The failure of a high-profile cholesterol drug has thrown a spotlight on the complicated machinery that regulates cholesterol levels. But many researchers remain confident that drugs to boost levels of 'good' cholesterol are still one of the most promising means to combat spiralling heart disease.B：2. Drug company Pfizer announced on 2 December that it was cancelling all clinical trials of torcetrapib, a drug designed to raise heart-protective high-density lipoproteins (HDLs). In a trial of 15000 patients, a safety board found that more people died or suffered cardiovascular problems after taking the drug plus a cholesterol-lowering statin than those in a control group who took the statin alone.C：3. The news came as a kick in the teeth to many cardiologists because earlier tests in animals and people suggested it would lower rates of cardiovascular disease. "There have been no red flags to my knowledge," says John Chapman, a specialist in lipoproteins and atherosclerosis at the National Instit6.It could help rid human body of cholesterol.A：TorcetrapicB：HDLSC：StatinD：CETP7.Researchers are yet to find more about it.A：TorcetrapicB：HDLSC：StatinD：CETP8.It was used to reduce the level of cholesterol.A：TorcetrapicB：HDLSC：StatinD：CETP9.According to Kashyap, it might lead to unwanted result if its blocked.A：TorcetrapicB：HDLSC：StatinD：CETP10.It produced contradictory results in different trials.A：TorcetrapicB：HDLSC：StatinD：CETP11.It could inhibit LDLs.A：TorcetrapicB：HDLSC：StatinD：CETP12.Don't wash those fossils!Standard museum practice can wash away DN1. Washing, brushing and varnishing fossils all standard conservation treatments used by many fossil hunters and museum curators alike vastly reduces the chances of recovering ancient DN2. Instead, excavators should be handling at least some of their bounty with gloves, and freezing samples as they are found, dirt and all, concludes a paper in the Proceedings of the National Academy of Sciences today. 3. Although many palaeontologists know anecdotally that this is the best way to up the odds of extracting good DNA, Eva-Maria Geigl of the Jacques Monod Institute in Paris, France, and her colleagues have now shown just how important conservation practices can be. This information, they say, needs to be hammered home among the people who are actually out in the field digging up bones. 4. Geigl and her colleagues looked at 3,200-year-old fossil bones belonging to a single individual of an extinct cattle species, called an aurochs. The fossilA：Warm and wet13. Geigl herself believes that, with cooperation between bench and field researchers, preserving fossils properly could open up avenues of discovery that have long been assumed closed. 14. Much human cultural development took place in temperate regions. DNA does not survive well in warm environments in the first place, and can vanish when fossils are washed and treated. For this reason, Geigl says, most ancient DNA studies have been done on permafrost samples, such as the woolly mammoth, or on remains sheltered from the elements in cold caves including cave bear and Neanderthal fossils. 15. Better conservation methods, and a focus on fresh fossils, could boost DNA extraction from more delicate specimens, says Geigl. And that could shed more light on the story of human evolution.Questions 8-12Do the following statements agree with the information given in the passage? Please writeTRUE if the statement agrees with the writerFALSE if the statement does not agree with the writerNOT13.Questions 13-14Complete the following the statements by choosing letter A-D for each answer.“This information” in paragraph 3 indicates:A：A It is critical to follow proper practices in preserving ancient DNB：B The best way of getting good DNA is to handle fossils with gloves.C：C Fossil hunters should wear home-made hammers while digging up bones.D：D Many palaeontologists know how one should do in treating fossils.14.The study conducted by Geigl and her colleagues suggests:A：A the fact that ancient DNA can not be recovered from fossil bones excavated in the past.B：B the correlation between the amount of burying time and that of the recovered DNC：C the pace at which DNA degrades.D：D the correlation between conservation practices and degradation of DN15.How shops can exploit people's herd mentality to increase salesA：1. A TRIP to the supermarket may not seem like an exercise in psychological warfarebut it is. Shopkeepers know that filling a store with the aroma of freshly baked bread makes people feel hungry and persuades them to buy more food than they had intended. Stocking the most expensive products at eye level makes them sell faster than cheaper but less visible competitors. Now researchers are investigating how “swarm intelligence” (that is, how ants, bees or any social animal, including humans, behave in a crowd) can be used to influence what people buy.B：2. At a recent conference on the simulation of adaptive behaviour in Rome, Zeeshan-ul-hassan Usmani, a computer scientist from the Florida Institute of Technology, described a new way to increase impulse buying using this phenomenon. Supermarkets already encourage shoppers to buy things they did not realise they wanted: for instance, by placing everyday items such as milk and eggs at the back of the store, forcing shoppers to walk past other tempting16.Rogue theory of smell gets a boostA：1. A controversial theory of how we smell, which claims that our fine sense of odour depends on quantum mechanics, has been given the thumbs up by a team of physicists.B：2. Calculations by researchers at University College London (UCL) show that the idea that we smell odour molecules by sensing their molecular vibrations makes sense in terms of the physics involved.C：3. That's still some way from proving that the theory, proposed in the mid-1990s by biophysicist Luca Turin, is correct. But it should make other scientists take the idea more seriously.D：4. "This is a big step forward," says Turin, who has now set up his own perfume company Flexitral in Virginia. He says that since he published his theory, "it has been ignored rather than criticized."E：5. Most scientists have assumed that our sense of smell depends on receptors in the nose detecting the shape of incoming molecules, which triggers a signal to the brain. This molecular 'lock and key' process is thought to lie behind a wide rang17.Its a waste of time_ with such a silly fellow.A：trying to reasonB：tried to reasonC：for trying to reasonD：to trying reasoning18.I wish you_ the play last night.Its a shame that I_A：had attended; didntB：attended; didntC：had attended; hadntD：could attend; havent19._ I have made no arrangements to deal with such cases.A：It appear thatB：That appearsC：They appear thatD：It appears that20.They are so alike that you cant tell_ is which.A：whatB：thatC：whichD：how21.Batteries must be kept in dry places_ electricity should leak away.A：whereB：lestC：thatD：unless22.I dont like_ you speak to her.A：the wayB：the way in thatC：the way whichD：the way of which23.Listening carefully to_ in class means less work later.A：what does the teacher sayB：what the teacher saysC：that the teacher saysD：which the teacher says24.She was trying to make a final statement, but people kept_ her speech by shouting.A：taking outB：putting offC：giving upD：getting along25.His success was due to_ he had been working hard.A：thatB：the fact whichC：the fact thatD：the fact that26.He spent as much time as he_ English.A：could learningB：learnedC：would learnD：had learned27.By the time he was twelve, Edison_ to make a living by him.A：would beginB：has begunC：had begunD：was begun28.How long_ each other before they_ married for about a year.A：have they known; getB：did they know; were going to getC：do they know; are going to getD：had they known; got29.He said a new bridge_ near this village the next year.A：builtB：had been builtC：was builtD：would be built30.I would appreciate_ back this afternoon.A：you to callB：you callC：your callingD：youre calling31.There are five pairs_, but Im at a loss which to buy.A：to be chosenB：to choose fromC：to chooseD：for choosing32.He prefers to stay here_ go home.A：than toB：rather thanC：rather than toD：than33.Id rather you_ smoking as soon as possible.A：quittingB：had quitC：quitD：to quit34.-Is this book_ you want to buy?-Yes.
