试题详情

At a laboratory in Germany ,volunteers slide into a machine and perform simple tasks, such as deciding whether to add or subtract two numbers , or choosing which of two buttons to press.

They have no idea that scientists in the next room are trying to read their minds-using a brain scan to figure out their intention before it is turned into action.

In the past ,scientists had been able to detect decisions about making physical movements before those movements appeared .But researchers at Berlin's Bernstein Center for Computational Neuroscience claim they have now , for the first time ,identified people's decisions about how they would later do a high-level mental activity-in this case ,adding versus subtracting.

While still in its initial stages ,the techniques may eventually have wide-ranging implications for everything from criminal questioning to airline security checks.

The research,which began in July 2005,has been of limited scope:only 21 people have been tested so far.And the 71 percent accuracy rate is only about 20 percent more successful than random selection.

Still ,the research conducted at the Max Planck Institute for Human Cognitive and Brain Sciences in Leipzig ,about 150 kilometers southwest of Berlin ,has been generating strong interest in the scientific community.

In one study ,participants were told to decide whether to add or subtract two numbers a few seconds before the numbers were flashed on a screen . Meanwhile ,a computer captured images of their brain waves to predict the subject's decision-with one pattern suggesting addition, and another subtraction.

The team ,headed by Haynes ,began its research by trying to identify which part of the mind was storing intentions. They discovered it was found in the prefrontal cortex region by scanning the brain to look for bursts of activity when subjects were given choices.

Then they went about studying which type of patterns were associated with different intentions.

"If you knew which thought signatures to look for ,you could theoretically predict in more detail what people were going to do in the future," said Haynes.

75.Which of the following is true about the experiment at the laboratory?

A.The volunteers are asked to perform very complicated tasks.

B.Everything was explained to the volunteers before the experiment.

C.The volunteers cannot see the scientists while performing the tasks.

D.The volunteers started the experiment by pressing one of the two buttons.

76.Which of the following demonstrates the major breakthrough made by the German scientists?

A.By studying the subjects' brain waves , they know what physical movements they'll make.

B.By studying the subjects' brain waves, they know what mental task they'll perform.

C.By studying criminals' brain waves ,they can help find out whether they are lying or not.

D.By studying passengers' brain waves ,they can help find out who intends to make trouble.

77.In the research which began in July 2005 only______subjects' brains were scanned and the accuracy rate was______.

A.21; 20% B.71;20% C.21;71% D.20;71%

78.The group of scientists in Leiqzig were doing______what the group in Berlin were doing.

A.similar research to B.better research than

C.completely different things from D.a less satisfactory job than

79.The term thought signatures in the last paragraph refers to______.

A.the subjects' intentions B.the subjects' physical movements

C.parts of the human brain D.the human brain wave patterns

80.From the information in the passage, it can be concluded that in the future______.

A.the intentions of people can be predicted accurately

B.it's impossible to predict accurately the intentions of people

C.no one in the world will dare to tell lies to other people

Researches at Johns　 Hopkins University's. Applied Physics laboratory　 ( APL)　 in Laurel , Maryland have designed a new human-like robot, Its name is Robo Sally. The machine can be controlled from a distance and can he used to do work that is dangerous for human beings.
　　　 Roho Sally has two long arms with human-like hands. She can use her fingers to pick up　 small objects .examine them in detail and do most things that human hands can do Each finger　 contains a tiny motor capable of squeezing 20 pounds of pinch foree ,.enough to defuse a bomb　 under the direction of an operator. She sits on a metal base with wheels that let her move around. turn in tight spaces and climb over small objects, .
　　　 Mike McLoughlin is the main investigator for the Applied Physics Laboratory's Prosthetics　 Program. "The purpose of that program is to develop prosthetic arms that have all the capability　 of your natural arms .and you do all the complex motions that we can do with the natural arm- with the robot. "
　　　 It was a difficult job. Mr. McLoughlin says the device had to have many small motors to。 have the ability to do what a human hand does; It　 also needs to have human-like strength. The　 thumb was especially difficult because it permits the hand .to hold objects. And everything had.　　 to fit into a space about the size of a human hand.
　　　 The next problem　 .he says .was to figure out how to control the artificial hand. " So we had　　 to figure out how to make the connection between the brain and this arm.
　　　 For search-and-rescue duties.Roho Sally will be operated by a human being using a wire- less machine that is far from the robot. The operator will also wear special gloves and glasses.　 The glasses permit the operator to see the robot's hands .even though they are far away.
　　　 Mr. McLoughlin says this kind of robots could be used in what he calls "dull , dirty or dan- gerous" situations where fine human finger movements are required. He says the technology is　 not ready for everyday application .but he predicts that within five years we will see some won-　 derful improvements.
1.The underlined word " defuse"　 in Paragraph 2 is closest in meaning to "_________".
A. remove　　　　　　　 B. discover　　　　　　　　 C. equip　　　　　　　　　　 D. produce
2.According to Paragraph 2.which picture is Robo Sally?
3.What can we learn ahout the prosthetic arms according to the passage?
A. They are expected to function as well as natural ones.
B. They have many large motors controlled by robots.
C. They have human-like strength to control the robot.
D. They are connected with human brains.
4.Which of the following is true about Robo Sally according to Mr. McLoughlin?
A . Its operator doesn't need　 any　 equipment.
B. It has been Widely used in everyday life in the USA.

A machine that takes sweat-laden (浸满汗水的) clothes and turns the sweat into drinking water is in use in Sweden. The machine makes the clothes turn round quickly, heats them to remove the sweat, and then passes the steam through a kind of special material to make purified water.
Since it has been brought into use, its creators say more than 1000 people have drunk others’ “sweat” in Gothenburg. They add the liquid is cleaner than local tap water.
The device was built for the United Nations’ child-focused charity UNICEF to promote a campaign highlighting the fact that 780 million people in the world lack access to clean water.
The machine was designed and built by the engineer Andreas Hammar, known locally for his appearances on TV tech show “Mekatronik”. He said the key part of the sweat machine was a new water purification part developed by a company named HVR.
“It uses a technique called membrane distillation (膜蒸馏),” he told the BBC. “We use a special kind of material that only lets steam through but keeps bacteria, salts, clothing fibers and other things out. They have something similar to the International Space Station, but our machine is cheaper to build. The amount of water it produces depends on how sweaty the person is, but one person’s T-shirt typically produces 10ml, about a mouthful.”
The device has been put on show at the Gothia Cup-the world’s largest international youth football tournament. Mattias Ronge, chief executive of Stockholm-based advertising agency Deportivo, said the machine had helped raise awareness for UNICEF, but in reality had its limitations.
“People haven’t produced as much sweat as we hoped – right now the weather in Gothenburg is lousy,” Mattias Ronge said. “So we’ve equipped the machine with exercise bikes and volunteers are cycling like crazy. Even so, the demand for sweat is greater than the supply. And the machine will never be produced in large numbers, since there are better solutions out there such as water purifying pills.”
1.Which of the following is the disadvantage of the sweat machine?
A. It takes too long for the machine to produce water.
B. The amount of water the machine produces is rather limited.
C. It costs a large amount of money to build the machine.
D. The water processed by the machine is not clean enough.
2.UNICEF is mentioned in the text to ________.
A. show how the sweat machine works
B. explain why the sweat machine was invented
C. show the importance of the United Nations
D. tell us who invented the sweat machine
3.What did Mattias Ronge think of the sweat machine?
A. It could only be used in summer.
B. It did not work at all.
C. It was not worth popularizing.
D. The water it produced tasted sweet.
4.The text is written mainly to tell us that ______________.
A. a machine which turns sweat into drinking water is invented
B. 780 million people in the world lack access to clean water
C. a better solution to purifying dirty water is discovered
D. the pill which turns dirty water into clean water is produced

Friedrich Dobl, a Yugoslav working in Germany, was fed up with traffic jams. At long weekends and holiday times when he wanted to get him quickly he always found himself behind hundreds of other cars moving slowly along the notorious foreign workers’ route through Germany and Austria.

How easy it all was for police and emergency services. A siren, a flashing light? And like magic everyone was out the way. Going home from work one night he passed a garage. And there in front of him was the answer to his problems. An old ambulance(救护车) was for sale. The red cross had been removed. But not the flashing light, and the siren. He tried the light. It flashed magnificently. He tried the siren. That too sounded impressive. He bought the ambulance and opened up for himself a dream world of motoring. It began early in the morning, all his luggage in the back of the ambulance and motorway in Germany looking reasonably clear. Soon, as always, a long line of traffic appeared ahead. He switched on the flashing light and set off the siren. Cars swiftly slowed and pulled off the fast lane. Other cars stopped and drivers waved him ahead to an open road all his own. In record time he crossed the border into Austria. The big bluff was working. Police even waved him through the confusion caused by an accident.

But then the Yugoslav made his big mistake. Until then he had only stopped for petrol. Now he was driving past a real accident, lights flashing , to late realize that it was not another traffic jam as he assumed. They stopped him, and after hearing the story of his ride across two countries fined him 12. 5 pounds.

1.At long weekends and holidays Friedrich Dobl used to ____.

A．drive home in Germany

B．get caught in terrible traffic jams

C．meet other foreign workers

D．get to the place where he worked by a special quick route

2.Why did he decide to buy the ambulance?

A．because he had always wanted one

B．because he wanted to resell it at a higher price

C．because he liked the siren and the flashing light

D．because he knew that other traffic would get clear of the way for an ambulance.

3.The red cross had been removed ____.

A．but he soon put up a new one

B．because the vehicle did not look like an ambulance any more

C．so he asked the garage to paint another one on

D．but the siren and the flashing light still worked
