雅思阅读-练习十七(总分：31.00，做题时间：90分钟)一、Passage 1(总题数：0，分数：0.00)二、Questions 1-3Choose the correct letter, A, B, C or D.(总题数：3，分数：3.00)1.The main topic discussed in the text isA．the damage caused to US golf courses and golf players by lightning strikes.B．the effect of lightning on power supplies in the US and in Japan.C．a variety of methods used in trying to control lightning strikes.D．a laser technique used in trying to control lightning strikes.（分数：1.00）A.B.C.D. √解析：[解析] 这道题目是关于文章主题的，很难定位，一般都是放到最后来做。
但是本文我们可以直接通过文章的标题来确定这道题目的答案：Striking Back at Lightning With Lasers，首先肯定是与对抗闪电有关的，直接排除A和B，将范围缩小到C和D，C和D的主要区别在于究竟文章是描述了多种方法还是一种激光技术，很明显题目中有Lasers，答案确定为D。
通过阅读文章第二段，同样可以确定本题的答案。
A项和B项都出自第一段，是引出文章的内容，不可能是主题。
C项比较具有迷惑性，但忽略了laser这一重要的技术基础。
2.According to the text, every year lightningA．does considerable damage to buildings during thunderstorms.B．kills or injures mainly golfers in the United States.C．kills or injures around 500 people throughout the world.D．damages more than 100 American power companies.（分数：1.00）A. √B.C.D.解析：[解析] 这是一道充满陷阱的题目，出题者煞费苦心地为考生挖出了三个陷阱，考生需要做的是一一识破这些陷阱，选出正确答案。
雅思阅读真经5答案【篇一：真经5解析】lass=txt>5. safer=better，took over=alternatives，所以答案是freon。
6. 注意inventing=patentedq1: 请问第一篇冰箱的发明的第2和3空怎么定位，我在原文找不到….a: 第二第三题对应正文第四段最后一句话。
原文：and another made by physician jg, and developed vapor-compression refrigeration for the brewing and meatpacking industries.题干：and commercial refrigeration was applied to as well as industries. 对应：for=applied to; and=as well as定位词：commercial refrigerationq2: 还是冰箱那篇，为什么第5个空不能填alternatives？在原文中不是刚好接在比较级better后面吗？a: 第五题对应正文第五段第三句话。
原文：engineers worked until the 1920s to come up with better alternatives, one of which was freon.题干：the safer took over it in 1920s.对应：better=safer; come up with=took over定位词：1920s请注意，填alternative不是最优答案，最准确的是氟利昂freonreading passage 2 阿尔弗雷德诺贝尔3. 判断填形容词。
不能填explosive，因为炸药都要爆炸，所以爆炸不是炸药的风险。
可控的、安全的爆炸才是问题。
对应原文15页第5行：the safety problems。
雅思英语阅读练习题及答案：第一篇内容摘要：The failure of a high-profile cholesterol drug has thrown a spotlight on the complicated machinery that regulates cholesterol levels.★Why did a promising heart drug fail?Doomed drug highlights complications of meddling with cholesterol.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 pressure5. 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 irreversibleaccumulation of cholesterol in the body. "You're blocking a physiologic mechanism to eliminate cholesterol and effectively constipating the pathway," says Kashyap.Going up7. 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.(613 words nature)Questions 1-7This passage has 7 paragraphs 1-7.Choose the correct heading for each paragraph from the list of headings below.
