注：听音填空Believe in the Futureby Shi Zhi When cobwebs relentlessly clog my stove，When its dying smoke sighs for poverty,I will stubbornly ①dig out the disappointing ashes，And write with beautiful snowflakes: Believe in the Future。

When my overripe grapes melt into late autumn dew，When my fresh flower lies in another’s arms,I will stubbornly write on the bleak earth，With a dry frozen vine: Believe in the Future.I ②point to the waves billowing in the distance，I want to be the sea that holds the sun in its palm,Take hold of the beautiful warm pen of the dawn,And write with a child—like hand: Believe in the Future。

The reason why I believe so resolutely in the future is:I believe in the eyes of the future’s people，Their eyelashes that can brush away the ash of history，Their pupils that can see through the texts of time。

高考英语一轮复习Module1LifeintheFuture练习含解析外研版必修4080313Module 1 Life in the FutureⅠ.话题延读Over the next decade, technology will decimate more jobs in many professions.Some robots already cost less to operate than the salaries of the humans they replace, and they are getting cheaper.Boston Consulting Group predicts that, by 2025, the operating cost of a robot that does welding (焊接) will be less than $2 per hour, for example.That’s more affordable than the $25 per hour that a human welder earns today in America.Uber and many other companies are working on developing cars and trucks that don’t need a driver in the driver’s seat.According to the American Trucking Associations, approximately 3 million truck drivers were employed in the United States in 2010, and 6.8 million others were employed in other jobs relating to trucking activity.So roughly one of every 15 workers in the country is employed in the trucking business.We could be talking about millions of jobs disappearing in the early 2020s.And then there is the “Gig Economy (零工经济)” that has some businesses moving toward part-time, on-demand employment.Uber has already done this to taxi drivers, and other technology companies are doing it to a wide range of jobs.A study by INTUIT predicted that, by 2020, 40% of American workers will be self-employed, and that full-time jobs will be harder to find.We are talking about 60 million people in this category.The problem is that not only do such part-time workers lack reliable full-time jobs and sick pay, but they can’t enjoy health insurance and longer-term benefits.The measures to be taken are to raise trade barriers.But closing the doors to foreign trade won’t bring jobs back.It will only slow the global economy and hurt American exports, shrinking the U.S.economy and accelerating job loss.1.The underlined word “decimate” in Paragraph 1 can be replaced by “”.A.make someone interested inB.equip someone forC.wipe outD.bring back2.What will happen with technologies developing according to the text?A.Robots will become smarter and smarter.B.Uber’s labor cost will be lower and lower.C.More and more truck drivers will be needed.D.Taxi drivers can enjoy more health insurance.3.Which of the following does the writer agree on?A.Welcoming foreign trade.B.Offering more part-time jobs.ing fewer robots to stop job loss.D.Developing more new technologies.4.What’s the writer’s main purpose in writing the text?A.To show technology advances in our daily life.B.To prove technologies cause low incomes.C.To introduce what the Gig Economy is.D.To warn the Gig Economy is coming.语篇解读:本文为一篇议论文。
