Those who spend more pre-bedtime hours using the Internet or watching television are more likely to report insufficient sleep, even though they sleep almost as long as people spending fewer pre-bedtime hours in front of a computer or television screen, survey findings show.
“While many people use electronic media, say, the Internet, it should be noted that the longer media use before sleep can trigger (self-perceived) insufficient sleep,” lead researcher Dr Nakamori Suganuma, of Osaka University, Japan, told the reporter.
He and colleagues obtained data on self-perceived sleep problems and the use of electronic media prior to bedtime from 5,875 altogether Japanese respondents in two separate Internet-based surveys. Their findings are published in Sleep and Biological Rhythms.
Nearly half of the respondents associated their problem with electronic media use before bedtime. Longer electronic media users were also more likely to report insufficient sleep.
“Overall, 29% of light users (less than 1.5 hours) listed electronic media use as a possible cause of their insufficient sleep. By comparison, 40% of medium users (1.5 to 3 hours) and 54% of heavy users (more than 3 hours) said the same.
However, longer Internet and television use before bedtime did not correlate with less actual sleep.
While heavy users averaged about 3 more hours in front of computer or television screens than light users, the heavy users averaged only about 12 minutes less pre-workday sleep time than light users.
Notably, Suganuma said, "Internet use affected self-perceived insufficient sleep more than TV watching not only in younger Internet users but also in middle-aged or aged Internet users."
Up to 38% of the respondents listed accessing the Internet far into the night as a possible cause for their sleep disturbance, while about 25% said watching television far into the night caused it.
The findings suggest that while heavy computer and television use before bedtime has a small effect on sleep duration, it may have a more significant effect on "sleep demand and sleep quality," Suganuma notes. Heavy computer and television user before bed time are more likely to be______ than light ones.
| A．energetic | B．happy | C．sleepy | D．clever |

Going on holiday not only makes you feel good while you’re there, you also gain the health benefits for months, new research shows．
Jetting off to destinations such as the Maldives cuts your blood pressure, helps you sleep better and bounce back from stress, it found．The benefits last at least a fortnight longer than the vacation and can be felt for months in some cases where it is claimed．Experts say workers should always take their full holiday entitlement（权利）each year, but as many as one in three don’t．
The study compared key health markers in holidaymakers visiting Thailand, Peru or the Maldives, with people who stayed at home and continued working．The average blood pressure of those on holiday dropped by six percent while the workers saw their blood pressure rise by two percent over the same period．The sleep quality of holidaymakers improved by 17 percent while that of the non-holidaymakers deteriorated by 14 percent．
The study also found the ability of vacationers to recover from stress, known as the stress-resilience test improved by 29 percent．There was a 71 percent fall in stress resilience scores among workers．Tests showed a fall in blood glucose levels, reducing the risk of diabetes （糖尿病）, trimmer waistlines and improved mood and energy levels, with the effects sustained for at least two weeks after returning home．
The Holiday Health Experiment was conducted by tour operator Kuoni and Nuffield Health, the UK’s largest healthcare charity．According to the passage, how many people go on holiday?

Is the ‘Go to College’ Message Overdone?
Even in a weak job market, the old college try isn’t the answer for everyone. A briefing paper from the Brookings Institution warns that “we may have overdone the message” on college, senior fellow Isabel Sawhill said.
“We’ve been telling students and their families for years that college is the only way to succeed in the economy and of course there’s a lot of truth to that,” Ms. Sawhill said. “On average it does pay off… But if you load up on a whole lot of student debt and then you don’t graduate, that is a very bad situation.”
One comment that people often repeat among the years of slow job growth has been the value of education for landing a job and advancing in a career. April’s national unemployment rate stood at 7.5%, according to the Labor Department. The unemployment rate for high-school graduates over 25 years old who hadn’t attended college was 7.4%, compared with 3.9% for those with a bachelor’s degree or more education. The difference is even bigger among those aged 16-24. The jobless rate for those with only a high school diploma in that age group is about 20%. At the same time, recent research by Canadian economists cautions that a college degree is no guarantee of promising employment.
Ms. Sawhill pointed out that among the aspects that affect the value of a college education is the field of one’s major: Students in engineering or other sciences end up earning more than ones who major in the arts or education. The cost of tuition and the availability of financial aid are other considerations, with public institutions generally a better financial bargain than private ones.
She suggested two avenues for improving the situation: increasing vocational(职业的)-technical training programs and taking a page from Europe’s focus on early education rather than post-secondary learning. “The European countries put a little more attention to getting people prepared in the primary grades,” she said. “Then they have a higher bar for whoever goes to college—but once you get into college, you’re more likely to be highly subsidized(资助).”
She also is a supporter of technical training—to teach students how to be plumbers, welders and computer programmers—because “employers are desperate” for workers with these skills.People usually think that _____.
| A．the cost of technical schooling is a problem |
| B．one will not succeed without a college degree |
| C．technical skills are most important for landing a job |
| D．there is an increased competition in getting into a college |
What does the underlined part “taking a page from” mean?
| A．Hearing from. | B．Changing from. |
| C．Differing from. | D．Learning from. |
What can we infer from the passage?
| A．Public institutions charge more for education. |
| B．European universities are stricter with students. |
| C．Students with certain skills are in great demand. |
| D．Canadian students prefer to major in engineering. |
Ms. Sawhill may probably agree that _____.
| A．too much stress has been put on the value of college degrees |
| B．technical training is more important than college education |
| C．a college degree will ensure promising employment |
| D．it’s easier for art students to find favorite jobs |
The extraordinary Eastgate Building in Harare, Zimbabwe’s capital city, is said to be the only one in the world to use the same cooling and heating principles as the termite mound(白蚁堆).
Architect Mick Pearce used precisely the same strategy when designing the Eastgate Building, which has no air-conditioning and almost no heating. The building—the country’s largest commercial and shopping complex—uses less than 10% of the energy of a conventional building of its size. The Eastgate’s owners saved $3.5 million on a $36 million building because an air-conditioning plant didn’t have to be imported.
The complex is actually two buildings linked by bridges across a shady, glass-roofed atrium(天井) open to the air. Fans suck fresh air in from the atrium, blow it upstairs through hollow spaces under the floors and from there into each office through baseboard vents(通风口). As it rises and warms, it is drawn out via ceiling vents and finally exists through forty-eight brick chimneys.
During summer’s cool nights, big fans blow air through the building seven times an hour to cool the empty floors. By day, smaller fans blow two changes of air an hour through the building, to circulate the air which has been in contact with the cool floors. For winter days, there are small heaters in the vents.
This is all possible only because Harare is 1600 feet above sea level, has cloudless skies, little dampness and rapid temperature swings—days as warm as 31℃ commonly drop to 14℃ at night. “You couldn’t do this in New York, with its fantastically hot summers and fantastically cold winters,” Pearce said.
The engineering firm of Ove Arup&Partners monitors daily temperatures. It is found that the temperature of the building has generally stayed between 23℃ and 25℃, with the exception of the annual hot period just before the summer rains in October and three days in November, when a doorkeeper accidentally switched off the fans at night. And the air is fresh—far more so than in air-conditioned buildings, where up to 30% of the air is recycled. Why was Eastgate cheaper to be built than a conventional building?
| A．It was designed in a smaller size. |
| B．No air conditioners were fixed in. |
| C．Its heating system was less advanced. |
| D．It used rather different building materials. |
What does “it” refer to in Paragraph 3?
| A．Fresh air from outside. | B．Heat in the building. |
| C．Hollow space. | D．Baseboard vent. |
Why would a building like Eastgate Not work efficiently in New York?
| A．New York has less clear skies as Harare. |
| B．Its dampness affects the circulation of air. |
| C．New York covers a larger area than Harare. |
| D．Its temperature changes seasonally rather than daily. |
The data in the last paragraph suggests Eastgate’s temperature control system_____.
| A．allows a wide range of temperatures |
| B．functions well for most of the year |
| C．can recycle up to 30% of the air |
| D．works better in hot seasons |

In the 19th century, there used to be a model of how to be a good person. There are all these torrents of passion flowing through you. Your job, as captain of your soul, is to erect dams to keep these passions in check. Your job is to just say no to laziness, lust, greed, drug use and the other sins.
These days that model is out of fashion. You usually can’t change your behavior by simply resolving to do something. Knowing what to do is not the same as being able to do it. Your willpower is not like a dam that can block the torrent of self-indulgence. It's more like a muscle, which tires easily. Moreover, you're a social being. If everybody around you is overeating, you’ll probably do so, too.
The 19th-century character model was based on an understanding of free will. Today, we know that free will is bounded. People can change their lives, but ordering change is not simple because many things, even within ourselves, are beyond our direct control.
Much of our behavior, for example, is guided by unconscious habits. Researchers at Duke University calculated that more than 40 percent of the actions we take are governed by habit, not actual decisions. Researchers have also come to understand the structure of habits—cue, routine, reward.
You can change your own personal habits. If you leave running shorts on the floor at night, that'll be a cue to go running in the morning. Don’t try to ignore your afternoon snack craving. Every time you feel the cue for a snack, insert another routine. Take a walk.
Their research thus implies a different character model, which is supposed to manipulate the neural networks inside.
To be an effective person, under this model, you are supposed to coolly examine your own unconscious habits, and the habits of those under your care. You are supposed to devise strategies to alter the cues and routines. Every relationship becomes slightly manipulative, including your relationship with yourself. You're trying to arouse certain responses by implanting certain cues.
This is a bit disturbing, because the important habitual neural networks are not formed by mere routine, nor can they be reversed by clever cues. They are burned in by emotion and strengthened by strong yearnings, like the yearnings for admiration and righteousness.
If you think you can change your life in a clever way, the way an advertiser can get you to buy an air freshener, you’re probably wrong. As the Victorians understood, if you want to change your life, don’t just look for a clever cue. Commit to some larger global belief.Which of the following is the first-to-none element in the 19th-century character model?
| A．Action. | B．Capacity. | C．Resolution. | D．Enthusiasm. |
The research at Duke University indicated that ________
| A．One’s behavior is tough to change. |
| B．Habit has an unidentified structure. |
| C．Habit plays a vital role in one's behavior. |
| D．Both habit and will power are of significance. |
According to the new character model, personal behavior could be altered through
| A．techniques to break old routines. |
| B．techniques to provide different physical cues. |
| C．cues to change all the former unconscious habits. |
| D．cues to manipulate the habitual neural responses. |
