Unit 2 CloningⅠ.阅读理解(共10小题;每小题2。

5分,满分25分)AEven at school there had been an unhealthy competition between George and Richard.“I’ll be the first millionaire in Coleford!" Richard used to boast.“And you'll be sorry you knew me,” George would reply “because I'll be the best lawyer in the town!”George never did become a lawyer and Richard never made any money.Instead both men opened bookshops on opposite sides of Coleford High Street.It was hard to make money from books, which made the competition between them worse.Then Richard married a mysterious girl。

The couple spent their honeymoon on the coast-but Richard never came back。

The police found his wallet on a deserted beach but the body was never found.He must have drowned。

Now with only one bookshop in town, business was better for George。

But sometimes he sat in his narrow, old kitchen and gazed out of the dirty window, thinking about his formal rival。

a lifestyle—choice among young people across Asia、Some kidults collect toys they once played with、 Hello Kitty, Garfield, and Snoopy have many adult fans around the world、 It is not unusual to see a 20-something woman with a big, Garfield-shaped cushion on her sofa or a Hello Kitty mobile phone accessory、Other kidults still enjoy children's stories and fairy tales、For example, Bloomsbury even published the Harry Potter novels with an adult cover、 That way, no one else on the subway will know that an adult is actually reading a children’s book!”Kidults can be like vitamins to society、 Adults who value their childhood and hold on to pure, child-like emotion may be needed in such a rough and dry society," said Lee Sojung, professor of Foreign Studies at Hankuk University(韩国外国语大学)、 He added that kidult culture may fill the generation gap between adults and kids、 It could give children and their parents books, movies, and cartoon shows to enjoy together、 He may be right、Tim Greenhalgh,a professor,explained that some kidults just refuse to grow up、They value childhood because life in a busy and stressful city frightens them、Kidults would like to forget their age and openly show their fear of society and adulthood、56、 We can infer from the article that _________、A、 Kidults miss their childhood so much that they can’t give up their toysB、 Bloomsbury knows some kidults don’t want people to know that they are kidultsC、 Kidults like to have vitamins very muchD、 Some toys are so interesting that even adults like them very much57、 According to the author, being a kidult is good in some way except that _______、A、 it can improve the relationship between parents and their kidsB、 it can help kidults feel relaxedC、 it is helpful to solve some social problemsD、 it can make people loyal to one's parents58、 According to the writer, _______、A、 being a kidult is nothing wrongB、 kidults have mental problemsC、 our society is very dullD、 some people can never grow upBIf women are mercilessly exploited(剥削) year after year, they have only themselves to blame、 Because they tremble at the thought of being seen in public in clothes that are out of fashion, they are always taken advantage of by the designers and the big stores、 Clothes which have been worn only a few times have to be put aside because of the change of fashion、Changing fashions are nothing more than the intentional creation of waste、 Many women spend large sums of money each year to replace clothes that have hardly been worn、 Women who cannot afford to throw away clothing in this way, waste hours of their time changing their old-fashioned dresses、 Skirts are lengthened or shortened; neck-lines are lowered or raised, and so on、No one can claim that the fashion industry contributes anything really important to society、 Fashion designers are rarely concerned with necessary things like warmth, comfort and durability (耐用)、 They are only interested in outward appearance and they take advantage of the fact that women will put up with any amount of discomfort,as long as they look right、 There can hardly be a man who hasn't at some time in his life smiled at the sight of a woman shaking in a thin dress on a winter day, or picking her way through deep snow in high heeled shoes、When comparing men and women in the matter of fashion, the conclusions to be drawn are obvious、 Do the constantly changing fashions of women’s clothes, one wonders, reflect basic qualities of inconstancy and instability? Men are too clever to let themselves be cheated by fashion designers、 Do their unchanging styles of dress reflect basic qualities of stability and reliability(稳定耐用)? That is for you to decide、59、 Designers and big stores always make money_________、A、 by mercilessly exploiting women workers in the clothing industryB、 because they are capable of predicting new fashionsC、 by constantly changing the fashions in women’s clothingD、 because they attach great importance to quality in women’s clothing60、 To the writer, the fact that women change their old—fashioned dresses is seen as ___________、A、 a waste of moneyB、 a waste of timeC、 an expression of tasteD、 an expression of creativity61、 New fashions in clothing are created for ___________、A、 the commercial exploitation of womenB、 the women's strength of characterC、 basic qualities of inconstancy and instabilityD、 an important contribution to society62、 By saying "the conclusions to be drawn are obvious" ( Line One to Line Two,Paragraph Four), the writer means that ___________、A、 women's inconstancy in their choice of clothing is often laughed atB、 women are better able to put up with discomfortC、 men are also exploited greatly by fashion designersD、 men are more reasonable in the matter of fashionCWhile football fans feel strongly angry and shocked about mistakes made by referees (裁判) because they cannot see clearly what has happened, a small German company is quietly pleased、For Cairos Technologies, mistakes made by referees are the kind of advertising that money cannot buy、 The company has developed a tiny chip(芯片) that fits inside a football and determines whether the ball has crossed the goal line, by being able to discover its exact location on the field、 The world football organization, FIFA,has shown interest in the technology、 It is very possible that the new technology will be used in the 2006 World Cup in Germany、”We’ve been testing the technology at the main soccer stadium in Nuremberg for some time and more recently in an under—17 FIFA Cup in Peru,” said Gunter Rohmer, a director of the company、”The technology has performed well, and we’re pretty optimistic that it will be used at the games in Germany next year、"The chip only weighs 12 grams, and is placed in the center of the football、 It sends 2,000 signals a second to a receiver network of 12 antennas(天线),placed around the field、 The receivers then send information about the ball's location to a central computer, and because it works in real time, it can immediately tell the referee whether a goal has been scored、 The chip even can tell when the ball crosses the line in mid-air、 Oliver Braun, one of the inventors of the chip, says that feedback from German referees was generally positive、 Germany sports-wear giant Adidas is also optimistic about using this kind of chip in other ball sports、FIFA aims to test the technology later this year at another game in Japan before deciding whether or not to introduce it in all 12 stadiums in Germany for next year’s World Cup、63、 Carlos Technologies is pleased because ________、A、 football fans are angry with refereesB、 their new product can satisfy football fansC、 their new product will have a good marketD、 they can sell a lot of football in the future64、 In the first sentence in Paragraph 2,”、、、 mistakes made by referees are the kind of advertising that money cannot buy” means ___________、A、 Carlos Technologies can’t afford the high price for advertising their productB、 Mistakes in production are also a kind of advertisementC、 Carios Technologies has already spent a lot of money on advertising their productD、 Referees' mistakes will be of great help for the sale of Carlos Technologies’new product65、 The underlined word "feedback” probably means ___________、A、 information given back by a userB、 advice given by someoneC、 supplying food to customersD、 food given back by consumers66、 The new product has drawn attention from some _________、A、 famous peopleB、 refereesC、 big companiesD、 countriesDLondon—-A morning train rides away, across the channel、 English kids discuss theLiverpool's football team in a Paris pub、Some Parisians have started to travel to work in London、In the 19th century, Charles Dickens compared the two cities, London and Paris,in A Tale of Two Cities、 These days, it might be A tale of One City、As there are few jobs at home over recent years, perhaps 250,000 Frenchmen moved across the channel、 With an undersea tunnel, they could travel between cities in three hours、 The European Union freed them from immigration and customs、Paris, rich in beauty, is more stylish、 But London feels more full of life, and more fun until the pubs shut down、”For me, the difference is that London is real, alive,” said Trevor Wheeler,a financial expert、Chantal Jaouen, a professional designer, agrees、”I am French, but I'll stay in London,’' she said、There is, of course, the other view、 Julie Lenoux is a student who moved to London two years ago、”I think people laugh more in Paris," she said、”Both cities have changed beyond recognition," said Larry Collins, an author and sometimes a Londoner、Like most people who know both cities well, he finds the two now fit together comfortably、"I first fell in love with Paris in the 1950s、 Things are so much more ordered, and life is better、”But certainly not cheaper、In some parts of London, rents can be twice those on Avenue Foch in Paris、Deciding between London and Paris requires a lifestyle choice、Like Daphne Benoit, a French journalism student with perfect English, many young people are happy to be close enough so they don't have to choose、”I love Paris, my little neighbourhood, the way I can walk around a centre, but life is too organized , ”she said、 "In London, you can be whoever you want、 No one cares、"67、 It can be inferred that ___________、A、 Paris and London are the two biggest cities in the worldB、 in the 19th century, Dickens told his stories in the two citiesC、 London and Paris used to be separatedD、 Liverpool is a big city in France68、 According to this passage, which of the following is TRUE?A、 People feel it difficult to find a job in Paris、B、 People can't travel to London without a passport、C、 People can travel to London without a passport、D、 People can find any job in London、69、 According to this passage we know that _________、A、 Parisians enjoy English food more than their ownB、 Londoners seldom travel to Paris on holidaysC、 both cities have their advantagesD、 young people prefer to live in London70、 Which city is better to live in according to the passage?A、 Paris、B、 London、C、 Both cities、D、 It just depends、71、 What’s the meaning of the last sentence?A、 People can do everything in London、B、 People will feel lonely in London、C、 People in London enjoy living in different ways、D、 People in London enjoy a lawless life、ENow let’s look ourselves as a species in relation to ecosystem balance、Modern scientists believe that humankind, like other animals, evolved(进化)through millions of years of changes and adaptations to the environment and that our most direct evolutionary ancestor was probably an earlier species of the primate(monkey, ape) group、 Despite this similarity with other creatures, however,the evolution of humankind differs from that of other species in one important and unique way、In other species, evolution has led to specialization, both in the species abilities and in its place within the environmental structure、 For example, the giraffe is much adapted to feeding on treetops, but it is also specialized and thus limited to feeding on trees and shrubs、 Only with great difficulty can it bend down to graze on the ground、 Similarly, the anteater is extremely well adapted to eating ants but is unable to catch or eat other animals、 The same is true for countless other species、For humankind it is opposite、 Our evolution had led to a very generalized ability、Our highly developed intelligence and ability to make and handle tools mean that we can do almost anything、 Humans evolved in such a way that we are able to move into every environment on Earth and even into space、 No natural competitor offers great resistance, and other natural enemies such as disease have been controlled、Said another way, we see in humankind a great imbalance between biological potential and environmental resistance、 The result is the rapidly increasing world population, frequently referred to as the population explosion、 Further, to support our growing population, natural ecosystems are being increasingly displaced by human habitations, agriculture, and other human supporting activities、72、 From the passage we can infer that in the course of evolution _________、A、 humankind is very important to earlier species, such as the primate groupB、 human beings are limited by the environment while animals are notC、 human beings become more and more different from each otherD、 humankind has experienced a generalization rather than specialization in ability73、 According to the passage, primate includes such animals as ________、A、 monkeys and anteatersB、 tigers and apesC、 apes and monkeysD、 monkeys and giraffes74、 According to the passage, evolution has made it possible for humans to _______、A、 increase the populationB、 resist natural offersC、 go to the moonD、 cure all diseases75、 According to the author, imbalance between biological potential and environmental resistance has resulted in ________、A、 the population explosionB、 the destruction of human habitationsC、 the growth of natural ecosystemD、 the specialization of humansIV 短文改错此题要求改正所给短文中的错误。

人教新课标高中英语选修八 Unit2 Cloning~ Unit3 培优训练卷(含答案)

人教版高二下学期培优训练卷选修八Unit2 Cloning ~ Unit3 Inventors and inventions 一、阅读理解AAs if there weren’t enough of them in the world already, scientists have succeeded in cloning flies. The alike fruit flies are the first insects ever cloned, says the Canadian team that created them. The question everyone asks is why anyone would want to clone flies in the first place. She hopes that the insects, which are very easy to experiment with, will help to adjust the cloning process in other animals and even in humans, where the technique is being researched to aid production of therapeutic(治疗的) stem cells.In cloning, the DNA-containing nucleus(细胞核) of an adult cell is injected into an egg whose own nucleus has been removed. At the moment, the majority of cloned mice, sheep and other animals die before birth. It is thought this is because the adult DNA is not properly ‘reprogrammed’.Using flies, researchers might discover genes that are important for this reprogramming, and that have matches in other animals. That is because it is relatively easy in flies to knock out the function of a single gene and then attempt cloning with these cells, which will test whether that gene is important. If such genes are confirmed, then in theory cloned mammalian embryos(晶胚) might be grown in selected solutions that change the activity of those genes to improve the technique’s success rate. Although some groups have attempted to clone insects before, Lloyd says this is the first time it has been successful. The team used a slight difference on the standard cloning process: they transferred nuclei taken from embryos rather than fully-grown adult cells. They sucked several nuclei out of developing fly embryos, and injected them into a fertilized(已受精的) fly egg. From over 800 early attempts, they cloned five adult insects, the group reports in the journal Genetics.1. The best title of this passage probably is .A. The importance of cloneB. The first cloned insectC. The disagreement in cloneD. The advantages of clone2. The scientists cloned flies because .A. there are fewer and fewer flies in the worldB. flies are easy to find and cheap to useC. they can gain some experience before cloning other animalsD. it is safe to clone flies3. The failure of most cloned animals is due to .A. the difference of other animals’ genesB. the improper technique of cloneC. the complexity of other animalsD. the improper rearrange of the adult gene4. It can be inferred from the last paragraph that .A. the clone of insects before used grown-up cellsB. the clone of insects were never experimented beforeC. this time scientists cloned flies successfully and easilyD. based on this success, other animals will be cloned in large quantities.BTraditionally, robots have been hard, made of metal and other rigid material. But a team of scientists at Harvard University in the US has managed to build an entirely soft robot — one that draws inspiration from an octopus(章鱼).Described in science journal Nature, the “Octobot” could pave the way for more effective autonomous robots that could be used in search, rescue and exploration. “The Octobot is minimal system which may serve as a foundation for a new generation of completely soft, autonomous robots,” the study’s authors wrote.Robots built for precise, repetitive movements in a controlled environment don’t do so well on rough terrains(地形) or in unpredictable conditions. And they aren’t especially safe around humans, because they’re made out of hard and heavy parts that could be potentially dangerous to their users.So researchers have been working on building soft robots for decades. They’ve taken inspiration from nature, looking to animals from jellyfish to cockroaches, which are often made up of more flexible matter.But creating a completely soft robot remains a challenge. Even if engineers build a silicone(硅酮) body, it’s still a grand challenge to construct flexible versions of essential parts,such as a source of power.“Although soft robotics is still in its early stage, it holds great promise for several applications, such as search-rescue operations and exploration,” Barbara Mazzolai and Virgilio Mattoli of the Italian Institute of Technology Center for Micro-BioRobotics, wrote in a comment. “Soft robots might also open up new approaches to improving wellness and quality of life.”5. What’s the special feature of “Octobot”?A. It’s very small.B. It’s made of metal.C. It’s soft.D. It looks like an octopus.6. What’s the shortcoming of traditional robots?A. They’re hard to control.B. They can’t behave well all the time.C. They can’t predict conditions.D. They’re too heavy to move.7. Which of the following is wrong?A. The original robots can work on rough land well.B. The original robots may hurt people.C. It’s tough to invent an absolutely soft robot.D. The soft robots might improve the quality of human life.8. One of the biggest challenges is to build Octobot’s ________.A. silicone bodyB. complex structureC. precise movementsD. flexible power source二、七选五A Pen That Draws in Any ColorThe Scribble is a magical pen that can scan colors and instantly reproduce the colors. Hold the Scribble’s scanner up to any color, and within a second that color is stored in its memory. 9 Who can use the Scribble?Children will love the Scribble because it can create different colors, replacing even their biggest box of crayons. Besides, anyone working with color in their professional lives, such as artists, will be able to scan and reproduce colors instantly.10Green! One of the most important characteristics of the Scribble is that, since it can reproduce any color, it replaces marking pens, greatly reducing the huge amount of plastic waste.What’s inside the Scribble?There will be two different versions of the Scribble, the Scribble K and the Scribble S. The K will be able to reproduce exact colors on paper. It includes a color sensor and a rechargeable battery. 11 The S looks exactly the same as the K, but it is intended for use on screen.How did we create the Scribble?We’ve been in the design process for two years and the Scribble has gone through various design changes to get it to where we are now. Because of its small size we have created some ideas never seen before in the color reproduction industry. 12Thank you for your support.13 Thank you also for your support! Make sure to bookmark our website and check back often to see the progress as well as the updated times for production and delivery of your Scribble.A. What do we need the Scribble for?B. What’s the Scribble’s best colour?C. It’s the best birthday gift you may choose for your kids.D. Thank you so much for your concern about the Scribble.E. There is 1 GB of internal memory that will store over 100,000 colors.F. We created the Scribble for YOU and want you to be a part of the process.G. Once stored, that color can be used to draw on paper or on a digital screen.三、完形填空Wheeling her red chair and scissors around the city, Katie gives out-of-luck strangers the gift of visibility.Last summer, Katie saw a man sitting with a 14 asking for help. She asked, “Hey! I’m giving 15 haircuts. Do you want one?”The man, named Edward, was in his 60s. “ 16 ,” he said, “I have a funeral to go. I was really 17 to get a haircut.” After Katie was done, Edward looked in a mirror. “I look 18 !”“It’s more than a haircut. I want it to 19 value and respect.” Katie knows that a haircut can 20 a life. As a teen, she 21 a disease that was so severe that her hair thinned seriously. Seeing this, her mother 22 for Katie’s first haircut. “To sit down and have somebody look at me and talk to me like a person and not just an illness helped me feel cared about and less 23 .” she says.Katie wanted to help people 24 the same way. In 2009, she began her Red ChairProject, reaching out to people on the streets. Katie listens to peopled stories of loss, addiction, and 25 to get back on their feet. The attention 26 works.It all began with a belief in simple acts of 27 , such as a free haircut. “The way you show up in the world 28 ,” says Katie. “You have no idea what people will do with the kindness that you give them.”14.

Secondly, it is valuable for medical research on animals. Cloning plants is straightforward 31 cloning animals is very complicated. The procedure is difficult to undertake and at first it was not accurate enough. Many attempts to clone mammals 32 (fail). At last the determination and patience of the scientists paid 33 in 1996, with a breakthrough —the cloning of Dolly the sheep. Then came the 34 (disturb) news that Dolly was ill. Cloning scientists were cast down to find that Dolly’s illness was more appropriate to a much 35 (old) animal. Altogether Dolly lived for six and a half years, hal f the length of the life of the original sheep. Dolly’s appearance raised a storm of 36 (object) and had a great impact on the media and public imagination. It aroused an argument over whether 37 was moral to clone human beings.At present some countries began to reform their legal systems and forbade research into human cloning, but other countries like China and the UK, continued to accumulate evidence of the abundant medical aid that cloning could provide. Therefore, scientists still wonder whether cloning will help or harms and 38 it is leading us.五、应用文写作假设你是李华,计划今年考试后去英国旅行三周。

But now as grown-ups, some adults find they cannot leave childhood behind. They become "kidults" (kid+adult). Being a kidult has become a lifestyle-choice among young people across Asia.Some kidults collect toys they once played with. Hello Kitty, Garfield, and Snoopy have many adult fans around the world. It is not unusual to see a 20-something woman with a big, Garfield-shaped cushion on her sofa or a Hello Kitty mobile phone accessory.Other kidults still enjoy children's stories and fairy tales. For example, Bloomsbury even published the Harry Potter novels with an adult cover. That way, no one else on the subway will know that an adult is actually reading a children's book!"Kidults can be like vitamins to society. Adults who value their childhood and hold on to pure, child-like emotion may be needed in such a rough and dry society," said Lee Sojung, professor of Foreign Studies at Hankuk University(韩国外国语大学). He added that kidult culture may fill the generation gap between adults and kids. It could give children and their parents books, movies, and cartoon shows to enjoy together. He may be right.Tim Greenhalgh,a professor,explained that some kidults just refuse to grow up. They value childhood because life in a busy and stressful city frightens them. Kidults would like to forget their age and openly show their fear of society and adulthood.56. We can infer from the article that _________.A. Kidults miss their childhood so much that they can't give up their toysB. Bloomsbury knows some kidults don't want people to know that they are kidultsC. Kidults like to have vitamins very muchD. Some toys are so interesting that even adults like them very much57. According to the author, being a kidult is good in some way except that _______.A. it can improve the relationship between parents and their kidsB. it can help kidults feel relaxedC. it is helpful to solve some social problemsD. it can make people loyal to one's parents58. According to the writer, _______.A. being a kidult is nothing wrongB. kidults have mental problemsC. our society is very dullD. some people can never grow upBIf women are mercilessly exploited(剥削) year after year, they have only themselves to blame. Because they tremble at the thought of being seen in public in clothes that are out of fashion, they are always taken advantage of by the designers and the big stores. Clothes which have been worn only a few times have to be put asidebecause of the change of fashion.Changing fashions are nothing more than the intentional creation of waste. Many women spend large sums of money each year to replace clothes that have hardly been worn. Women who cannot afford to throw away clothing in this way, waste hours of their time changing their old-fashioned dresses. Skirts are lengthened or shortened; neck-lines are lowered or raised, and so on.No one can claim that the fashion industry contributes anything really important to society. Fashion designers are rarely concerned with necessary things like warmth, comfort and durability (耐用). They are only interested in outward appearance and they take advantage of the fact that women will put up with any amount of discomfort, as long as they look right. There can hardly be a man who hasn't at some time in his life smiled at the sight of a woman shaking in a thin dress on a winter day, or picking her way through deep snow in high heeled shoes.When comparing men and women in the matter of fashion, the conclusions to be drawn are obvious. Do the constantly changing fashions of women's clothes, one wonders, reflect basic qualities of inconstancy and instability? Men are too clever to let themselves be cheated by fashion designers. Do their unchanging styles of dress reflect basic qualities of stability and reliability(稳定耐用)? That is for you to decide.59. Designers and big stores always make money_________.A. by mercilessly exploiting women workers in the clothing industryB. because they are capable of predicting new fashionsC. by constantly changing the fashions in women's clothingD. because they attach great importance to quality in women's clothing60. To the writer, the fact that women change their old-fashioned dresses is seen as ___________.A. a waste of moneyB. a waste of timeC. an expression of tasteD. an expression of creativity61. New fashions in clothing are created for ___________.A. the commercial exploitation of womenB. the women's strength of characterC. basic qualities of inconstancy and instabilityD. an important contribution to society62. By saying "the conclusions to be drawn are obvious" ( Line One to Line Two, Paragraph Four), the writer means that ___________.A. women's inconstancy in their choice of clothing is often laughed atB. women are better able to put up with discomfortC. men are also exploited greatly by fashion designersD. men are more reasonable in the matter of fashionCWhile football fans feel strongly angry and shocked about mistakes made by referees (裁判) because they cannot see clearly what has happened, a small German company is quietly pleased.For Cairos Technologies, mistakes made by referees are the kind of advertising that money cannot buy. The company has developed a tiny chip(芯片) that fits inside a football and determines whether the ball has crossed the goal line, by being able to discover its exact location on the field. The world football organization, FIFA, has shown interest in the technology. It is very possible that the new technology will be used in the 2006 World Cup in Germany."We've been testing the technology at the main soccer stadium in Nuremberg for some time and more recently in an under-17 FIFA Cup in Peru," said Gunter Rohmer, a director of the company. "The technology has performed well, and we're pretty optimistic that it will be used at the games in Germany next year."The chip only weighs 12 grams, and is placed in the center of the football. It sends 2,000 signals a second to a receiver network of 12 antennas(天线),placed around the field. The receivers then send information about the ball's location to a central computer, and because it works in real time, it can immediately tell the referee whether a goal has been scored. The chip even can tell when the ball crosses the line in mid-air. Oliver Braun, one of the inventors of the chip, says that feedback from German referees was generally positive. Germany sports-wear giant Adidas is also optimistic about using this kind of chip in other ball sports.FIFA aims to test the technology later this year at another game in Japan before deciding whether or not to introduce it in all 12 stadiums in Germany for next year's World Cup.63. Carlos Technologies is pleased because ________.A. football fans are angry with refereesB. their new product can satisfy football fansC. their new product will have a good marketD. they can sell a lot of football in the future64. In the first sentence in Paragraph 2,"... mistakes made by referees are the kind of advertising that money cannot buy" means ___________.A. Carlos Technologies can't afford the high price for advertising their productB. Mistakes in production are also a kind of advertisementC. Carios Technologies has already spent a lot of money on advertising their productD. Referees' mistakes will be of great help for the sale of Carlos Technologies' new product65. The underlined word "feedback" probably means ___________.A. information given back by a userB. advice given by someoneC. supplying food to customersD. food given back by consumers66. The new product has drawn attention from some _________.A. famous peopleB. refereesC. big companiesD. countriesDLondon--A morning train rides away, across the channel. English kids discuss the Liverpool's football team in a Paris pub.Some Parisians have started to travel to work in London.In the 19th century, Charles Dickens compared the two cities, London and Paris, in A Tale of Two Cities. These days, it might be A tale of One City.As there are few jobs at home over recent years, perhaps 250,000 Frenchmen moved across the channel. With an undersea tunnel, they could travel between cities in three hours. The European Union freed them from immigration and customs. Paris, rich in beauty, is more stylish. But London feels more full of life, and more fun until the pubs shut down."For me, the difference is that London is real, alive," said Trevor Wheeler, a financial expert.Chantal Jaouen, a professional designer, agrees. "I am French, but I'll stay in London,'' she said.There is, of course, the other view. Julie Lenoux is a student who moved to London two years ago. "I think people laugh more in Paris," she said."Both cities have changed beyond recognition," said Larry Collins, an author and sometimes a Londoner.Like most people who know both cities well, he finds the two now fit together comfortably."I first fell in love with Paris in the 1950s. Things are so much more ordered, and life is better."But certainly not cheaper.In some parts of London, rents can be twice those on Avenue Foch in Paris. Deciding between London and Paris requires a lifestyle choice.Like Daphne Benoit, a French journalism student with perfect English, many young people are happy to be close enough so they don't have to choose."I love Paris, my little neighbourhood, the way I can walk around a centre, but life is too organized , "she said. "In London, you can be whoever you want. No one cares."67. It can be inferred that ___________.A. Paris and London are the two biggest cities in the worldB. in the 19th century, Dickens told his stories in the two citiesC. London and Paris used to be separatedD. Liverpool is a big city in France68. According to this passage, which of the following is TRUE?A. People feel it difficult to find a job in Paris.B. People can't travel to London without a passport.C. People can travel to London without a passport.D. People can find any job in London.69. According to this passage we know that _________.A. Parisians enjoy English food more than their ownB. Londoners seldom travel to Paris on holidaysC. both cities have their advantagesD. young people prefer to live in London70. Which city is better to live in according to the passage?A. Paris.B. London.C. Both cities.D. It just depends.71. What's the meaning of the last sentence?A. People can do everything in London.B. People will feel lonely in London.C. People in London enjoy living in different ways.D. People in London enjoy a lawless life.ENow let's look ourselves as a species in relation to ecosystem balance.Modern scientists believe that humankind, like other animals, evolved(进化) through millions of years of changes and adaptations to the environment and that our most direct evolutionary ancestor was probably an earlier species of the primate(monkey, ape) group. Despite this similarity with other creatures, however, the evolution of humankind differs from that of other species in one important and unique way. In other species, evolution has led to specialization, both in the species abilities and in its place within the environmental structure. For example, the giraffe is much adapted to feeding on treetops, but it is also specialized and thus limited to feeding on trees and shrubs. Only with great difficulty can it bend down to graze on the ground. Similarly, the anteater is extremely well adapted to eating ants but is unable to catch or eat other animals. The same is true for countless other species. For humankind it is opposite. Our evolution had led to a very generalized ability. Our highly developed intelligence and ability to make and handle tools mean that we can do almost anything. Humans evolved in such a way that we are able to move into every environment on Earth and even into space. No natural competitor offers great resistance, and other natural enemies such as disease have been controlled. Said another way, we see in humankind a great imbalance between biological potential and environmental resistance. The result is the rapidly increasing world population, frequently referred to as the population explosion. Further, to support our growing population, natural ecosystems are being increasingly displaced by human habitations, agriculture, and other human supporting activities.72. From the passage we can infer that in the course of evolution _________.A. humankind is very important to earlier species, such as the primate groupB. human beings are limited by the environment while animals are notC. human beings become more and more different from each otherD. humankind has experienced a generalization rather than specialization in ability73. According to the passage, primate includes such animals as ________.A. monkeys and anteatersB. tigers and apesC. apes and monkeysD. monkeys and giraffes74. According to the passage, evolution has made it possible for humans to _______.A. increase the populationB. resist natural offersC. go to the moonD. cure all diseases75. According to the author, imbalance between biological potential and environ mental resistance has resulted in ________.A. the population explosionB. the destruction of human habitationsC. the growth of natural ecosystemD. the specialization of humansIV 短文改错此题要求改正所给短文中的错误。
