Electrical devices(仪器)could soon use power made by human energy. Scientists say they have developed an experimental device that produces electricity from the physical movement of a person walking , British scientist Max Donelan and other scientists in Canada and the United States developed the device.
The device connects to a person’s knee. As the person walks ,the device captures energy each time the person slows down. To do this ,the device helps with the slowing sown movement of the leg, the movements of the walking person push parts of a small machine that produces electricity. Using the device, an adult walking quickly could produce thirteen watts of electricity in just a minute. Donelan says walking at that speed could produce enough power to operate a laptop computer for six minutes.
There are several possible uses for the device. Developers say it could help people who work in areas without electricity to operate small computers. The device could also he used in hospitals to operate heart pacemakers(起博器), it could even be used to assist in the movement of robotic arms and legs.
The experimental version of the device weighs about one and a half kilograms, but it is too costly for most people to buy, but the researchers hope to make a lighter, less costly version, An improved version should be ready in one year.
The developers hope the device will one day help developing countries; nearly twenty five percent of people around the world live without electric power.
A similar product was invented in 2005 by Larry Rome of the University of Pennsylvania, He created a bag carried on a person’s back that also produces power from walking. The knee device does not produce as much electricity as the bag, but the bag requires the walker to carry a load of twenty to thirty kilograms.
1.. The second paragraph mainly talks about
A. who developed the device B. how the device works
C. several possible uses for the devices D. how much electricity the device can produce
2.. What is the disadvantage of the experimental version of the device?
A. It is too heavy for the walker to bear B. It is too complex for people to use

A. help housewives operate the washing machine
B. make it much easier for us to go online

Could the device, smartphone or PC, which you re using affect the moral decisions you make when using it? To test it, researchers presented multiple dilemmas to a sample set of 1,010 people. The participants were assigned a device at random.
One case of the questions participants were asked is the classic “trolley(有轨电车) problem”: A runaway trolley is headed towards five people tied up on a-set of train tracks. You can do nothing, resulting in the deaths of five people, or push a man off a bridge, which will stop the trolley. The practical response is to kill one man to save five lives, which 33. 5 percent of smartphone users chose, compared to 22.3 percent of PC users.
“What we round in our study is that when people used a smartphone to view classic moral problems, they were more likely to make more unemotional, reasonable decisions when presented with a highly emotional dilemma, “Dr Albert Barque-Duran, the lead author of the study, told City, University of London. “This could be due to the increased time pressure often present with smartphones and also the increased psychological distance which can occur when we use such devices compared to PCs.”
As for why the researchers started this study, Dr Barque-Duran noted, “Due to the fact that our social lives, work and even shopping take place online, it is important to think about how the contexts where we typically face moral decisions and are asked to engage in moral behavior have changed, and the impact this could have on the hundreds of millions of people who use such devices daily. “it’s clear that we need more research on how our devices affect our moral decision making because we’re using screens at an ever increasing rate.
1.Why did the author mention the trolley problem?
A.To introduce a difficult problem to readers.
B.To introduce the aim of carrying out the study.
C.To show an example of the questions in the study
D.To show the difficulty in dealing with dilemmas.
2.How do the smartphone users of the study behave in dealing with emotional dilemmas?
A.Calmly. B.Cruelly.
C.Hesitantly. D.Enthusiastically.
3.Dr Albert believes that compared with PCs, smartphones .
A.help people bear more pressure
B.help people make decisions quick
C.make people feel more mentally distant
D.make people stay happier to solve problems
4.What can we infer from the text?
A.Shopping online has a great effect on making moral decisions.
B.The people using smartphones are more than those using PCs.
C.People who often use smartphones or PCs always meet with dilemmas,
D.It is common for people to be involved in making moral decisions in daily life.

A new study has shown how computers and robots powered by artificial intelligence can read human eye movements to "read" human personalities.
The eyes, they say, are the windows to the soul. And if that is true, computers and robots powered by sophisticated(复杂的)artificial intelligence algorithms(算法)may soon have the ability to peer into your soul. That is the result of a new study on the connection between eye movements and personality, conducted by neuroscience researchers based at the University of South Australia and Published in the scientific Journal Frontiers in Neuroscience.
"Eye movements during an everyday task predict aspects of our personality," wrote the researchers, led by University of South Australia neuroscientist Tobias Loetscher, whose team follows 42 study subjects around the university campus recording their eye movements, then determines their personality traits(特点)with "well-established questionnaires" for determining personality type, according to a summary of the study published by the site Science Daily.
The researchers fed the data into their Al algorithms and found that computers running the algorithms were able to record human eye movements and immediately determine a person's major personality traits, such as "neuroticism, extraversion(外向),agreeableness, conscientiousness, as well as perceptual(感知的)curiosity", the scientists wrote.
"The new findings could improve the way human beings interact with their computers and other high-tech devices, even robots, allowing for more natural and realistic social interactions with machines," Loetscher said.
"People are always looking for improved, personalized services. Today's robots and computers are not socially aware so they cannot adapt to non-verbal information," Loetscher said in a statement quoted by Indian Express. This research provides opportunities to develop robots and computers so that they can become more natural, and better at interpreting human social signals."
The study revealed previously undiscovered relations between specific personality characteristics and specific eye movement tendencies, according to a summary in Britain's Daily Mail newspaper.
1.What do the underlined words "peer into" in Paragraph 2 probably mean?
A. understand B. stare at
C. search for D. concern about
2.How did the researchers conduct the research?
A. It was carried out in a lab.
B. 42 subjects' eye movements were recorded.
C. The students' daily movements were tracked.
D. Its subjects' personalities were determined by computer.
3.According to Tobias Loetscher, what can we know?
A. Robots and computers are socially conscious.
B. People care less about improved, personalized services.
C. Today's robots and computers can accustom to non-verbal information.
D. The discovery will improve the interaction between human beings and machines.
4.What can be a suitable title for the text?
A. Human Personality Traits
B. What Human Eye Movements Are
C. Tell Personalities by Eye Movements.
