Tension and anxiety are obstacles（障碍）to effective learning.The ability to relax is just as important to success in school as the ability to read.Anxiety can cause students to forget chapters that they have read,to “go blank” at quiz time,or to fail to meet deadlines and to complete assignments on schedule（按时）.Anyone can learn to rid（使摆脱）himself or herself of tension by resting the body,breathing deeply,and relaxing for three or four minutes before a test.Attention to details such as outlining（写提纲）,note-taking,and time scheduling will help free mental energy to work on the tasks of learning.Planning one day ahead on a pocket calendar will do as much to improve the grades of some students in memory or speed-reading courses.
