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.

We can find stone everywhere. Stone is usually very hard, {#blank#}1{#/blank#} it can be soft. Stones have many uses.

In ancient times, people carved (雕刻) small persons or animals out of soft stones which could be carried along with. While in some {#blank#}2{#/blank#} countries, statues (雕塑) are carved from hard stones and they do not change easily. In summer, the hot sun {#blank#}3{#/blank#} on these statues and in winter the snow falls on them, but they still remain beautiful.

Stone is strong and long-lasting. So, it is good enough for different houses. Houses built of stone do not catch fire as easily as ones made of wood. Some stones are colored, so they make the {#blank#}4{#/blank#} look wonderful. People can also get a fire {#blank#}5{#/blank#}stones to make food.
