There are two kinds of physical activity which require special training. The first demands exact careful movements of the muscles. This kind of activity must be strictly controlled because even a slight movement in the wrong direction will lead a mistake. To type quickly, for example, a person needs training; the slightest movement of a finger in the wrong direction may cause a spelling mistake. A dancer who has to dance on the point of her shoes or turn around on one foot must be trained for a long period of time before she can sense her own center and balance herself. You may have seen a girl walking on a rope across an empty space, which, too, requires a lot of practice.

The second kind of physical activity needs greater strength or extra effort. Most of us get tired if we try to run half a mile without stopping, but a specially-trained person can do this without much effort. Three years ago, some scientists carried out experiments, which produced meaningful and unexpected results. They wanted to find out whether a certain amount of physical exercise would injure those suffering from heart problems. They selected some male patients and trained them in continuous bicycle riding. They were surprised to find that the harmful effect of given amount of physical effort was actually less on the hearts of these trained patients than on those of the patients who were not similarly trained. This is important because it shows that regular physical exercise enables us to make better use of the oxygen we breathe in and that this training, in fact, reduces the amount of work our hearts do. Many tasks which are hard for untrained people are not hard at all for trained people.

The first kind of physical activity must be strictly controlled because _________.

A．a mistake in the wrong direction is dangerous to the fingers

B．a wrong movement in a direction will cause no mistakes

C．a movement in the wrong direction will cause a mistake

D．a slight movement of a finger will lead to a mistake

What must a dancer do before she can balance herself?

A．She must dance on the point of her shoes.

B．She must receive long-time training.

A．some male patients were asked to ride bicycles regularly in the experiments

B．the physical exercise had more harmful effect on the hearts of the untrained patients

C．the physical exercise was harmless to the male patients with heart trouble

D．the physical exercise could be helpful for the patients to take in more oxygen

A Charlotte, N.C., man was charged with first-degree murder of a 79-year-old woman whom police said he scared to death. In an attempt to evade policemen after a bank robbery, the Associated Press reports that 20-year-old Larry Whitfield broke into the home of Mary Parnell. Police say he didn’t touch Parnell but that she died after suffering a heart attack that was caused by terror. Can the guy be held responsible for the woman’s death? Prosecutors(公诉人) said that he can under the state’s murder rule, which allows someone to be charged with murder if he or she causes another person’s death while committing or fleeing from a severe crime like robbery—even if he or she doesn’t kill someone on purpose.

But, medically speaking, can someone actually be frightened to death? We asked Martin Samuels, chairman of the neurology department at Brigham and Women’s Hospital in Boston.

Absolutely, no question about it.

The body has a natural protective method called the fight-or-flight response(战或逃反应), which was originally described by Walter Cannon，the chairman of Harvard University’s physiology department from 1906 to 1942. If, in the wild, an animal is faced with a life-threatening situation, the autonomic nervous system responds by increasing heart rate, increasing blood flow to the muscles, and slowing digestion, among other things. All of this increases the chances of succeeding in a fight or running away from an aggressive beast. This process certainly would be of help to primitive humans. However, in the modern world there is obvious decline of the fight-or-flight response.

The autonomic nervous system uses the chemical messenger to send signals to various parts of the body to activate the fight-or-flight response. This chemical is toxic in large amounts; it damages the organs such as the heart, lungs, liver and kidneys. It is believed that almost all sudden deaths are caused by damage to the heart. There is almost no other organ that would fail so fast as to cause sudden death. Kidney failure, liver failure, those things don’t kill you suddenly.

By the way, any strong positive or negative emotions such as happiness or sadness can cause the same result. There are people who have died in intercourse or in religious passion. There was a case of a golfer who hit a hole in one, turned to his partner and said, “I can die now”, and then he dropped dead. For about seven days after the 9/11 terrorist attacks on the World Trade Center and Pentagon there was an increase of sudden cardiac death among New Yorkers.

Why the Charlotte, N.C., man was charged?

A. Because he threatened the policemen to kill an old woman.

B. Because he caused an old woman’s terror and she died.

C. Because he beat an old woman and caused her heart attack

D. Because he murdered an old woman while robbing a bank.

What is Martin Samuels’ attitude to the possibility of being frightened to death?

A. Approval. B. Disapproval. C. Doubtful. D. Indifferent.

Which of the following about the fight-or-flight response is true?

A. The fight-or-flight response was raised and proved by Martin A. Samuels.

B. It is a natural protective method that can’t be found in all creatures but humans.

C. The ancient humans had a superior fight-or-flight response than modern ones.

D. The fight-or-flight response is beneficial to both our actions and organs.

What activity can we infer is less likely to damage the organs?

A. Winning a big lottery. B. Missing a dead family.

C. Watching a horror movie. D. Listening to a sweet song.

The purpose of the passage is_________.

A. to explain why people will die of a heart attack

B. to offer some advice on protecting us from heart failure

C. to compare different kinds of feelings to cause a death

D. to show strong emotions can cause a sudden death

Skateboarding has become one of several non - traditional activities that PE teachers around America are introducing to inspire kids to exercise regularly. Some PE classes feature in-line (滚轮) skating, yoga, and even rock climbing. Experts have called those types of activities “the new PE”.
Such activities are part of a larger effort to help kids develop lifelong fitness habits and to keep them from becoming overweight. Now, 9 million U.S. children and teens are overweight. Obesity (肥胖) can lead to health problems such as diabetes and heart disease later in life.
“Our children and youth are becoming unhealthy and obese,” says Lindsey Johnson. “Skateboarding is a great activity that keeps kids doing physical movement and gives them new skills and interest.”
Some schools don’t allow skateboarding because they say it is dangerous. Cendali, however, argues that regular practice eliminates a great deal of the danger. “We teach students how to do it and how to do it safely,” he says.
Some people say skateboarding teaches life lessons. “Skateboarding teaches kids to believe that if they stick with something they will finally succeed,” says education expert Richard Sagor of Lewis & Clark College in Portland, Oregon.
Skateboarding inspires kids not to give up in learning difficult skills. “It’s natural for kids to want to learn and get better at things,” adds Sagor. “When it comes to skateboarding, they’ll try a trick hundreds of times before they succeed.” That same effort could be made in schoolwork.
Eric Klassen agrees that skateboarding requires kids to stop saying a task is too hard for them. “A baby will attempt to walk 600 to 900 times before he or she is successful,” says Klassen. “We tell students that they shouldn’t say ‘I can’t do it’ unless they’ve tried 600 to 900 times.”
【小题1】Skateboarding is introduced into American schools to ______.

A．encourage students to compete bravely in competition

B．teach students how to deal with risks

C．prevent students suffering from heart disease later in life

D．help students form the habit of doing sports

【小题2】The underlined word “eliminates” in Paragraph 4 probably means “______”.

【小题3】What life lesson do kids learn from skateboarding?

A．To succeed in life you have to learn skateboarding.

B．You will succeed in life if you don’t give up.

C．Only after failing 600 to 900 times can you succeed.

D．There is no hard work after learning skate-boarding well.

【小题4】What would be the best title for the passage?

A．The dangerous PE	B．Skills of skateboarding
C．The new PE	D．The change of PE

If music makes you smarter and exercise helps you to think, surely exercising to music can turn you into an intelligent person.

A team of scientists from Ohio State University did experiments on 33 volunteers who were getting better from heart disease following operation. They found that people who exercised while listening to Italian musician Antonio Vivaldi’s “The Four Seasons” did much better on language ability tests than without music.

“Facts suggest that exercise improves the learning ability of people with heart disease,” said the psychologist Charles Emery, who led the study. “And listening to music is thought to enhance understanding. We just wanted to put the two results together,” he added.

The volunteers said they felt better emotionally and physically after working out with or without the music. But their improvement on the test doubled after listening to music during exercise. Scientists have proved that music can be good for health, education and well-being. It helps reduce stress, sadness and nervousness; encourages relaxation or sleep; wakes up the body and improves memory and thoughts.

In medical fields, music is used widely for patients who have had head hurts before and after operation. “The Four Seasons” was used because of its moderate tempo（舒缓的节拍）and positive results in earlier research. “Exercise seems to cause positive changes in the nervous system(神经系统) and these changes may have a direct result on learning ability,” Emery said.

Scientists have been studying the results of music on understanding since the early 1950s. By 2000, psychologists were using Mozart’s music, especially his violin pieces, to help children with speech disorders. Mozart was chosen because his music is not overexciting and has clear structures. A study showed students who listened to Mozart went on to score higher marks in an intelligence test. With important exams drawing near, your parents will not probably allow you to listen to music. But perhaps now you have good reasons to argue with them.

1.The underlined word enhance can be replaced by ______.

A．impress B．improve C．provide D．produce

2.The text mainly tells us that _____.

A．music and exercise lead to relaxation or sleep

B．33 volunteers work on music in medical fields

C．exercising to music makes people healthy and bright

D．scientists give suggestions on choosing music to exercise to

3.It can be learned from the last paragraph that ______.

A．you are supposed to follow your parents’ words

B．students should not listen to music before exams

C．you have some good reasons to exercise to music

D．music might help you to get higher grades in tests

4.Which of the following statements is true?

A．Exercise seems to cause negative changes without music.

B．Exercise reminds people with head hurts of what they’ve learned.

C．Scientists often use Mozart’s music, for it is not too exciting.

D．“The Four Seasons” is used to help children with speech disorders.
