阅读材料,回答下面的题目。The New Technology ApplicationOn a more mundane level, third-generation mobile telephones, despite all the delays and the billions squandered on 3G licenses by telecom firms, are still expected to offer consumers high-speed, always on mobile internet access, complete with video, in the next few years.Rapidly proliferating "WiFi" networks already offer wireless access on a local basis. Tiny tracking chips called radio-frequency identification devices are being used as pet passports.Soon they will be small, powerful and cheap enough to be implanted into everything form humans to milkcartons recording and transmitting real-time medical data, or serving as a form of inventory control.Sensors of every kind, including video cameras, should also become much smaller and cheaper.Forrester Research, a technology consultancy, predicts that 14 billion such devices will be connected to the internet by 2005.How rapidly such new technology is introduced will depend on a number of factors the state of the economy, the supply of investment capital and the appetite of consumers for new products or services ! Fortunes will be made and lost many times over.But whatever happens, the power of computing and communications look set to continue to grow, and its price to fall, at a steady rate for the next few decades.That will make it possible, at least in rich countries, to record most human interactions, wherever and whenever they take place, and to store and analyze this ocean of data at low cost.For the sake of argument, this survey will assume that we are heading towards a networked society of ubiquitous, mobile Communication capable of constant monitoring.Whether this arrives in 20,30 or 40 years does not really matter.The point is that the destination seems not merely possible, but probable, so it is not toosoon to ask: What do we want this technology to do?The internet has already thrown up a host of legal and political conundrums, but, these are only a small foretaste of the dilemmas about privacy, security, intellectual property and the nature of government itself that will have to be faced over the coming decades.The debate has already begun. This survey will outline some of main issues, and speculate on the way they are likely to go. Radio-frequency identification devices__________.

We take fishes from the ocean-millions of kilograms of fish, every year, to51millions of people. We even52their bones for fertilizer. We take minerals from the ocean. One way to get salt is to53seawater in shallow basin and leave until it evaporates( 蒸发 ). Along with salt, other minerals are left 54 evaporation.Much gold and silver drift dissolved in the waters of the sea, too. But the sea does not give them 55 by simpleevaporation.56gifts from the sea are pearls, sponges( 海绵) and seaweed. Pearls57jewelry. Natural sponges become cleaning aids. Seaweed becomes 58 of many kinds-even candy, and ice cream - as well as medicine. Believe it or not, fresh water is another 59 from the sea. We cannot drink ocean water. Some of its contents may. 60 illness. But ocean water becomes fresh water when the salts are 61 . In the future, we will find ourselves 62 more and more on fresh water from the sea. The sea63us food, fertilizer, minerals, water, and other gifts. What do we give the sea? Garbage. We pollute the ocean 64 we use it as a garbage dump. Huge as it is, the ocean cannot hold all the water that we pour into it. 65 garbage into the ocean is killing off sea life. Yet as the world population grows, we may need the sea and its gifts ,more than ever.请在第___________处填上正确答案.
根据材料,完成下面的题目。Kicking the Habit What is a bad habit? The most definition is that it is something that we do regularly, almost without thinking about it. and which has some sort of negative consequence. This consequence could affect those around us, or it could affect us personally. Those who deny having bad habits are probably lying. Bad habits are part of what makes us human. Many early habits, like sucking out thumb, are broken when we are very young. We are either told to stop doing it by our parents, or we consciously or subconsciously observe that others do not have the same habit, and we gradually grow out of it. It is when we intentionally or unintentionally pick up new habits in our later childhood or early adulthood that it becomes a problem. Unless we can break that habit early on, it becomes a part of our life, and becomes "programmed" into our brain. A recent study of human memory suggests that no matter how hard we try to change out habits, it is the old ways that tend to win, especially in situations where we are rushed, stressed or overworked. Habits that we thought we had got rid of can suddenly come back. During the study program, the researchers showed a group of volunteers several pictures, and gave them words to associate with them. They then showed the volunteers the same picture again, and gave them new words to associate with them. A few days later, the volunteers were given a test. The researchers showed them the pictures, and told them to respond with one of the words they had been given for each one. It came as no surprise that their answers were split between the first set of words and second. Two weeks later, they were given the same test again. This time, most of them only gave the first set of words. They appeared to have completely forgotten the second set.The study confirms that the responses we learn first are those that remain strongest over time. We may try to change out ways, but after a while, the response that comes to mind first is usually the first one we learned. The more that response is used, the more automatic it becomes and the harder it becomes to respond in any other way. The study therefore suggests that over time, our bad habits also become automatic, learned behavior. This is not good news for people who pick up bad habits early in life and now want tochange or break them. Even when we try to put new, good intentions into practice, those previous learned habits remain stronger in more automatic, unconscious forms of memory.Boys usually develop bad habits when they are very young.

根据以下材料回答下面的题目:The Emic and Etic ApproachesResearchers who are unfamiliar with the cultural and ethnic groups they are studying must take extra precautions to shed any biases they bring with them from their own culture. For example, they must make sure they construct measures that are meaningful for each of the cultural or ethnic minority groups being studied.In conducting research on cultural and ethnic minority issues, investigators distinguish between the emic approach and the etic approach. In the emic approach, the goal is to describe behavior in one culture or ethnic group in terms that are meaningful and important to the people in that culture or ethnic group, without regard to other cultures or ethnic groups. In the eric approach, the goal is to describe behavior so that generalizations can be made across cultures. If researchers construct a questionnaire in an emic fashion, their concern is only thatthe questions are meaningful to the particular culture or ethnic group being studied. If, however, the researchers construct a questionnaire in an etic fashion, they want to include questions that reflect concepts familiar to all cultures involved.How might the emic and etic approaches be reflected in the study of family processes? In the emic approach, the researchers might choose to focus only on middle-class White families, without regard to whether the information obtained in the study can be generalized or is appropriate for ethnic minority groups. In a subsequent study, the researchers may decide to adopt an eric approach by studying not only middle-class White families, but also lower-income White families, Black American families, Spanish American families, and Asian American families. In studying ethnic minority families, the researchers would likely discover thatthe extended family is more frequently a support system in ethnic minority families than in White American families. If so, the emic approach would reveal a more different pattern of family interaction than would the etic approach, documenting that research with middle class White families cannot always be generalized to allethnic groups.According to the first paragraph, researchers unfamiliar with the target cultures are inclined to__________
