The Robot Man
According to Hans Moravec,universal robots will take over all the physical activities that we engage in,leaving us with little to do.Moravec sees four generations on the road to true universal robots. The first generation will be here by 2010 and will consist of free-ranging robots that can navigate by building an internal mental map of their surroundings.In new situations they'll be able to adapt,unlike today's mobile industrial robots.These robots will have the computing power to cope with simple speech and text recognition,and will be used for tasks such as domestic clean-ing.
The second generation will arrive around 2020 and will be distinguished by the ability to learn .Second generation robots are programmed with sets of primitive tasks and with feedback that provide"pleasure"and"pain"stimuli .For example,a collision provokes a negative response,a completed task would be positive.
Move forward another ten years to 2030 and you get to generation three.This robot can build internal simulations of the world around it. Before beginning a task,it can imagine what will happen in order to predict problems.If it has a free moment,it can replay past experiences and try variations in order to find a better way of如ing things next time .It could even observe a person or another robot performing a task and learn by imitation.For the first time,we have here a robot that can think.
By the time we get to generation four in 2040,Moravec predicts that robots will be able to: match human reasoning and behaviour;generalise abstract ideas from specific experience;and, conversely,compile detailed plans of action from general commands such as"earn a living"or "make more robots".
The Moravec manifesto（宣告）runs something like this. As robots start to become useful in generation one,they'll begin to take on many tasks in industry.Driven by the availability of this cheap and tireless labour force,the economy will boom and the demand for robots will grow so rapidly that they will soon become lowcost commodity items.So much so that they'll move into the home,where the domestic robot will relieve us of many chores.
With increasing automation in generations two and three,the length of the average working day will plummet,eventually to near zero. Most people will be unemployed as robots take over not just primary industry,but the service economy too.Moravec sees the fourth generation as an opportunity to surpass our human limitations.
These future machines will be our"mind children".Like biological children of previous generations,they will embody humanity's best hope for a long-term future.

The author's main purpose is to______.
A: describe the life of Hans Moravec
B: support the view that robots will play a major role in our life
C: make fun of the views of Hans Moravec
D: get people prepared for the threat of future robots

Chimpanzees
1 Chimpanzees（黑猩猩）will soon be extinct（灭绝）.If the present rate of hunting and habitat（栖息地）destruction continues, then within 20 years, there will be no chimpanzees living in the wild. But this is more than an environmental or moral tragedy（悲剧）.Chimpan-zee extinction may also have profound implications（含意）for the survival of their distant relatives一human beings.
2 In 1975 the biologist Marie-Claire King and Allan Wilson discovered that the human and chimpanzee genomes（基因组）match by ovet 98%. Compare this to the mouse, used as model for human disease in lab tests,which shares only 60% of its DNA with us.In fact, chimpanzees are far more similar to humans than they are to any other species of monkey. As well as resembling us genetically,chimps are highly intelligent and able to use tools.These facts alone should be enough to make protection of chimps an urgent priority（优先）.But there is another,more selfish reason to preserve the chimp.
3 The chimpanzees' trump card（王牌）comes in the field of medical research. Chimpanzees are so similar to humans that veterinarians（兽医）often refer to human medical text-books when treating them. Yet chimpanzees do show differences in several key areas.In parti-cular,chimps are much more resistant to a number of major diseases.It is this ability that is so interesting.
4 For example,chimps seem to show a much higher resistance than humans to HIV,the virus that causes AIDS. Indeed,their use as experimental animals in AIDS research has de-dlined because they are so resistant.
5 By sequencing the chimp genome and pinpointing（找到）the place where the chimpanzee DNA sequence differs from that of humans,scientists hope to be able to discover which part of the genetic code gives chimps their increased resistance to some diseases. This,they hope,will allow them to develop new and more effective treatments for the human forms of these diseases. Such treatments could include the production of new drugs or even the alteration（改变）of the human genetic sequence. The recently completed human genome sequencing project has shown that such an effort is now well within our reach.

The discovery of the genetic code of chimps will be helpful to______.
A: some human disease treatments
B: some diseases
C: human survival
D: human genomes
E: key areas

Exercise and Brain

Just as exercise strengthens the heart and lungs,bones and muscles,it may also power up the brain.A succession of scientific studies of animals implies that physical activity has a positive effect on mental functioning.
"It's clear that the brain benefits from exercise,"says brain scientist William Greenough of the University of Illinois at Urbana-Champaign.His studies with rats have demonstrated two primary effects of activity:Vigorous physical exercise provides the brain with more fuel,and skill-based ex-ercise increases the formation of connections in the brain, which, according to the proposals of some scientists,may make the brain better able to process information.
In one experiment,laboratory rats were separated into three groups.One group was exercised by running inside an automatic wheel,a second group improved their skills in a complicated obstacle course,and a third group was inactive.
"The animals that learned to go through the obstacle course exhibited a greater number of brain connections than the animals in the exercised or inactive groups,"Greenough said."In contrast, the animals that exercised inside the automatic wheel possessed a greater density of blood vessels in the brain than did either of the other two groups of animals."
Learning a new dance step may boost the brain in the same way that learning a language can, he says.And if the dance is a good physical exercise as well,the benefits multiply.Young brains may be especially able to boost brain power through exercise,suggested another of Greenough's experiments that showed the most significant changes in the brain occurred among rats that had been exercised when very young.And while animals aren't people,he says it is logical to make the inference that an effect found in rats may also apply to humans.
Human studies have focused primarily on older adults and suggest that regular exercise can improve the speed with which the brain processes information.Measurements made by Arthur Kramer at the University of Illinois demonstrated that inactive adults,aged 63 to 82,could hit buttons faster in response to a tone after they went through a 10-week water exercise course.A corresponding control group that didn't exercise showed no improvement.

Which statement is correct according to the passage?
A:The effect of exercises found in rats can not apply to people.
B:Changes in the brain occurred among young rats are more significant than those among adult rats.
C:Regular exercise can only improve the speed with which the older adults' brain processes information.
D:The author encourages people do more skill-based exercise instead of vigorous physical exercise.

Our research has focused on a drug which is so __________as to be able to change brain chemistry.

A.powerful
B.influential

资料：Demystifying how social and human-like robots work is vital so that we can understand and shape how they will affect our future, Dr Hatice Gunes will tell the Hay Festival next week. (1)
　　Fear mongering and myth-making about human-like and social robots is stopping us from engaging with the technology behind them and having an input into how they—and we—evolve, says Hatice Gunes, Associate Professor at University of Cambridge's Computer Laboratory. (2)
　　Dr Gunes will be speaking about her research at the Hay Festival on 1st June and says we need to move beyond sensationalist portrayals of human-like robot. Her Hay talk will centre on human robot interaction [ HRI] and how it can be used for our benefit, for instance, for helping children with autism learn how to read expressions and to stimulate the senses of elderly people in care. (3)
　　Dr Gunes will outline how HRI works. She says it has to be believable in order to be effective. That means robots’ appearance is very important. This is what has driven the development of humanoid robots with arms and aspects of a human face which can behave in a human-like way, for instance, moving their arms, legs and eyes. However, more important than appearance is their behaviour and emotional expressivity. Dr Gunes refers to the way we relate to Disney’s animated characters. “People believe in them because they can portray emotion,” she says. (4)
　　To achieve expressivity requires an understanding of how human emotions are portrayed and triggered. Scientists have been working on artificial emotional intelligence which enables new technology such as embodied agents and robots to both express and detect emotions, understanding non-verbal cues. Dr Gunes cites the work of Charles Darwin on the visual nature of emotions and how they can be mapped to various changes in facial expressions. (5)
　　Her research investigates how humanoids can be programmed not only to extract and respond to facial clues to emotions, but also to understand the context in which those emotions are expressed. That means they will be able to offer a response that is sensitive to specific contexts. (6)
　　Will robots ever be able to have emotions themselves though? Dr Gunes says there is no reason why not and questions what emotions are. The process of working with robots on artificial emotional intelligence unpicks the nature of our emotions, showing them to be a layering of different goals, experiences and stimuli. (7)
　　 Another area which scientists are looking at in their quest to improve humanoids’ believability is personality. Dr Gunes has done a lot of work on personality in telepresence robotics, robots controlled remotely by a human—a kind of 3D avatar. These can be used in many ways, for instance, by medical staff to offer remote home care. The medical person can be based anywhere and operate the robot through a virtual headset. Dr Gunes is interested in how people react to the teleoperator (the human controlling the robot remotely) who is present in robot form. Once again, both the robot’s physical appearance and behaviour are important and research shows that their personality needs to be task dependent. (8)
　　Dr Gunes says there remain some big challenges for scientists working on HRI, including how to process and combine all the different data they are gathering, how to modify their appearance and behaviour dynamically, and how to keep their power going 24/7. The major challenges, however, are to do with breaking down some of the myths and fears people have about humanoids. (9)
　　 Part of this is because they don’t understand the benefits humanoid robots can bring and why, for instance, they need to take on a human form and understand emotions. She says humanoids can be positive in terms of increasing trust and engagement among certain groups, such as the elderly; that humans tends to anthropomorphise technology in any event; and that robots can be programmed to be limited to positive emotions that promote altruism. (10)
　　“People tend to love or hate robots, but they don’t really know a lot abou

A.With the development of human robot interaction, robots ae now able to communicate with humans in an effective way.
B.Scientists have many challenges in developing robots, such as how to modify their appearance and behavior.
C.Human emotions enable robots to win the trust from human, especially the elderly and children.
D.It is important to help people understand robots in order to develop robots to human needs.
