10、B, C or D. Mark your answers on the ANSWER SHEET. (40 points)Text 1Among the annoying challenges facing the middle class is one that will probably go unmentioned in the next presidential campaign: What happens when the robots come for their jobs?Dont dismiss that possibility entirely. About half of
11、U.S. jobs are at high risk of being automated, according to a University of Oxford study, with the middle class disproportionately squeezed. Lower-income jobs like gardening or day care dont appeal to robots. But many middle-class occupations-trucking, financial advice, software engineering have aro
12、used their interest, or soon will. The rich own the robots, so they will be fine.This isnt to be alarmist. Optimists point out that technological upheaval has benefited workers in the past. The Industrial Revolution didnt go so well for Luddites whose jobs were displaced by mechanized looms, but it
13、eventually raised living standards and created more jobs than it destroyed. Likewise, automation should eventually boost productivity, stimulate demand by driving down prices, and free workers from hard, boring work. But in the medium term, middle-class workers may need a lot of help adjusting.The f
14、irst step, as Erik Brynjolfsson and Andrew McAfee argue in The Second Machine Age, should be rethinking education and job training. Curriculums from grammar school to college- should evolve to focus less on memorizing facts and more on creativity and complex communication. Vocational schools should
15、do a better job of fostering problem-solving skills and helping students work alongside robots. Online education can supplement the traditional kind. It could make extra training and instruction affordable. Professionals trying to acquire new skills will be able to do so without going into debt.The
16、challenge of coping with automation underlines the need for the U.S. to revive its fading business dynamism: Starting new companies must be made easier. In previous eras of drastic technological change, entrepreneurs smoothed the transition by dreaming up ways to combine labor and machines. The best
17、 uses of 3D printers and virtual reality havent been invented yet. The U.S. needs the new companies that will invent them.Finally, because automation threatens to widen the gap between capital income and labor income, taxes and the safety net will have to be rethought. Taxes on low-wage labor need t
18、o be cut, and wage subsidies such as the earned income tax credit should be expanded: This would boost incomes, encourage work, reward companies for job creation, and reduce inequality.Technology will improve society in ways big and small over the next few years, yet this will be little comfort to t
19、hose who find their lives and careers upended by automation. Destroying the machines that are coming for our jobs would be nuts. But policies to help workers adapt will be indispensable.21.Who will be most threatened by automation?A Leading politicians.BLow-wage laborers.CRobot owners.DMiddle-class

The implication is that Millennials prefer news from the White House to be filtered through other source, Not a presidents social media platform.Most Americans rely on social media to check daily headlines. Yet as distrust has risen toward all media, people may be starting to beef up
24、 their media literacy skills. Such a trend is badly needed. During the 2016 presidential campaign, nearly a quarter of web content shared by Twitter users in the politically critical state of Michigan was fake news, according to the University of Oxford. And a survey conducted for BuzzFeed News foun
25、d 44 percent of Facebook users rarely or never trust news from the media giant.Young people who are digital natives are indeed becoming more skillful at separating fact from fiction in cyberspace. A Knight Foundation focus-group survey of young people between ages 14and24 found they use “distributed

35、解决。菜单:TS工具文字多行输入(文字多行输入)点取菜单后,出现图 29所示对话框:对话框的第一行是一排按钮,用于输入钢筋直径和角标等特殊符号;在第二行的编辑框中,我们可以很方便的对文字高度、行间距和每行的字符数进行调整,从而达到排版的目的;最右侧的一排按钮可以对文字进行增强处理:图 29多行文字输入例如,我们在结构中经常需要写一些“构造要求”,但这些文字在AutoCAD中不方便排版;这时,我们可以先把“构造要求”用记事本等工具写好后保存起来。然后点取文件导入功能,屏幕出现图 30所示对话框,选择已经写好的文本文件,如x:tssd14samplebeam.txt,然后点取打开按钮,文件中的内容
36、就会被传入到多行文字输入的编辑框里面来;我们进行相关调整后点取确定按钮,命令行出现提示:图 30文件导入请选取文字插入点:点取图 31中P1点图 31文字说明这样,我们的文字说明就写好了,如果您对输出的结果仍不满意,还可以用多行编辑对已有文字反复进行调整。下面,我们把本图的名称添加上去,这样,这张图形看起来就更加完整了。2. 图形名称菜单:TS工具符号图形名字(符号图形名字)点取菜单后,出现图 32所示对话框;在填写好相关内容后,点取插入按钮,这时命令行出现提示:图 32图形名称选取文字插入点:点取图 31中P2点完成后洀渀漀瀀焀爀猀琀甀瘀眀砀礀稀笀簀紀縀缀耀脀舀茀萀蔀蘀蜀蠀褀言謀谀贀踀輀退鄀鈀錀鐀销阀需頀餀騀鬀鰀鴀鸀鼀一伀倀儀刀匀吀唀嘀圀堀夀娀嬀尀崀帀开怀愀戀挀搀攀昀最栀椀樀欀氀洀渀漀瀀焀爀猀琀甀瘀眀砀礀稀笀簀紀縀缀耀脀舀茀萀蔀蘀蜀蠀褀言謀谀贀踀輀退鄀鈀錀鐀销阀需頀餀騀鬀鰀鴀鸀鼀一伀倀儀刀匀吀唀嘀
