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 io travel safely as pedestrians(行人) 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.

Questions 6I to 65 are based on the following passage.
Our bodies are wonderfully skilful at maintaining balance. When the temperature jumps, we sweat to cool down. When our blood pressure falls, our hearts pound to compensate. As it turned out, though, our natural state is not a steady one .Researchers are finding that everything from blood pressure to brain function varies rhythmically with the cycles of sun, moon and seasons. And their insights are yielding new strategies for keeping sway such common killers as heart disease and cancer. only one doctor in 20 has a good knowledge of the growing field of“chronotherapeutics,” the strategic use of time (chronos) in medicine. But according to a new American Medical Association poll, three out of four are eager to change that “The field is exploding", says Michael Smolensky. “Doctors used to look at us like, ‘What space ship did you guys get off of?’ Now they’re thirsty to know more." |
