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 lives—well, 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.Let’s 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 shouldn’t 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 computers or smartphones” and to do some “kind of physical activity. ”She also suggests that parents limit their children’s use of the Internet to two hours a day, five days a week.【文章大意】互联网如此有用并且融入我们的生活, 但过度使用它, 会导致多种健康问题。

The effects of coffee consumption on health have long been a subject of conflict and uncertainty. Since the 1980s, some have spoken out against coffee as it’s harmful to health, while others have welcomed coffee for its supposed benefits to health.According to a scientific report, mild coffee consumption, three to five cups per day, can be taken as a healthy dietary pattern, along with other healthful behavior. The report also says that coffee consumption helps reduce the risk of heart disease and it protects against Parkinson’s disease.According to Dr. Donald Hensrud of Mayo Clinic, high consumption of coffee has health risks. Dr. Hensrud mentions the dangers of high coffee consumption for people with a certain illness that slows the breakdown of caffeine in the body. Some studies said that drinking two or more cups of coffee daily can actually increase the risk of heart disease in these people.According to conclusions from a recent study led by Dr. Gregory Marcus, a doctor from the University of California, San Francisco, daily moderate consumption of caffeine, less than 4 cups, is not associated with these issues.Until the scientific community reaches a general agreement on the effects of coffee consumption on human health, it will be up to the individual to decide whether the benefits of drinking coffee are greater than the risks.When informed of these possible health benefits and harm of drinking coffee, Harwood, a high school student stated, “Even though there might be some negative effects of drinking coffee, for the most part, coffee drinking sounds good for health. Not to mention I need coffee to stay awake.”【解题导语】本文是一篇说明文。

After his death, one of Pangu’s eyes became the sun and the other, moon. His breath was the wind and his muscles turned into mountains.

Unit 4 Astronomy the science of the starsⅠ阅读理解Got big plans for Friday night? That’s OK, we don’t either.Guess we’ll all have to make do by watching the celestial(天空的) show that will take place that night.First, there will be a full moon. That’s always fun, but this one will be a little more special. It’s known as a “snow moon”. The name es from the fact that the heaviest snows usually fall during February, according to The Old Farmer’s Almanac.But if that’s not special enough, there’s also an eclipse(月食) that night. It’ll be a penumbral lunar eclipse, meaning it’s a partial eclipse that leaves sections of t he moon darkened by the earth’s shadow. No, it won’t be as spectacular as those “blood moon” eclipses. It’ll be subtler. The level of darkness it reaches during the eclipse may or may not be apparent；it just depends on where you are when you view it.In North America, the eclipse begins at 5：34 p．m. ET and ends at 9：53 p．m. ET, according to the astronomy website EarthSky. The eclipse will be at its height around 7：44 p．m. ET.If that’s still not enough, let’s throw in a et(彗星) to the night’s festivities.et 45P (it has a much longer name, but we won’t burden you with it here) is visible as it flies by the earth. The et will get within 7.4 million miles of the planet as it makes its closest approach this weekend, according to Universe Today.et 45P will be most visible a couple of hours after the eclipse, so look to the skies again around 3 a．m. ET Saturday and find the greenishblue light with a tail.And don’t forget, a total bigtime solar eclipse will streak across the United States on August 21st.【解题导语】本文是说明文，介绍了星期五晚上将会发生的天文现象。

Unit 4 Astronomy the science of the stars李仕才【阅读理解插花】The more hours young children spend in child care， the more likely they are to turn out aggressive and disobedient by the time they are in kindergarten, according to the largest study of child care and development ever conducted。
Researchers said this correlation(相关性) held true regardless of whether the children came from rich or poor homes， were looked after by a relative or at a center, and whether they were girls or boys.What is uncertain, however, is whether the child care actually causes the problem or whether children likely to turn out aggressive happen to be those who spend more hours in child care。
