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:Academic MobilityScholars and students have always been great travelers. "Academic mobility" is now often stated as a fundamental necessity for economic and social progress in the world, but it is certainly nothing new. Serious students were always ready to go abroad in search of the most stimulating teachers and the most famous academies; in search of the purest philosophy, the most effective medicine, the likeliest road to gold.Mobility of this kind means also mobility of ideas, their transference across frontiers, their simultaneous impact upon many groups of people. The point of learning is to share it, whether with students or with colleagues; one presumes that only eccentrics have an interest in being credited with a startling discovery, or a new technique. It must also have been reassured to know that other people in other parts of the world were about to make the same discovery or were thinking along the same lines, and that one was not quite alone, confronted by inquisition, ridicule or neglect.In the twentieth century, and particularly in the last twenty years, the old footpaths of the wandering scholars have become vast highways. The vehicle which has made this possible has of course been the aero plane, making contact between scholars even in most distant places immediately feasible, and providing for the very rapid transmission of knowledge. Apart from the vehicle itself, it is fairly easy to identify the main factors which have brought about the recent explosion in academic movement. Some of these are purely quantitative and require no further mention: there are far more centers of leaming, and a far greater number of scholars and students.In addition, one must recognize the very considerable multiplication of disciplines, particularly in the sciences, which by widening the total area of advanced studies has produced an enormous number of specialists whose particular interests ale precisely defined. These people would work in some isolation if they were not able to keep in touch with similar isolated groups in other countries.It can be concluded from the passage that "academic mobility"__________
