    Thousands of years ago,in the south of ancient China,there lived Shennong,a man who had an ox head and human body.Seeing that local people were suffering from disease,he built ladders and houses on a high mountain to store hundreds of medical plants.To remember him,people named the place shennongjia.

    The legend(传说）makes Shennongjia in Hubei an inciting place for tourists.Traveling there is a unique experience,as you can see sceneries of the four seasons from different altitudes(海拔）.“When the bottom of the mountain is summer,the top is spring and while the foothill is autumn,the top is covered with ice,”local people say of the special climate of Shennongjia.

    Shennongjia is also home to 5,000 species of animals and plants.Many animals in danger live there,such as the golden monkey,the clouded leopard and the Asian black bear.

    One interesting and mysterious(奇妙的）thing about Shennongjia is its legend of wild men.Some people once claimed that they saw big prints or big-foot creatures.Yet so far,scientists haven't proved it is true and some say they are just bears.

    The beautiful place has recently received a new title.On July 17,2016,Shennongjia Forestry District was added to United Nations World Heritage list as a natural site.Chins now has 50 world heritage sites(遗址），second only to Italy in the world.

    Every school day, we use schoolbags to carry all of our things to school. They are a big part of our lives. But have you ever thought about the history of the schoolbag?

    In the Han Dynasty (汉朝), students in old-style private schools used bamboo boxes to carry books to school. People consider the bamboo boxes to be the earliest schoolbags. They were usually two or three layers (层) in the box. Kids put different things like books, brushes, ink stones (砚) and paper in the boxes.

    Hundreds of years later, people developed a new kind of schoolbag called the budai, or the "hip-pocket". The budai was lighter than the bamboo box. With the founding (成立) of the People's Republic of China, military rucksacks (军用帆布包) became popular. Many people carried them when they were in school. Ask your grandparents or parents about these bags. Maybe they can tell you about their experiences of carrying them when they were in school.

    A new style of schoolbags has appeared in recent years. Many of them have colorful and fashionable designs (时尚的设计) on them, such as pictures of cartoons or pop stars. And they are more comfortable to use. Some students pull wheeled bags filled with heavy textbooks and others carry backpacks.

    Schoolbags are still changing. Can you imagine what future schoolbags will be like?

    Sometimes it seems that time is flying. Perhaps it doesn't need to feel this way. Our experience of time can be possibly changed. By understanding the psychological (心理学的) processes behind our different experiences of time, we might be able to slow down time a little.

    One basic law of psychological time is that time seems to slow down when we're exposed (接触) to new environments and experiences. The law is caused by the relationship between our experience of time and the amount of information our minds process. The more information our minds take in, the slower time seems to pass.

    It follows, then, that we have different experiences of time in different situations. In some situations, our life is full of new experiences. Our minds process a lot of information and time seems to slow down. In other situations, we have fewer new experiences and the world around us becomes more and more familiar (熟悉的). We become insensitive to our experience, which means we process less information, and time seems to speed up.

    How can we slow down time? Here are two suggestions.

    Firstly, since we know that familiarity makes time pass faster, we can expose ourselves to as many new experiences as possible. We can give ourselves new challenges, meet new people, and expose our minds to new information, hobbies and skills. This will increase the amount of information our minds process and expand (增加) our experience of time.

    Secondly, and perhaps most effectively, we can give our whole attention to an experience-to what we are seeing, feeling, tasting, smelling or hearing. This means living through our senses rather than through our thoughts. For example, on the way home, focus your attention outside of yourself, instead of thinking about the problems you have to deal with. Look at the sky, or at the buildings you pass, traveling among them. This open attitude to your experiences helps take in more information and also has a time-expanding effect.

    To a certain degree, we can understand and control our experience of time passing. It's possible for us to slow down time by expanding our experience of time.
