{#blank#}1{#/blank#} it was autumn, the snow was already beginning to fall in Tibet. Our legs were so heavy and cold that {#blank#}2{#/blank#} felt like big blocks of ice. Have you ever seen snowmen ride bicycles? That's what we looked like! Along the way children who {#blank#}3{#/blank#} (dress) in long wool coats stopped to look at us. In the late afternoon we found it was so cold that our water bottles froze. However, the lakes {#blank#}4{#/blank#} (shine) like glass in the setting sun and looked wonderful. Wang Wei rode in front of me as usual. She was {#blank#}5{#/blank#} high spirit and I knew I didn't need to encourage her. To climb the mountains was hard work but as we  looked around us, we were surprised by the view. We seemed to be able to see for miles, and we were {#blank#}6{#/blank#} high that we found ourselves cycling through clouds. After {#blank#}7{#/blank#} while, we began going down the mountains. It was great fun especially as it slowly became much {#blank#}8{#/blank#}(warm). At the foot of the mountains, colorful butterflies flew around us and we saw many sheep {#blank#}9{#/blank#}(eat) green grass. Then we had to  change our caps, gloves and trousers {#blank#}10{#/blank#} T-shirts and shorts.

There has been a recent trend in the food service industry toward lower fat content and less salt．This trend，which was started by the medical community（医学界）{#blank#}1{#/blank#}a method of fighting heart disease，has had some unintended side{#blank#}2{#/blank#}（effect） such as overweight and heart disease—the very thing the medical community was trying to fight．

    Fat and salt are very important parts of a diet．They are required{#blank#}3{#/blank#}（process） the food that we eat，to recover from injury and for several other bodily functions．When fat and salt {#blank#}4{#/blank#}（remove） from food，the food tastes as if it is missing something．As {#blank#}5{#/blank#}result，people will eat more food to try to make up for that something missing．Even {#blank#}6{#/blank#}（ bad），the amount of fast food that people eat goes up．Fast food{#blank#}7{#/blank#}（ be） full of fat and salt； by {#blank#}8{#/blank#}（ eat） more fast food people will get more salt and fat than they need in their diet．

    Having enough fat and salt in your meals will reduce the urge to snack（吃点心） between meals and will improve the taste of your food．However，be {#blank#}9{#/blank#}（ care） not to go to extremes．Like anything，it is possible to have too much of both，{#blank#}10{#/blank#} is not good for the health．

    I wonder if it is because I haven't been able to be outdoors for so long {#blank#}1{#/blank#}I have grown so crazy about everything to do with nature. I can well remember that there was a time{#blank#}2{#/blank#}a deep blue sky, the song of the birds, moonlight and flowers could never have {#blank#}3{#/blank#}(keep) me spellbound. That has changed since I came here. For example, one evening when it was so warm, I stayed {#blank#}4{#/blank#} (wake) on purpose until half past eleven in order to have a good look at the moon by myself. But as the moon gave far too much light, I didn't dare open{#blank#}5{#/blank#}window. Another time five {#blank#}6{#/blank#}(month) ago, I happened {#blank#}7{#/blank#}be upstairs until the window had to {#blank#}8{#/blank#} (shut). The dark, rainy evening, the wind, the thundering clouds held me {#blank#}9{#/blank#}(entire) in its power; it was the first time in a year and a half that I{#blank#}10{#/blank#}(see) the night face to face...

    Teenagers have long been told that being active and {#blank#}1{#/blank#}(take) part in sports is good for their health. But new research suggests that too much sport for teenagers could negatively affect their well-being just as much as too {#blank#}2{#/blank#} sport.

    The US Department of Health and Human Services suggests that young people {#blank#}3{#/blank#}(age) between 6 and 17 work{#blank#}4{#/blank#}at least 60 minutes a day, 7 hours a week. But researchers from Switzerland say their study suggests that 14 hours of physical activity a week is best for promoting good health in teenagers. However, more than 14 hours {#blank#}5{#/blank#} (appear) to be harmful to their health. To reach their findings, they had 1,245 teenagers {#blank#}6{#/blank#}(survey) in their research.

    All participants (参与者) were required to answer questions about height and weight, sports practice, sports {#blank#}7{#/blank#} (injure) and well-being. Their well-being was measured using the Word Health Organization (WHO) Well-being Index, {#blank#}8{#/blank#} provides scores between 0 and 25. Of the participants, 50.4% were male. Almost 9% of these males were overweight. The overall {#blank#}9{#/blank#}well-being score for all participants was 17.

    The researchers divided sports participants into low, average, {#blank#}10{#/blank#}, and very high. The researchers found that participation in the low and very high activity groups were more likely {#blank#}11{#/blank#} (have) well-being scores below 13, compared with participants in the average group. The researchers found that the highest well-being scores were {#blank#}12{#/blank#} a by participants who carried out around 14 hours of physical activity a week, but beyond 14 hours resulted {#blank#}13{#/blank#} lower well-being scores.

    The researchers suggest that doctors {#blank#}14{#/blank#} care for teenagers should check their level of sports practice. Teenagers {#blank#}15{#/blank#} (probable) need a supportive and closer follow-up of their health and well-being.

    Nowadays more and more people like to travel, {#blank#}1{#/blank#} (especial) when vacations come.A great number of people rush out of their homes or companies to {#blank#}2{#/blank#} (travel) spots. They either drive or take a bus, a train, a ship {#blank#}3{#/blank#} so on. Some even ride bikes.

    However, there {#blank#}4{#/blank#} (be) another way of travelling—poorism. People have a tour in {#blank#}5{#/blank#} poorest areas of the worlds Some people may take a one-day poorest tour, and some even pay to stay in very poor neighborhoods {#blank#}6{#/blank#} (experience) the lowest living standards in the worlds Poorism tours take place around the world, and not just in the third world {#blank#}7{#/blank#} (country).You can, for instance, tour New York neighborhoods in the Bronx. Such tours can take people into the heart of poor areas. These tours may awaken people to pay {#blank#}8{#/blank#} (much) attention to long-standing poverty, or the effects of war.

    Some think that tours in the poor areas can raise social care. And the money from the tour can {#blank#}9{#/blank#} (donate) to help the people {#blank#}10{#/blank#} live there.
