【单选题】

About three-quarters of Americans, according to surveys, think the country is on the wrong track. About two-thirds of the public disapprove of the job performance of President Bush, and an even higher number disdain Congress. The media are excited about the prospect of a wealthy businessman running for President as an independent who could tap into broad public disgruntlement with the partisan politicians in Washington.
2007 Yes. But also 1992. The main difference between the two situations is that Michael Bloomberg is richer—and saner—than Ross Perot. But one similarity might be this: the American people were wrong then and may be wrong now. The widespread pessimism in the early 1990s about the course of the country turned out to be unwarranted. The rest of the decade featured impressive economic growth, a falling crime rate, successful reform of the welfare system and a reasonably peaceful world. Perhaps the problems weren’t so bad in the first place, or perhaps the political system produced politicians, like Bill Clinton, Rudy Giuliani and Newt Gingrich, who were able to deal with the problems. But, in any case, the country got back on course. That’s not to say all was well in the 1990s, especially in foreign policy. Responsibilities in places ranging from Bosnia to Rwanda to Afghanistan were shirked, and gathering ers weren’t dealt with. Still, the sour complaints and dire predictions of 1992—oh, my God, the budget deficit will do us in! —were quickly overtaken by s. What’ s more, the fear of many conservatives that we might be at the mercy of unstoppable forces of social disintegration turned out to be wrong. Indeed, the dire predictions were rendered obsolete so quickly that one wonders whether we were, in 1992, really just indulging in some kind of post-cold-war victory. Sometimes the public mood is…well, moody.
Today we’re moody again. We are obviously fighting a difficult and, until recently, badly managed war in Iraq, whose outcome is uncertain. This accounts for much of the pessimism. It also doesn’t help that the political system seems incapable of dealing with big problems like immigration, an energy policy and health care. Still, is the general feeling that everything is going to the dogs any more justified today than it was 15 years ago
Not really. Think of it this way: Have s in general gone better or worse than most people would have predicted on Sept. 12, 2001 There’s been no successful second attack here ill the U. S. —and very limited terrorist successes in Europe or even in the Middle East. We’ve had 5 1/2 years of robust economic growth, low unemployment and a stock-market recovery. Social indicators in the U. S. are mostly stable or improving—abortions, age births and age drug use are down and education scores are up a bit.
As for American foreign policy since 9/11, it has not produced the results some of us hoped for, and there are many legitimate criticisms of the Bush Administration’s performance. But, in fact, despite the gloom and doom from critics left and right (including, occasionally, me), the world seems to present the usual mixed bag of difficult problems and heartening developments.
The key question, of course, is the fate of Iraq. A decent outcome—the defeat of al-Qaeda in what it has made the central front in the war on terrorism and enough security so there can be peaceful rule by a representative regime—seems to me achievable, if we don’ t lose our nerve here at home. With success in Iraq, progress elsewhere in the Middle East will be easier. The balance sheet is uncertain. But it is by no means necessarily grim.
The phrase "going to the dogs" (line 4, paragraph 3) most probably means

A.
becoming worse.
B.
becoming lazier.
C.
becoming crazier.
D.
becoming easier.

【单选题】The onset of a new generation of computer attacks was marked by () A. an organization of gangs B. the infection of PCs C. the sale of a software D. a website’s vanishing

A.
The "MyDoom" virus could presage a generation of computer attacks by organised gangs aiming to extract ransoms from online businesses, experts said yesterday.
B.
The warning came as the website run by SCO, a company that sells Unix computer software, in effect disappeared from the web under a blizzard of automated attacks from PCs infected by the virus, which first appeared a week ago.
C.
The "MyDoom-A" version of the virus is reckoned to be the worst to have hit the internet, in terms of the speed of its spread, with millions of PCs worldwide believed to be infected. Such "zombie" machines begin to send out hundreds of copies of the virus every hour to almost any e-mail address in their files.
D.
On Sunday they began sending automated queries to SCO’s website, an attack that will continue until 12 February. The attack is the web equivalent of ringing the company’s doorbell and running away a million times a second, leaving its computers unable to deal with standard requests to view its pages.
E.
"You have to wonder about the time limit," said Graham Cluley, senior technology consultant at the antivirus company Sophos. "Someone could go to SCO after the 12th and say, ’If you don’t want this to happen again, here are our demands’." Raimund Genes, European president of the security software firm Trend Micro, said: "Such a programme could take out any major website on the internet. It’s not terrorism, but it is somebody who is obviously upset with SCO"
F.
SCO has earned the enmity of computer users through a lawsuit it has filed against IBM. SCO claims ownership of computer code it says IBM put into the free operating system Linux, and is demanding licence fees and damages of $1bn.
G.
Mr. Cluley said: "It might be that whoever is behind this will say to SCO, ’if you don’t want the next one to target you, drop the lawsuit’." SCO has offered $250,000 (£140,000) for information leading to the arrest of the person or people who wrote and distributed MyDoom.
H.
Nell Barrett, of the security company Information Risk Management, said, "I would give a lot of credence to the idea of gangs using viruses to extort money. It’s hard for law enforcement to track them down, because they’re using machines owned by innocent people."
I.
A second variant of MyDoom will start attacking part of Microsoft’s website later today. The antivirus company MessageLabs said it had blocked more than 16 million copies of the virus in transit over the net so far. But millions more will have reached their targets.
