Suppose you are a Spanish and live in Madrid. One day when you’re walking along the street, thinking about your own business, all of a sudden a stranger walked towards you with a smile on his face. After stopping you, he takes out a small electronic device from his pocket, holds it close to his mouth and speaks slowly into it, saying in English: "Excuse me, where is the restaurant" Then what would you do after hearing that I believe there would be three different kinds of response—some would run away quickly; some would call the police for help; and others would listen carefully to the sound from the device which said in Spanish, "Por favor donde eatáel restaurante"The most properly response may be the last one because the person standing in front of you is probably only a tourist trying to amuse himself. It is said that the device is the world’s first portable transistor—a hand-held microcomputer that can converts one spoken language into another simultaneously.The four-pound product is called the Voice, which is battery-operated, and it was invented by Advanced Products and Technologies—a well-known American electronics company. When the Voice was first introduced in the United States in late April at a price of over $ 1,000, it could convert spoken English into four other languages involving Italian, French, German and Spanish. The product includes separate cartridges (盒式储存器) for each of the four languages, which can be changed in an interactive way whenever the users need. The item will be seen on European market soon after the U. S.The Voice uses a microchip (微型集成块) and artificial intelligence to translate various languages. It is started by voice command and outputs voices through a built-in speaker. Then the user can make a statement or ask a question, the Voice repeats immediately what has been said in another specified language. The purpose that the stranger spoke into the Voice is ().

听下面一段对话，回答第18至第21题。W: Right, well, in the studio this morning, for our interview spot is Peter Wilson. Peter works for Green Peace. So, Peter, welcome.M: Thanks a lot. It’s good to be here.W: Great! Now, Peter, perhaps you can tell us something about Green Peace and your job there.M: Sure. Well, I’ll start by telling you roughly what Green Peace is all about. I actually work in London for the Green Peace organization. We’ve been going for a few decades and we’re a non-violent, non-political organization. We’re involved in anti-nuclear activity, conservation and protection of animals and protection and support of our eco-system. I’m the action organizer and arrange any protests.W: Right! A pretty important role, Peter. What sort of protest would you organizeM: Well, recently we’ve been involved in anti-nuclear campaigns. I, personally arranged for the demonstration against radioactive waste dumping in the Atlantic Ocean. We’ve got a few small Green Peace boats that we harass the dumping ship with.W: Say Hold on, Peter. I thought you said your organization was non-violent. What do you mean by "harass"M: Well, we circle round and round the ships and get in the way when they try to dump the drums of nuclear waste in the sea. We talk to the men and try to change, you know, yell at them to stop. We generally make ourselves as much of a nuisance as possible.M: Well, people may think differently of your methods, but there’s no doubt you’re doing a great job. Keep it up and good luck. And thanks for talking with us. What is the woman’s attitude towards the campaigns organized by Green Peace().
M: How does Nancy like the new dress she bought in RomeW: She said she would never have bought an Italian style dress if she had known Mary had already got such a dress. What do we learn from the conversation().
W: I found the lounge such a cozy ptace to study in. I really like the feeling in sitting on the sofa and doing the reading.M: Well, for me the hardest part about studying here is staying awake. What does the man imply().
Einstein, known as a famous physicist, went to Gottingen to give a lecture at the (26) invitation of the mathematical physicist David Hilbertin 1915. He was particularly (27) for this visit because it would give him a golden opportunity to explain the intricate relativity to him. The visit turned (28) a great success, and he told one of his friends excitedly that he had convinced Hilbert of the theory of relativity.Amid all of Einstein’s personal worries at that time, a new scientific (29) would emerge. He was trying his utmost to find the right equations that would (30) his new concept of gravity, ones that would (31) how objects move (32) space and how space is bent by objects. By the end of the winter, he was (33) to find out the mathematical approach he had been pursuing (34) almost three years was incorrect. And now there was a fierce (35) Einstein discovered that Hilbert had (36) theories from Einstein’s lecture and would come up (37) the correct equations first.It was an arduous task at that time. Although Einstein performed better in physics than Hilbert, Hilbert was the better mathematician. So later Einstein (38) himself to (39) after equations, proofs, and (40) so that he could return to an earlier mathematical strategy and give as lectures to Berlin’s Prussian Academy of Sciences.His first lecture (41) on Nov. 4, 1915, and he explained his new approach during the lecture, (42) he admitted he did not yet obtain the precise mathematical formulation. Einstein was also (43) engaged in revising his equations to compete with Hilbert. Worried (44) being scooped(抢先) ,he sent a copy of his lecture to Hilbert. "I am curious to know whether you will make use of this new solution," Einstein noted with a touch of (45) 41().
