In the near future, we may be using our eyes to operate our smart-phones and tablets, even when it comes to playing popular games like Fruit Ninja.
The Gaze Group has been developing eye-controlled computer technology for nearly 20 years. But those devices have been firstly designed to help those with disabilities, and are very expensive.
“After a while, we figured out that probably the best way is to go for a mass-market way,” says Gaze’s Sune Alstrup Johansen. “where everybody would have this available."
Johansen and some of his colleagues have formed a new company, the Eye Tribe, which is hoping to develop the technology on a mass commercial level.
The technology works with the help of the computing device toward the user’s face. After making sure of the user’s eye movements, the technology is then able to easily find where a person’s eyes are moving, and then allow the eyes to control a cursor(光标).
“Our software can then determine the location of the eyes and know where you’re looking on the screen to make sure what you’re looking at, ” reads an explanation on the Eye Tribe site.
There has been a gradual change toward hands-free technology in recent years, particularly in the gaming world. Recently Xbox released the Kinect device, which lets users control their Xbox and play certain games using only their hands, legs and voices. But still, most of these devices have been more of a gimmick than a practical way to use one’s hands to control a mobile device. Johansen said a replaceable filter(滤光器)would be a cheap, convenient way for most consumers.
And even as companies like The Eye Tribe work to create such a product for the average user, making the eye-controlled technology more accessible and less expensive will have similar benefits for physically disabled users.

举一反三
Today, there are many chances for those who wish to continue their education. However, nearly all require some break in one’s career in order to attend school full time.
Part-time education, that is, attending school at night or for one weekend a month, tends to drag the process out over time and puts the completion of a degree program out of reach of many people. Additionally, such programs require a fixed time commitment which can also impact negatively on one’s career and family time.
Of the many approaches to teaching and learning, however, perhaps the most flexible (灵活的) is that called distance learning. Distance learning is an educational method which allows the students the flexibility to study at his or her own pace to achieve the academic goals which are so necessary in today’s world. The time required to study may be set aside at the student’s convenience. Additionally, the student may enroll in distance learning courses from actually any place in the world, while continuing to pursue their chosen career. Individual assistance may be available via regular airmail, telephone, fax machine, teleconferencing and over the Internet.
Good distance learning programs are characterized by the inclusion of a subject evaluation tool with every subject, so a student doesn’t need to travel away from home to take a test. Another characteristic of a good distance learning program is the equivalence (等同) of the distance learning course with the same subject materials as those students taking the course on the home campus. The resultant diploma or degree should also be the same whether distance learning or on-campus study is employed. The individuality of the professor/student relationship is another characteristic of a good distance learning program. In the final analysis, a good distance learning program has a place not only for the individual student but also the company or business that wants to work in partnership with their employees for the educational benefit, professional development, and business growth of the organization. Supporting distance learning programs for their employees gives the business the advantage of retaining (留住) career-minded people while contributing to their personal and professional growth through education.
小题1:According to the passage, which of the following is NOT a disadvantage of part time education?| A．It requires some break in one’s career. | | B．It tends to last too long for many people to complete a degree program. | | C．It affects one’s career. | | D．It gives the student less time to share with the family. |
小题2: Which of the following is NOT an advantage of distance learning? | A．The student may choose his or her own pace. | | B．The student may study at his or her convenience. | | C．They can pursue their chosen career while studying. | | D．Individual assistance comes through regular airmail, telephone and fax machine. |
小题3:What benefit will distance learning program bring to a business? | A．Attracting more talented people. | | B．Good image of the business. | | C．Better cooperation with universities. | | D．Further training of employees and business growth. |

Online Degrees
Today, you can earn a degree from a major university without ever having sat in one of their classrooms. Many colleges and universities are offering online courses and degree programs now.
Online Learning Programs
With a computer and an Internet connection, you can earn a degree from home, work, or anywhere else for that matter. Online degree programs follow much the same routines as traditional learning, with a few twists. There are lectures, but they won"t be in person. There are assignments (作业) , but you won"t hand them to your instructor. In most situations, you are free to "go to class" when it fits your"schedule. If you get a phone call during class, you don"t have to miss anything. If you get sick, you don"t have to ask for someone"s notes, and you just visit the lecture later.
You"ll communicate with your instructor by e-mail, chat room and instant messaging. Your classroom will live in a special software program. Contrary to popular belief, you will have close contact with other students and the instructor.
Evaluating the Program
There are a lot of questions to ask before you make your selection, such as:
How do students interact with each other?
★Online programs can use chat rooms, instant messaging, teleconferencing, and video conferencing to communicate. The key is to find a program that has this interaction built into it and even requires it.
★What kind of reputation does the school have?
It may seem simple-a good school will have a good online program. This reputation,however, may not be as straightforward as you think. It"s not uncommon for a great school to have a weak program or two. So you"d better look at the overall quality of the school and make a judgment.
The Employers" View
As more and more employees get online degrees and use them in the workforce(职场) , hiring managers will begin to feel more secure about the quality of education these people have.
小题1:In which way is online education special?| A．If you get sick, you"ll miss the lecture. | | B．There are lectures, but you don"t need to meet the lecturers. | | C．If you get a phone call during class, you will miss something. | | D．There are assignments, and you must hand them to your instructor. |

Baekeland and Hartmann report that the " short sleepers" had been more or less average in their sleep needs until the men were in their teens. But at about age 15 0r so, the men voluntarily began cutting down their nightly sleep time because of pressures from school, work, and other activities. These men tended to regard their nightly periods of unconsciousness as bothersome interruptions in their daily routines.
In general, these "short sleepers" appeared ambitious, active, energetic and cheerful. They stuck to their opinions, and were very sure about their job choices..They often held several jobs at once, or worked full-or part-time while going to school. And many of them had a strong urge to appear "normal" or " acceptable" to their friends and colleagues.
When asked to remember their dreams, the " short sleepers" did poorly. More than this, they seemed to prefer not remembering. Similarly, their usual way of dealing with psychological problems was not to admit that the problem existed, and then to keep busy in the hope that the trouble would go away.
The sleep patterns of the " short sleepers" were similar to, but less extreme than, sleep patterns shown by many mental patients categorized as manic (躁狂者).
The "long sleepers" were quite different indeed. Baekeland and Hanmann report that these young men have been lengthy sleepers since childhood. They seemed to enjoy their sleep, protected it, and were quite concemed when sometimes they didn"t have their desired 9 hours of nightly bed rest. They tended to remember their dreams much better than the " short sleepers". Many of the "long sleepers" were shy, anxious, quiet, nervous, passive, mildly depressed, and unsure of themselves ( particularly in social situations) . Several openly stated that sleep was an escape from their daily problems.
小题1:From the passage, we can leam that .| A．"short sleepers" need less sleep by nature | | B．"long sleepers" sleep a longer period of time during the day | | C．many "long sleepers" preserve their sleeping habit formed during their childhood | | D．many " short sleepers" have to reduce their nightly sleep time because of busy work |
小题2:Many "short sleepers" are likely to hold the view that _____.| A．sleep is a good way to escape from the reality | | B．sleep is not so important as their daily activities | | C．sleep affects their judgment on some important things | | D．sleep is the best way to deal with psychological troubles |
小题3: It can be learned from the passage that the"short sleepers" _____.| A．do not know how to relax properly | | B．are more unlikely to run into mental problems | | C．are full of energy even under the pressures of life | | D．often pay little attention to the consequences of inadequate sleep |
小题4: When sometimes they cannot enjoy adequate sleep, the "long sleepers" might ______.| A．appear disturbed | B．become energetic | | C．feel dissatisfied | D．be extremely unhappy |

Black Box
You never see them, but they"re with you every time you fly. They record where you"re going,how fast you"re traveling and whether everything on your airplane is functioning normally. Their ability to resist almost any disaster makes them seem like something out of a comic (漫画) book.They"re known as the black box.
When planes fall from the sky, as a Yemeni airliner did on its way to the Comoros Islands in the Indian Ocean on June 30, 2009, the black box is the best method for identifying what went wrong. So when a French submarine(潜水艇) discovered its homing signal five days later, it marked a huge step toward determining the cause of the disaster in which 152 passengers were killed.
In 1958. Australian scientist David Warren developed a flight-memory recorder that would track basic information like altitude and direction. That was the first model for a black box, which became a requirement on all US commercial flights by 1960. Early models often failed to resist crashes, however, so in 1965 it was completely redesigned. That same year, the Federal Aviation Authority required that the boxes, which were never actually black, be painted orange or yellow to be easier to see.
Modem airplanes have two black boxes: a voice recorder, which tracks pilots" conversations, and a flight-data recorder, which monitors fuel levels, engine noises and other operating functions that help experts reconstruct the aircraft"s final moments. The boxes can resist powerful force and temperatures up t0 2,OOOoF. They"re also able to send out signals from depths of 20,000 ft. Experts believe the boxes from Air France Flight 447 , which crashed near Brazil on June 1 , 2009 , are in water nearly that deep, but statistics say they"re still likely to turn up. In the approximately 20 deep-sea crashes over the past 30 years, only one plane"s black boxes were never recovered.
小题1:What can we leam about the black box from the passage?| A．It helps an airplane function normally. | | B．Its ability to avoid disasters is amazing. | | C．It is necessary equipment on an airplane. | | D．The idea for its design comes from a comic book. |
小题2:From the black box on the Yemeni airliner we can get information about _____.| A．the scene of the crash and the damage | | B．data for analyzing the cause of the crash | | C．the total number of passengers on board | | D．homing signals sent by the pilot before the crash |
小题3:The Federal Aviation Authority required the black boxes be painted orange or yellow to| A．make them easily identified | | B．meet the international standards | | C．caution people to handle them with care | | D．distinguish them from the color of the plane |
小题4:What do we know about the black boxes from Air France Flight 447?| A．They have stopped sending homing signals. | | B．They were destroyed somewhere near Brazil. | | C．There is an urgent need for them to be restructured. | | D．There is still a good chance of their being recovered. |

Retail therapy（购物疗法）has long been considered as a good way to let off stress. Now, US scientists have discovered not only does retail therapy exist，but that it could be caused by an individual"s fear of sudden death.
Researchers found materialistic people thought terrorism and war more stressful than others.
Psychologists believe the rise of materialism around the world and its treatment effect on extreme stress might be a response to fear of death caused by acts of terrorism, disease and natural disasters.
The scientists from Michigan State University said people with possession obsessions（妄想）often have lower self-esteem than others so are more likely to shop as the result of severe psychological suffering.
Ayalla Ruvio，a business professor studying people"s shopping habits while rockets fell in Israel, said, "When the going gets tough, the materialistic people go shopping. This stress spending is likely to produce even greater stress and lower well-being. Essentially, materialism appears to make bad events even worse.
Dr Ruvio led a two-part study of Israeli citizens living in a town that came under extreme rocket attacks for about six months in 2007. She compared 139 residents of the southern town with 170 from another town that was not under attack to see how their symptoms of post-traumatic stress and shopping habits varied. Dr Ruvio found that, when faced with a deadly threat, those who are highly materialistic suffered much higher levels of stress，while their tendency to shop was increased.
Dr Ruvio said, "The relationship between materialism and stress may be more harmful than commonly thought.”
The second stage of their research surveyed 855 Americans about their materialistic nature and fear of death. They found shopping was used to relieve feelings of stress and anxiety about death but this was in response to fear of a variety of life-threatening events like car accidents, criminal attacks and natural disasters.
小题1:Which of the following opinion is NOT right according to the text?| A．Terrorism is believed to easily cause the rise of materialism. | | B．The materialistic find terrorism and war more stressful than others. | | C．The scientists think possession obsessions help people get self-respect. | | D．The scientists think people with possession obsessions suffer a lot mentally. |
小题2:Why did Dr Ruvio choose to study the two groups of Israeli citizens mentioned in the passage?| A．They enjoy the special shopping culture. | | B．The stresses they face are usually deadly. | | C．They are in different situation in terms of war. | | D．They are usually active participants for researchers. |
小题3:What"s the result about Dr Ruvio"s research?| A．Impulsive spending does good to people"s health. | | B．Shopping can"t lower one"s stress as it is expected. | | C．Faced with great stress, people feel hopeless for life. | | D．Faced with threat，people"s wish to shop will decrease. |
小题4:Which of the following events threaten people"s life?
①Greater stress; ②Car accidents; ③Criminal attacks；. ④Natural disasters;小题5:What"s the main idea of the passage?| A．Greater stress can lead to shopping. | | B．Greater stress can cause a lot of diseases | | C．Shopping is very important in people"s life. | | D．Can shopping reduce the stress and relieve the fear of death? |
