单选题In department stores and closets all over the world, they are waiting. Their outward appearance seems rather appealing because they come in a variety of styles, textures, and colors. But they are ultimately the biggest deception that exists in the fashion industry today. What are they? They are high heels—a woman"s worst enemy (whether she knows it or not). High heel shoes are the downfall of modern society. Fashion myths have led women to believe that they are more beautiful or sophisticated for wearing heels, but in reality, heels succeed in posing short as well as long term hardships. Women should fight the high heel industry by refusing to use or purchase them in order to save the world from unnecessary physical and psychological suffering. For the sake of fairness, it must be noted that there is a positive side to high heels. First, heels are excellent for aerating (使通气,) lawns. Anyone who has ever worn heels on grass knows what I am talking about. A simple trip around the yard in a pair of those babies eliminates all need to call for a lawn care specialist, and provides the perfect-sized holes to give any lawn oxygen without all those messy chunks of dirt lying around. Second, heels are quite functional for defense against oncoming enemies, who can easily be scared away by threatening them with a pair of these sharp, deadly fashion accessories. Regardless of such practical uses for heels, the fact remains that wearing high heels is harmful to one"s physical health. Talk to any podiatrist (足病医生)， and you will hear that the majority of their business comes from high-heel-wearing women. High heels are known to cause problems such as deformed feet and torn toenails. The risk of severe back problems and twisted or broken ankles is three times higher for a flat shoe wearer. Wearing heels also creates the threat of getting a heel caught in a sidewalk crack or a sewer grate (阴沟栅) and being thrown to the ground—possibly breaking a nose, back, or neck. And of course, after wearing heels for a day, any woman knows she can look forward to a night of pain as she tries to comfort her swollen, aching feet. (384 words)

单选题Can computer viruses ever be a force for progress? In the wild west of the online world, the archetypal baddies are computer viruses and worms. These self-replicating programs are notorious for wreaking havoc in the systems of unwary users. But, as in the west, not all gunslingers wear black hats. Some virus writers wish their fellow users well, and have been spreading viruses that are designed to do good, not harm. Cheese Worm, which appeared a few weeks ago, attempts to fix computers that have been compromised by the Lion Worm. The Lion Worm is dangerous. It infects computers that use the Linux operating system, and creates multiple "backdoors" into the infected computer. It then e-mails information about these backdoors to people who wish to misuse that computer for nefarious purposes such as "denial of service" attacks on websites. (Such attacks bombard a site with so many simultaneous requests for access that it comes out with its hands up.) That might sound like a good thing. So might VBS. Noped. A @ mm. This virus, which arrives as an e-mail attachment, searches a user's hard drive for specific files which the (unknown) virus writer believes contain child pornography. If the virus finds any files on the proscribed list, it e-mails a copy of the file in question to a random recipient from a list of American government agencies, with an explanatory note. The notion of "good" viruses may sound novel; but, according to Vesselin Bontchev, a virus expert with Frisk Software International in Iceland, it is not. However, early attempts to create beneficial viruses—for example, programs that compressed or encrypted files without asking a user's permission—were resented, because they represented a loss of control over a user's computer, and a diversion of data-processing resources. Inoculating computers against infection sounds like a good idea, but fails because any unauthorised changes are suspicious. Cheese Worm, even though it is designed to help the user whose disk it ends up on, suffers from the same objection. And VBS. Noped. A @ mm, whatever social benefits its author might think it has, is not even meant to do that. If it works, it will harm the user rather than help him. It is little more than cyber-vigilantism. Appropriate to the wild west, perhaps, but if cyberspace is to be civilised, other solutions will have to be found.
