American society is not nap (午睡)-friendly. In fact, says David Dinges, a sleep specialist at the University of Pennsylvania School of Medicine, “There’s even a prohibition against admitting we need sleep”. Nobody wants to be caught napping or found asleep at work. To quote a proverb: “Some sleep five hours, nature requires seven, laziness nine and wickedness eleven.”
Wrong. The way not to fall asleep at work is to take naps when you need them. “We have to totally change our attitude toward napping,” says Dr. William Dement of Stanford University, the godfather of sleep research.
Last year a national commission led by Dement identified an “American sleep debt” which one member said was as important as the national debt. The commission was concerned about the dangers of sleepiness: people causing industrial accidents or falling asleep while driving. This may be why we have a new sleep policy in the White House. According to recent reports, President Clinton is trying to take a ha1f-hour snooze (瞌睡) every afternoon.
About 60 percent of American adults nap when given the opportunity. We seem to have “a mid afternoon quiet phase,” also called “a secondary sleep gate.” Sleeping 15 minutes to two hours in the early afternoon can reduce stress and make us refreshed. Clearly, we were born to nap.
We Superstars of Snooze don't nap to replace lost shut-eye or to prepare for a night shift.Rather, we “snack” on sleep, whenever, wherever and at whatever time we feel like it. I myself have napped in buses, cars, planes and on boats; on floors and beds; and in libraries, offices and museums.It is commonly accepted in American society that too much sleep is .

Since the 1970s, scientists have been searching for ways to link the brain with computers. Brain-computer interface (BCI) technology could help people with disabilities send commands to machines.
Recently, two researchers, Jose Millan and Michele Tavella from the Federal Polytechnic School in Lausanne, Switzerland, demonstrated a small robotic wheelchair directed by a person's thoughts.
In the laboratory, Tavella operated the wheelchair just by thinking about moving his left or right hand. He could even talk as he watched the vehicle and guided it with his thoughts.
“Our brain has billions of nerve cells. These send signals through the spinal cord (脊髓) to the muscles to give us the ability to move. But spinal cord injuries or other conditions can prevent these weak electrical signals from reaching the muscles.” Tavella says. “Our system allows disabled people to communicate with external world and also to control devices.
The researchers designed a special cap for the user. This head cover picks up the signals from the scalp (头皮) and sends them to a computer. The computer interprets the signals and commands the motorized wheelchair. The wheelchair also has two cameras that identify objects in its path. They help the computer react to commands from the brain.
Prof. Millan, the team leader, says scientists keep improving the computer software that interprets brain signals and turns them into simple commands. “The practical possibilities that BCI technology offers to disabled people can be grouped in two categories: communication, and controlling devices. One example is this wheelchair.”
He says his team has set two goals. One is testing with real patients, so as to prove that this is a technology they can benefit from. And the other is to guarantee that they can use the technology over long periods of time.BCI is a technology that can ________.
| A．help to update computer systems |
| B．link the human brain with computers |
| C．help the disabled to recover |
| D．control a person's thoughts |
How did Tavella operate the wheelchair in the laboratory?
| A．By controlling his muscles. |
| B．By talking to the machine. |
| C．By moving his hand. |
| D．By using his mind. |
Which of the following shows the path of the signals described in Paragraph 5?
| A．scalp→computer→cap→wheelchair |
| B．computer→cap→scalp→wheelchair |
| C．scalp→cap→computer→wheelchair |
| D．cap→computer→scalp→wheelchair |
Which of the following would be the best title for the text?

Interest in pursuing international careers has risen in recent years strengthened by permanent personnel shortages that are causing companies to search beyond their home borders for talent.
Professionals seek career experience outside of their home countries for a variety of reasons. They may feel the need to recharge their batteries with a new challenge. They may want a position with more responsibility that encourages creativity. Or they may wish to expose their children to another culture, and the opportunity to learn a second language.
When applying for a job, one usually has to submit a resume or curriculum vitae (CV). The two terms generally mean the same thing: a one--or two--page document describing one's educational qualifications and professional experience. However, guidelines for preparing a resume are constantly changing. The best advice is to find out what is appropriate regarding the company culture, the country culture, and the culture of the person making the hiring decision. The challenge will be to include two or more cultures in one document. The following list is a good place to start.
"Educational requirements differ from country to country. In almost every case of 'cross--border' job hunting, just stating the title of your degree will not be an adequate description. Provide the reader with details about your studies and any related experience. "
Pay attention to the resume format you use-chronological or reverse-chronological order. Chronological order means listing your 'oldest' work experience first. Reverse-chronological order means listing your current or most recent experience first. Most countries have preferences about which format is most acceptable. If you find no specific guidelines, the general preference is for the reverse-chronological format. "
If you are submitting your resume in English, find out if the receiver uses British English or American English because there are changes between the two versions. For example, university education is often referred to as 'tertiary education' in the United Kingdom, but this term is almost never used in the United States. A reader who is unfamiliar with these changes may assume that your resume contains errors.Companies are hiring more foreign employees because ________.
| A．they find foreign employees are usually more talented |
| B．they need original ideas from employees hired overseas |
| C．they want to expand their business beyond home borders |
| D．they have difficulty finding qualified personnel at home |
The author believes that an individual who applies to work overseas ________.
| A．is usually creative |
| B．aims to improve his foreign language skills |
| C．is dissatisfied with his own life at home |
| D．seeks either his own or his children's development |
When it comes to resume writing, it is best to ________.
| A．take cultural factors into consideration |
| B．learn about the company's hiring process |
| C．follow appropriate guidelines for job hunting |
| D．know the employer's personal likes and dislikes |
When writing about qualifications, applicants are advised to __________.
| A．stress their academic potential to impress the decision maker |
| B．give the title of the university degree they have earned at home |
| C．provide a detailed description of their study and work experiences |
| D．emphasize their interest in pursuing a 'cross-border' career |
According to the author's last piece of advice, the applicants should be aware of ________.
| A．the different educational systems in the US and the UK |
| B．the differences between the changes of English |
| C．the receiver's preference with regard to the format |
| D．the special characteristics of American and British cultures |
There is a common belief among parents that schools are no longer interested in spelling. No school I have taught in has ever considered spelling unimportant as a basic skill. There are, however, quite different ideas about how to teach it, or how much priority (优先) it must be given over general language development and writing ability. The problem is how to encourage a child to express himself freely in writing without holding him back with spelling.
If spelling becomes the only point of his teacher's interest, clearly a bright child will be likely to "play safe". He will write only words within his spelling range. That's why teachers often encourage the early use of dictionaries and pay attention to content rather than technical ability.
I was once shocked to read on the bottom of a sensitive piece of writing about a personal experience: "This work is terrible! There are far too many spelling mistakes." It may have been a sharp criticism of the pupils' technical abilities in writing, but it was also a sad thing for the teacher who had omitted (略过)to read the composition, which contained some beautiful expressions of the child's deep feelings. The teacher was not wrong to draw attention to the mistakes, but if his priority had centered on the child's ideas, an expression of his disappointment with the presentation would have given the pupil more hope to seek improvement.Teachers differ in their opinions about _______ .
| A．the difficulties in teaching spelling |
| B．the necessity of teaching spelling |
| C．the importance of the basic writing skills |
| D．the role of spelling in general language development |
The expression "play safe" probably means ______.
| A．to write carefully |
| B．to avoid using words one is not sure of |
| C．to use dictionaries frequently |
| D．to do as teachers say |
Teachers encourage the use of dictionaries so that______.
| A．students will be able to express their ideas more freely. |
| B．teachers will have less trouble in correcting mistakes. |
| C．students will have more trust in writing. |
| D．students will learn to spell words correctly. |
The main idea of the passage is _______.
| A．the importance of developing writing skills |
| B．the importance of spelling |
| C．the correct way of marking composition |
| D．the relationship between spelling and the content of a composition |
The sea has always interested man. From it he can get food, minerals, and treasure. For thousands of years, he could sail on it. But he could not go far beneath its surface.
Man wants to explore deep into the sea. However, he is not a fish. He must breathe air, so he can't stay under the water's surface for any length of time. To explore deep water, man faces even more dangers and problems.
A diver who wants to stay under water for more than a few minutes must breathe air or a special mixture of gases. He can wear a diving suit and have air pumped to him from above. He can carry a tank of air on his back and breathe through a nose and a mouthpiece. Water weighs 800 times as much as air. Tons of water pushes against a diver deep in the sea. His body is under great pressure.
When a diver is under great pressure, his blood takes in some of the gases he breathes. As he rises to surface, the water pressure becomes less. If the diver rises too quickly, the gases in his blood form bubbles. The diver is then suffering from the bends. The bends can cause a diver to double up in pain. They can even kill him.On the whole, this passage is about ________.
| A．special mixtures of gases in deep sea |
| B．the problems man faces in deep sea diving |
| C．air pressure under the surface of sea water |
| D．a kind of illness that man suffers in the sea |
The passage does not say so, but it makes you think that ________.
| A．deep divers should be in good health |
| B．divers explore the deep sea only for treasure |
| C．diving under the water too quickly causes a kind of illness |
| D．there is a special mixture of gases under the sea |
From the passage we can see that ________.
| A．the sea began to interest man a few years ago |
| B．man is not at home deep in the sea |
| C．all divers will get the bends sooner or later |
| D．the air in the sea water will kill a diver if he is not careful |
