　　fitting together pieces of information or working through a problem. Such personal encounters are the “payoff” in education. A teacher may direct you to learning and even encourage you in it梑ut no teacher can make the

　　excitement or the joy happen. That's up to you.

　　A research paper, t assigned in a course and perhaps checked at various stages by an instructor,

　　leads you beyond classrooms,

　　beyond the texts for classes and into a process where the joy of discovery and learning can come to you many times. Preparing the research paper is an active and individual process, and an ideal learning process. It provides a structure within which you can make exciting discoveries,

　　of knowledge and of self,

　　which are basic to education. The research paper also gives you a chance to individualize a school assignment,

　　to suit a piece of work to your own interests and abilities and to show others what you can do. Writing a research paper is more than a classroom exercise. It is an experience in searching out,

　　understanding and synthesizing,

　　which forms the basis of many skills applicable to both academic and nonacademic tasks. It is,

　　in the fullest sense,

　　a discovery,

　　an education. So,

　　to produce a good research paper is both a useful and a thoroughly satisfying experience!

　　To some,

　　the thought of having to write an assigned number of pages,

　　often more than ever produced before,

　　is disconcerting. To others,

　　the very idea of having to work independently is threatening. But there is no need to approach paper assignment with anxiety,

　　and nobody should view the research paper as an obstacle to overcome. Instead,

　　consider it a goal to accomplish,

　　a goal within reach if you use the help this passage can give you.

　　Compared to adults,

　　children seem to be moving constantly.So it's no surprise that most parents who are quizzed about their child's physical activity level describe their children as fairly active.But a new study of nearly 2, 000 British school children suggests that many parents overestimate the amount of physical activity their children are really getting.

　　The researchers equipped 1,

　　892 British school children,

　　ages 9 and 10,

　　with accelerometers that measure all physical activity during a given time period.The research,

　　known as the Speedy Study collected the exercise data from children at 92 schools in Norfolk,

　　England,

　　between April and July 2007.

　　A child was regarded inactive if he or she recorded less than an hour a day of physical activity.Although the majority of children studied were getting enough physical activity, a_sizable_minority_of_children_were_not. Overall,

　　39 percent of girls and 18 percent of boys studied were getting less than an hour of physical activity each day.

　　But if you asked the parents of the inactive children to describe their child's activity level,

　　the vast majority—80 percent—described their children as fairly or very physically active,

　　according to the findings published in the American Journal of Preventive Medicine.Interestingly,

　　the children themselves had more awareness about their lack of physical activity.Overall,

　　40 percent of children overestimated their physical activity.

　　But it wasn't the parents of overweight children who were most likely to guess wrong about physical activity levels.The parents who were most out of touch about their child's physical fitness were more likely to have children who were slim.Parents of girls were also more likely to overestimate physical activity.The researchers noted that parents should be educated about the importance of physical activity for children even if the child is not overweight.

　　“Parents of slim children appear to assume that their children are adequately active,

　　” the study authors reported.“Increasing awareness regarding health benefits of physical activity beyond weight control might help have a correct idea of physical activity levels and encourage behavior change.”

　　20．According to the Speedy Study

　　what kind of children can be judged physically inactive?

　　A．Slim children.

　　B．Children with less than an hour a day of physical activity.

　　C．Overweight children.

　　D．Children out of

　　touch with their parents for a long time.

　　21．What does the writer probably

　　mean by saying “a sizable minority of children were not” in Paragraph 3?

　　A．The

　　amount of children's physical activity is far from the writer's

　　satisfaction.

　　B．A lot of children were not getting enough physical activity.

　　C．A small number of children didn't overestimate their physical activity.

　　D．The minority of children were not studied at all.

　　22．The passage is intended to________．accelerometers during exercise

　　D．advise parents to keep in touch with their children
