单选题. Everyone becomes a little more forgetful as they get older, but men's minds decline more than women's, according to the results of a worldwide survey. Certain differences seem to be inherent in male and female brains: Men are better at maintaining and dealing with mental images (useful in mathematical reasoning and spatial skills), while women tend to excel at recalling information from their brain's files (helpful with language skills and remembering the locations of objects). Many studies have looked for a connection between sex and the amount of mental decline people experience as they age, but the results have been mixed. Some studies found more age-related decline in men than in women, while others saw the opposite or even no relationship at all between sex and mental decline. Those results could be improper because the studies involved older people, and women live longer than men. The men tested are the survivors, "so they're the ones that may not have shown such cognitive decline," said study team leader Elizabeth of the University of Warwick in England. People surveyed completed four tasks that tested sex-related cognitive skills: matching an object to its rotated form, matching lines shown from the same angle, typing as many words in a particular category as possible in the given time, e.g. "objects usually colored gray", and recalling the location of objects in a line drawing. The first two were tasks at which men usually excel; the latter are typically dominated by women. Within each age group studied, men and women performed better in their separate categories on average. And though performance declined with age for both genders, women showed obviously less decline than men overall.1. The underlined word in the first paragraph means ______.

单选题. There is a measurable relation between how much a person learns and his attitude toward the subject to be learned. When faced with a difficult learning task, one path to success is to concentrate on the positive aspects of the subject matter. If a student has a boring teacher, one solution is to look for the positive aspects of completing the course, regardless of how boring the teacher happens to be. To accomplish this might require a private tutor or some independent reading, but with the right attitude, success is possible. Over-achievers—students who do better than their test scores show—usually have a positive interest in learning. They may learn some things more slowly, and they may make more efforts, but, to compensate(补偿), they are often better at applying what they have learned. As long as they do not have emotional problems, they are successful. Under-achievers—those who function below their ability shown by test scores—often tend to allow a few negative factors to affect them. Because of their negative attitudes, they sometimes become unfairly critical of teachers. They allow themselves to get bored when it is not necessary. In short, their attitudes often cause them to learn less than over-achievers. If you learn to replace a negative attitude toward learning with something more positive, you are on the road to achieving almost any goal you desire. For example, if you realize a personal computer with a word processor would improve your performance, but have an attitude that keeps telling you that a computer is difficult to operate, you tend to make all kinds of excuses. In short, you resist making full use of a terrific tool, simply because your negative attitude prevents you from learning.1.
