Robot. It is a word that seems very modem. A word that creates a strong mental picture. A picture of something that looks and acts like a human. Robots are not human, of course. They are machines.
The word robot and robots themselves are less than 100 years old. But humans have been dreaming of real and imaginary copies of themselves for thousands of years. Early people made little human statues out of clay. And they cut wood and stone to look like humans.
What is the future of robots? The goal of scientists is to create a true humanlike robot. Some experts have described this robot of the future as one that can act independently with the physical world through its own senses and actions. Humans have the ability to see, hear, speak and solve problems. Engineers have built robots that have one or two of these abilities. But it takes a number of big expensive computers to make the robots work.
The biggest problem in creating a humanlike robot is copying human intelligence. The way the human mind works is almost impossible to copy. A simple computer can solve mathematical problems far beyond the ability of even the smartest human mind. But the human mind is better than a thousand supercomputers at speaking, hearing and problem solving. Several American and Japanese companies are working to develop the senses of sight and touch for robots. The development of these senses will make robots much more useful.
However, the most important human ability the most difficult to copy is problem solving. An intelligent robot must be able to change the way it acts when it faces an unexpected situation. Humans do it all the time. Computers must do it for robots. This means computers must have a huge base of information about many things. They must be able to find quickly the needed information in their systems. And they must make choices about how to act. So far, this is beyond the ability of computers.
According to the passage, however intelligent a robot may be, it______.
A.acts as an ordinary animal
B.is nothing but a machine
C.is viewed as a modem myth
D.is regarded as a human being

听力原文:W: Now that we are nearing the end of our last year of school, I am very concerned about finding a job.
M: Have you checked with the employment resource center here at school?
W: Yes, there were one or two promising leads, but I'm hoping to find something a little better than those. I have a list of the most prominent accounting firms. I plan on sending my resume to each of them.
M: Tom told me that he has mailed out twenty resumes already.
W: The job market is very tight this year. I'm afraid that there will be a lot of the graduating class that will have to settle for something less than they hoped for or go to a less desirable part of the country.
M: Bob and Joe have contacted a headhunter. They hope by using those professional services they will be able to find a good position.
W: I thought of doing that myself, because their fee is too high. They would want nearly half of my first six months' salary.
M: What about that accounting firm your father's company uses? Do you think he could give you a recommendation?
W: I hate to ask him to do that, but if my other leads don't work out, I'll ask him for help.
M: Networking the contacts you have is one of the best ways to find employment.

Women are quite often competent drivers, but they are very seldom consistently first class. At best they are a mild hazard, at【C1】______ potentially lethal.
A wise male driver will always give them plenty of roads and still be on the lookout for the【C2】______ to happen.
This【C3】______ has nothing to do with their lack of ability to cope with the【C4】______ complexities of the vehicles; it is due to an inherent【C5】______ which, in certain other circumstances, may be highly desirable,【C6】______ which, behind the wheel, is deadly. It is their【C7】 for talking. Women together in a car yield【C8】 ______ this need and when they talk they look into each other's faces. Simple words are【C9】______
It is necessary for them to see the expression which【C10】______ the words and so read the meaning the words left unsaid.【C11】______ two women in the front of a car repeatedly【C12】______ each other's attention from the road, and four represent an incredible danger【C13】______ the one nominally driving the car feels it necessary to see and hear not only what her companion is talking about but also, such is her【C14】______ , what those in the back are discussing in case it is anything【C15】______ which she can inject and add opinion, or in the hope of collecting fresh fuel to feed other fires on later【C16】______ .

Passage TwoQuestions 57~61 are based on the following passage. What’s hot for 2007 among the very rich? A $7. 3 million diamond ring. A trip to Tanzania to hunt wild animals. Oh, and income inequality.
Sure, some leftish billionaires like George Soros have been railing against income inequality for years. But increasingly, centrist and right-wing billionaires are starting to worry about income inequality and the fate of the middle class.
In December, Mortimer Zuckerman wrote a column in U. S. News & World Report, which he owns. “Our nation’s core bargain with the middle class is disintegrating, ”lamented (哀叹) the 117th-richest man in America. “Most of our economic gains have gone to people at the very top of the income ladder. Average income for a household of people of working age, by contrast, has fallen five years in a row. ” He noted that “Tens of millions of Americans live in fear that a major health problem can reduce them to bankruptcy. ” Wilbur Ross Jr. has echoed Zuckerman’s anger over the bitter struggles faced by middle-class Americans. “It’s an outrage that any American’s life expectancy should be shortened simply because the company they worked for went bankrupt and ended health-care coverage,” said the former chairman of the International Steel Group.
What’s happening? The very rich are just as trendy as you and I, and can be so when it comes to politics and policy. Given the recent change of control in Congress, the popularity of measures like increasing the minimum wage, and efforts by California’s governor to offer universal health care, these guys don’t need their own personal weathermen to know which way the wind blows.
It’s possible that plutocrats(有钱有势的人)are expressing solidarity with the struggling middle class as part of an effort to insulate themselves from confiscatory(没收性的)tax policies. But the prospect that income inequality will lead to higher taxes on the wealthy doesn’t keep plutocrats up at night. They can live with that.
No, what they fear was that the political challenges of sustaining support for global economic integration will be more difficult in the United States because of what has happened to the distribution of income and economic insecurity.
In other words, if middle-class Americans continue to struggle financially as the ultrawealthy grow ever wealthier, it will be increasingly difficult to maintain political support for the free flow of goods, services, and capital across borders. And when the United States places obstacles in the way of foreign investors and foreign goods, it’s likely to encourage reciprocal action abroad. For people who buy and sell companies, or who allocate capital to markets all around the world, that’s the real nightmare.
第57题:What is the current topic of common interest among the very rich in America?
A.The fate of the ultrawealthy people.
B.The disintegration of the middle class.
C.The inequality in the distribution of wealth.
D.The conflict between the left and the right wing

Elephants are perhaps the only animals that are hunted for their teeth. Elephant tusks, or very large teeth growing on either side of their mouths, are composed of a valuable material called ivory(象牙).
(78) An elephant uses its long, pointed tusks as tools for digging in the ground for food. He also uses them as weapons in combat.
The tusks of male elephants are usually large and heavy. In Africa, female elephants have long, light tusks. In India and other parts of southern Asia, female elephants have small, short tusks or none at all.
(79) Tusks in good condition are in great demand, and may sell for as high as two thousand dollars or more. Because of this, large numbers of elephants have been killed. Some countries have initiated (开始) methods to protect elephants. They have established elephant preserves, areas of land set aside for herds of elephants where no one is allowed to harm them. Elephants on the preserves are safe from ivory hunters.
Female elephants in India and southern Asia have ______ .
A.large and heavy tusks
B.small, short tusks or none at all
C.small and heavy tusks
D.long, light tusks

It is customary for adults to forget how hard and dull and long school is. The learning by memory of all the basic things one must know is a most incredible and unending effort. School is not easy and it is not for the most part very much fun, but then, if you are very lucky, you may find a real teacher. Three teachers in a lifetime are the very best of my luck. My first was a science and math teacher in high school, my second, a professor of creative writing at Stanford, and my third was my friend and partner, ED Rickets.
I have to believe that a great teacher is a great artist and that three are as few as there are any other great artists. It might even be the greatest of the arts since the medium is the human mind and spirit.
My three teachers had these things in common: They all loved what they were doing; they did not tell, but stimulated a burning desire to know. Under their influence, the horizons sprang wide and fear went away and the unknown became knowable.
I shall speak only of my first teacher because in addition to the other things, she brought discovery. She aroused us to shouting, book-waving discussions. She had the noisiest class in school and she did not even seem to know it. We could never stick to the subject. Our speculation (思绪) ranged the world. She breathed curiosity into us so that we brought in facts or truths shielded in our hands like captured fireflies (萤火虫).
She was fired, and perhaps rightly so, for failing to teach fundamentals. Such things must be learned. But she left a passion in us for the pure knowable world and she inflamed me with a curiosity which has never left. I have had many teachers who told me soon-forgotten facts but only three who created in me a new attitude a new hunger. What deathless power lies in the hands of such a person?
21. In the writer’s opinion, school life is usually .
A. exciting B. interesting C. tiresome D. challenging
22. We can infer from Paragraph 2 that .
A. it is easy to find great artists as well as great teachers.
B. there are few great teachers but many great artists.
C. the greatest artists are not easy to find; nor are the greatest teachers.
D. being a great teacher is a great art to learn because teachers spread knowledge.
23. In the writer’s opinion, a good teacher should .
A. teach students the fundamental things
B. stick to one subject and be strict with students
C. teach students the knowledge ranging the world
D. arouse students’ curiosity and desire for the world
24. The writer’s first teacher was dismissed mainly because .
A. her class was the noisiest in school
B. she did not teach basic knowledge in class
C. she let students shout and wave books in class
D. she did not know how to teach basic knowledge effectively
