Questions are based on the following passage.
The act of Googling oneself has become the digital age's premiere guilty pleasure an activity enjoyed by all and admitted by few. The phenomenon has even been the subject of scholarly research. Last year, a study concluded that the practice of self-Googling can partly be traced to a rise in narcissism (神创论) in society, but that it is also an attempt by people to identify and shape their personal online "brand".
The reason people search for themselves is that they're curious about what other people see when they search for their name. One problem is they don't have any control over the search results and they will never appear on the first page of the search results. If your name is Brian Jones and you're not the former Rolling Stones guitarist, you don't exist.
To give people a bit more control over search results, Google introduced a feature this week called a "Google profile" which users can create, so that a little personal information appears at the bottom of US name search pages. Once users create a Google profile, their names, occupation, locations and photos appear in a box on the first page of the search results for their names. Besides, there's a link to a full Google profile page that in many ways resembles a Facebook page.
The similarity to Faeebook is no accident. By giving users a little control over tlie results that appear on a search for their names, Google hopes to establish a social network base and take on wildly popular sites like Facebook and MySpace. Facebook users who otherwise couldn't be bothered to set up a separate profile page on Google might find the idea appealing if it gives them some control over the Google search results for their names.
The more information you add to your profile, the higher your page is likely to be ranked on a Google search for your name and associated keywords, such as the name of your hometown, your job title or where you work or go to school. And the more richly detailed your Google profile is, the more Google knows about you. There's no advertisement attached to Google profiles, but in the future, the company could easily sell ads targeted to your personal details, much as they've already done on Gmail.
