It would be all too easy to say that Facebook’s market meltdown is coming to an end.After all,Mark Zuckerberg’s social
network burned as much as$50 billion of shareholders’wealth in just a couple months.To put that in context,since its debut(初次登台)on NASDAQ in May,Facebook has lost value nearly equal to Yahoo,AOL,Zynga,Yelp,Pandora,Open Table,
Group on,LinkedIn,and Angie's List combined,plus that of the bulk of the publicly traded newspaper industry:
As shocking as this utter failure may be to the nearly 1 billion faithful Facebook users around the world,it’s no surprise to
anyone who read the initial public offering(IPO)prospectus(首次公开募股说明书).Worse still,all the crises that emerged
when the company debuted-overpriced shares,poor corporate governance,huge challenges to the core business,and a
damaged brand-remain today.Facebook looks like a prime example of what Wall Street calls a falling knife-that is,one that
can cost investors their fingers if they try to catch it.
Start with the valuation.To justify a stock price close to the lower end of the projected range in the IPO,say$28 a share,Facebook’s future growth would have needed to match that of Google seven years earlier.That would have required
increasing revenue by some 80 percent annually and maintaining high profit margins all the while.
That’s not happening.In the first half of 2012,Facebook reported revenue of$2.24 billion,up 38 percent from the same
period in 2011.At the same time,the company’s costs surged to$2.6 billion in the six-month period.
This so-so performance reflects the Achilles’heel of Facebook’s business model,which the company clearly stated in a
list of risk factors associated with its IPO:it hasn’t yet figured out how to advertise effectively on mobile devices,The number
of Facebook users accessing the site on their phones surged by 67 percent to 543 million in the last quarter,or more than
half its customer base.
Numbers are only part of the problem.The mounting pile of failure creates a negative feedback loop that threatens Facebook’s future in other ways.Indeed,the more Facebook’s disappointment in the market is catalogued,the worse Facebook’s
image becomes.Not only does that threaten to rub off on users,it’s bad for recruitment and retention of talented hackers,who are the lifeblood of Zuckerberg’s creation.
Yet the brilliant CEO can ignore the sadness and complaints of his shareholders thanks to the super-voting stock he
holds.This arrangement also was fully disclosed at the time of the offering.It’s a pity so few investors apparently bothered to
do their homework.


What can be inferred about Facebook from the first paragraph 《》（）

A.Its market meltdown has been easily halted.
B.It has increased trade with the newspaper industry.
C.It has encountered utter failure since its stock debut.
D.Its shareholders have invested$50 billion in a social network.

资料：Singapore Airlines plans to introduce inflight mobile phone and internet access in May this year,beginning with its flagship Airbus A380 fleet.
Several pricing models are believed to be under consideration,beginning with a low-cost package suitable for WE—service such as Google Gmail,Yahoo and Hotmail as well as a 30MB allowance for around SGD$25 （that's $20 Russia and US,and ￡20 and ￡ 14）.
The airline is polling selected members of its KrisFlyer frequent flyer loyalty program to participate in an online survey about your attitudes towards inflight mobile and internet services,which we are planning to introduce from May 2011 according to the email invitation.
The survey asks travellers for their opinions on pricing packages such as SGD$25 for 30MB,as well as if mobile phone cells and SMS messages should be permitted.
Should passagers be allowed to make and take calls at 30000 feet they'll pay plenty for the privilege, with calls being charged at international roaming rates.
As it's up to each country to decide what those rates are-and with Singapore Airlines effectively being its own country in terms of providing a fully controlled and self-contained telecoms system on board each plane-those rates could literally be sky high.
SQ's inflight internet and mobile service, which may carry the KrisNet brand in keeping with the KrisWorld inflight entertainment system, is expected to debut on the Airbus A380 before being installed onto the airline's A340-500 and Boeing 777-300ER aircraft.
Passagers will be able to access the internet on any device from a smart phone to a tablet or laptop, as Singapore Airlines will support connections through both Wifi wireless networking （using a series of low-hotpots located throughout the plane） and 3G（via tiny pico-cell stations）.
It will employ the pepular OnAir technology, jointly developed by IT company SITA and Airbus,and currently used by over 20 airlines（including Air New Zealand's current
trial of in-flight internet） which feeds the Wifi and 3G signals through to Inmarsat's SwiftBroadband satellite network.

Which of the following may be the best title for the passage?

A.Singapore Airlines to charge high international roaming rates
B.Singapore Airlines to offer different pricing models for inflight mobile and Internet services
C.Singapore Airlines to unveil sky high net
D.Singapore Airlines to conduct online survey
