If businesses are to get workers back into the office, finding ways to keep social distancing(社会隔离)will be important. An Israeli company thinks it can help, using smart sensors installed on workplace ceilings.

PointGrab developed its technology before COVID-19 to help workspace managers optimize(优化)how employees use office space. About the size of a smoke alarm, the sensors can record the exact number and location of people in buildings including offices, hotels and restaurants. One of the company's first clients was Deloitte, which installed the system at its London office last year. PointGrab s sensors were connected to screens in the building to show the availability(利用率)of desks and shared areas in real time. PointGrab CEO Doron Shachar says it was one of a series of innovations that helped Deloitte fit 30% more people into 3% less space.

Now to prevent the coronavirus spreading face to face, PointGrab has adapted the technology to some degree so the sensors can also monitor social distancing by keeping track of how far apart people are, and whether they're traveling in one direction around a building. Workspace managers can set up alarm for when two people are closer than two meters for more than 30 seconds, for example. The sensors have been included in the “six feet office” concept created by a company Cushman & Wakefield to encourage employees to practice social distancing. They are currently being used in this way at a university in the Netherlands, and at an innovation centre in Belgium. While the social distancing innovation is new, PointGrab has installed more than 10, 000 sensors for workspace optimization, including in the offices of Coca-Cola, Facebook and Dell.

Workers might not like the idea of being monitored, but PointGrab says no images or identifying features are recorded. Instead, each employee is represented as a dot on a screen. “The sensor does not violate people’s privacy,” Shachar says. This is extremely important in the workspace.

1. What were the sensors used to do before COVID-19?
A.To identify employees.B.To record locations.
C.To keep track of employees.D.To make better use of office space.
2. What does the underlined word “adapted” probably mean in Paragraph 3?
A.Introduced.B.Adjusted.
C.Formed.D.Boomed.
3. What can be inferred from the last paragraph?
A.Smart sensors give away people’s privacy.
B.PointGrab is in good conditions.
C.Workers are in favor of the company management.
D.Worker appearance will not show clearly on the screen.
4. Which of the following is the best title for the text?
A.How we can get workers back into their office
B.How we can improve the employees’ efficiency
C.Smart sensors make office social distancing easier
D.Smart sensors are a key technological innovation

【推荐1】Disability aids are vital to those who suffer problems with executing work with two hands. These are people who have been disabled due to some major sickness or some other problems. In order to help them carry on their work in the normal way, disability aids are manufactured. This helps them make their life a lot easier than what it would have been without these aids. The kind of disability aids that an individual might require depends on the person only. It is the problem that a person faces that decides the aids that he/she will use for carrying out their respective jobs. The following is the list of a few disability aids that come of significant use.

The first and foremost aid is the stocking aid, aiding the individuals suffering from the problem of bending down to reach the foot and wear their own socks. These stocking aids have a gutter that is made up of plastic material. These gutters are shaped in a certain way along with the attachment of cotton tapes in it. The sock is then put over the gutter. The foot is placed inside the gutter. The cotton tapes help in pulling the socks up the leg and subsequently the sock. In this manner, the sock is worn by a person who has problems wearing it by bending one’s back and reaching the foot.

There are openers that help the people who have problems with their hands or wrists to open bottles of ketchup, jam and other such bottles and jars that necessitates the use of hands and fingers.

The third type of disability aids that comes to our minds are lifts. Now what are lifts? Lifts are certain machines that help in lifting people from specific areas, such as a bathtub or a set of stairs. These lifts are of varied types and come for numerous applications. It is for the individual to decide the type that he/she requires to use.

For people, who have problems in balancing their upper bodies in a stable manner, there is something known as grab rails. These grab rails are installed for those who have mobility problems in their upper bodies. These rails come in varieties of shapes, sizes and angles. These grab rails are available to home users as well, in their different variations. One can purchase and fix one to their homes according to one’s specificities. These grab rails require the act of screwing and drilling in order to fix them to their appropriate place. The prices of these rails also vary according to the variation of their shapes and sizes.

A portable book holder is a much sought-after disability aid. It can be used by anybody for that matter, not just the disabled. These portable book holders are light-weight and can be easily moved about. These holders relieve the strains on one’s hands, necks and shoulders that might occur due to the handling of a book. The holders are provided with extended legs that help in placing the reading material at suitable distance.

Thus with the help of these disability aids, the old and disabled people can make their lives much more convenient and comfortable that would otherwise have been a cumbersome and complex one.

文章大意:这是一篇说明文。文章主要介绍荷兰Eindhoven University of Technology的学生团队研发了一款能吸收碳的电动汽车。

【推荐2】The sporty all-electric car from the Netherlands resembles a BMW coupe, but is unique: It captures more carbon than it emits.

“Our end goal is to create a more sustainable future,” said Jens Lahaije, finance manager for TU/ecomotive, the Eindhoven University of Technology student team that created the car.

Called ZEM, for zero emission mobility, the two-seater houses a Cleantron lithium-ion (锂离子) battery pack, and most of its parts are 3D-printed from recycled plastics, Lahaije said. The target is to minimize carbon dioxide emitted during the car’s full lifespan, from manufacturing to recycling, he added.

Battery electric vehicles emit virtually no CO2 during operation compared with fuel vehicles, but battery cell production can create so much pollution that it can take EVs (Electric Vehicles) tens of thousands of miles to achieve “carbon parity (相等)” with comparable fossil-fueled models.

“Direct air capture is a fairly new method of cleaning the air by capturing CO2 into a filter (过滤器). We have made use of this innovative technology and implemented this in our car. The idea is very simple: while we’re driving, air will move through our self-designed filters and the CO2 will be captured and stored.”

ZEM uses two filters that can capture up to 2 kilograms of CO2 over 20,000 miles of driving, the Eindhoven team estimated. They imagine a future when filters can be emptied at charging stations.

The students are showing their vehicle on a US promotional tour to universities and companies from the East Coast to Silicon Valley.

1. What does the article tell us about ZEM?
A.The four-seater is equipped with a lithium-ion battery pack.
B.All of its parts are modern plastics.
C.The process of manufacturing the car creates little pollution.
D.The CO2 can be caught and stored while we’re driving.
2. What does the underlined word “emit” mean in paragraph 4?
A.take inB.give offC.put asideD.clear off
3. What is the main idea of paragraph 5?
A.What challenges the students met.
B.How the students got this idea.
C.How this innovative technology works.
D.How this technology can be improved.
4. What’s the best title for this passage?
A.A Newly-invented Sporty Car Has Gained Great Popularity.
B.All-electric Car or Fuel-engine Car?
C.Dutch Students Devise Carbon-eating Electric Vehicle.
D.The Advantages of the Sporty All-electric Car.

【推荐3】Google’s AlphaGo defeated the South Korean Go grandmaster Lee Sedol four games to one Artificial intelligence had suddenly reached a new and unexpected height.

But AlphaGo is no longer the best Go “player” in the world Google’s artificial intelligence group, DeepMind. has created the next generation of its Go-playing program, called AlphaGo Zero The new A1 program is unique in the way it learned to play Go Instead of learning from human matches, as its predecessor (前任) did, AlphaGo Zero mastered Go in just two days without any human knowledge of the game and defeated AlphaGo by day three, reported The Guardian It then went on to defeat AlphaGo 100 games to zero.

To learn how to play Go, AlphaGo Zero played millions of matches against itself using only the basic rules of the game to rapidly create its own knowledge of it tike the previous version, it used “reinforcement (增强) learning to become its own teacher, ”ccording to DeepMind’s website.

“It’s more powerful than previous approaches. ’’ David Silver,   AlphaGo’s lead researcher, told The Guardian, “because by not using human data, or human expertise in any fashion, we’ve removed the constraints (约束) of human knowledge and it is able to create knowledge itself . ”

AlphaGo Zero’s approach to selt-learning is a significant advancement in AI could be applied to help solve some of the world s biggest problems, according a recent research report published in the journal Nature. For example, DeepMind co-founder DemisHassabis argues that AlphaGo Zero could probably find cures for a number of serious diseases within weeks, according to The Telegraph Indeed, the AI is now being used to study protein folding, which is connected to diseases such as Parkinson’s and Alzheimer’s.

So now that AI has surpassed human beings in some ways, perhaps the question is not about what AI can learn from humans, but what humans can learn from AI We can only wait and see.

1. What can we learn from the first two paragraphs?
A.AlphaGo defeated Lee Sedol five games to zero
B.AlphaGo Zero defeated AlphaGo within one day
C.AlphaGo Zero is the first program to defeat a human at Go
D.AlphaGo Zero has become the new best Go player
2. How is AlphaGo Zero different from previous Go-playing programs?
A.It can collect human knowledge automatically
B.It can create knowledge with human data
C.It can become its own teacher in learning Go skills
D.It can play many matches without a break
3. What’s the possible application of AI in the future according to the aiticle?
A.Treating diseases.B.Making new Go rules.
C.Solving math problems.D.Creating new proteins.
4. Which of the following can replace the underlined word “surpassed” ?
