　　　 Maybe you never opened that account, but someone else did --someone who used your name and personal information to commit fraud(造假). 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 –it’s 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 something’s 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 didn’t sign for, and even don’t 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.

A

American researchers say drinking tea may help strengthen the body’s defense system against infection. Doctors at Brigham and Women’s 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. That’s the letter T, not the drink. Gamma delta T cells are part of the body’s 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. 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 body’s defenses.
