题目列表(包括答案和解析)
American researchers say drinking tea may help strengthen the body’s defense system against infection (感染).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,which 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 (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 body’s defenses.
72.We may know from the text that can be found in different kinds of tea.
A.Gamma delta T cells B.L-theanine C.interferon D.bacteria
73.Tea may help strengthen the body’s defense system because it helps .
A.the body to produce more interferon
B.the body to produce more Gamma delta T cells
C.to add some bacteria to the blood cells
D.to mix antigens with some of the cells in the body
74.According to Dr Bukowski, .
A.the findings of the study have already proved to be true
B.he bas taken some amino acid L-theanine from tea and made a drug with it
C.further study is needed to prove the findings true
D.he is not sure whether tea can help prevent heart disease and cancer
75.What would be the best title for this text?

TOKYO:Elderly people who drink several cups of green tea a day are less likely to suffer from depression(消沉,压抑),probably due to a “feel good” chemical found in this type of tea,Japanese researchers said.
Several studies have related drinking green tea to reducing psychological problems and Kaijun Niu,of Tohoku University Graduate School,and colleagues found people aged 70 and older who drank four or more cups of green tea daily were 44 percent less likely to experience depression.
Green tea is widely drunk in many Asian countries,including China and Japan.
Niu's team studied 1,058 healthy elderly men and women.About 34 percent of the men and 39 percent of the women had signs of depression,according to the study that was published in the American Journal of Clinical Nutrition.
A total of 488 participants(参与者)said they drank four or more cups of green tea a day,284 said they downed two to three cups daily and the rest reported having one or fewer cups daily.
According to the researchers,the apparent effect of drinking more green tea on alleviating depression did not become less after they considered other factors, such as social economic status,sex,diet,history of medical problems and use of antidepressants.
There was no link between drinking black or oolong tea,or coffee,and lower degree of depression.
The amino acid theanine,contained in green tea,which is thought to have a calming effect on the brain,may explain the beneficial effect shown in the current study,Niu noted,adding that more study is needed.
1.Which of the following do you think can best replace the underlined word “alleviating” in paragraph 6?
