Technology offers conveniences such as opening the garage door from your car or changing the television station without touching the TV.

Now one American company is offering its employees a new convenience: a microchip implanted (把……植入) in their hands. Employees who have these chips can do all kinds of things just by waving their hands. Three Square Market is offering to implant microchips in all of their employees for free. Each chip costs $ 300 and Three Square Market will pay for the chips. Employees can volunteer to have the chips implanted in their hands. 50 out of the 80 employees have chosen to do so. Todd Westby is Chief Executive Officer of Three Square Market. Westby and his wife, and their children are also getting chips implanted in their hands.

The chip is about the size of a grain of rice. Implanting the chip only takes about a second and is said to hurt only very briefly. The chips go under the skin between the thumb and forefinger. With a chip in the hand, a person can enter the office building, buy food, log in to computers and more, simply by waving that hand near a scanner. The chips will be also used to identify employees. Employees who want convenience, but do not want to have a microchip implanted under their skin, can wear a wristband(腕带) or a ring with a chip instead. They can perform the same tasks with a wave of their hands as if they had an implanted chip.

Three Square Market is the first company in the United States to offer to implant chips in its employees. Epicenter, a Digital House of Innovation in Sweden, has implanted chips in its employees for a while.

Three Square Market says the chips cannot track the employees. The company says scanners can read the chips only when they are within a few inches of them. "The chips protect against identity theft, similar to credit cards." The U. S. Food and Drug Administration agreed the chips back in 2004, so they should be safe for humans, according to the company.

In the future, people with the chips may be able to do more with them, even outside the office. Westby says, "Eventually, this technology will become standardized, allowing you to use this as your passport, for public transit, all purchasing opportunities, etc."

1. What is the third paragraph mainly about?
A.The potential risks of implanting the chips.B.The replacement of the chips.
C.The places to implant the chips.D.The advantages of the chips.
2. What does the underlined word "them" in Paragraph 5 refer to?
A.The hands.B.The scanners.
C.The employees.D.The credit cards.
3. What can we infer from the passage?
A.The chips have magic powers.
B.The price of the chips is reasonable.
C.The chips are very popular among the employees.
D.Most people suspect the application of the chips.
4. Which of the following best describes Todd Westby's attitude towards the chips?

文章大意:本文是一篇说明文。文章主要讲述了人工智能欺骗探测器以及它是如何工作的,同时人工智能技术可以作为人类的辅助手段。

【推荐1】Can artificial intelligence uncover a liar? It sounds like science fiction, but such an AI system is possible. Rada Mihalcea, a professor of computer science and engineering at the University of Michigan, has worked on deceit (欺骗) detection for about a decade.

The first thing that researchers working on artificial intelligence and machine learning need is data. In the case of the work that Mlhalcea did, they began with videos from actual court cases. For example, a defendant speaking in a trial in which he is found to have committed a crime could provide an example of deceit; they also employed words from witnesses as either example of truthful or deceitful statements. Altogether, they analyzed 121 videos — about half represented dishonest statements, and half truthful. It was this data that they used to build machine learning deceit detectors that ultimately had between a 60 to 75 percent accuracy rate.

One thing the system noticed is the use of pronouns—people who are lying would tend to less often use the word “I” or “we”, Mihalcea explains. “Instead, people who are lying would more often use ‘you,’ ‘yours’.” Besides, someone telling a lie would use “stronger words” such as “absolutely,” and “very,” that reflect certainty, while interestingly, people telling the truth were more likely to use words such as “maybe” or “probably.” As for gestures, she points out that someone being deceitful would be more likely to look directly into the eyes of the person questioning them. They also tended to use both hands when gesturing.

However, Mlhalcea’s work is “far from perfection,” she admits. “As a researcher, we are content that we were able to get to 75 percent accuracy. But looked at another way, that’s an error rate of one in four. ” Ultimately, she sees technology like this as being assistive for people — it could indicate that it noticed something “unusual” in a speaker’s statement, and then perhaps have a person “investigate more. ”

1. How did researchers create the deceit detection using artificial intelligence?
A.They interviewed criminals in court cases.
B.They involved AI system in a real-life trial.
C.They employed witnesses to identify dishonest criminals.
D.They fed the system with both truthful and deceitful statements.
2. According to the passage, what is a liar likely to do?
A.Gesture with one hand.B.Question others directly.
C.Use pronouns repeatedly.D.Speak with strong certainty.
3. What does Mlhalcea think of her work?
A.It completely lives up to her expectation.
B.It can be used as an aid for human beings.
C.It can replace human beings to uncover a lie.
D.It successfully lowers the error rate of detection.
4. Which is the most suitable title for the text?
A.The use of pronouns and gestures in lie
B.Rada Mihalcea’s research on lie detection
C.The limitations of current lie detection technology
D.Accuracy rate of machine learning deceit detectors

【推荐2】Homemade Soup May Fight Malaria

A new study suggests that some homemade soups — made of chicken, beef or vegetables — might help fight malaria.

Jake Baum of the Imperial College London led the research. He asked children at a London school to bring in homemade clear soups that their families would make to treat a fever. The children were from many different cultural backgrounds.

The soups were then exposed to the parasite (寄生虫) that creates 99.7 percent of malaria cases in Africa, the World Health Organization, WHO, explained.

Of the 56 soups tested, five were more than 50 percent effective in containing the growth of the parasite. Two were as effective as one drug now used to treat malaria. And four soups were more than 50 percent effective at preventing parasites from aging to the point that they could infect mosquitoes that spread the disease. Baum also noted that it was unclear which foods made the soups effective against malaria.

The soups came from families from different ethnic histories, including Europe, North Africa and the Middle East. They had several main ingredients, including chicken, beef and green vegetables. Baum said the vegetarian soups showed similar results to the soups with meat.

Baum said his aim was in part to show children that scientific research can turn a herbal cure into a man-made medicine. He noted the research of Dr. Tu Youyou of China. In the 1970s, she found that the herb quinhao was an effective antimalarial treatment. The herb has been used in Eastern medicine for two thousand years. Tu’s research led to the man-made drug artemisinin (青蒿素), a drug now widely used to treat malaria. She won the Nobel Prize in 2015.

More and more people are becoming resistant to the drugs that treat the disease, which kills about 400,000 people a year. That means scientists will have to “look beyond chemistry” and find new drugs, Baum adds.

1. What do we know about the research led by Jake Baum?
A.50% of the soups tested proved to be effective in killing the parasite.
B.Half of the soups tested show oppositive effect in stopping mosquitoes from spreading the disease.
C.A few of the soups tested can be seen as effective against malaria, yet what in soup that works is not known.
D.The vegetarian soups and the soups with meat work similarly but in different aspects.
2. The soups came from the following ethnic histories EXCEPT ________.
A.East Asia.B.the Middle East.
C.North Africa.D.Europe.
3. Why does Baum take Dr. Tu Youyou as an example?
A.To show her great achievement in treating malaria through hard work.
B.To note artemisinin she found in the herb quinhao, an herb used in Chinese medicine for 2000 years.
C.To show kids science research can develop an herbal cure into a man-made medicine.
D.To stress the .most important use of quinhao in treating malaria in Eastern medicine.
4. How serious is malaria in the world?
A.It is out of control in Africa.
B.It kill less than half a million people every year.
C.It is becoming resistant to most of the drugs used now.
D.It caused 99.7% the deaths in the whole world.
5. What is scientists’ task next?
A.To collect more soups to get the most effective ones.
B.To research into the ingredients of the soups gathered.
C.To find out the most effective elements in the soups.
D.To expand their studies and get new antimalarial medicines.

【推荐3】Scientists are using robots to study the health of waters in and around Venice, Italy. The robots are designed to act like fish, other underwater creatures and plants. The scientists are working with several universities and research centers as part of a group called subCULTron. The European Union gives money to the project as part of its Horizon 2020 program whose aim is to take great ideas from the lab to the market and support science and innovation (创新) in Europe. The scientists want to use the artificial intelligence of the robots to help humans understand what is happening under the water of the Venice lagoon (潟湖).

SubCULTron, a collective artificial intelligence project, plans to create the biggest shoal (鱼群) of robot fish in the world. The project’s aim is to improve knowledge of the seabed and try to turn human abilities into hi-tech items.

Alexandre Campo, a computer scientist, says the scientists have looked at the way animals learn to work in groups to understand how robots can learn to work together. The subCULTron project wants its robots to learn to work together so they can watch out for changes and new problems in the water.

One problem the researchers had in the beginning was how the robots would communicate with each other. Wi-Fi and GPS equipment don’t work underwater. Instead,the robots can use sonar (声呐) and an electric field.

Another problem was charging batteries. The robots come up to the water’s surface and stay near a boat or a power station to charge without any electrical cables. Besides, how to be water- proof, especially for some key pads of the robots, was really tough. Fortunately, a special mixture has been created to be pinned on the robot, which successfully stands the test of water.

The health state of the lagoon is pretty good. There are no industrial polluters, and the city now has a modem sewer (污水管) system. It’s not like before when all the waste flushed directly into the water. The robots in Venice will continue their work until 2019. The subCULTron project hopes they develop into “an artificial society underneath the water surface” that serves “a human society above the water”.

1. What can we learn about the project in Paragraph 1?
A.Its researchers are all from universities.
B.The European Union has financially supported it.
C.It uses robots to clean the waters in and around Venice.
D.It is aimed to support science and innovation worldwide.
2. What can we infer according to Alexandre Campo?
A.Scientists have got an idea for robots from the animals.
B.The robots are working separately to perform their tasks.
C.SubCULTron is to turn human abilities into hi-tech items.
D.The health state of the lagoon has greatly improved recently.
3. The underlined word “they” in the last paragraph probably refers to “      ”.
A.scientistsB.animals
C.robotsD.humans
4. What does the author mainly want to tell us in the passage?
A.Robots are coining into our cities soon.
B.Animals can tell us how to clean the water.
C.Waters in Venice have been greatly cleaned.
D.Robot fish watch out for the waters in Venice.
