【题目】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 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.

【1】What does the underlined word “critical” mean in the first paragraph?

A. Serious. B. Disapproving.

C. Significant. D. Criticizing.

【2】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.

【3】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.

【4】 Where can you most probably find the passage?

A. In a science magazine. B. In a storybook.

C. In a textbook . D. In a book review.

【题目】Juac has made the leap from being an African refugee (难民) to a chess champion in the United States. His job is to share his expertise(专长) with students in schools, chess camps and other events.

During Sudan's civil war in the mid-1980s, Juac was forced out of the country with 20,000 0ther so -called Lost Boys. He fled to Ethiopia, then to Kenya staying in a refugee camp for eight years, where he learned to play chess.

Juac described a dangerous journey in which half the boys didn't survive. To eat, they had to kill wild animals.

"There were animals on the way. It was about a thousand miles and sometimes there was no water. When we were in Ethiopia, we had to cross the river and there a lot drowned."

Juac arrived in the United States in 2004 and began working as a security guard. Winning a chess tournament gave him this teaching opportunity. Juac believes chess helps prepare young people for life.

"Some kids are not interested, so it's your job to make them like the game, to explain them what chess is going to help them with." He said. "Like, I can tell, this game will give you patience, and help with your math skills."

Julie Cathone, a second grade teacher in Jackson Public School, agrees. The School's principal, Meghan Kelley, said Juac and chess have made a big difference.

"What a role model. I mean when you think about just overcoming, and finding what you love and turning that into your life's work."

Juac said he enjoys the freedom he has in the United States. But his passion is playing and teaching chess to youngsters. His boss, Michael Propper , said Juac has one great advantage.

"I think he's believable. I think they look at him and he's so unassuming that they feel like they can do what he's doing and be a person as he is too."

Ju ac still has a big goal ahead of him-becoming an international chess master. With his skill and patience, Propper and his peers have no doubt that will happen.

【1How long did Juac most probably stay in Ethiopia?

A. About six years. B. About eight years.

C. About twelve years. D. About sixteen years.

【2】We can learn from the passage that Juac _

A. must be teaching kids chess for free

B. is patient and good at math problems

C. surely has his own chess school in American

D. hasn't taken part in international chess contests

【3The underlined word "unassuming" probably means __

A. not appear important B. seem to be very great

C. appear very charming D. be not strict or serious

【4】Which is the best title for this passage?

A. "Lost Boys" Experienced Difficult Times.

B. Former Sudan "Lost Boy" Appears in NYC.

C. Former Sudan “Lost Boy" Becomes Chess Master.

D. African Boy Is Teaching Chess in the United States.

【题目】Will it matter if you don’t take your breakfast? A short time ago, a test was given in the United States. People of different ages, from 12 to 83, were asked to have a test. During the test, these people were given all kinds of breakfast, and sometimes they got no breakfast at all. Scientists wanted to see how well their bodies worked when they had eaten different kinds of breakfast.

The results show that if a person eats a right breakfast, he or she will work better than if he or she has no breakfast. If a student has fruit, eggs, bread and milk before going to school, he or she will learn more quickly and listen more carefully in class. The result is opposite to what some people think. Having no breakfast will not help you lose weight. This is because people become so hungry at noon that they eat too much for lunch. They will gain weight instead of losing it. You will lose more weight if you reduce your other meals.

【1During the test, the people were given ________.

A. no breakfast at all

B. very rich breakfast

C. different foods or sometimes none

D. little food for breakfast

【2The results show that ________.

A. breakfast has little to do with a person’s work

B. breakfast has great effect (影响) on work and studies

C. a person will work better if he only has fruit and milk

D. girl students should have less for breakfast

【3According to the passage, some people think that if you don’t have breakfast, you will __________.

A. be healthier B. work better

C. lose weight D. fail the test

【4】The word “reduce” in the last sentence means _________ .

A. 减少 B. 增加 C. 放弃 D. 享用
