Life in the future will be different from life today.

    The population(人口) is growing fast. There will be more people in the world and most of them will live longer.

    Computer will be much smaller and more useful, and there will be at least one in each home. And computer science will be one of the most important subjects in school then. 

    People will work fewer hours than they do now, and they will have more free time for sports, watching TV and travel.

    Our food will be different, too. More land(土地) will be used for building new towns and houses for people. So there will be less land for cows and sheep, and meat will be more expensive. Maybe no one will eat it one day. They will eat more fruits and vegetables. 

    Work in the future will also be different. Robots will do dangerous and hard work. Because of this, many people will have no jobs to do. This will be a big problem in the future.

    Do you know the way of using wind power to make electricity? There are many advantages({优点) of using wind to make electricity. Here're some of them.

    First, it may be one of the cheapest ways to make electricity. Second, it can make and store hydrogen gas. The most important one is that it won't pollute the environment. Besides, the wind power can be reusable.

    But large wind farms might kill birds too, because birds always fly into the wind turbine(风力涡轮机). Scientists are looking for ways to stop it.

    Experts said that by the middle of the 21st century, wind power could supply more than 10% of the world's electricity. Wind really helps us a lot.

Can knots be a form of art? It is in China. It is used for decoration (装饰) on clothing or to hang on a wall. Skilled knot artists make knots that you might see sold in stores that you can take back with you. 

What Is a Chinese Knot?

A Chinese knot is a knot that is tied and woven (编织) from a single length of rope to be different shapes. Most knots have two cords (粗线) entering the knot from the top and two leaving from the bottom. Each kind of knot is named after its shape or the symbolic meaning that it carries.

Knot artists can use different colors, but they prefer deep red ones. The color red means good luck in China.

At first, people may have made them to record information before people started to write. One hundred thousand year old tools have been discovered that were probably used to tie and untie knots. 

It is known that they were used for artistic decoration and to express thoughts and feelings in the Tang Dynasty (618—907). The traditional art form was carried on by people as part of their culture.

Ancient and Modern Use of Artistic Knots

Even today, Chinese knots are rich in symbolic meaning, and they hold value when given as gifts or passed down through families. For example, in ancient times and even now, lovers may give a knot as a symbol of their love. The "true love knot" and the "double happiness knot" are given or used at weddings to express love and growing old together. 

Along with being symbolic gifts or messages, knots are still used if people wear traditional Chinese clothing. They are used as jewelry such as earrings and necklaces.

I am a dance teacher. I can feel strongly how important talent and hard work are for students. 

In fact，not everyone1 dancing when they came to this world. For example，some my students just spend two or three months dancing well. But other students need to learn2 . Many of my students learn dancing3 because they are talented. But talent does always bring a good4 . Even though dancing seems easy to a student，he or she sometimes finds it5 and gives up. And talented students sometimes find other things more interesting so they give up，too. 

However，some of my students are not talented. So I teach them again and again，and they6 very hard. But it just does not work for these students and they still can't dance7 . In my opinion，you don't need to do everything well. If you really don't have any talent8 something the best way is to give up. Then you can9 what you're truly interested in，and put all your heart into it. 

All in all，both talent and hard work play important10 in life. If you want to do the best，you need to find your talents and work as hard as you can. Don't give up halfway.
