______have come up with the solutions to the problem.

Internet is a global network that connects other computer networks, together with software and protocols for controlling the movement of data. The Internet, often referred to as "the Net", was initiated in 1969 by a group of universities and private research groups funded by the US Department of Defense. It now covers almost every country in the world. Its organization is informal and deliberately nonpolitical its controllers tend to concentrate on technical aspects rather than on administrative control. The Internet offers users a number of basic services including data transfer, electronic mail, and the ability to access information in remote databases. A notable feature is the existence of user groups, which allow people to exchange information and debate specific subjects of interest. In addition, there are a number of high-level services. For example, MBONE allows the transmission of messages to more than one destination. It is used in videoconferencing. The World Wide Web, known as "the Web", is another high level Internet service, developed in the 1990s in Geneva. It is a service for distributing multimedia information, including graphics, pictures, sounds, and video as well as text. A feature of the World Wide Web is that it allows links to other related documents elsewhere on the Internet. Documents for publication on the Web are presented in a form known as HTML (Hyper Text Markup Language). This allows a specification of the page layout and typography as it will appear on the screen. It also allows the inclusion of active links to other documents. Generally, these appear on the screen display as highlighted text or as additional icons. Typically, the user can use a mouse to "click" on one of these points to load and view a related document. Many commercial and public organizations now have their own Web site (specified by an address code) and publish a "home page", giving information about the organization. Up to the mid 1990s, the major users of the Internet were academic and research organizations. This has begun to change rapidly with individual home users linking in through commercial access providers and with a growing interest by companies in using the Internet for publicity, sales, and as a medium for electronic publishing. At the same time, there are problems with the flow of information across national borders, bringing in debates about copyright protection, data protection, the publication of pornography, and ultimately political control and censorship.

Do you remember all those years when scientists argued that smoking would kill us but the doubters insisted that we didn"t know for sure? That the evidence was inconclusive, the science uncertain? That the antismoking lobby was out to destroy our way of life and the government should stay out of the way? Lots of Americans bought that nonsense, and over three decades, some 10 million smokers went to caily graves. There are upsetting parallels today, as scientists in one wave after another try to awaken us to the growing threat of global warming. The latest was a panel from the National Academy of Sciences, enlisted by the White House, to tell us that the Earth"s atmosphere is definitely warming and that the problem is largely man-made. The clear message is that we should get moving to protect ourselves. The president of the National Academy, Bruce Alberts, added this key point in the preface to the panel"s report "Science never has all the answers but science does provide us with the best available guide to the future, and it is critical that out nation and the world base important policies on the best judgments that science can provide concerning the future consequences of present actions. Just as on smoking voices now come from many quarters insisting that the science about global warming is incomplete, that it"s OK to keep pouring fumes into the air until we know for sure. This is a dangerous game: by the 100 percent of the evidence is in, it may be too late. With the risks obvious and growing, a prudent people would take out an insurance policy now. Fortunately, the White House is starting to pay attention. But it"s obvious that a majority of the president"s advisers still don"t take global warming seriously. Instead of a plan of action, they continue to press for more research—a classic ease of "paralysis by analysis". To serve as responsible stewards of the planet, we must press forward on deeper atmospheric and oceanic research. But research alone is inadequate. If the Administration won"t take the legislative initiative, Congress should help to begin fashioning conservation measures A bill by Democratic Senator Robert Byrd of West Virginia, which would offer financial incentives for private industry is a promising start. Many see that the country is getting ready to build lots of new power plants to meet our energy needs. If we are ever going to protect the atmosphere, it is crucial that those new plants be environmentally sound.

Until recently most historians spoke very critically of the Industrial Revolution. They【B1】that in the long run industrialization greatly raised the standard of living for the【B2】man. But they insisted that its【B3】results during the period from 1740 to 1840 were widespread poverty and misery for the【B4】of the English population.【B5】contrast, they saw in the preceding hundred years from 1640 to 1740, when England was still a【B6】agricultural country, a period of great abundance and prosperity. This view,【B7】is generally thought to be wrong. Specialists【B8】history and economics, have【B9】two things: that the period from 1640 to 1740 was【B10】by great poverty, and that industrialization certainly did not worsen and may have actually improved the conditions for the majority of the populace.

Ernest Hemingway wrote a short story called " The Capital of the World. " In it he tells about a Spanish father who wants to reconcile(和解)with his son who has run away to Madrid. In order to locate the boy he takes out this ad in the newspaper: "Paco, meet me at Hotel Montana at noon on Tuesday. All is forgiven. Love, Papa. " Paco is a common name in Spain, and when the father goes to the square he finds 800 young men named Paco waiting for their fathers. What drew them to the hotel? As Hemingway tells it, it was the words "All is forgiven. " The father did not say, "All WILL BE forgiven IF you do this or that. " Not, "All WILL BE forgiven WHEN you do such and such." He simply says, "All is forgiven. " No strings attached. And that"s the hard part—un-attaching the strings. The origin of the expression "no strings attached" may go back to ancient times when documents were written on parchment(羊皮卷)that were rolled up and secured with a string. The Babylonian Talmud(犹太法典)tells of a man who gives his wife a bill of divorce on such a parchment, but holds onto the string so that he can snatch it back, should he choose to do so. The divorce, therefore, is not considered valid since he will not give it freely. Similarly, love, forgiveness or friendship that is given with strings attached are not valid, since they can be snatched back at any time.

This country, as Lincoln said, belongs to the people. So do the natural resources which make it rich. They supply the basis of our prosperity now and hereafter. In preserving them, which is a national duty, we must not forget that monopoly is based on the control of natural resources and natural advantages, and that it will help the people little to conserve our natural wealth unless the benefits which it can yield are given back to the people. Let us remember, also, that conservation does not stop with the natural resources. The principle of making the best use of all we have requires that we stop the waste of human life in industry and prevent the waste of human welfare which flows from the unfair use of concentrated power and wealth in the hands of men whose eagerness for profit blinds them to the cost of what they do. We have no higher duty than to promote the efficiency of the individual. There is no surer road to the efficiency of the nation.

Effective prevention against physical harms has never been ______ urgently needed, especially in schools.

Astronaut Jim Voss has enjoyed many memorable moments in his career, including three space flights and one space walk. But he recalls with special fondness a decidedly earthbound(只在地球上的) experience in the summer of 1980 when he participated in the NASA-ASEE Summer Faculty Fellowship Program. Voss, then a science teacher at West Point was assigned to the Marshall Space Flight Center"s propulsion(推进) lab in Alabama to analyze why a hydraulic fuel pump seal on the space shuttle was working so well when previous seals had failed. It was a seemingly tiny problem among the vast complexities of running the space program` Yet it was important to NASA because any crack in the seal could have led to destructive results for the astronauts who relied on them. "I worked a bit with NASA engineers, "says Voss, "but I did it mostly by analysis. I used a handheld calculator, not a computer, to do a thermodynamic(热力学的) analysis. "At the end of the summer, he, like the other NASA-ASEE fellows working at Marshall summarized his findings in a formal presentation and detailed paper. It was a valuable moment for Voss because the ASEE program gave him added understanding of NASA, deepened his desire to fly in space, and intensified his application for astronaut status. It was not an easy process. Voss was actually passed over when he first applied for the astronaut program in 1987. Since then he has participated in three space mission. The 50-year-old Army officer, who lives in Houston, is now in training for a four-month mission as a crew member on the International Space Station starting in July 2000. Voss says the ASEE program is wonderful for all involved. "It brings in people from the academic world and gives NASA a special property for a particular period of time. It brings some fresh eyes and fresh ideas to NASA, and establishes a link with colleges and universities", Voss explains". There is an exchange of information and an exchange of perspectives that is very important". For the academic side, Voss says, the ASEE program also "brings institutions of higher learning more insight into new technology. We give them an opportunity to work on real-world problems and take it back to the classroom".

These days a green building means more than just the color of the paint. Green building can also refer to environmentally friendly houses, factories, and offices. Buildings account for 65 percent of total U.S. electricity use. But green buildings can reduce energy and water use. Also, the buildings are often located near public transportation such as buses and subways, so that people can drive their cars less. That could be good for the environment, because cars use lots of natural resources such as gasoline, and give off pollution. Green buildings are often built on previously developed land, so that the buildings don"t destroy forests or other wild habitats(栖息地). Marty Dettling is a project manager for a building that puts these ideas into action. The Solaire has been called the country"s first green residential high-rise building. According to Dealing, "We"ve reduced our energy consumption by one-third and our water by 50 percent. Not everyone is leaping to move into a green building, however. Some people think that features such as solar panels cost more money than more traditional energy sources. Despite this, Dettling hopes that green buildings will become common in the future. "It"s going to be big", she said.

In November of 1902, President Theodore Roosevelt was on a hunting trip in Mississippi. His hunt was going【B1】that day, and he couldn"t seem to find anything worth of【B2】his rifle. Then, his staff captured a black baby bear for the President to shoot, but he could not. The thought of shooting a bear that was tied to a tree did not seem sporting, so he【B3】the life of the baby bear and set it free Based on this story, a famous political cartoonist for the Washington Star drew a cartoon, which showed Teddy Roosevelt, rifle【B4】, with his back turned on a cute(可爱的) baby bear. Morris Michtom, owner of a Brooklyn toy store, was【B5】by the cartoon to make a stuffed baby bear. Intending it only as a display, he placed the stuffed bear in his toy store【B6】,and next to it placed a copy of the cartoon from the newspaper. To Michtom"s surprise, his store was flooded by customers【B7】to buy. He asked for and received President Roosevelt"s【B8】to use his name for the hand-sewn bears that he and his wife made, and the "Teddy Bear" was born! Michtom was soon manufacturing Teddy bear【B9】the thousands. The money from the sale enabled him, in 1903, to【B10】the Ideal Toy Company.

Certainly, the most popular method of traveling used by Americans is the privately-owned automobile. The vast majority of Americans have a car, and many families have two.【31】during your visit to the United States, you may decide to rent a car to travel outside the city or to travel to other parts of the country.
