第一部分 选修七 Module 3-4 Ⅰ.阅读理解 (2015·湖北高三八校二模) Dyslexia is a learning disorder. It interferes with the ability to recognize words, and for some readers to understand what they have read. Experts say dyslexia affects about five to ten percent of the population of the United States. Researchers have long known that people with dyslexia write or read words and letters backwards in the wrong order. But a new study shows that people with dyslexia may have trouble redirecting their attention between senses, from seeing something to hearing something. The study suggests something that might help dyslexic people learn more quickly—play video games. Vanessa Harrar of Britain's University of Oxford led the study. She reported the findings in the journal Current Biology. The study suggests that dyslexic people may have trouble moving quickly from what they read to what they hear. In the study, Doctor Harrar tested 17 people with dyslexia, and 19 others without reading problems. The volunteers were asked to push a button as quickly as possible when they heard a sound, saw a light or experienced both together. Doctor Harrar compared the speed of their reactions. She found that people with dyslexia were just as fast as the others when they saw only a picture or heard only a sound. But the Dyslexics had a slower reaction time when they heard a sound and saw a picture at the same time, this may have an effect on how dyslexic children are taught how to read. |
