　　Celia was shocked．She had always been in good shape during high school, but now, in her first year of college, she was suddenly ten pounds heavier．“My friends and I often had pizza or ice cream when we studied late at night,” she said, “and I was always drinking Coke to stay awake．”

　　Celia's experience is common．Many students enter college and find it so different that they cannot deal with changes properly．They're away from their parents and in a new stressful environment．Pressures together with freedom to sleep and eat whatever they please cause many students to experience the “Freshman 15”：gaining weight suddenly in their freshman year of college．

　　Most students do not realize that the “Freshman 15” can cause some serious health problems．Of course, college-age adults are still developing bone mass, so gaining some weight is normal．Sudden weight gain, however, puts too much strain(负担)on the heart and lungs, resulting in little energy and some difficulty thinking and remembering．In later life, it can lead to heart disease, diabetes, obesity, and possible cancer．

　　The solution to the “Freshman 15” is simple－pay attention to developing good habits! In general：

　　●Eat normal-sized meals at regular times．Eat slowly and enjoy it, so you don't need to go back for more．

　　●Keep only healthy snacks in your room－and don't snack too often!

　　●Control drinking and smoking．Alcohol has a lot of calories, and smoking too much makes exercise difficult．

　　●Exercise regularly! Even just 30 minutes a day－such as walking quickly to class from your dorm－will make a big difference!

　　The following diaries were written by an Australian boy named Tony．He was on holiday with his family in South Asia．

　　27 December, 2010

　　This morning I read an email about a boy in hospital looking for his father and I finally thought of a way to help．I took my camera to the hospital and took photos of the boy．Now I'm going to set up a website on my dad's computer, upload the photos and add his name and information of the hospital．

　　Hopefully it will help!

　　2 January, 2011

　　At the end of the trip, I learned that the boy found his father! His Swedish uncle saw the email on my webpage and arranged the meeting．Is it my website that has made such a success? But at least I've done something．

　　We're returning home tomorrow but I will remember the experience and tell my friends：No matter what we are．We can think of a way to help others．

　　The Wall Street Journal Asia Edition(U．S．), the Globe and Mail(Canada), the Guardian(U．K．)，among other foreign news agencies，have recently published articles on China's earthquake relief．They have all praised the earthquake relief efforts made by the Chinese government．

　　The Wall Street Journal Asia Edition published an article on May 21 saying that on the eighth day of the most serious natural disaster to hit China in decades, rescuing survivors from the ruins had been quickly replaced by the formidable challenge of helping them．The article said that people overseas have been deeply impressed by earthquake relief efforts by the Chinese government．

　　The Associated French Press(AFP)reported on May 21 that China has become more open during the campaign．Aircraft loaded with relief supplies from Ukraine，Russia，the United States, Singapore and other countries have arrived in disaster areas in southwestern China．

　　The Associated Press(AP)published an article on May 21 reporting that China is making great efforts to deal with an extremely difficult task caused by the earthquake how to provide temporary shelter for so many people．The article said that many tents have been built；and food and medical care are provided to the people whose lives have been completely disturbed by the earthquake．

　　The Global and Mail of Canada published an article on May 20 that said the rapid earthquake relief work in Sichuan demonstrates China's powerful economic strength．An article carried in the British Guardian said that one week after the Sichuan earthquake，China began a three-day national mourning period at 14：28 on may 19, and all Chinese people stood in silence for three minutes in memory of the victims．

　　The ongoing search and rescue action is encouraged by one miraculous survivor after another：Chinese officials said that，so far, no epidemic had occurred after the earthquake．

　　Last year in my high school child-development class，each student had to take the “Think-It-Over” baby home for a night to get a taste of parenthood．

　　It was a Friday night when my turn came to take the 10-pound plastic doll home．The doll really did look like a live baby from a distance．It even had a pleasant baby powder smell．I took the baby home and named him Tyler．

　　My friends and I went out for supper that night．As it was rather cold, I decided to wrap Tyler in a blanket and carry him in that way．When I walked into the restaurant, I noticed some very strange looks and quite a few raised eyebrows．My friends and I decided to make a game out of the whole situation．I stood in the corner pretending to rock Tyler to while my friends kept looking into the blanket and said, “Oh, how lovely．” I could not but laugh．And although it was funny to my friends and me, some of the people did think it was so funny that I had a baby．I overheard one couple say，“Why would she put a baby here? ” These people were giving me rude looks and forming judgments about because they thought I was a teenage mom．Others just smiled at me pathetically(同情地)and felt sorry for me because I was only a child with a child．during our meal，my friends and I received strange looks from the others in the restaurant．I was so glad to finally go home．

　　I learned a lot through my experience with the“Think-It-Over”baby．The doll Tyler strengthened my thinking I was not ready to be a parent, but it also made me aware of the larger picture．It opened my eyes to the judgments people make about it．People do not realize that some things are not the way they seem．I was only trying it around for a class project．The people in the restaurant were so quick to judge because they thought I was a teenage mom．I sometimes catch myself judging people I not know, just because of the first impression they give．In reality, I have no idea about real stories．We should all be slower to judge others，and realize that some things are as they seem．

　　Are morning people born or made? In my case it was definitely made．In my early 20s, I rarely went to bed before midnight, and I would almost always get up late the next morning．

　　But after a while I couldn't ignore the high relationship between success and rising early．On those rare occasions where I did get up early, I noticed that my productivity was almost always higher．So I set out to become a habitual early riser．But whenever my alarm went off, my first thought was always to stop that noise and go back to sleep．Eventually some sleep research showed me that I was using the wrong strategy．

　　The most common wrong strategy is this：You assume that if you’re going to get up earlier, you'd better go to bed earlier．It sounds very reasonable, but will usually fail．

　　There are two main schools(流派)of thought on sleep patterns．One is that you should go to bed and get up at the same time every day．The second school says you should go to bed when you’re tired and get up when you naturally wake up．However, I have found both of them are wrong if you care about productivity．If you sleep at set hours, you'll sometimes go to bed when you aren't sleepy enough．You’re wasting time lying in bed awake and not being asleep．

　　If your sleep is based on what your body tells you, you'll probably be sleeping more than you need．Also, your mornings may be less predictable if you’re getting up at different times．

　　The solution for me has been to combine both methods．I go to bed when I'm sleepy and get up with an alarm clock at a fixed time．So I always get up at the same time(in my case 5 am), but I go to bed at different times every night － sometimes at 9：30pm, and other times at midnight．Most of the time I go to bed between 10-11 pm．

　　However, going to bed only when I'm sleepy, and getting up at a fixed time every morning is my way．If you want to become an early riser, you can try your own．

　　When we think about giving help to developing countries, we often think about giving money so that these countries can build schools and hospitals, buy food and medicine, or find clean water supplies．These seem to be the most important basic needs of the people we are trying to help．However, it's far from enough．Ladies and gentlemen, we've got to come up with some better ideas to help them．

　　I was very surprised, then, when I read about a plan to make cheap laptop computers for children in developing countries．A man called Nicholas Negroponte invented a cheap laptop computer, which can run without electricity．He decided to invent this computer after he visited a school in Cambodia．

　　The laptop which Mr．Negroponte has designed is a little different from the normal laptop computers you can buy in the shops．One difference is that it is covered in rubber so that it is very strong and won't be damaged easily．As an electricity supply can be a problem in developing countries, the computer also has a special handle so that children can wind the computer up to give it extra power when needed．

　　These special laptop computers will cost less than 100 US dollars and Mr．Negroponte wants to build as many as 15 million machines in the first year of production．The idea is that these computers will help the children's education as they will be able to access the Internet．These computers might not help the people in developing countries immediately, but by improving children's education they should help people to find their own solutions to their problems in the long term．

　　Another idea to help children in developing countries is to recycle old mobile phones so that they can be used again．In the UK, and, probably in many other countries too, millions of mobile phones are thrown away every year．The waste created by throwing away these old phones is very bad for the environment, so it seems to be an excellent idea to recycle them．In this way we will be able to achieve two important goals at the same time．We will reduce the waste we produce and help others．In other words, we will be able to 'kill two birds with one stone', and that is always a good thing．

　　Hi! Have you ever suddenly felt that someone you knew was in trouble － and was he? Have you ever dreamed something that came true later? Maybe you have ESP(超感觉知觉)．

　　ESP stands for Extrasensory Perception．It may be called a sixth sense．It seems to let people know about events before they happen, or events that are happening some distance away．

　　Here's an example．A woman was ironing clothes．Suddenly she screamed, "My father is dead! I saw him sitting in the chair! " Just then, a telegram came．The woman's father died of a heart attack．He died sitting in a chair．

　　There are thousands of stories like this one on record．Scientists are studying them to find out what's behind these strange mental messages．Here's another example-one of hundreds of dreams that have come true．

　　A man dreamed he was walking along a road when a horse and carriage came by．The driver said, “There's room for one more．”The man felt the driver seemed dead, so he ran away．The next day, when the man was getting on a crowded bus driver said, “There's room for one more．”

　　Then the man saw that the driver's face was the same face he had seen in the dream．He wouldn't get on the bus．As the bus drove off, it crashed and burst into flames．Everyone was killed!

　　Some people say stories like these are coincidences．Others, including some scientists, say that ESP is real．From studies of ESP, we may someday learn more about the human mind．

　　Chocolate is good for your heart, skin and brain．Usually, people think that chocolate is bad for their health．They describe chocolate as “something to die for” or say “death by chocolate”．Now they should bite their tongues! Evidence(证据)is showing that some kinds of chocolate are actually good for you in the following ways：

　　A happier heart

　　Scientists at Harvard University recently examined 136 studies on cocoa－the main ingredient in chocolate and found that it does seem to strengthen the heart．Studies have shown heart benefits from increased blood flow．These benefits are the result of cocoa's chemicals, which seem to prevent both cell damage and inflammation(炎症)．

　　Better blood pressure

　　If yours is high, chocolate may help．Jeffrey Blumberg from Tufts University recently found that people with high blood pressure who ate 3.5 ounces of dark chocolate per day for two weeks saw their blood pressure drop quickly．

　　Muscle magic

　　Chocolate milk may help you recover after a hard workout(锻炼)．In a small study at Indiana University, people who drank chocolate milk between workouts did better on a tiredness test than those who had some sports drinks．

　　Better for your skin．German researchers gave 24 women a half-cup of special cocoa every day．After three months, the women's skin was moister(滑润的)and smoother．The research shows that chocolate helps protect and increase blood flow to the skin, improving its appearance．

　　Brain gains

　　It sounds almost too good to be true, but research suggests that chocolate may improve your memory, attention span, reaction time, and problem-solving by increasing blood flow to the brain．

Teens' lives hit by economy

　　Some teenagers are crossing their dream colleges off their lists．Others are thinking of skipping(略过)their senior trips or reducing prom(毕业舞会)costs．Many are finding their work hours cut while their expenses rise．

　　So，who exactly is punishing them? Is it their parents，teachers or employers? No，it's the economy(经济状况)．

　　If you are like most teenagers，you probably don't understand what “recession”，“negative economic growth” and “subprime mortgage crisis(次贷危机)”actually mean．And you probably don't spend your days watching the ups and downs of the stock market．

　　It's safe to say that most teens don't know much about the economy except for one thing：it's bad．But just how exactly is the economy affecting teens?

　　“The single largest thing I have noticed is the recession's ability to affect my college choice，”said Heather Richars from Downey High School in California, US．“With the economic situation the way it is，I have thought less about going to a private or out-of-state university，and more about public schools in California，mainly because of the price of tuition，”said Richars．“I had been a fan of attending a private school up until this year．”

　　The economy cuts into other areas of teenagers' lives，too．

　　Joey Camarda, a student at Modest to High School in California, who works at an ice cream store, said, “Probably due to the economy, I have been getting less hours atmy job, and because of that, I am not getting enoughmoney to helppay for college．”

　　Tara Mooney，a senior at Beyer High School，has also begun to notice that money is tight．

　　“Things are getting expensive, ” she said．“When it comes to applying for colleges and wanting to go on senior trips，I have to pick and choose instead of doing it all．”

　　Recently I paid a visit to Harvard University, where there are top class scientists and professors and the best academic system in the world．

　　I was pretty shocked when I first stepped onto the campus．Well, it's not even really a campus．It's more like a district in a small town．

　　Harvard's main buildings are from the 18^th century．They look very old and simple．You might even say they’re a little shabby．They don't fit the modern idea of university at all．The buildings are surrounded by grass and trees, so I felt as if I had walked into a medieval castle．But when I looked across the street, busy shops and in-fashion students made me feel like I was in the 21^st century again．It creates a strong contrast(对照)and brings a special atmosphere to the school．

　　Our tour guide Gary took us around and told and told us, “You see this grass field in the center of the school? Here is where they host their graduation ceremony．They just set up tents and benches and have a very simple ceremony．Unbelievable! Who would think the most talented students just graduate on the lawn?”

　　I saw some students put a blanket on the grass and lie down to read a book．When I listened to the soft sound of pages turning, along with the chirping(鸟叫声)of the birds, I felt very calm．There was no competitive feeling at all．

　　Harvard has the world's first computer in its science center and there are hundreds of high-end computers too．Its religion and the literature departments are also among the best．It is the perfect mix of tradition and new technology．It makes Harvard a very attractive place to study in．

　　I hope one day I'll attend my dream school-Harvard．
