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 youdrink 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 totry another strong alcohol after hearing the case of a 47-year-old woman, published in theNew England Journal of Medicine (NEJM), who developed brittle bones and lost all of her teethafter drinking too much tea.
Tea may not be so great for prostates (前列腺) either. Last year, research from theUniversity of Glasgow found that men who drank more than seven or more cups of tea a dayhad a 50% higher risk of prostate cancer. And in 2009 a paper in the British Medical Journalshowed 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 whohave damaged their bones through too much tea. But she (like those in other studies) wasdrinking excessive amounts: 100 - 150 tea bags a day to make 12 cups of tea. A litre of teacan 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 (韌帶). Other studiesshow 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 thatdrinking tea actually caused prostate cancer. All it proved was an association and people wereonly asked how much tea they drank at the start of the study, which went on for about 28years.
The National Cancer Institute in the U.S. concludes that the evidence isn't good enough tosay tea either harms or helps our health. However it does seem sensible in the light of the BMJstudy 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 propertiesfrom its plant chemicals called poly phenols(多酚), which are antioxidants. Green tea containsmore 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 TeaCouncil--which, the authors say, had no part in the study--found the research showed morethan three cups of black tea a day reduced heart disease. It found no evidence of harm "inamounts typically consumed". So as long as you drink less than a gallon of tea a day youshould 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.
參考答案：
61.B)。本題考查讀者對該段意思的準確理解。定位段指出“飲茶似乎對前列腺也沒有益處。去年，格拉斯哥大學研究發現每天飲用超過七杯茶的男性患前列腺癌的風險會高出50%。2009年，《英國醫學期刊》的一篇論文指出飲用過熱的茶(70攝氏度或以上)會增加患食道癌的可能性”，故答案為B)。
62.D)。本題考查過量攝入氟化物的危害。定位句提到“一升茶水含有9毫克的氟化物，如果氟化物攝入過量，那么會造成人體骨骼氟中毒，骨質下降.韌帶疼痛僵硬”，故D)為答案。
63.C)。本題考查作者認為讀者應采納的建議。定位句指出“但是，鑒于《英國醫學期刊》的研究，等幾分鐘讓茶水放涼一些還是有意義的”，故C)為答案。
64.A)。本題考查紅茶保健的原因。由定位句可知“紅茶，占世界茶類飲用量的75%，可能因其含有植物化合物(即抗氧化的多酚)從而具有保健作用。”故答案為A)。
65.D)。本題考查堵著對該段意思的準確理解。由定位段可知“對由茶葉理事會贊助的'《歐洲臨床營養學雜志》的一項證據研究(作者表示茶葉理事會并未參與到研究中)發現，每日飲用三倍以上紅茶可以減少患心臟病的概率，且沒有標明飲用特訂立的茶水會對人體有害。只要你每天音超不超過一加侖，那么絕對沒有問題”。原味特別指處茶葉理事會未參與到研究中，可以推知或許會因為茶葉理事會的立場，會導致研究結果可信度下降，故答案為D)
