Can plants eat people? Probably not, but there are many plants that eat meat. Some of them are big. And they can eat small animals. One famous meat-eating plant is Venus Flytrap(捕蝇草). 

Venus flytrap is a very strange plant. It grows in dry parts of the United States. Its leaves are like the pages of a book. They can open and close very quickly. Inside the leaves, there are three small hairs. If a fly touches one of the hairs, the leaf closes quickly， so the fly cannot get out. In about half an hour, the leaf presses the fly until it is dead. Then, the plant covers the fly and slowly eats it.

Why do plants do that? Most plants get what they need from the sun, the air, and the ground. In some places, the ground is very poor. It doesn't have all these important things, especially nitrogen (氮). Animal meat has a lot of nitrogen, so some plants eat meat to get what they need. Let's hope that bigger plants don't get the same idea!

   Several companies are racing to produce electronic paper and ink, complete with colors and moving imagines(图像). One idea would be to create a newspaper like The Daily Project in the Harry Potter books. Its pages would hold video clips of baseball games instead of just black-and-white photos.

   Electronic paper is not a new idea. A company in Massachusetts called E ink, for example, has been working for years on such a technology. Little electricity determines(决定)whether each microsphere(灌球)looks black or white at any given time. Together, microspheres make up words and imagines. The techniques seems promising for creating still imagines that can be changed when needed, but the process(进程)is too slow for good videos.

Scientists in the Netherlands now report a new type of e-paper technology. By using layers(层) of oil, the requirements. They can also make images which change fast enough to meet standard video requirements. They can also make brilliant colors. So far, however, each image is smaller than the fingernail.

For now, readingand watching TV will have to return two separate activities. Keep your eyes open, though, in the future, TV watching and reading might be part of the same work.

    The earth moves round the sun, and the moon goes round the earth. When our part（部分） of the earth turns to the sun, it is day, When our part of the earth turns away from the sun, it is night. The sun is much bigger than the moon. But sometimes the moon looks bigger than the sun, because it's much nearer to the earth. The sun is very bright. It gives a very strong light. The moon looks quite bright, too. But it doesn't give any light at all. The moon looks much bigger and brighter than the stars .But actually（事实上）, the stars are much bigger and brighter than the moon. They look smaller than the moon because they're much farther away from us.

    Three powerful ocean storms hit the Caribbean, the coast of the southeastern United States and southeastern Mexico. They come as the state of Texas recovers from Hurricane Harvey (飓风哈维). The huge storm caused serious flooding and billions of dollars in damage in Houston, the country's fourth-largest city.

    Hurricane season in the Atlantic Ocean goes from June 1 to November 30. And most storm activities happen in me month of September.

    Hurricanes are the most powerful storms in the Earth's atmosphere. The storms have different names depending on where they take place. Scientists call all these storm tropical cyclones (热带气旋).

    If the storms form over the Atlantic Ocean or eastern Pacific Ocean, they are called hurricanes. Storms that form in the western Pacific Ocean are known as typhoons. In the Indian Ocean, they are called cyclones. Although they have different names, all these storms form in the same way.

    Scientists at the American space agency NASA describe tropical cyclones as huge weather "engines" that use warm, moist (潮湿的) air as fuel.

    They can only form over warm, tropical waters near the equator (赤道).

    A tropical cyclone develops when warm moist air near the surface of me ocean rises. This creates an area of unusually low air pressure.

    Higher-pressure air from surrounding areas pushes in to take the place of the warm, rising air. It becomes warmer and moister and rises, too.

    The rising, moist air goes high into the atmosphere, where temperatures are low. This creates wind. The moisture forms clouds. The developing weather system begins to spin because of the Earth's rotation (旋转).

    As the storm spins faster and faster, an "eye" of the storm develops at its centre. This is a calm area of very low pressure. Higher pressure air from above flows down into the eye.

    Now, it seems that artificial intelligence(人工智能) is becoming more and more popular in our life, and it has greatly influenced the ways we live, work and play. Can you imagine that you can play table tennis with a robot one day?

    Recently, a scientist has invented a special robot that can be a table tennis coach. That means people can practice table tennis not only with humans but also with a robot.

    Named Forpheus, the smart table tennis robot is quite special. It can study the movements of human players and the speeds of the ball. In this way, it can exactly judge(判断) the players' skill levels(水平).Then it uses the information to change the ways to play. If the players are just beginners, Forpheus will play in a slow and easy way, but if the players are better ones, the robot will play in a faster and more difficult way. What's more，while playing, it encourages players 10 try their best with words like "Good job!" "Come on!" and so on. At the same time, it gives some good advice to improve their sill so it is a good partner and clever coach.

    Science and technology is developing quickly these days and it's hard to imagine what will happen in the future." In the next 20 years, it will be possible that one robot teaches another to play table tennis or even invents another one!" Takuoya, the inventor of the robot, said.
