单选题Personal computers and the Internet give people new choices about how to spend their time. Some may use this freedom to share less time with certain friends or family members, but new technology will also let them stay in closer touch with those they care most about. I know this from personal experience. E-mail makes it easy to work at home, which is where I now spend most weekends and evenings. (77) My working hours aren't necessarily much shorter than they once were, but I spend fewer of them at the office. This lets me share more time with my young daughter than I might have if she'd been born before electronic mail became such a practical tool. The Internet also makes it easy to share thoughts with a group of friends. Say you do something, fun--see a great movie, perhaps and there are four or five friends who might want to hear about it. If you call each one, you may tire of telling the story. With e-mail, you just write one note about your experience, at your convenience, and address it to all the friends you think might be interested. They can read your message when they have time, and read only as much as they want to. They can reply at their convenience, and you can read what they have to say at your convenience. E-mail is also an inexpensive way to stay in close touch with people who live far away. More than a few parents use e-mail to keep in touch, even daily touch, with their children off at college. (78) We just have to keep in mind that computers and the Internet offer another way of staying in touch. They don't eliminate (排除) any of the old ways.

单选题My father was a foreman of a sugar-cane plantation in Rio Piedras, Puerto Rico. My first job was to drive the oxen that plowed the cane fields. I would walk behind an ox, guiding him with a broomstick. For $1 a day, I worked eight hours straight, with no food breaks. It was very tedious work, but it prepared me for life and taught me many lasting lessons. Because the plantation owners were always watching us, I had to be on time every day and work as hard as I could. I"ve never been late for any job since. I also learned about being respectful and loyal to the people you work for. More important, I earned my pay. I was only six years old, but I was doing a man"s job. Our family needed every dollar we could make because my father never earned more than $18 a week. Our home was a three-room wood shack with dirty floor and no toilet. Nothing made me prouder than bringing home money to help my mother, father, two brothers and three sisters. This gave me self-esteem, one of the most important things a person can have. When I was seven, I got work at a golf course near our house. My job was to stand down the fairway and spot the balls as they landed so the golfers could find them. Losing a ball meant you were fired, so I never miss one. Some nights I would lie in bed and dream of making thousands of dollars playing golf and being able to buy a bicycle. The more I dreamed, the more I thought. Why not? I made my first golf club out of guava limb and a piece of pipe. Then I hammered an empty tin can into the shape of a ball. And finally I dug two small holes in the ground and hit the ball back and forth. I practiced with the same devotion and intensity I learned working in the field—except now I was driving golf balls with club, not oxen with a broomstick.

单选题Social change is more likely to occur in societies where there is a mixture of different kinds of people than in societies where people are similar in many ways. The simple reason for this is that there are more different ways of looking at things present in the first kind of society. There are more ideas, more disagreements in interest, and more groups and organizations with different beliefs. In addition, there is usually a greater worldly interest and greater tolerance in mixed societies. All these factors tend to promote social change by opening more areas of life to decision. In a society where people are quite similar, in many ways, there are fewer occasions for people to see the need or the opportunity for change because-everything seems to be the same. And although conditions may not be satisfactory, they are at least customary and undisputed. Within a society, social change is also likely to occur more frequently and more readily in the material aspects of the culture than in the non-material, for example, in technology rather than in values; in what has been learned later in life rather than what was learned early; in the less basic and less emotional aspects of society than in their opposites; in the simple elements rather than in the complex ones; in form rather than in substance; and in elements that are acceptable to the culture rather than in strange elements.
