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 (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 Rivulets and keep active, according to Patricia Wright, a biologist at a Canadian University.&科
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.

Last week, 169 Junior One students at No. 35 Middle School of Shenyang took their first no teacher exam. After the teacher handed out the exam papers, he left the room and never came back. A student collected in the papers when the exam was over.
“That test was not only a test of knowledge, but also a test of morality(道德). We wanted to show the students how important honesty(誠(chéng)實(shí))is,” said the school’s headmaster. Next year, it wants 80% of its exams to be without teachers. But students have different ideas.
“I was happy and excited during the exam because my teachers trusted(信任)me,” said a 15-year –old girl in Class 11.
“Schools must trust students a lot and do not use invigilators(監(jiān)考人)in exams. But I think it is too early. Some students will cheat(作弊)if there are no invigilators. And the students will not be able to ask for help when they need,” said another student.
“I don’t like having invigilators in exams. When they walk around the classroom, they make me nervous. I would get higher marks without them in the room because I would feel more relaxed,” a third student said.
“I think it’s very important to have invigilators in exams. Many students want to check their answers with each other after they have finished papers. And invigilators can also keep the classroom in order when something unusual happens. They may make me nervous, but I still think we need them,” a girl student said.
No-teacher exams may be a good idea. But before using them, schools must tell students the importance of honesty and try to find ways to solve something unusual in exams.
小題1:Why did No. 35 Middle School of Shenyang hold a no – teacher exam?
A.Because the teachers were too busy with their work.
B.Because it wanted to show the students the importance of honesty.
C.Because the students didn’t need their teachers to invigilate.
D.Because the headmaster wanted to know who cheats in exams.
小題2:How many students don’t agree to no-teacher-exams mentioned in this passage?
A.OneB.TwoC.ThreeD.Four
小題3:What does the underlined word “them” in the last paragraph refer to(指代)?
A.StudentsB.TeachersC.InvigilatorsD.No-teacher exams
小題4:Which of the following is TRUE according to the passage?
A.More students will cheat if there are no invigilators in exams.
B.No-teachers exams can make students honest and get good grades.
C.Most students are worried about having no invigilators in class exams.

Recently, a solar-powered (太陽(yáng)能動(dòng)力的) plane took to the sky for the first time. It passed an important test on the way to travel around the world.

The plane took off from an airport in Switzerland. It slowly rose above the fields and into the sky.
“There has never been an airplane of that kind that could fly — never an airplane so big, so light, using so little energy,” said Bertrand Piccard, a leader of the project.
During the 90-minute flight(飛行), the plane did several turns. It climbed nearly 1.6km above the countryside.
Engineers plan to test a night flight before July. Then they will use the results of the tests to build a second plane. They plan to travel around the world in that plane in 2012.
“We want to fly it day and night with no fuel (燃料),” Piccard said.
Piccard and pilot(飛行員) Andre Borschberg will take the plane around the world. They will make a few stops to change places and rest after a long time in the air — and to show off their airplane.
The plane will fly at 70 km per hour on average(平均). That is faster than a bike and slower than a car. The pilots will keep the plane in the air for up to five days at a time.
小題1:The passage is probably taken from _____________.
A.a(chǎn) postcardB.a(chǎn) newspaperC.a(chǎn) comic bookD.a(chǎn)n advertisement
小題2:The solar-powered plane ________________.
A.is big and heavyB.uses much energy
C.passed the first testD.will have a night flight after July
