冉氏烹狗记(片断)

县人冉氏,有狗而猛,遇行人,辄搏噬(shì)之,往往为所伤,伤则主人躬诣谢罪,出财救疗之,如是者数矣。冉氏以是颇患苦狗;然以其猛也,未忍杀,故置之。

刘位东谓余曰:“余尝夜归,去家门里许,群狗狺狺①吠,冉氏狗亦迎而吠焉。余以柳枝横扫之,群狗皆远立,独冉氏狗竟前欲相搏。几(jī)伤者数矣。余且斗且行,过冉氏门而东,且数十武②,狗乃止。当是时,身惫甚,幸狗渐远。憩道旁,良久始去,狗犹望而吠也。既归,念此良狗也,藉令③有仇盗夜往劫之,狗拒门而噬,虽数人能入咫尺地哉!闻冉氏颇患苦此狗,旦④若遇之于市,必嘱之使勿杀;此狗累千金不可得也。居数日,冉氏之邻至,问其狗,曰:‘烹之矣。’惊而诘其故,曰:‘日者冉氏有盗,主人觉之,呼二子起,操械共逐之,盗惊而遁⑤。主人疑狗之不吠也,呼之不应。遍索之,无有也。将寝,闻卧床下,若有微息⑥者,烛之,则狗也,卷屈蹲伏,不敢少转侧,垂头闭目,若惟恐人之闻其声息者。’主人曰:‘嘻!吾向之隐忍而不之杀者,为其有仓卒一旦⑦之用也,恶⑧知其搏行人则勇,而见盗则怯乎哉?以是故,遂烹之也。’”

嗟乎!天下之勇于搏人而怯于见贼者,岂独此狗也哉?

[注:①狺狺(yin),狗叫声。②且,将近;武,古代以半步为武。③藉(jiè)令,假使。④旦,明早,⑤遁(dù),逃走。⑥微息,细微的喘气声。⑦仓卒(cù),勿忙;一旦,一时。⑧恶(wū),怎。]

题型:单项选择题

The economy may be troubled, but one area is thriving: social media. They begin with Facebook and extend through a dizzying array of companies that barely existed five years ago: Twitter, LinkedIn, Groupon, Yammer, Yelp, Flickr, Ning, Digg--and the list goes on. These companies are mostly private but have attracted the ardent attention of Wall Street and investors, with Facebook now worth a purported $ 75 billion and Groupon valued at close to $ 25 billion.
There can be little doubt that these companies enrich their founders as well as some investors. But do they add anything to overall economic activity While jobs in social media are growing fast, there were only about 21,000 listings last spring, a tiny fraction of the 150 million-member U. S. workforce. So do social-media tools enhance productivity or help us bridge the wealth divide Or are they simply social--entertaining and diverting us but a wash when it comes to national economic health
The answers are vital, because billions of dollars in investment capital are being spent on these ventures, and if we are to have a productive future economy, that capital needs to grow the economic pie~and not just among the elite of Silicon Valley and Wall Street. The U. S. retains a competitive advantage because of its ability to innovate, but if that innovation creates services that don’t turn into jobs, growth and prosperity, then it does us only marginal good.
The problem is that these tools are so new that it is extremely difficult to answer the questions definitively. As I was about to write this column, I overheard a ceil-phone conversation at an airport with this snippet.- "The company says they are using social media, but who knows if it is making any difference" Flash back nearly 20 years and the same question was being asked about the first Internet wave. Were Netscape and the Web enhancing our economy, or were people just spending more time at work checking out ESPN. com Official statistics weren’t designed to capture the benefits, and didn’t--until statistics mavens at the Federal Reserve, urged on by Alan Greenspan, refined the way they measured productivity. As a result of these somewhat controversial innovations, the late 1990s became a period of substantial technology-driven gains.
It is possible that the same gap exists today, that social-media tools are indeed laying the groundwork for new industries and jobs but aren’t yet registering on the statistical radar. Many companies believe social media make them more competitive. Ford and Zappos, for instance, use Twitter to market their products and address consumer complaints. Countless corporations have created internal Face-book pages and Yammer accounts for employees to communicate across divisions and regions. Industry groups for engineers, doctors and human-resources professionals have done the same to share new ideas and solutions on a constant basis rather than episodically at conferences. Staffing companies have been especially keen on social media; a senior executive at Manpower told me we should think of social-media tools as today’s version of the telephone. Yes, they are used for frivolity and all sorts of noneconomic activity (chatting with friends, passing the time), but they also help communication happen more efficiently.
One big question is what proportion of that benefit will be captured economically by consumers vs. corporations. Sure, social media allow people to compare prices and quality and assess which companies are good to work for and where jobs might be. They also may enhance education and idea sharing, but the caveat is that the people who use these tools are the ones with higher education and income to spend on technology, not the tens of millions whose position in today’s world has eroded so sharply. According to a recent Pew Foundation study, only 45% of adults making less than $ 30,000 have access to broadband, which is an essential component of using content-rich social media effectively.
And that is the tub. Like so many things these days, social media contribute to economic bifurcation. Dynamic companies are benefiting from these tools, even if the gains are tough to nail down in specific figures. Many individuals are benefiting too, using LinkedIn to find jobs and Groupon to find deals. But for now, the irony is that social media widen the social divide, making it even harder for the have-nots to navigate. They allow those with jobs to do them more effectively and companies that are profiting to profit more. But so far, they have done little to aid those who are being left behind. They are, in short, business as usual.

When the author says that ’"social media tools.., aren’t registering on the statistical radar" (para. 5), he means that______.

A. they are not expected to greatly enhance productivity
B. they do not lay the groundwork for the establishment of new jobs
C. the statistical data do not reflect the efficiency social media tools have brought
D. the statistical data do not show the expected cost in using social media tools
