单选题If you" re among the two-thirds of working women who earn their living in offices, it" s far too early to let out a sigh of relief about how healthy and happy your working environment is. If you are among that number, however, you probably already know that. Without question, office work doesn" t pose the risks or dangers of jobs in manufacturing, mining, or even agriculture. The closest many of us come to working with a chemical is when we get toner smudges on our hands from photocopies or apply dabs of correcting fluid. By most people" s standards, even the dingiest office beats an assembly line, factory, or a mine for atmosphere. A white collar isn" t exactly protective clothing, however. More than 40,000 disabling injuries(including back and neck injuries and muscle pulls)and 200 safety-related deaths occur in offices each year. There are also considerable other stresses associated with office work, including boredom, repetitiveness, and low status, which can affect health. One thing is certain: as the numbers of office workers grow, so too will office health problems. In the 1950s and early 1960s the office had begun its climb to economic fame and power, jockeying into position to replace industry as the largest employer in the United States. It was the beginning of what author John Naisbitt calls the "information age" in his influential book Megatrends, "Now," he says, "more than 65 percent of us work with information as programmers, teachers, clerks, secretaries, accountants, stock brokers, managers, insurance people, bureaucrats, lawyers, bankers, and technicians. And many more workers hold information jobs within manufacturing companies."

单选题In bringing up children, every parent watches eagerly the child"s acquisition(获得) of each new skill—the first spoken words, the first independent steps, or the beginning of reading and writing. It is often tempting to hurry the child beyond his natural learning rate, but this can set up dangerous feeling of failure and states of worry in the child. This might happen at any stage. A baby might be forced to use a toilet too early, a young child might be encouraged to learn to read before he knows the meaning of the words he reads. On the other hand, though, if a child is left alone too much, or without any learning opportunities, he loses his natural enthusiasm for life and his desire to find out new things for himself. Parents vary greatly in their degree of strictness towards their children. Some may be especially strict in money matters, others are severe over times of coming home at night or punctuality for meals. In general, the controls imposed represent the needs of the parents and the values of the community as much as the child"s own happiness. As regards the development of moral standards in the growing child, consistency is very important in parental teaching. To forbid a thing one day and excuse it the next is no foundation for morality(道德). Also, parents should realize that "example is better than precept ". If they are not sincere and do not practice what they preach (说教), their children may grow confused and emotionally insecure when they grow old enough to think for themselves, and realize they have been to some extent fooled. A sudden awareness of a marked difference between their parent"s principles and their moral can be a dangerous disappointment.

单选题As human children are unusually dependent far an unusually long time, it's obvious that every society must provide a domestic context in which the children are brought up and educated. In present-day English, the word "family" has two meanings: firstly, the (1) group of parents and children; and secondly, a (2) of relations who might be expected to (3) at a wedding or a (4) . At the first level, my brothers and sisters and myself are all in the same (5) as children, but in different ones as parents; but at the second (6) , we're all in the same family from start to finish. As nuclear families become more (7) , families of relations become more dispersed (分散). The young mother can still talk to her Mum on the phone, but she can't ask her to (8) for a few minutes to watch the baby. Ideas about the (9) of women have been changing: wives are thought to be the (10) of their husbands rather than their (11) . But perhaps they're more (12) enslaved to their children than before. The point is that there doesn't seem to be any (13) . There is a genuine (14) between the right of the woman to be treated as a free and self-respected (15) , and the right of the child to demand care and (16) We have created for ourselves three (17) : social equality of men and women; (18) of the marriage; and lifelong love and (19) between parents and children. However, we have (20) a social system in which it's quite impossible for these factors to co-exist.

单选题In the United States, it is important to be on time, or punctual, for an appointment, a class, etc. However, this may not be true in all countries. An American professor discovered this difference while teaching a class in a Brazilian (巴西的) university. The two-hour class was scheduled to begin at 10 A. M. and end at 12. On the first day, when the professor arrived on time, no one was in the classroom. Many students came after the scheduled time. Several arrived half an hour later. Few apologized for their lateness. Were these students being rude? He decided to study the students' behavior. The professor talked to American and Brazilian students about lateness in both an informal and a formal situation, at a lunch with a friend and in a university class. He found that if they had a lunch appointment with a friend, the average American student defined lateness as 19 minutes after the agreed time. However, the average Brazilian student felt the friend was late after 33 minutes. In an American university, classes not only begin at the scheduled time in the United States, but also end at the scheduled time. In the Brazilian class, only a few students left the class at 12:00; many remained past 12:30 to discuss the class and ask more questions. While arriving late may not be very important in Brazil, neither is staying late.

单选题Most injures can be prevented, provided a parent goes about it the right way. Mr. Grant was a skilled and capable surgeon. His wife--intelligent, charming and a qualified nurse--had suggested they see me about their 16-month-old son, Neville. Mrs. Grant spoke first. "We're both professional people, and I guess we're supposed to know more than most people. It hurts us to admit our little Neville is such a problem." "He's all over the house, climbing, handling things he's not supposed to be touching," Mr. Grant interrupted, "and we're afraid he'll badly injure himself and it'll be our fault." "Does he have some understanding of the word ' no'," I asked… "That's just it, we can't be sure if he has or not. Sometimes he seems to understand, but at other times he just doesn't seem to mind when we say 'no'," the father replied. "Teaching a child the meaning of the word 'no' can be crucial in preventing accidents. Unless your Neville can understand the true meaning of 'no'--and only you two can teach it to him at this stage--there's bound to be trouble," I stated emphatically. Children between the age of one and two often injure themselves, sometimes quite seriously, if they've not been properly trained to respond to the word 'no'. It's only natural that our child, having only recently learned to move about, should want to explore and find out about this big, beautiful world around him. His sense of curiosity gets the better of him. To begin with, the fewer "no's" you tell your child, the better off things it will be. This can be done by thoughtfully removing from the room all those forbidden objects you suspect he'll reach for. You must be absolutely consistent. Be quick, alert, and fast-acting in preventing him from reaching for a forbidden object. Draw his attention, towards something else he can play with.
