2. 青少年上网成瘾的主要原因是…；

3. 对此问题的解决办法

学生回答:

Internet addiction among young people has long been recognized as a social problem in China. It's a common known fact that Internet addiction can have a devastating effect on young peoples' health and social lives. Students may waste too much of their youth in front of a computer screen. Many youth are the only child in their families. They don't have enough chance to associate with parents. Also, the lack of activities for them can lead to internet addiction. When people grow up, if they don't spend time on sports or other positive interests they often turn to the Internet to kill time. How do we deal with this problem? Associating more with family, friends and nature can really help internet addicts kick the habit. Everyone understands that parents nowadays are busy, but if they just spend more time communicating with their kids, they can help avoid their children from becoming addicted to the internet. But more than this, all of society should become concerned about the negative sides of the Internet. Thoroughly eradicating the problem of internet addiction involves many branches of society. We need more positive cultural products, we need to communicate with others more in the real world, and we also need to think about balancing economic prosperity with the futures of our kids.

She Wanted to Teach

A railroad was being built all the way down the east coast off Florida, from Jacksonville to Miami and Negro workers were employed because they were cheap. A great many of them were in Daytona. Most of them had children. They were living in shacks worse than those in the Terry in Augusta. The children were running wild in the streets. Mary Bethune seemed to hear a voice say, “What is the place? Build your school there.”

Her husband, Albertus, wasn’t so sure about her school. He thought Palatka was a pretty good place for them to live. Mary listened but she never gave up her idea. She knew that if she went to Daytona, Albertus would come too.

One day she begged a ride for herself and her little boy with a family that was going to Daytona. It was only seventy miles away. But in 1904 the sand was deep on Florida roads.

Practically no one had an automobile — certainly not the poor family that gave Mary and little Albert a ride. So it was three dusty days after they left Palatka before they reached Daytona. There Mary hunted up the only person she knew, and she and little Albert stayed with this friend for a few days.

As she had done in The Terry in Augusta, Mary walked up and down the poor streets of Daytona. She was looking for two things — a building for the school she was determined to start and some pupils for that school.

After a day or two, she found an empty shack on Oak Street. She thought this would do. The owner said she could rent it for $11.00 a month. But it wasn’t worth that much. The paint had peeled off, the front steps wobbled (摇晃) so that she had to hang onto the shaky railing to keep from falling, the house was dirty, it had a leaky roof. In most of the windows the panes of glass were broken or cracked.

Eleven dollars a month! Mary said she only had $1.50. She promised to pay the rent as soon as she could earn the money. The owner trusted her. By the time she was sure she could have the building, she had five little girls from the neighborhood as her pupils.

What a school! A rickety old house and five little girls! The little girls pitched in and cleaned the house. The neighbors helped with scrubbing brushes, brooms, hammers, nails, and saws. Soon the cottage could be lived in, but there were no chairs, no tables, no beds. There was no stove. However, there were no pots and pans to cook in, even if there had been a stove. Mary set about changing these things. She found things in trash piles and the city dump. Nobody but Mary would have thought of making tables and chairs and desks from the old crates she picked up and brought home. Behind the hotels on the beach she found cracked dishes, old lamps, even some old clothes. She took them home too. Everything was scoured and mended and used. “Keep things clean and neat” was her motto then; and as long as she lived the pupils in her school had to live up to that motto.

Her little pupils had no pencils. They wrote with pieces of charcoal made from burned logs. Their ink was elderberry juice. What good was ink or a pencil if there was no paper to write on? Mary took care of that too.

Every time she went to the store to get a little food, or a few pots and pans, she had each article wrapped separately. The pieces of wrapping paper were carefully removed and smoothed out. The little girls used this paper to write their lessons with their charcoal pencils. She needed a cookstove very badly but she couldn’t pay for one. What should she do? Her little pupils had to have warm food.

Unexpectedly, the problem was solved for her. One day a wrinkled old white neighbor said to her, “Can you read?”

Mary said, “Yes.”

“Then will you read me this letter from my son? I can’t find my glasses”

Mary read the letter to her.

“Thanks,” said the mother.

Mary turned to go. “You’re welcome.”

The old woman stood by her open door and thought a moment. Then she said, “I got an old cookstove and I don’t need it. Would you want it?”

Statements

1. According to the passage, we know that a railroad was under construction and

it would connect Jacksonville with Miami.

2. The children of the Negro workers couldn’t attend school because Negroes had low social status.

3. Mary’s husband, Albertus, was in favor of her idea of going to Daytona.

4. Mary and little Albert took a car and reached Daytona three days after they left Palatka.

5. Mary was making preparations for her school.

6. The empty shack on Oak Street was in poor condition.

7. We can infer that Mary succeeded in renting the shack from the owner and she enrolled five girl students.

8. Mary couldn’t find a solution to furnish her school with t ables, chairs and desks.

9. Mary’s pupils used elderberry juice to write with because they preferred it to ink.

10. An old woman offered an old cookstove to Mary and Mary solved her problem unexpectedly.

答案:

Physical Exercise

More and more people today are realizing the importance of physical exercise. Because of better working conditions, nowadays people don’t need to do hard jobs and their daily lives do not provide them with the exercise their body need. In order to keep them healthy and make their body strong, they must spend part of their free time doing physical exercise.

There are many different forms of physical exercise to suit different tastes. Some people enjoy playing tennis or badminton or swimming. Others prefer to go running or jogging regularly in the morning and evening. Most elderly people go in for the traditional forms of exercise; you can see them learning and practicing qigong or taijiquan. The traditional forms of exercise suit them best.

As a college student I also persist in doing physical exercise so as to keep healthy and concentrate my energies on my study. Every morning I do morning exercise and run around the playground. After class in the afternoon, I play basketball and table tennis. Besides, I have physical education courses every week.

Best of friends, Worlds Apart

Havana, sometime before 1994: As dusk descends on the quaint seaside village of Guanabo, two young men kick a soccer ball back and forth and back and forth across the sand. The tall one, Joel Ruiz, is black. The short, muscular one, Achmed Valdes, is white.

They are the best of friends.

Miami, January 2000: Mr. Valdes is playing soccer, as he does every Saturday, with a group of light-skinned Lationos in a park near his apartment. Mr. Ruiz surprises him with a visit, and Mr. Valdes, flushed and sweating, runs to greet him. They shake hands warmly.

But when Mr. Valdes darts back to the game, Mr. Ruiz stands off to the side, arms crossed, looking on as his childhood friend plays the game that was once their shared joy. Mr. Ruiz no longer plays soccer. He prefers basketball with black Latinos and African-Americans from his neighborhood.

The two men live only four miles apart, not even 15 minutes by car. Yet they are separated by a far greater distance, one they say they never imagined back in Cuba.

In ways that are obvious to the black man but far less so to the white one, they have grown apart in the United States because of race. For the first time, they inhabit a place where the color of their skin defines the outlines of their lives －where they live, the friends they make, how they speak, what they wear, even what they eat.

“It’s like I am here and he is over there,” Mr. Ruiz said, “And we can’t cross over to the other’s world.”

It is not that, growing up in Cuba’s mix of black and white, they were unaware of their difference in color. Fidel Castro may have officially put an end to racism in Cuba, but that does not mean racism has simply gone away. Still, color was not what defined them. Nationality, they had been taught, meant far more than race. They felt, above all, Cuban.

Here in America, Mr. Ruiz still feels Cuban. But above all he feels black. His world is a black world, and to live there is to be constantly conscious of race. He works in a black-owned bar, dates black women, goes to an African-American barber. “White barbers”, he say, “don’t understand black hair.” He generally avoids white neighborhoods, and when his world and the white world meet, he feels always watched, and he is always watchful.

For Joel Ruiz, there is little time for relaxation. On this night, he works as a cashier at his uncle’s bar in a black Miami neighborhood.

Mr. Valdes, who is 29, a year younger than his childhood friend, is simply, comfortably Cuban, an upwardly mobile citizen of the Miami mainstream. He lives in an all-white neighborhood, hangs out with white Cuban friends and goes to black neighborhoods only when his job, as a deliveryman for Restonic mattresses, forces him to. When he thinks about race, which is not very often, it is in terms learned from other white Cubans: American blacks, he now believes, are to be avoided because they are dangerous and resentful of whites. The only blacks he

trusts, he says, are those he knows from Cuba.

Since leaving Havana in separate boats in 1994, the two friends have seen each other just a handful of times in Miami －at a funeral, a baby shower, a birthday party and that soccer game, a meeting arranged for a newspaper photographer. They have visited each other’s homes only once.

They say they remain as good friends as ever, yet they both know there is little that binds them anymore but their memories. Had they not become best friends in another country, in another time, they would not be friends at all today.

Statements

1. Mr. Ruiz and Mr. Valdes are both Cuban- Americans.

2. Mr. Ruiz and Mr. Valdes feel separated from each other in the United States because they don’t live in the same neighborhood.

3. In the United States, the color of one’s skin will influence the way they travel

4. In Cuba, people feel that compared to nationality, the color of one’s sk in is unimportant.

5. Mr. Valdes thinks white barbers don’t understand black hair.

6. Living in a white neighborhood, Mr. Valdes seems to be unconscious of racial issues.

7. Mr. Ruiz lives in an apartment in a black neighborhood.

8. It can be inferred from the passage that Mr. Valdes can still move up the social ladder.

9. Both Mr. Ruiz and Mr. Valdes left Cuba in 1994.

10. All that Mr. Ruiz and Mr. Valdes have left of their friendship are their memories.

3.我的观点。

学生回答:

答案:

On Optional Courses

The discussion about optional courses has never stopped in the past few years. Its advantages and disadvantages are evident. The biggest advantage of optional courses is its variety. Students can choose any course in which th ey have a special interest. What’s more, optional courses often bring creative research findings or up-to-date breakthroughs, which are hardly seen in normal courses.

However, the negative effects are also obvious. To begin with, some students choose optional courses only to earn some credits or obtain a certificate --- they never put their hearts into studying the subject. In the second place, optional courses take up too much time and it is difficult for students to make the best of both worlds.

Up till now, we can see it clearly that an optional course is not beneficial or harmful in itself. In my opinion, the key lies in the user --- so long as we can make use of it properly, it can be most helpful for us in many respects.

Black Holes

It was a star vastly larger than our own sun. For hundreds of years this giant star burned brightly in its corner of the universe. Then, at the end of its life span, a strange thing happened. The dying star began to collapse in on itself. While the star was in its death throes, all the matter that made up the star was squeezed together into a smaller and smaller area. Soon the star measured no more than a mile across. Its matter was so tightly packed that a piece of it the size of a small stone weighed as much as a mountain.

As the dead star continued to fall into itself, it brought with it every bit of matter in the area. Every speck of dust, every stray atom, was dragged into it. The star had

become a black hole. A black hole is a small area of matter so dense that not even a light beam can escape the pull of its gravity.

Since no light can leave black holes, there is no way for us to see them. They are invisible. We know of their existence because of the strange things that happen around them. Light that is traveling through space just vanishes.

Just how wild is a black hole? Let’s take a look at gravity. A common expression related to gravity is, “What goes up must come down.” When someone throws a ball into the air, it must return to Earth. This happens because Earth attracts the ball, or pulls it toward itself. A flowerpot that is knocked off a third-story window will always hit the sidewalk. It is only the great thrust of giant rockets that allows the space shuttle to escape the pull of earth’s gravity On a planet with double or triple Earth’s gravity, objects would act quite differently, beca use the pull, or attraction, would be much stronger. A ball thrown into the air would not go very high, and it would plunge quickly back to the surface of the planet. A falling flowerpot would be a deadly weapon. It would kill any luckless pedestrian who might happen to get hit by it. Rockets far more powerful than those used on Earth would be needed to break away from the pull of the planet’s gravity.

Beams of light, however, would have no trouble at all escaping from this planet. Even if the force of gravity were increased to a million times that of Earth, light beams would still not be affected. Humans on such a world would be crushed flatter than their own shadows.

Only if the amount of gravity were many millions of times stronger than Earth’s would light beams bent back to the surface. That is the case with a black hole. It is hard to imagine just how dense and heavy black hole matter is. A penny made from black hole matter would rip through your pocket and plunge through the earth with the greatest of ease. When it emerged on the other side, it would hover in the air for a moment and then plunge back through the earth.

Black holes are the strangest objects in the universe. Nothing ever leaves a black hole. No light leaves it. No physical objects leave it. Once some thing enters a black hole, it is there forever. Black holes are like permanent detention halls in the sky. If a travel agent were to arrange a flight to a black hole, it would have to be a one-way trip. As the scientist Robert Jastrow sai d, “It is almost as though the material inside the black hole no longer belongs to our universe.

Suppose, just for the sake of amusement, that you happened to drop into a black hole. What would happen to you? Think of going feet first. Your feet would be pulled down faster than your ears. As a result, you would be drawn into a very thin thread of matter. Then the

individual atoms of your body would be pulled apart.

Were you to survive the trip, however, some scientists believe that you would emerge in the fourth dimension. You would be in a totally different universe. The point where matter exists from this universe and goes into the next is referred to as a white hole. But, then, no one really knows for sure. Our knowledge of black holes is based only on informed guesswork. Statements

1. The giant star collapsed into several smaller stars at the end of its life span.

2. A black hole is a small piece of matter whose gravity is a million times that of the earth.

3. A black hole results from the death of a giant star.

4. Black holes are too far away to be seen by telescope.

5. Since objects would act quite differently on a planetwith double or triple Earth’s gravity, people can not live on it.

6. Light is the last thing affected by the black hole.

7. A penny made from black hole matter would plunge through the earth again and again and never stop.

8. One day, travel agent would be able to arrange trips to black holes.

9. A white hole is at the bottom of a black hole.

10. Black holes are strange, extremely dense objects whose existence scientists can only guess about.

学生回答:

答案:

How to Conduct Patriotic Education among the Youth of Today

Much to our distress, these years have seen a widespread neglect of patriotic education in our society. Many patriotic education centers have been closed down or kept open to the public for other more profitable purposes while many of our national heroes have given way to today’s pop stars in youths’ minds. If allowed to run its course, this current is bound to turn for the worse, with less and less sense of patriotism left in the youth.

The significance of patriotic education to our society, however, can be seen from the perspectives as follows. In the first place, the patriotic education can make youth more aware of the glorious history and culture of our nation, thus building up their sense of pride as Chinese. In the second, the patriotic education helps youth value today’s hard-earned life so as to hold dearer their golden chances of enriching themselves with knowledge in peace. And above all, the patriotic education can push youth to draw upon more of their capabilities in order to make tomorrow’s life better than today’s and leave behind themselves more highlights for the nation’s culture.

So the most pressing for us now is how to effectively inculcate patriotism in the youth of today. In my opinion, the first step should be focused upon giving fuller play to the potentials of patriotic education centers instead of running them for the purpose of making money. Then, greater efforts must be made to integrate the patriotic education into the curriculums throughout youth’s education. In one word, where there is an effective patriotic education of youth, there is a greater enhancement of national cohesiveness.

NNCE Book3课后翻译参考答案 Unit1 英译中原文：Global citizen is someone who identifies with being part of an emerging world community and whose actions contribute to building this community's values and practices. Global citizenship believes that humankind is essentially on and each individual has the power to change things.In our interdependent world, global citizenship encourages usto recognize our responsibilities toward each other and learn from each other. Global citizens care about education, disease, poverty, and environmental issues around the world. Today, the forces of global engagement are helping some people identify themselves as global citizens who have a sense of belonging to a world community. This growing global identity in large part is made possible by the forces of modern information, communications and transportation technologies. Global citizenship aims to empower people to lead their own action. Along with the knowledge and values that they have gained from learning about global issues, people need to be equipped with the necessary skills to give themselves the ability and confidence to be pro-active in making a positive difference in the world. Keys：世界公民是指一个人承认自己是新兴的全球社区的一分子，而且其行动对全球社区的价值打造和实践活动有所贡献。世界公民相信人类从本质上来说是一个整体，任何个人都有改变事物的能力。在我们这样一个相互依赖的世界中，世界公民意识鼓励我们认识到对彼此的责任，并从对方身上学习。世界公民关心全球的教育、疾病、贫穷和环境问题。在当今，全球合作的力量在使一些人萌发世界公民的意识，让他们拥有对全球社区的归属感。这种不断发展的世界公民意识在很大程度上来讲，要归功于现代信息、通信和交通技术的力量世界公民意识致力于给予人们力量，让他们付诸行动，世界公民除了要从世界问题中学习知识和价值观，还要拥有必需的技能，使他们拥有能力和自信，积极推动世界的发展。汉译英原文：如今，很多年轻人不再选择" 稳定" 的工作，他们更愿意自主创业，依靠自己的智慧和奋斗去实现自我价值。青年创业（young entrepreneurship）是未来国家经济活力的来源，创业者的成功不但会创造财富、增加就业机会、改善大家的生活，从长远来看，对于国家更是一件好事，创业者正是让中国经济升级换代的力量。尤其是在当前，国家鼓励大众创业、万众创新，在政策上给予中小企业支持，这更加激发了年轻人的创业热情。 Keys：Nowadays, many young people no longer choose "stable" jobs. Instead, they prefer to start their own businesses and realize their self-value through their own wisdom and efforts. Young entrepreneurship is the source of national economic vitality in the future. The success of entrepreneurs not only creates fortune, increases job opportunities, improves people's life, but it is also good for the country in the long term. Entrepreneurs are a driving force in upgrading China's economy. Especially for the time being, our country is encouraging people to start their own businesses and make innovations and giving policy support for medium and small businesses.

Never, ever give up! 1 As a young boy, Britain's great Prime Minister, Sir Winston Churchill, attended a public school called Harrow. He was not a good student, and had he not been from a famous family, he probably would have been removed from the school for deviating from the rules. Thankfully, he did finish at Harrow and his errors there did not preclude him from going on to the university. He eventually had a premier army career whereby he was later elected prime minister. He achieved fame for his wit, wisdom, civic duty, and abundant courage in his refusal to surrender during the miserable dark days of World War II. His amazing determination helped motivate his entire nation and was an inspiration worldwide. 英国首相温斯顿·丘吉尔小时候就读于一所名为哈罗的公立学校。他不是一个好学生，如果他不是来自一个有名的家庭，他可能会因为背离校规而被开除出学校。谢天谢地，他在哈罗大学毕业了，他的错误并没有妨碍他继续上大学。他最终有了一个陆军总理的职业生涯，后来他被选为首相。他以机智、智慧、公民责任和在二战黑暗的日子里拒绝投降的勇气而出名。他惊人的决心有助于激励他的整个国家，也是全世界的灵感来源。 2 Toward the end of his period as prime minister, he was invited to address the patriotic young boys at his old school, Harrow. The headmaster said, "Young gentlemen, the greatest speaker of our time, will be here in a few days to address you, and you should obey whatever sound advice he may give you." The great day arrived. Sir Winston stood up, all five feet, five inches and 107 kilos of him, and gave this short, clear-cut speech: "Young men, never give up. Never give up! Never give up! Never, never, never, never!" 在他担任总理的时期即将结束之际，他被邀请在他的旧学校哈罗向爱国青年发表演讲。校长说：“年轻的先生们，我们这个时代最伟大的演讲者，几天后将到这里向你们讲话，你们应该听从他给你们的任何合理建议。”伟大的一天到来了。温斯顿爵士站了起来，他身高五英尺五英寸，体重107公斤，简短而清晰地说：“年轻人，永不放弃。永不放弃！永不放弃！从不，从不，从不，从不！” 3 Personal history, educational opportunity, individual dilemmas —none of these can inhibit a strong spirit committed to success. No task is too hard. No amount of preparation is too long or too difficult. Take the example of two of the most scholarly scientists of our age, Albert Einstein and Thomas Edison. Both faced immense obstacles and extreme criticism. Both were called "slow to learn" and written off as idiots by their teachers. Thomas Edison ran away from school because his teacher whipped him repeatedly for asking too many questions. Einstein didn't speak fluently until he was almost nine years old and was such a poor student that some thought he was unable to learn. Yet both boys' parents believed in them. They worked intensely each day with their sons, and the boys learned to never bypass the long hours of hard work that they needed to succeed. In the end, both Einstein and Edison overcame their childhood persecution and went on to achieve magnificent discoveries that benefit the entire world today. 个人历史、教育机会、个人困境——这些都不能抑制致力于成功的坚强精神。没有任务太难。准备的时间不要太长或太难。以我们这个时代最有学术价值的两位科学家为例，阿尔伯特·爱因斯坦和托马斯·爱迪生。双方都面临巨大的障碍和极端的批评。两人都被老师称为“学习慢”，并被他们的老师当作白痴注销。托马斯·爱迪生逃学是因为他的老师因为问太多问题而不断鞭打他。爱因斯坦直到九岁时才说得流利，他是一个很穷的学生，有些人认为他无法学习。然而，两个男孩的父母都相信他们。他们每天都和儿子们一起努力工作，孩子们学会了永远不要绕开他们要成功所需的长时间辛勤工作。最后，爱因斯坦和爱迪生都克服了童年时代的迫害，继续取得了有利于当今世界的伟大发现。
