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.

Do you like crocodiles (鳄鱼) ? Do you know anything about crocodiles? Crocodiles appeared about two hundred million years ago. They once lived on the earth together with dinosaurs.

Crocodiles only live where it is wet and hot. They spent most of their time lying around in the mud (泥) or the rivers. The crocodiles’ long tails are used when the animals are swimming. It can be swung (摇摆) with great speed and force (武力). One blow will knock down a man or even a big animal at once. Crocodiles are very well protected against their enemies by the hard bone plates (骨板) which cover most of their bodies, but because of the way their neck are formed, they can only see in front of themselves. With their rows of terrible sharp teeth, they catch food, which may be a fish, an animal or even a careless man, and then hold it below the water until it drowns (淹死). Crocodiles lay their eggs and leave them under leaves or sand. Baby crocodiles have special sharp teeth with which to break their way out of the shells (壳) on their own. Crocodiles were once all over the world. But in the past 50 years, the number of crocodiles has gone down rapidly because of humans. The long-nosed crocodile is shy and because of this, the people of West Africa sometimes catch it for food. But more people hunt them for expensive crocodile leather. Now this kind of ancient animal has to depend on humans to live. Isn’t that terrible?

Do you know something about tree rings? Do you know they can tell us what the weather was like, sometimes even hundreds of years ago?

A tree will grow well in a climate with lots of sunshine and rainfall. And little sunshine or rainfall will limit the growth of trees by studying the tree rings. For example, to find out the weather of ten years ago, count the rings of a tree from the outside to the inside.
