Albert Einstein died long ago. However, a group of researchers have created a robot which looks like the great scientist.  The robotic Einstein is very special because the researchers at the University of California, San Diego (UCSD) have taught their realistic robot to smile, frown and make other complex facial expressions. Scientists believe that babies learn to control their bodies through movements, including learning to speak. "We use the same idea to work out the problem of how a robot could learn to make realistic facial expressions," said Javier Movellan, director of UCSD's machine Feeling Lab. ks5u The San Diego researchers directed the Einstein robot's head to turn in all directions. The robot could see its expressions in a mirror and then use the software to provide data for machine-learning to match facial expressions to the movements of its small motors. Once the robot learned the relationship between facial expressions and the muscle movements, it learned to make facial expressions. Its head has about 30 facial feelings, and each is moved by a tiny motor connected to ht e skin by s sting. Although we've never met Albert Einstein, we have a feeling that the new robot isn't exactly a fair representation of now of the best minds of the 20th century. The figure does not have the grace of the great man, but it can recognize human expressions and react to them in the right way. In fact, if you smile at it, it will smile right back to you. "As far as we know, no other research group has used a robot to make realistic facial expressions," said computer scientist Tingfan Wu, a computer science PhD student who worked on a more exact facial expression robot. How does the robotic Einstein make the muscle movements?. A) Some software directs tiny motors to do it. B) It begins to do that after learning how to smile. C) The researchers move its muscles up and down. D) It learns to do that only with a mirror.

A metaphor is a poetic device that deals with comparison. It compares similar qualities of two dissimilar objects. With a simple metaphor, one object becomes the other: Love is a rose. Although this does not sound like a particularly rich image, a metaphor can communicate so much about a particular image that poets use them more than any other type of figurative language. The reason for this is that poets compose their poetry to express what they are experiencing emotionally at that moment. Consequently, what the poet imagines love to be may or may not be our understanding of love. Therefore, the poet's job is to enable us to experience it, to feel it the same way as the poet does. Let's analyze this remarkably simple metaphor concerning love and the rose to see what it offers. Because the poet uses a comparison with a rose, first we must examine the characteristics of that flower. A rose is impressive in its beauty, its petals are nicely soft, and its smell is pleasing. It's possible to say that a rose is actually a feast to the senses of sight, touch, and smell. The rose's appearance seems to border on perfection, each petal seemingly equal in form. Isn't this the way one's love should be?A loved one should be a delight to one's senses and seem perfect. However, there is another dimension added to the comparison by using a rose. Roses have thorns. The poet wants to convey the idea that roses can be tricky. So can love, the metaphor tells us. When one reaches out with absolute trust to touch the object of his or her affection, ouch, a thorn can cause great harm! "Be careful," the metaphor warns, "Love is a feast to the senses, but it can overwhelm us, and it can also hurt us and cause acute suffering." This is the poet's understanding of love--an admonition  . What is the point?Just this: It took almost 14 sentences to clarify what a simple metaphor communicates in only four words! That is the artistry and the joy of the simple metaphor. As is meant by the author, thorns of a rose   _  . A) add a new element to the image of love B) protect the rose from harm C) symbolize reduced love D) cause acute suffering

Chris Jones recently finished a very unusual journey. Our reporter Mary Owen met him at his home in south prefix = st1 /Londonand he told her all about the trip. Reporter: What gave you the idea to travel around Indiaon an elephant, Chris? Chris: Well, it all started 2 years ago when I was planning a trip to India. I visited a photographic exhibition of elephants and I realized that the only way to travel is on an elephant. Reporter: What did you do next? Chris: I flew to New Delhiand started looking for an elephant. I needed an elephant trained to    carry people. I didn't know anything about elephants, so I asked an expert for help. He taught me how to ride an elephant. He also helped me find an elephant. Reporter: Can you tell me about the journey? Chris: Well. I bought a female elephant called Tara for about $ 6000. We set off from New Delhia week later. We were heading to Sonepur in northernIndiawhere there is a big elephant market and I could sell Tara easily. And what a ride! Elephants can travel at about 6 miles an hour and Sonepur was more than 1,200 kim away. The journey took us 64 days! Reporter: Did you have any problems on your journey? Chris: Yes, a few. But nothing serious. On the third day, Tara hurt her foot. But that got better quickly. Also there was a log of heavy rain during the first week and we got very wet! Reporter: What happened when you reached Sonepur? Chris: My plan was to sell Tara. But by now I was very fond of her. I couldn't take her back to Britainand I didn't want to sell her at the market. By chance,I met some people who wanted an elephant for their national park. I knew that Tara would be safe with them, so I gave her to them. I was very sad to say goodbye. When Chris arrived at Sonepur market, he  _   . A) realized that he didn't really want to sell Tara B) visited a national park C) sold Tara to a national park D) decided to take Tara home with him
