Clothes are traditionally made of natural materials, such as cotton, leather and wool. They are all from plants or animals, but that doesn't mean they're friendly to the earth. For example, farmers have to use a lot of chemicals to grow cotton plants.

    Scientists are now looking for new ways to make clothing materials. They hope the new materials are both comfortable and good for the earth. Scientists have worked out how to make materials out of cornhusks (谷壳), chicken feathers and rice straws.

    "They used to be useless things. We always have a problem of how to deal with them," Yang, a scientist says. "Now, we can turn them into beautiful materials. Chicken feathers are better than other things. They have small air pockets like honeycombs. That means it will be very warm if you use them to make a jacket or sweater, and I think more and more people will like to buy these kinds of clothes."

    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.

There are many festival s around the world. Dads have Father's Day. Moms have Mother's Day. But do our grandparents have a1 ? Yes, they do.

The Double Nint h Festival is a special day 2 old people in China. The festival is on the3 day of lunar September. On this day, people4 love and respect(尊敬) to their grandparents.

Respecting old people is a tradition in China.5 an old person walks into a room, everyone should stand up. Also, people are introduced from the 6 to the youngest. If we want to give something to an old person, two hands are used. The old usually don't have to buy tickets for buses and young people always 7 their seats to old people on a crowded subway or bus.

However, in western countries, old people have 8 lifestyles from those in China. They don't often live with their children, they live 9 . They don't want to get help from others. They even don't want to be offered seats. Westerners still respect old people. For holidays, families usually 10 at the grandparents homes. A great smile and a warm hug are enough for grown children to show their respect.
