单选题The computer network is a creation of the electronic age. In a computer system, a hacker is worse than a thief entering your house. He could go through anyone's electronic mail or add to, change, distort or delete anything in the information stored in the computer's memory. He could even take control of the entire system by inputting his own instructions in the software. He could shut the computer down whenever he wished, and no one could stop him. Then he could program the computer to erase any sign of his ever having been there. Hacking, our electronic-age term for computer break-in, is more and more in the news: A dissatisfied former insurance-company employee wipes out information from payroll files. A student sends out a "virus", a secret and destructive command, over a national network. The virus copies itself at lighting speed, jamming the entire network--thousands of commercial and government computer systems. Now exists the possibility of terrorism by computer. Destroying a system responsible for air-traffic control at a busy airport or the telephones of a major city is a relatively easy way to spread alarm. Yet neither business nor government has done enough to strengthen its defenses against attack. For one thing, such defenses are expensive; for another, they may interrupt communication--the main reason for using computers in the first place.

单选题Women's fashions tend to change more rapidly than men's. In the early 1900s all women wore their skirts down to the ankle. Today, skirt length varies from floor- length to ten inches above the knee. Women's shoes have also gone through all sorts of changes in the last ninety years. For instance, boots for women were very common at the beginning of this century. Then, for a few years, they were not considered fashionable. Today they are back in style again in all colors, lengths, and materials. In fact, today's women can wear all types of clothes, even T-shirts and shorts on almost any occasion. While all of these changes were taking place in women's fashions, men's clothing remained pretty much the same until a couple of years ago. And, in fact, most men still wear the traditional suit, jacket, shirt, tie, though bright colors, patterns, and a variety in cut are now more common.

单选题According to the Wharton Center for Applied Research in the US, professionals (专业人员) spend an average of 23 hours a week in meetings. But they consider only 58% of that time worthwhile. It doesn't have to be this way. Here is some advice for you to use meetings to advance your career, not eat up your productivity (工作效率): 1)Know what you want. Know precisely why the meeting is being held and decide what you intend to accomplish. If you cannot write these two things down, the meeting should not take place. 2) Figure out if a face-to-face meeting is necessary. Would a group email be sufficient? Or a couple of phone calls? These ways would probably be more efficient with colleagues you know. well. 3) Pick the right times. If possible, avoid arranging meetings during your peak productive hours. 4) Be prepared. If there are documents to be discussed, hand them out to participants the day before. 5) Set aside a certain amount of time each week for meetings, and stick to it. The truth is most people want to leave. They are just suffering from what some experts call the "politeness disease".
