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.

举一反三
In many high schools，there are strict rules about using mobile phones. If your phone rings in class，for example，the teacher will be very angry.
Every mobile phone has a ringtone (铃声). It tells you that someone is calling you. Now，there is a ringtone called “mosquitotone (蚊子铃声)”. Using it，students can receive calls and text messages (短信) in class but the teacher will not realize what is happening. How?
Mosquitotone has a special sound. Only children and teenagers can hear it. As we get older，we are unable to hear some sounds with high frequencies (频率). As a result，a child or teenager can hear the mosquitotone ringtone, but it’s_inaudible_to someone 20 or older.
But sometimes，people over 20 can hear the ringtone. One British student’s phone uses mosquitotone. In class，the student’s phone rang. The 32yearold teacher looked at the student and became unhappy. “I heard that. You know the rule：no mobile phone in class.”
Not all the students are interested in mosquitotone. Jerry Jones，a high school student of 17，says，“Using mosquitotone too often is bad for our hearing. I may use it for pleasure，but not in class. It’s unfair to the teachers！”
What do parents think of mosquitotone？“I think it is perfect for places like movie theaters，” says Connie Neeson,44.“Think about it. Yon’re watching a film and someone’s mobile phone rings. Mosquitotone is good because many people don’t hear it. However，it also has a bad influence on their study if students use it in class.”
小题1:Mosquitotone works because ________.
| A．it is very loud | B．it has no sound |
| C．it has a beautiful sound | D．it uses high frequencies |
| A．it can’t be seen by | B．it can’t be heard by |
| C．it isn’t popular with | D．it isn’t healthy for |
| A．was late for class | B．didn’t do his homework |
| C．couldn’t answer her question | D．was using a mobile phone in class |
| A．has no bad influence | B．is unfair to the teachers |
| C．has its advantage and disadvantage | D．can’t be used in any public place |
Conflicts(矛盾）go between parents and children. It"s hard to tell who are right and who are wrong. A child of 7-8 always finds some reasons to have a conflict with it"s parents. Whether it is about some toy, studies, a party or a company, there is always a difference between them. And it becomes worse when they answer you back. Scientists tell us that children should be treated with care. Yes, sure they should respect their elders.
We are partly
responsible(有责任的）for this. At an early age we encourage children to behave like adults, just because we find it funny. The kids on the other hand consider this same behavior as normal and get used to it. And when it is not funny for us any more, we expect them to stop it, but by then it is already too late. Only when they reach a certain maturity will the children realize that answering back and being rude are not acceptable(可接受的).Until then, most of the time their behavior is difficult to change, unless by force(暴力）.And use of force is against the every good idea, as it weakens the child"s confidence.So it is one thing to bring a child into this world but quite another to make them into well mannered citizens. The best way is to be a goo
d example ourselves, as our children are the mirrors of us adults. 小题1:_______are all lovely and lively.
| A．Children | B．Toddlers | C．Kids | D．Grown-ups |
| A．fathers and mothers | B．parents and children |
| C．parents and toddlers | D．parents and parents |
| A．学期 | B．阶梯 | C．知识 | D．成熟 |

| A．Children often copy what their parents do. |
| B．Children can not change their behavior. |

| B．to give examples on educating children |
| C．to show the growth of children |
| D．to show the behavior of children |
Sitting on exercise balls brings more than a smile to students and teachers.
Some fourth-graders at Conrad Weiser West Elementary School in Womelsdorf love their new chairs-—probably because they"re not really chairs at all.
The kids are sitting on the air-filled balls. But different from those just for exercise, these have small legs that keep them from rolling. Sitting on a chair all day in school can make anyone want to move around. So, more and more teachers are letting students have a ball. By using exercise balls instead of common chairs, teachers find students" posture(姿势) and attention improved.
Dotti Pownall, a fifth-grader teacher in West Virginia, has been using balls as chairs since December 2008. "The students love them." she says. Pownall took a survey of her students. She found that 80 percent, thought sitting on the balls helped them concentrate(专注) better:
"Besides, they’re fun,b" says Pownall.
According to WittFitt,b a company that has sold balls to more than 200 schools, they can improve kids" posture and classroom behavior.
Exercise ball chairs are getting popular in classrooms, from preschool to college. Some adults (成人) even use them at work.
Lisa Witt felt so stro
ngly about the use of balls as chairs that she started WittFitt. She said the company not only encourages the use of balls but also educates teachers and students on how to use them. "We sell balls in 24 s
tates in America, three provinces in Canada and Japan." says Witt.小题1:Sitting on exercise balls can______.

Now scientists say the microbes on our hands cou
ld be used in a surprising way; fighting crime, According to a recent survey microbes as well as fingerprints(指纹) could be used to indentify the criminal. Everyone has his own set of microbes on the hands. That is to say, if you and your best friend were able to see and compare all the microbes on your hands, your hands probably would look different. Some microbes only show up on your hands while others live only on your friend"s hands.
When you work on a computer you leave the microbes from your hands on the keyboard. The scientists can easily tell the owner of the keyboard by looking at the microbes on it. Even if you don"t leave your fingerprints behind, your microbes may give you away.
Noah Fierer, a scientist, says. "You can only clean a fingerprint, but you can"t sterilize (使无菌
) a surface j
ust by wiping(擦) it off," He says that scientists have a lot more work to do before the microbe is used as a useful tool.小题1:According to the passage,_______ could be used to identify the criminal.
