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

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

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.

There’s no doubt that nanotechnology promises so much for civilization. However, all new technologies have their teething problems, And with nanotechnology, society often gets the wrong idea about its capabilities. Numerous science-fiction books and movies have raised people’s fears about nanotechnology ---with scenarios such as inserting little nano-robots into your body that monitor everything you do without you realizing it,or self-replicating nano-robots that eventually take over the world.
So how do we safeguard such a potentially powerful technology? Some scientists recommend that nano-particles be treated as new chemicals with separate safety tests and clear labelling. They believe that greater care should also be taken with nano-particles in laboratories and factories. Others have called for a withdrawal of new nano products such as cosmetics and a temporary halt to many kinds of nanotech research.
But as far as I’m concerned there’s a need to plough ahead with the discoveries and applications of nanotechnology.I really believe that most scientists would welcome a way to guard against unethical uses of such technology. We can’t go around thinking that all innovation is bad.all advancement is bad. As with the debate about any new technology.it is how you use it that’s important.So let’s look at some of its possible uses.
Thanks to nanotechnology, there could be a major breakthrough in the field of transportation with the production of more durable metals. These could be virtually unbreakable, lighter and much more pliable leading to planes that are 50 times lighter than at present. Those same improved capabilities will dramatically reduce the cost of traveling into space making it more accessible to ordinary people and opening up a totally new holiday destination.
In terms of technology, the computer industry will be able to shrink computer parts down to minute sizes. We need nanotechnology in order to create a new generation of computers that will work even faster and will have a million times more memory but will be about the size of a sugar cube. Nanotechnology could also revolutionise the way that we generate power .The cost of solar cells will be drastically reduced so harnessing this energy will be far more economical than at present.
In the author’s opinion, research into nanotechnology probably means that it_A. has yet to win popular support
B. ought to be continued
C. could be seen as unethical
D. can replicate people completely

The colourful chalkboards and baskets of fruit that greet customers at the entrances of Whole Foods Market's shops paint a rosy picture.Yet shares in the American seller of organic and natural food have fallen by more than 40%since hitting a peak last October,in a period when stock markets have been strong.
It is not that the retailer is in immediate crisis:its latest quarterly figures,on July 30th heowed sales and profits both up a bit.And it is not that people are going off the idea of paying more for food produced without chemical fertilisers,pesticides or additives:the International Federation of Organic Agriculture Movements reckons that the industry's worldwide revenues were a record of 63 billion in 2012;and Techsci Research,a market-research firm,predicts that the American market for such foods-the worlds largest-may grow by 14%by 2018.
The problem is that at Whole Foods,shoppers have been paying way over the cost of regular produce,and its success in getting them to do so has now attracted a lot of competitors,from rival organics chains like Sprouts and Trader Joe's to mass-market retailers like Walmart and Costco.As a result,the price premium for organic produce is crashing down.On a recent shopping trip,a pound of organic apples cost 2.99 at Whole Foods but just 1.99 at Sprouts and even less at Costco.
The firm has been trimming costs to keep its margins up,but the slump in its share price reflects investors expectation that this cannot continue,that profits will suffer and that Whole Foods'dominance of the market is coming to an end.
That the company has had to recall a number of products—in late July it and other grocers recalled plums and peaches suspected of contamination with Listeria bacteria—has made it harder to maintain an air of superiority over its competitors.Organic foods'claim to superiority is questionable anyway.Both Britain's Food Standards Agency and the Annals of Internal Medicine,a journal,concluded after reviewing the extensive studies on the issue that there is no substantial difference in the nutritiousness of organics and non-organics.In some respects organics may be bad for the environment,because growing them uses land less efficiently than non-organics.
As for“natural”foods,there is no official definition of this,inAmericaat least;so the label,which Whole Foods also applies to many products,is close to meaningless.Alan McHughen,a botanist at the University of California,Riverside,argues that the whole industry is 99%marketing and public perception,reeling people in through a fabricated conceptof a time when food,and life in general,was simple and wholesome.
If true,the trick has worked nicely for Whole Foods.But its success has attracted so many imitators that it is losing its uniqueness Even recent speculation about a takeover bid has failed to lift its shares.It may insist its food is sustainable But it seems its prices are not.下列哪一选项与划线部分所表达意思相同A.Crisis Seems Far
B.The Firm Is at Risk
C.More Rivals Join In
D.Natural Foods Are Unreal
E.Stop Buying Organic Foods
F.The Recall Makes Things Worse
G.Traditional Foods Face Challenge

The colourful chalkboards and baskets of fruit that greet customers at the entrances of Whole Foods Market's shops paint a rosy picture.Yet shares in the American seUer of organic and natural food have fallen by more than 40%since hitting a peak last October,in a period when stock markets have been strong.41.It is not that the retailer is in immediate crisis:its latest quarterly figures,on July 30th,showed sales and profits both up a bit.And it is not that people are going off the idea of paying more for food produced without chemical fertilisers,pesticides or additives:the Intemational Federation of Organic Agriculture Movements reckons that the industry's worldwide revenues were a record of 63 biUion in 2012;and Techsci Research,a market-research firm,predicts that the American market for such foods-the world's largest-may grow by 14%by 2018.42.The problem is that at Whole Foods,shoppers have been paying way over the cost of regular produce,and its success in getting them to do so has now attracted a lot of competitors,from rival organics chains like Sprouts and Trader Joe's to mass-market retailers like Walmart and Costco.As a result,the pnce premium for organic produce is crashing down.On a recent shopping trip,a pound of organic apples cost 2.99 at Wbole Foods but just l.99 at Sprouts and even less at Costco.43.The firm has been trimming costs to keep its margins up,but the slump in its share price reflects investors'expectation that this cannot continue,that profits will suffer and that Whole Foods'dominance of the market is coming to an end.44.That the company has had to recall a number of products-in late July it and other grocers recalled plums and peaches suspected of contanunation with Listeria bacteria-has made it harder to maintain an air of superiority over its competitors.Organic foods'claim to superiority is questionable anyway.Both Britain's Food Standards Agency and the Annals of Internal Medicine,a journal,concluded after reviewing the extensive studies on the issue that there is no substantial difference in the nutriliousness of organics and non-organics.In some respects organics may be bad for the environment,because growing them uses land less efficiendy than non-organics.45.As for"natural"foods,there is no official definition of this,in America at least;so the label,which Whole Foods also applies to many products,is close to meaningless.Alan McHughen,a bota-nist at the University of California,Riverside,argues that the whole industry is"99%marketing;and public perception,"reeling people in through a fabricated concept of a time when food,and life in general,was simple and wholesome.If true,the trick has worked nicely for Whole Foods.But its success has attracted so many imitators that it is losing its uniqueness.Even recent speculation about a takeover bid has failed to lift its shares.It may insist its food is sustainable.But it seem8 its prices are not.43选？A.Crisis Seems Far

Text 2 Far from joining the labour force,women have been falling away at an alarming pace.The female employment rate in India,counting both the formal and informal economy,has tumbled from an already-low 35%in 2005 to just 26%now.Yet nearly 1Om fewer women are in jobs.A rise in female employment rates to the male level would provide India with an extra 235m workers,more than the EU has of either gender,and more than enough to fill all the factories in the rest ofAsia.Imagine the repercussions.Were India to rebalance its workforce in this way,the IMF estimates,the world's biggest democracy would be 27%richer.Its people would be well on their way to middle-income status.Beyond the obvious economic benelits are the incalculable human ones.Women who work are likelier to invest more in their children's upbringing,and to have more say over how they lead their lives.Social mores are startlingly conservative.A girl's first task is to persuade her own family that she should have a job.The in-laws she will typically move in with after marriage are even more likely to yank her out of the workforce and into social isolation.In a survey in 2012,84%of Indians agreed that men have more right to work than women when jobs are scarce.Men have taken 90%of the 36m additional jobs in industry India has created since 2005.And those who say that women themselves prefer not to work must contend with plenty of counter-evidence.Census data suggest that a third of stay-at-home women would WOfk ifjobs were available;govemment make-work schemes attract more women than men.What can be done?Many of the standard answers fall short.Promoting education,a time-tested development strategy,may not succeed.Figures show that the more schooling an Indian woman receives,the less likely she is to work,at least if she has anything less than a university degree.Likewise urbanization,another familiar way to alleviate poverty:city-dwelling women are half as likely as rural ones to have a job.An optimist might argue that more women are not working because India is still paying for the sins of the past,when so many of them were illiterate and high fertility rates bound them to the home.Most measures of female welfare are improving.India has many more girls in classrooms and fewer child brides than it once did.In fact,many fear that all that extra schooling was a parental ploy to improve a daughter's prospects not in the labour market but in the arranged-marriage market,part of the all-important quest to snag a suitable boy.A further push is needed to get Indian women what they really need:a suitable job.Once India balanced its workforce again,it would probably bring the following benefits except____.A.a wealthier India
B.a higher living standard
C.a brighter future for children
D.a heavy investment in education

单选题An electrical appliance company has submitted a new model of washing machine for stress and durability testing. After the conventional round of tests, 26 of the 90 machines tested no longer functioned. Observing these results, the company determined that the washing machine model was acceptable for the consumer market. Which of the following, if true, most strongly supports the company’s decision regarding the washing machine?A
When the number one rated washing machine was submitted for stress and durability testing, 96 out of 100 machines were still functioning at the end of the test.B
Because of the extreme stress of the testing process, any model that has more than two-thirds of its machines functioning at the end of the test process is considered sufficiently durable for the consumer market.C
Most consumers will tolerate a washing machine that functions only 64 times out of 90 attempts.D
Although the model tested is less durable than other models on the market, its projected price is considerably lower than that of the most durable models.E
The electrical failure that brought down most of the 26 washing machines that ceased functioning could probably be avoided if the machine were redesigned.
