Most students, when asked about their best graduation(毕业) gift, would probably reply, “ A car”, or “Money for a house”. Cai Kaiyuan, 21, made a difference choice. As a graduation gift to himself, he decided to work as a volunteer teacher in a distant village in Tibet.

    Cai, a student at Huan Railway Professional Technology College, at first planned to cycle from Sichuan to Tibet. It turned out cycling on a plateau(高原) was quite difficult. And it has kept changing his opinion on life. Cai's hands even became painful while cycling up a 5008-meter-high mountain, where temperatures often dropped to 18 below zero. At night, the ice covered the road and he fell off his bike three times. Little oxygen made him feel sick and weak. “At the most serious moment, I felt that was on the line,” said Cai.

    However, he also gained something unexpected. At Ya' an, a city in Sichuan, he met a group of tourists who are also university students. A girl called Wu Ling told him that she planned to work as a in a primary school in Tibet after her journey. He was impressed by the idea as she looked weak.

    It was not until he reached a family-run hotel in Shigatse that Cai's spirits began to rise. The hotel manager's two daughters enjoyed talking with him. The kids asked about his experiences on his trip, and showed him the beautiful local lakes. “They told me that they always liked to talk to guests, as they wanted to improve their Mandarin,” he said, “Their parents and many locals can only speak Tibetan.”

    Cai was moved by the girls' story. Their situation is worse and the local people have little chance to learn Mandarin because the schools are short of teacher. “1 want to do something to improve the situation for kids like them,” said Cai. His parents finally gave their agreement and his teachers also supported him.

    When I was 12, all I wanted was a signet(图章)ring. They were the “in” thing and it seemed every girl except me had one. On my 13th birthday, my Mum gave me a signet ring with my initials(姓名首字母) carved into it. I was in heaven.

    What made it even more special was that it was about the only thing that wasn't being “replaced”. We'd been burnt out in fires that swept through our area earlier that year and had lost everything—so most of the “new” stuff(东 西)we got was rally just to replace what we'd lost. But not my ring. My ring was new.

    Then, only one month later, I lost it. I took if off before bed and it was missing in the morning. I was sad and searched everywhere for it. But it seemed to have disappeared. Eventually, I gave up and stopped looking for it. And two years later, we sold the house and moved away.

    Years passed, and a couple of moves later, I was visiting my parents' when Mum told me that she had something for me. It wasn't my birthday, nor was it Easter or Christmas or any other gift-giving occasion. Mum noticed my questioning look. “ You'll recognize this one.,” she said smiling.

    Then she handed me a small ring box. I took it from her and opened it to find my beautiful signet ring inside. The family who had bought our house 13 years earlier had recently decided to do some redecorations, which included replacing the carpets. When they pulled the carpet up in my old bedroom, they found the ring. As it had my initials carved into it. They realized who owned the ring. They'd had it professionally cleaned up by a jeweler before sending it to my mother. And it still fits me.

    As an expert on the science of sleep and sleep disorders, Michael Twery believes “People have good understanding about the necessity of sleeping 7-8 hours in bed. But they undervalue the function of napping in day.”

    For example, many Americans do nap. But one-third of adults in the US are also frequently tired. Someone who naps as a way of paying off a sleep debt may not experience the same improvements from napping as a healthy, well-rested person would.

    Also, many people may not want to admit that they take a nap. That only children, the very old, sick or lazy people nap is a common opinion. In fact, Americans sometimes do very strange things. For those who claim they only sleep five hours a night, they may think they are somehow stronger than the average human—superhuman, if you will.

    Luckily, many offices now offer napping rooms in many U. S. cities. While resting in the middle of the work day may seem like a luxury to Americans, napping is very much part of a normal, everyday life in other parts of the world.

China, generally speaking, is a land of nappers. Researchers recently looked at information provided by nearly 3, 000 Chinese adults, aged 65 years or older. Based on their answers, researchers put them into four groups: non-nappers (0 minutes), short nappers (less than 30 minutes), moderate nappers (30-90minutes), and extended nappers (more than 90 minutes).

    The study found that the hour-long nappers did better on the tests than those who napped for shorter and longer periods. Keep in mind, however, that these are the findings for those over the age of 65.

    Michael Twery notes that an hour long nap may be too long for young, healthy adults. “Currently, 30 minutes is enough to remove the pressure to sleep and will help us feel more awake. If we nap longer, we will get trapped into sleep inertia—a very deep sleep period.”

    Do you love holidays but hate the fact that you put on weight (增加体重) after the holidays? You are not alone.

    Holidays are happy days with pleasure and delicious foods. Many people, however, are worried about the weight that comes along with these delicious foods.

    With proper planning, it is possible to control your weight. The idea is to enjoy the holidays but not to eat too much. You don't have to turn away from the foods that you enjoy. The following suggestions may help you.

    Do not miss meals. Before yon leave home for a feast(宴会), have a small, low-fat snack. This may help to keep you from getting too excited before delicious foods.

    Begin with clear soup, fruit or vegetables.

    A large glass of water before you eat may help you feel full.

    Use a small plate; a large plate will encourage you to have more than enough.

    Better not have high-fat foods. Dishes that look oily or creamy have much fat in them.

    Choose lean（瘦的） meat. Fill your plate with salad and green vegetables.

    If you have a sweet tooth, try mints (薄荷) and fruits. They don't have fat content as cream and chocolate.

    Don't let exercise take a break during the holidays. A 20-minute walk after a meal can help burn off excess calories (多余的热量).

    Three years ago I worked for a few weeks as a doctor in a new dental clinic(牙科诊所）at Victor Harbor to the south of Adelaide and an hour further away than my usual workplace. My first day there was a driving to a new clinic and getting used to the clinical environment.

    As it was all new to me, I took off my rings: my wedding ring, and one that was an anniversary(周年纪念日)gift from my husband. I put them in a tissue(纸巾)and placed them beside my computer. During my lunch break, I noticed the tissue and thought that it did not look very clean and threw it into the rubbish bin. I went about my work and my day went well; I met new patients and felt that I had been productive

    Driving home at the end of the day, just moments before I reach that were missing. I felt the heat in my body rise, my cheeks(脸颊)burning red. I felt sick to my stomach.

    I spat an hour or so making calls, trying to find my rings. The first people I called were and clinical leader and they gave me a few phone numbers for cleaners I got in touch with already who managed the leaning services for the clinic, and she told me that the bins had already been collected.

    I knew nothing could be done now. I had lost my rings. Bu after two or so hours, I received the most amazing phone cal. The cleaner had gone through the bins and found my rings! I was so thankful to her, someone who had taken the trouble to go through the bins-which is not a pleasant task-to find my priceless rings.

    I worked at that clinic the following day, so I bought chocolates to thank this wonderful person. Unfortunately I did not get to meet her as she was not at work that day.
