2014高考英语冲刺阅读理解专项 50-37AAmerican researchers say drinking tea may help strengthen the bodys defense system against infection（感染）. Doctors at Brigham and Womens Hospital in Boston, Massachusetts, did the study. The team studied a chemical found in black, green, oolong and pekoe tea. This chemical is an amino acid（氨基酸）called L-theanine. The scientists say it may increase the strength of gamma delta T cells. Thats the letter T, not the drink. Gamma delta T cells are part of the bodys defenses.First, the researchers mixed some of these cells with antigens（抗原）found in the amino acid. Antigens help the body react to infection. Then the scientists added some bacteria（细菌）. Within twenty-four hours, the cells produced a lot of interferon, a substance that fights infection. Cells not mixed with the antigens did not produce interferon.In the second part of the study, eleven people drank five to six cups of black tea every day. Ten other people drank the same amount of instant coffee. That is dried coffee mixed with hot water.Two weeks later, and again two weeks after that, the researchers tested the blood of all twenty-one people. They also looked at what happened when they added bacteria to the blood cells. They found that the tea drinkers produced five times more interferon after they started drinking tea. The coffee drinkers did not produce interferon.Doctor Jack Bukowski led the study. He says the antigens added to the gamma delta T cells were responsible for the increased reaction to the bacteria. He says the study also showed that the cells were able to remember the bacteria and fight them again the next time.Earlier research already has found that tea can help prevent heart disease and cancer. Doctor Bukowski says the new study must be repeated with more people. If the findings prove to be true, he says, then tea drinking might also help protect against bacterial infections. He says the amino acid L-theanine could be removed from tea and used as a drug to strengthen the bodys defenses.1. We may know from the text that _ can be found in different kinds of tea.A. Gamma delta T cellsB. L-theanineC. interferonD. bacteria 答案解析：答案为B。本题为推理题。由第一段 “The team studied a chemical found in black, green, oolong and pekoe tea.

When an imposter uses your name, your credit card number, or some other piece of your personal information for their own purpose in short, when someone takes your personal information without your knowledge its a crime, pure and simple.The biggest problem is that you may not know your identity（身份）has been stolen until you notice that somethings wrong: you may get bills for a credit card account you never opened, your credit report may include debts you never knew you had, a billing cycle may pass without your receiving a statement, or you may see charges on your bills that you didnt sign for, and even dont know anything about.If someone has stolen your identity, the Federal Trade Commission (FTC) suggests that you take three actions immediately.First, contact the fraud departments of each of the three major credit offices. Tell them to flag your file with a fraud alert（警告）including a statement that creditors should get your permission before opening any new accounts in your name.Then, ask the credit offices for copies of your credit reports. Credit offices must give you a free copy of your report if it is not correct because of fraud. Review your reports carefully to make sure no additional fraudulent accounts have been opened in your name or unauthorized（侵权的）changes made to your present accounts. In a few months, order new copies of your reports to check your corrections and changes, and to make sure no new fraudulent activity has occurred.1. Whats the subject discussed in the text?A. What you should do if your credit card is stolen. B. What you should do if your identity is stolen.C. What an imposter always does to make money. D. What the Federal Trade Commission is about.答案解析：答案为B。本题考查文章的主旨大意。本文的前半部分引出身份信息被盗的问题，后面的重点是告诉读者身份信息被盗后该如何做。故答案为B。2. What should you do first when you find your identity is stolen?A. Inform creditors not to open any new accounts in your name without your permission.B. Ask for copies of your credit reports and make sure no other frauds have been made.C. Keep ordering new copies to check what you have already changed and corrected.D. Always lock your ID card in your cupboard in case it should be stolen. 答案解析：答案为A。本题为推理题。由倒数第二段可知，当发现个人身份信息被盗后，首先要联系防伪部门，让他们关注你的资料，警告债权人在用你的名字开任何新的账户前应该得到你的允许。故答案为A。3. What is the most difficult thing for people to deal with identity frauds?A. No measures can work on the billing cycle.B. There is no strict law for this kind of behaviors.C. It might be a long time before you realize that.D. The FTC does nothing except for three suggestions. 答案解析：答案为C。本题为细节推理题。由文章第二段首句 “The biggest problem is that you may not know your identity has been stolen until you notice that somethings wrong”可知，直到你注意出了问题后才知道身份信息被盗是最大的问题。故答案为C。4. Which is the least possible if a fraud has happened to you?A. You may have debts in your credit card.B. You may find charges on your bills unauthorized.C. A new credit card may be opened in your name.D. The fraud departments can find out the imposter right away. 答案解析：答案为D。本题为推理题。由第二段冒号后面的内容可知，身份信息被盗后，你的信用卡会负债，你会收到未经授权的收费账单，还会出现以你的名字新开的信用卡。文中未提及防伪部门可以马上找到骗子，后文的措施也是在暗示找到骗子并不容易。故答案为D。
