One argument for why robots will never fully measure up to people is because they lack human-like social skills. But researchers are experimenting with new methods to give robots social skills to better interact with humans.
The experiment was carried out by researchers from the Massachusetts Institute of Technology(MIT). The team developed a machine learning system for self-driving vehicles that is designed to learn the social characteristics of other drivers. The researchers studied driving situations to learn how other drivers on the road were likely to behave. Since not all human drivers act the same way, the data was meant to teach the driverless car to avoid dangerous situations.
The researchers say the technology uses tools borrowed from the field of social psychology. In this experiment, scientists created a system that attempted to decide whether a person's driving style is more selfish or selfless. In road tests, self-driving vehicles equipped with the system improved their ability to predict what other drivers would do by up to 25 percent.
In one test, the self-driving car was observed making a left-hand turn. The study found the system could cause the vehicle to wait before making the turn if it predicted the oncoming drivers acted selfishly and might be unsafe. But when oncoming vehicles were judged to be selfless, the self-driving car could make the turn without delay because it saw less risk of unsafe behavior.
The MIT team plans to expand its research model to include other things that a self-driving vehicle might need to deal with. These include predictions about people walking around traffic, as well as bicycles and other things found in driving environments. The researchers say they believe the technology could also be used in vehicles with human drivers. It could act as a warning system against other drivers judged to be behaving aggressively.
1.What is the purpose of the new research?
A.To reduce human drivers' mistakes.
B.To develop a machine learning system.
C.To give robots human-like social skills.
D.To prove robots can never replace humans.
2.What caused the self-driving car to wait or turn quickly?
A.The colors of the traffic lights.
B.The orders from police officer.
C.The directions from human drivers.
D.The oncoming driver's driving style.
3.What can we learn from the last paragraph?
A.More traffic participants will be involved in the research.
B.Other colleges will be invited to join in the project.
C.New rules will be developed for road users.
D.Human drivers will give way to robots.
4.In which section of a newspaper may this text appear?

If humans ever settle on Mars, they will need water. There is just one problem---there seems to be only huge sheets of ice. Luckily, we know how to drill(钻孔） ice for water. Such methods are already used in Antarctica, and researchers now think they could get them to work on the Red Planet, too. The atmosphere of Mars is too dry to make extracting water vapour from it possible. So ice seems the best bet. But the obvious ice sheets are in the unlivable polar ice caps and would be difficult to reach for drilling.
However, in 2018, at the edge of the cliffs, NASA's Mars Reconnaissance Orbiter spotted relatively accessible water ice that is probably at least 130metres thick and covered in just a few metres of rock and dust. These may be the best place to get the water needed for future exploration of the planet.
The drilling techniques needed have already been developed for cold areas on Earth where we need to melt buried ice for water. In the early 1960s the US Army used a type of subsurface reservoir(水库)called Rod Well, in army camps in Greenland. The method works by drilling through the ground into the ice, melting the ice to create a pool, and then pumping water up. By supplying heat continuously, they create a reservoir and a steady water supply. It has been used in remote areas such as the Amundsen-Scott South Pole Station Stephen Hoffman at the Aerospace Corporation in Texas and his colleagues simulated(模拟)how a Rod Well would do on Mars. They found that with the power of 9 kilowatts (千瓦)to melt ice, it could in theory produce about 380 litres of water each day and maintain a reservoir of constant size at the bottom of a borehole(钻孔). That is close to the average daily water use each person in the US, but about 10 times what each astronaut on the International Space Station uses daily.
1.Which of the following can replace the underlined word "extracting" in the first paragraph ?
A.obtaining B.protecting
C.Preventing D.choosing
2.Why does the author mention the Rod Well in Paragraph 3?
A.To explain how water ice is drilled on Mars.
B.To tell about the history of water ice drilling techniques.
C.To prove the importance of water ice drilling techniques
D.To show techniques for drilling water wells in Martian ice exist.
3.On average, how much water does an astronaut on the International Space Station use daily?
A.10 litres B.38 litres
C.160 litres D.380 litres
4.What would be the best title for the text?
A.Preparing to settle on the Red Planet one day.
B.Finding water on the Red Planet for survival.
C.Using some ways to create a livable environment on Mars.
D.Drilling water wells in Martian ice to survive on Mars.

No one should be forced to wear a uniform under any circumstance. Uniforms are controlling the human spirit and totally unnecessary in a democratic(民主的) society. Uniforms tell the world that the person who wears one has no value as an individual but only lives to function as a part of the whole. The individual in a uniform loses all self-worth.
There are those who say that wearing a uniform gives a person a sense of identification with a larger, more important concept. What could be more important than the individual himself? If an organization is so weak that it must rely on cloth and buttons to inspire its members, that organization has no right to continue its existence.
Others say that the practice of making persons wear uniforms, say in school, gets rid of all envy and competition in a matter of dress, such that a poor person who cannot afford good-quality clothing is not to be looked down upon by a wealthy person who wears expensive clothing. Those persons ignore the concepts as freedom of choice, motivation, and individuality. If all persons were to wear the same clothing, why would anyone struggle to be better? It is only a short step from forcing everyone to drive the same car, have the same type of food. When this happens, all motivation to improve one’s life is removed. Why would parents bother to work hard so that their children could have a better life than they had when they know that their children are going to be forced to have exactly the same life as they had?
Uniforms also hurt the economy(经济). Right now, billions of dollars are spent on the fashion industry yearly. Thousands of people are employed in designing, creating, and marketing different types of clothing. If everyone were forced to wear uniforms, artistic personnel would be unnecessary. Salesmen would be extra as well. Why bother to sell the only items that are available? The wearing of uniforms would destroy the fashion industry which in turn would have a wave effect on such industries as advertising and sales promotion. Without advertising, newspapers, magazines, and television would not be able to remain in business. Our entire information and entertainment industries would collapse.
1.Why does the author discuss forcing everyone to buy the same car or eat the same food?
A. To show that freedom of choice is absolute in modern society.
B. To suggest what would happen if uniforms became compulsory.
C. To predict the way the society will be in the next few generations.
D. To show that the government has too much control over people’s lives.
2.The last word of the passage “collapse” probably means ________.
A. fail B. rise C. disappear D. struggle
3.The author’s primary purpose in writing this passage was to ________.
A. show that uniforms are not possible in a democratic society
B. advise the government to change the rules of wearing uniforms
C. advocate stronger governmental controls on the wearing of uniforms
D. convince the reader that uniforms have more disadvantages than advantages

The idea of being able to walk on water has long interested humans greatly. Sadly, biological facts prevent us ever accomplishing such a thing without artificial aid---we simply weigh too much, and all our mass pushes down through our relatively small feet, resulting in a lot of pressure that makes us sink.
However, several types of animals can walk on water. One of the most interesting is the common basilisk Basilicus basilicus, a lizard (蜥蜴)native to Central and South America. It can run across water for a distance of several meters, avoiding getting wet by rapidly hitting the water’s surface with its feet. The lizard will take as many as 20 steps per second to keep moving forward. For humans to do this, we，d need huge feet that we could bring up to our ears in order to create adequate w hitting. ’’
But fortunately there is an alternative : cornflour. By adding enough of this common thickening agent to water (and it does take a lot), you can create a “non-Newtonian” liquid that doesn’t behave like normal water. Now, if the surface of the water is hit hard enough, particles(粒子）in the water group together for a moment to make the surface hard. Move quickly enough and put enough force into each step, and you really can walk across the surface of an adequately thick Liquid of cornflour.
Fun though all this may sound, it’s still rather messy and better read about in theory than carried out in practice. If you must do it, then keep the water wings handy in case you start to sink--and take a shower afterward!
1.Walking on water hasn’t become a reality mainly because humans______.
A. are not interested in it
B. have biological limitations
C. have not invented proper tools
D. are afraid to make an attempt
2.What do we know about Basilicus basilicus from the passage?
A. It is light enough to walk on water.
B. Its huge feet enable it to stay above water.
C. It can run across water at a certain speed.
D. Its unique skin keeps it from getting wet in water.
3.What is the function of the cornflour according to the passage?
A. To create a thick liquid.
B. To turn the water into solid.
C. To help the liquid behave normally.
D. To enable the water to move rapidly.
4.What is the author’s attitude toward the idea of humans’ walking on water?
A. It is risky but beneficial.
B. It is interesting and worth trying.
C. It is crazy and cannot become a reality.
D. It is impractical though theoretically possible.
