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 Rivulus, 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 (圓木) 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(肺魚(yú)) found in Australia, Africa and South America can live out of water, but only in a not active(活波的)way. But no other known fish can be out of water as long as the Mangrove Rivulus 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.

Who do you admire(崇拜)?Different people may have different ideas.
If you’re a sports fan, perhaps the person you admire most is a great basketball player, and Yao Ming is probably the one in your mind. If you study music or play an instrument, perhaps the person you admire most is gifted musician like Mozart, who began to write beautiful music at a very young age. Or maybe you admire great scientists, for example, Yuan Longping.
We have many reasons to admire famous people and we often give much of our respect to them. However, we shouldn’t neglect those who are common, such as nurses, train drivers, firemen, cleaners and so on. They may be working in a corner of the world without being noticed, but all these people spend their working days serving the public. They show great dedication(奉獻(xiàn)).However, what they do is often unnoticed by us. Have you ever thought of what our life will be like if they stop working?
So next time when you appreciate famous people, don’t forget those who are common around you.

Many places in the world need more fresh water. Every country is trying to find ways to turn salt water into fresh. Why aren’t there many factories like the Symi factory?
In some places the sun is not hot enough. Or it does not shine every day.
In such places other ways of heating sea water can be used. These ways cost more money, but they work faster than the sun. By boiling sea water with high heat a lot of fresh water can be made quickly.
But heating is not the only way to get fresh water from salt water. Other ways are tried.

We’ve talked about snails (蝸牛) and their slow move. But much of the time snails don’t move at all. They are in their shells (殼) —sleeping.
Hot sun will dry out a snail’s body. So at the least sign of hot sun, a snail draws its body into his shell. A snail will die in a heavy rain. So when it rains, a snail does the same thing, too. A snail can sleep for as long as it needs to. It spends all the winter months in its shell, asleep.
In the spring the snail wakes up. Its body, about three inches long, comes out from the shell. When hungry, the snail looks for food. Its eyes, at the end of the top feelers (觸角), are very weak. But its sense (感覺(jué)) of smell is very strong. It helps the snail to find food and the new greens.
A snail’s mouth is no bigger than the point of a pin (大頭針). Yet it has 256,000 teeth! The teeth are very small, and you can’t see them. If you put a snail in a hard paper box, it will eat its way out! And if a snail wears out its teeth, it will grow new ones.

My class will put on a short play in English at the end of the year. Yesterday our English teacher gave us copies of the play.
“Choose a character in the play whom you’d like to be, ”she told us. “This afternoon learn a few lines of this part for homework. Then tomorrow you can say those lines in front of the class. Ill decide who play each part.”
I wanted to have one of the bigger parts in the play, so I choose the part of the king. He has a lot of lines to say. I learned them by heart.
This morning in our English lesson we had to say our lines. I acted the part of the king. When I said my lines, I put a lot of expression into my acting. I thought I acted really well.
Everyone in the class read a part and then the teacher who would play each part.
Many of the students in my class couldn’t act at all. They couldn’t even read without making lots of mistakes. I was sure that I would get a big part in the play.
However, the teacher gave me the part of a soldier. He has only one line. It is, “Yes, sir!”
I was very disappointed. At the end of the lesson I went up to her and asked her why I had such a small part.
“You put too much expression in your acting,” she said. “Good acting is not big acting. It is acting the audience can believe in.”
I think I know what she means.
