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

"Equal pay for equal work" is a phrase used by the American women who feel that they are unfairly treated by society. They say it is not right for women to be paid less than men for the same work.
Some people say men have more duties than women. A married man is thought to earn money to support his family and to make the important decision, so it is right for them to be paid more. Some are even against married women working at all. When wives go out to work, they say, the home and children are given no attention to. (80) If women are encouraged by equal pay to take full-time jobs, they will be unable to do the things they are best at doing: making a nice home and bringing up children.
Women who disagree say they want to escape from the limited place which society wishes them to fill and to have freedom to choose between work and home life, or a mixture of the two. Women have the right not only to equal pay but also to equal chances.
The women use the phrase "equal pay for equal work" to ask society to _________.
A．pay men less than women
B．give Women harder work
C．pay men and women the same amount of money for the same work
D．pay people more who do harder work

Questions 31 to 35 are based on the following passage. Clothes play a critical part in the conclusions we reach by providing clues to who people are, who they are not, and who they would like to be. They tell us a good deal about the wearer’s background, personality, status, mood, and social outlook.
Since clothes are such an important source of social information, we can use them to manipulate people’s impression of us. Our appearance assumes particular significance in the initial phases of interaction that is likely to occur. An elderly middle class man or woman may be alienated (疏远…) by a young adult who is dressed in an unconventional manner, regardless of the person’s education, background, or interests.
People tend to agree on what certain types of clothes mean. Adolescent girls can easily agree on the lifestyles of girls who wear certain outfits (套装), including the number of boyfriends they likely have had and whether they smoke or drink. Newscasters, or the announcers who read the news on TV, are considered to be more convincing, honest, and competent when they are dressed conservatively. And collage students who view themselves as taking an active role in their inter-personal relationships say they are concerned about the costumes they must wear to play these roles successfully. Moreover, many of us can relate instances in which the clothing we wore changed the way we felt about ourselves and how we act ed. Perhaps you have used clothing to gain confidence when you anticipated a stressful situation, such as a job interview, or a court appearance.
In the workplace, men have long had well defined precedents and role models for achieving success. It has been otherwise for women. A good many women in the business world are uncertain about the appropriate mixture of “masculine” and “feminine” attributes they should convey by their professional clothing. The variety of clothing alternatives to women has also been greater than that avail able for men. Male administrators tend to judge women more favorably for managerial positions when the women display less “feminine” grooming (打扮)-shorter hair, moderate use of make up, and plain tailored clothing. As one male administrator confessed, “An attractive woman is definitely going to get a longer interview, but she won’t get a job.”
第31题：According to the passage, the way we dress ________.
A) provides clues for people who are critical of us
B) indicates our likes and dislikes in choosing a career
C) has a direct influence on the way people regard us
D) is of particular importance when we get on in age

We know that many animals de not stay in one place. Birds, fish and other animals move from one place to another at a certain time. They move for different reasons: most of them move to find food more easily, but others move to get away from places that are too crowded.
When cold weather comes, many birds move to warmer places to find food. Some fishes give birth in warm water and move to cold water to feed. The most famous migration (迁移) is probably the migration of fish, which is called "salmon". This fish is born in fresh water but it travels many miles to salt water. There it spends its life. When it is old, it returns to its birthplace in fresh water. Then it gives birth and dies there. In northern Europe, there is a kind of mouse. They leave their mountain homes when they become too crowded. They move down to the low land. Sometimes they move all the way to the seaside, and many of them are killed when they fall into the sea.
Recently, scientists have studied the migration of a kind of lobster (龙虾). Every year, when the season of bad weather arrives, the lobsters get into a long line and start to walk across, the floor of the ocean. Nobody knows why they do this, and nobody knows where they go.
So, sometimes we know why humans and animals move from one place to another, but at other times we don't. Maybe living things just like to travel.
Most animals move from one place to another at a certain time to ______.
A．give birth
B．enjoy warmer weather
C．find food more easily
D．find beautiful places
