[不定项选择题]If you have got kids, here is a nasty truth: they are probably not very special, that is, they are average, ordinary, and unremarkable. Consider the numbers of those applications your daughter is sending to Ivy League schools, for instance. There are more than a quarter of a million other kids aiming for the same eight colleges at the same time, and less than 9% of them will make the cut. And those hours you spend coaching Little League because you just know your son's sweet swing will take him to the professionals. There are 2.4 million other Little Leaguers out there, and there are exactly 750 openings for major league ballplayers at the beginning of each season. That gives him a 0.0313% chance of reaching the big clubs. The odds are just as long for the other dreams you've had for your kids: your child the billionaire, the Broadway star, the Rhodes scholar. Most of those things are never going to happen.The kids are paying the price for parents' delusions. In public schools, some students are bringing home 17.5 hours of homework per week or 3.5 per school night and it's hard to see how they have time to do it. From 2004 to 2014, the number of children participating in up to three hours of aider-school activities on any given day rose from 6.5 million to 10.2 million. And all the while, the kids are being fed a promise--that they can be tutored and coached, pushed and tested, hot- housed and advance placed until success is assured. At last, a growing chorus of educators and psychologists is saying, "Enough!" Somewhere between the self-esteem building of going for the gold and the self-esteem crushing of the Ivy-or-die ethos there has to be a place where kids can breathe, where they can have the freedom to do what they love and where parents accustomed to pushing their children to excel can shake off the newly defined shame of having raised an ordinary child.
If the system is going to be fixed, it has to start, no surprise, with the parents. For them, the problem isn't merely the expense of the tutors, the chore of the homework checking and the constant search for just the right summer program. It's also the sweat equity that comes from agonizing over every exam, grieving over every disappointing grade--becoming less a guide in a child's academic career than an intimate fellow traveler.
The first step for parents is accepting that they have less control over their children's education than they think they do--a reality that can be both sobering and liberating. You can sign your kids up for ballet camp or violin immersion all you want, but if they're simply doing what they're told instead of doing what they love, they'll take it only so far.
Ultimately, there's a much larger national conversation that needs to be had about just what higher education means and when it's needed at all. Four years of college has been sold as being a golden ticket in the American economy, and to an extent that's true. But pushing all kids down the bachelor's path ensures not only that some of them will lose their way
but also that critical jobs that require a two-year or less--skilled trades, some kinds of nursing, computer technology, airline mechanics and more--will go unfilled.
There will never be a case to be made for a culture of academic complacency or the demolition of the meritocracy. It can be fulfilling for kids to chase a ribbon, as long as it's a ribbon the child really wants. And the very act of making that effort can bring out the best in anyone's work.
But we cheat ourselves, and worse, we cheat our kids, if we view life as a single straight-line race in which one one-hundredth of the competitors finish in the money and everyone else loses.We will all be better off if we recognize that there are a great many races of varying lengths and outcomes. The challenge for parents is to help their children find the one that's right for them.
Which of the following factors deprives the kids of freedom to do what they love?
A. 3.5 hours of school assignments set by their teachers every day.
B. The educational reforms made by the public schools they atten
D.
A.
B.The growing number of peers taking part in off-campus activities.

近几年,通信技术网络的超高速化,已成为世界上的发展潮流。空间技术与计算机融合成跨越时间与空间的信息基础结构,它将逐渐深入千家万户,从根本上改变人们的生产、生活和相互交往的方式,加速人类文明和文化的传播,增进相互理解和全球意识。
空间信息高速公路,这一名词是借鉴信息高速公路概念,也是信息高速公路的拓宽与延伸。所谓空间信息高速公路,我们可以形象地将它理解为以卫星、光纤再辅之以其他通信手段作为“公路”,而以集电脑、电话、电视、传真等为一体的多媒体作为“汽车”,使信息高速传递并能共享的通信网络。这种网络遍布全国乃至全球。在我国则将它称之为国家经济信息化基础设施,其内涵包括4项要素:网络与通信、计算机与信息化设备、信息资源与服务、人与信息化环境。
卫星通信和数字网络光缆就像高速公路一样,是促进社会经济发展的基础设施。它不仅是地面光缆数字通信网络系统,而且还包括通信卫星,卫星定位系统和环境、灾害监测技术系统。此外,还有不断更新的社会、经济统计数据库和自然资源数据系列,以及宏观调控、规划决策和工程设计服务及知识库,逻辑推理机等人工专家系统,这样,才能有效地实现以信息交流代替人流。物流与能量流。
加速发展空间技术,多方面、高效率地利用空间技术,特别是充分利用空间信息资源,促进社会生产力的发展,已成为当今世界的共识。通信卫星具有通信容量___________、可靠性___________、传输距离___________、不受地理环境影响等许多优点,所以备受各国的重视和欢迎。在空间信息高速公路中,卫星无线电信频率宽,极容易实现双向高速率的数据和可视电信业务。并适用于单相多路的电视节目以及新闻报道,对大多数用户都有实用价值。对发展中国家来说,空间信息高速公路的建设,可弥补通信基础设施差与区域性通信空缺之不足。例如,地面信息高速公路的成本昂贵,需要10~15年甚至更长时间才能建成,是一个无法在短期内普及服务的巨额投资项目,而卫星接收设备费用大约只需200美元,其技术是现成的,是一个在短期内便能普及并能满足绝大多数用户需求的业务项目。

A. 通信技术网络怎样超高速化
B. 空间信息高速公路
C. 卫星通信和数字网络光缆
D. 卫星通信和数字网络光缆的超高速化
