nightingale. From the Window (4)won Joy Nightingale the first prize in the 1999 childnet Inter-national and Cable and Wireless awards. These are given (5)annually for the best use of the Internet (6)by and for young people. And (7)they highlight one of the most welcoming aspects of the (8)virtual world. Children have taken to the Internet as though they are born surfing.Perhaps this is (9)because adults have had to change their understanding of technology while children (10)simply accept it as natural. Whatever the reason, children can be found building websites and E-mailing friends (11)across the world while adults are (12)still asking: “Tell me again —where (13)exactly is cyberspace?”Of course there is growing (14)concern about the fact that children can travel far away from parental supervision in cyberspace. In (15)response , many parents have installed soft-ware packages which prevent (16)access to violent or pornographic websites. Childnet is taking a more positive line. The website is a gateway (17)to a world of education and entertainment.The rapid growth in Internet culture has (18)led analysts to speculate that society will soon be divided (19)between the “information rich”and “information poor”. For Childnet it is especially important that children at the margins of society through poverty or disability have the chance to take their (20)palce as equal citizens in the virtual world.IV. TranslationTranslate the following into Chinese:The possibility of a real market-style evolution of governance is at hand. In cyberspace, we’ll be able to test and evolve rules governing what needs to be governed — intellectual property, content and access control, rules about privacy and free speech. Some communities will allow anyone in: others will restrict access to members who qualify on one basis or another. Those communities that prove self-sustaining will prosper (and perhaps grow and split into subsets with ever-more-particular interests and identities). Those that can’t survive-either because people lose interest or get scared off-willsimply wither away.一种真正的市场型管理模式很快成为可能。

国际经济学课后习题答案
For personal use only in study and research; not for commercial use第一章1．为什么说在决定生产和消费时，相对价格比绝对价格更重要？答案提示：当生产处于生产边界线上，资源则得到了充分利用，这时，要想增加某一产品的生产，必须降低另一产品的生产，也就是说，增加某一产品的生产是有机会机本（或社会成本）的。
生产可能性边界上任何一点都表示生产效率和充分就业得以实现，但究竟选择哪一点，则还要看两个商品的相对价格，即它们在市场上的交换比率。
相对价格等于机会成本时，生产点在生产可能性边界上的位置也就确定了。
所以，在决定生产和消费时，相对价格比绝对价格更重要2．仿效图1—6和图1—7，试推导出Y商品的国民供给曲线和国民需求曲线。
答：参见教材第一章第二节容，将图1－6a中，以横坐标表示y商品的供给，以纵坐标表示x商品供给，得出相应生产可能性边界线，然后将图1－6b中，以横坐标表示y商品供给，以纵坐标表示y的相对价格，通过类似推导可得出国民供给曲线，国民需求曲线作类似推导可得。
3．在只有两种商品的情况下，当一个商品达到均衡时，另外一个商品是否也同时达到均衡？答：两种商品同时达到均衡。
一种商品均衡时，由其相对价格，机会成本，需求可知另一种商品得相对价格，机会成本和需求。
4．如果生产可能性边界是一条直线，试确定过剩供给（或需求）曲线。
答案提示：略，参见书上5．如果改用Y商品的过剩供给曲线（B国）和过剩需求曲线（A国）来确定国际均衡价格，那么所得出的结果与图1—13中的结果是否一致？答案提示：国际均衡价格将依旧处于贸易前两国相对价格的中间某点。
6．说明贸易条件变化如何影响国际贸易利益在两国间的分配。
答案提示：一国出口产品价格的相对上升意味着此国可以用较少的出口换得较多的进口产品，有利于此国贸易利益的获得，不过，出口价格上升将不利于出口数量的增加，有损于出口国的贸易利益；与此类似，出口商品价格的下降有利于出口商品数量的增加，但是这意味着此国用较多的出口换得较少的进口产品。
大学体验英语综合教程1课后习题及课文翻译
大学体验英语综合教程1课后习题及课文翻译A篇我在哈佛的第一周新生进入哈佛校园的第一天，据说总是令人激动不已。
这的确也是我来到哈佛第一天的真实写照。
父母陪着我开车驶过主校门进入校园时，那柔和的阳光透过绿树间隙照射在古老的砖墙建筑上。
沾满晨露的绿草在阳光下闪闪发光。
我凝视着车窗外面的迷人景色，心中暗想：“最幸运的新生不过如此了！”我们来到了卡纳迪公寓——我的宿舍楼。
我和四个女孩同住在四室一厅的套房里。
这个套房在顶楼，天花板很高，上面有天窗。
从卡纳迪公寓到餐厅和上课的教室，都只需要两分钟的路程。
我很喜欢自己的室友。
我们各自的背景、种族、宗教信仰和兴趣爱好都完全不同。
这也反映出哈佛引以自豪的“多样性”。
第一周，幸亏有这样四个可称为朋友的女孩相伴，帮助我顺利度过了到哈佛后的这段适应期。
这一周有许多重要的决定需要我来做，而没有父母和好友的帮助，有时我会感到十分艰难。
选课是第一步。
在哈佛，新生唯一的必修课是说明文写作。
这一年，我实际上可以选修我想学的任何课程，而且课程的门类出奇地多！我该如何选择呢？庆幸的是哈佛允许新生在“选课周”里到课堂试听。
上课时间和平时一样，我们可以试听任何想选修的课程，多少不限。
如果我最后决定选修某一门课程，我就要完成“选课周”里布置的所有功课。
另外，如果我试听了一门选课表上看似很好的.课程，却发现这门课并不适合我，或教授讲课枯燥乏味，我可以决定不选修这门课！同样艰难的是在众多的运动队、出版社团、乐队、戏剧社或俱乐部中做出选择。
到底该参加哪一个呢？在哈佛，就餐肯定也是最能引得新生关注的事情之一。
不过并不是指一日三餐吃的东西——尽管饭菜很可口，而是指就餐的环境真的很好。
我们的餐厅与其说是个自助食堂，不如说更像是一个教堂或博物馆。
桌子、椅子、地板、墙壁，还有高高的天花板都是用华丽的深色木料制作的，油漆得精光锃亮。
而且，大厅里悬挂着枝形吊灯，墙上镶嵌着明亮的彩色玻璃窗，厅里到处可见哈佛历史名人的雕塑和画像。
