问题     Videodisc holds great promise of helping to meet the needs of American schoolchildren who have problems seeing, hearing, speaking, or socializing. Almost eleven percent of the students aged 3-21 in this country have an impairment that affects their ability to benefit from a regular education program. Handicapped students require special education because they are often markedly different from most children in one or more of the following ways: mentally retarded (发展迟缓的), learning-disabled, emotionally disturbed, deaf visually handicapped, physically handicapped, or other health impairments. The education of these handicapped children is rewarding but challenging.
    A special education student usually needs a longer period of time to acquire information. Repetitive teaching techniques arc often beneficial, and indefatigable(孜孜不倦的) consistency on the part of the teacher is frequently necessary. Interactive videodisc courseware has characteristics that can be capitalized upon to meet the challenges that special education poses. A videodisc program is infinitely patient. Repetition of any videodisc lesson can continue endlessly, and designers can assure absolute consistency within a program. Most important, according to special educator William Healey of the University of Arizona, is that videodisc "adds an extra dimension of realism for children who need graphic representations".
    Healey explained that deaf and mentally retarded children especially have difficulty grasping figurative (比喻的) language and higher-order language concepts. He believes that for special education, the power of videodisc lies in the ability of the technology to visually represent language concepts normally taken for granted by non-handicapped persons. Complex figurative language forms such as idioms and metaphors come most readily to mind as being difficult for handicapped learners.
A videodisc courseware is beneficial to those who have study difficulties because _______.
选项 A、its fancy design is very attractive
B、it allows the user to go back to where he wants to restudy
C、the content of it is healthy and promising
D、it is developed by university professors
答案B
解析 推断题。文章第二段第二句指出，残疾儿童往往需要老师不厌其烦地反复教导，接着谈到互动式影碟课件可以不断地重放课程，由此推断，影碟课件使学习有困难的学生能够回放他们想再次学习的课程，故选B。
