Hunting for a job late last year, lawyer Gant Redmon stumbled across CareerBuilder, 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-mails them when a matching position is posted in the database. Redmon chose the keywords 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 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 CareerSite’’ 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 CareerSite. 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 ann themselves when negotiating for a raise. Although happily employed, Redmon maintains his agent at CareerBuilder. "You always keep your eyes open," he says. Working with a personal search agent means having another set of eyes looking out for you. Which of the following is true according to the text

A:Personal search agents are indispensable to job-hunters. B:Some sites keep E-mailing job seekers to trace their demands. C:Personal search agents are also helpful to those already employed. D:Some agents stop sending information to people once they are employed.

Prince Klemens Von Metternich, foreign minister of the Austrian Empire during the Napoleonic era and its aftermath, would have no trouble recognizing Google. To him, the world’s most popular web-search engine would closely resemble the Napoleonic France that in his youth humiliated Austria and Europe’s other powers. Its rivals—Yahoo!, the largest of the traditional web gateways, eBay, the biggest online auction and trading site, and Microsoft, a software empire that owns MSN, a struggling web portal—would look a lot like Russia, Prussia, and Austria. Metternich responded by forging an alliance among those three monarchies to create a "balance of power" against France. Google’s enemies, he might say, ought now to do the same thing.
Google announced two new conquests on August 7th. It struck a deal with Viacom, an "old" media firm, under which it will syndicate video clips from Viacom brands such as MTV and Nickelodeon to other websites, and integrate advertisements into them. This makes Google the clear leader in the fledgling but promising market for web-video advertising. It also announced a deal with News Corporation, another media giant, under which it will pro-vide all the search and text-advertising technology on News Corporation’s websites, including My Space, an enormously popular social-networking site.
These are hard blows for Yahoo! and MSN, which had also been negotiating with News Corporation. Both firms have been losing market share in web search to Google over the past year—Google now has half the market. They have also fallen further behind in their advertising technologies and networks, so that both make less money than Google does from the same number of searches. Safa Rashtchy, an analyst at Piper Jaffray, a securities firm, estimates that for every advertising dollar that Google makes on a search query, Yahoo! makes only 60-70cents. Last month Yahoo! said that a new advertising algorithm that it had designed to close the gap in profitability will be delayed, and its share price fell by 22% , its biggest-ever one-day drop.
MSN is further behind Google than Yahoo! in search, and its parent, Microsoft, faces an even more fundamental threat from the expansionist new power. Many of Google’s new ventures beyond web search enable users to do things free of charge through their web browsers that they now do using Microsoft software on their personal computers. Google offers a rudimentary but free online word processor and spreadsheet, for instance.
The smaller eBay, on the other hand, might in one sense claim Google as an ally. Google’s search results send a lot of traffic to eBay’s auction site, and eBay is one of the biggest advertisers on Google’s network. But the relationship is imbalanced. An influential re-cent study from Berkeley’s Haas School of Business estimated that about 12% of eBay’s revenues come indirectly from Google, whereas Google gets only 3% of its revenues from eBay. Worst of all for eBay, Google is starting to undercut its core business. Sellers are setting up their own websites and buying text advertisements from Google, and buyers are using its search rather than eBay to connect with sellers directly. As a result, "eBay would be wise to strike a deep partnership with Yahoo! or Microsoft in order to regain a balance of power in the industry," said the study’s authors, Julien Decot and Steve Lee, sounding like diplomats at the Congress of Vienna in 1814.

A:show the web-search engine Google has become the most profitable site in the world. B:emphasize the importance of forging an alliance among the competitors. C:draw an analogy between present Internet competition and past European power distribution. D:stress the fact that even Microsoft can’t compete with Google.
