"Looking at the signs now I get a feeling of amazement, mixed with sadness."Building a neon sign is an art practiced by 29 trained on the job to mold glass tubes into 30 shapes and letters. They fill these tubes withgases that glow when 31 . Neon makes orange,while other gases make yellow or blue. It takes many hours to craft a single sign.Blance spent a week in Hong Kong and 32 more than 60 signs; 22 of them appear in the series that capture the signs lighting up lonely streets—an 33 that makes it easy to admire their colors and craftsmanship. "I love the beautiful, handcrafted, old-fashioned 34 of neon,"says Blance.

For questions 1-7,markY (for YES)if 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.For questions 8-10,complete the sentences with information given in the passage.Computer CrimeA computer crime is generally defined as one that involves the use of computers and software for illegal purposes. This doesn’t mean that all the crimes are new types of crime. On the contrary, many of these crimes, such as embezzlement of funds, the alteration of records, theft, vandalism, sabotage, and terrorism, can be committed without a computer. But with a computer, these offenses can be carried out more quickly and with less chance that the person responsible for the crime will be discovered.Computer crimes are on the rise and have been for the lasttwelve years. Just how much these computer crimes cost the American public is in dispute, but estimates range from ?$3 billion to ?$5 billion annually. Even the FBI, which attempts to keep track of the growth or decline of all kinds of crimes, is unable to say precisely how large a loss is involved; however, it estimates that the average take from a company hit by computer crime is ?$600,000. A number of reasons are given for the increase in computer crime: (A) more computers in use and, thus, more people who are familiar with basic computer operation; (B) more computers tied together in satellite and other data—transmission networks; and (C) the easy access of microcomputers to huge mainframe data bases.The CriminalMovies and newspaper stories might lead us to believe that most computer crimes are committed by teenage “hackers”—brilliant and basically good children who let their imagination and technical genius get them into trouble. But a realistic look at the crimes reveals that the offender is likely to be an employee of the firm against which the crime has been committed, i.e., an “insider”.Difficulty of Detection and PreventionGiven the kind of person who commits a computer crime and the environment in which the crime occurs, it is often difficult to detect who the criminal is. First of all, the crime may be so complex that months or years go by before anyone discovers it.Second, once the crime has been revealed, it is not easy to find a clear trail of evidence that leads back to the guilty party. After all, l ooking for “weapons” or fingerprints does not occur as it might in the investigation of more conventional crimes.Third, there are usually no witnesses to the computer crime,even though it may be taking place in a room filled with people. Who is to say if the person at the next terminal, calmly keying in data, is doing the company’s work or committing a criminal act?Fourth, not enough people in management and law enforcement know enough about computer technology to prevent the crimes. Authorities have to be familiar with the computer’s capabilities within a given situation to guard against its misuses. In some large cities, such as Los Angeles, police departments have set up specially trained computer crime units.But even when an offender is caught, the investigators, attorneys (律师), judges, or juries may find the alleged crime too complicated and perplexing to handle. More attorneys are specializing in computer law and studying the computer’s potential for misuse.After a computer crime has been discovered, many companies do not report it or prosecute (起诉) the person responsible. A company may not announce the crime out of fear that the pubic will find out the weaknesses of its computer system and lose confidence in its organization. Banks, credit card companies, and investment firms are especially sensitive about revealing their vulnerabilities (脆弱性) because they rely heavily on customer trust.To avoid public attention, cautious companies will often settle cases of computer tampering out of court. And if cases do go to trial and the offenders are convicted, they may be punished only by a fine or light sentence because the judge or jury isn’t fully trained to understand the nature and seriousness of the crime.Not all companies are timid in apprehending computer criminals. For example, Connecticut General Life InsuranceCompany decided it had to get tough on violators. So when the company discovered that one of its computer technicians had embezzled ?$200,000 by entering false benefit claims, it presented i t findings to the state’s attorney and aided in the prosecution of the technician. The technician was found guilty and sentenced to prison, not just for the computer misuse, but also for grand theft and insurance fraud. Connecticut General now has a policy of reporting all incidents of theft or fraud, no matter how small.1. The FBI knows exactly how large a loss is involved in computer crimes.2. It has become easy for microcomputer owners to use huge mainframe data bases.3. It is implied in the Paragraph 3 that most computer criminals are the employees of the concerned companies.4. Many companies don?t report computer crimes because law procedures against computer crimes usually cost a lot of money.5. When computer crime takes place in a room filled with people, there are usually many witnesses to the crime.6. The passage is mainly about the increase of computer crimes in America and the difficulties in combating computer crimes.7. Computer crimes are on the rise because more cheap microcomputers are available.8. According to the passage, computer crimes has been on the rise for thelast years.9. Connecticut General Life Insurance company is cited as of companies that took serious measures to fight against computercrimes.10. Banks, credit card companies, and investment firms are especially sensitive about revealing their vulnerabilities because they place too much reliance on .参考答案：1. N.该句句意为:美国联邦调查局确切知道计算机犯罪造成了多大损失。

But financial experts 50 parents to start college savings plans when their child is Still very young.All fifty states and the District of Columbia 51 what are called 5-29 plans. These plans are named after the part of the federal tax law that created them in 1996. States use private investment companies to operate the 52 of the programs.Every state has its own rules 53 5-29 plans. Some of the plans are 54 of state taxes. And all are not required to pay federal taxes. However, the government could start to tax withdrawals in 2011 if Congress does not change the law.5-29 plans include investment accounts that increase or decrease in value with the investments they contain. Families must decide how 55 they want to put money into stocks, or other investments.Another kind of 5-29 plan lets parents begin to pay for their child’s education in 56 and long before their child starts college. This kind of savings program is called a prepaid tuition plan. The money goes into an accountThere is progress toward a possible treatment for lung diseases such as SARS (severe acute respiratory syndrome). Researchers have learned more about how the SARS virus works: it 47 with a system in the body that uses enzymes (酶) to control blood pressure and fluid balance. Scientists say the virus 48 to an enzyme known as ACE-two. The virus blocks the enzyme, permitting fluid to enter the lungs.A team from Europe and Asia reported the 49 in Nature Medicine. Doctor Josef Penninger of the Institute of Molecular Biotechnology in the Austrian Academy of Sciences was the 50 writer of the report. The discovery could lead to a new 51 of treating not just SARS but also other diseases that can cause lung failure. These include avian flu (禽流感) and influenza in humans.The first 52 of SARS were discovered in Guangdong province, in southern China, in November of 2002. SARS was not 53 as a worldwide threat until March of 2003. The disease spread to 26 countries, most of them in the Asia-Pacific area. An estimated 8, 000 people had SARS. More than 770 of them died, or about 10% , a 54 high rate.The World Health Organization warned people not to travel to 55 areas. The 56 hurt international travel and business. The WHO says the disease stopped spreading by July of 2003. As a result of SARS, the health agency got new powers to act before a government officially announces a crisis.（4）To call something “marginal” means it is not very good. Farmers have their own way to 47 marginal land: It is the last to be planted under good conditions, and has the 48 to be avoided under poor conditions. Low 49 soil is not the only reason land could be considered marginal. It might be in an area where rainfall is 50 or where a hillside might rise too steeply.There are uses for marginal land, however. Most often it is used as grassland. Grasses provide excellent51 for grazing (吃草) animals like cattle, sheep and goats. Grass seed can be bought from a foreign supplier or52 grasses can be used. However, using marginal land for grazing is not a simple issue. There is a 53 of overgrazing. Cattle can damage the crops by eating down to the roots. Also, the weight of the animals crushes the soil and can make it too hard for growing. A(n) 54 way to reduce the harm is to move animals from one field to another. This method is known as rotational grazing (循环放牧) which is extremely important for marginal land.Another use for marginal land is for tree crops. Studies have 55 that the white pine and loblolly pine (火炬松) are two kinds of trees that grow well on such land. They grow fast and provide good quality wood. Another tree is the poplar (白杨), found in many parts of the world.Failure to take the care needed to protect marginal lands can make a bad situation worse. But goodChina is casting such a huge shadow on the United States that many Americans are trying hard to learn the Chinese language with an effort to keep their competitive edge."Interest in learning Chinese among American youth and their parents has grown 47 in the past five years," said Vivien Stewart, vice president at the Asia Society, a US group trying to bridge the 48 between Americans and the peoples of Asia and the Pacific.China's rapid progress is driving the interest to 49 the language, experts say. "The Chinese rich cultural traditions and 50 economy mean that it is now essential for all of our students to be better prepared to engage them and seize opportunities together," said Michael Levine, Asia Society' s executive director of education.A 2004 College Board survey found that 2,400 high schools--an 51 number--would be interested in52 the Advanced Placement (AP) courses in Chinese language and culture when the courses become available in 2006.China, the world' s most populous ( 人口稠密的) nation, is 53 to the United States because it is a leading trader, consumer and investor. It has 54 the United States as the world's largest consumer and could become the second largest economy in the world, in the next two to three decades.Even though the US State Department has regarded the Chinese language extremely important to national prosperity , the" 55 conditions to support recruitment of students and teachers as well as the growth of high（6）Can money buy happiness? Yes, 47 the authors of a new study---but only to a point.Psychology has shown that richer people generally rank the overall quality of their lives more 48 than poorer people do. At the same time, their actual happiness seems to be 49 less by their ability to buy more than by being able to keep up with those with comparable resources in their own age group."Our findings point to the possibility that, rather than promoting overall happiness, continued income growth could 50 an ongoing consumption race where people have to consume more and more, just to maintain a 51 level of happiness," writes Glenn Firebaugh of Pennsylvania State University.The study was 52 at the American Sociological Association's 100th Annual Meeting. Whether the rich are happier as a whole than their less 53 fellows is becoming an increasingly hot topic for debate. Recent years have 54 many writings on the "science of happiness." Richer people are happier because money can help purchase goods and services and it is the 55 of these materials that increases one's enjoyment of life and one's sense of well-being. Firebaugh and his colleagues measured the age, total family income, and general happiness of 56 aged 20 to 64, generally considered the working lifespan (工作寿命) for most Americans.Regardless of such standards as physical health, education, and marital status (婚姻状况), people's happiness was affected by what others earned. The higher the income of others in one's age group, the lower one'sKitchen duties may have traditionally been viewed as women’s work, but not at the White House.
