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 defense.
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 (抗干擾素).
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 that 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 by 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 the tea and used as a drug to strengthen the body’s defenses.
1.We may know from the text that _________ can be found in different kinds of tea.
A. L-theanine B. Gamma delta T cells
C. interferon D. bacteria
2.Tea may help strengthen the body’s defense system because it helps _________.
A. to add some bacteria to the blood cells
B. the body to produce more gamma delta T cells
C. the body to produce more interferon
D. to mix antigens with some of the cells in the body
3.According to Dr Bukowski, _________.
A. the findings of the study have already proved to be true
B. further study is needed to prove the findings true
C. he has taken some amino acid L-theanine from tea and made a drug with it
D. he is not sure whether tea help prevent heart disease and cancer
4.What would be the best title for this text?
A. Tea Is Better than Coffee B. Our Body Needs Tea
C. Tea Can Help Prevent CancerD. Tea May Help Fight Infection

Steven Spielberg was not a scholar, and his classmates teased him. Rather than read, the kid really preferred running around with an 8mm camera, shooting home?made movies, which he showed to friends for a small fee.
In his first year of high school, he dropped out. But when his parents persuaded him to return, he was mistakenly placed in a learning?disabled class, which lasted one month. Only when the family moved to another town did he land up in a more suitable high school, where he eventually graduated.
After being denied entrance into a traditional film?making school, Steven Spielherg enrolled in English at California State University at Long Beach. Then in 1965, he recalls, in one of those serendipitous moments, his life took a complete turn. Visiting Universal Studios, he met Chuck Silvers, an executive in the editorial department. Silvers liked the kid who made 8mm films and invited him back sometime to visit.
He appeared the next day. Spielberg, dressed in a dark suit, carrying his father's briefcase with nothing inside but a sandwich and candy bars walked confidently up to the guard at the gate of Universal and gave him a casual wave. The guard waved back. He was in.
“For the entire summer,” Spielberg remembers, “I dressed in my suit and hung out with the directors and writers, including Silvers, who knew the kid wasn't a studio employee, but winked at him. I even found an office that wasn't being used, and became a squatter (擅自占用他人房子的人). I bought some plastic tiles and put my name in the building directory: Steven Spielberg, Room 23C.”
It paid off for everyone. Ten years later, the 28?year?old Spielberg directed Jaws, which took in $470 million, then the biggest grossing movie of all time. Dozens of films and awards have followed because Steven Spielberg knew what his teachers didn't—talent is in the eyes of the filmmaker.
1.Why was Steven Spielberg laughed at by his classmates?
A.He was the youngest boy.
B.He was too short for his age.
C.He liked to fight with other boys.
D.He didn't care much about his lessons.
2.Why did Steven's friends pay him some money?
A.To see his movies.
B.To use his camera.
C.To look at his photos.
D.To include them in the movie.
3.What did Steven Spielberg intend to do after graduating from high school?
A.Study English at a college.
B.Become a newspaper editor.
C.Work for Universal Studios.
D.Go to a traditional film?making school.
4.What could have changed Steven Spielberg's life?
A.Being dressed in a suit.
B.Meeting Chuck Silvers.
C.Missing a film?making school.
D.Working for Universal Studios.
5.What can we learn from the story?
A.Always follow our dream and we can make it.
B.We need someone to help us realize our dreams.
C.Anyone can become a film director if he wants to.
D.We should grasp the opportunity that comes our way.
