Do you know about aerotrain（气动悬浮列车）? A high-speed aerotrain can run 400 to 500 km per hour. What a surprising speed it is! And it is being developed by China and Japan together. It’s said that the model of this high-speed aerotrain is more than one metre long. The bullet-nosed（子弹头）car is like a high-speed train, and its body has wings, which are similar to the plan.

The aerotrain doesn’t run on traditional fuel resources（燃料资源）such as coal, gas or electricity. The train will be fully powered by natural energy. It will not only reduce costs but also improve the speed. The high-speed aerotrain is expected to change the world’s transportation situation, according to experts. People are looking forward to the type of high-speed aerotrain.

Lai Chenguang is a very famous expert. He comes from Chongqing University of Technology. He is good at this kind of technology in China. At the same time, he also takes part in the projects. He introduced that the first and second generation（一代）high-speed aerotrains have been tested. He believed that they could pass a series of strict tests smoothly.

“If the train runs at a speed of 500 km/h, it will use very little energy. The energy it consumes is only 1/3 of that of normal high-speed trains. It means that it will save more energy than normal high-speed trains,” Lai said. In addition, the passengers that the train carries will also be increased because of the new design.

According to a recent report, kids in primary school spend about six hours every week doing their homework.. So kids hate homework. However, their parents hate homework, too.

Is it good for kids to do homework? Of course, a great number of researches do show that kids can remember what they have learnt in class better by finishing their homework on time and homework itself plays an important role in developing their learning shills, such as independent thinking and creativity.

But for parents, the result is not the same. After a day of hard work, most of them feel like they’re going through school a second time when they sit down with their children each night to help with their homework. And a recent survey found that 46 percent of parents feel like they don’t spend enough quality time with their children, because they spend too much time doing the housework or helping with homework. And another 29 percent of parents have arguments with their kids often when they have different answers to the same question.

Now several education scientists strongly advise parents to stop helping. They say it will give their kids more independence and give parents back their free time. At the same time, the number of homework – connected arguments will be less at home. Katy Smith, an education scientist, says, “ You don’t have to know everything. Children need to put their hands up for help and so do parents. Use your resources – online teachers, or even your neighborhood – just ask.”
