16、 new alcohol detection system could be introduced in cars by 2020, preventing intoxicated(喝醉的)drivers from starting their cars. The National Highway Traffic Safety Administration showcased their first prototype of the Driver Alcohol Detection System for Safety, known as “DADSS“ at Mothers Against Dr
17、unk Drivings 2015 1conference in Washington. The system prevents drivers from driving if they have 2over the recommended level of alcohol to drive safely by analyzing a drivers blood alcohol content(BAC)in two ways, with results 3less than a second to come through. A breathalyzer, which is placed on
18、 both sides of the steering wheel, will take a sample of the drivers 4breath, analyzing its alcohol content and the drivers blood alcohol levels will also be 5by shining an infrared(红外线的)light onto their fingertip when its placed on the cars ignition button. If the system detects that the driver is
19、over the limit, the car shuts down, preventing the driver starting the car. Speaking at the conference, NHTSA administrator Mark Rosekind said: “DADSS has enormous potential to prevent drunk driving in specific 6such as teen drivers and commercial fleets, and making it an option 7to vehicle owners.
20、It would provide a powerful new tool in the battle against drunk driving deaths.“ There are however some 8The DADSS system will not be compulsory in all cars and will also cost drivers around $ 400 to install in their cars. The system has also been met with some 9. Managing director of The American

Twice as many students in Singapore are proficient in math as in the United States. A)“We know what it takes to compete for
23、 the jobs and industries of our time,“ President Obama said in his State of the Union address this year. “We need to out-innovate, out-educate, and out-build the rest of the world.“ Yet despite the economic crisis facing the country, the US educational system remains frozen in place, unable to adapt
24、 to contemporary global realities. B)As all schoolchildren know, water freezes to solid, barren, cracked ice at 32 degrees Fahrenheit(华氏温度). So maybe it is more than a mere coincidence that 32 percent of US public and private-school students in the class of 2011 are deemed proficient in mathematics,
25、 placing the United States 32nd among the 65 nations that participated in the latest international tests administered by the Organization for Economic Cooperation and Development(OECD). The United States ranks between Portugal and Italy and far behind South Korea, Finland, Canada, and the Netherland
26、s. C)We became aware of the seriousness of the problem after we equated, with the help of colleagues, the test scores of the class of 2011 on the latest international test when this class was in 10th grade, with its prior eighth-grade scores on the National Assessment of Educational Progress(NAEP),
27、an official US test that both assesses performance of US students and sets the standard for “proficiency“. D)Linking these tests also allowed us to compare the performance of students in each state with that of students in other countries. The results are scary. Even in Massachusetts, with its famou
28、s collection of public and private schools, students reach only the level attained by students in the entire nations of Canada, Japan, and Switzerland. Massachusetts, the only US state with a majority of students(51 percent)above the proficiency mark, trails well behind students in South Korea and F
29、inland. E)The percentage proficient in the state of New York(30 percent)is equivalent to that achieved by students in debt-ridden Portugal and Spain. California, the home of highly skilled Silicon Valley, has a math proficiency rate of 24 percent, the same as bankrupt Greece and just a notch(等级)abov
30、e struggling Russia. F)President Obama, to his credit, has highlighted the problem repeatedly. But too many state education officials have done their best to obfuscate(故意混淆)the low performance of their students. Under the educational accountability rules set down by the federal law No Child Left Beh
31、ind, each state may set its own proficiency standard, and most have set their standards well below the world-class level. As a result, most state proficiency reports grossly increase the percentage of students who are proficient, if we account for the fact that our students need to compete not just
32、with others from the same state but also with those across the globe. G)When not obfuscating the problem, apologists explain away the results with misleading arguments. Some point to the countrys large immigrant and disadvantaged populations, which, to be sure, do pose difficult educational challeng
33、es. Proficiency rates among African-Americans and Hispanics are very low(11 and 15 percent, respectively). But if one compares only the white students in the US with all students in other countries, the US still falls short: Only 42 percent are proficient, which would place them at 17th in the world
34、 compared with all of the students in other nations. The only positive sign is the majority of Asian students in the United States(52 percent)who score at or above the proficiency level. H)When our results were first released, one school-board member in Loudoun County, a wealthy suburb of Washington
35、 D.C., explained away the results: “In many countries, poor-performing children are filtered out of high school, whereas in the US, we test all our students, both great and not so great. So the comparison is not on a level playing field.“ That might have been true some decades ago when only a few co
36、untries followed the United States emphasis on universal education and thus left many students out of school and unavailable for testing. But today the US actually graduates fewer students from high school than the average developed country, completely eliminating any claim that the US is testing a
37、broader range of the youth population. I)Some also take false comfort in the belief that it takes only a limited number of high-flying students to fill the jobs at Google, Facebook, IBM, and all the other businesses and professions that need highly skilled talent. The United States is still great at
38、 producing the advanced students needed to power economic growth. J)Still others say the low math scores are offset by a better record in reading. Admittedly the proficiency rate in only 10 countries is significantly higher than in the US. If not the world leader, the United States record is at leas
39、t better than average. Nonetheless, the set of skills most needed for sustained growth in economic productivityand the skills in shortest supply todayare those rooted in math competencies. Our future scientists and engineersthe engine of US innovationcome from those with high math skills. While Sili
40、con Valley could possibly be fueled by importing skilled workers from abroad, we should not continue to count on this in todays globalized world. Even if we could, it is hardly fair to our own young people to count them out of the countrys best jobs. K)According to our best calculations, the US coul
41、d enjoy a remarkable increase in its annual per capita GDP growth by enhancing the math proficiency of its students. Increasing the percentage of proficient students to the levels attained in Canada and South Korea would increase the annual US growth rate by 0. 9 percentage points and 1.3 percentage
42、 points, respectively. L)When translated into dollar terms according to the historical patterns, we see very different futures for the United States, depending on whether or not our schools are improved. If one calculates increases in national income from projections over an 80-year period(providing
43、 for a 20-year delay before any school reform is completed and newly proficient students begin their working careers), the present value of gains amounts to some $75 trillion for reaching the performance levels of Canada. These additions can be compared with our current GDP of $15 trillion or the $1
44、 trillion spent to stimulate the economy out of recession. M)It is easy for political leaders to put off considerations of effective school reform. The economic benefits from reform would not be felt immediately, as it takes time for an educated generation to become a productive workforce. But just
45、as the continuing debt crisis, if not fixed, will be out of control only over the longer term, so the best available solution to that crisisa fully unfrozen, high-functioning, constantly improving educational systemcould raise the level of human capital to the point where resources would be availabl
46、e to address much of this future debt crisis. In the simplest terms, the approaching financial crises with Social Security and Medicare are most effectively dealt with by enhanced growth of the economy, growth that will not be achieved without a highly skilled workforce.（分数：20.00）(1).One school-board member in Loudoun County excused the low ranking of the US by saying that poor-performing children were not filtered out of high school.（分数：2.00）填空项 1:_(2).Though President Ob
