回答下面的题目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 to change 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：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"__________

scholars can meet each other more easily

解析：【解析】事实细节题，第三段最后一句说“…the aeroplane，making contact between scholars even in most distant places immediately feasible…”，与选项D意思一致，文中还提到“providing for the very rapid transmission of knowledge”，但A、B、C项均不符合。
