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.

    Here I want to tell you some informationabout water.

    Water covers most of our planet. People canfind it in oceans, lakes and rivers, and under the ground. Water moves in theenvironment by evaporation, condensation, and precipitation. The warm Sun helpswater change into vapour and rise up into the sky. It is evaporation. Thevapour in the air forms clouds in the sky. It is condensation. When the cloudsget heavy enough, the water falls back to the ground as rain or snow. This isprecipitation.

    Ocean water has too much salt in it. Muchof the water travels far over the land. When it travels over the land, thewater picks up salt from the rocks and soil. About 97.5% of the Earth's wateris salty water. It is expensive to take salt out of the water.

    All people need clean water. They need itfor drinking, for cooking, and for bathing. Some people in a village in SouthAmerica did not have clean water. Their water was full of oil and dirty things.People there got sick when they drank the water. Other people heard about theproblem. They sent empty water tanks (储水池) tothe village. Rainwater fell into the tanks. Now the people in that village havethe clean water.

School PE Club is going to have some sports classes for the new term. Let's have a look. 

When I was a student in France，a local friend invited me to have lunch at her home. During the meal，I found all her family had their hands on the table，except me. Later I learned that it's impolite to put your hands under the table.

When I was a student in the UK，I went to a pub with two local friends. We all had a drink and I drank mine quickly. My friends still had half﹣full glasses so I bought another drink，just for myself. My friends said，"You can't do that. When in a pub in the UK，you should buy drinks for you and your friends. "I was so embarrassed（尴尬的）. 

—Henry

I spent a year studying in Germany. I was shocked the first time I went to a lecture（讲座）. At the end of the lecture，all the students started knocking on their desks. How strange!A student told me that in Germany，students don't clap their hands（拍手）to show they like something. They knock on their desks instead.

I love making birthday cards. One day，when I was a student in South Korea，I made a birthday card for a local friend. But when I gave the card to her，she cried，"My name is written in red ink（墨水）!"She said in South Korea，a name written in red ink means that the person has died.

When you are busy or stressed, don't forget your{#blank#}1{#/blank#} , such as listening to music, reading and playing ball games. If eating makes you feel {#blank#}2{#/blank#}, you can go to your favorite restaurant {#blank#}3{#/blank#}a delicious meal. 

Parents may not think that it is {#blank#}4{#/blank#}to watch TV. {#blank#}5{#/blank#}, if you are worried about your English and don't know how{#blank#}6{#/blank#} it, why not watch some English TV{#blank#}7{#/blank#}? If you're feeling bad about your weight and don't know {#blank#}8{#/blank#}to do, why not go walking or jogging?

{#blank#}9{#/blank#}, trying to keep your worries to yourself can make them worse. I like to {#blank#}10{#/blank#}my problems with my friends. They always give me important advice. If you don't know who to talk to, you can always write to me. You're {#blank#}11{#/blank#}alone. 

Whether it's changing jobs, taking care of a sick parent, or moving to a new place, disruptions(混乱) in life can make it hard to maintain moment-by-moment focus and well-being (健康). Long-term goals remain important, but long-term focus can be hard. Daily or weekly habits supporting your long-term goals can keep you on track even when it's hard to think ahead.

 The first is personal reflection(反思). This can mean keeping diaries, documenting the funny things our friends say, and recording what we are thankful for a few times per week. {#blank#}2{#/blank#}

 Second, we need time for professional reflection. For example, you may sit down on a Sunday night and write down the most important to-dos in the coming week. {#blank#}3{#/blank#}Instead, it directs your focus to what's most important. Simple, daily or weekly reflection case make a meaningful difference in productivity and focus.

A third area is building and maintaining relationships. It's important to manage our relationships well. For us, right now, the primary relationships are with our parents and teachers. {#blank#}4{#/blank#}These sound like small things, but they matter a lot.

 Finally, we all need to form good habits that encourage physical and mental health. Studies show that people who get at least two days of exercise per week are happier. {#blank#}5{#/blank#}
