Article: A new study suggests that early exposure to germs strengthens the immune system. That means letting children get a little dirty might be good for their health later in life. The study involved laboratory mice. It found that adult mice raised in a germ-free environment were more likely to develop allergies, asthma and other autoimmune disorders. There are more than eighty disorders where cells that normally defend the body instead attack tissues and organs. Richard Blumberg,who led the study,is a professor at Harvard Medical School in Boston,Massachusetts. He says,in 1989,medical researchers who sought to explain these diseases, first discovered that the increasing use of antibacterial soaps and other products, especially early in life, could weaken immune systems. Now, Dr. Blumberg and his team have what is the first biological evidence to link early exposure to germs to stronger adult immune systems. They say this exposure could prevent the development of some autoimmune diseases. In the adult germ-free mice, they found that inflammation in the lungs and colon was caused by so-called killer T cells. These normally fight infection. But they became overactive and targeted healthy tissue--an autoimmune condition seen in asthma and a disease called ulcerative colitis . Dr. Blumberg says the mice raised in a normal environment did not have the same reaction. He says their immune systems had been "educated" by early exposure to germs. Rates of autoimmune disorders are rising worldwide, but mostly in wealthier, industrialized countries. According to Dr. Blumberg, it might be high time that people were warned to be more careful with the early use of antibiotics and the prescription from their doctors. Rob Dunn is a professor of ecology and evolutionary biology at North Carolina State University in Raleigh. He says the new study does not mean people should stop washing. "Wash your hands , but don't do it with antibacterial soap. Let your kids play in a reasonable amount of dirt and get outside and get... Question: Where does this text most probably come from?

Q: Article: "Joe? Is chat you?" The woman speaking to me at he baseball game looked somewhat familiar, "Marci? " "It IS you ! " she exclaimed, smiling broadly. "God, it's good to see you again !" It was good to see Marci, too. Very often during the past few decades, I've wondered about her, I almost tried to reach her a few years ago after talking to a shared friend, who had indicated that the 1990s had been pretty rough for Marci. So, running into her at the baseball game was, at the very least, just happening by chance. We spent a few minutes talking about the business of our lives: kids and grandkids, husbands and houses, education and recreation. It's always a little upsetting to see how few words are required to summarize 32 years of living. We played a little "have you seen...?" and "did you know,..?" And we recalled the good old, bad old days we used to spend together. Then Marci grew quiet for a moment, looking out over the crowd walking about the marketing area at the stadium. "You know, Joe." she said, "I've always wanted to tell you...how...you know...how sorry I am for the way I treated you." Hearing that, I felt I was suffering extreme embarrassment. One does not like to remember when one has been rid of by others roughly and suddenly. "It's OK." I said. "No big deal." At least, I thought to myself, not now. "But I was so stupid: she continued. Yes, you were. I thought. "We were both pretty young:' I said. "I know," she said. "But that's no excuse for..." She hesitated. then continued. "It's just always bothered me, remembering how mean I was to you.And I've wanted to tell you that I'm sorry. So...I'm sorry." The smile on her face was warm and sincere, and there was something in her eyes, it looked a lot like relief-- _ since she had played Wif'fle ball with my heart. "OK:'I said. "Apology accepted! Overcome by the sweetness of the moment. I reached an arm around her and gave her a quick hug Just then, the... Question: What happened after they broke up? Yes or no, is the answer "Joe couldn't forget Marci and tried to get in touch with her."?
A: No

Article: As the mobile phones so widely appear in our daily life, someone said it would be cool if you didn't have a mobile phone nowadays. It might be true to some extent, but as for an adult, a mobile means contact. It connects your work, relatives, friends, etc. It should do great deeds for us. Months ago, my uncle gave his dear son a phone, because my nephew's school is far from his home. He can only come back once a term, and the phones haven't been so expensive yet. However, someone has criticized the young people for playing on mobiles, but not using. They are fond of sending messages, taking pictures and so on. They buy expensive, high level and fashion types for showing. They play on the mobiles day in and day out ..... Holy cow! So, what happens to youngsters around you? Do they have a phone? What do they use it for? Do you think it's necessary for teenagers who are still in school to have a phone? POSTER 1: In my view, mobile phones are only a tool for communication purpose, just like any other tools which have the potential to be misused. In my opinion, I can see young people using it for security reason, emergency purpose, etc. If the parents can afford to pay big phone bills for their kids, well, that's their business, like the old saying goes, _ --- Mary Smith POSTER 2: From psychological point of view, teenagers are more likely to be relaxed or pleasure-oriented. They would like to make something different. Buying brands that are considered "COOL" is important to them. They want others to like and admire themselves, and sometimes, even exaggerate their own personality to show off. This can be seen as a kind of psychology during this certain range of age. --- Dick Gates Currently, people should tend to be more sociable, and age should not be seen as a barrier for teenagers to own their phones. They also need to set trends on the social circuit . But here parents should play an important role in controlling their children about how to use the phones more properly. Question: What is Dick Gates' attitude towards whether teenagers should use mobile phones? Yes or no, is the answer "Objective."?
