Thirteen vehicles lined up last March to race across the Mojave Desert , seeking a million in prize money . To win , they had to finish the 142-mile race in less than 10 hours . Teams and watchers knew there might be no winner at all , because these vehicles were missinge a key part drivers .

DARPA , the Defense Advanced Research Projects Agency , organized the race as part of a push to develop robotic vehicles for future battlefields . But the Grand Challenge , as it was called , just proved how difficult it is to get a car to speed across an unfamiliar desert without human guidance . One had its brake lock up in the starting area . Another began by throwing itself onto a wall . Another got tied up by bushes near the road after 1.9 miles .

One turned upside down . One took off in entirely the wrong direction and had to be disabled by remote (远距离的) control . One went a little more than a mile and rushed into a fence ; another managed to go for six miles but stuck on a rock . The “winner,” if there was any , reached 7.8 miles before it ran into a long , narrow hole , and the front wheels caught on fire .

“You get a lot of respect for natural abilities of the living things,” says Reinhold Behringer , who helped design two of the car-size vehicles for a company called Sci-Autonics . “Even ants (蚂蚁) can do all these tasks effortlessly . It’s very hard for us to put these abilities into our machines .”

The robotic vehicles , though with necessary modern equipment such as advanced computers and GPS guidance , had trouble figuring out fast enough the blocks ahead that a two-year-old human recognizes immediately , Sure , that very young child, who has just only learned to walk , may not think to wipe apple juice off her face , but she already knows that when there’s a cookie in the kitchen she has to climb up the table , and that when she gets to the cookie it will taste good . She is more advanced , even months old , than any machine humans have designed .

67．Watchers doubted if any of the vehicles could finish the race because        .

       A．they did not have any human guidance

       B．the road was not familiar to the drivers

       C．the distance was too long for the vehicles

       D．the prize money was unattractive to the drivers

68．DARPA organized the race in order to          .

       A．raise money for producing more robotic vehicles

       B．push the development of vehicle industry

       C．train more people to drive in the desert

       D．improve the vehicles for future wars

       B．can take part in a race across 142 miles with a time limit

       C．can show off their ability to turn themselves upside down

       D．can move from place to place without being driven by human beings

70．In the race , the greatest distance one robotic vehicle covered was          .

       A．about eight miles                                 B．six miles

       C．almost two miles                                 D．about one mile

71．In the last paragraph , the writer implies that there is a long way to go          .

       A．for a robotic vehicle to finish a 142-mile race without any difficulties

       B．for a little child who has just learned to walk to reach the cookie on the table

       C．for a robotic vehicle to deal with a simple problem that a little child can solve

       D．for a little child to understand the importance of wiping apple juice off its face

When you close your eyes and try to think of the shape of your own body, what you imagine (or rather, what you feel) is quite different from what you see when you open your eyes and look in the mirror. The image you feel is much vaguer（模糊的） than the one you see. And if you lie still, it is quite hard to imagine yourself as having any particular size or shape.

When you move, when you feel the weight of your arms and legs and the natural resistance of the objects around you, the “felt” image of yourself starts to become clearer. It is almost as if it were created by your own actions and the feelings they cause.

The image you create for yourself has rather strange proportions（部分）; certain parts feel much larger than they look. If you get a hole in one of your teeth, it feels enormous; you are often surprised by how small it looks when you inspect it in the mirror.

Although the “felt” image may not have the shape you see in the mirror, it is much more important. It is the image through which you recognize your physical existence in the world. In spite of its strange proportions, it is all one piece, and since it has a consistent(前后一致的) right and left and atop and bottom, it allows you to locate new feelings when they occur. It allows you to find your nose in the dark and point to a pain.

If the felt image is damaged for any reason—if it is cut in half or lost as it often is after certain strokes （中风）which wipe out recognition of one entire side –these tasks become almost impossible. What is more, it becomes hard to make sense of one’s own visual appearance. If one half of the “felt” image is wiped out or injured, the patient stops recognizing the affected part of his body. It is hard for him to find the location of feelings on that side, and, although he feels the doctor’s touch, he locates it as being on the undamaged side.

1.According to the passage the “felt” image        the mirror image.

    A．is precisely the same as         B．is as clear as

    C．often differens from             D．is always much smaller than

2.Which the following staterants is NOT true?

    A．The felt Image is much more important because it helps you locate new feelings.

    B．When you are in bed with your eyes closed, it is not easy to imagine your image.

    C．When you move, the “felt” image of yourself starts to become clearer.

    D．The “felt” image is not so important as the mirror image.

3.If a man loses the ability to recognize his right side,            .

    A．he can’t locate the doctor’s touch on his left side

    B．he can’t locate the doctor’s touch on his right side

    C．he loses his sense of touch on the left side

    D．he loses feeling on both sides

4.What is this passage mainly about?

    A．Stroke victims’ “felt” images     B．Stroke victims’ mirror images.

    C．The importance of “felt” images  D．The importance of mirror images.

ScienceDaily (May 28, 2010) --- Researchers at Oregon State University (OSU) have made important progress in work that should lead toward robots that can not only walk and run very well, but use little energy at the same time.
Studies are moving closer to designing robots that could do dangerous work, create prosthetic limbs（假肢）for humans that work much better than in the past, or even help some people who use wheelchairs to get “walking” abilities.
“Researchers have been working toward robot movement for a long time,” said Jonathan Hurst, a professor at OSU. “What we’ve done is to study what behavior is really possible for a robot.”
The movement of humans and other animals is difficult to copy. Using little energy, they can move easily over hard areas, and enjoy balance from muscles（肌肉）. They have different ways to deal with forces, such as holding something hard in place rigidly（牢牢地）, like the act of holding a cup of coffee level during a car ride. In their recent studies, the OSU researchers proved that these two abilities are mutually exclusive（相互排斥的）. Humans deal with this problem by using pairs of muscles. For a robot, the more it’s able to do one of these tasks, the less able it is to do the other.
Presently, robots that can walk and run must be as rigid as possible while walking. But this way uses a lot of energy. The OSU researchers are working toward something that has similar or better performance, but uses far less energy, and is closer to the abilities of animals.
“So there’s no reason why we shouldn’t be able to build robots with good movement ability,” Hurst said. “Clearly this might be useful in highly dangerous situations. But I could also see great improvements possible with prosthetic limbs that work much better than present technology. ”
