问题     It turns out you can size up personality just by looking at a person’s Facebook profile. While that may not seem like a big deal, it is providing fodder for academics who are trying to predict temperament based on the things we post online. If such predictions prove accurate, employers may have good reason to poke around our Facebook pages to figure out how we would get along with others at the office. And Pentagon officials want to use personality assessments to make better decisions on and off the battlefield.
    A recent study by researchers at the University of Maryland predicted a person’s score on a personality test to within 10 percentage points by using words posted on Facebook. " Lots of organizations make their employees take personality tests," said Jennifer Golbeck, an assistant professor of computer science and information studies at the University of Maryland. "If you can guess someone’s personality pretty well on the Web, you don’t need them to take the test. "
    Golbeck and her colleagues at the university’s Human-Computer Interaction Lab—where she’s the co-director—surveyed the public profiles of nearly 300 Facebook users this year. They looked at users ’ descriptions of their favorite activities and membership in political organizations. They also looked at Facebook’s public "About Me" and "Blurb" sections.
    The 300 participants then took a standard psychological exam that measures the "big five" personality traits: openness to experience, conscientiousness, extroversion, agreeableness and neuroticism.
    People who tested as extroverts on the personality test tended to have more Facebook friends, but their networks were more sparse than those of neurotics, meaning that their friends were less likely to know one another than were the friends of other Facebook users. People who tested as neurotic had more " dense" networks of people who know one another and share similar interests.
    The researchers also found that people with long last names tended to have more neurotic traits, perhaps because "a lifetime of having one’s long last name misspelled may lead to a person expressing more anxiety and quickness to anger," according to the study. People who tested high on the neurotic scale also tended to use a lot of anxiety-associated words, such as "fearful" and "nervous" , on their Facebook posts. They also use words describing ingestion: "pizza" , "dish" , "eat".
    Golbeck says she can’t explain that last correlation. "You’d have to get a psychologist on that one," she said. "It could be that people that are neurotic talk more about what they are eating. It could be a deep correlation that we can’t understand on the surface. "
Which of the following best summarizes the main idea of the passage?
选项 A、Facebook profiles serve as a new approach of personality assessment.
B、Two kinds of temperament can be discovered through lexical analysis.
C、Network can provide more materials for psychological research.
D、Facebook profiles reveal personality traits to researchers.
答案D
解析 主旨题。文章介绍了研究者对Facebook个人资料进行分析，探究网络习惯与用户性格特点的相关性，因此[D]项最为准确地概括了本文主旨，故为答案。而利用Facebook个人资料进行性格分析还停留在研究阶段，不能成为性格评估的新方法，故排除[A]；[B]范围过窄，且偏离了文章的主要意思，也应排除；而[C]过于宽泛，文章只提到Facebook的个人资料，并没有说整个网络对心理研究的作用，故排除。
