worker.C.Employees at Coffee Beans have few management chances.D.Applicants to Wowee Magazine are supposed to be sociable and enthusiastic.BFrom self-driving cars to carebots(care+robots)for elderly people,rapid development in technology has long represented a possible threat(威胁)to many jobs normally performed by people.But experts now believe that almost50 percent of occupations existing today will be completely unnecessary by2035as artificial intelligence(AI)continues to change businesses.“The next fifteen years will see a revolution in how we work,and a revolution will necessarily take place in how we plan and think about workplaces,” said Peter Andrew,Director of Workplace Strategy for CBREAsia-Pacific.A growing number of jobs in the future will require creative intelligence,social skills and the ability to use artificial intelligence.The report is based on interviews with200experts,business leaders and young people from Asia-Pacific,Europe and North America.It shows that in the US technology already destroys more jobs than it creates.But the report states,“Losing occupations does not necessarily mean losing jobs—just changing what people do.” Growth in new jobs could occur as much,according to the research.“The growth of companies that have the speed and technologicalknow-how will directly challenge big companies,” it states.A2019report by Pew Research Centre found52per cent of experts in artificial intelligence and robotics were optimistic about the future and believed there would still be enough jobs in the next few years.The optimists pictured“a future in which robots do not take the place of more jobs than they create,” according to Aaron Smith,the reports co-author.“Technology will continue to affect jobs,but more jobs seem likely to be created.Although there have always been unemployed people,when we reacheda few billion people there were billions of jobs.There is no shortage of thingsthat need to be done and that will not change,” Microsoft's Jonathan Grudintold researchers.4.What is the first paragraph mainly about?A.The result of job reduction.B.The fast development of AI.C.The future life of elderly people.D.The influence of technology on jobs.5.What will people most probably do in the future?A.Take the place of AI.B.Work in a traditional way.C.Take up jobs requiring creativity.D.Enjoy life without working anymore.6.What can be known from Grudin's words in the last paragraph?A.Unemployment will stay high.B.More jobs tend to appear in the future.C.Job competition is likely to grow fiercer.D.Technology will have less control over jobs.7.What is the best title for the text?A.Are people losing their jobs?B.The requirements for future jobsC.The challenging life in the futureD.Does technology simplify everything?CMany automobile makers present their newest designs at car shows around the world.Many designers seek to create the car of the future.One device thatis popular among car manufacturers(生产商)is an autopilot.An autopilot permits a car to drive itself without human control.A recent car show in Geneva,Switzerland also presented other possible designs,including cars manufactured on3D printers.Rinspeed is a Swiss design company.It showed a vehicle based on the US electric car Tesla Model S,but the Rinspeed car includes a large television and an espresso coffee maker.Frank Rinderknecht is the CEO of Rinspeed.He says he does not want to just sit and watch the steering wheel(方向盘)turn as he rides in a car with an autopilot.“I want to ride;I want to sleep,relax,watch movies,news,and anything else.So that's the vision which we have.One day on the boring motorway traffic,you just do anything that makes your life better,” said Rinderknecht.One of the most interesting ideas presented at the show is a car built on a 3D printer.The German engineering firm EDAG designed the car.The body of the vehicle called“Genesis” is printed in one piece from a material called thermoplastic(热塑性塑料).Christoph Horvath is a spokesman for EDAG.“To create a car without the use of any tool,this would be a real revolution for the industry,” said Horvath.EDAG said it based its design on a turtle shell.The company said the design provided the right amount of strength and firmness.Other automakers did not look so far into the future.Czech automaker Skoda presented its“Vision C” model vehicle.The car has an environmentally friendly natural gas engine.Jo Davidson is a company spokeswoman.She said the car released very low levels of the pollutant gas CO2.Ms Davidson said the“Vision C” planned to be launched in two years.8.Why is an autopilot popular among car manufacturers?A.Because it can get a car to drive itself.B.Because it can make a car more modern.C.Because it may let a car fly in the sky freely.D.Because it has a car moving in a particular direction.9.What is the common feature of the cars?A.They are all made from thermoplastic.B.They all belong to the cars of the future.C.All the designs are based on a turtle shell.D.They have environmentally friendly natural gas engines.10.Where can we most probably read this text?A.In an economic report.B.In a short story.C.In a travel magazine.D.In a technology report.11.What do we know about the vehicle called“Genesis”?A.It is designed by the American engineering firm.B.The body of the vehicle is built on a3D printer.C.Frank Rinderknecht is the designer of the car.D.The car is mainly made from the turtle shell.DWalmart will soon use360robot cleaners across a few hundred of its ing maps input by human employees,the AI-powered cleaners will travel in the store with no difficulty,sweeping the floor—just as human employees used to do.Perhaps the most striking thing about these robot workers is how not-striking they are.Sci-fi movies suggest a future full of human-like robots who appear with their horrible qualities.Now the future is coming into view,and it looks like a giant lie.It's easy to imagine walking past an Auto-C on a shopping trip without even noticing its presence.AI has already started to become a part of our everyday life.In New Jersey this week,dozens of workers were hospitalized after a robot at an Amazon fulfillment centre accidentally broke a can and enveloped workers in an eye-and-lung-damaging gas.Days earlier in California,an auto-piloted Tesla drove a drunk,sleeping driver down a highway,which no doubt did some potential risk to the other drivers on the road.Highway patrol officers figured out on the spot how to stop the AI car.Of course,industrial accidents and drunk drivers existed as well before AI. Tools with the power to release the burden of physical labor—horses,steam machines,self-driving cars—also come with the power to injure people.And thepresence of AI-powered machines that just steps away from us is,for now,still a rare thing for most people.But the nature of robots'coming into our daily life will make it harder to recognize—or object to—the bigger changes they bring later.Walmart insists that the robot cleaners give employees more time for customer service and other tasks.Critics point out that they could just as easily become an excuse to reduce staff and wages.12.What is the difference between sci-fi movies and the reality?A.Now the human-like robots are hard to recognize.B.Now people don't go to see the sci-fi movies.C.Now the human-like robots can tell lies.D.Now it is easy to ignore the robots.13.Why were some workers in hospital in New Jersey?A.Because they damaged the robot first.B.Because the robot caused an accident on purpose.C.Because the robot made a mistake by chance.D.Because the robot driving them on the highway had an accident.14.What is the attitude of the author to AI?A.Supportive.B.Objective.C.Doubtful.D.Indifferent.15.What is the main idea of the passage?A.Artificial intelligence is bringing great effects to our daily life.B.Walmart will soon use360robot cleaners across its stores.C.We should say no to artificial intelligence.D.Artificial intelligence is dangerous to our life.第二节(共5小题;每小题2.5分,满分12.5分)阅读下面短文,从短文后的选项中选出可以填入空白处的最佳选项。

You will probably love it. I know I did. You should join some sports or activities that will make your high school experience more enjoyable. Good luck!Sharon, Aged 22The most important thing to keep in mind whengoing into high school is to be yourself. Besides, I don't knowwhat your middle school was like, but high school teachers will not care about things such as how much homework you already have in one night. It's best to learn to deal with things and manage your time wisely so you can achieve everything you need to do.Eddie, Aged 20When I started high school, I was really nervous too, especially since I had been homeschooled （家中教学） all through middle school and didn't really know anyone. I suppose the best advice would be to just relax. The first couple of days can be a little bit hard, but things will become easier before you know it.David, Aged 19I'm not going to lie. The first day is kind of frightening. But you'll get used to it. Don't be afraid of anyone; upperclassmen （高年级学生） will pick on you more if you let them know you're afraid. Just take it easy. Making some friends and staying with them will greatly help you get used to high school quickly. After the first week it's really not bad at all.

I looked at her for a few moments, wondering how I got into this mess （困境）, when suddenly an idea came to me.Picking up two baskets from the living room, I explained, “ When everyone is born, he or she has a little basket, This little one here is yours. The big one is mine. As you grow ，so does the basket. You can see your little basket is inside mine because when you were born, there were too many things you couldn't do for yourself. I did everything you couldn't do on your own.”She nodded.“ Well, as you grew older and began to do some things on your own, I began placing a few more things in your basket. When you learned to tie your shoes, that went in your basket. ”She said softly, “I can tie my own shoes. ”“ Right. As you grow older, there will be more and more things you must do on your own. ” As I spoke, I gradually took her basket out of mine and handed it to her. “ You will finally carry your own basket with things only you can do. ”She looked up at me and said, “ I understand.
