Anyone who has worn a cast (石膏) knows that rebuilding muscle strength once the cast is removed can be difficult. Now researchers at the Ohio Musculoskeletal and Neurological Institute (OMNI) at Ohio University have found that the mind is critical in maintaining muscle strength following a long period of not moving and that mental imagination may be key in reducing the associated muscle loss.
Strength is controlled by a number of factors----the most studied by far is skeletal muscle. However, the nervous system is also an important, though not fully understood, determining factor of strength and weakness. Brian C. Clark and colleagues set out to test how the system functions in strength development. They designed an experiment to measure changes in wrist (腕) muscle strength in three groups of healthy adults. Twenty-nine
B. Favorable.
C. Regretful.
D.
subjects wore a hard cast that extended from just below the elbow (肘) past the fingers, effectively preventing the hand and wrist from moving, for four weeks. Fifteen subjects who did not wear casts served as the control group.
Of the 29 people wearing a hard cast, half were asked to regularly perform an exercise, imagining they were strongly contracting their wrist for five seconds and then resting for five seconds. This was repeated four times in a row followed by a one-minute break for a total of 13 rounds per session and five sessions per week. The other half performed no imagination exercises.
At the end of the four-week experiment, both groups who wore casts had lost strength in their unmoving limbs (肢体) when compared to the control group. But the group that performed imagination exercises lost 50% less strength than the non-imagination group. The nervous system’s ability to fully make the muscle recover also returned more quickly in the imagination group compared to the non-imagination group.
51. What does the underlined word “critical” mean in the first paragraph? A. Serious.
B. Disapproving.
C. Significant.
D. Criticizing.
52. Which of the following statements is NOT true according to the passage? A. Scientists have partly understood the nervous system.
B. Whoever has worn a cast for long may have difficulty in muscle recovery.
C. Scientists have already spent a lot of time in studying skeletal
muscle.
D. The number of the subjects in the experiment was 29 in all. 53. How many rounds of exercise were performed in the four-week experiment? A. 13.
B. 65.
C. 260.
D.1040.
54. What can we learn from the experiment?
A. The control group lost 50% less strength than the non-imagination group.
B. The imagination group lost more strength than the non-imagination group.
C. The control group wore casts but didn’t perform the imagination exercise.
D. The speed of non-imagination group’s muscle recovery was slower. 55. Where can you most probably find the passage? A. In a science magazine. C. In a textbook .
B. In a storybook.
D. In a book review.

Before he sailed round the world single-handed, Francis Chichester had already surprised his friends several times. He had tried to fly round the world but failed. That was in 1931.
The years passed. He gave up flying and began sailing. He enjoyed it greatly. Chichester was already 58 years old when he won the first solo trans-Atlantic sailing race. His old dream of going round the world came
back, but this time he would sail. His friends and doctors did not think he could do it, as he had lung cancer. But Chichester was determined to carry out his plan. In August, 1966, at the age of nearly 65, an age at which many men retire, he began his greatest voyage of his life. Chichester covered 14,100 miles before stopping in Sydney, Australia. This was more than twice the distance anyone had previously sailed alone. On shore, he could not walk without help. Everybody said the same thing: he had done enough; he must not go any further. But he did not listen. After resting in Sydney for a few weeks, Chichester set off once more in spite of his friends’ attempt to dissuade him. The second half of his voyage was by far the more dangerous part, during which he sailed round the risky Cape Horn. After succeeding in sailing round Cape Horn, Chichester sent the following radio message to London:“I feel as if I had waken up from a horrible dream. Even a wild horse could not drag me down to Cape Horn and that rough Southern Ocean again.”
Just before 9 o’clock on Sunday evening 28 May, 1967, he arrived back in England, where a quarter of a million people were waiting to welcome him. The whole voyage from England and back had covered 28,500 miles. It had taken him nine months, of which the sailing time was 226 days. He had done what he wanted to accomplish.
56. What is the main idea of the passage? (No more than 10 words) 57. What did Chichester achieve at the age of 58?(No more than 10 words) 58. The underlined word “dissuade” in Paragraph 4 can be replaced by _______.(One word)
