四六级

　　阅读一直都是英语六级复习的重点，距离18年6月份的考试还有较长时间，我们可以适当做一些英语阅读练习，提升自己的语感与在英语六级阅读中的猜词能力。以下是小编为大家整理的一篇英语六级阅读练习，供学习。

　　Questions 61 to 65 are based on the following passage.

　　Recent reports suggest that tea can cause brittle bones-but you'll probably be safe if you drink less than a gallon a day.

　　Do you fancy a cup of tea? We drink, on average, three mugs a day. But you might want to try another strong alcohol after hearing the case of a 47-year-old woman, published in the New England Journal of Medicine (NEJM), who developed brittle bones and lost all of her teeth after drinking too much tea.

　　Tea may not be so great for prostates (前列腺) either. Last year, research from the University of　Glasgow found that men who drank more than seven or more cups of tea a day had a 50% higher risk of　prostate cancer. And in 2009 a paper in the British Medical Journal showed that drinking very hot tea(70oC or more) increased the likelihood of esophageal (食管的) cancer.

　　Still gasping for that cup of tea? There is some evidence that tea can be good for you too, with　antioxidant properties, so maybe you're not actually drinking enough of the stuff.

　　The poor woman in the NEJM study is not alone. There are a few other cases of people who have　damaged their bones through too much tea. But she (like those in other studies) was drinking excessive　amounts: 100 - 150 tea bags a day to make 12 cups of tea. A litre of tea can contain up to 9mg of fluoride(氟化物), which in excess can cause skeletal fluorosis ( 氟中毒), reducing bone quality and causing pain and stiffening of the ligaments (韧带). Other studies show you generally need to drink a gallon a day for three decades to develop this condition.

　　You also shouldn't worry about the Glasgow study as it wasn't designed to show that drinking tea actually caused prostate cancer. All it proved was an association and people were only asked how much tea they drank at the start of the study, which went on for about 28 years.

　　The National Cancer Institute in the U.S. concludes that the evidence isn't good enough to say tea either harms or helps our health. However it does seem sensible in the light of the BMJ study to wait for your tea to cool down for a few minutes.

　　Black tea, which makes up 75% of the world's consumption, may have healthy properties from its plant chemicals called poly phenols(多酚), which are antioxidants. Green tea contains more poly phenols but isn't so nice to dunk digestives into.

　　A review of the evidence in the European Journal of Clinical Nutrition, sponsored by the Tea Council--which, the authors say, had no part in the study--found the research showed more than three cups of black tea a day reduced heart disease. It found no evidence of harm "in amounts typically consumed". So as long as you drink less than a gallon of tea a day you should be absolutely fine.

　　61. What can be inferred about tea from Paragraph 3?

　　A) Very hot tea may cause prostate cancer.

　　B) There may be a link between very hot tea and esophageal cancer.

　　C) Over-drinking tea is the cause of prostate cancer.

　　D) Drinking too much tea may worsen esophageal cancer.

　　62. Excessive intake of fluoride may

　　A) increase the likelihood of heart attack

　　B) cause the bone fracture

　　C) cause fluorosis in the blood

　　D) weaken the bone quality and hurt the ligaments

　　63. Which of the following instructions is encouraged to practice?

　　A) Drinking less tea in the future.

　　B) Drinking no tea at all.

　　C) Drinking tea that is not too hot.

　　D) Drinking green tea instead of black tea.

　　64. Black tea is considered as healthy drink because

　　A) it contains antioxidants

　　B) it is made from plant

　　C) poly phenols are added to it

　　D) it helps one digest

　　65. What can be inferred from the last paragraph?

　　A) Under no circumstance can you drink more than a gallon of tea a day.

　　B) Black tea can be seen as a cure for heart disease.

　　C) Drinking tea does no harm at all, regardless of how much you consume.

　　D) Tea Council's participation into the research may decrease its credibility.

　　61.B)。定位 由题干提示定位到第三段：Tea may not be so great for prostates either.Lastyear，research from the University of Glasgow found that men who drank more than seven ormore cups of tea a day had a 50% higher risk of prostate cancer.And in 2009 a paper in theBritish Medical Journal showed that drinking very hot tea(70。C or more)increased thelikelihood of esophageal cancer.

　　定位 推理判断题。本题考查读者对该段意思的准确理解。定位段指出“饮茶似乎对前列腺也没有益处。去年，格拉斯哥大学研究发现每天饮用超过七杯茶的男性患前列腺癌的风险会高出50%。2009年，《英国医学期刊》的一篇论文指出饮用过热的茶(70摄氏度或以上)会增加患食道癌的可能性”，故答案为B)。A)“过热的茶可能会引起前列腺癌”文中未提及，故排除;C)“饮茶过量是前列腺癌的原因”属于过度推断，故排除;D)“饮茶过量可能会使食道癌恶化”文中并未提及，故排除。

　　62.D)定位 南题干中的fluoride定位到第五段第四句：A litre of tea can contain up to 9mg offluoride，which in excess can cause skeletal fluorosis，reducing bone quality and causing painand stiffening of the ligaments.

　　详解 事实细节题。本题考查过量摄入氟化物的危害。定位句提到“一升茶水含有9毫克的氟化物，如果氟化物摄入过量，那么会造成人体骨骼氟中毒，骨质下降.韧带疼痛僵硬”，故D)为答案。A)“增加患心脏病的风险”与文意不符，故排除;B)“造成骨折”是对原文“骨质下降”的曲解，故排除;C)“造成血内氟中毒”与文意不符，故排除。

　　63.C)。定位 由题干中的instructions is encouraged to practice以及各选项定位到第七段第二句：However it does seem sensible in the light of the BMJ study to wait for your tea to cooldown for a few minutes.

　　详解 事实细节题。本题考查作者认为读者应采纳的建议。定位句指出“但是，鉴于《英国医学期刊》的研究，等几分钟让茶水放凉一些还是有意义的”，故C)为答案。A)“以后少喝茶”、B)“一点茶也不要喝”和D)“喝绿茶，不要喝红茶”都是对文意的曲解，故均排除。

　　64.A)。定位 由题干中的black tea定位到倒数第二段第一句：Black tea，which makes up 75% ofthe world’s consumption.may have healthy properties from its plant chemicals called polyphenols，which are antioxidants.

　　详解 事实细节题。本题考查红茶保健的原因。由定位句可知“红茶，占世界茶类饮用量的75%，可能因其含有植物化合物(即抗氧化的多酚)从而具有保健作用。”故答案为A)。B)“红茶由植物制成”、C)“红茶添加了多酚”和D)“红茶助消化”均与文意不符，故排除。

　　65.D)。定位 由题干中的last paragraph定位到原文最后一段：A review of the evidence in theEuropean Journal of Clinical Nutrition, sponsored by the Tea Council-which, the authors say, had no part in the study--found the research showed more than three cups of black tea a dayreduced heart disease. It found no evidence of harm "in amounts typically consumed". So aslong as you drink less than a gallon of tea a day you should be absolutely fine.

　　详解 推理判断题。本题考查堵着对该段意思的准确理解。由定位段可知“对由茶叶理事会赞助的《欧洲临床营养学杂志》的一项证据研究(作者表示茶叶理事会并未参与到研究中)发现，每日饮用三倍以上红茶可以减少患心脏病的概率，且没有标明饮用特订立的茶水会对人体有害。只要你每天音超不超过一加仑，那么绝对没有问题”。原味特别指处茶叶理事会未参与到研究中，可以推知或许会因为茶叶理事会的立场，会导致研究结果可信度下降，故答案为D)。A)“无论何时每日饮茶量绝对不超过一加仑”属于过度推断，故排除;B)“红茶可以治疗心脏病”属于过于推断，故排除;C)“无论饮用量为多少，茶完全无害”与原文逻辑不符，故排除。
