After years of hearing drivers complain about scratches on their cars, Japan's Nissan Motor Company has officially announced the next big thing---a paint that not only resists scratches and scrapes, but actually repairs itself within a few days.

The new material, developed by Nippon Paint Company, contains an elastic rubbery-like resin(弹性树脂) that is able to heal minor marks caused by car wash equipment, parking lot encounters, road debris (石头碎片) or even on-purpose destruction. The automaker admits its results vary depending on the temperature and the depth of the damage, but adds this is the only paint like it in the world, and tests prove it works. Minor scratches, the most common type, are said to slowly fade over about a week. And once they're gone, there is no trace that they were ever there. The special paint is said to last for at least three years after it is first applied, but there is no word yet on whether more can be added after that period.

Nissan claims car washes are the worst offenders for this type of damage, accounting for at least 80 percent of all incidents. But the complete auto-healing won't come without scratching your wallet. The vehicle maker notes the special paint adds about $ 100 U.S. to the price of a car. It plans to use its new chemical mixture only on its X - Trail SUVs in Japan for now, as it looks for a more widespread presentation. And while plans to offer the feature overseas haven't been made yet, if it's a hit there, you can be almost sure market forces will drive it to these shores, as well.

1.From the article, we can find that_______.

A．the paint has already been used on cars by now

B．it beats other products of its kind in its lengthy effect

C．car damage is mainly caused by scratches and scrapes

D．marketing this paint in Europe is not under way

2.The paint used on cars can______.

A．last 3 years before it is re-applied again

B．fade only in a few days

C．help to protect cars from minor paint damage

D．reduce car scrape incidents to 20 percent

3.What can be inferred from the article?

A．The paint was developed by Nissan Motor Company.

B．The paint might work better in summer than in winter.

C．The mark on the car could disappear as soon as the paint is applied.

D．The paint is very popular in Japan.

 

Don't blame genes for aging facial skin. A new study of twins suggests you can   1   those coarse(粗糙的) wrinkles, brown or pink spots, and dilated(膨胀的) blood vessels on too much time in the sun, smoking, and being overweight.

Because twins share genes, but may have  2  exposures to environmental factors, studying twins allows an, "opportunity to control for genetic susceptibility(敏感性)," Dr. Elma D. Baron, at Case Western Reserve School of Medicine in Cleveland, Ohio, and colleagues  3  in the latest issue of Archives of Dermatology.

Their analysis of environmental skin-damaging factors in 65 pairs of twins hints that skin aging is  4  more to environment and lifestyle than  5   factors.

But when it   6   skin cancer, the researchers say their findings support previous reports that   7  environment and genes affect skin cancer risk.

Baron's team   8   facial skin of 130 twins, 18 to 77 years old, who lived  9   in the northern Midwest and Eastern regions of the U.S. who were  10   the Twins Days Festival in Ohio in August 2002.

At this time, each of the twins also  11    reported how their skin burned or tanned  12    sunscreen(防晒霜), their weight, and their history of skin cancer, smoking, and alcohol drinking.

The study group   13   of 52 fraternal and 10 identical twin pairs, plus 3 pairs who were unsure of their twin status. Identical(同卵的) twins share all of their genes and fraternal twins share only about half.

From these data, the researchers  14  strong ties, outside of twin status, between smoking, older age, and being overweight, and having facial skin with evidence of environmental  15 

 16   contrast, sunscreen use and drinking alcohol appeared correlated with   17    skin damage.

Baron and colleagues say the current findings, which highlight ties between facial   18  and potentially avoidable  19   factors -- such as smoking, being overweight, and   20   overexposure to the sun's damaging rays -- may help motivate people to minimize these risky behaviors.

WASHINGTON---At least four more U.S. air-traffic controllers are caught nodding off on the job at three separate airports across the nation, the government said Wednesday.

The controller working alone in the tower fell asleep and was out of communication for 16 minutes while a medical flight carrying a patient was trying to land at about 2 A.M. Wednesday at Reno-Tahoe International Airport in Nevada, the Federal Aviation Administration (FAA) said in a statement.

The FAA announced that it is also investigating a controller who fell asleep Monday at Boeing King County International Airport in Seattle and two controllers who were unresponsive at McGhee Tyson Airport in Knoxville, Tennessee on Feb.19.

“I am sick of this,” Senate Commerce, Science and Transportation Chairman Jay Rockefeller, a West Virginia Democrat, said in a statement. “We can’t have a system where some of the people responsible for safety are asleep at the switch.”

As the incidents pile up, sleep experts say it demonstrates that the agency faces a systemic issue with the thousands of people expected to work through the night in safety-critical jobs. Scientific research shows that workers on midnight shifts make more errors because it is so difficult for the body to adapt to sleeping during the day, they say.

The agency will add an extra controller at the 27 towers staffed with one worker on the midnight shift, the FAA statement said.

Representative John Mica, the Florida Republican who chairs the House transportation committee, criticized the decision to add controllers. “Only in the federal government would you double up on workers, averaging $161,000 per year in salary and benefits, that aren’t doing their job,” Mica said in a statement. Mica has pushed legislation that would allow as many as 90 smaller airports to switch from federal to private controllers.

“People have known these problems with fatigue（疲劳）have existed for years,” said John Goglia, a Boston-based aviation safety consultant. “They’re now showing up. The FAA is admitting they exist. Now the FAA needs to work on it.”

The four controllers in Nevada, Seattle and Texas have been suspended(暂时停职) during the investigations, the FAA said.

1.The underlined part “double up on workers” means “______”.

A．add two more workers	B．staff two workers at a post
C．settle two workers in a double room	D．give the workers double pay

2.According to John Goglia, fatigue problem ______.

A．is a known potential danger	B．has never appeared before
C．is common for day-time shift workers	D．seldom shows up at night

3.Which statement is true?

A．A controller fell asleep without communication for 16 minutes in Knoxville, Tennessee.

B．A medical flight carrying a patient failed to land with the controller asleep.

C．Jay Rockefeller pays little attention to sleeping at the switch.

D．Mica refused to support the decision to staff more controllers on the midnight shift.

4.We can infer from the passage that ______.

A．All the controllers in the US were working alone while they were on duty

B．The incidents are rooted in fatigue problems and those on midnight shifts need an extra nap

C．In the U.S. , thousands of people expect to work through the night in safety-critical jobs

D．The agency has added an extra controller at the 27 towers

 

It is obvious that doctors recognize obesity as a health problem. So why is it so hard for them to talk to their patients about it?
The results of two surveys, one of primary care physicians and the other of patients, found that while most doctors want to help patients lose weight and think it is their responsibility to do so, they often don’t know what to say.
“So while doctors may tell patients they are overweight, the conversation often ends there,” said Christine C. Ferguson, director of the Stop Obesity Alliance. “Patients are not told about the possibility of diabetes (糖尿病),” she said. “And doctors don’t feel they have good information to give. They felt that they didn’t have adequate tools to address this problem.
The lack of dialogue hurts patients, too. The patient survey, of over 1,000 adults, found that most overweight patients don’t even know that they’re too heavy. Only 39 percent of overweight people surveyed had ever been told by a health care provider that they were overweight.
Of those who were told they were obese, 90 percent were also told by their doctors to lose weight, the survey found. In fact most have tried to lose weight and may have been successful in the past—and many are still trying, the survey found. And many understand that losing even a small amount of weight can have a positive impact on their health and reduce their risk of obesity­related diseases like hypertension and diabetes.
Dr. William Bestermann Jr., medical director of Holston Medical Group, in Kingsport, Tenn. , which ranks the 10th in obesity among metropolitan areas in the United States, said the dialogue had to be an ongoing one and could not be dropped after just one mention of the problem. “If you’re to be successful with helping your patients lose weight, you have to talk to them at actually every visit about their progress, and find something to encourage them and coach them,” he said.
He acknowledged that many doctors tend to be not optimistic.
“Part of this is that there’s this common belief, and doctors are burdened by it, too, that overweight people are weak-willed and just don’t have any willpower and are self­indulgent and all that business,” he said. “If you think that way, you’re not going to spend time having a productive conversation.”
【小题1】What is the Stop Obesity Alliance most probably in Paragraph 3?

A．An organization of doctors suffering from obesity.

B．An organization of patients suffering from obesity.

C．A research group that conducts special surveys about overweight people.

D．A research group dealing with doctor-patient relationship.

【小题2】How many of the patients surveyed have been advised by their doctors to lose weight?

C．About 900.	D．About 1,000.

【小题3】What can be inferred about obesity patients in Paragraph 5?

A．They are not as hopeless as doctors think they are.

B．Most of them have tried hard to lose weight, but in vain.

C．Without their doctors’ constant coaching, there is little chance of their succeeding in losing weight.

D．Most of them have just given up their hope of becoming less heavy.

【小题4】According to the passage, which factor contributes to the lack of dialogue between doctors and patients?

A．Most doctors never think of warning their patients about their weight problem.

B．Many doctors find it difficult to persuade overweight people to lose weight.

C．Most patients are too weak-willed to do anything about their weight.

D．Many patients tend not to trust their doctors about their weight problem.
