Because we can feel that things are very heavy, we think of weight as being a fixed quality, but it is not really fixed at all. If you could take a one-pound packet of butter 4 000 miles out from the earth, it would weigh only a quarter of a pound.

Why would things weigh only a quarter as much as they do at the surface of the earth if we took them 4 000 miles out into space? The reason is this: all objects have a natural gravity(引力)for all other objects; this is called gravitational attraction(万有引力). But this power of attraction between two objects gets weaker as they are farther apart. When the butter was at the surface of the earth, it was 4 000 miles from the center. When we took the butter 4 000 miles out, it was 8 000 miles from the center, which is twice the distance.

If you double the distance between two objects, their gravitational attraction decreases two times two. If you make the distance three times far away, it gets nine times weaker (three times three). If you make it four times far away, it gets sixteen times weaker (four times four) and so on.

So this is one of the first things we need to remember: the weight of an object in space is not the same as its weight on the surface of the earth.

1.Which of the following is right?

A.A thing has the same weight everywhere in space.

B.Weight is a fixed quality in an object.

D.A thing’s weight changes with its place in space.

2.There is      between     .

A. gravity; objects?                      B.power; all objects

C.gravity; the two objects only?            D.power; two things

3.A 400 pound man-made satellite is sent to the place 2 000 miles out from the earth. Its weight is about     .

A.200 pounds                          B.a half pounds

C.100 pounds                          D.300 pounds

4.If we make the distance between objects five times as far away,     .

A. it gets twenty-five times weaker

B.their weight gets twenty-five times weaker

C.their gravity gets twenty-five times weaker

D.their gravity gets twenty-five times stronger

5.After reading this passage, we should remember that we know the usual weight of a thing     .

A. because it is on the surface of the earth

B.because it is weighed

C.because it is in space

D.because it is not far away from the earth

 

David, a French priest (牧师)of thirty-six, was sent to China by the church in 1872. He did well in the natural and social science besides his religious activities (宗教活动). He was also very interested in the rare wild animals and plants in China.

On May 4th ,1879, after searching for half a month in the western part of Baoxing, Sichuan the hunters hired (雇用) by David succeeded in bringing him a “black-and-white bear”. “The bear is extremely lovely”, he wrote in his diary excitedly. Meanwhile, he felt it might be a new species (物种)never discovered by scientists.

He then decided to send it to Paris for a further study. Unfortunately the poor “black-and white” bear died of Jolts (颠簸) of the mountain roads and the climatic (气候) change. He had to send its pelt (皮毛)to the National Museum in Paris for display (展览). In fact, the so-called “black-and white” bear was neither a bear nor a cat. After a complete study, Milla Edwards, head of the museum, judged that it was a new species. He gave the “giant panda”.

The discovery made the world excited and Baoxing was also made famous for “home of the giant panda”

The cost of medical care in the United States is very high. The time and money that doctors spend on their medical education is probably one reason for this problem.

A visit to a doctor’s office costs from fifteen to fifty dollars. It is almost impossible for people to pay for medical care they need. Many people in the United States think that doctors are overpaid. Most doctors, however, disagree. They say that they were required to study medicine for a long time. Tuition(学费)for many years of medical education costs lots of money. Doctors say that it is necessary for most medical students to borrow money from a bank to pay their tuition. Because this money must be repaid to the bank, young doctors need to receive a lot of money for their work. So they charge(收费)people high prices for medical care.

Therefore, it’s possible that the high cost of medical care in America is unnecessary. Because high tuition is one cause of high costs, one way to lower costs would be to have medical schools that are free or have lower tuition.

Today many people say that women have the same chance as men in society. But this was not always so. In the past, women all over the world had to fight to get the same chance as men in education and jobs. Many people said that women should not receive much education because they would not do as well as men when they went to work..

One woman who showed that women should have the same chance was Marie, a scientist.

In the 1800s scientists knew that a metal, uranium, gave off radiation. They also knew how much radiation came from this element. But they didn’t know what this radiation was like; they wondered why and how uranium gave off radiation. Marie Curie set out to answer these questions. In one of her experiments she was studying a certain material which, she knew, contained uranium, but it gave off 4 times as much radiation as it usually does. What could explain this fact? Marie Curie thought that there must be another source of radiation in this material.

In 1898 Marie Curie set out to find out this new source of radiation, which she named “radium”. Her husband, who was also a scientist, helped her. They set up a laboratory in an old building behind a school. For four years Curies searched, doing many experiments, and one morning in 1902 Marie found the source of the radiation.

Marie Curie proved to the world that there was element that gave off radiation. And she also proved to the world that, if women are given truly equal chance, they can really help society.

Most of us trade money for entertainment. Movies, concerts and shows are enjoyable but expensive. If you think that you can’t have a good time without spending a lot of money, read on. A little resourcefulness and a few minutes of news-paper-scanning should give you some pleasant surprises. People may be the most interesting show in a large city. Stroll through busy streets and see what everyone else is doing. You will probably see what everyone else is doing. You will probably see people from all over the world; you will certainly see people of every age, size, and shape, and you will get a free fashion show, too. Window-shopping is also a safe sportif the stores are closed.

Check the listings in your neighborhood paper. Local colleges or schools often welcome the public to hear an interesting speaker or a good debate. The film or concert series at the local public library probably won’t cost you a penny. By sure to check commercial advertisements too. A flea market can provide hours of pleasant browsing. Perhaps you can find a free cooking or crafts demonstration in a department store.

Plan ahead for some activities. It is always more pleasant not to have people in front of you in a museum or at a zoo. You may have saved some money too, since these places often set aside one or two free admission days at slow times during the week. Pretend that you are a tourist from time to time, and get to know your city all over again including the indispensable sights that people travel miles to see. If you feel like taking an interesting walk, find a free walking tour, or plan one yourself. You will see your city in a new perspective once you know about its history or its architectural treasures. With imagination and a spirit of adventure you can quite easily find good entertainment at no cost at all.

In the United States 84 colleges now accept just women. Most of them were established in the 19th century; they were designed to offer women the education they could not receive anywhere else. At that time major universities and colleges accepted only men. In the past 20 year many young women have chosen to study at colleges that accept both men and women. As a result some women’s colleges decided to accept men students too. Other, however, refused to change. Now these schools are popular again.

  The president of Trinity College in Washington, D.C. said that by the end of the 1980s women began to recognize that studying at the same school with men did not mean women were having an equal chance to learn. The president of Smith College in Massachusetts says a women’s college permits women to choose classes and activities freely. For example, she says that in a women’s college a higher percentage of students study mathematics than in a college with both men and women.

  Educational experts say men students in the United States usually speak in class more than women students do. In a women’s college, women feel free to say what they think. Women’s schools also bring out leadership capabilities in many women. Women are represented everywhere. For example, at a women’s college every governing office is held by a woman. Recent studies reportedly show this leadership continues after college. The studies show that American women who went to women’s colleges are more likely to hold successful jobs later in life.

The Internet is a system of electronic communication. It helps people share information, communicate with family and friends, and start businesses. But these people must have to use for a computer, and know how to use it. And they must have a connection. All of this costs money. For many poor people, a so-called “digital divide” exists. People who cannot connect to the Internet become poorer, while those who can become richer.

  The United Nations is working to solve this problem. In December, it will hold a conference in Geneva, called the World Summit(峰会)on the Information Society. Political and business leaders will come together with delegates(代表)from nongovernmental organizations, educational groups and others. They will discuss the fast growing information technology industry and its effects on the world.

  UN organizers say they hope the gathering will lead to a political declaration and action plan. The goal is to bridge the digital divide between rich and poor nations. A second conference, to examine progress, will take place in Tunisia in 2005.

  UN Secretary General Kofi Annan recently spoke to business leaders at a meeting in New York. Mister Annan urged them to take part in the World Summit on the Information Society. He told them that industry can play an important part in limiting technological differences between countries. He noted that some companies already made efforts to improve Internet skills among poor Americans. The UN Secretary General urged businesses to also look for projects in developing countries.

  Cisco Systems in San Jose, California, is one company that already does that. In 1997, Cisco began a special program to teach Internet technology skills to people around the world. Today, the Cisco Networking Academy (学院)has spread to 145 nations.

  Mister Annan says more ideas like this are needed to close the digital divide. He says information technology is not a magic(有魔力的) answer for poor nations, but it can lead to peace and development. He says news and information provided through the Internet help build trade, employment, good government and democracy around the world.

Children love to send and receive e-mails. The same with electronic greeting cards, for Valentine’s Day or many other occasions.

E-cards are available for free on the Internet. Most electronic greeting card sites give you a wide selection of choices and let you personalize your card.

Unlike with traditional printed cards, you don’t schlep(拖曳) to a card store to make your selection, you don’t fork out any money. Delivery is immediate; there’s no postage required and you are not using paper.

But the best thing about these card sites is that they animate and play music, which makes them very cool to kids.

Most electronic greeting card sites are similar in set-up. Upon entering the site, you select a category of card that interests you. The next screen shows you a series of possible card choices. By clicking on one that appeals(有感染力) to you, the card will enlarge and may animate. If there is music with the card, it will start to play.

Usually there is a place to click to see the second (inside) page of the card. The site then offers you ability to personalize the card you have selected; you may be able to change the proposal message or add to it. At some sites, you can even add voice, video or photos to the cards.

Once you have personalized the e-card, you enter the e-mail address for delivery. Your recipient(接受者)will get an e-mail telling them to go to a specific web address to view the card you have made. You may be able to send the same card to multiple recipients. The delivery can be immediate, or you can choose to have it delivered on a specific day.

Most electronic greeting card sites, like many other fields, have lots of advertising. Many make their money by enticing(诱惑) people to buy extra stuff like gift certificates to add to navigate through this commercialism(利润第一主义)and to hand in areas that are fun and appropriate for them.

Without most people realizing it, there has been revolution in office work over the last ten years. Before that time, large computers were only used by large rich companies that could afford the investment. With the advancement of technology, small computers have come onto the market which are capable of doing the work which used to be done by much larger and expensive computers, so now most smaller companies can use them.

The main development in small computers has been in the field of word processors, or WPS as they are often called.40% of British offices are now estimated to have a word processor and this percentage is growing fast.

There are many advantages in using a word processor for both secretary and manager. The secretary is freed from a lot of daily work, such as re-typing letters and storing papers. He or she can use this time to do other more interesting work for the boss. From a manager’s point of view, secretarial time is being made better use of and money can be saved by doing daily jobs automatically outside office hours.

But is it all good? If a lot of daily secretarial work can be done automatically, surely this will mean that fewer secretaries will be needed. Another worry is the increasing medical problems related to work with visual display units(显示器). The case of a slow loss of sight among people using word processors seems to have risen greatly. It is also feared that if a woman works at a VDU for long hours, the unborn child in her body might be killed. Safety screens to put over a VDU have been invented but few companies in England bother to buy them.

Whatever the arguments for and against word processors, they are a key feature of this revolution in office practice.

1Ten years ago, large computers were only used by large companies because       .

A. small companies did not have enough money to buy such expensive computers

B. large computers could not do the work that small companies can do today

C. large computers did not come onto the market

D. small companies did not need to use this new technology

2According to the writer, the main progress made in office work over the last ten years is     .

A. the saving of time and money

B. the use of computers in big companies

C. the wide use of word processors

D. the decreasing number of secretaries

3Which of the following statement is NOT true?

A. There are both advantages and disadvantages in using a word processor.

B. The British companies care much for the health of the people using word processors.

C. The technology in the field of computers has been greatly advanced over the last ten years.

D. Using word processors, secretaries can get more time to do more interesting work for their bosses.
