Section C56、回答56-61题：
Global warming may or may not be the great enviromental crisis of the 21st century, but---regardless ofwhether it is or isn't--we won't do much about it. We will argue over it and may even, as a nation, make somefairly solemn-sounding commitments to avoid it. But the more dramatic and meaningful these commitments seem,the less likely they are to be observed.
AI Gore calls giobal warming an "inconvenient truth," as if merely recognizing it could put us on a path to asolution. But the real truth is that we don't know enough to relieve global warming, and--without majortechnological
breakthroughs--we can't do much about it.
From 2003 to 2050, the world's population is projected to grow from 6.4 billion to 9.1 billion, a 42% increase.If energy use per person and technology remain the same, total energy use and greenhouse gas emissions(mainly CO2) will be 42% higher in 2050. But that's too low, because societies that grow richer use more energy.
We need economic growth unless we condemn the world's poor to their present poverty and freeze everyone else'sliving standards. With modest growth, energy use and greenhouse emissions more than double by 2050.
No government will adopt rigid restrictions on economic growth and personal freedom (limits on electricityusage, driving and travel) that might cut back global warming. Still, politicians want to show they're "doingsomething." Consider the Kyoto Protocol( 《京都议定书》). It allowed countries that joined to punish those thatdidn't. But it hasn't reduced CO2 emissions (up about 25% since 1990), and many signatories (签字国) didn'tadopt tough enough policies to hit their 2008-2012 targets.
The practical conclusion is that if global warming is a potential disaster, the only solution is new technology.Only an aggressive research and development program might find ways of breaking our dependence on fossil fuelsor dealing with it.
The trouble with the global warming debate is that it has become a moral problem when it's really an engineering one. The inconvenient truth is that if we don't solve the engineering problem, we're helpless.

61、Questions{TSE}are based on the following passage.
Someday a stranger will read your e-mail without your permission or scan the Websites you've visited. Orperhaps someone will casually glance through your credit card purchases or cell phone bills to find out yourshopping preferences or calling habits.
In fact, it's likely some of these things have already happened to you. Who would watch you without yourpermission? It might be a spouse, a girlfriend, a marketing company, a boss, a cop or a criminal. Whoever it is, theywill see you in a way you never intended to be seen--the 21st century equivalent of being caught naked.
Psychologists tell us boundaries are healthy, that it's important to reveal yourself to friends, family and loversin stages, at appropriate times. But few boundaries remain. The digital bread crumbs (碎屑) you leave everywhere make it easy for strangers to reconstruct who you are, where you are and what you like. In somecases, a simple Google search can reveal what you think. Like it or not, increasingly we live in a world where yousimply cannot keep a secret.
The key question is: Does that matter?
For many Americans, the answer apparently is "no."
When opinion polls ask Americans about privacy, most say they are concerned about losing it. A survey foundan overwhelming pessimism about privacy, with 60 percent of respondents saying they feel their privacy is"slipping away, and that bothers me."
But people say one thing and do another. Only a tiny fraction of Americans change any behaviors in an effortto preserve their privacy. Few people turn down a discount at tollbooths (收费站) to avoid using the EZ-Pass system that can track automobile movements. And few turn down supermarket loyalty cards. Privacyeconomist Alessandro Acquisti has run a series of tests that reveal people will surrender personal information likeSocial Security numbers just to get their hands on a pitiful 50-cents-offcoupon(优惠劵).
But privacy does matter--at least sometimes. It's like health: When you have it, you don't notice it. Only when
it's gone do you wish you'd done more to protect it.

63、Why does the author say "we live in a world where you simply cannot keep a secret" ( Line 5, Para.3)?
A．Modem society has finally evolved into an open society.
B．People leave traces around when using modem technology.
C．There are always people who are curious about others' affairs.
