单选题Hunting for a job late last year, lawyer Gant Redmon stumbled across Career Builder, a job database on the Internet. He searched it with no success but was attracted by the site's "personal search agent". It's an interactive feature that lets visitors key in job criteria such as location, title, and salary, then e-mail them when a matching position is posted in the database. Redmon chose the key words legal, intellectual property, and Washington, D. C. Three weeks later, he got his first notification of an opening. "I struck gold," says Redmon, who e-mailed his resume to the employer and won a position as in-house counsel for a company. With thousands of career-related sites on the Internet, finding promising openings can be time consuming and inefficient. Search agents reduce the need for repeated visits to the databases. But although a search agent worked for Redmon, career experts see drawbacks. Narrowing your criteria, for example, may work against you, "Every time you answer a question, you eliminate a possibility," says one expert. For any job search, you should start with a narrow concept what you think you want to do — then broaden it. "None of these programs do that," says another expert. "There's no career counseling implicit in all of this." Instead, the best strategy is to use the agent as a kind of tip service to keep abreast of jobs in a particular database; when you get an e-mail, consider it a reminder to check the database again. "I would not rely on agents for finding everything that is added to a database that might interest me," says the author of a job-searching guide. Some sites design their agents to tempt job hunters to return. When Career Site's agent sends out messages to those who have signed up for its service, for example, it includes only three potential jobs—those it considers the best matches. There may be more matches in the database; job hunters will have to visit the site again to find them—and they do. "On the day after we send our messages, we see a sharp increase in our traffic," says Seth Peets, vice president of marketing for Career Site. Even those who aren't hunting for jobs may find search agents worthwhile. Some use them to keep a close watch on the demand for their line of work or gather information on compensation to arm themselves when negotiating for a raise. Although happily employed, Redmon maintains his agent at Career Builder. "You always keep your eyes open," he says. Working with a personal search agent means having another set of eyes looking out for you.

单选题A line in a song asks, "does anyone really know what time it is?" This question could easily apply to calendars! Did you know that our ideas about time are affected by religion? Different faiths use different types of calendars to measure time. Odd structures, such as Stonehenge in England, may have been used to measure time long ago. These ancient rocks stand in a circle like large, gray Legos. Some people think that the rocks relate to the position of the sun. No one knows how people moved them into this information, but it was probably a lot of work. If it was a calendar, it sure was a big one! The Aztecs also had a rock calendar that was related to the sun. They had a Sun Stone that showed their sun god in the center. The calendar you are probably most familiar is also based on the sun. The powerful Roman Emperor, Julius Caesar, first adopted the solar calendar in 46 B. C. The cycle of the year in a solar calendar is measured from one equinox to the next. A solar calendar has to be adjusted every so often to keep in time with the sun. In 1582, Pope Gregory XII I first authorized taking a few days out of every year for the purpose of adjusting the calendar. People didn't like this one bit because they thought they were losing time! It took centuries for Europeans to get used to this concept. Eventually, a system was worked out to add a single day to the calendar every four years. So it was synchronized with the seasons. The extra day made every fourth year 366 days long. These special years are called leap years, and we called the extra day to the month of February. If you know someone whose birthday is February 29, you know that he or she was born in a leap year. This calendar is called the Gregorian calendar, and it is used in the United States and other Christian countries. Muslims use a different kind of calendar. Their lunar calendar is based on the cycles of the moon, and it is completely different than a solar one. According to the Muslim holy book, the Koran, Allah said, "Truly, twelve months is the number of the months with God, according to the God's Book, ever since He created heaven and Earth. " A new Muslim month does not start until two reliable witnesses have seen the new moon. Muslim families often take walks in the evening to find the first yellow slice of the new moon to start Ramadan, their month-long fast.
