Now, it seems that artficial 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 player' skill levels (水平). Then it uses the information to change the ways to play. If the player 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 to try their beat with words like "Good job!", "Come on!" and so on. At the same time, it gives some good advice to improve their skills. So it is both a good partner and a 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.

Mushrooms are small living things that look like umbrella. They are not plants because they do not have the green material that plants use to make food. Mushrooms get their food from the living or dead plants around them.
A mushroom has two parts: the mycelium(菌丝体) and the fruit. Mycelium is underground and gets food for the mushroom. Sometimes it dies quickly, but if it gets enough food it may live for hundreds of years.
The fruit, umbrella-shaped body, only lives for a few days. Gil(菌褶), small plants under the mushroom's cap, have small spores(孢子) on them. When these spores fall off the mushroom the wind blows them away. If they fall on a warm, wet area a new mycelium develops.
Some mushrooms can be eaten with plenty of vitamin B and also minerals like iron. They are sold at high price.The best-known and most widely eaten is the button mushroom(草菇). They are found in all kinds of food, from pizzas to salads.
Truffles(松露) are mushrooms that grow completely underground. Dogs and pigs can find the places where they grow by using their noses. The mushrooms cost a lot of money and can be eaten in very expensive restaurants around the world.
Some types of mushrooms are poisonous(有毒的). They lead to illness, and a few mushrooms are even deadly. One is a beautiful white mushroom which grows in summer and autumn, Unless you get quick treatment death may come very fast.
It's hard for people to tell between safe and poisonous mushrooms. So,never eat a mushroom you find unless you know what it is.
Mushrooms help plants grow. They help dead material and minerals get back into the soil so that it can be used again.
The Chinese have used mushrooms in medicine for hundreds of years. Some types are turned into a medicine that gives strength or energy. Scientists have found out that some mushrooms prevent high blood pressure(高血压).
