March 21 has been declared World Sleep Day, a time to recognize and celebrate the value of sleep. Many sleep experts hope it will be a wake-up call.
According to a poll (民意调查）by the National Sleep Foundation, nearly 4 in 5 Americans don’t get as much sleep as they should during the workweek. On average, adults are thought to need at least eight hours of sleep a night, although some can manage with less and some won’t do well without more. But the survey found that, on workdays, only 21% of Americans actually get a full eight hours of sleep, and another 21% get less than six.
To many of us, the thought of spending more time sleeping is, well, a big yawn. On the other hand, the thought of being smarter, thinner, healthier and more cheerful has a certain appeal. And those are just a few of the advantages that can be ours if we consistently get enough sleep, researchers say. Also on the plus side: We’re likely to have better skin, better memories, better judgment, and, oh, yes, longer lives.
“When you lose even one hour of sleep for any reason, it influences your performance the next day,” says Dr. Alon Avidan, director of the UCLA Sleep Disorders Center.
A study published last year found the same to be true even of children. When kids aged 8 to 12 slept for just one hour less for four nights, they didn’t function as well during the day.
But sleeping has an image problem. “We see napping or sleeping as lazy,” says Jennifer Vriend, a clinical psychologist in Ottawa, Canada, and the leading author of the study with children. “We put so much emphasis on diet, nutrition and exercise. Sleep is in the back seat.” In fact, she adds, no matter how much we work out, no matter how well we eat, we can’t be in top physical shape unless we also get plenty of sleep.
The underlined part in Paragraph 1 means _____.
| A．To wake up the sleepers |
| B．To draw people’s attention |
| C．To serve as a morning call |
| D．To declare the special day |
From Paragraph 3 we can infer that _______
| A．Being healthier is one of the advantages for us |
| B．Sleeping has nothing to do with one’s expectations |
| C．Spending more time on sleeping is a waste of time |
| D．Enough sleep is the guarantee of the appealing things |
What Jennifer Vriend said in the last paragraph implies that _______.
| A．Sleeping is an image problem |
| B．People care little about sleeping |
| C．Lazy people tend to sleep long |
| D．Sleeping is only part of our life |
What is the purpose of the passage?
| A．To talk about people’s sleeping problems. |
| B．To provide an investigation result of sleeping. |
| C．To arouse the awareness of enough sleeping. |
| D．To stress the function of sleeping at night. |
Looking back on my childhood, I believe that naturalists are born and not made. Although we were all brought up in the same way, my brothers and my sisters soon gave up their flowers and insects. Unlike them, I had no ear for music and languages. I was not an early reader and I could not do maths well.
Before World War I we spent our summer holidays in Hungary. I have only the dim memory of the house we lived in, of my room and my toys. Nor do I remember clearly the large family of grandparents, aunts, uncles and cousins who gathered next door. But I do have a crystal clear memory of the dogs, farm animals, local birds, and above all, insects.
I am a naturalist, not a scientist. I have a strong love for the natural world and my passion has led me into varied explorations. I love discussing my favorite topics and enjoy burning the midnight oil reading about other people’s observations and discoveries. Then something brings these observations together in my mind. This has resulted in my publishing 300 papers and books.
But curiosity, a keen （敏锐的）eye, a good memory and enjoyment of the animal and plant world do not make a scientist. A scientist, up to a point, can be made. A naturalist is born. If you can combine the two, you get the best of both worlds.The first paragraph tells us the writer .
| A．was interested in flowers and insects in his childhood |
| B．lost his hearing when he was a child |
| C．didn’t like his brothers and sisters |
| D．was born into a naturalist’s family |
The writer can’t clearly remember his relatives probably because .
| A．he didn’t live very long with them |
| B．the family was very large |
| C．he was too young when he lived with them |
| D．he devoted himself to observing nature |
It can be inferred from the passage that the writer was .
| A．a scientist as well as a naturalist |
| B．not a naturalist but a scientist |
| C．only a born naturalist |
| D．first of all a scientist |
According to the writer, a born naturalist should first of all be .
| A．good at maths | B．full of passion |
| C．knowledgeable | D．self-controlled |
In 1883, a creative engineer named John Roebling was inspired by an idea to build a great bridge connecting New York with the Long Island. However, bridge building experts thought that this was an impossible project and told Roebling to forget it. But Roebling could not ignore the vision of this bridge. After much discussion and persuasion he managed to convince his son Washington, an engineer, that the bridge could be built.
The father and son developed concepts of how it could be completed and how the difficulties could be overcome. After that, they began to build their dream bridge.
The project started well, but when it was only a few months underway (在进行中) a tragic accident on the site took the life of John Roebling. Washington was also injured and left with a certain amount of brain damage, which made him unable to walk or talk or even move.
Everyone had a negative comment since the Roeblings were the only one who knew how to build the bridge. In spite of these difficulties, Washington was never discouraged and still had a burning desire to complete the bridge. It seemed that there was a message for him not to give up. Suddenly an idea hit him. All he could do was to move one finger and he decided to make the best use of it. By moving it, he slowly developed a code of communication with his wife. Then he used the same method of tapping her arm to tell the engineers what to do. The project was underway again. For 13 years Washington tapped out his instructions with his finger on his wife's arm, until the bridge was finally completed.
Today the Brooklyn Bridge stands in all its glory to the victory of one man's determination not to be defeated by circumstances. This is one of the best examples of a never-say-die attitude that overcomes a terrible physical disability and achieves an impossible goal.

Islamabad, Pakistan, June 22nd---Two mountain climbers surprisingly survived (幸免于) a fall of over 500 feet on the 25,530-foot mountain in Pakistan, Saturday. The two climbers were climbing an ice-covered wall of the mountain when they suddenly lost their footing and fell about 560 feet to a narrow snow-covered ledge(悬崖突出部分) below. “We were lucky that ledge was there,” said the climbers, “Otherwise, we would have fallen over 2,000 feet.” If the ledge had not been there, the two climbers almost certainly have met their death. “It’s a wonder,” the climbers said, “that we landed on the ledge, and the snow was loose enough to cushion(缓冲) our fall. We’re thankful that we survived.”
When a reporter asked them if they planned to give up mountain climbing after their narrow escape(九死一生), the two climbers replied, “Not at all. We’ll be goin
g back up there just as soon as we get out of the hospital.” The mountain climbers survived because _____.
| A．they had fallen only 500 feet down | B．of the ledge and the loose snow on it |
| C．of their strong bodies | D．they were very good climbers |
If there had not been
the snow-covered ledge, _____.
| A．they wouldn’t have fallen down | B．they would have them wounded |
| C．they would have lost their lives | D．they would fall into the deep snow |
How high was the ledge from the foot of the mountain?
| A．2,560 feet high | B．2,000 feet high |
| C．25,530 feet high | D．More than 1,400 feet high |
