When it comes to work, workers, and jobs, much of the concern of the modern age boils down to the fear that we're witnessing the final stage of the game, and that there will be nowhere for humans to withdraw as machines take over the last few tasks. The most recent example comes from the use of artificial intelligence (AI). Is there no area of human experience that can't be replaced by AI? And if not, what is left for humans to do except the tasks involved in taking care of the machines?

At the heart of this concern is our desire for good jobs — jobs that make the most of workers' natural abilities and where the work provides the worker with motivation and work-life balance. More importantly, good jobs support workers in learning by doing—and, in so doing, deliver benefits on three levels: to the worker, who gains in personal development and job satisfaction; to the organization, which reforms as staff find new problems to solve and opportunities to pursue; and to the community as a whole, which harvests the economic benefits of hosting positive organizations and workers. This is what makes good jobs productive for the organization, as well as engaging and fulfilling for the worker.

Does the ongoing advance of AI threaten to get rid of all the learning, creativity, and meaning that make a job a good job? Certainly, some have blamed technology for just such an outcome. Headlines today often express concern over technological innovation(革新) resulting in bad jobs for humans, or even the complete disappearance of certain professions. Some fear that further technology advancement in the workplace will result in jobs where employees are being asked to work in split times or for longer periods over more days.

The problem here isn't the technology; rather, it's the way the technology is used — and, more than that, the way people think about using it.

1. What is the passage mainly about?
A.The human fears in the age of AI.
B.Human experiences were replaced by AI.
C.How to take care of the AI machines.
D.The relations among work, workers, and jobs.
2. What jobs are supposed to be good according to the passage?
A.The ones that provide basic benefits.
B.The ones that require no economic return.
C.Those that don't bring new problems to workers.
D.Those that offer chances to progress professionally.
3. How do news media respond to the development of AI?
A.Supportive.B.Optimistic.C.Negative.D.Ambiguous.
4. What will the author probably talk about next?
A.The proper attitude towards AI.B.The future jobs humans will do.

文章大意:这是一篇说明文。文章主要说明了一个韩国研究小组报告说,他们已经创造出LK-99,一种在室温和常压水平下工作的超导体。文章介绍了这种超导体的特性以及超导体成为世界科学的焦点的原因。

【推荐1】A surprising discovery was reported by a team of South Korean researchers in late July. They said that they had created LK-99, a superconductor (超导体) that works at room temperatures and normal pressure levels.

When electricity travels through wires (电线), it loses some energy and heats up along the way because of resistance (电阻). Superconductors can let electricity flow through without any resistance. However, according to Science Daily, they usually only work at very low temperatures, around -200℃. It makes them difficult to produce and use.

After the team’s report, LK-99 became the center of discussion. Scientists around the world began to copy the steps. However, as of mid-August, researchers had published several new reports showing that LK-99 is not a superconductor at room temperature. It was rather a magnetic material that has some characteristics of superconductors, said The New York Times.

Early in March, US scientists also said they had created such material, but the research is still waiting to be proved. Why have superconductors been a key focus of world science?

It could make the energy systems more efficient. Currently, around 8 to 15 percent of electricity is lost between the generator (发电站) and the user, according to China’s CHINT Group, a leading new energy company with a global presence. Superconductors ensure that the loss will be no more. Each wire can carry much more electricity. ”The electricity prices for everyone may be reduced to one-tenth of the current prices, Xu Qingjin at the Chinese Academy of Sciences told China Daily.

With superconductors, smartphones can be charged in a very short time, maybe just seconds. Electronic cars can travel longer distances, and drivers don’t need to worry about running out of electricity in the middle of their trip. Since superconductors don’t heat up, the power grid (电网) will be safer. We can have thinner phones and laptops because fans won’t be needed to cool them.

“The development of all future technology needs the support of energy,” wrote Zhou Hongyi, founder of 360 Security Group. “The problem of energy should be considered first, rather than just creating better technology.”

1. What normally makes superconductors hard to use?
A.Their working temperature.B.Their limited availability.
C.Their zero resistance.D.Their high cost.
2. What did researchers discover about LK-99 by mid-August?
A.It is a confirmed superconductor.B.It turned out to be a magnetic material.
C.It has no potential for superconductivity.D.Its superconductivity is still not certain.
3. What do paragraphs 5 and 6 mainly talk about?
A.Current electricity shortages.B.Progress in energy technology.
C.Benefits of using superconductors.D.Difficulties in developing superconductors.
4. What does Zhou think of the development of technology?
A.People should spare no effort to achieve it.B.It requires support from various aspects.
C.It will help solve energy issues eventually.D.It should come after solving energy problems.

文章大意:这是一篇说明文。文章主要介绍了使用3D打印机为老年人设计的机器人。

【推荐2】The world’s elderly population is increasing. The number of older people — those age 60 years or older — is expected to double by 2050 and is growing faster than all younger age groups across the globe. That comes with an increasing need for caregivers which can provide 24-hour care, not only at hospitals or nursing homes, but also at private homes.

Already, caregiving robots are programmed to ask questions a nurse would ask and can keep an eye on patients for falls These robotic assistants are expected to become increasingly marketable and reach 450,000 by 2045 because of the expected caregiver shortage in the USA.

“Unluckily, the hard structure of present caregiving robots prevents them from a safe human-robot interaction (互动), limiting their assistance to only social interaction and not Physical interaction,” said Ramses Martinez,an assistant professor in Purdue’s College of Engineering. “After all,would you leave babies or old people in the hands of a robot?”

Recent advances in material science have enabled the production of soft robots with deformable (可变形的) bodies or the ability to reshape when touched, but today the complex (复杂的) design prevents the use of this technology at home.

However, Martinez and other researchers have developed a new design method which shows promise in enabling the production of soft robots using a 3D printer.

The design process has three steps. First, a user makes a computer-aided design file (文件) with the shape of the robot. The user then paints the file to show which directions the different joints of the soft robot will move. It takes the computer a few seconds to change the computer-aided model into a 3-D soft machine that can be printed using any 3-D printer.

“The soft machines move like humans. Their ability to change their body structure and movement to adapt (适应) to a wide variety of environments will improve caregiving greatly.” says Martinez.

The researchers are looking for partners to test and bring their technology to market.

1. What does the underlined word “That” in Paragraph 1 refer to?
A.The younger age group.
B.The group of older people.
C.The population across the globe.
D.The growth of the elderly population.
2. What is the disadvantage of the present caregiving robots?
A.They can’t provide safe physical interaction.
B.They can’t communicate with patients.
C.They can’t watch patients for falls.
D.They can’t provide 24-hour care.
3. What do we know about Martinez’s new design method?
A.It requires a special kind of 3D printer.
B.It makes the production of soft robots simpler.
C.It has been put onto the market.
D.It is hard for users to master.
4. What is the text mainly about?
A.The robot industry in the future.
B.Effects of population ageing.
C.Robots for the elderly created with 3D printers.
D.The development of caregiving robots.

文章大意:本文是一篇说明文。主要介绍的是“自拍”形式的变化以及由此产生的问题。

【推荐3】The “selfie” is not new; many people have always produced self-portraits (自画像). Personally I didn’t enjoy art at school, but I did remember that we were always drawing pictures of our faces. However, I think this shows just how old the self-portrait is. The only thing that has really changed is the technology which we use to create self-portraits. We have gone from pencil to the digital camera. The digital version has now become “selfie” (a word now so popular that it is named the Oxford English Dictionary Online’s “Word of the Year”).

Traditionally, the best way to take a selfie was to stand in front of a mirror. This was fine though it did look a little silly as, no matter how hard you tried, you couldn’t hide the camera. Of course, phones now have cameras on both the back and the front so you don’t need a mirror to guide you. The drawback (缺点) to this more modern method is that you can usually see the photographer’s arm in the photo.

I don’t really understand the attraction of the selfie. Taking a photo of yourself in the bathroom doesn’t provide the best scenery (especially if you forget to put the toilet seat down, gentlemen).At famous tourist attractions, it always saddens me to see people take selfies; travelling on your own is fine, but are you so mistrustful of strangers that you cannot ask a passer-by to take the photo for you?

However, there have been a lot of arguments over the selfie. Recently, one New York tourist took a selfie with a man threatening to commit suicide (自杀) on the edge of a bridge behind her; and, even more recently, Barack Obama, along with David Cameron and the Danish prime minister, Thorning Schmidt, took a “group selfie at Nelson Mandela’s funeral.

1. Why is the word “selfie” named the Oxford English Dictionary Online’s “Word of the Year”?
A.It can be written in pencil easily.
B.It is very important in the dictionary.
C.It means the development of technology.
D.It is a new word used widely and popularly.
2. Which of the following is the drawback to the traditional way of taking a selfie?
A.There are arms in the picture.
B.The camera is always in the picture.
C.The picture is often not very clear.
D.The mirror can hardly be avoided.
3. We can learn from the last paragraph that the selfie        .
A.may lead to commit suicide
B.may bring unlucky things to us
C.is not suitable at some moments
D.is popular on the ledge of a bridge
4. What’s the author’s attitude towards selfie?
A.Doubtful.
B.Negative.
C.Objective.
D.Optimistic.
