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.

      The next time you look up at the sky and see a cloud that looks like Mickey Mouse or your favorite fruit, look again. It may not be a cloud, but a Flogo -- a logo that flies. It's a new form of advertising in the sky that's never been used before. It's a different way to market your products, logos, and events.

     These funny logos are made with soap bubbles （肥皂泡） mixed with a little helium gas （氦气） ,which makes them lighter than air and float in the sky. Special machines are used to make these new funny Flogos. The machine, which can be rented for $ ,500 a day, can make a Flogo every 15-5 seconds.

      Flogos can fly much higher or lower if needed. They can last from a few minutes to an hour anywhere in the sky, depending on the weather conditions. Though they can fly up to 0, 000 feet, they usually float around at 300- 500 feet. Flogos are only white now, but people hope to have more colorful Flogos in the near future.

     Flogos are Green, 100% environmentally safe, because the soap used to make the Flogo comes from plants and leaves. So this fun way of advertising is healthy and good for the environment.

THIS IS HOW READING HAS CHANGED

Could you imagine being in a car driven by a computer, not a human? Recently, China has made a big step toward self- driving technology. Since August, driverless taxis can run on roads in Wuhan, Chongqing and Shenzhen. 

Why do we develop self- driving cars? Self- driving cars have many advantages. They use computers with many cameras which can sense all the objects close to the car and give the computers another route (路线) . Then the car can take people to the place where they want to go. For disabled or blind people, self- driving cars can also help them get around more easily. 

According to US Centers for Disease Control and Prevention, each year, more than 1. 35 million people are killed on roads around the world. It's reported that self- driving cars could reduce road accidents by 90 percent. The main cause of car accidents is human error (错误) . By using computers, self- driving cars don't make poor decisions or lose attention like humans do. 

But self- driving cars aren't perfect. If something unexpected on the road happens, self- driving cars can't react as fast as a human driver can. Also, during weather events like heavy snow, self- driving cars wouldn't see the lines on the road easily. It might lead to an accident. The car's computer system would be broken by someone, causing it to crash or change its direction. 

It's clear that there is a lot of work to do to make self- driving cars a common and safe sight on our roads. And China is taking the lead in making this happen. 

Everyone knows water is important to all living things. But do you know these interesting1 about water? 

Without water, the Earth would look 2 the Moon. People can live for a long time without food, but only 3 days without water. Scientists say about 70% of the human body is made up of water. Water4 up about 83% of our blood, 75%of our brain, and 80% of our lungs (肺). About 95% of a tomato is water, and about 80% of an apple is water. So 5 can we do to help with water problems? 

Keep a shower to 10 minutes or 6 time. It helps save much water. Use a broom to sweep the floor, the stair, the garage( 车 库 ) , or the sidewalk instead of water.

7 throw your used water away. Instead, you can use some to water plants or run the toilets. Use a bucket( 桶 )of water to 8 your bike or the family car instead of water pipes. 

Use water only 9 you need it. Don't leave water running. Be sure to tum the tap10 when you are not using it.
