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.
The word "impairment" ( Line 2, Para. 1 ) probably means _______.
选项 A、habit
B、disability
C、misconception
D、belief
答案B
解析 语义题。文章第一段第二句的大意是“在该国3至21岁的学生中，约有11%的学生有_____ 从而影响了他们接受常规教育的能力。”habit意为“习惯”，disability意为“残疾”，misconception意为“误解”， belief；意为“信仰”，由句意可知B正确。
