That’s an interesting choice of adjective, coming from a man who has spent millions of dollars trying to clone a 13-year-old dog named Missy. So far, he and his team have not succeeded, though they have cloned two cows and a cat.
They just might succeed in cloning Missy soon — or perhaps not for another five years.
Westhusin"s experience with cloning animals leaves him upset by all this talk of human cloning. In three years of work on the Missy project, using hundreds upon hundreds of dog"s eggs, the A&M team has produced only a dozen or so embryos carrying Missy"s DNA. None have survived the transfer to a surrogate（代孕的）mother. The wastage of eggs and the many spontaneously aborted(流产，发育不全) fetuses（胎）may be acceptable when you"re dealing with cats or bulls, he argues, but not with humans. “Cloning is incredibly inefficient, and also dangerous,” he says.
Even so, dog cloning is a commercial opportunity, with a nice research payoff. Ever since Dolly the sheep was cloned in 1996, Westhusin"s phone has been ringing with people calling in hopes of duplicating their cats and dogs, cattle and horses. “A lot of people want to clone pets, especially if the price is right,” says Westhusin. Cost is no obstacle for Missy"s mysterious billionaire owner; he"s put up $3.7 million so far to fund A&M"s research.
Contrary to some media reports, Missy is not dead. The owner wants a twin to carry on Missy"s fine qualities after she does die. The prototype（原型；雏形）is, by all accounts, athletic, good-natured and super-smart. Missy"s master does not expect an exact copy of her. He knows her clone may not have her temperament（气质、性情）. In a statement of purpose, Missy"s owner and the A&M team say they are “both looking forward to studying the ways that her clones differ from Missy.”
Besides cloning a great dog, the project may contribute insight into the old question of nature vs. nurture. It could also lead to the cloning of special rescue dogs and many endangered animals.
However, Westhusin is cautious about his work. He knows that even if he gets a dog pregnant, the offspring, should they survive, will face the problems shown at birth by other cloned animals: abnormalities like immature lungs and heart and weight problems~ “Why would you ever want to clone humans,” Westhusin asks, “when we"re not even close to getting it worked out in animals yet?”
小题1:By “stupid endeavor”, Westhusin means to say that ________.
| A．human cloning is a foolish undertaking |
| B．animal cloning is absolutely impractical |
| C．human cloning should be done selectively |
| D．animal cloning is not worth the effort at all |
| A．Its success is already in sight. |
| B．It is progressing smoothly. |
| C．It is doomed to utter failure. |
| D．Its outcome remains uncertain. |
| A．study the possibility of cloning humans |
| B．search for ways to modify its temperament |
| C．find out the differences between Missy and its clones |
| D．examine the reproductive system of the dog species |
| A．a bad temper |
| B．defective（有缺陷的、有毛病的）organs |
| C．immune deficiency |
| D．an abnormal shape |
| A．Cloning of Missy |
| B．Scientist Says ‘No’ to Human Cloning |
| C．Human Cloning Is Dangerous . |
| D．Westhusin Is Cautious about Cloning |
答案
小题1:A
小题2:D
小题3:C
小题4:B
小题5:B
解析
试题分析：文章介绍了关于克隆方面的知识，由此让读者认识到克隆人类不是明智的选择。
小题1:猜测词义题。根据第一句“I’ve never met a human worth cloning,可知是指克隆人是一个愚蠢的做法。所以选A。
小题2:推理题。根据文章第二段可知这个计划的结果还是不确定的，它提及这个，是想告诉人们克隆人会有很多的困难与问题。所以选D。
小题3:细节题。根据文章倒数第三段最后一句“both looking forward to studying the ways that her clones differ from Missy.”可知Mark Westhusin 通过克隆Missy发现Missy和她克隆的不同,所以选C。
小题4:推理题。根据文章第4段内容可知动物克隆会产生很多有缺陷的胚胎和器官，很不成功。所以选B。
小题5:标题确定题：根据文章内容和第一段的句子：“I’ve never met a human worth cloning,” says cloning expert Mark Westhusin from his lab at Texas A&M University. “It’s a stupid endeavor.”可知这篇文章主要介绍科学家不同意克隆人类，所以选B。

| LONDON, England (CNN)—The youngest person to sail solo around the world returned home Thursday from his 30,000-mile, 282-day ocean journey. Mike Perham, 17, sailed into Lizard Point in Cornwall, the southernmost point in Britain, at 9:47 a.m., his race team said. "It feels absolutely brilliant," Mike told CNN by phone hours before crossing the finish line. "I"m really, really excited to be going across the line at last. It doesn"t feel like long since I crossed it first." Mike set off on his round-the-world trip on November 18, 2008. He has been sailing his yacht single-handedly, though a support team has been sailing next to him along the way. The teen has now achieved the title of Youngest Sailor to Circumnavigate the Globe Solo, according to the Guinness World Records. Mike learned how to sail when he was seven years old from his father, Peter and at age 14, he sailed across the Atlantic alone. The teenager"s school-which Mike describes as"highly supportive" of his trip-has redesigned his coursework to fit in with his trip. It also gave him some coursework to do during"quiet moments," according to Mike"s Web site. There haven"t been many of those quiet moments. Repeated autopilot failures forced him to stop for repairs in Portugal, the Canary Islands, South Africa, and twice in Australia, according to his Web site. Bad weather in the Southern Ocean-between Australia and Antarctica-forced Mike to battle 50ft waves and 57 mph winds. He said at one point, a "freak wave" picked up the boat and turned it on its side. "My feet were on the ceiling at the time," he told CNN. "That was a really hairy moment, and I was certainly thinking, "Why am I here?" But we took the sails off and the day after I thought, "This is brilliant!"" Mike describes his father as his biggest hero, always supportive of what he wanted to achieve. Peter Perham said he wasn"t too worried about his son facing dangerous situations at sea, as long as he knew what to do and stayed safe. | |

| COPENHAGEN-The world is gathered in Copenhagen for the U.N. climate summit, but Denmark"s bicycle-friendly capital has also given its name to a movement of cities trying to find a kinder way to commute (往返上下班). Nearly 40 percent of Copenhagen"s population cycle to work or school on ubiquitous (无处不在的) paved cycle paths. Many residents take to their bikes year-round, braving rain and snow through the winter in a city where the bicycles outnumber the people. Amsterdam and Beijing too are known for their bicycles, but the Danish capital is where urban planners from around the world have been looking for ways to get their people out of cars and up onto bikes, an effort known as Copenhagenisation. Klaus Bondam, Copenhagen"s technical and environmental chief, calls himself a "mega cyclist" and says the bike"s popularity stems partly from high taxes on cars which meant working-class Danes could not afford to drive in the 1930s and 40s. "Today you"ll meet everybody on the bicycle lanes-women and men, rich and poor, old and young," Bondam said. The local government has during the last three years invested more than 250 million crowns ($49.42 million) in bicycle lanes and to make the traffic safer for bicyclists. Today around a third of the population drive cars to work or study, another third take public transport, while 37 percent cycle-a figure the city aims to boost to 50 percent by 2015. There are many benefits when citizens choose bicycles over cars: pollution and noise decline, public health improves, and more people on bikes or walking creates a sense of safety in the city. Fewer parked cars leaves more space for playgrounds, parks, shopping areas and other useful public places. | |
| 1. According to the first paragraph, Copenhagen is better known as ______. | |
| [ ] | |
| A. a city without cars B. a bicycle-friendly city C. Denmark"s capital D. the U.N. climate summit | |
| 2. We can learn from the second and the third paragraph, ______. | |
| [ ] | |
| A. there is no path for cars during rainy and snowy days B. citizens are limited to have only one bike for each person C. two-thirds of people in Copenhagen cycle to work or school D. city planners try their best to encourage more citizens to ride bikes | |
| 3. Bikes are popular in Copenhagen partly because ______. | |
| [ ] | |
| A. the citizens are unable to afford to buy a car B. the rich tend to keep fit by cycling to work C. young people regard cycling a fashion to follow D. high taxes were paid for cars in the 1930s and 40s | |
| 4. Which of the following is NOT the benefit of cycling? | |
| [ ] | |
| A. Saving time on the road. B. Declining pollution and noise. C. Improving public health. D. Creating safety in the city. | |
