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.
According to Professor Healey, we may infer that mentally retarded children perhaps _______.
选项 A、need graphic representations in order to understand higher-order language concepts
B、are good at studying English idioms but often fail to grasp higher-order language concepts
C、are not very patient with videodisc which helps them to understand the world concepts
D、tend to be deaf as well and have difficulty learning the simple concept "before and after"
答案A
解析 推断题。文章第三段前两句指出，希利教授解释说耳聋和智力发展迟缓的孩子很难明白比喻性的话语和较为复杂的语言概念，所以他们需要直观的图解，而影碟课件能够帮助他们，由此推断A正确。
