We often find that weekends and holidays feel so short while classes and work feel so long. Actually, though, we know that this is not true. But we still wonder where that strange feeling comes from.

    In fact, this is one of the ways that we're tricked by time, according to the website. All that S interesting. The website lists several wrong impressions (印象) we often have about time. Let's have a look.

    First of all, emotions affect (影响) our time-keeping abilities. Negative emotions (消极情绪). especially anxiety and boredom, make time seem longer because they make us concentrate (集中) more on the passage of time. However, when we are enjoying ourselves, we pay more attention to what we are doing and are likely to lose track of (失去对……的意识) time.

    Here is another example. In 2007, a group of scientists carried out a test. In the test, people fell 50 meters into a safety net and were then asked about their experience. Although the experience took shorter than 3 seconds, the people thought it was much longer than it actually was.

    This is because of the way our bodies reply to danger, according to the scientists. Our bodies produce a chemical called adrenaline (肾上腺素) when we are faced with danger. It allows us to concentrate better so that we can stay alive. As a result, we are able to remember far more details (细节) over a short period of time, which makes it seem like time is going more slowly.

    Another situation when we make mistakes about time is when we take afternoon naps (午觉). Have you ever had trouble telling what time it is after a long nap? That's because the best amount of time for a nap is 20 minutes. After 20 minutes, you enter a new stage of sleep called slow-wave sleep. If you wake up mid-way in this stage, it will take a while before you can correctly perceive (感知) time again.

    Yes, time can be mysterious (神秘的) and there is no way to control it. So, perhaps the best thing to do is to make good use of every minute.

    In traditional Chinese medicine, food is divided (划分) into two types; hot and cold. Both kinds of food affect (影响) your body {#blank#}1{#/blank#} different ways, So, having 57. {#blank#}2{#/blank#} balanced diet is safe and {#blank#}3{#/blank#} (health) for your body.

    Some examples of hot food {#blank#}4{#/blank#} (be) berries, mutton, and ginger (生姜) . If you eat too much of them, {#blank#}5{#/blank#} (certainly) things might happen to your body. You may start to sweat a lot and feel pain in your back, or even grow gray hair! If these things happen to you, you should avoid (避免) spicy food, coffee, or sugar.

    On  {#blank#}6{#/blank#} other hand, too much cold food like tomatoes and potatoes can also cause problems. It may make your hands and  {#blank#}7{#/blank#} (foot) cold. It also makes your body temperature lower.

    Besides what we eat, {#blank#}8{#/blank#} we eat is also important. You should always sit down and chew (咀嚼) carefully. Don't make {#blank#}9{#/blank#} (you) busy with other things, such as watching TV or {#blank#}10{#/blank#} (read) a newspaper. Finally, it's best to eat three meals a day at regular times.

There are many wetlands (湿地) in China ‒ and some of them have become the world's important wetlands. The Chinese Yellow Sea Wetlands are {#blank#}1{#/blank#} them. They are in Yancheng, Jiangsu Province. They are {#blank#}2{#/blank#} to many different kinds of animals. The world's {#blank#}3{#/blank#} Milu deer nature reserve (自然保护区) is on these wetlands. More than 700 Milu deer live there. There are not many red-crowned cranes (丹顶鹤) {#blank#}4{#/blank#} in the world, but every winter, you can see some in the red-crowned crane nature reserve in the Yellow Sea Wetlands.

    The {#blank#}5{#/blank#} in the wetlands is neither too high nor too low. There is  {#blank#}6{#/blank#} rain and sunshine, too. They are a good place for wildlife. But offering food and shelter for special kinds of animals is not the  {#blank#}7{#/blank#} reason we need to protect wetlands. Wetlands are important {#blank#}8{#/blank#} they also prevent floods. But some people want to {#blank#}9{#/blank#} the wetlands to make more space for farms and less space for wildlife.

    More people are beginning to realize the {#blank#}10{#/blank#} of wetlands and wildlife. Every year, on Feb 2, many activities are held to teach people about the wetlands.

    In England, people often talk about the weather because you can experience four seasons in one day. In the morning the weather is warm just like in spring. An hour 1 black clouds come, and then it rains hard. The weather gets 2 cold. In the late afternoon the sky will be clear, the sun will begin to shine and it will be summer at this time of a day.

    In England, you can also have summer in winter, 3 have winter in summer. So in 4 you can swim sometimes, and in summer sometimes you should wear warm clothes.

    When you go to England, you will see some English people take umbrellas or rain-coats with them on the 5 morning, but you shouldn't laugh at them. If you don't take an umbrella or a raincoat, you will regret later in the day.

    We have to be fit, no matter (不管) what age we are. It's very important for kids. That's w{#blank#}1{#/blank#} they have P.E. class.

    In Britain students have two hours of P.E. each week. P.E. includes sit-ups, press-ups (俯卧撑) and skipping rope.

    Students also p{#blank#}2{#/blank#}football, basketball and cross-country running. In summer kids run and do the high and long jumps.

    When I was at school my favourite was trampoline(蹦床). Jumping high into the air always made me excited. But you need to be c{#blank#}3{#/blank#}. Sometimes you don't land where you planned!

    When you get your report card there will be a grade for P.E.. Your parents will see how good you are a{#blank#}4{#/blank#} push-ups, as well as maths. But the grade for P.E. doesn't affect (影响) your chances of g{#blank#}5{#/blank#} into a good school.

    Americans think much about time. From childhood they learn to {#blank#}1{#/blank#} time. They are taught to be on time to go to school, to work and to do everything. When they are having a good time, they time goes easily. When a person is dying, they say he is living on borrowed time.

    Time is money. Time is knowledge. Time is {#blank#}2{#/blank#}in America. A working American has to work hard for eight hours a day or forty hours a week. This is the working time. In his free time, he also works hard for more money. Even on Saturday and Sunday he also works hard as {#blank#}3{#/blank#}. In the street you can hardly see a man walking{#blank#}4{#/blank#}. They walk very fast. In fact, they are running.

    They love time because time can bring them money and lots of things.{#blank#}5{#/blank#}sometimes they also hate time, because they feel they have become servants of the clock.
