A fish that lives in America can live out of water for months at a time, similar to how animals got used to land millions of years ago, a new study shows.

The Mangrove Rivulets, a kind of little fish, lives in small pools of water. When their living place dries up, they live on the land, said Scott Taylor, a researcher in Florida.

The fish can grow as large as three inches. They group together and breathe air through their skin before they can find water again.

The new scientific discovery came during a trip.

"We were travelling for fun. And one day I kicked over a log (圆木) and the fish came out." Taylor told reporters by telephone. He said he would make his study on the fish known to the public in an American magazine early next year.

In lab tests, Taylor said he found the fish can live up to 66 days out of water without eating.

Some other fish can live out of water for a short period of time. The walking catfish found in Southeast Asia can stay on land for hours at a time, while lungfish(肺鱼) found in Australia, Africa and South America can live out of water, but only in a not active(活跃的) way. But no other known fish can be out of water as long as the Mangrove Rivulets and keep active, according to Patricia Wright, a biologist at a Canadian University.

More studies of the fish may tell how animals changed over time.

"These animals live in conditions similar to those millions of years ago, when animals began to move from water onto land." Wright said.

In 1620, about half the USA was covered by forests. Today the forests have almost gone. A lot of good land has gone with them, leaving only sand. China doesn't want to copy the USA's example. We're planting more and more trees. We've built the " Great Green Wall" of trees across northern part of our country. The Great Green Wall is 7,000 kilometres long, and between 400 and 1,700 kilometres wide. It will stop the wind from blowing the earth away. It will stop the sand from moving towards the rich farmland in the south. More "Great Green Walls" are needed. Trees must be grown all over the world. Great Green Walls will make the world better.

In recent years advances in medical technology have made it possible for people to live longer than in the past. New medicines and machines are developing every day to extend life. However, some people, including some doctors, don't agree with these life extending measures, and they say that people should have the right(权利)t o die when they want, They say that the quality of life is as important as life itself, and that people should not be forced to go on living when conditions of life have become unbearable. They say that people should be allowed to die with dignity(尊严) and to decide when they want to die. Others don't agree and say that life under any conditions is better than death and that the duty of doctors is always to extend life as long as possible. And so the quarrel goes on and on without a definite(明确的) answer.

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.

Tigers are the largest wild cats in the world. They usually go out to hunt for food when it is dark. And they hunt alone most of time. When a tiger sees an animal, it moves quickly and then jumps on the animal to kill it. Sometimes it can take the tiger several days to finish eating its food. When the tiger is full, it will cover the dead animal with leaves. Later, when the tiger is hungry again, it comes back to eat some more.

Tigers are different from others in the cat family. They like water and often jump into rivers to swim. Some tigers live in very cold places-in North Korea, Russia and China. Other tigers live in warmer places-in India and parts of Southeast Asia.

But now all tigers are in danger. Some people kill tigers to use their skins for clothes, and their bodies for medicine. There is also less land for tigers to live on.

From the report we can see that, in 1990, forty percent of people stayed at home for their holidays. However, now the percentage has 4 to nine percent. More people go out for fun. People enjoy the 5 air, clean water and green hills when they go camping in places far from the city. In 1990, thirty－eight percent of people6 going to the seaside. However, in 20027 twenty seven percent were interested in going there. What great8 !

Why have those changes9 ? I think there are several reasons. First, it's because people can afford to travel. Second, people prefer to live a high-quality and colourful life. Third, their attitudes(态度) to relaxation have 10 changed. Fewer and fewer people want to save much money by living a simple life.
