1、考研英语(阅读)模拟试卷 11 及答案与解析Part ADirections: Read the following four texts. Answer the questions below each text by choosing A, B, C or D. (40 points)0 The Relationship Between Dinesaurs and BirdsThe once radical notion that birds descended from dinosaursor may even be dinosaurs, the only living branch o
2、f the family that ruled the earth eons agohas got stronger and stronger since paleontologists first started taking it seriously a couple of decades ago. Remarkable similarities in bone structure between dines and birds were the first clue. Then came evidence, thanks to a series of astonishing discov
3、eries in Chinas Liaoning province over the past five years, that some dinosaurs may have borne feathers. But a few scientists still argued that the link was weak; the bone similarities could be a coincidence, they said. And maybe those primitive structures visible in some fossils were feathers, but
4、maybe not. You had to use your imagination to see them.Not anymore. A spectacularly preserved fossil of a juvenile dinosaur announced by a team of paleontologists from the Chinese Academy of Geological Sciences and New York Citys American Museum of Natural History in the latest issue of Nature, is a
5、bout as good a missing link as anyone could want.“It has things that are undeniably feathers,“ exults Richard Prum, of the University of Kansas Natural History Museum, an expert on the evolution of feathers. “But it is clearly a small, vicious theropod similar to the velo-ciraptors that chased the k
6、ids around the kitchen in Jurassic Park.“The find helps cement the dinosaur-bird connection, but it also casts new light on the mystery of why nature invented feathers in the first place. For the better part of a century, biologists have assumed that these specialized structures evolved for flight,
7、but thats clearly not true. “The feathers on these dinosaurs arent flight-worthy, and the animals couldnt fly,“ says paleontologist Kevin Padian, of the University of California, Berkeley. “Theyre too big, and they dont have wings.“ So what was the original purpose of feathers? Nobody knows for sure
8、; they might have been useful for keeping dines dry. distracting predators or attracting mates, as peacocks do today.But many biologists suspect that feathers originally arose to keep dinosaurs warm. The bone structure of dinosaurs shows that, unlike modem reptiles, they grew as fast as birds and ma
9、mmalswhich dovetails with a growing body of evidence that dines were, in fact, warm-blooded. Says Padian: “They must have had a high basal metabolic rate to grow that fast. And I wouldnt be surprised if they had some sort of skin covering for insulation when they were small.“ Says Norell. “Even baby
10、 tyrannosaurs probably looked like this one.“At the rate feathered dinosaurs are turning up, it shouldnt take long to solidify scientists understanding of precisely how and why feathers first arose and when the first birdlike creature realized they were useful for flight. Meanwhile, kids had better

13、) it further proves the link between birds and dinosaurs(D)it solves the puzzle of birds evolution3 In the view of Kevin Padian, the feathers on those dinosaurs_.(A)were of no practical value(B) were useful for flight(C) could protect dinosaurs from their natural enemy(D)were good for insulation4 Th

15、und in certain parts of the world(D)scientists understand precisely how and why feathers first arose5 The Online Autocar Rents TrafficWhen eBay, now the worlds biggest auction website, went online in 1995, many expected it to fail. Why would anyone buy used items from perfect strangers? Two new serv
16、ices WhipCar, which was launched in London on April 21st, and RelayRides, which will start up in Boston, Massachusetts, early this summer will face similar skepticism. Both aim to get car-owners to rent their vehicles to strangers when not using them themselves.At heart, both offerings are online ex
17、changes. Car-owners and drivers register, contact one another through the site and agree to a rental contract. To ensure that both parties are trustworthy, WhipCar asks, among other things, for details of both the rented cars registration and the renters license, and checks them against official dat
18、a. It also provides insurance for the duration of the rental and a replacement car if there is an accident. In addition to these measures, RelayRides only accepts cars that have gone through a safety check and installs a device that allows them to be unlocked with a special card. This way, owners an
19、d renters do not have to meet, as they do with WhipCar.Both firms allow owners to set the price, taking a 15% cut. Even with the insurance premium and other fees added in, the firms expect the rental price to be lower than using a conventional car-rental firm or an urban car-sharing club. WhipCar pr
20、ovides suggestions for the prices different cars might fetch in various neighborhoods. Shortly after the site went live an Audi A4 in central London cost 10 ($ 15) an hour or 41 a day.Will the idea take off? The main hurdle will be car-owners reluctance to share so personal a possession and the requ
21、irement to keep it clean. The firms must also overcome a problem all exchanges face: attracting enough members to make the service useful.Yet cars are expensive, underused assets. On average, a British car is driven for less than an hour a day but costs about 5, 500 a year to owna sum many would lov

By 2016 some 4. 4 million Americans will he members of a car-sharing club, nearly ten times as many as today, projects Frost some parents are worried that it hurts high-achieving students chances of
