单选题One Good Reason to Let Smallpox Live It's now a fair bet that we will never see the total extinction of the smallpox virus. The idea was to cap the glorious achievement of 1980, when smallpox was eradicated in the wild, by destroying the killer virus in the last two labs that are supposed to have it — one in the US and one in Russia. If smallpox had truly gone from the planet, what point Was there in keeping these reserves? (1) reality, of course, it was naive to (2) that everyone would let (3) of such a potent potential weapon.

单选题In the late 1960s and early 1970s, New York legislators faced a drug problem they feared was growing out of control. Federal statistics showed as many as 559,000 users nationwide and state police saw a 31 percent increase in drug arrests by 1972. In response Gov. Nelson Rockefeller created the Narcotic Addiction and Control Commission in 1967, aimed at helping addicts get clean. After the program proved too costly and ineffective. New York launched the Methadone(美沙酮) Maintenance Program, which similarly caused little reduction in drug use. But by 1973, calls for stricter penalties had grown too loud to ignore, prompting Albany to pass legislation that created required minimum sentences of 15 years to life for possession of four ounces of narcotics—about the same as a sentence for second -degree murder. What was troubling New York in late 1960s and early 1970s according to the passage?A. There were 559,000 drug users in the state.B. There was a 31% increase in drug use by 1972.C.

单选题Is the Internet Broken? Google's Gmail system, which serves millions of customers around the world, shut down yesterday. Twitter, the micro - blogging service used by tens of millions of people, went off - line last month. It blamed the trouble on a malicious programmer in Russia who was trying to shut down the account of a user in neighboring Georgia. It is astonishing the local actions of a small number of programmers can bring an entire Interact service to its knees, but that have been the case. The Internet as it is set up now operates at three levels. The first is the servers that store data and content for use by customers. Google and other large companies keep massive server farms. These are well -protected from outside programmers by sophisticated software, but clearly that does not always work. The protection devices may fail more and more often as hackers get more skillful. The second part of the Internet is the" pipes" that carry data, video, e - mail messages, and text of websites from companies such as Google, Yahoo !, and Twitter, that make up Internet content and services to customers. Some of these" pipe" providers, specifically telecom and cable companies, are already complaining that the amount of data that they have to move is rising too rapidly for them to accommodate. Video files, which aye particularly large, have posed significant problems to cable companies. The last piece of the Internet is the end user, the companies and consumers who have the PCs. Perversely, these PCs are also the tools by which hackers build malicious code that they send out to compromise the effectiveness of the servers to destroy the data transport system which is at the core of the worldwide web's operations. The problem of online outages is as old as the internet itself, AOL's dial - up 56k service would go down regularly in the mid - 1990s. The company did not have enough modems to keep up with demand. The Internet for the last decade may not be the Internet for the future. The prophylactic software that was meant to protect the web is less effective. Like anything else that is used regularly whether it is a car, a light bulb, or a PC, the Internet is going to have to be upgraded more often now. It won't work every hour of every day anymore.

单选题Northern Europeans are willing to pay a lot of money and put up with a lot of inconveniences for the sun because they have so little of it. Residents of cities like London, Copenhagen, and Amsterdam spend a lot of their winter in the dark because the days are so short, and much of the rest of the year is in the rain.

单选题On Sleep Baekeland and Hartmann report that the "short sleepers" had been more or less average in their sleep needs until the men were in their teens. But at about age 15 or so, the men voluntarily began cutting down their nightly sleep time because of pressures from school, work, and other activities. These men tended to view their nightly periods of unconsciousness as bothersome interruptions in their daily routines. In general, these "short sleepers" appeared ambitious, active, energetic, cheerful, conformist (不动摇) in their opinions, and very sure about their career choices. They often held several jobs at once, or workers full or part-time while going to school. And many of them had a strong urge to appear "normal" or "acceptable" to their friends and associates. When asked to recall their dreams, the "short sleepers" did poorly. More than this, they seemed to prefer not remembering. In similar fashion, their usual way of dealing with psychological problems was to deny that the problem existed, and then to keep busy in the hope that the trouble would go away. The sleep patterns of the "short sleepers" were similar to, but less extreme than, sleep patterns shown by many mental patients categorized as manic (疯人). The "long sleepers" were quite different indeed. Baekeland and Hartmann report that these young men had been lengthy sleeps since childhood. They seemed to enjoy their sleep, protected it, and were quite concerned when they were occasionally deprived of their desired 9 hours of nightly bed rest. They tended to recall their dreams much better than did the "short sleepers". Many of the "long sleepers" were shy, anxious, introverted (内向), inhibited (压抑), passive, mildly depressed, and unsure of themselves (particularly in social situations). Several openly states that sleep was an escape from their daily problems.
