    Sixty years ago，human beings first reached the top of Mount Qomolangma， known as Mount Everest in the West. But the increase in climbers is turning the world's highest mountain into the “world's highest junkyard(垃圾场)”.

    Every year， more than 700 climbers spend nearly two months on Mount Qomolangma. They have left human waste and all kinds of rubbish， including oxygen bottles， broken tents， and plastic bags， according to Ang Tshering Sherpa， chief of the Nepal Mountaineering Association.

    “The waste has become a health danger to people in the area since they depend on water from rivers fed by the melting glaciers(融化的冰川)，” Sherpa said.

    More and more people have realized the danger that Mount Qomolangma is facing and they are now taking active actions. To deal with the problem， Nepal has supported a special team of explorers and volunteers to clean the mountain since 2008. So far they have brought down 15，000kg of rubbish. Nepal also started to ask each climber to bring down 8 kg of rubbish in 2014.

    On the Chinese side of the mountain， Tibet(西藏) will collect a cleaning fee of $100-200 (620-1240 yuan) per climber starting from this year. A program named “Mount Qomolangma Action at the Third Pole of the Earth” also started in 2004 to clear up the mountain.

    Hopefully， human beings will finally solve the problem， just as they found the way up the mountain successfully.

    The days of having to carry a phone charger(充电器) everywhere could soon be over. Researchers from America have made great progress in getting energy from human motion(运动). They say smartphones could get enough power just by the motion of fingers on the screen.

    The low-cost device(装置) has already been tested in an American university. Scientists successfully showed an LED touch screen, a total of 20 LED lights and a keyboard, all with a simple touching or pressing motion and without the help of a battery.

    "What I predicted is the possibility of not having to charge your smartphone for a whole week, for example, because that energy will be produced by your motion," said one of the researchers.

    The completed device is as thin as a piece of paper. Electrical energy is created when you press it. The device used to power the LED lights is the size of a hand while the device used to power the touch screen is as small as a finger.

    The device will become more powerful when folded. Each time you fold it, the energy you create will be doubled. You can start with a large device, but when you fold it once, and again, and again. It's now much smaller, but it has more energy. It may be small enough to put in a specially made heel(脚后跟) of your shoe so it can create power each time your heel knocks the ground. The researchers are also developing technology that would send the power produced from the heel strike to an earphone.

    It is a cold and dry winter morning. When you wake up, you feel that your throat hurts. You begin to sneeze and later you may cough. You must have a cold！Wait a moment. Could it just be a common cold or the flu(流感)that's been going around？

    A cold gives you a runny nose and cough. But it's usually easy to deal with. Some people take medicine while others drink herbal tea or chicken soup. Usually you feel better after a week.

    On the other hand, the flu can be much more dangerous. It usually gives you fever. Sometimes it can cause death. According to an American magazine, the worst flu killed about 50 million people from 1918 to 1919.

    Don't worry. If you get a flu vaccine(疫苗), it can stop you from getting the virus(病毒).Flu vaccines work by giving the body a small number of flu viruses. This causes your body to develop antibodies(抗体). So next time you get the flu, the antibodies will help you.

    The flu virus changes every few years. Therefore, there are so many types of flu, such as HlN1 and H5N1.The antibodies for one type of flu can't help us against all types of flu. That's why we need to get the vaccine every year.

    However, good healthy habits may also help stop you developing a cold or flu. Washing your hands often helps stop you from getting viruses. It is also important to get regular exercise and eat healthy food. All these can help you strengthen(增强)your immune system(免疫系统).

Good morning! My name is Cindy Smith. Look! This is my schoolbag. You can see two black pencils, a black pen and a brown pen are in it. A dictionary is in it, too. It's not mine. It's my friend Jane's. Is the baseball mine? No, it isn't. It's my brother David's. What's that? It's my sister Anna's CD. Oh, where is my ID card? It's not in my schoolbag. I lost it. If（如果） you find it, please call me at 328-3601. 

Thank you very much!

The first "forest library" in Shanghai recently opened to the public, giving readers the chance to relax and read in a natural environment. 

Known as Read & Joy Forest, the forest library was developed by Pudong New Area and Shanghai Library. It is in an urban (城市的) green space area near Shanghai Library East. It can make visitors take a pleasant walk in the quiet and green forest. 

People tried not to harm the forest when building the forest library. The library is in the open air and has facilities (设施) such as benches and an information boot h (亭). Wooden walkways connect green spaces. 

"I learned about the forest library from my friends. so I came here," said a 21- year- old college(大学) student. "The green outdoor environment helps reduce eyestrain (视疲劳). I will come back for sure. "

Most of the visitors to the forest library are young people and parents with their children. They read carefully or take a walk slowly in the forest. "I like the fresh air and the trees here. I've spent the whole morning indoors and wanted to get some fresh air. The library makes it possible to enjoy reading in nature. I feel very relaxed here," said one reader sitting on a bench.
