Japan is a case in point. It has reduced automobile crashes on some roads by nearly 75 percent using a simple optical illusion. Bent stripes, called chevrons (人字形), painted on the roads make drivers think that they are driving faster than they really are, and thus drivers slow down.
Now the American Automobile Association Foundation for Traffic Safety in Washington D.C. is planning to repeat Japan’s success. Starting next year, the foundation will paint chevrons and other patterns of stripes on selected roads around the country to test how well the patterns reduce highway crashes.
Excessive speed plays a major role in as much as one fifth of all fatal traffic accidents, according to the foundation. To help reduce those accidents, the foundation will conduct its tests in areas where speed-related hazards are the greatest—curves, exit slopes, traffic circles, and bridges.
Some studies suggest that straight, horizontal bars painted across roads can initially cut the average speed of drivers in half. However, traffic often returns to full speed within months as drivers become used to seeing the painted bars.
Chevrons, scientists say, not only give drivers the impression that they are driving faster than they really are but also make a lane appear to be narrower. The result is a longer lasting reduction in highway sped and the number of traffic accidents.
第26题：The passage mainly discusses ________.
A) a new way of highway speed control
B) a new pattern for painting highways
C) a new approach to training drivers
D) a new type of optical illusion
Passage Three
Questions 31 to 35 are based on the following passage.
“Humans should not try to avoid stress any more than they would shun food, love or exercise.” Said Dr. Hans Selye, the first physician to document the effects of stress on the body. While here’s on question that continuous stress is harmful, several studies suggest that challenging situations in which you’re able to rise to the occasion can be good for you..
In a 2001 study of 158 hospital nurses, those who faced considerable work demands but coped with the challenge were more likely to say they were in good health than those who felt they stress that you can manage also boost immune(免疫的) function. In a study at the Academic Center for Dentistry in Amsterdam, researchers put volunteers through two stressful experiences. In the first, a timed task that required memorizing a list followed by a short test, subjects through a gory(血淋淋的) video on surgical procedures. Those who did well on the memory test had an increase in levels of immunoglobulin A, an antibody that’s the body’s first line of defense against germs. The video-watchers experienced a downturn in the antibody.
Stress prompts the body to produce certain stress hormones. In short bursts these hormones have a positive effect, including improved memory function. “They can help nerve cells handle information and put it into storage,” says Dr. Bruce McEwen of Rockefeller University in New York. But in the long run these hormones can have a harmful effect on the body and brain.
“Sustained stress is not good for you,” says Richard Morimoto, a researcher at Northwestern University in Illinois studying the effects of stress on longevity ,”It’s the occasional burst of stress or brief exposure to stress that could be protective.”
第31题：The passage is mainly about ________.
A．the benefits of manageable stress
B．stay away from
C．run out of
D．put up with
The so-called cloud forests of Monteverde lie along the crest of Costa Rica's Cordillera de Tilaran mountains. These habitats rely on the almost perpetual fog that forms as moisture-laden Caribbean winds rise up the eastern slopes of the mountains and pass through altitudes at which clouds condense, says Robert O. Lawton, an ecologist at the University of Alabama in Huntsville. The humidity in those breezes is enhanced by moisture expelled from the leaves of lowland forests.
By the early 1990s, more than a century of deforestation had left only 18% of the Costa Rican lowland forests east of the peaks untouched. The pastures that replaced forests don't humidify the winds as well as forests do and are better at warming the atmosphere. As a result, the winds off these pastures must rise further up the Cordillera de Tilaran slopes before clouds condense.
Satellite photos of the lowlands in the dry season show that clouds are absent or sparse over deforested areas but are thicker over the forests of neighboring Nicaragua. Computer simulations of day-time cloud formation in the area support these observations, Lawton notes, and they also suggest that the altitude of the cloud base would rise about 200m above today's height if the lowlands were completely deforested. Lawton and his colleagues report their result in Science magazine.
The gradual shifting of bird ranges upslope and a recent population crash among frogs and toads in the Monteverde cloud forest suggest that the veil of clouds may be lifting. Scientists had already blamed the rise of the cloud base for the longer periods of mistfree conditions observed at the downwind edge of the forest. Lawton warns that in the future, the clouds may disappear from the Monteverde slopes for days at a time during the dry season -- a development that could lead to collapse of the ecosystems there.
The passage mainly discusses ______.
A．large-scale deforestation and the climate changes
B．ecosystems in the eastern lowlands
C．the cloud forests of Monterverde
D．Caribbean winds
