Unit 3 A taste of En glish humouri •阅读理解A(2017课标全国n ,B)I first met Paul Newman in 1968, when George Roy Hill, the director of Butch Cassidy andthe Sundance Kid, introduced us in New York City. When the studio didn ' t want me for thefilm —it wan ted somebody as well known as Paul —he stood up for me. I don ' t know how many people would have done that; they would have liste ned to their age nts or the studio powers.The friendship that grew out of the experienee of making that film and The Sting four yearslater had its root in the fact that although there was an age differenee, we both came from a tradition of theater and live TV. We were respectful of craft(技艺)and focused on digginginto the characters we were going to play. Both of us had the qualities and virtues that are typical of America n actors: humorous, aggressive, and making fun of each other —but always with an un derly ing affectio n. Those were also at the core(核心、)of our relati on ship off thescree n.We shared the belief that if you ' re fortun ate eno ugh to have success, you should putsomething back —he with his Newman ' s Own food and his Hole in the Wall camps for kids who are seriously ill, and me with Sundance and the institute and the festival. Paul and I didn ' t see each other all that regularly, but shari ng that brought us together. We supported each other finan cially and by show ing up at even ts.I last saw him a few mon ths ago. He ' d bee n in and out of the hospital. He and I both knew what the deal was, and we did n ' t talk about it. Ours was a relati on ship that did n ' t n eeda lot of words.I. Why was the studio un willi ng to give the role to the author at first?A. Paul Newma n wan ted it.B. The studio power s did n ' t like his age nt.C. He was n' t famous eno ugh.D. The director recomme nded some one else.2. Why did Paul and the author have a last ing frien dship?A. They were of the same age.B. They worked in the same theater.C. They were both good actors.D. They had similar characteristics.3. What does the underlined word “ that ” in paragraph 3 refer to?A. Their belief.B.Their care for children.C.Their success.D.Their support for each other.4. What is the author ' s purpose in writing the text?A. To show his love of films.B. To remember a friend.C. To introduce a new movie.D. To share his acting experience.BA culture ' s values can be mirrored by its humor. Humor has been evaluated by many great minds such as Thomas Hobbes, who disliked humor, “ Laughter is nothi ng else but sudden glory arising from some sudden thought of feeling far better than others. ” He thought humor to bea negative quality of human narrow-mindedness.However, Mordechai Gordon, Ph.D. of Education, insists, “ Humor allows us to view the world f rom an angle that is amusing rather than serious. ” I agree with Gordon. Learning to lookat the world through humor is important.In the United States, every four years an election occurs. Without humor as a way to express their feelings, how else would Americans keep from clawing their eyes out and going the way of lemming?Television shows like“ The Daily Show ” have become important parts of American culture. They are mothering the masses by metaphorically (隐喻地) airplane-ing politics intoour mouths. They make politics fun.Of course, politics is only one type of humor. Social humor helps people through the twists and turns of the human condition. American pop culture promotes an unhealthy self-image. On the topic of self-image, Hari Kondabolu stands out. He has a joke about the popular musical group “The Pussycat Dolls ”, describing their hitsong “Don' t Cha ” as a negative representation of women. He points out an obvious offence in American culture.A study from Loyola Un iversity of Maryla nd has show n that humor is one determ ining factorfor selecting a mating partner. Amongst other things, mates look for an outstanding funny bonein a potential partner.Of course, humor is not always used for good purposes. Humor can be lin ked to vulgarity(庸俗)and racism, but, like everything else, it has potential to unite humanbeings by allowing us to laugh at ourselves, our failures and our connection with one ano ther.Though life may seem tough and depressing at times, all I have to do is look in the mirrorat my in creased wrin kles (皱纹)to know that there is a comedy out there that even Chapl in was n' t aware of.With that in mind, remember to laugh with huma nity and sometimes at huma ni ty.5. Hobbes believed that humor _________ .A. was only a way to laugh at others to make on eself feel betterB. resulted in n arrow-min ded ness of huma n beingsC. had the power to mirror personal glory and national valuesD. was for people to view the world from ano ther an gle6. What is the author ' s attitude towards political humor?A.Worried.B.Disappo in ted.C.Curious.D.Appreciative.7. The fourth paragraph is developed mai nly _____ .A.by exampleB.by processC.by comparis onD.by classificati on8. What can we lear n from the last two paragraphs?A.

(2)该实验分离细菌时用浓度为10-4和10-5土壤稀释液接种,更容易形成单菌落的是。

(3)A同学筛选出的菌落为150个,其他同学只筛选出50个,并且他在设计实验时并没有设置对照。

你认为A同学结果产生的原因可能有哪些?。

如何设计对照实验排除可能影响实验结果的因素:。

(4)涂布平板的所有操作怎样保证无菌?。

(5)有脲酶的细菌在生态稳态上起什么作用?。

答案(1)CO(NH2)2+H2O 2NH3+CO2(2)10-5土壤稀释液(3)可能是土样不同,也可能是培养基污染或操作失误方案有二:一是由其他同学用与A同学一样的土壤进行实验,如果结果与A同学一致,则证明无误,如果结果不同,则证明A同学存在操作失误或培养基配制有问题;另一种方案是将A同学配制的培养基在不加土样的情况下进行培养,作为空白对照,以证明培养基是否受到污染(4)应从操作的各个细节保证“无菌”,都应在火焰附近进行。

例如,酒精灯与培养皿的距离要合适、移液管头不要接触任何其他物质、移液管要在酒精灯火焰周围等(5)如果土壤中有许多尿素,在自然界较高温度下会被水解,水解后的氨使土壤碱化,氨还与其他阴离子物质如S、C、N等形成化合物,则会使土壤板结。

有脲酶的细菌使植物废弃物和动物尸体降解,并利用了所形成的氨,有利于自然界中氮的循环解析脲即尿素,是蛋白质降解的产物。

有一些细菌含有脲酶可以分解尿素,利用尿素作为其生长的氮源。

本实验使用涂布分离法分离以尿素为氮源的微生物,用浓度为10-4和10-5土壤稀释液接种,更容易形成单菌落的是10-5土壤稀释液。

A同学结果产生的原因可能是土样不同,也可能是培养基污染或操作失误,排除方案有二:一是由其他同学用与A同学一样的土壤进行实验,结果与A同学一致,则证明无误,如果结果不同,则证明A同学存在操作失误或培养基配制有问题;另一种方案是将A同学配制的培养基在不加土样的情况下进行培养,作为空白对照,以证明培养基是否受到污染。

Unit 2 Section ⅣⅠ.阅读理解America is a mobile society.Friendships between Americans can be close and real, yet disappear soon if situations change.Neither side feels hurt by this.Both may exchange Christmas greetings for a year or two, perhaps a few letters for a while —then no more.If the same two people meet again by chance, even years later, they pick up the friendship.This can be quite difficult for us Chinese to understand, because friendships between us flower more slowly but then may become lifelong feelings, extending (延伸) sometimes deeply into both families.Americans are ready to receive us foreigners at their homes, share their holidays, and their home life.They will enjoy welcoming us and be pleased if we accept their hospitality(好客) easily.Another difficult point for us Chinese to understand Americans is that although they include us warmly in their personal everyday lives, they don’t show their politeness to us if it requires a great deal of time.This is usually the opposite of the practice in our country where we may be generous with our time.Sometimes, we, as hosts, will appear at airports even in the middle of the night to meet a friend.We may take days off to act as guides to our foreign friends.The Americans, however, express their welcome usually at homes, but truly can not manage the time to do a great deal with a visitor outside their daily routine.They will probably expect us to get ourselves from the airport to our own hotel by bus.And they expect that we will phone them from there.Once we arrive at their homes,the welcome will be full, warm and real.We will find ourselves treated hospitably.For the Americans, it is often considered friendly to invite a friend to their homes than to go to restaurants, except for purely business matters.So accept their hospitality at home!语篇解读:本文是一篇说明文。

UNIT 4 Section ⅣⅠ.阅读理解On July 11th Virgin Galactic finally realized the promise that it would take passengers on life-changing trips in its spaceships.For 4 minutes,its six temporarily weightless passengers,including the firm's co-founder,Sir Richard Branson,saw the planet's curvature (曲度) against the blackness of outer space.He may have gloated (窃喜) over beating Jeff Bezos(much richer),Amazon's retired boss,who would go slightly higher,for slightly less time,in a vehicle built by his own company,Blue Origin,on July 20th.The two are among a growing group of enthusiasts who believe space tourism's time has come.Suborbital (亚轨道) tourism is part of a broader space economy that has boomed over the past decade thanks to technological advances.Those at Morgan Stanley expect the entire space economy to generate$1trm in revenue by 2040,from $350bn today.UBS (瑞银集团) expects the entire space economy to produce $800 billion by the end of this decade.Space tourism,it thinks,will make “a big contribution” to that total.But that is highly unlikely.For example,space tourism is not even Blue Origin's main goal.The company is focusing on developing a large new rocket for launching satellites,on selling advanced rocket engines to other companies and on winning NASA contracts such as that for a system to land humans on the Moon.In the long run,Mr. Bezos doesn't see Blue Origin as provider of services to thrill-seekers.The business could be profitable once regular flights begin to offset (抵消) the rockets' development costs.But how fast and by how much is uncertain.Without tourist-friendly destinations to visit,space tourism,with its far higher ticket prices,will not be a huger earner.Another challenge—and the biggest uncertainty—relates to safety.History has shown that a disaster can set progress back by years.Even with no accidents,problems may arise.Strict top down regulation could mean that industry will no longer have the freedom to pursue new approaches to improving safety.Space tourism may remain a hobby for a few superrich with a desire to take risks and lots of time to spare.Not exactly a mass market,then,for the time being.文章大意:本文是一篇新闻报道。

The city discovered its harbor. Then, one after another, Sydney discovered lots of things that were just sort of there—broad parks, superb beaches, and a culturally diverse population. But it is the harbor that makes the city.Andrew Reynolds,a cheerful fellow in his early 30s, pilots Sydney ferryboats for a living. I spent the whole morning shuttling back and forth across the harbor. After our third run Andrew shut down the engine, and we went our separate ways—hefor a lunch break,I to explore the city.“I’ll miss these old boats,” he said as we parted.“How do you mean?”I asked.“Oh, they’re replacing them with catamarans. Catamarans are faster, but they’re not so elegant, and they’re not fun to pilot. But that’s progress,I guess. ”Everywhere in Sydney these days, change and progress are the watchwords(口号), and traditions are increasingly rare. Shirley Fit zgerald, the city’s official historian, told me that in its rush to modernity in the 1970s, Sydney swept aside much of its past, including many of its finest buildings. “Sydney is confused about itself,”she said. “We can’t seem to make up our minds whether we want a modern city or a traditional one. It’s a conflict that we aren’t getting any better at resolving(解决). ”On the other hand, being young and old at the same time has its attractions.I considered this when I met a thoughtful young businessman name d Anthony. “Many people say that we lack culture in this country,”he told me. “What people forget is that the Italians, when they came to Australia, brought 2000 years of their culture, the Greeks some 3000 years, and the Chinese more still. We’ve got a fo undation built on ancient cultures but with a drive and dynamism of a young country. It’s a pretty hard combination to beat. ”He is right, but I can’t help wishing they would keep those old ferries.文章大意:本文是一篇夹叙夹议文。

It was after I saw an advertisement in a newspaper looking for people to join a team to ski 350 miles to the North Pole.

The words “Are you man enough for the ultimate(极限的) challenge?” made me angry and even more determined to get on the team.Over 500 individuals applied for a place in the team, and the selection process included physical and psychological tests designed to pick the best group. In one test, there was a huge rope ladder we had to climb, and I froze at the top because I have a fear of heights. I thought my hopes were fading as most other applicants sailed past, leaving me behind. But two others helped me over, and later I found out that the organizers were not looking for amazing individuals, but great team players, and this moment had shown them who would take care of others in the team.I had revealed(显示) my weakness, and in a place like the Arctic, you have to be yourself, as there is nowhere to hide. These personalities of asking for help and showing weakness are necessary for women to master.I realized that by being myself,I could succeed. I was selected for the team.I realized that I could achieve more than I ever imagined—more importantly, by sharing my story with others,I could inspire them to take a step into the new world and reveal more of their abilities.文章大意:本文是一篇夹叙夹议文。

有的生物学家强调技术的不足易导致严重后果,这显然属于反对克隆人的科学家的观点。

2.下列说法,正确的是( A )A.克隆人在理论上是可行的B.在医学上,通过遗传病基因检测后,进行胎儿性别的选择也是违法的C.治疗性克隆和生殖性克隆是一回事D.用于器官移植时,可以克隆人解析:医学上对遗传病基因检测后选择胎儿性别,目的是优生;生殖性克隆的目的是产生人类个体,任何情况下都是禁止的;治疗性克隆的目的是产生特定细胞和组织用于治疗疾病。

3.一对夫妇将用他们精、卵结合后发育成的胚胎冷藏在一所不孕症治疗中心(防止胚胎移植不能一次成功时,以备下次再用)。

在一次外出时,他们因飞机失事而去世。

于是有人提出,是不是应该把胚胎植入代孕母亲子宫,生下一个孩子继承遗产?还有人认为没有这个必要,可以把财产交给他们的亲戚,或交给国家处理。

这件事反映了“胚胎冷藏”技术( B )A.是对人类生育权的保护B.可能带来伦理问题C.是一种成熟的可推广的技术D.是一种国家法律所禁止的技术解析:“胚胎冷藏”技术所引起的这些争论,实质是冷冻胚胎的道德与法律地位的争论,即带来的伦理问题。

4.一些国家通过的生物伦理法案,从立法上禁止进行生殖性克隆和治疗性克隆,明文禁止从事治疗性克隆研究的原因是( B )A.治疗性克隆带来严重后果B.治疗性克隆的研究很可能会过渡到生殖性克隆C.治疗性克隆严重违反伦理道德观念D.治疗性克隆就是生殖性克隆解析:人类生殖性克隆的研究严重混淆了伦理道德观念,所以被绝对禁止,而治疗性克隆的研究很可能会过渡到生殖性克隆的研究,所以明文禁止从事治疗性克隆研究。
