单选题A new poll shows that people believe that computers and the Internet have made life better for Americans, but people also see some dangers in the trend toward computerization. The poll found that the public favors some government protection from cyber-problems (网络问题), but in general people are not especially concerned about issues such as information overload or the never-ending flow of phone calls, faxes and e-mails. A separate survey of children aged 10-17 shows that they have a more positive attitude about computers than adults do, and most have made use of up-to-dale technology in their schools. The survey found that enthusiasm for computers and the Internet is found in all income groups, all regions of the country, all races, and most age groups. However, people over 60 and those towards the lower end of the income rank tend to show lower rates of computer ownership and Internet usage. The survey shows that "some kind of gap has been crossed: Computers are part of everyday life for most Americans, and the Internet is close behind./

单选题The key to any successful garage sale (家庭旧物出售) is to get the word out. The best means of advertising your sale is to place an ad in the local newspaper. If you have a city and neighborhood paper, make sure you advertise in both. The ad should be large enough that it stands out. It should also include information on where the sale is located with directions, the "hot" items you"re selling and the time the sale will start and end. An ad should be placed at least two days before the sale and run until the day of your event. That way people can plan their route (路线) to the sale in advance. Signs are another great way to inform your community. Post them in places where people gather, such as stores and community centers. Some businesses have a central bulletin board (布告栏), which is the best place to advertise. Other places to post are at the local college or university campus. This is especially helpful if your sale is happening in August or early September when students have returned to school and are looking for cheap finds. Post signs around your neighborhood. You should also place both ads and direction signs, especially if you"re located on a side street without a major presence. Signs will attract and direct people. Just make sure you print in bold letters and use large direction signs so people can read the information from the front seat of their car.

单选题The history and development of the beverage that we know as coffee is varied and interesting, involving chance occurrences, political intrigue (阴谋) , and the pursuit of wealth and power. According to one story, a sheepherder named Kaldi as he tended his sheep noticed the effect of coffee beans on behavior. He noticed that the sheep became hyperactive after eating the red "cherries" from a certain plant when they changed pastures. He tried a few by himself, and was soon as overactive as his herd. The story relates that a monk happened by and scolded him for "partaking of the devil's fruit." However the monks soon discovered that this fruit from the shiny green plant could help them stay awake for their prayers. Coffee was introduced much later to countries beyond Arabia whose inhabitants believed it to be a delicacy and guarded its secret as if they were top secret military plans. The government for bade transportation of the plant out of the Moslem nations. The actual spread of coffee was started illegally. One Arab named Baba Budan smuggled beans to some mountains near Mysore, India, and started a farm there. Coffee was believed by some Christians to be the devil's drink. Pope Vincent III heard this and decided to taste it before he banished it. He enjoyed it so much and baptized it, saying, "Coffee is so delicious it would be a pity to let the infidels have exclusive use of it." Coffee today is grown and enjoyed worldwide, and is one of the few crops that small farmers in third-world countries can profitably export.
