Questions 51 to 55 are based on the following passage.
    Learning disabilities are very common. They affect perhaps 10 percent of all children. Four times as many boys as girls have learning disabilities
Since about 1970, new research has helped brain scientists understand these problems better. Scientists now know there are many different kinds of learning disabilities and that they are caused by many different things. There is no longer any question that all learning disabilities result from differences in the way the brain is organized.
    You cannot look at a child and tell if he or she has a learning disability. There is no outward sign of the disorder. So some researchers began looking at the brain itself to learn what might be wrong.
    In one study, researchers examined the brain of a learning-disabled person, who had died in an accident. They found two unusual things. One involved cells in the left side of the brain, which control language. These cells normally are white. In the learning disabled person, however, these cells were gray. The researchers also found that many of the nerve cells were not in a line the way they should have been. The nerve cells were mixed together.
    The study was carried out under the guidance of Norman Geschwind, an early expert on learning disabilities. Doctor Geschwind proposed that learning disabilities resulted mainly from problems in the left side of the brain. He believed this side of the brain failed to develop normally. probably, he said, nerve cells there did not connect as they should. So the brain was like an electrical device in which the wires were crossed.
    Other researchers did not examine brain tissue. Instead, they measured the brain's electrical activity and made a map of the electrical signals.
Frank Duffy experimented with this technique at Children's Hospital Medical Center in Boston. Doctor Duffy found large differences in the brain activity of normal children and those with reading problems. The differences appeared throughout the brain. Doctor Duffy said his research is evidence that reading disabilities involve damage to a wide area of the brain, not just the left side.

51. Scientists found that the brain cells of a learning-disabled person differ from those of a normal person in ________.
A) structure and function
B) color and function
C) size and arrangement
D) color and arrangement .

52. Which of the following is NOT mentioned in the passage?
A) Learning disabilities may result from the unknown area of the brain .
B) Learning disabilities may result from damage to a wide area of the brain .
C) Learning disabilities may result from abnormal organization of brain cells.
D) Learning disabilities may result from problems in the left side of the brain.

53 . All of the following statements are true EXCEPT that ________.
A) many factors account for learning disorder
B) a learning disabled person shows no outward signs
C) reading disabilities are a common problem that affects 10 percent of the population
D) the brain activity of learning disabled children is different from that of normal children

54. Doctor Duffy believed that ________.
A) he found the exact cause of learning disabilities
B) the problem of learning disabilities was not limited to the left side of the brain
C) the problem of learning disabilities resulted from the left side of the brain
D) the problem of learning disabilities did not lie in the left side of the brain

55. According to the passage we can conclude that further researches should be made ________.
A) to investigate possible influences on brain development and organization
B) to study, how children learn to read and write, and use numbers
C) to help learning disabled children to develop their intelligence
D) to explore how the left side of the brain functions in language learning

Questions 56 to 60 are based on the following passage.
    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 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 hazardous situations or obstacles to avoid.
    Orientation refers to the mental map one has of one's surroundings 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 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.

56. flow can we increase the visually impaired person's ability to travel through his physical and social environment?
A) By helping him develop adequate orientation and mobility skills .
B) By teaching him to learn observational skills.
C) By warning him of hazardous situations or obstacles.
D) By improving his visual ability.

57. The visually impaired person's position in space ________.
A) is not determined by memory but by physical landmarks and clues
B) is located in relation to other items in his mental map
C) enables him to construct the mental map
D) reinforces the mental map of his surroundings

58. Mobility skills which the visually impaired person is learning refer to the ability ________.
A) to travel as a dependent tourist
B) to travel as a pedestrian and a passenger
C) to travel as a pedestrian with a company
D) to travel within the safe physical and social environment

59. In the passage, the author insists that ________.
A) visually impaired children go to school for survival
B) the needs and demands of visually impaired 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

60. What is the author mainly talking about in the passage?
A) Visual impairment and memory.
B) The visually impaired person's physical and social environment.
C) Mental development of the visually impaired person.
D) Orientation and mobility of the visually impaired person.

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."
    In medical school ,most doctors learn school, most doctors learn that people with chronic conditions should take their medicine at steady rates. “It's a terrible way to treat disease," says Dr. Richard Martin. For example, asthmatics( 气喘患者)are most likely to suffer during the night. Yet most patients strive to keep a constant level of medicine in their blood day and night, whether by breathing in on an inhaler(吸入器) four times a day or taking a pill each morning and evening. In recent studies, researchers have found that a large midafternoon dose of a bronchodilator(支气管扩张剂) can be as safe as several small doses, and better for preventing nighttime attacks
    If the night belongs to asthma, the dawn belongs to high blood pressure and heart disease. Heart attacks twice as common at 9 a.m as at 11 p.m part of the reason is that our blood pressure falls predictably at night, then Peaks as we start to work for the day. “Doctors know that”, says Dr. Henry Black of Chicago Medical Center, “but until now, we haven't been able to do anything about it." Most blood pressure drugs provide 18 to 20 hours of relief. But because they're taken in the morning, they're least effective when most needed. “You take your pill at 7and it's working by 9,”says Dr. William White of the University of Connecticut Health Center. “But by that time you've gone through the worst four hours of the day with no protection ,” Bedtime dosing would prevent that lapse ,but it would also push blood Pressure to dangerously low levels during the night.
