Do you find getting up in the morning so difficult that it's painful ? This might be called laziness, but Dr. Kleitman has a new explanation. He has proved that everyone has a daily energy cycle.
During the hours when you labour through your work you may say that you're "hot". That's true. The time of day when you feel most energetic is when your cycle of body temperature is at its peak . For some people the peak comes during the forenoon. For others it comes in the afternoon or evening No one has discovered why this is so , but it leads to such familiar monologues(自言自语) as : "Get up, John! You'll be late for work again !" The possible explanation to the trouble is that John is at his temperature-and -energy peak in the evening. Much family quarrelling ends when husbands and wives realize what these energy cycles mean, and which cycle each member of the family has.
You can't change your energy cycle, but you can learn to make your life fit it better. Habit can help, Dr. Kleitman believes . Maybe you're sleepy in the evening but feel you must stay up late anyway . Counteract(对抗/抵消)your cycle to some extent by habitually staying up later than you want to .If your energy is low in the morning but you have an important job to do early in the day, rise before your usual hour. This won't change your cycle, but you'll get up steam and work better at your low point.
Get off to a slow start which saves your energy. Get up with a leisurely yawn and stretch . Sit on the edge of the bed a minute before putting your feet on the floor . Avoid the troublesome search for clean clothes by laying them out the night before. Whenever possible, do routine work in the afternoon and save tasks requiring more energy or concentration for your sharper hours.If you wants to work more efficiently at your how point in the morning, you should _____.
A.change his energy cycle | B.overcome his laziness |
C.get up earlier than usual | D.go to bed earlier |
You are advised to rise with a yawn and stretch because it will _____.
A.help to keep your energy for the day's work |
B.help you to control your temper early in the day |
C.enable you to concentrate on your routine work |
D.keep your energy cycle under control all day |
What’s the best title of the passage?
A.Change Your Habits | B.Save Your Energy |
C.Daily Energy Cycle | D.Temperature- and-Energy Peak |
The text is probably taken from a _________.
A.news report | B.research paper | C.medical textbook | D.fashion journal |

“Children who eat less salt and drink fewer sugar-sweetened soft drinks may significantly lower their risks of obesity,” researchers recently reported in the journal Hypertension.
“Sugar-sweetened soft drinks are a significant source of calorie intake in children,” said Feng J. He, a researcher at St George’s University of London, England. “It has been shown that sugar-sweetened soft drink consumption is related to obesity in young people.” They wanted to know whether there is a link between salt intake and sugar-sweetened soft drink consumption.
Dr He and colleagues analyzed data from a 1997 national survey of more than 2,000 people between 4 and 18 in Britain. “We found that children eating a lower-salt diet drank less fluid,” said He. “From our research, we estimated that 1 gram of salt cut from their daily diet would reduce fluid intake by 100 grams per day.”
The researchers also found that children eating a lower-salt diet drank fewer sugar-sweetened soft drinks. From their research, they predicted that reducing salt intake by 1 gram each day would reduce sugar-sweetened soft drink consumption by 27 grams per day, after. “If children aged 4 to 18 cut their salt intake by half, there would be a decrease of about two sugar-sweetened soft drinks per week per child, so each child would decrease calorie intake by almost 250 kilocalories per week,” Dr He said.
In previous studies, researchers found that a low-salt diet lowers blood pressure in children, and prevents the development of high blood pressure later in life. “Both high blood pressure and obesity increase the risk of having strokes and heart attacks,” Dr He said.
Dr He recommends that parents check labels and choose low-salt food products. “Small reductions in the salt content of 10 to 20 percent cannot be detected by the human salt taste receptors (感受器) and do not cause any technological or safety problems,” Dr He said.
5. According to the passage, obesity is directly linked to ______.
A. high-salt foods

B. a low-salt diet keeps children out of high blood pressure
C. children face the risk of having strokes and heart attacks
D. low-salt food products do not do harm to people’s health
7. Which of the following statements would Dr He agree to?
A. The less salt people eat, the healthier people become.
B. Children should reduce fluid intake in their daily life.
C. No high-salt food products will be available in shops.
D. A low-salt diet may prevent both high blood pressure and obesity.
8. After reading the passage, who should take effective action?
A. Children.
B. Parents.

A qualified doct who rarely practiced but instead devoted his life to writing. He once said: “Medicine is my lawful wife, and literature is my lover.” Russian writer Anton Pavlovich Chekhov, was a great playwright and one of the masters of the modern short story.
When Chekhov entered the Moscow University Medical School in 1879, he started to publish hundreds of comic short stories to support his family. After he graduated, he wrote regularly for a local daily newspaper.
As a writer he was extremely fast, often producing a short story in an hour or less. Chekhov’s medical and science experience can be seen through the indifference(冷漠) many of his characters show to tragic events. In 1892, he became a full time writer and published some of his most memorable stories.
Chekhov often wrote about the sufferings of life in small town Russia. Tragic events control his characters who are filled with feelings of hopelessness and despair.
It is often said that nothing happens in Chekhov’s stories and plays. He made up for this with his exciting technique for developing drama within his characters. Chekhov’s work combined the calm attitude of a scientist and doctor with the sensitivity(敏感) of an artist.
Some of Chekhov's works were translated into Chinese as early as the 1940s. One of his famous stories, The Man in a Shell, about a school teacher’s extraordinarily orderly life, was selected as a text for Chinese senior students.

Washoe, a female chimpanzee (黑猩猩) believed to be the first non-human to acquire human language, has died of natural causes at the research institute where she was kept.
The chimp died on Tuesday night, according to Roger and Deborah Fouts, co-founders of The Chimpanzee and Human Communications Institute in Washington, where she lived.
Washoe was born in 1965 in Africa, where she was captured by the Air Force and taken to the US for research use in the space program. In 1966, she left the program and began living with two scientists, Allen and Beatrix Gardner, who led a project to teach the chimp American Sign Language (ASL) in Washoe, Nevada, for which it was named. Washoe had been living on Central Washington University’s Ellensburg Campus since 1980. She had a vocabulary of about 250 words. Also, Washoe taught sign language to three younger chimps: Tatu, 31, Loulis, 29, and Dar, 31
Primate (灵长类) researcher Jane Goodall, in Fouts’ book Next of Kin, noted the importance of the work with Washoe. “Roger, through his ongoing conversations with Washoe and her extended family, has opened a window into a chimpanzee’s mind,” Goodall said.
Though previous efforts to teach chimps spoken languages had failed, the researchers believed there was a better chance using signs. But Washoe’s language skills were disputed by scientists who believed that language is unique to humans. Among those who doubted that chimps could use language were linguist (语言学家) Noam Chomsky and Harvard scientist Steven Pinker. They believed primates simply learn to perform certain acts in order to receive rewards, and do not acquire true language.
5. As for its first task, Washoe was involved with _______.
A. some space research
B. a study on African animals
C. an ASL project
D. the program of training the Air Force

C. questioned
D. discussed
8. What can be inferred from the passage?
A. The ASL project was first set up in Africa for the study on Washoe.
B. Washoe may communicate with other chimps by signing.
C. Washoe must have been able to speak 250 words or so.
D. The researchers will prove that most chimps could use language.
9. Which of the following is TRUE according to the passage?
A. Washoe was the first animal to be taught human language.
B. Washoe, the chimp, was named in honor of a place.
C. There were four chimps in total at Ellensburg Campus.

About ten years ago, a young and very successful businessman named Josh was traveling down a Chicago neighborhood street. He was going a bit too fast in his shiny, black, 12 cylinder Jaguar XKE, which was only two months old.
He was watching for kids rushing out from between parked cars and slowed down when he thought he saw something. As his car passed, no child came out, but a brick sailed out and — WHUMP! — it hit the Jag’s shiny black side door! SCREECH...!!!! Immediately Josh stopped the car, jumped out, seized the kid and pushed him up against a parked car. He shouted at the kid, "What was that all about and who are you? Just what the heck are you doing?!" Building up a head of steam, he went on. " That’s my new Jag, that brick you threw is gonna cost you a lot of money. Why did you throw it?"
"Please, mister, please....I’m sorry! I didn’t know what else to do!" begged the youngster. "I threw the brick because no one else would stop!" tears were streaming down the boy’s face as he pointed around the parked car. "It’s my brother, mister," he said. "He rolled of the curb (路沿) and fell out of his wheelchair and I can’t lift him up. "Sobbing, the boy asked the businessman," Would you please help me get him back into his wheelchair? He’s hurt and he’s too heavy for me.
Moved beyond words, the young businessman tried hard to swallow the rapidly swelling lump in his throat. Straining, he lifted the young man back into the wheelchair and took out his handkerchief and wiped the scrapers and cuts, checking to see that everything was going to be OK. He then watched the younger brother push him down the sidewalk toward their home.
It was a long walk back to the black, shining 12 cylinder Jaguar XKE — a long and slow walk. Josh never did fix the side door of his Jaguar.

A traveler was passing through a desert on a hot day. He was tired, feeling thirsty and hungry. At least, he needed a shady spot to rest for a while.
