单选题 When Erik Robertson, an account executive at a San Francisco public relations agency, meets with conservative clients, he's always sure to wear a suit and tie. But with his video game client, short sleeves and an open-collar shirt are perfectly fine. His wardrobe choices aren't just based on what the clients will be wearing. Sometimes, he also wants to conceal the tattoos covering his arms and chest because he realizes they could alienate customers. 'You have to be smart and not risk offending current clients or new business prospects,' said Robertson, who is 29 years old. 'I'd also like to have my hands and neck tattooed, but I don't because I couldn't cover them. I'm just glad I didn't go overboard when I was in college. When the online jobs site CareerBuilder asked employers which personal appearance attributes would make them less likely to promote someone, piercings were named most often (37% of respondents), while visible tattoos ranked third (31%). However, this is not the case for many young workers today. A new Pew Research Center survey found that 38% of the respondents between the age of 18 to 29 in the US had at least one tattoo, and 23% had a piercing in a place other than their ear lobes. 'To attract and retain talent, businesses will have to overcome negative stereotypical views about body art,' said Barrie Gross, a human-resources consultant based in San Francisco. 'They need to ask whether it really matters to job performance and the company's reputation if someone has a nose ring or tattoo.' KPMG, the international accounting firm, advises its college recruits 'to remove visible body piercings and cover tattoos' at work. Similarly, Macy, the big US retailer, tells employees to avoid 'excessive' facial piercings and tattoos that distract or offend customers. A Macy's spokeswoman declined to explain what qualifies as 'excessive.' The degree of flexibility about body art may change with changing recruiting needs. When the US Army needed to attract more recruits for the wars in Iraq and Afghanistan, for instance, it relaxed its dress code to allow tattoos on the neck and hands. In interviewing hiring managers in Scotland, Andrew Timming, a reader in management at the University of St Andrews, found that they harbour mostly negative attitudes toward job candidates with visible tattoos. Even recruiters who were tattooed themselves held such views. But the hiring managers told Timming they wouldn't reject applicants because of their own bias, but rather because they believed customers would disapprove of body art.

单选题The history of the computer in the twentieth century is one of dramatic adaptation and expansion. The computer had modest beginnings in areas where it was used as a specialist tool. The first electronic computer was built in the 1930s and was solely for the use of undergraduate students in Iowa State University to handle mathematical computations in nuclear physics. In the 1960s an early version of the Internet, ARPPANET was used in computer science and engineering projects. However, only 10 years later computers were starting to change our life style, the way we do business and many other things and by the late 1980s' networks were expanding to embrace sections of the general public. Computerization has changed US high school education in many ways. Three different changes that consider being important. The first is the use of the computer as teaching aid for teachers. The next is the massive data storage and fast data retrieval facilitated by computer. Then comes the changes brought about by the introduction of simulation software. How prevalent is the use of computers in schools! As recently as the early 1980s only 20% of secondary science teachers in the USA were using microcomputers. However, since then high schools in the US have computerized rapidly. By 1987, schools had acquired about 1.5 million computers with 95% of public schools having at least one computer. Computers can be used as teaching aids both in schools and in homes. In schools, for example, teachers can plug a computer into an especially equipped overhead projector to bring texts, graphics, sound and videos into a classroom. By these multimedia computer animations, teachers can more readily attract and retain students' attention. Ann concludes that computer aided teaching can attract and motivate students who were dropping out when more traditional methods were being used. Let us now turn to the Internet. This is a global network connecting many local networks. Over the Internet, high school students can retrieve information and databases from every networked library around the world in seconds. The World Wide Web provides an easy way to access hard-to-find information. Students can now reach any library through the global network and find what they want. The final step is to download the scanned image. Though the slow transmission of signal through the network is a major limiting factor, it can still save us much time in finding useful information, and thus it is an invaluable tool to both high school teachers and students.
