交谈式（Interactive）

Do your children lie to you and their friends about their activities online Do they feel empty, depressed and irritable when not at the computer Do they have problems with school or work, yet they always seem to feel energized again when they are at the computers surfing the internet If you answered "yes" to one or even more of the above questions, your children are suffering from internet addiction. The amount of time kids spend online is a source of headaches for many parents. At first, parents welcomed the Internet into their homes, believing they were opening up an exciting new world of educational opportunities for their children. But soon, to their disappointment, instead of using the Internet for homework or research, their kids were spending hours instant chatting with friends, playing online games or even talking to strangers in chat rooms, which is posing real dangers to the children.
Maintaining a healthy balance between entertainment media and other activities in children’s lives has always been a challenge for parents. The Internet has made this challenge even more difficult. The engaging nature of Internet communications and interactive games means many children and teens have trouble controlling the time they spent online.
Unfortunately, parents and teachers do not realize that there is a problem until it becomes serious. To make it worse, Internet addiction is not widely recognized by the medical community. (Mental health practitioners continue to debate whether this behavior is an "addiction," with some preferring to identify it as "behavior control problems.
Children and young people can easily become "hooked" on online activities such as multi-user games, instant messaging with their pals and chat rooms. The children most easily influenced, according to the Computer-Addiction Services at Harvard Medical School, are those who are "lonely and bored or from families where nobody is at home to relate to after school."
Children who are unpopular or shy with peers are often attracted to the opportunities for creating new identities in online communities. Boys, in particular, are frequent users of online role-playing games, where they have new identities and interact with other players. Although playing these games with thousands of other users may appear to be a social activity, for the troubled child or teen, too much playing can further separate them from friends and peers.
What is the "challenge" the author is talking about in paragraph 2

A:Children tend to have too much entertainment activities. B:Internet communications and interactive games are absorbing too much time and energy of the children. C:The children planed their time and activities in a horrible way. D:To arrange the media entertainment and other activities in a reasonable way.

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 people with lower self-esteem were more likely to spend more than an hour a day on Facebook and were more prone to post self-promo-tional photos ( striking a pose or using Photoshop, for example). Narcissists were also more likely to showcase themselves through status updates (using phrases like "I’m so glamorous I bleed glitter") and wall activity (posting self-serving links like " My Celebrity Look-alikes" ).
Self-esteem and narcissism are often interrelated but don’t always go hand in hand. Some psychologists believe that narcissists--those who have a pervasive pattern of grandiosity, a need for admiration, as well as a lack of sympathy--unconsciously inflate their sense of self-importance as a defense against feeling inadequate. Not enough empirical research has been produced to confirm that link, although Mehdizadeh’s study seems to support it. Because narcissists have less capacity to sustain intimate or long-term relationships, Mehdizadeh thinks that they would be more drawn to the online world of virtual friends and emotionally detached communication.
Although it seems that Facebook can be used by narcissists to fuel their inflated egos, Mehdizadeh stops short of proclaiming that excessive time spent on Faeebook can turn regular users into narcissists. She also notes that social-networking sites might ultimately be found to have positive effects when used by people with low self-esteem or depression. "If individuals with lower self-esteem are more prone to using Facebook," she says, "the question becomes, ’ Can Facebook help raise self- esteem by allowing patients to talk to each other and help each other in a socially interactive environment’ I don’t think it’s necessarily a bad thing that people with low self-esteem use Facebook. /
Mehdizadeh may think that______.

A:Facebook will make people abnormal B:people with low self-esteem could increase their confidence by Facebook C:Facebook is socially interactive environment D:narcissists with lower self-esteem don’t like to communicate mood

Imagine browsing a website when an attractive ad for lingerie catches your eye. You don’t click on it, merely smile and go to another page. Yet it follows you, putting up more racy pictures, perhaps even the offer of a discount. Finally, annoyed by its persistence, you frown. "Sorry for taking up your time," says the ad, and promptly stops further disturbance. Creepy. But making online ads that not only know you are looking at them but also respond to your emotions will soon be possible, thanks to the power of image-processing software and the common existence of tiny cameras in computers and mobile devices.
Uses for this technology would not, of course, be confined to advertising. There is ample scope to apply it in areas like security, computer gaming, education and health care. But advertisers are among the first to embrace the idea in earnest. Advertising firms already film how people react to ads, usually in an artificial setting. The participants’ faces are studied for positive or negative feelings. A lot of research has been done into ways of categorizing the emotions behind facial expressions. Some consumer-research companies also employ cameras to track eye movements so they can be sure what their subjects are looking at. This can help determine which ads attract the most attention and where they might be placed for the best effect on a web page.
One of the companies doing such work, Realeyes, which is based in London, has been developing a system that combines eye-spying webcams with emotional analysis. Mihkel Jaatma, who founded the company in 2007, says that his system is able to detect a person’s mood by plotting the position of facial features, such as eyebrows, mouth and nostrils, and employing clever programs to interpret changes in their alignment—as when eyebrows are raised in surprise, say. Add eye-movement tracking, hinting at which display ads were overlooked and which were studied for any period of time, and the approach offers precisely the sort of quantitative data brand managers yearn for.
At present the system is being used on purpose-built websites with, for instance, online research groups testing the effect of various display ads. The next step is to make interactive ads. Because they can spot the visual attention given to them, as well as the emotional state of the viewer, these ads could change their responses.
As similar technologies become widespread, privacy concerns will invariably increase. People would need to give consent to their webcams being used in this way, Mr. Jaatma admits. One way to persuade Internet users to grant access to their images would be to offer them discounts on goods or subscriptions to websites.
According to Paragraph 2 ,the study of people’s emotional responses to ads

A:contributes to the wide use of interactive ads in various fields. B:helps to improve the way in which online ads are displayed. C:classifies the different emotions of the subjects in real life. D:opens a door to a better acceptance of online advertisements.
