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.
回答下面的题目:The First Settlement in North AmericaIt is very difficult to say just when colonization began. Thefirst hundred years after Christopher Columbus journey of discovery in 1492 didnot produce any settlement on the North America continent but rather someSpanish trading posts further south, a great interest in gold and adventure,and some colorful crimes in which the English had their part. John Cahot,originally from Genoa but a citizen of Venice, was established as a trader inBristol, England, when he made a journey in 1497. But his ship,the Matthew,with its crew of eighteen, did no more than see an island prohably off the NewEngland coast) and return home. He and his son made further voyages across thenorth Atlantic which enabled the English crown to claim a "legal"title to North AmericA.But for a long time afterwards the Europeans interestin America was mainly confined to the Spanish activities further south.The first beginning of permanent settlement in North America werenearly a hundred years after Columbus first voyage. The Englishman Sir WalterRaleigh claimed the whole of North America for England, calling it VirginiA.In1585 he sent a small group of people who landed in Roanoke Island,but theystayed only for a year and then went back to England with another expedition,led by Drake,in 1587. A second group who landed in 1587 had all disappearedwhen a further expedition arrived in 1590.The first permanent settlement in North America was in 1607.English capitalists founded two Virginia companies, a southern one based inLondon and a northern one based in Bristol. It was decided to give the name NewEngland to the northern areA.The first settlers in Virginia were little more thanwage slaves to the company. All were men and the experiment was not verysuccessful. Many dieD.Those who survived lived in miserable conditions. By1619 the colony had only a thousand people.We know for sure that colonization began at the end of the15th century,

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__________
根据材料,回答问问题。The Science of the Future Until recently, the "science of the future" was supposed to be electronics and artificialintelligence. Today it seems more and more likely that the next great breakthroughs intechnology will be brought through a combination of those two sciences with organic chemistryand genetic engineering. This combination is the science of biotechnology. Organic chemistry enables us to produce marvelous synthetic (合成的) materials. However,it is still difficult to manufacture anything that has the capacity of wool to conserve heat and alsoto absorb moisture. Nothing that we have been able to produce so far comes anywhere near thecombination of strength, lightness and flexibility that we fred in the bodies of ordinary insects.Nevertheless, scientists in the laboratory have already succeeded in "growing" a material that has many of the characteristics of human skin. The next step may well be "biotech heartsand eyes" which can replace diseased organs in human beings. These will not be rejected by thebody, as is the case with organs from humans. The application of biotechnology to energy production seems even more promising. In1996 the famous science-fiction writer, Arthur C. Clarke, many of whose previous predictionshave come true. He said that we may soon be able to develop remarkably cheap and renewablesources of energy. Some of these power sources will be biological. Clarke and others havewarned us repeatedly that sooner or later we wi/1 have to give up our dependence on non-renewable power sources. Coal, oil and gas are indeed convenient. However, using them alsomeans creating dangerously high levels of pollution. It will be impossible to meet the growingdemand for energy without increasing that pollution to catastrophic (灾难性的) levels unlesswe develop power sources that are both cheaper and cleaner. It is attempting to think that biotechnology or some other "science of the future" can solveour problems. Before we surrender to that temptation we should remember nuclear power.Only a few generations ago it seemed to promise/imit/ess, cheap and safe energy. Today thosepromises lie buried in a concrete grave in a place called Chernobyl, in the Ukraine.Biotechnology is unlikely, however, to break its promises in quite the same or such a dangerousway.According to the passage, the science of the future is likely to be__________
