A.正功能

B.负功能

C.潜功能

D.隐功能

答案

参考答案:A

解析:从某一现象所起的作用的基本性质的角度来分,功能可以分为正功能和负功能。所谓正功能是指所发挥的正面的、积极的、支持性的作用。当甲对乙发生了积极影响时,我们就可以说甲对乙具有正功能。比如,可以说,最低生活保障制度对改善贫困群体的生活状况具有正功能。如果甲对乙产生了消极的、负面的影响,就可以说甲对乙具有负功能。比如,父母对子女过分严厉的管教可能会导致子女的逃避心理,这种管教就是负功能。

Targeting teens

But using the Web also makes teens a target. Posting too much personal information for those millions of cyber eyes to see can cause some big problems and can even invite a threat to your life.

As Mary learned, not everyone on the Internet is who he or she says they are. Adults will sometimes pose as other teens, posting fake photos and nice messages to gain trust. They use their fake identity to access the personal information of others, such as home address, phone number, or school name.

"That's not the most common scenario", says David Finkelhor, a sociology professor at the University of New Hampshire. "Only 3 percent of teens aged 10 to 18 who use the Internet report being asked to meet offline. But the danger is real.

Safety measures

Mary's My Space profile is set to "private", which means that only the people she adds under the "friend" category can access her page. She also doesn't have any pictures of herself on her site. The only self-identifying material she has posted is her name, grade, and a list of hobbies.

"People can only add me if they know my last name or my e-mail, "Mary says. " I don't want random people to see my profile. I just go online to talk to my friends."
