问题 单项选择题

随着人们对信息需求的日益增长,许多国家都在大力开发可视图文信息系统。这种系统把用户终端(计算机和电话机)通过现有的公用电信网与图文信息中心计算机的数据库连接起来,进行数据通信,向公众开放信息服务,使信息资源在最大范围内实现共享,这个系统亦称为可视数据系统。用户在家中只要通过操纵终端设备,就可以方便地向图文信息中心检索所需要的各种可视图文信息。各个用户可在电视机屏幕前分别与图文信息中心的计算机“对话”,而不只是被动地接收信息。这种可以进行人机对话的信息系统又称为交互(交互就是有问题有答案)可视信息系统。它是信息社会中一种比较理想的通信手段。这种可视信息系统自从1979年问世以来,至今已普及到几十个国家和地区,我国也已开通了可视图文通信业务。在可视图文系统中,用户与电视节目中心数据库或图像库直接通信,成为声音、图像综合以及娱乐、教育、信息一体化的通信手段。它也是实现办公自动化和家庭自动化的重要工具。交互电视信息系统使有线电视可供选择的频道增加到一、二百个,而且各家庭(个人)同发射台可以进行双向通信联络,用户不仅可以点播节目,还可以参与电视节目的制作。可视图文系统已经使人们的生活发生了一系列的改变。它给教学活动、生产管理等带来极大的方便。
可视图文系统最有效的领域要算是购物和预约订货了。顾客不出家门就可通过可视图文终端进行购物和款项的支付结算。

对可视图文信息系统表述错误的一项是( )。

A.它是实现办公自动化和家庭自动化的重要工具

B.交互可视信息系统是可视图文信息系统的一种

C.用户利用计算机在家中就能购物

D.用户操纵计算机参与电视节目制作已有十几年历史

答案

参考答案:B

解析: 选项ACD都能从原文中找到依据,B项不是对可视图文信息系统的表述。故选B。

Normally when I pop in to see my parents, my mum bursts out of the house with a big smile. Not today. "Your brother," she says, "he's showered twice this afternoon. Does he know how much it costs to run this house?" Are we limiting water now? I didn't think the recession(萧条) had got that bad. My poor brother is a boomerang kid. Like 60 percent of guys immediately after university, he's back at home. Graduating £15,000 in debt and faced with unpaid internships(实习期) or low wages thanks to the flooding of the market with graduates, a lot of twenty some things simply don't have the necessary income or parental support to live independently.

Three years after getting their degree, most graduates are still not earning above the average salary. They have a near 50 percent tax burden, thanks to student loan repayments and council tax on top of income tax and national insurance. Unless you have parents who can afford to finance what is effectively a second home for them, returning to the parental nest is often the only affordable option.

The boomerang effect is becoming even more pronounced thanks to the recession. One in four of those losing their job during the downturn is under 25. Only 13 percent of final-year students have jobs. Home is the only place many are going: 111,000 16-29 year olds moved back home in 2008, five times the average of previous years.

Boomeranging is bad news. It poses serious problems for parents' finances. They've already supported their children through university, topping up loans with handouts, averaging £12,300 in total, to keep twenty somethings afloat. Now their retirement savings are being eaten away by continuously dependent children.

It’s bad for the returning kids too. Ambitious young people will be left frustrated, seeing their university peers from more wealthy backgrounds excel only because parents' money was there to support them through the initial period of poverty wages. Those living in rural areas are further disadvantaged by lack of access to cities where most new jobs are located. Half of all young people now feel they will not achieve their goals. Research by the Prince's Trust reveals that one-quarter of all 16-25 year olds are regularly down or depressed. And depression does not help self-motivation, the very trait needed to seek out job opportunities.
