Several Asian hospitals are doing experiments with tele-medicine. Tele-medicine is a technology that allows doctors to "see" patients without them being in the same place. This is made possible through high-speed communication networks(网络). At both ends of the line, the way of video-meeting lets them see and talk to each other. Blood pressure (血压) and body temperature are directly shown on computers.

    Tele-medicine is already in wide use in some places such as the United States and Germany. Among other uses, village doctors hold "consultations (会诊)"with far-away experts(专家). The experts can also help them during operations.

    Tele-medicine has been slow to reach Asia because of high costs besides other reasons. When things improve, this technology will develop very fast. Chinese University of Hong Kong's medical school has joined a big hospital in Beijing, and Thailand is building a tele-medicine station connecting 20 areas.

    Tele-medicine will do good to patients because doctors from different places can see them and give their medical advice. The help is quite important if the disease is an unusual one. It also helps spread medical knowledge among experts.

    As tele-medicine develops well, its costs will be lower and it will become very popular in the medical field.

    Lockheed Martin, American space system company (空间系统公司) has found a really cool way to inspire the young minds of today to the research fields in Science, Technology, Engineering and Math (STEM).

    It may look like a normal yellow bus, but all the magic happens once you get inside. Meet the “Mars (火星) Experience Bus,” part of Lockheed Martin's new “Generation Beyond” national education program to get the kids joining in studying what goes on outside of our home planet. The bus offers a virtual reality (VR, 虚拟现实) experience making the teenagers feel like they are driving on Mars.

    The VR experience was developed by taking advantage of software (软件) created for today's best video games, so you can imagine the picture shown is top level. The kids do seem really excited to see the bus take a virtual trip on the red planet and search unknown places. It's certainly a great way of learning about the universe by virtual reality working on a common bus.

    The Lockheed Martin's bus will start a tour in the United States to allow kids from different parts of the country to take a ride in it. The Generation Beyond project also includes an iPhone app for iOS providing real-time information about weather reports for Mars, and there's also a free deep space course for middle school teachers and students.

    As space science develops, man has learned more and more about space. Space is not only amazing but also dangerous. While working in space, spacemen are facing danger.

    Scientists have found out that radiation(辐射) is the greatest danger to spacemen in space. When spacemen are working in space, they are in danger of radiation from the sun and other stars, which is bad for their health. Some special medicine may work a little, but there's no really helpful medicine.

    Space junk is also thought a great danger to spacemen. It's reported that there are 9,000 man-made things flying in space. About 30% of these are man-made satellites(卫星),10% are spaceships, and the rest are space junk. An explosion(爆炸) in 1996 made a cloud of 300,000 fragments(碎片), each at least 4 mm in size, and even a small piece of these knocked against a spaceship window and did some damage. Scientists are working on helpful ways to do with space junk.

    Although space is really dangerous, it interests everyone on the earth. In the near future, it may become usual for people to spend a few days in a space hotel. We may even choose to leave the earth and live in space for a few years. So we should care for space and do something to help improve the space environment.

    Nowadays, lots of foreigners are learning Chinese. Like many of them, I 1 knew two words of Chinese ("Ni Hao" and "Xie Xie") when I first came to Beijing, China in 2009. As you can guess, my life was 2 for a while after I arrived. Simple tasks like ordering food or taking a taxi were quite stressful.

    I knew I had to learn more Chinese, so I 3 a Chinese class. My teacher was 4, although I didn't learn enough to have a real conversation. Later I studied on my own as well, but my progress was still slow. And I decided to 5.

    Around this time, I started playing in a band with a Chinese man who became one of my best friends in Beijing. He taught me a lot of 6 about music, such as "melody". He learned a lot of English from me in return, so it was a good way to 7 language and culture.

    I have learned enough Chinese to 8 many problems like booking train tickets. These days, there are more foreigners who are studying Chinese. I can 9 why it's an amazing language. Finally, I found that the best way to learn a 10 is to make friends with native speakers and spend time with them.
