填空题 In many cultures, traditional families, that is, married couples with children, {{U}}(1) {{/U}}. Until a decade ago, that was also the case in the United States. But the U.S. Bureau of Census reports people in more than {{U}}(2) {{/U}} now live in some other arrangements. For the first time in history, the number of Americans living alone has {{U}}(3) {{/U}} of historically dominant households—married couples with children. In 1960, 45% of American households {{U}}(4) {{/U}} with children. Today it is less than 25%. In the past 10 years, the number of {{U}}(5) {{/U}} has grown faster than the number of family households. But the {{U}}(6) {{/U}} that the American {{U}}(7) {{/U}}. Although the rate of married-with-children household is still declining, it is declining {{U}}(8) {{/U}} than during the 1960s and 1970s, and married couples with or without children still {{U}}(9) {{/U}} all American households. What really should be noted is actually {{U}}(10) {{/U}} in a lot of the numbers in the past 10 years, compared to the structure of households 20 or 30 years before. And for example, in 1960, if we go back 47 years, {{U}}(11) {{/U}} were married-couple households. The number {{U}}(12) {{/U}} in 1970, and down to 60% in 1980. But then over the past two decades, the rate of decline has slowed down quite a bit: it went down to {{U}}(13) {{/U}} and 52% in 2000. The number of {{U}}(14) {{/U}} is declining for several reasons. More than ever before, men and women are {{U}}(15) {{/U}}. Also the number of {{U}}(16) {{/U}} is growing much faster than the number of married couples. The 2000 census shows that {{U}}(17) {{/U}}. First the aging of the American population and the growing number of both young and old people living alone are the main reasons the average American household {{U}}(18) {{/U}}, just over two and a half people per household.

填空题 Why should mankind explore space? Perhaps the best reason for exploring space is our built-in {{U}} {{U}} 1 {{/U}} {{/U}}predisposition to expand into all possible parts of space. Culturally nearly every successful civilization has been willing to {{U}} {{U}} 2 {{/U}} {{/U}}. In exploring, {{U}} {{U}} 3 {{/U}} {{/U}}of surrounding areas may be learned and prepared for. Exploration also allows {{U}} {{U}} 4 {{/U}} {{/U}}to be located. These resources translate into {{U}} {{U}} 5 {{/U}} {{/U}}and success at survival. Resources may be more than {{U}} {{U}} 6 {{/U}} {{/U}}assets. Knowledge or {{U}} {{U}} 7 {{/U}} {{/U}}acquired in exploring or preparing to explore always filter from the developers to the general {{U}} {{U}} 8 {{/U}} {{/U}}. Techniques may be {{U}} {{U}} 9 {{/U}} {{/U}}or {{U}} {{U}} 10 {{/U}} {{/U}}, allowing the people in a society to better {{U}} {{U}} 11 {{/U}} {{/U}}those within or outside the culture. Better understanding may lead to better use of resources or a lessening of outright {{U}} {{U}} 12 {{/U}} {{/U}}for the resources. The chance of a large {{U}} {{U}} 13 {{/U}} {{/U}}or comet hitting Earth, though small, will {{U}} {{U}} 14 {{/U}} {{/U}}. Without the ability to reach out across space, the chance to {{U}} {{U}} 15 {{/U}} {{/U}}ourselves might not exist. Our genetic {{U}} {{U}} 16 {{/U}} {{/U}}will allow humans to move into unoccupied parts of space and {{U}} {{U}} 17 {{/U}} {{/U}}. If one group is eliminated, the {{U}} {{U}} 18 {{/U}} {{/U}}as a whole survives. The more a culture expands, the less chance of it becoming {{U}} {{U}} 19 {{/U}} {{/U}}.

填空题 I'll start my {{U}} {{U}} 1 {{/U}} {{/U}}by telling you a story. A young woman from {{U}} {{U}} 2 {{/U}} {{/U}}came to New York and got a job at a factory {{U}} {{U}} 3 {{/U}} {{/U}}by a Chinese. One day, her Chinese boss handed her a red envelope with 20 dollars. She threw the envelope back at her boss. Why? It is {{U}} {{U}} 4 {{/U}} {{/U}}to give money to young {{U}} {{U}} 5 {{/U}} {{/U}}people on the Chinese New Year. However, from her viewpoint, giving her money meant that he was asking her for sexual {{U}} {{U}} 6 {{/U}} {{/U}}. This story shows an action can have totally {{U}} {{U}} 7 {{/U}} {{/U}}meanings in different cultures. I'll say something more to {{U}} {{U}} 8 {{/U}} {{/U}}my point. First, in most Western countries, {{U}} {{U}} 9 {{/U}} {{/U}}often {{U}} {{U}} 10 {{/U}} {{/U}}some sort of {{U}} {{U}} 11 {{/U}} {{/U}}, such as a {{U}} {{U}} 12 {{/U}} {{/U}}or a kiss. But most Asian people don't feel as {{U}} {{U}} 13 {{/U}} {{/U}}touching in public. Another different behavior is the use of {{U}} {{U}} 14 {{/U}} {{/U}}. Americans are quick to use people's first names, but people in most cultures prefer to be {{U}} {{U}} 15 {{/U}} {{/U}}as "Mr. Brown" or "Ms. Honda", for example. Now I want to discuss eating {{U}} {{U}} 16 {{/U}} {{/U}}. In some cultures eating everything on your plate is considered {{U}} {{U}} 17 {{/U}} {{/U}}. However, Americans consider a {{U}} {{U}} 18 {{/U}} {{/U}}plate a sign of {{U}} {{U}} 19 {{/U}} {{/U}}with the food. Finally, I want to say something about gift-giving, which in many cultures has strict rules. For example, never give {{U}} {{U}} 20 {{/U}} {{/U}}flowers to people from Iran, which means you hate them!

填空题 If the entire human species were a single individual, that person would long ago have been declared mad. The insanity would not lie in the {{U}}(1) {{/U}} of the human mind—though it can be a black and raging place indeed. And it certainly wouldn't lie in the {{U}}(2) {{/U}}. The madness would lie instead in the fact that both of those qualities, the savage and the splendid, can exist in one creature, one person, {{U}}(3) {{/U}}. We're a species that is capable of almost dumbfounding kindness. We nurse one another, {{U}}(4) {{/U}}, weep for one another. Ever since science taught us how, we willingly tear the {{U}}(5) {{/U}} and give them to one another. And at the same time, we {{U}}(6) {{/U}}. The past 15 years of human history are {{U}}(7) {{/U}} of those subatomic particles that are created in accelerators and {{U}}(8) {{/U}}, but in that fleeting instant, we've visited untold horrors on ourselves. As the {{U}}(9) {{/U}} species the planet has produced, we're also the lowest, cruelest, most blood-drenched species. That's {{U}}(10) {{/U}}. What does, or ought to, separate human beings with other species is our highly developed {{U}}(11) {{/U}}, a primal understanding of good and bad, of right and wrong, of what it means to suffer not only our own pain, but also the pain of others. That quality is {{U}}(12) {{/U}} of what it means to be human. Why it's an essence that so often spoils, no one can say. Morality may be a hard concept to grasp, but {{U}}(13) {{/U}}. Psychologists believe even kids can feel the difference between a matter of morality and one of {{U}}(14) {{/U}} innately. Of course, the fact is that a child will sometimes hit and won't feel particularly bad about it either—unless he's caught. The same is true {{U}}(15) {{/U}} or despots who slaughter. The rules we know, even the ones we intuitively feel, are by no means {{U}}(16) {{/U}}. Where do those intuitions come from? And {{U}}(17) {{/U}} about following where they lead us? Scientists can't yet answer those questions, but that hasn't {{U}}(18) {{/U}}. Brain scans are providing clues. Animal studies are providing more. {{U}}(19) {{/U}} are providing still more. None of this research may make us behave better, not right away at least. But all of it can help us understand ourselves— {{U}}(20) {{/U}} perhaps, but an important one.

填空题 The US seems to be fighting a losing battle against the bulge, with a new report from the Trust for America's Health showing that {{U}} {{U}} 1 {{/U}} {{/U}}have increased in 31 states. According to a report published recently by the Department of Health, there are now {{U}} {{U}} 2 {{/U}} {{/U}}where more than a quarter of the adult population is obese. Nevada is the only state that {{U}} {{U}} 3 {{/U}} {{/U}}in the percentage of obese adults compared to last year's report. Obesity rates remained the same {{U}} {{U}} 4 {{/U}} {{/U}}. Overall, adult obesity rose from 15 percent in 1980 to {{U}} {{U}} 5 {{/U}} {{/U}}. Taken together, individuals who are either overweight or obese comprise {{U}} {{U}} 6 {{/U}} {{/U}}of the US adult population. {{U}} {{U}} 6 {{/U}} {{/U}}is increasing at an even more alarming pace, having {{U}} {{U}} 8 {{/U}} {{/U}}between 1980 and 2012. The report notes that obesity can lead to {{U}} {{U}} 9 {{/U}} {{/U}}including diabetes, stroke and cancer. The obesity epidemic in America {{U}} {{U}} 10 {{/U}} {{/U}}. The report is based on data from telephone interviews with {{U}} {{U}} 11 {{/U}} {{/U}}. The rates are based on averages calculated over a three-year period, from 2010 to 2012. Colorado {{U}} {{U}} 12 {{/U}} {{/U}}, at 16.9 percent of its adult population. Hawaii {{U}} {{U}} 13 {{/U}} {{/U}}, while Massachusetts ranked third. The five leanest states in the country are also {{U}} {{U}} 14 {{/U}} {{/U}}. However, despite lower rates in some areas, the general trend toward obesity is on the rise almost everywhere, affecting {{U}} {{U}} 15 {{/U}} {{/U}}. Poor nutrition and lack of exercise are at the root of America's obesity epidemic, the report suggests. The report {{U}} {{U}} 16 {{/U}} {{/U}}for doing too little to combat obesity and offers a 20-step action plan. Among its recommendations are {{U}} {{U}} 17 {{/U}} {{/U}}on foods; supporting community-driven efforts to increase access to healthy foods in low-income areas; improving the nutritional content of foods and beverages {{U}} {{U}} 18 {{/U}} {{/U}}; providing communities with more and better sidewalks, parks and bike paths; offering {{U}} {{U}} 19 {{/U}} {{/U}}in schools; and. promoting employer-sponsored programs to increase physical activity and to provide {{U}} {{U}} 20 {{/U}} {{/U}}for obesity prevention.

填空题 About {{U}} {{U}} 1 {{/U}} {{/U}}years ago, Earth entered the latest interglacial period. The {{U}} {{U}} 2 {{/U}} {{/U}}pattern for an interglacial period is that there is the most carbon dioxide and methane gas which are greenhouse gases. And then the concentration of greenhouse gases gradually goes down. Now, the climate continues to warm for a while because there is a {{U}} {{U}} 3 {{/U}} {{/U}}effect. But gradually as the concentration of greenhouse gases goes down, Earth starts to cool again, and eventually you {{U}} {{U}} 4 {{/U}} {{/U}}back into an Ice Age. In the latest interglacial period, this pattern did not {{U}} {{U}} 5 {{/U}} {{/U}}now. What was different about this period than the other ones? One big {{U}} {{U}} 6 {{/U}} {{/U}}is human activity. the agricultural revolution—people began {{U}} {{U}} 7 {{/U}} {{/U}}crops and animals for food instead of {{U}} {{U}} 8 {{/U}} {{/U}}for them. Some climate {{U}} {{U}} 9 {{/U}} {{/U}}propose that perhaps humanity was having an effect on the climate since the agricultural revolution. When you grow crops and {{U}} {{U}} 10 {{/U}} {{/U}}animals, you cut down the {{U}} {{U}} 11 {{/U}} {{/U}}, you end up with much more carbon in the atmosphere. Methane forms in large concentration above {{U}} {{U}} 12 {{/U}} {{/U}}, which increases its amount in the atmosphere. So agriculture could have a {{U}} {{U}} 13 {{/U}} {{/U}}effect on the {{U}} {{U}} 14 {{/U}} {{/U}}of Earth's atmosphere. The agricultural revolution was {{U}} {{U}} 15 {{/U}} {{/U}}by {{U}} {{U}} 16 {{/U}} {{/U}}an Ice Age. But {{U}} {{U}} 17 {{/U}} {{/U}}and the burning of {{U}} {{U}} 18 {{/U}} {{/U}}fuels have drastically {{U}} {{U}} 19 {{/U}} {{/U}}carbon dioxide in the atmosphere. So we enter into uncharted {{U}} {{U}} 20 {{/U}} {{/U}}now in terms of the amount of carbon dioxide.

填空题{{B}}Part A Note-taking And Gap-filling{{/B}} Directions: In this part of the test you will hear a short talk. You will hear the talk ONLY ONCE. While listening to the talk, you may take notes on the important points so that you can have enough information to complete a gap-filling task on a separate ANSWER BOOKLET. You will not get your ANSWER BOOKLET until after you have listened to the talk. When you enter into a conversation, you expect the other person to communicate exactly as you do, and the other person expects you to communicate just as he or she does. If these expectations are not met, communication {{U}}(1) {{/U}} begins. On the other hand, in some situations, a person may expect the other person not to communicate in a {{U}}(2) {{/U}} style. When two people start to develop an {{U}}(3) {{/U}} relationship, complementary communication {{U}}(4) {{/U}} often emerge. Once you begin to know and like another individual, you accept or become {{U}}(5) {{/U}} of his or her communication style and the inherent {{U}}(6) {{/U}} and weakness. It would not be {{U}}(7) {{/U}} for you to manage communication conflicts if you remember the following {{U}}(8) {{/U}} -step process: First, you should understand your own {{U}}(9) {{/U}} style of communication. Second, you should be able to {{U}}(10) {{/U}} the other person's dominant style of communication. Third, you need to use different {{U}}(11) {{/U}} of communication to deal with different expectations, so as to accomplish your {{U}}(12) {{/U}}. Fourth, you will develop new expectations for your {{U}}(13) {{/U}} communication activity. A person's communication style is {{U}}(14) {{/U}} and {{U}}(15) {{/U}} influenced. Your personality also interacts with your style of communication. Remember descriptions of {{U}}(16) {{/U}} such as charming, rude, dynamic, boring, pleasant, and dishonest are not communication style characteristics. In the process of analyzing and {{U}}(17) {{/U}} communication events, the first step is to identify the other person's style of communication. The next step is to {{U}}(18) {{/U}} your style to meet the other person's {{U}}(19) {{/U}}. By controlling your style of communication, you can learn to control the {{U}}(20) {{/U}} of the communication activity.

填空题We often hear and read about controversial issues in science and technology. For example, will radiation from electronic equipment 1 the environment? Should the DNA samples of 2 be put into a computer data base so investigators can compare it to the DNA of blood at 3 ? Should medical scientists change gene structures to prevent 4 or to create more perfect human beings? While people are arguing about these and other 5 , technology continues to influence every aspect of everyday life—the home health and education, 6 , and so on. Some people carry on 7 with computers—their own or the ones available at 8 like cafes, social centers, libraries, and so on. Communicating with others on 9 or in 10 , computer users can get to know people they might never meet 11 Some look for 12 by computer: they might place 13 with photos on the screen or even produce 14 for their Websites.

But now, writing to communicate has returned 17 , or email, which is a way of 18 from one computer to another. When a computer is ready to mail a letter, it 19 —that is, a central computer that collects and distributes electronic information. Delivery time from the sender to the receiver is no more than a few seconds, even from one country to another. For some computer users, the wish to 20 with others makes them want to write better.

填空题 A lot of people think we could be headed for trouble by tampering with Mother Nature and producing genetically altered food. But those who {{U}}(1) {{/U}} say it's no more unnatural than traditional selective breeding, to say nothing about {{U}}(2) {{/U}} and chemical pesticides. Most Canadians regularly eat bio-engineered food. Anyone who consumes cheese, potatoes, tomatoes,{{U}} (3) {{/U}} is taking in genetically modified (GM) food. In addition, {{U}}(4) {{/U}} contain GM ingredients. In fact, around 65% of the food we get from the shops has some genetically modified component. GM food does not {{U}}(5) {{/U}} in Canada, so most of us don't know we are eating it. Some of the items that have {{U}}(6) {{/U}} GM material might surprise you. They include chocolate bars, baby food, margarine, {{U}}(7) {{/U}}, ice cream, {{U}}(8) {{/U}}, cereals, and cookies. {{U}} (9) {{/U}} have used GM foods for centuries; if they hadn't, we'd probably still be {{U}}(10) {{/U}}. They've refined the foods we eat through selective crossbreeding, combining different types of wheat, and {{U}}(11) {{/U}}. Today, however, genetic engineering is no longer just a case of mixing different varieties of {{U}}(12) {{/U}}. Now, genes from completely different life forms are being combined—fish genes into tomatoes to {{U}}(13) {{/U}}, for example. Such "tampering with Nature" makes a lot of people anxious. They wonder if the foods that come out of genetic modification are {{U}}(14) {{/U}}. Scientists say they are completely safe; GM is just a way of {{U}}(15) {{/U}} to make it possible for them to survive without the use of pesticides and to {{U}}(16) {{/U}}.

填空题Many privacy-protection Web sites work by inserting themselves as 1 and masking the Internet addresses of users" computers. If a user in a country with 2 goes to a privacy-protection site, that site becomes a shell that can be used to explore the Web.
