32、 to be more creative C. promote awareness of world affairs D. instruct teens to earn volunteer hours C We are fortunate to live in a city that encourages bicycling as a means of transportation. Our local government has promoted bicycling by improving bike lanes and increasing the number of them. The
33、 growing number of cyclists, however, brings this question to mind: should bicyclists be required to share the responsibilities of the road? Automobile drivers have to take competency tests, follow established regulations, and accept punishment for breaking rules. The city requests drivers to regist
34、er and license their vehicles to ensure accountability (责任）。 Bicyclists who use public roadways should be held accountable, too. Lets look at what sharing the road means. For one thing, it should involve cost sharing. Auto registration and license fees are used, in part, for building and maintaining
35、 roadways. It seems only reasonable to ask bicyclists to contribute to transportation funding as well. More importantly, sharing the road includes accountability. When drivers ignore the rules of the road, the police and other motorists have the opportunity to identify them by their license plate nu
36、mber and report their offenses (违法行为）。 This isnt true for bicyclists. Ive seen bicyclists moving quickly between lanes. Because they show no identification, they feel protected by anonymity(匿名）。What good would it do to report to the police “I saw a guy on a red bike blow through the stoplight? The s
37、imple act of making bicyclists identifiable would encourage safer, more responsible riding. Of course, Ive heard arguments against asking cyclists to register and license their bikes. Some people might say, “Little kids ride bikes. Would you require a six-year-old rider to take a test and pay a fee?
38、 Obviously, the city could determine an age when cycling would be considered a means of transportation on public roads. Other people argue that bicycle fees are unfair because bikes dont damage the roadways as cars do. Bicycle registration fees could be comparatively modest, and the method for displ
39、aying a license number could be simple. 6 / 12 Many U.S. cities and towns now implement bike registration and licensing. A statute(法规）from one. California town states that the laws regulating bicycles have a dual purpose, antitheft and safety. Im eager to see more bicyclists on the road, and Im hopi

D Alzheimers AI An estimated 5.7 million people in the U.S. have Alzheimers disease-the most common type of dementia(痴呆） and that number is expected to mor
44、e than double by 2050. Early diagnosis is crucial for patients to benefit from the few therapies available. But no scans can deliver a conclusive diagnosis while a person is alive; instead doctors have to conduct numerous and complicated clinical and neuropsychological tests. So there is growing int
45、erest in developing artificial 7 / 12 intelligence to identify Alzheimers based on brain imaging. Researchers at the University of California, San Francisco, have now successfully trained an AI algorithm(算法） to recognize one of the early signs of Alzheimers-a reduction in the brains glucose（葡萄糖）cons
46、umption-in positron emission tomography (PET) imaging. The algorithm accurately predicted an eventual Alzheimers diagnosis in nearly all the test cases, according to the study. In PET imaging, a very small amount of a radioactive compound are injected into the body, producing three-dimensional image
47、s of metabolism(新陈代谢）。circulation and other cellular activities. PET is well suited for an AI diagnostic tool because Alzheimers leads to subtle changes in the brains metabolism that begin years before neural(神经的） tissue starts to go downhill, says study co-author Jae Ho Sohn, a radiologist at UCSF.
48、 These changes are very hard for radiologists to pick up, he notes. The algorithm was trained and tested on 2,100 PET brain images from about 1,000 people 55 years and older. The images came from a 12-year study that tracked people who would ultimately be diagnosed with Alzheimers, as well as those
49、with mild memory declines and healthy control participants. The algorithm was trained on 90 percent of the data and tested on the remaining 10 percent. It was then retested on a second, independent data set from 40 patients monitored for 10 years. The algorithm was highly sensitive and was able to recognize 8
