One in every five young people has a sleep problem, so you’re not alone．Getting enough sleep has become as important as eating vegetables and exercising regularly．It’s very important for your body．

　　Most young people only get seven hours of sleep each night, when they actually need nine hours．And making up for lost sleep during the week by sleeping on weekends．It doesn’t really work．In fact, sleeping late on weekends may actually do you more harm than good, if you have sleep problems．

　　What happens if you don’t get enough sleep?If your sleep problem continues for a few nights, you could suffer serious problems．Lack of sleep can affect learning and memory．Worse, if your sleep difficulties last a long time, that could lead to anxiety or depression(抑郁)．Therefore, you’ve got to have some healthy sleep habits．Below are some suggestions：

　　GO TO BED AT THE SAME TIME?－including weekends, if possible．

　　WAKE UP AROUND THE SAME TIME EVERY MORNING When you wake up late just one morning during the week, it may disturb your body clock．This will make it hard for you to sleep that night．

　　DO SOMETHING RELAXING before going to bed．

　　EXERCISE DURING THE DAY．Don’t exercise right before going to bed．

　　AVOID DRINKING ALCOHOL．Alcohol makes you excited．This prevents you from falling asleep or wakes you up during the night．

　　DON’T SMOKE．Smoking is always bad for the body．Smoking before bedtime keeps you awake．If trying these tips over a couple of weeks does not help you, speak to your doctor．Do not take any sleeping pills without first asking your doctor．Many have strong side effects．

　　Fat on human beings is distributed(分为)in different ways．Some fat people have a large stomach and no waistline－which makes them look round, rather like apples．Others are fatter below the waist, which makes them appear pear-shaped．

　　There are two types of fat：external fat(fat under the skin)and internal fat(fat inside the body wall)．Doctors, who have been examining the relationship between health and fatness, have found that the pears’ have less internal fat, but the apples’ have more internal fat than external fat．This seems to be what causes the health problems．

　　The best treatment for fatness is to reduce the internal fat．But unfortunately, it seems that dieting simply makes an apple-shaped person into a smaller apple and a pear-shaped into a smaller pear．At the moment there is no known way of reducing the internal rather than external fat．

　　We all have to eat, but choosing the right foods can be hard．Many people also have trouble controlling how much they eat．Instead of eating reasonable portions of fruit, vegetables, whole grains, and other healthy foods, lots of people eat too many cookies and chips．Many people just eat too much food in general．

　　One result is an epidemic(流行病)of obesity(overweight)that has swelled the waistlines of millions of adults and kids．This increase in obesity has led to increases in the occurrence of diabetes, heart disease, cancer, and other illnesses．But for other people, food becomes the enemy．They worry so much about getting fat that they either severely limit what they eat or make themselves throw up right after eating．Doctors say that these people have eating disorders．

　　Eating disorders among teens are much less common than obesity is．Yet the health consequences of eating disorders can be just as severe．Not eating enough can lead to heart attacks, weak bones, organ damage, and fainting spells．Repeatedly throwing up causes chemical imbalances in the body, erodes teeth, and destroys the stomach lining．

　　Researchers are zeroing in on(aim at)what causes certain people to develop eating disorders, why some people are more at risk than others, and what kinds of education programs work best to keep people from taking drastic measures to lose weight or stay slim．It’s important to learn how to recognize signs of disordered eating in yourself and your friends, doctors say, because research shows that getting treatment early on is the key to a quick recovery．

　　You’ve probably heard of a lot about the Internet, but what is it?

　　The Internet is a computer network that uses the telephone system to connect together millions of computers around the world．

　　Maybe that isn’t very exciting but once you’re connected to the Internet, there are lots and lots of different things you can do．You can send electronic messages or “e-mails”to your friends(as long as they’re on the Internet, too), or you can sort through all kinds of information on something called the World Wide Web(www世界信息网)．You don’t need to know how the Internet works in order to use it, but if you understand the basics, it may help you work out any technical problems you have－and of course you can help your friends with your Net knowledge!You may think that your telephone is just for talking．But as long as you have the equipment, you can use a telephone line to send computer data(数据)as well as sounds．If you connect your computer with the telephone system it can receive information from, and send information to other computers(as long as they are connected with the telephone system, too)．

　　Because there is not an organization which operates the Internet, no one exactly knows how many people are connected to it．It’s thought that there could be 60 million people on the Net, connected up to over 15 million computers!

　　Personal computers and the Internet give people new choices about how to spend their time．Some may use this freedom to share less time with certain friends or family members, but new technology will also let them stay in closer touch with those they care most about．I know this from personal experience．

　　E-mail makes it easy to work at home, which is where I now spend most weekends and evenings．My working hours aren’t necessarily much shorter than they once were but I spend fewer of them at the office．This lets me share more time with my young daughter than I might have if she’d been born before electronic mail became such a practical tool．

　　The Internet also makes it easy to share thoughts with a group of friends．Say you do something funny－see a great movie perhaps－and there are four or five friends who might want to hear about it．If you call each one, you will get tired of telling the story．

　　With e-mail, you just write one note about your experience, at your convenience, and address it to all the friends you think might be interested．They can read your message when they have time, and read only as much as they want to．They can reply at their convenience, and you can read what they have to say at your convenience．

　　E-mail is also an inexpensive way to stay in close touch with people who live far away．More than a few parents use e-mail to keep in touch, even daily touch, with their children off at college．

　　We just have to keep in mind that computers and the Internet offer another way of staying in touch．They don’t eliminate(排除)any of the old ways．

　　Microsoft founder Bill Gates said that he planned to give away almost all of his vast fortune(财产)，largely to the cause(事业)of global health, during the course of his lifetime．With an estimated(估计)worth of more than ＄40 billion, according to Forbes, the project will be no small feat(功绩)for Gates．Having already provided the Bill ＆Melinda Gates Foundation with ＄24 billion to address global health issues, Gates said that eventually(最终地)his entire fortune will be put towards the cause except “a few percent left for the kids”．

　　So what has made the richest man in the world to channel his resources so heavily into one interest?Gates believes that“the equality of opportunity”in which Americans take such pride needs to extend to other nations around the world．Improving the health of the populations, he says, has proven to be an essential (基本的)method in helping poor countries to be financially successful．“National borders allow inequalities，”said Gates．“We all need to take a more global view, rather than just saying my country is doing well．We have to step up these health issues, knowing how few resources are going into them．”

　　Gates said that both his parents set up an example for him as a child．His father, William H．Gates, was the head of the local Planned Parenthood, and his mother, Mary, volunteered for the Untied Way．As he gathered his fortune, Gates knew he would eventually want to give back as well, but he didn’t expect to devote himself whole-heartedly to one project until he was about 60．However, Gates, 47, began to question his ability to wait that long．“It seemed there was a real time urgency,”Gates said．“I started to think, How many lives could I save before then?”

　　Do you find getting up in the morning so difficult that it’s painful?This might be called laziness, but Dr．Kleitman has a new explanation．He has proved that everyone has a daily energy cycle．

　　During the hours when you labour through your work you may say that you’re “hot”, that’s true．The time of day when you feel most energetic is when your cycle of body temperature is at its peak(最高峰)．For some people the peak comes during the forenoon．For others it comes in the afternoon or evening．No one has discovered why it is so, but it leads to such familiar monologues(自言自语)as：“Get up, John!You’ll be late for work again!”the possible explanation to the trouble is that John is at his temperature and energy peak in the evening．Much family quarrelling ends when husbands and wives realize what these energy cycles mean, and which cycle each member of the family has．

　　You can’t change your energy cycle, but you can learn to make your life fit it better．Habit can help, Dr．Kleitman believes．Maybe you’re sleepy in the evening but feel you must stay up late anyway．Counteract(对抗)your cycle to some extent by habitually staying up later than you want to．If your energy is low in the morning but you have an important job to do early in the day, rise before your usual hour．This won’t change your cycle, but you’ll get up steam and work better at your low point．

　　Get off to a slow start which saves your energy．Get up with a leisurely yawn(呵欠)and stretch．Sit on the edge of the bed a minute before putting your feet on the floor．Avoid the troublesome search for clean clothes by laying them out the night before．Whenever possible, do routine work in the afternoon and save tasks requiring more energy or concentration for your sharper hours．

　　There are some special traditions in Hawaii．People are very friendly to and always welcome visitors．They give visitors a lei, a long necklace made of beautiful flowers．Men often wear bright flowered shirts, and women often wear long flowered dresses．There are traditional Chinese, Japanese and Filipino holidays and all the holidays from the United States．They call Hawaii the Aloha States．Aloha means both hello and good-bye．It also means I love you．

　　Usually when people from different countries, races and traditions live together, there are serious problems．There are a few problems in Hawaii, but, in general, people have learned to live together in peace．

　　Hawaiians get most of their money from visitors, and most of the visitors come from the mainland and from Japan．There are so many people living in Hawaii now that there are residential(居住的)areas where there used to be farms．Some of the big sugar and apple companies have moved to the Philippines, where they don’t have to pay workers as much money．The families of the first people who came from the U．S．mainland own the important banks and companies．Japanese are also buying or starting business．
