Predictions of many robots in industry have yet come true. For ten years or more, manufacturers of big robots have explained how their machines can make industry more competitive and productive. The maker for        robots is oversupplied now, and the driving force of the robotics revolution is        to be with the maker of machines that handle a few kilos at most.
"Heavy-robot manufacturers are in some difficulty        finding customers. They are offering big        just to get in the door. There has been a      growth everywhere in the numbers of robots, so we admit we are either deceiving        or that the market is slowly growing，" said John Reekie, chairman of Colen Robotics. "The following things must hap-pen        the robotics revolution to occur. We must achieve widespread robot literacy.        there has been a computer        program, there must be a robot literacy program.      ，some kind of artificial intelligence needs to be        ”
Colen makes educational robots and machine tools. It is small        with companies like ASEA or Fujitsu Fanuc. But Colen with others in departments in universities such as Surrey, Manchester, and Dur-ham possesses an advantage        the giants. The big companies sell very expensive        to businesses with expert knowledge in automation. The      companies make robots for teaching people, and now they have realized that there is a need for small，          robots that they can meet.
The little companies either bring their educational machines        an industrial standard or design from the start. One technique that they all adopt is to choose            （18）components where possible. The major cost of making        their models is the electronics, which will fall in price. There is        scope for reductions in mechanical costs. The use of standard parts，which are easily replaced, should give these robots a mechanical life of something in the order of five years.

Scientists are racing to build the world's first thinking robot. This is not science fiction： some say they will have made it by the year 2020，Carol Packer reports.
Machines that walk, speak and feel are no longer science fiction. Kismet is the name of an android (人形机器人）which scientists have built at the Massa-chusetts Institute of Technology (MIT). Kismet is different from the traditional robot because it can show human emotions. Its eyes, ears and lips move to show when it feels happy, sad or bored. Kismet is one of the first of a new generation of androids—robots that look like human beings—which can imitate human feelings. Cog, another android invented by the MIT, imitates the action of a mother. However, scientists admit that so far Cog has the mental ability of a two-year-old.
The optimists (乐观主义者） say that by the year2020 we will have created humanoids (人形机器人） with brains similar to those of all adult human beings. These robots will be designed to look like people to make them more attractive and easier to sell to the public. What kind of jobs will they do? In the future, robots like Robonaut , a humanoid invented by NASA, will be doing dangerous jobs, like repairing space stations. They will also be doing more and more of the household work for us. In Japan, scientists are designing androids that will entertain us by dancing and playing the piano.
Some people worry about what the future holds：Will robots become monsters(怪物）？ Will people themselves become increasingly like robots? Experts predict that more and more people will be wearing micro-computers，connected to the Internet, in the future. People will have micro-chips in various parts of their body, which will connect them to a wide variety of gadgets (小装置）. Perhaps we should not exaggerate (夸大）the importance of technology, but one wonders whether, in years to come，we will still be falling in love, and whether we will still feel pain. Who knows?

An underwater robot that can hear the calls of whales, and to help ships to avoid them, has just been successfully tested in the Bahamas.
The scheme relies on a fish-shaped glider that moves freely through the ocean. It can dive down as far as 200 meters below the surface and direct itself by shifting a weight from fore to aft. A microphone attached to the bottom of the glider can pick up calls from all whales, including the high frequency call of the beaked whale, which until now has been difficult to detect. The glider returns periodically to the surface to radio its data back to base, or if that's too far away, it can call a satellite phone and send its information anywhere in the world.
"We are entering a new era of underwater sensing' says Jim Theriault of Defence Research and Development Canada, in Dartmouth, Nova Scotia who ran the trial. "We can put a glider in the Bahamas and monitor it in Nova Scotia. ”
The hope is that naval or other ocean-going operations that use sonar (声呐）will be able to more easily track where whales are, and so avoid using their noisy equipment when they are close by. There is circumstantial evidence that sonar can upset whales and a number of strandings (搁浅）have been seen shortly after naval sonar operations. “We're trying to lower the potential risk by knowing the animals are there，” says Theriault.
The shape of the underwater robot is like __________

The underwater robot is built to __________.

To radio its data back to base, the robot has to __________

 The four books are all about __________.

 Who is the author of Bears Discover Fire"!

 Which of the following books is most probably difficult to buy?

 What can we learn from the above information?

Among the most popular books being written today are those which are usually classified as science fiction. Hundreds of titles are published every year and are read by all kinds of people. Furthermore, some of the most successful films of recent years have been based on science fiction stories.
It is often thought that science fiction is a fairly new development in literature, but its ancestors can be found in books written hundreds of years ago. These books were often concerned with the presentation of some form of ideal society, a theme which is still often found in modern stories.
Most of the classics of science fiction, however, have been written within the last one hundred years. Books by writers such as Jules Verne and H. G. Wells, to mention just two well-known authors, have been translated in many languages. Modern science fiction writers don't write about men from Mars or space adventure stories. They are more interested in predicting the results of technical developments on society and the human mind, or in imagining future worlds which are a reflection of the world which we live in now. Because of this their writing has obvious political undertones.
In an age where science fact frequently over-takes science fiction, the writers may find it difficult to keep ahead of scientific advances. Those who are sufficiently clear-sighted to see the way we are going, however, may provide a valuable lesson on how to deal with the problems which society will inevitably face as it tries to master its new technology and come to terms with a continually changing view of the world.
 Most of the classics of science fiction have been written within __________.

 Modern science fiction writers are interested in __________

 Science fiction writers may provide a valuable les-son on how to deal with the problems of __________

Robots at the World Expo 2010 Shanghai play football，practice tai chi , play the violin, prepare Chinese dishes and care for the elderly. Scrap metal robots created by a Chinese farmer can pour tea and paint pictures.
Global designers of robots are making them more capable, powerful and affordable, so they will play more roles in more sectors, from manufacturing to health care, and they can help around the house.
Now Toyota, the world's biggest car maker, and Canon, the biggest camera maker, have joined research and development to make robots a practical reality, like a PC.
The Expo Shanghai is a place where China can learn about advanced robotics, and a stage for made-in-China robots.
Developers are taking robots from “Star Wars”and top laboratories and putting them into the industrial sector, even in consumer markets. They are used in health care, computer programming, manufacturing and culture.
The goals are to add more practical functions and to cut prices, and lower cost comes with higher volume.
“The World Expo is a unique opportunity to demonstrate French technology，”says Bruno Maisonnier，chief executive of Aldebaran Robotics, which shows Nao robots in the France Pavilion.
More than 700 Nao robots, which cost 1,000 to12,000 euros (US $ 14,640) each, are sold mainly to research organizations, including 60 to 70 in China.
The French-based company aims to promote robots in the general public market starting from late2011，with entertainment or learning functions at a"reasonable price", according to Maisonnier.
Visitors to the Japan Pavilion are struck by Toyota's dextrous Partner Robot playing the Chinese folk song Jasmine Flower on the violin. Other robots play other instruments, but the violin is the most complicated.
Many people were so enchanted by the robotic musician that they overlooked other Partner Robots, designed to be personal assistants especially for Japan's aging population. One can even carry passengers.
 Robots at the World Expo 2010 Shanghai are designed to be __________

 Toyota and Canon have joined research and development to make robots, which shows __________

 From the passage we can see Nao robots are designed __________

 What's the best title of the passage?

Researchers are placing robotic dogs in the homes of lonely old people to determine whether they can improve the quality of life for humans. Alan Beck, an expert in human-animal relationship, and Nancy Edwards, a professor of nursing, are leading the animal-assisted study concerning the influence of robotic dogs on old people's depression, physical activity, and life satisfaction. “No one will argue that an older person is better off being more active, challenged, or stimulated, Edwards points out. "The problem is how we promote that, especially for those without friends or help. A robotic dog could be a solution. ”
In the study, the robot, called AIBO, is placed for six weeks in the houses of some old people who live alone. Before placing AIBO in the home, re-searchers will collect baseline data for six weeks. These old people will keep a diary to note their feelings and activity before and after AIBO. Then, the researchers will review the data to determine if it has inspired any changes in the life of its owner.
“I talk to him all the time, and he responds to my voice，” says a seventy-year-old lady, “When I'm watching TV, he'll stay in my arms until he wants down. He has a mind of his own. ”
The AIBOs respond to certain orders. The researchers say they have some advantages over live dogs, especially for old people. Often the elderly are disabled and cannot care for an animal by walking it or playing with it. A robotic dog removes exercise and feeding concerns.
"At the beginning, it was believed that no one would relate to the robotic dog, because it was metal and not furry，" Beck says. "But it's amazing how quickly we have given up that belief. "
"Hopefully, down the road, these robotic pets could become a more-valuable health helper. They will record their masters' blood pressure, oxygen levels, or heart rhythms. AIBOs may even one day have games that can help stimulate older people's minds. "
The purpose of Beck and Edwards' study is to __________.

 In the research, the old people are asked to __________

 What is the advantage of AIBO over live dogs?

 The author seems to suggest that the future robotic dogs may __________.

        Many things can become distractions (分散注意力） Your ability to focus your mind, emotions, and physical movements will directly influence your success. Staying focused on the task at hand can be easier said than done. Here are some powerful techniques that can help you improve your ability to focus.
For physical control, it helps to have a constant exercise schedule.     Exercising helps you gain better command of your body, and even goes beyond the body, giving you more flexibility not justphysically but also emotionally and mentally. When you feel more comfortable in your body, you increase your self-confidence, which helps you feel more relaxed.
For mental control, meditation (沉思、；冥想）does the task.      It's easy to get distracted by things in your background, but in order to perform well you have to maintain a high degree of focus. When you relax your thoughts it trains your mind to deal effectively with outside distractions so you can stay centered on what matters most at that moment.
      It prevents you from overreaction and also from overacting. When your emotions settle down, you gain greater awareness of the environment you're in, and feel calm and in control.
  The good thing is that self-control can be developed. Start exercising frequently, get yourself into meditation, and start to feel positive changes in your career and your life in general.

E. Your emotions are well served by meditation as well.
F. Focus is an important part of success and achievement in general.
G. It helps block out all the noise and activities that are going on around you.

As a student, I hate the exam system we are now used. This system may be a good way to test a student's memory, and it can tell you nothing about a student's ability. It does not good to students or teachers. As soon as a child begins the school, he enters a world of exams that will decide his future. In fact a good exam system should train a student to think himself, but it now does something like that. So students are encouraged to remember what is taught. The students who comes out first in the exam often may not be the best in their studies. It must be some better way to test a student's true ability except knowledge. And that is where we should do right now.
