[主观题]

People appear to be born to compute. The numerical skills of children develop so early and

so inexorably that it is easy to imagine an internal clock of mathematical maturity guiding their growth. Not long after learning to walk and talk, they can set the table with impressive accuracy--one plate, one knife, one spoon, one fork, for each of the five chairs. Soon they are capable of noting that they have placed five knives, spoons, and forks on the table and, a bit later, that this amounts to fifteen pieces of silverware. Having thus mastered addition, they move on to subtraction. It seems almost reasonable to expect that if a child were secluded on a desert island at birth and retrieved seven years later, he or she could enter a second-grade mathematics class without any serius problems of intellectual adjustment.

Of course, the truth is not so simple. This century, the work of cognitive psychologists has illuminated the subtle forms of daily learning on which intellectual progress depends. Children were observed as they slowly grasped--or, as the case might be bumped into- concepts that adults take for granted, as they refused, for instance, to concede that quantity is unchanged as water pours from short stout glass into a tall thin one. Psychologists have since demonstrated that young children, asked to count the pencils in a pile, readily report the number of blue or red pencils, but must be coaxed into finding the total. Such studies have suggested that the rudiments of mathematics are mastered gradually, and with effort. They have also suggested that the very concept of abstract numbers--the idea of a oneness, a twoness, a threenes that applies to any class of objects and is a prerequisite for doing anything more mathematically demanding than setting a table--is itself far from innate.

What does the passage mainly discuss？

A．Trends in teaching mathematics to children.

B．The use of mathematics in child psychology.

C．The development of mathematical ability in children.

D．The fundamental concepts of mathematics that children must learn.

Teeth have been a part of animals almost from the beginning of animal life. The first

animals to have teeth were fish. These sea creatures lived millions of years ago. They had many finely pointed teeth for grabbing food from the water. They were distant cousins of today’s sharks.The teeth of animals help them do certain jobs or eat certain kinds of foods. Elephants have two large teeth, called tusks, which they use for digging up plants or for fighting. Lions and tigers have long, sharp teeth for tearing apart other animals. Those of horses and cows are short and flat. They are used for grinding plants.People have three main kinds of teeth. They have teeth that cut, teeth that tear, and teeth that grind. When biting into a piece of fruit, people use their cutting teeth. When pulling a piece of meat from a bone, they use their tearing teeth. When nibbling on a fresh carrot, they use their grinding teeth.Every person grows two sets of teeth. The first set often begins to appear when a baby is about six months old. It lasts until the child is about six years old. Then the baby teeth fall out and the second teeth come in. This second set must last for the rest of a person’s life.It is important for people to take care of their teeth. They must eat the right foods. They should brush their teeth properly.

第5题

Many visitors finds the fast pace at which American people move very troubling. One’s

first impression is likely to be that everyone is in a rush. City people always appear to be hurrying to get where they are going and are very impatient if they are delayed even for a brief moment. At first, this may seem unfriendly to you. Drivers will rush you; storekeepers will be in a hurry as they serve you; people will push past you as they walk along the street. You will miss smiles, brief conversations with people as you shop or dine away from home. Do not think that because Americans are in such a hurry they are unfriendly. Often, life is much slower outside the big cities, as is true in other countries as well. Americans who live in cities such as New York, Chicago, or Los Angeles, often think that everyone is equally in a hurry to get things done; they expect others to “push back”, just as city people do in Tokyo, Singapore or Paris, for example. But when they discover that you are a stranger, most Americans become quite kindly and will take great care to help you. Many of them first came to the city as strangers and they remember how frightening a new city can be .If you need help or want to ask a question, choose a friendly looking person and say, “I am a stranger here. Can you help me？” Most people will stop, smile at you, and help you find you way or answer your questions. But you must let them know that you need help. Otherwise they are likely to pass you by, not noticing that you are new to the city and in need of help. Occasionally, you may find someone too busy or perhaps too rushed to give you aid. If this happens, do not be discouraged; just ask someone else. Most Americans enjoy helping a stranger.

1.Many people who first visit the United States will find that _______.

A、 America is a highly developed country

B、 American city people seem to be always in a rush

C、 the fast pace in American life often causes much trouble

D、 Americans are impatient and unfriendly people

2.When the author says “You will miss smile”, he means ___________.

A、 you will fail to notice that Americans are pleasant and happy

B、 you will be puzzled why Americans do not smile at you

C、 you will feel that Americans do not seem very friendly

D、 you will find that Americans don't have much sense of humor

3.In the author’s opinion, ___________.

A、 it is true that life in New York is much faster than that in any other city

B、 people living outside big cities are lazy and miserable

C、 most American people enjoy living in the suburbs of big cities

D、 those who are busy are not necessarily unfriendly

4.The life pace in cities is much ___________ than the one outside cities.

A、 faster

B、 slower

C、 happier

D、 sadder

5.If you say to an American that you are a stranger there, most probably he will _________.

A、 offer his help

C、 help you find the way

D、 reply that he is pleased to meet you

The ideal companion machine — the computer — would not only look, feel, and sound friendly

but would also be programmed to behave in a pleasant manner. Those qualities that make interaction with other people enjoyable would be imitated as closely as possible, and the machine would appear to be charming, and easygoing. Its informal conversational style. would make interaction comfortable, and yet the machine would remain slightly unpredictable and therefore interesting. In its first encounter it might be somewhat hesitant, but as it came to know the user it would progress to a more relaxed and intonate style. The machine would not be a passive participant but would add its own suggestions, information, and opinions; it would sometimes take the initiative in developing or changing the topic and would have a personality of its own.

Friendships are not made in a day, and the computer would be more acceptable as a friend if it imitated the gradual changes that occur when one person is getting to know another. At an appropriate time it might also express the kind of affection that stimulates attachment and intimacy. The whole process would be accomplished in a subtle way to avoid giving an impression of over-familiarity that would be likely to produce irritation. After experiencing a wealth of powerful, well-timed friendship indicators, the user would be very likely to accept the computer as far more than a machine and might well come to regard it as a friend.

An artificial relationship of this type would provide many of the benefits that people obtain from interpersonal friendships. The machine would participate in interesting conversation that could continue from previous discussions. It would have a familiarity with the user's life as revealed in earlier contact, and it would be understanding and good-humored. The computer's own personality would be lively and impressive, and it would develop in response to that of the user. With features such as these, the machine might indeed become a very attractive social partner.

Which of the following is NOT a feature of the ideal companion machine？

A．Active in communication.

B．Attractive in personality.

C．Enjoyable in performance.

D．Unpredictable in behaviour.

第7题

Who talks more，women or men？ The seemingly conflicting evidence is resolved

by the difference between what I call public and private speaking.More men feel comfortable doing "public speaking," while more women feel comfortable doing "private" speaking.Another way of capturing these differences is by using the terms report-talk and rapport-talk.For most women, the language of conversation is primarily a language of rapport: a way of establishing connections and negotiating relationships. Emphasis is placed on displaying similarities and matching experiences. From childhood, girls criticize their friends who try to stand out or appear better than others. People feel their closest connections at home, or in places where they feel at home -- with one or a few people they feel close to and comfortable with -- in other words, during private speaking. But even the most public situations can be approached like private speaking.

For most women，talk is primarily a means to preserve independence and negotiate and maintain status in a hierarchical(等级制度的) social order.This is done by exhibiting knowledge and skill，and by ho1ding center stage through verbal performance such as torytelling，joking，or conveying information.From childhood，men learn to use talking as a way to get and keep attention.Therefore，they are more comfortable speaking in 1arger groups made up of people they know 1ess well，in the broadest sense，"public speaking”. But even the most private situations can be approached like public speaking,more like giving a report than establishing rapport.

21.A similar term for "private talking" is ___________.

[A]report-talk

[B]rapport-talk

[C]persuasive talk

[D]women's talk

22.When women talk，they tend to________.

[A]admire their friends who stand out

[B]make others feel at home

[C]approach public situations like private talking

[D]seek close relationship with other speakers

23. Men talk in order to________.

[A]make new friends

[B]share experience

[C]argue with others

[D]attract attention

24. The purpose of this passage is to _______.

[A]contrast the male and female talking styles

[B]prove that men talk more effectively than women

[C]analyze why men and women are different

[D]draw people's attention to the difference between men and women

25. Which of the following is true？

[A]Men talk more than women.

[B]Men feel more comfortable making a public speech than women.

[C]Men are more knowledgeable than women.

[D]Men are more independent than women.

A lot of kids are getting online these days —sharing data, talking about social issues, meeting adults as well as kids, and learning about other cultures.

A lot of kids are getting online these days—sharing data, talking about social issues, meeting adults as well as kids, and learning about other cultures. There seems to be everything on the network. Just like any other form. of media, the quality of this massive collection of information is

unequal, and there is good information as well as rubbish. Networks hold great promise: however,

it's also home to people who mean to hurt others or use their technical knowledge to steal from them . Although many Web pages can teach kids useful things, there are some other sites waiting to temp young people who are immature and easily affected.

By now, you may shake your head, but wait, let's try to put the problem into perspective Generally.it's safe for kids to use the Internet. The number of sites considered harmful is between 1% and 3%, which shows about 4.5 million other sites are interesting and educational. Besides, to stop children from using these services just because crimes are being committed online would be like telling them not to attend college because students may have accidents on campus.

What can parents do to protect their children from those harmful sites？ The simplest solution is the use of programs which block offensive sites. Such programs are set to screen out certain words likely to appear on”unhealthy”sites. But many sites inappropriate to young people are clever at using words with double meanings that may appear harmless. What's more, not only do the programs fail to do the job satisfactorily, they also take away the decisive role of parents in children's education. A child who downloads bad information or pictures can only be corrected by positive family influence. No filtering program is necessary for a child who has learned to say“no”to sites he knows are inappropriate for him.

Today, when children are exposed to technology at a young age, parents often find themselveslagging behindin computer skills. Surprisingly, this may be the key to your involvement. What is better way to learn about the Internet than to do so alongside your children？

They'll most likely pick it up more quickly than you do, of course, but you'll have the chance to see, and take pride in, your child at work. You may search for information that interests your child together with him and get to know the”friends”he has online, just as you would get to know his other friends.

Thoughtful parents would combine supervision with communication, which is the best way to take advantage of the Internet as a resource while protecting their children. Follow their examples and have fun with kids on the Net!

51. According to the passage, is it wise for parents to keep their children away from the computer？Why？

A) No. Because there are also millions of sites which are interesting and educational.

B) No. Because their children have the right to use computer,

C) Yes. Because there are many rubbish sites which may hurt children.

D)Yes. Because children may become addicted to computer games.

52. In the last two paragraphs, parents are advised to ()

A) learn about the Internet along with their children

B) watch their children while they are at work

C) search for information for their children

D) make friends with their children

53. According to the article, the best way to protect children as well as take advantage of the Internet is ().

A) the use of filtering programs

B) parents，mastery of computer skills

C) the combination of supervision and communication

D) forbidding them to make friends on the Internet

Michael, a typical American, stays at home on workdays. He plugs into his personal com

puter terminal in order to connect with the office. After work, he puts on his headphones, watches a movie on his home video recorder, or plays baseball on the computer. On many days, Michael doesn’t talk to any other human beings, and he doesn’t see any people except the ones on television. Michael is imaginary, but his lifestyle. is very possible. The inventions of modern technology seem to be cutting us off form. contact with our fellow human being. The world of business is one area in which technology is isolating us. Experts say, for example, that many people will soon be able to work at home. With access to a large central computer, employees such as office clerks, insurance agents, and accountants could do their jobs at display terminals in their own homes. They would never have to actually see the people they’re dealing with. In addition, the way employees are paid will change. Workers’ salaries will be automatically paid into their bank accounts, making paper checks unnecessary. No workers will stand in line to receive their pay or cash their checks. Personal banking will change, too. Customers will deal with machines to put in or take our money from their accounts. Another area that technology is changing is entertainment. Music, for instance, was once a group experience. People listened to music at concert halls or in small social gatherings. For many people now, however, music is an individual experience. Walking along the street or sitting in their living rooms, they wear headphones to build a wall of music around them. Movie entertainment is changing, too. Movies used to be social events. Now, fewer people are going out to see a movie. Many more are choosing to wait for a film to appear on television or are borrowing videotapes to watch at home. Instead of laughing with others, viewers watch movies in their own living rooms.

第10题

The purpose of the American court system is to protect the rights of the people. According

to American law, if someone is accused of a crime, he or she is considered innocent until the court proves that the person is guilty. In other words, it is the responsibility of the court to prove that a person is guilty. It is not the responsibility of the person to prove that he or she is innocent.

In order to arrest a person, the police have to be reasonably sure that a crime has been committed. The police must give the suspect the reasons why they are arresting him and tell him his rights under the law. Then the police take the suspect to the police station to "book" him. "Booking" means that the name of the person and the charges against him are formally listed at the police station.

The next step is for the suspect to go before a judge. The judge decides whether the suspect should be kept in jail or released. If the suspect has no previous criminal record and the judge feels that he will return to court rather than run away — for example, because he owns a house and has a family — he can go free. Otherwise, the suspect must put up bail. At this time, too, the judge will appoint a court layer to defend the suspect if he can't afford one.

The suspect returns to court a week or two later. A lawyer from the district attorney's office presents a case against the suspect. This is called a hearing. The attorney may present evidence as well as witnesses. The judge at the hearing then decides whether there is enough reason to hold a trial. If the judge decides that there is sufficient evidence to call for a trial, he or she sets a date for the suspect to appear in court to formally plead guilty or not guilty.

At the trial, a jury of 12 people listens to the evidence from both attorneys and hears the testimony of the witnesses. Then the jury goes into a private room to consider the evidence and decide whether the defendant is guilty of the crime. If the jury decides that the defendant is innocent, he goes free. However, if he is convicted, the judge sets a dale for the defendant to appear in court again for sentencing. At this time, the judge tells the convicted person what his punishment will be. The judge may sentence him to prison, order him to pay a fine, or place him on probation.

The American justice system is very complex and sometimes operates slowly. However, every step is designed to protect the rights of the people. These individual rights are the basis, or foundation, of the American government.

What is the main idea of the passage？

A．The American court system requires that a suspect prove that he or she is innocent.

B．The US court system is designed to protect the rights of the people.

C．Under the American court system, judge decides if a suspect is innocent or guilty.

D．The US court system is designed to help the police present a case against the suspect.

第11题

The inner voice of people who appear unconscious can now be heard. For the first time, res

earchers have struck up a conversation with a man diagnosed as being in a vegetative (植物的) state. All they had to do was monitor how his brain responded to specific questions.

"They can now have some involvement in their destiny," says Adrian Owen of the University of Cambridge, who led the team doing the work.

In an earlier experiment, Owen's team asked a woman previously diagnosed as being in a vegetative state to picture herself carrying out one of two different activities. The resulting brain activity suggested she understood the commands and was therefore conscious.

Now Owen's team has taken the idea a step further. A man also diagnosed with VS was able to answer yes and no to specific questions by imagining himself engaging in the same activities.

The results suggest that it is possible to give a degree of choice to some people who have no other way of communicating with the outside world. "We are not just showing they are conscious, we are giving them a voice and a way to communicate," says neurologist (神经病学家) Steven Laureys of the University of Liege in Belgium, Owen's partner.

Doctors traditionally base these diagnoses on how someone behaves: for example, whether they can glance in different directions in response to questions. The new results show that you don't need behavioural indications to identify awareness and even a degree of cognitive proficiency. All you need to do is tap into brain activity directly.

The work "changes everything", says Nicholas Schiff, a neurologist at Weill Cornell Medical College in New York, who is carrying out similar work on patients with consciousness disorders. "Knowing that someone could persist in a state like this and not show evidence of the fact that they can answer yes/no questions should he extremely disturbing to our practice."

One of the most difficult questions you might want to ask someone is whether they want to carry on living. But as Owen and Laureys point out, the scientific, legal and ethical challenges for doctors asking such questions are formidable.

"They" in the second paragraph can be replaced by "______".

A．patients in a VS

B．researchers

C．monitoring machines

D．specific questions
