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 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 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 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

Dear God, Now that I am no longer young. I have friends whose mothers have passed away. I have heard these sons and daughters say they never fully thanked their mothers until it was too late to tell them. I am blessed with the dear mother who is still alive. I appreciate her devotion more each day. My mother does not change, but I do. As I grow older and wiser, I realize what an extraordinary person the is. It’s sad that I am unable to say these words in her presence, but they flow easily from my pen. How does a daughter begin to thank her mother for life itself? For the love, patience and just plain hard work that go into raising a child? For running after a toddler(学步儿童), for understanding a moody teenager, and for tolerating a college student who knows everything? For wailing for the day when the daughter realizes what her mother really is? How does a grown woman thank a mother for continuing to be a mother? For being ready with advice when asked or remaining silent when it is needed? For not saying “I told you so.” when she could have voiced these words dozens of times? For being essentially herself-loving, thoughtful, patient and forgiving? I don’t know how to thank her, dear God, except to bless her and live up to the example she has set. I pray that I will look as good in the eyes of my children as my mother looks in mine. 1.We can infer from the passage that the author is . A. reserved and romantic B. cold and practical C. stubborn but responsible D. talkative and realistic 2.Compared with her friends, the author feels lucky because . A. she has her own lovely sons and daughters B. she is excellent in bringing up her own children C. it is too late to say thanks to her mother in her presence D. she still has the chance to express her appreciation to her mother 3.We can know from Paragraph4 that .

It was Saturday morning. I heard loud noises of moving furniture in the next room. I could almost feel the excitement of John who was soon going to get a room of his own. I remember my own feelings when I was 13. I knew how much he longed for his right to privacy when he was sharing a room with his younger brother, Robot. He said, “Mum, can I please have a room of my own? I could use Jeff’s. He won’t mind.” It was true that Jeff had graduated from college and flown from the nest. But would he mind? The room was the place where I told him a thousand stories and we had a thousand talks. As close as we were, though, the time came when Jeff needed a door between us. His life was spreading into areas that had less to do with family. I no longer could—or should—know everything about him. It turned out that getting Jeff’s permission was easy. He said, “Of course, Mum, it would be selfish of me to hold on to it.” Then his voice softened, “Mum, I won’t be living at home again— you know that.” Behind his glasses, his eyes were lit with all the love. There were no doors closed here—they had all opened up again. As John and I were cleaning the room, I fixed my eyes on Jeff’s things around me and could almost touch the little boy I knew was gone forever. I looked at the room and, in my heart, I let it go. To hold on would be, as Jeff said, selfish. Now it was time for John, shouldering through the door, his eyes bright with promise of independence, to disappear behind the door. It was time for letting go to happen again. 1.Which of the following is TRUE according to the passage? A. John was eager to get a room of his own. B. Jeff was moving to live with his brother. C. Jeff refused to let his brother have his room. D. Jeff volunteered to give his room to John. 2.The underlined sentence in the second paragraph probably means “Jeff_______.” A. finally flew out of the house B. would have less to do with his family C. needed his right to privacy D. got tired of those familiar stories 3.How did the author feel about his children’s sense of independence? A. Delighted. B. Confused. C. Jealous. D. Embarrassed. 4.It can be inferred from the passage that _______. A. the children did not like to live with adults B. all her three kids made the author feel depressed C. none of the members in the family thought the same way D. the author loved and missed the time together with her kids

Readers in Grenoble can now nibble (啃) fiction after Publisher Short Edition introduced eight short-story dispensers (自动售货机) around the French city. The free stories are available at the touch of a button, printing out on rolls of paper like a receipt. Readers are able to choose one minute, three minutes, or five minutes of fiction. “The feedback we got has been extremely positive. Just two weeks since its launch, more than 10,000 stories have already been printed. We are thrilled to see it working so well,” said the co-founder Quentin Pleple. “There are only eight dispensers in the city of Grenoble for now but we are planning to introduce more. We are getting requests from all over the world-Australia, the US, Canada, Russia, Grace, Italy, Spain and Chile.” Pleple said he and his team initially came up with the idea a couple of years ago when taking a break at a drink dispenser. “We thought it would be cool to have it for short stories,” said the publisher. ‘Then, we decided to make a difference: the short-story dispenser was born.” The French publisher hopes the story will be used to fill the “dead time” of a passenger. “In the bus or the subway, everyone can make the most of these moments to read short stories, poems, or short picture books,” said a statement from Short Edition. “And they can be sure to enjoy the quality.” The dispensers arc now in locations including Grenoble’s town hall, its tourist office and its library. The stories are drawn from more than 60,000 stories on Short Edition’s website. But there is a problem that users are not able to choose what type of story they would like to read. “Right now they can only choose the length. But that is exactly what really counts, isn’t it?” said Pleple. 1.Where can you probably see a short-story dispenser at present? A. In Chile. B. In Canada C. In France. D. In Italy. 2.What does the underlined word “launch” in the third paragraph probably mean? A. Coming into use. B. Being thrown away. C. Being found out. D. Breaking down. 3.Why did Short Edition provide short-story dispensers? A. To help people kill time in the journey. B. To encourage people to write short stories. C. To attract international tourists to Grenoble. D. To do research in the field of new technology. 4.In what aspect does the short-story dispenser need to improve? A. The length of the stories. B. The quality of the stories. C. The number of the stories. D. The choice of different stories.

In many countries, it is important to have many children. In the US, a few religious groups emphasize(强调) the importance of large families, but most people think one or two children are enough, and many couples have no children.1. Having many children would restrict the freedom and individualism(个人主义) of the parents as well as the other children in the family. Parents teach individualism by the way they raise their children.2. Parents begin teaching this self-reliance (自力更生)early , asking the child to do things on her own and praising her when she does. 3. They bring their children with them to church , to sporting events, to stores, and to social events.However , many places, such as expensive restaurants and live theatre productions , do not welcome children.Most formal social gatherings , those with written invitations do not welcome children either. Children, especially boys are expected to be energetic and assertive(果敢的). 4. Parents are expected to keep their children under control at all times, particularly in public places and in the homes of others.When a child misbehaves , only the child's parents may discipline him.5. Most parents discipline(训导) their children by rewarding good behaviors, not by punishing bad behaviors.While a spanking(掴) , a slap to the child's buttocks(屁股), is acceptable to some people, any punishment that wounds the child or leaves a mark is considered child abuse and is against the law. A.The relationship between American parents and their children is harmony. B.That doesn't mean, though, that they are allowed to "run wild" in public. C.Because taking care of a child is very costly, financially, emotionally, and socially, many couples view large families as a disadvantage. D.Other adults should not interfere (干涉)unless the child is doing something which may be harmful to himself. E.American children are expected to accept invitations to a formal party. F.Many parents want to expose(使暴露) their children to a variety of situations. G.They want to create a self-reliant, independent child, who can make it on her own by age eighteen.
