Nothing can exceed the joy of discovering for yourself something that is important to you! It may be an idea or a bit of information you come across accidentally or a sudden understanding, 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 itbut no teacher can make the excitement or the joy happen. Thats up to you. A research paper, 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. 16According to the writer, personal discoveries in study _. Awill give one encouragement and directionBare helpful in finding the right informationCare the most valuable part of ones personal educationDwill help one to successfully complete school assignments17It can be inferred from the passage that writing a research paper gives one chances _. Ato fully develop ones personal abilitiesBto practice the skills learnt in the classroomCto prove that one is a productive writerDto show how well one can accomplish school assignments18From the context, the underlined word “encounters”(Para. 1) most probably means “_”. Ainterests BexperiencesCentertainments Dabilities19What will probably follow this passage?AHow to write a research paper. BThe importance of research in education. CHow to make new discoveries for oneself. DThe skill of putting pieces of information together. BCompared to adults, children seem to be moving constantly.So its no surprise that most parents who are quizzed about their childs 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 childs activity level, the vast majority80 percentdescribed 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 wasnt 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 childs 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.”20According to the Speedy Study what kind of children can be judged physically inactive?ASlim children.BChildren with less than an hour a day of physical activity.COverweight children.DChildren out of touch with their parents for a long time.21What does the writer probably mean by saying “a sizable minority of children were not” in Paragraph 3?AThe amount of childrens physical activity is far from the writers satisfaction.BA lot of children were not getting enough physical activity.CA small number of children didnt overestimate their physical activity.DThe minority of children were not studied at all.22The passage is intended to_Aencourage parents to fairly judge their childrens physical activity levelsBpersuade parents to keep an eye on their childrens weightCurge children to wear accelerometers during exerciseDadvise parents to keep in touch with their children111
