27、al until adequate orientation and mobility 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【C2】_ situations or obstacles to avoid.Orientation refers to the【C
28、3】_ map one has of ones surroundings and to the relationship between self and that environment. It is best generated by moving through the environment and【C4】_ together relationships, object by object, in an organized approach. With【C5】_ visual feedback to reinforce this map, a visually impaired per
29、son must rely on memory for key landmarks and other clues, which enable visually impaired persons to【C6】_ their position in space.Mobility is the ability to travel safely and efficiently from one point to another within ones physical and social environment. Good orientation skills are necessary to g
30、ood mobility skills. Once visually impaired students learn to travel safely as pedestrians (行人), they also need to learn to use public transportation to become as【C7】_ as possible.To meet the【C8 】_ demands of the visually impaired person, there is a sequence instruction that begins during the presch
31、ool years and may continue after high schools. 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【C9】_ , such as inside or outside, in fron

34、10 】（A）comfortable（B） effective（C） efficient（D）efficacious二、Part Reading Comprehension60 Any scientist who is not a hypocrite will admit the important part that luck plays in scientific discovery. Our estimate of the importance of luck is inherently biased: we know when we benefit from luck, but in
35、the nature of things cannot assess how often bad luck deprives us of the chance of making what might have been an important discovery.A colleague and I carried out an experiment in which little tissue fragments, which were very difficult to work with, were injected into mice of different strains. If
36、 we had been more experienced, we would have injected only white blood cells (which would have been easier to handle) into the mice. We now know that if we had done this, we would not have discovered actively acquired tolerance because the grafts would have in effect rejected their hosts. Obviously,
37、 we were lucky, but our scientific training enabled us to recognize the significance of the accident. I think, therefore, that there was no need for the distinguished neu-rophysiologist Hodgkin to refer to his “feeling of guilt about suppressing the part which chance and good fortune played in what
38、now seems to be a rather logical development.“It might nevertheless seem as if luck plays a dominant role in scientific discovery. I would like to challenge this view for the following reasons; we sometimes describe as “lucky“ a person who wins a prize in a lottery at long odds; but if we describe t
39、he accidental discovery on a park bench of a lottery ticket that turns out to be the winning one?The two cases are quite different. A person who buys a lottery ticket is putting himself or herself in the way of winning a prize. This individual has, so to speak, purchased candidacy for such a turn of
40、 events and all the rest is a matter of mathematical probabilities. So it is with scientists. A scientist is anyone who, by observations and experiments conducted, by the literature read, and even by the company kept, puts himself or herself in the way of making a discovery. These individuals, by de
41、liberate action, have enormously enlarged their awarenesstheir candidacy for good fortuneand will not take into account evidence of a kind that a beginner or a casual observer would probably overlook or misinterpret. I honestly do not think that blind luck of the kind enjoyed by someone who finds a
42、winning lottery ticket for which he or she has not paid plays an important part in science or that many important discoveries arise from the casual intersection of two lines.Nearly all successful scientists have emphasized the importance of preparedness of mind, and I want to emphasize that this pre
43、paredness of mind is worked for and paid for by a great deal of exertion and reflection. If these exertions lead to a discovery, then I think it would be inappropriate to credit such a discovery to luck.61 The outcome of the experiment described in Lines 1 -4 (Para.2) suggests that_.（A）luck worked a
44、gainst the scientists at first（B） the injection of only white blood cells into the mice allowed the two scientists to make the discovery（C） the mice represented the perfect animals on which to conduct the experiment（D）the scientists involved were able to capitalize on luck62 The word “deliberate“ (L
45、ine 5, Para.4)is closest to _in meaning.（A）cunning（B） compelling（C） cautious（D）intentional63 The author implies that a scientist achieves “candidacy for good fortune“ (Line 6, Para. 4) by_.（A）making careful and repeated mathematical calculations（B） playing hunches rather than depending on research（C
46、） performing enough experiments to increase the statistical probability of success（D）obtaining knowledge that allows him or her to recognize important evidence64 The meaning of the phrase “casual intersection of two lines“ (Last sentence, Para. 4) is most clearly conveyed by which of the following?（
47、A）Informal kinds of experiments.（B） Two detailed plans.（C） Geometrically precise experiments.（D）Unanticipated coincidence.65 The primary purpose of the passage is to_.（A）delineate a single definition of luck（B） show that scientists discover what they intend to find（C） compare science to a game（D）sha
48、re the pleasure in making scientific discoveries65 Edna was not in the least surprised by my offer. I hitched the traveling-can containing the food on to the carrier. I didnt want to ride on the rough approach to the house so I rolled the bicycle the short distance from the house to the mad while Ed
49、na walked beside me. Mounting the vehicle with the can on the back and Edna on the cross-bar proved a little tricky, I solved the problem by getting on the seat first and keeping the bicycle stationary with one foot resting firmly on the ground. Then Edna climbed on the bar sitting sideways; and I pushed off. The excitement of having her so close within my arms and the perfume of her hair in my nose would have proved overpowering if I
