Sports can help you keep fit and get close to nature.However,whether you are on the mountains,in the waves or on the grassland,you should realize that the sport you choose might have great influence on the environment.

Some sports are resource-?hungry.Golf,as you may know,eats up not only large areas of countryside,but also lots of water.Besides,huge amounts of energy are used to keep its courses(球场)in good condition.This causes major environmental changes.For example,in the dry places of Portugal and Spain,golf is often the main reason for serious water shortages(短缺)in some local areas.

There are also many environment-?friendly sports.Walking is one of sports that you could take up today.You don't need any special equipment except a good pair of shoes,and you don't have to worry about resources and your purse.Simple and free,walking can also help you stay healthy.If you walk regularly,it will be good for your heart.Experts say that 20 minutes of speed walking daily can make you feel less anxious,sleep well and keep thin.

Whatever sport you take up,you can make it greener by using environment? friendly equipment and buying products made from recycled materials.But the final goal should be “green gyms”.They are better replacements(替代品)for traditional health clubs and modern sports centres.Members of green gyms play sports outdoors,in the countryside or other open spaces.There is no special requirement for you to start your membership(会员身份).And best of all,it's free.

Mr. Luo is a teacher from Xi’an. He asked his students to hand in their homework through a QR code (二维码). “We spent an hour or two in class learning how to generate the codes, and in the end everything gets easier,” said Luo “When students finish the homework, they keep it on WeChat. Then, each student makes his own QR code and gives it to me. So I can check their work everywhere using my computer or telephone.”

The QR codes can be sent to Mr. Luo by e-mail, QQ and WeChat. When Luo scans (扫描) his students’ QR codes, their homework appears on his phone. He finds that their homework becomes more creative, with many pictures, music and even videos.

Luo’s students like the new way and think it is interesting. “We are living in the information age. Many students like to work with computers, which makes learning more fun.” said Tingting, a student of Luo’s.

“The paper is not easy to keep, but the code is easy to keep and share,” Luo said. “It is worth trying to use new technology in education. Education itself is a kind of creation. I don’t want my students to fall behind the times.”

However, some parents are worried. They are afraid that their children will spend too much time on computers and endless time communicating with teachers. But in fact, it’s unnecessary. Students still need to look up information in books and write it down when they do their homework. They only use the code when they hand in their work, which doesn’t take them too much time. Also for teachers, it allows them to check the students’ work at any time. And it’s also an easy way to share homework with other students.

The shock of the earthquake in Pakistan has brought another shock: the rise of a mysterious island, coming out from the water.

In the aftershock of the earthquake, people living in Grabian Sea and saw a mountain-like shape coming out of the water. “It looked like a huge whale,” Bahram Baloch, a local reporter, told the BBC. “Lots of people gathered to watch it. ”

So what happened? The force of the earthquake was so strong that it moved the sea floor, releasing gas(释放气体). This gas pushed the seabed, mostly rock and sand, out of the water. This was how the mud volcano (泥火山) was formed. The island which is about 20 meters high, 30 meters long and 90 meters wide is actually the top of the mud volcano.

Is it safe? Although people have visited this new island, scientists have found dangerous gas coming from the newly formed island. “It will catch fire, when a match was lit,” said Mohammad Danish, a scientist, to Universe Today.

The mud volcano is strange because mud volcanoes seldom appeared in an area where people often live, and not far out in the sea. It is a special one. However, it’s not expected to last very long. Most of these mud volcanoes are swept back under the sea within one year.
