Unit 4 Astronomy the science of the stars一、閱讀理解。The Internet plays a big part in human life. We use it for work and entertainment. We can find new recipes on the Internet or advice on staying healthy. We can even use it to learn a new language. We use the Internet to connect with family and friends and stay in touch with issues we care about. The list goes on and on. As far as the Internet being a part of our liveswell, that train has left the station. That expression means there is no going back. If you prefer boating, you can say that ship has sailed. So, there may be no going back to an Internet-free life. But can using the Internet too much be bad for our health? It might be, say researchers. Study results show that teens who spend at least 14 hours a week online were more likely to have high blood pressure. High blood pressure makes your heart and blood vessels work too hard. Over time, this extra strain increases your risk of a heart attack or stroke. High blood pressure can also cause heart and kidney disease. It is also closely linked to some forms of dementia, a brain disease. Dementia is marked by memory disorders, personality changes, and a reduced ability to reason. Lets introduce something about the study of it. The Henry Ford Hospital in Detroit, Michigan did the study. It involved 335 young people, from 14 to 17 years old. One hundred thirty-four of the teens were described as “heavy Internet users”. Researchers found that out of these 134 teens, 26 had high blood pressure. The researchers say the study is the first to connect heavy web use and high blood pressure. Other research has connected that heavy Internet use with health problems including anxiety, depression and obesity. The lead researcher of the study is Andrea Cassidy-Bushrow. In a statement she said, “Using the Internet is part of our daily life but it shouldnt consume us. ”For the purpose of the study, she explains, teens considered heavy Internet users were online on “average 25 hours a week. ”Ms Cassidy-Bushrow adds that it is important for teens to take “regular breaks from their puters or smartphones” and to do some “kind of physical activity. ”She also suggests that parents limit their childrens use of the Internet to two hours a day, five days a week. 【文章大意】互聯(lián)網(wǎng)如此有用并且融入我們的生活, 但過度使用它, 會導(dǎo)致多種健康問題。1.
