　　A study finds that not enough morning light causes teenagers not to get enough sleep at night．“As teenagers spend more time indoors, they miss necessary morning light．Day light is needed to keep the balance of the body's 24-hour biological system(生物系统), which regulates(调节)body temperature and sleep styles, ” reports Dr．Mariana Figueiro．“These teenagers who receive little morning light are going to bed later, getting less sleep and doing badly in tests．They are more likely to fail in their exams．”

　　In the study, Dr．Figueiro asked 11 students in Grade 8 to wear special glasses to prevent blue morning light from reaching their eyes．At the end of the 5-day study she found that they fell asleep 30 minutes later than usual．

　　Throughout her research, Dr．Figueiro has been very worried about teenagers going to bed too late．The problem is that today's schools require teenagers to be in school very early in the morning．These students are likely to miss the morning light because they often go to school before the sun is up or as it's just rising．

　　Furthermore(此外), the schools are not likely to provide enough electric light to keep the balance of this biological system．Our biological system is much more sensitive(敏感的)to blue light．Therefore, having lots of light in the classroom does not make sure that there is enough light to keep our biological system balanced．

　　Nobody is happy all the time, but some people are really happier than others．Here are some tips for you to be happy．

　　Make enough money to meet your basic needs： food, shelter, and clothing．In the US, that magic number is ＄40, 000 a year．Any money you make beyond that will not necessarily make you happier．Once you make enough money to support your basic needs, your happiness is not affected by how much money you make．

　　________ Or move to where other members are－so you can see them more．Now, people follow jobs around the country and sometimes around the world．As a result, our relationships with our friends and family have a far greater impact(影响)on our happiness than our jobs do．So next time you think about moving, consider a place where most of your friends and families live．

　　Find happiness in the job you have now．Many people expect(期待)the right job to change their level of happiness．But happiness research makes it clear that changing jobs can't bring you happiness．If you want, you will make the best of any job．If you have good relationships with people, you won't depend on(依赖)your job to give your life a greater sense of meaning．You will find it in your interactions with the people you care about．

　　If you are unhappy for a long time, you should ask an expert(专家)or a doctor for help．I hope you will be happy all the time．

　　I still remember the last time when two of my children and I went to the playground．It had rained during the night and the playground was very muddy(泥泞的)．They had just put on clean clothes, so I was a little worried about the pools of water on the playground．It was not long before Kathy got her beautiful skirt dirty on the playground．She dug through the rocks．I was about to blame her for getting her clothes dirty when she ran towards me with a smile on her face．When she got to me, she handed me a little heart-shaped rock and said, “Here Mom! Here is a heart for you－just because I love you! Keep it! ” with tears in my eyes, I thanked her．

　　Should I blame her for getting her clothes muddy? No way! I still have that little heart-shaped rock．It is one of the best gifts that I have ever received．I realize that many times it is not necessary for us adults to worry about the small things our children do．Let them do what they'd like to．

　　I will spend a lot more time on the playground with my children．I'm sure I will learn a lot from the children．It reminds me of some years ago when my grandfather told me, “You would not enter the kingdom(王国)of happiness until you pretended(假装)to be a small child．”

　　After having exercise in the gym tonight, I just had a shower to relax for a while．While calming myself down with soft music, I started to recall what happened in the daytime and wrote it down．

　　The accident that gave me much thought happened on my way to the gym after work．When I walked about half way, I saw that many people surrounded something on the roadside and they were worried and shocked．I joined them and found there was a man lying on the ground．I noticed that he was a young man around 30 years old．He Looked so pale and very thin．From his dressing, I simply judged that he worked in the office．The hospital ambulance(救护车)came over and some nurses did the regular check for him．A nurse said that there was nothing serious with him but his body was very weak, which should be caused by overwork and less exercise．

　　It's a really sad thing for a young person to fall down in the street．A couple of days ago, I read a magazine mentioning that there is an increasing number of businessmen and white-collar workers with unhealthy bodies．Under huge pressure, they put all their time and energy to work and can't find enough time for a good meal or a good sleep, let alone exercise．But they forget that without health, work is equivalent to zero．

　　As I realize how important it is to put the health matter ahead．I am willing to do more exercise．I know exercise can bring me enjoyment and health．I know without health, even a most successful career and a great quantity of money will lose their meanings．

　　When I got out of the gym, I felt that every cell(细胞)in my body was refreshed and I was able to have more energy to write the words above．The feeling in sweat was wonderful!

　　Popeye the Sailor first became a popular cartoon about eighty years ago．The sailor in that

　　cartoon ate lots of spinach(菠菜)to make him strong．People watched him, and they began to buy and eat a lot more spinach．Popeye helped sell 33 percent more spinach than before! Spinach became a necessary part of many people's diets．Even some children who hated the taste began to eat the vegetable．

　　Many people thought that the iron in spinach made Popeye strong, but this is not true．Spinach does not have any more iron than any other green vegetable．

　　People only thought spinach had a lot of iron because the people who studied the food made a mistake．About one thousand years ago, a group of people studied what was inside vegetables．This group said that spinach had ten times more iron than it did．The group wrote the number wrong, and

　　everyone accepted it．

　　Today, we know that the little iron there is in spinach cannot make a difference in how strong a person is．However, spinach does have something else which the body needs-folic acid．

　　It is interesting to point out that folic acid can help make a person strong．Maybe it was really the folic acid that made Popeye strong all along．

　　Did you know that a turtle(乌龟)can lay 12 eggs in one minute? A large sea turtle lays around 150 eggs at a time．She lays all these eggs in just a few minutes．

　　Large sea turtles live in the warm seas of the world．Except for when they lay their eggs, they spend their whole lives in the water．When it is time to lay their eggs, the females swim to land．

　　They usually return to the place where they themselves were born．How they find their way back there is unknown．

　　When they reach shore, the big, heavy turtles crawl slowly up to the high water mark．Using their flippers, they pull themselves along the sand．They must struggle like mountain climbers．When they finally reach dry sand, they rest before beginning the difficult task of laying eggs．

　　The turtles lay the eggs in deep holes and cover them with warm sand．The sand protects the eggs from harm．Then the females leave them．After a few weeks, if you happened to be walking along the beach, you might see the sand begin to shake．You may see tiny black balls coming out of the sand．The tiny heads of baby turtles!

　　Going to sleep may seem pretty boring compared with all the fun things you do while you are awake, But there's a lot going on in your mind and body while you are sleeping．

　　Sleep, in fact, is as important to your survival as eating and drinking．Sleep improves your mood, makes you a better athlete and helps you remember and understand what you learned during the day．While you sleep, your body temperature drops．Your heart beats more slowly, A chemical that controls growth, which is called a hormone(荷尔蒙),moves into your bloodstream．Scientists think that sleep brings back energy and improves your immune(免疫)system．

　　Sleep is like a school day：it's divided into different stages．When you are awake, your brain waves move quickly．As you begin to relax and fall into the first stage of sleep, your brain produces slower-moving waves and you lose awareness of your surroundings(环境)．As you fall into deeper sleep, your body repairs itself from the normal wear and tear of daily life．Then, as you begin to drift back into a lighter sleep, your mind becomes more alert(警觉的)，and your dreams begin．You are in REM sleep．

　　REM is the name for the rapid eye movement that happens while you are dreaming．During REM sleep, your eyes move back and forth behind "our lids, as though you were watching a movie．During other stages of sleep, you might move in bed, but during REM sleep you're not making any movement．That's probably because if you could move, your body would act out your dreams．As you get closer to waking up in the morning, you spend more time in REM sleep than in deep sleep, so you dream more．Researchers know that during REM sleep the part of the brain that deals with learning and thinking is very active．

　　Getting too little sleep can affect your personality．Experts recommend that children get at least nine hours of sleep a night．

　　It is not unusual for us to gather with our nearest and dearest at weekends．But do you know that holidays, much like relationships, can be "made, maintained and broken" through conversations? Deborah Tannen, a Georgetown University professor, believes so．She offers suggestions to improve communication at the holiday table and beyond．Let's take a look．

　　A round dining table is best for promoting(促成)a lively conversation because everyone faces one another．

　　Don't seat grandparents at the ends of a rectangular(长方形的)table, even though it is the traditional place of honor．Elderly people may feel lonely there because they will be unable to hear or keep up with a conversation．

　　Women prefer to face each other and make eye contact when they talk．Men might look around at other things．"Guys may be more relaxed keeping their eyes on the TV," says Tannen．"They'll still be listening, though．"

　　Be aware that people have different ways of talking．Be aware of people who seem left out．If you feel you are doing ail the talking, hold back to give others a chance to join in．If you feel you aren't getting a chance to speak, try pushing yourself to start talking before it seems natural or polite．

　　Some families find that gatherings go more smoothly(顺利地)if they take part in an outdoor activity．Going to a park for a walk may be more enjoyable than sitting around chatting．
