1、大学英语四级模拟试卷 254及答案与解析 一、 Part I Writing (30 minutes) 1 For this part, you are allowed 30 minutes to write a composition on the topic: Does technological advancement bring more benefits or drawbacks to the world? You should write at least 120 words following the outline given below in Chinese: 1. 很多人认
2、为技术进步促进了人类社会的发展。 2. 也有很多人持反对意见,认为技术进步给人类带来的问题更多。 3. 谈谈你的看法。 二、 Part II Reading Comprehension (Skimming and Scanning) (15 minutes) Directions: In this part, you will have 15 minutes to go over the passage quickly and answer the questions attached to the passage. For questions 1-7, mark: Y (for YES) i
3、f the statement agrees with the information given in the passage; N (for NO) if the statement contradicts the information given in the passage; NG (for NOT GIVEN) if the information is not given in the passage. 1 The Father of the World Wide Web Tim Berners-Lee, who received one million euros ($1.2
4、million) cash prize for creating the World Wide Web, says he would never have succeeded if he had charged money for his inventions. “If I had tried to demand tees, . there would be no World Wide Web,“ Berners-Lee, 49, said on June 5 at a ceremony for winning the first Millennium Technology Prize, aw
5、arded by the Finnish Technology Award Foundation. “There would be lots of small webs,“ the prize committee agreed, citing the importance of Berners-Lees decision never to commercialize or patent his contributions to the Internet technologies he had developed, and recognizing his revolutionary contri
6、bution to humanitys ability to communicate. His creation spun a generation of youthful millionaires and billionaires, lit the spark for the New Economy and paved the way for massive new industries such as e-commerce. Burners-Lee, who is originally from Britain, has mostly avoided both the fame and t
7、he fortune won by many of his Internet colleagues. Despite his prize, he remained modest about his achievements. “I was just taking lots of things that already existed and added a little bit,“ said Berners-Lee, who now runs the standard-setting World Wide Web Consortium from an office at Massachuset
8、ts Institute of Technology. “Building the Web, I didnt do it all myself,“ he said. “The really exciting thing about it is that it was done by lots and lots of people, connected with this tremendous spirit.“ Berners-Lee indeed took concepts that had been well known to engineers since the 1960s, but i
9、t was he who saw the value of marrying them. Pekka Tarjanne, chairman of the prize committee, said “no one doubts who the father of file World Wide Web is, except Berners-Lee himself.“ Finnish President Tarja Halonen presented the biannual (一年两次的 )award, subsidized by the government. The cash prize
10、is among the largest of this kind, and Berners-Lee is the first recipient. The prize committee outlined the award to be given for “an outstanding innovation that directly promotes peoples quality of life, is based on human values and encourages sustainable economic development.“ “Isnt this like a de
11、finition of the World Wide Web?“ Tarjanne asked. Berners-lee first proposed the Web in 1989 while developing ways to control computers remotely at European Laboratory for Particle Physics, the European nuclear research lab near Geneva. He never got the project formally approved, but his boss suggest
12、ed he quietly tinker (摆弄 ) with it anyway. He fleshed out the core communication protocols (草案 ) needed for transmitting Web pages. By Christmas Day in 1990, he finished the first browser, called simply “World Wide Web.“ Although his inventions have under- gone rapid changes since then, the underlyi
13、ng technology is precisely the same. His recent project - which experts say is potentially as revolutionary as the World Wide Web itself - is called the Semantic Web. The project is an attempt to standardize how information is stored on the Internet. “It is an exciting new development that were maki
14、ng,“ he said. In his acceptance speech, Berners-Lee focused on technology as an evolving process that was just in the beginning. “All sorts of things, too long for me to list here, are still out there waiting to be done There are so many new things to make, limited only by our imagination,“ he said.
15、 “And I think its important for anybody whos going through school or college wondering what to do, to remember that now.“ For years, the British scientists colleagues have said that if computer science was a pure science, Mr. Berners-Lee would have merited a Nobel Prize for his invention. He did rec
16、eive a knighthood this year, but for the most part his name remains unknown to the masses who use his creation every day. “His picture belongs up on a wall with Thomas Edison and Alexander Graham Bell,“ said Rick Broad head, a technology consultant and author. “The Web will go down as one of the gre
17、atest innovations of all time. Think of the industries and jobs it has created. It has transformed the worlds economy in a way we cant even begin to imagine.“ The Internet had been in existence for nearly 20 years when Mr. Berners-Lee launched the worlds first website in August, 1991. But the Net wa
18、s little more than a collection of computers connected with cables. It didnt have a means of sharing information between different kinds of computers running different kinds of software. As a young scientist working at CERN in Geneva, Mr. Berners-Lee became sidetracked from his physics work as he so
19、ught a better way to organize and link electronic research documents. His solution was to connect documents and other information using hypertext links. The universal hypertext language he created allows all kinds of computers using all kinds of software to communicate with each other. The invention
20、 could have made him incredibly wealthy, even by Internet standards. But Mr. Berners-Lee never patented his creation, and by leaving it in the public domain he enabled the internet to adopt an open and universal method for sharing information. Many of the entrepreneurs and scientists who did use it
21、became rich. On his own website, he explains why he never sought to cash in: “It was simply that if the technology had been proprietary, and in my total control, it would probably not have taken off. The decision to make the Web an open system was necessary for it to be universal. You cant propose t
22、hat something be a universal space and, at the same time, keep control of it.“ The decision also sat well with his own modest character. “The fame thing I dont like,“ he confessed once. “Theres something very frustrating when you meet somebody at a party and they say, Oh, you invented the World Wide
23、 Web. Suddenly, theyre not talking to you any more.“ Its Berners-Lees world; we just live in it. But youd never get that impression from Sir Tim himself, the man with nary a thought of power or glory, fame or fortune. The computer wizard (奇才 ) dubbed (绰号为 ) the “father of the World Wide Web“ has rec
24、eived a knighthood for services to the Internet. As a Britain citizen, Berners-Lee is able to use the title “Sir Tim“. He said that it never occurred to him that his creation could lead to him receiving a knighthood. The modest, publicity-shy physicist is at pains to point out that he did not invent
