问题     Visual impairment(视觉障碍)carries with it a reduced or restricted ability to travel through one’s physical and social environment until adequate orientation(定方位)and mobility(移动)skills have been established. Because observational skills are more limited, self-control within the immediate surroundings is limited. The visually impaired person is less able to anticipate hazardous situations or obstacles to avoid.
    Orientation refers to the mental map one has of one’s surrounding and to the relationship between self and that environment. The mental map is best generated by moving through the environment and piecing together relationships, object by object, in an organized approach. With little or no visual feedback to reinforce this mental map, a visually impaired person must rely on memory for key landmarks and other clues. Landmarks and clues enable visually impaired persons to affirm their position in space.
    Mobility, on the other hand, is the ability to travel safely and efficiently from one point to another within one’s physical and social environment. Good orientation skills are necessary to good mobility skills. Once visually impaired students learn to travel safely as pedestrians(f?A)they also need to learn to use public transportation to become as independent as possible.
    To meet the expanding needs and demands of the visually impaired person, there is a sequence of instruction that begins during the preschool years and may continue after high school. Many visually impaired children lack adequate concepts regarding time and space or objects and events in their environment. During the early years much attention is focused on the development of some fundamental concepts, such as inside or outside, in front of or behind, fast or slow movement of traffic, the variety or intersections, elevators or escalators, and so forth. These concepts are essential to safe, efficient travel through familiar and unfamiliar settings, first within buildings, then in residential neighborhoods, and finally in business communities.
In the passage, the author insists that______.
选项 A、visually, impaired children go to school for survival
B、the needs and demands of visually impair children expand
C、visually impaired children acquire the fundamental concepts for safe mobility
D、preschool children receive the instruction in the concepts of time and space or objects and events
答案C
解析 文章最后一段作者主要讲到了针对视觉障碍儿童的定位和移动问题，制订了一系列的教育计划。其中“During the early years much attention is focused on the development of some fundamental concepts，such as inside or outside．．．”在早期阶段，更多的注意力应该集中在一些基础概念的培养上，比如里或外等方面。由此可以看出作者对培养视觉障碍儿童安全移动的基础概念的重视。因此C项的内容即为作者要强调的内容。所以本题的正确答案为C。
