Section B
Directions: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A, B, C and D. You should decide on the best choice.
"The Google brand has taken on a life of its own," concedes Jim Lanzone, the boss of Ask. com, the fourth-largest but fastest-growing search engine, and this simultaneously frustrates and delights him. It frustrates him bemuse people say they "Google" things even when they go to Ask or other engines to search the web; bemuse Google is considered, for no good reason (in his opinion), "the safe choice under pressure"; and bemuse many people "don't seem to want choice" and stick to Google out of mere inertia.
But it delights him, because Google, having made many enemies, must now fight many battles; and because Google, perhaps out of hubris, appears to be getting distracted. This month, for instance, Google unveiled a free online spreadsheet program, which, like many Google products, has little to do with web search and is meant to needle Microsoft, the world's largest software company, which has a near-monopoly on spreadsheets through Excel. Google, in other words, has impressive momentum, says Mr. Lanzone, but a good martial-artist can use his opponent's momentum to overcome him, so "we're using search aikido."
Yahoo!, the largest internet portal with about 400m users (of its e-mail, instant-messaging, music and other products), has come up with a strategy to differentiate its own search engine. Yahoo! has been at this game for only two years, but now has hundreds of engineers working on it. In contrast to the quasi-religious faith that Google places in its mathematical algorithms, says Eckart Walther, one of Yahoo!'s search bosses, Yahoo! is "about combining the best of people with the best of technology".
Ask is taking a different tack. It has come up with Expert Rank, an algorithm that also ranks web pages by incoming links and links by theme. So instead of using a web page's overall popularity to calculate its ranking, it finds the pages that are most popular among experts on a particular subject, a method that often returns better results than Google's. Ask also uses these thematic clusters to suggest the best ways to narrow or expand a search, a feature called "zoom" that is very popular. Chris Sherman of Search Engine Watch thinks that Ask is as good as Google for general web search — but better than Genie for finding online maps and images.
As for Microsoft, it has identified Google as a mortal threat to its business and has launched an all-out effort to catch up in online services in general, and in search in particular. Last winter, it tried to buy itself market share by negotiating with AOL for a merger — or at least an agreement under which AOL would switch from Google's search technology to MSN's; but Google pre-empted Microsoft and itself took a defensive stake in AOL. Microsoft has also hired former rivals who are well respected in the industry.
What is the central idea of this passage？
W: What can I do for you？
M: Well, I'm working on a term paper about the influence of television on recent United States presidential elections. I found a few of the books I need at the main library, but I was told that the library here at the graduate school had more specialized materials.
W: Of course it depends on what you want, but we do subscribe to a large number of journals. Since you' re working on such a broad topic, you'll probably have to do a lot of digging. It may take some time, but I' m sure you'll be able to find many articles relevant to your topic. We also have quite a few newspapers on microfilm.
M: I think I've come to the right place. How can I find out which journals you have？
W: I can give you a list of all of them. But if you want to search by author or by subject, you can use one of the computers over there in the comer. Everything we have is seen them.
M: What if I run across a reference to a research study that isn't available here？
W: You can request any outside material just by typing your request into the computer.
M: You mean you can get materials from other universities？
W: Not only from other universities, but from virtually any public or private library in the United States. The only limitation is that outside materials cannot be checked out.
