In this film, scientists use DNA kept for tens of millions of years to clone dinosaurs. They find trouble, however, when they realize that the cloned creatures are smarter and more dangerous than expected. Thats nothing more than a fiction.But could we really clone endangered animals?To date, the most successful attempt to do so was the cloning of a gaur, a rare oxlike animal from southeast Asia. Scientists used a cow to bring the cloned baby gaur, named Noah. Two days after birth, however, Noah died from a common bacterial infection. Other endangered species that may be cloned include the African bongo antelope (羚羊), the Sumatran tiger, the cheetah (猎豹), and the giant panda.Next, could we really clone extinct animals?In theory? Yes. To do this, you need a wellkept source of DNA from the extinct animals such as wool mammoth (毛象), Tasmanian tiger, or even dinosaur, and a closely related species, still living, which could serve as a_surrogate_mother.In reality? Probably not. On the one hand, its not likely that extinct animals DNA could survive undamaged for such a long time. Cloning such extinct animals as wool mammoth, Tasmanian tiger, or dinosaur is much more difficult due to the lack of properly wellpreserved DNA. On the other hand, for example, a gaur can have a cow as a surrogate mother, definitely not a monkey. But what about an extinct animal as unique as the panda? What species could possibly serve as a surrogate mother?Cloning presents many exciting possibilities. However, even if extinct animals were brought back, they could not survive in todays world. Not only do most extinct animals have no habitat to live in, but the other plants and animals they depended on for food may also be gone as well.语篇解读：本文说明了在克隆灭绝动物的过程中遇到的重重困难与障碍。即使克隆成功了，其赖以生存的食物链也已经被破坏，被克隆出来的动物也无法继续生存下去。1It can be learned from the text that _.Athe gaur is an extinct speciesBthe gaur lives in Asia and is endangeredCscientists have cloned the African bongo antelopeDboth the cheetah and the giant panda live in Asia解析：选B细节理解题。根据第二、三段可知，印度野牛生活在亚洲的东南部，濒临灭绝。2The underlined words “a surrogate mother” probably refer to a female who _.Agives birth to a baby of its ownBcannot give birth to a babyCgives birth to a baby for another femaleDprovides DNA解析：选C词义猜测题。根据第五段的描述可知，此处表示的是，把一种动物的DNA提取出来之后，在另外一种动物的体内进行胚胎繁殖，而这种动物就被称为a surrogate mother，由此判断，画线部分意思为“代孕妈妈”，故C项正确。3The difficulty in cloning an extinct species is the lack of _.Aboth the wellpreserved DNA and a surrogate motherBboth the habitat to live in and the wellpreserved DNACboth the wellpreserved DNA and plants to live onDboth the habitat to live in and plants to live on解析：选A细节理解题。根据文章倒数第二段中的“On the one hand . On the other hand .”两个方面的表述可知，克隆的困难在于一是要寻找灭绝动物的保存完好的DNA，二是要寻找到合适的代孕的物种，故A项正确。4In the authors opinion, it is possible that _.Aall the extinct species may be clonedBextinct species may be cloned and easily surviveCa gaur can have a monkey as a surrogate motherDsome extinct species may be cloned, but not survive解析：选D细节理解题。本文作者客观叙述了在克隆灭绝动物过程中所存在的种种困难与障碍。根据最后一段的表述可知，也许克隆存在众多的可能性，但是即使克隆成功了，也许会由于其赖以生存的食物链已经灭绝而无法继续存活下去。由此判断D项正确。BWorlds of FunLocation: Worlds of Fun is located off Highway 435 in Kansas City, Missouri.History: Worlds of Fun was opened on May 26, 1973, at a cost of 25 million dollars. Loosely themed around the Jules Verne book, Around the World in Eighty Days, the park was founded by Hunt Midwest Company. In 1982, Hunt Midwest bought a nearby waterpark, Oceans of Fun. In 2013, Worlds of Fun and Oceans of Fun were combined to a one ticket admission, providing all guests with access to 235 acres of amusement and water rides. Hours: Worlds of Fun is open from April through Halloween. Tickets: Buy and print online. Always try to buy your tickets in advance, to save time when you get to the park. Reservations: Worlds of Fun sells “Fast Lane” cards that save riders time by allowing them to bypass the majority of wait for most of rides and attractions including Mamba, Prowler, and Patriot. Ride as many times as you want all day long. Strategy: Most visitors tend to begin the day with Prowler, the hottest attraction in the park. Use that tendency to your advantage and head to the Patriot first. After that, try the Dragons. Then work your way back to the Prowler. After riding the Prowler, there is only one coaster left, Mamba. Hit it next. If the park is not very crowded, you can ride Boomerang on the way to Mamba. After riding Mamba, head back for a ride on the Wolf. By then you will have tried most of the popular rides and attractions in the shortest possible time. News: In 2017, Worlds of Fun is adding Steel Hawk, a ride that will take guests up 301 feet in the air and spin them at a 45degree angle for a 60second flight. Wait to have a try! 语篇解读：本文是一篇应用文。文章主要向我们介绍了娱乐公园“欢乐世界”的一些情况：位置、历史、开放时间、门票、预定时间及旅游攻略等信息。5When did Hunt Midwests two parks start to share one ticket?AIn 1973BIn 2013CIn 1982 DIn 2014解析：选B细节理解题。根据第二段最后一句可知选B。6With a “Fast Lane” card, the visitor can _.Asave some moneyBbuy tickets onlineCavoid lining up for longDenjoy all the rides for free解析：选C细节理解题。根据第五段可知，“Fast lane” card是一种快车道卡，它可以减少游客在大多数骑乘项目和包括Mamba, Prowler, Patriot在内的景点的等待时间。故C项正确。7What is talked about in the part of Strategy?AThe hottest attractions in the park.BThe highest ride in the park.CThe most popular tour season.DThe best visiting route.解析：选D推理判断题。根据Strategy部分出现的一些时间过渡词，可知作者想说的是旅游线路。8According to the passage, by beginning with_ a visitor can try most of the popular rides and attractions in the shortest possible time.AProwler BDragonsCPatriot DWolf解析：选C细节理解题。根据倒数第二段中第二句和最后一句可知选C。能在最短的时间内参观最多的名胜和坐完最受欢迎的骑乘时要先从Patriot处开始参观。CReading can be a social activity. Think of the people who belong to book groups. They choose books to read and then meet to discuss them. Now, the website BookC turns the page on the traditional idea of a book group.Members go on the site and register the books they own and would like to share. BookCrossing provides an identification number to stick inside the book. Then the person leaves it in a public place, hoping that the book will have an adventure, traveling far and wide with each new reader who finds it.Bruce Pederson, the managing director of BookCrossing, says, “The two things that change your life are the people you meet and books you read. BookCrossing combines both.”Members leave books on park benches and buses, in train stations and coffee shops. Whoever finds their book will go to the site and record where they found it.People who find a book can also leave a journal entry describing what they thought of it. Emails are then sent to the BookCrossers to keep them updated about where their books have been found. Bruce Pederson says the idea is for people not to be selfish by keeping a book to gather dust on a shelf at home.BookCrossing is part of a trend among people who want to get back to the “real” and not the virtual (虚拟). The site now has more than one million members in more than one hundred thirtyfive countries.语篇解读：本文属于说明文，介绍了BookC所进行的分享图书活动的目的以及具体过程。9Why does the author mention book groups in the first paragraph?ATo explain what they are.BTo introduce BookCrossing.CTo stress the importance of reading.DTo encourage readers to share their ideas.解析：选B写作意图题。作者在第一段中提出读书也是一种社交活动，那些参加读书小组的人经常在一起阅读讨论所读内容，增强相互之间的理解。接着在最后一句提出BookC，说明作者提到读书小组的目的正是为了介绍网站BookC。故B正确。 10What does the underlined word “it” in Paragraph 2 refer to?AThe book.BAn adventure.CA public place.DThe identification number.解析：选A代词指代题。根据本句“. hoping that the book will have an adventure, traveling far and wide with each new reader who finds it.”可知，那些留下书的人希望自己的书能够随着找到它的人走得更远。可知其中it指代前半句提到的同一事物“the book”。故A正确。11What will a BookCrosser do with a book after reading it?AMeet other readers to discuss it.BKeep it safe in his bookcase.CPass it on to another reader.DMail it back to its owner.解析：选C推理判断题。根据文章第五段最后一句“. the idea is for people not to be selfish by keeping a book to gather dust on a shelf at home.”可知，让书蒙上尘土是一种很自私的行为，网站BookC的目的正是鼓励人们与别人分享图书，所以拿到书的人最可能继续把书传递下去。故C项正确。12What is the best title for the text?AOnline Reading: A Virtual TourBElectronic Books: A new TrendCA Book Group Brings Tradition BackDA Website Links People through Books解析：选D标题归纳题。根据文章第三段可知BookC把改变人生的两种事物：遇到的人和读过的书联系在一起。D项内容能够涵盖文章的中心思想。DWhen I was 12, I got a parttime job on a dairy farm, milking cows. We milked 65 cows twice a day. One day, I complained to my father about having to go milk those cows, saying it was tiring. He said, you know, boy, to work is a blessing. I looked at the men whod worked harder. I had a feeling I had been told something really important, but it took many years before it sunk in.Back then, going to college was a rare privilege. My father told me if Id picked something to study that I liked doing, Id always look forward to my work. But he also added, even having a job you hate is better than not having a job at all. I wanted to be a farmer, but I joined a military program to help pay for college. And what started out as an obligation to the Army became a way of life that I stayed committed to for 37 years.In the late 1980s, during a visit to Bangladesh, I saw a woman with her baby on her back, breaking bricks with a hammer. I asked a local officer why they werent using a machine to make the work easier. He told me a machine would put that lady out of work. And as bad as that womans job was, it was enough to keep a small family alive. It reminded me of my fathers words: to work is a blessing.After seeing a lot of people like that woman in Bangladesh, Ive come to believe that people without jobs are not free. Theyre victims of crime, poor health, and depression. People who have jobs can have a home, send their kids to school, develop a sense of pride, contribute to the good of the community and even help others. When we can work, we are free. We are blessed.语篇解读：作者在本文中通过自己的亲身经历告诉我们有工作是一件很幸运的事情，因为有了工作我们就有了我们需要的一切。所以我们要珍惜自己的工作机会。13Which can be the best title of the text?AMy chosen way of lifeBTo work is a blessingCWhy should I workDInspiration from a woman解析：选B标题归纳题。在本文中作者详细描述了自己的人生道路中父亲的话的影响，作者多次提到“He said, you know, boy, to work is a blessing.”有工作是好事。有了工作才可以有一切。14The writer joined a military program because _.Ahis parents forced him to do soBhe intended to find a lifetime jobChe couldnt afford his college educationDhe could travel abroad with the army解析：选C细节理解题。根据文章第二段的“I wanted to be a farmer, but I joined a military program to help pay for college.”可知我参军主要是因为自己付不起大学的学费。15What does the writer intend to say through the last paragraph?APeople without jobs could achieve more.BFreedom is not always free for people.CRich people should help those in need.DWe should feel fortunate to have a job.解析：选D 段落大意题。根据文章最后一段的“People who have jobs can have a home .free.
