Dolphins(海豚) live in a dark underwater world. It’s often impossible to see each other or anything else around them, so sound plays an important role in their survival. To communicate with each other, dolphins produce all kinds of sounds.

Only other dolphins understand what the sounds mean. Scientists haven’t uncovered their secret communication, except for one kind of whistle. It might last less than a second, but this whistle is a big deal. Why? Because these whistles are actually names of dolphins - and every dolphin has one. Scientists call these sounds a “signature whistle.” When other dolphins hear the whistle, they know which dolphin is calling.

Dolphins often hunt by themselves but still need to stay connected to the group. Since they can’t always see each other, dolphins use their signature whistles to check in with other dolphins hundreds of yards away. “In coastal areas, dolphins exchange whistles even when they’re a third of a mile apart,” says Greg Campbell, who studies animals. That means dolphins shout out to group members that might be nearly five football fields away.

What’s amazing is who names the baby dolphin. Not the mother. Not an auntie dolphin or another group member. Scientists believe the baby dolphin itself comes up with the signature whistle. Like human babies, a baby dolphin plays with sounds throughout its first year. While testing its sound skills, a baby dolphin is doing something amazing. It’s creating or figuring out its signature whistle. How or why it chooses its signature whistle is not clear. Studies show that most of the time the signature whistle is nothing like its mother’s or group members’ whistles.

When the baby dolphin is about a year old, its signature whistle is set. It repeats it often so the other dolphins learn to recognize it.

Deciphering(破译) dolphin names is just the beginning of figuring out what dolphins communicate about. Do they chat about sharks? Discuss the tides? Maybe they even have a name for people. Someday scientists are to decipher the rest of dolphins’ communication.

EACH of us fails from time to time. If we are wise, we accept these failures as a necessary part of the learning process. But all too often we convey to our children either by words or by actions that failure is something to be ashamed of, that nothing but top performance meets our approval.

Donnie was my youngest third-grader. His fear of failure kept him from classroom games that other children played excitedly. He seldom answered questions – he might be wrong. He seldom finished his work because he repeatedly checked with me to be sure he hadn’t made a mistake.

I tried my best to build his self-confidence. But nothing changed until midterm, when Mary Anne, a student teacher, was assigned to our classroom. She was young and pretty, and she loved children. My pupils, Donnie included, adored her. But even enthusiastic, loving Mary was baffled by this little boy who feared he might make a mistake.

Then one morning we were working math problems. Donnie had copied the problems with painstaking neatness and filled in answers for the first row. Pleased with his progress, I left the children with Mary. But when I returned, Donnie was in tears. He’d missed the third problem.

Mary looked at me in despair. Suddenly her face brightened. From the desk we shared, she got a canister (小筒) filled with pencils.

“Look, Donnie,” she said, “I’ve got something to show you.” She removed the pencils and placed them on his desk. “See these pencils, Donnie?” she continued. “They belong to Mrs. Lindstrom and me. See how the erasers are worn? That’s because we make mistakes too. Lots of them. But we erase the mistakes and try again. That’s what you must learn to do, too.”

She kissed him and continued: “I’ll leave one of these pencils on your desk so you’ll remember that everybody makes mistakes, even teachers.” Donnie looked up with love in his eyes and just a glimmer (少许) of a smile.

The pencil became Donnie’s prized possession. That, together with Mary Anne’s frequent encouragement and praise for even Donnie’s small successes, gradually persuaded him that it’s all right to make mistakes – as long as you erase them and try again.

The Washington post – NASA’s newest space habitat looks sort of like a kids’ moon bonce, a big, bright, inflatable globe that could be lots of fun to play in. Soon astronauts on the International Space Station could get the chance to try . The expandable habitat made by Bigelow Aerospace recently passed NASA’s strict certification requirements and is scheduled to be flown to the station in September.

Called the BEAM ( Bigelow Expandable Activity Module), the habitat would be attached to the space station, where it would stay for two years. While there, it would be tested to see how it handles the rigors of space – the radiation, the station’s movement and even how it stands up to the debris (碎片) flying around in orbit.

The private Las Vegas company, founded by millionaire real estate mogul(地产大亨) Robert Bigelow, won a $17.8 million contract from NASA to provide the module to the space station.

“Today is the first step, but it’s a big step,” said Bigelow’s George Zamka. Replace the space station or make it larger. It also hopes to build the habitats on the moon. Its B330 module would be even bigger, with 330 cubic meters of internal (内部的 ) space. The modules could be connected. Creating research facilities, the company says, or even space hotels.

In an interview ,NASA’s William Gerstenmaier, said he was eager to see how the module performs , and said he was especially pleased “ to see how the private sector can step up and help us meet our requirements.” The module will be flown to the space station by SpaceX, the first commercial company to resupply the space station.

1.What would be the best title for this passage?

A. NASA’s space habitats flown to the station.

B. NASA’s space habitat it the station.

C. NASA’s new expandable space habitat.

D. NASA’s newest inflatable globe.

2.Which of the following is TRUE according to the passage?

A. NASA’s newest space habitat is a kids’ moon bounce.

B. Astronauts of Bigelow Aerospace could get the chance to try the space habitat.

C. NASA was founded by Robert Bigelow.

D. The B330 module to be built on the moon would be with an inside space of 330 cubic meters.

3.The underlined word “rigors” in Paragraph 2 refers to “_________”.

A. difficulties B. environments

C. movements D. changes

4.The passage is most probably taken from ________.

A. a newspaper B. a booklet

C. a magazine D. a science fiction
