12月雅思考试真题 1
Selling Digital Music without Copy-protection Makes Sense
A.
It was uncharacteristically low-key for the industry’s greatest showman. But the essay published this week by Steve Jobs, the boss of Apple, on his firm’s website under the unassuming title “Thoughts on Music” has nonetheless provoked a vigorous debate about the future of digital music, which Apple dominates with its iPod music-player and iTunes music-store. At issue is “digital rights management” (DRM)—the technology guarding downloaded music against theft. Since there is no common standard for DRM, it also has the side-effect that songs purchased for one type of music-player may not work on another. Apple’s DRM system, called FairPlay, is the most widespread. So it came as a surprise when Mr. Jobs called for DRM for digital music to be abolished.
B.
This is a change of tack for Apple. It has come under fire from European regulators who claim that its refusal to license FairPlay to other firms has “locked in” customers. Since music from the iTunes store cannot be played on non-iPod music-players (at least not without a lot of fiddling), any iTunes buyer will be deterred from switching to a device made by a rival firm, such as Sony or Microsoft. When French lawmakers drafted a bill last year compelling Apple to open up FairPlay to rivals, the company warned of “state-sponsored piracy”. Only DRM, it implied, could keep the pirates at bay.
C.
This week Mr. Jobs gave another explanation for his former defence of DRM: the record companies made him do it. They would make their music available to the iTunes store only if Apple agreed to protect it using DRM. They can still withdraw their catalogues if the DRM system is compromised. Apple cannot license FairPlay to others, says Mr Jobs, because it would depend on them to produce security fixes promptly. All DRM does is restrict consumer choice and provide a barrier to entry, says Mr Jobs; without it there would be far more stores and players, and far more innovation. So, he suggests, why not do away with DRM and sell music unprotected? “This is clearly the best alternative for consumers,” he declares, “and Apple would embrace it in a heartbeat.”
D.
Why the sudden change of heart? Mr Jobs seems chiefly concerned with getting Europe’s regulators off his back. Rather than complaining to Apple about its use of DRM, he suggests, “those unhappy with the current situation should redirect their energies towards persuading the music companies to sell their music DRM-free.” Two and a half of the four big record companies, he helpfully points out, are European-owned. Mr Jobs also hopes to paint himself as a consumer champion. Apple resents accusations that it has become the Microsoft of digital music.
E.
Apple can afford to embrace open competition in music players and online stores. Consumers would gravitate to the best player and the best store, and at the moment that still means Apple’s. Mr Jobs is evidently unfazed by rivals to the iPod. Since only 3% of the music in a typical iTunes library is protected, most of it can already be used on other players today, he notes. (And even the protected tracks can be burned onto a CD and then re-ripped.) So Apple’s dominance evidently depends far more on branding and ease of use than DRM-related “lock in”.
F.
The music giants are trying DRM-free downloads. Lots of smaller labels already sell music that way. Having seen which way the wind is blowing, Mr Jobs now wants to be seen not as DRM’s defender, but as a consumer champion who helped in its downfall. Wouldn’t it lead to a surge in piracy? No, because most music is still sold unprotected on CDs, people wishing to steal music already can do so. Indeed, scrapping DRM would probably increase online-music sales by reducing confusion and incompatibility. With the leading online store, Apple would benefit most. Mr Jobs’s argument, in short, is transparently self-serving. It also happens to be right.

12月雅思考试真题 2
1. 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.
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.
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 Institute for Health and Medical Research (INSERM) in Paris who has also studied torcetrapib. This cancellation came as a complete shock.
4. Torcetrapib is one of the most advanced of a new breed of drugs designed to raise levels of HDLs， which ferry cholesterol out of artery-clogging plaques to the liver for removal from the body. Specifically， torcetrapib blocks a protein called cholesterol ester transfer protein (CETP)， which normally transfers the cholesterol from high-density lipoproteins to low density， plaque-promoting ones. Statins， in contrast， mainly work by lowering the ’bad’ low-density lipoproteins.
Under pressure
5. Researchers are now trying to work out why and how the drug backfired， something that will not become clear until the clinical details are released by Pfizer. One hint lies in evidence from earlier trials that it slightly raises blood pressure in some patients. It was thought that this mild problem would be offset by the heart benefits of the drug. But it is possible that it actually proved fatal in some patients who already suffered high blood pressure. If blood pressure is the explanation， it would actually be good news for drug developers because it suggests that the problems are specific to this compound. Other prototype drugs that are being developed to block CETP work in a slightly different way and might not suffer the same downfall.
6. But it is also possible that the whole idea of blocking CETP is flawed， says Moti Kashyap， who directs atherosclerosis research at the VA Medical Center in Long Beach， California. When HDLs excrete cholesterol in the liver， they actually rely on LDLs for part of this process. So inhibiting CETP， which prevents the transfer of cholesterol from HDL to LDL， might actually cause an abnormal and irreversible accumulation of cholesterol in the body. You’re blocking a physiologic mechanism to eliminate cholesterol and effectively constipating the pathway， says Kashyap.
Going up
7. Most researchers remain confident that elevating high density lipoproteins levels by one means or another is one of the best routes for helping heart disease patients. But HDLs are complex and not entirely understood. One approved drug， called niacin， is known to both raise HDL and reduce cardiovascular risk but also causes an unpleasant sensation of heat and tingling. Researchers are exploring whether they can bypass this side effect and whether niacin can lower disease risk more than statins alone. Scientists are also working on several other means to bump up high-density lipoproteins by， for example， introducing synthetic HDLs. The only thing we know is dead in the water is torcetrapib， not the whole idea of raising HDL， says Michael Miller， director of preventive cardiology at the University of Maryland Medical Center， Baltimore.

4. iii 本段分析了可能导致torcetrapibl临床试验失败的原因，后半段指出如果以上推测正确，那么未来的.药物可借鉴这个试验，设法避免torcetrapib的缺陷，研制出有效的药物。viii选项无法涵盖后半段的意思。
5. ix 见首句。
6. v
7. A 见第二段。题目中administer一词意为用药，subject一词为实验对象之意。
8. B 见第四段… to raise levels of HDLs， which ferry cholesterol out of artery- clogging plaques to the liver for removal from the body.即HDLs的作用最终是将 choleserol清除出人体：… for removal from the body。
9. B 见第四段But HDLs are complex and not entirely understood.
10. C 见第二段… plus a cholesterol-lowering statin，即statin是可以降低cholesterol的。
