[填空题] Social Networking
A large but long-in-the-tooth technology company hoping to become a bigger force in online advertising buys a small start-up in a sector that everybody agrees is the next big thing. A decade ago, this was Microsoft buying Hotmail--the firm that established web-based e-mail as a must-have service for internet users, and promised to drive up page views, and thus advertising inventory, on the software giant’s websites. This month it was AOL, a struggling web portal (入口网站) that is part of Time Warner, an old-media giant, buying Bebo, a small but up-and-coming online social network, for $ 850m.

[单项选择]As high school students flock to social networking sites, campus police are scanning their Facebook and MySpace pages for tips to help break up fights, monitor gangs and prevent crime.

Social-networking sites offer users easy ways to present idealized images of themselves, even if those ideals don’t always square with their real-world personalities. Psychology researcher Soraya Mehdizadeh has discovered a way to poke through the offline-online curtain: she has used Faeebook to predict a person’s level of narcissism and self-esteem.
Mehdizadeh, who conducted the study as an undergraduate at Toronto’s York University, gained access to the Faeebook accounts of 100 college students and measured activities like photo sharing, wall postings and status updates; she also studied how frequently users logged on and how often they remained online during each session. Her findings were published recently in Cyberpsyehology, Behavior and Social Networking.
After measuring each subject using the Narcissism Personality Inventory and Rosenberg Self-Esteem Scale, Mehdizadeh, who graduated from York this past spring, discovered narcissists and p
A. like to hide themselves
B. maybe show the characters that are different from the real ones
