He has been doing this since age 8.“ At first, I was scared to d

The first time he wore his train pajamas to the track, Keegan went from last place to ninth place. He decided they brought luck. Since then, he has won a series of championships.Passion for

He knows what it means to have seats and roll cages built to fit his sons body.What I see in Keegan is passion, like how I feel about car restoration. But for him, everything has to align itself. I tell my so

More importantly, you have to have the right name, you have to look the correct way, speak the correct way, and act the correct way. Then the rest of it is really luck, like the stock market. If you dont put yours

18、volunteer hoursCWe 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 growing number of cyclists, however, brings this question to mind: should bicyclists b
19、e 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 register and license their vehicles to ensure accountability (责任）。 Bicyclists who use public
20、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 roadways. It seems only reasonable to ask bicyclists to contribute to transportation fu
21、nding 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 number and report their offenses (违法行为）。 This isnt true for bicyclists. Ive seen bicyclists
22、 moving quicklybetween 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 simple act of making bicyclists identifiable would encourage safer, more responsible riding.
23、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? Obviously, the city could determine an age when cycling would be considered a means of tran
24、sportation 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 displaying a license number could be simple.Many U.S. cities and towns now implement bike registr
25、ation 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 hoping for riders who take their responsibilities seriously.8. To advocate responsible cycling, the auth

Early diagnosis is crucial for patients to benefit from the few therapies available. But no scans ca
30、n 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 interest in developing artificial intelligence to identify Alzheimers based on brain imaging.Researchers at the University of
31、California, San Francisco, have now successfully trained an AIalgorithm(算法） to recognize one of the early signs of Alzheimers-a reduction in the brains glucose（葡萄糖） consumption-in positron emission tomography (PET) imaging.The algorithm accurately predicted an eventual Alzheimers diagnosis in nearly
32、 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 images of metabolism(新陈代谢）。circulation and other cellular activities. PET is well suited for an AI diagnostic tool because Alzheimers lea
33、ds 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. These changes are very hard for radiologists to pickup, he notes.The algorithm was trained and tested on 2,100 PET brain images fro
34、m about 1,000 people 55years and older. The images came from a 12-year study that tracked people who would ultimately be diagnosed with Alzheimers, as well as those with mild memory declines and healthy control participants. The algorithm was trained on 90 percent of the data and tested on the remai
35、ning 10percent. 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 81 percent of the patients in the first test group and 100 percent in the second who would be diagnosed with Alzheimers six yea
36、rs later, on average. The findings were published in February in Radiology.The algorithm is based on deep learning ,a machine-learning technique that uses artificial neural networks programmed to learn from examples. This is one of the first promising, preliminary(初步的）applications of deep learning t

Deep learning has been widely applied in diagnosing Alzheimers.C. To detect Alzheimers in its earliest stages calls for more exploration.D. Whether to use the model to detect Alzheimers remains a critical issue.参考答案1. B 2. C 3. A4. D 5. A 6. B 7. A 8. C 9. C 10. D 11.B 12. B 13. D 14. D 15. C
