I have hated getting up early all my life. The moment the alarm goes off in the morning, I feel sick. Nights, though, are different; Ill happily stay up and Ill do anything to escape an early start. This makes me an owl(猫头鹰), but I know many larks(云雀) who insist that dawn is the best part of the day. While I go to work sleepy they have been up for hours and even seem cheerful about it. But it is wrong to say that society is exactly divided into larks and owls. Surveys that explore what time of day people prefer to do activities show that only 20% of adults are true larks or owls. That leaves 80% of us-half of which lean towards one direction or the other, the other half are neither. Schools and work often start very early, and theres a sense of love for getting up early, while the owls are simply slovenly. But no one suggests that the larks are lazy for having an early night while owls are working. Fortunately science is on my side. Im not sleeping my life away or missing the best part of the day. Im behaving according to my genes(基因). Researchers have found that ones chronotype (睡眠类型)is largely genetic. So it seems that when I try to get up early I am fighting my genetics. With the help of an alarm clock I can force myself to get up early. But as soon as I fail to set the alarm my genes will return me to my old days.1.

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 andstay in touchwith issues we care about. The list goes on and on. 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. A new study finds that heavy Internet use may be connected to high blood pressure in an unlikely group - teenagers. So try to be a responsible guardian(监护人).The study results show that teens who spend at least 14 hours a week online are more likely to have high blood pressure. High blood pressure makes your heart andbloodvesselswork too hard. Over time, this extrastrainincreases your risk of a heart attack or stroke. High blood pressure can also cause heart and kidney disease(肾病). It is also closely linked to some forms of dementia(痴呆), a brain disease. 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. 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(智能手机) and to do some kind of physical activity. She also suggests that parents limit their childrens use of the smartphones or Internet to half an hour a day, five days a week.The Centers for Disease Control and Prevention（CDCP）says, 70 million, or 29%, of American adults have high blood pressure. The CDCP estimates that high blood pressure costs the United States $46 billion each year.4.
