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 (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.

During the day, you spend a lot of time running, jumping, laughing, eating, and talking. You use up a lot of energy(能量) , and by the end of the day you're tired. Sleep gives your body a chance to rest.
But your brain (大脑)and body are not completely at rest during sleep. While you sleep, your mind may think of the things that happened during the day. It keeps the important things in mind as memories(记忆). It also thinks about things you were worrying about, and you may wake up with answers to some of your problems.
You also grow while you sleep. The thing called "human growth hormone (荷尔蒙)" in the body helps you grow during sleep. This growth hormone also helps the body to repair itself.
Sleep helps your body to conserve energy too. You use up a lot of energy during your daily activities. But when you sleep, your body temperature falls, and your "metabolism" (新陈代谢) slows down. You are still using some energy, but much less than when you are awake and active.
Have you ever stayed up past your bedtime? Did you have difficulty getting up the next morning? Maybe you had problems seeing clearly or you cannot think clearly. That was your body's way of saying, "I need sleep!" A lack ( 缺乏) of sleep can stop your body and mind from working correctly.
【小题1】What does "human growth hormone" do while people sleep?
A.It helps people rest well.B.It helps repair the body.
C.It helps answer problems.D.It helps slow the body down.
【小题2】According to the passage, which of the following tells you need sleep?
A.You use up a lot of energy.B.You enjoy daily activities.
C.Your body temperature falls.D.You don't want to get up.

A.provideB.moveC.saveD.spend

A.Sleep is very important.B.The brain needs enough sleep.

When women sit together to watch a movie on TV, at the same time they usually talk about a lot of subjects, including children, men, careers and what’s happening in their lives. When groups of men and women watch a movie together, the men usually end up telling the women to shut up. Men can either talk or watch the screen---they can’t do both---and they don’t understand that women can. Besides(此外), women think that the point of all getting together is to have a good time and develop relationships--not just to sit there like couch potatoes staring (盯着) at the screen.
During the ad breaks, a man often asks a woman to explain the plot(the story that is told in a novel or play or movie etc.) and tell him where the relationship between the characters is going. He is unable, unlike women, to read the small body language signals that show how the characters are feeling emotionally(情绪上). Since women originally spent their days with the other women and children in the group, they developed the ability to communicate successfully because they want to keep relationships. For a woman, speech continues to have such a clear purpose: to build relationships and make friends. For men, to talk is to connect to the facts.
Men see the telephone as a communication tool for sending facts and information to other people, but a woman sees it as a way of keeping relationship. A woman can spend two weeks on vacation with her girlfriend and, when she returns home, telephone the same girlfriend and talk for another two hours.
There is no convincing(令人信服的)evidence that social conditioning, the fact that girls’ mothers talked them more, is the reason why girls talk more than boys. Psychiatrist Dr. Michael Lewis, author of Social Behaviour and Language Acquisition, conducted experiments that found mothers talked to and looked at baby girls more often than baby boys. Scientific evidence shows parents reply to the brain differences of their children. Since a girl’s brain is better organized to send and receive speech, we talk to them more. As a result, mothers who try to talk to their sons are usually pointed to receive only short complaints in reply.
【小题1】While watching TV with others, women usually talk a lot because they ___________.

A.are afraid of silence with their families and friends
B.can both talk and watch the screen at the same time
C.think they can have a good time and develop relationships
D.have to explain the plot and body language to their husbands
【小题2】After a vacation with her girlfriend, a woman would talk to her again on the phone for hours so as to ___________.
A.experience the happy time again
B.keep a close tie with her
C.recommend her a new wonderful place
D.remind her of something forgotten
【小题3】What does the writer want to tell us most?
A.Women’s brains are better organized for language and communication.
B.Women love to talk because they are more sociable than men.
C.Men do not like talking because they believe more in facts.
D.Social conditioning is not the reason why women love talking.
【小题4】Which of the following would be the BEST title for the passage?
A.Women Are Socially Trained to Talk
B.Talking Keeps Relationships
C.Women Love to Talk
D.Men Talk Differently from Women
