Magnetic interference from MP3 headphones can interfere with heart pacemakers （心脏起搏器）and implantable defibrillators, a study has found.

Heart patients with such devices should not put their headphones in their breast pocket or hang them round their neck, researchers have warned.

Small but strong magents inside headphones can deactivate the devices if placed within 1.2 inches of them, posing a real risk to the patient, researchers told an American Heart Association meeting in New Orleans. The MP3 players themselves posed no threat to pacemakers and defibrillators.

Dr. William Maisel of the Medical Device Safety Institute at Beth Israel Medical Center in Boston led a team that tested eight models of MP3 player headphones, including clip-on and ear bud types, in 60 defibrillator and pacemaker patients. They placed the headphones on the patients' chests, directly over the devices. The headphones interfered with the heart devices in about a quarter of the patients and interference was twice as likely in those with a defibrillator than with a pacemaker.

A pacemaker sends electrical impulses to the heart to speed up or slow cardiac rhythm. The magnet, however, could make it deliver a signal no matter what the heart rate is, possibly leading to palpitations or arrhythmia, the researchers said.

An implantable defibrillator signals the heart to normalize its rhythm if it gets too fast or slow. A magnet could de-activate it, making it ignore an abnormal heart rhythm instead of delivering an electrical shock to normalize it. The devices usually go back to working the right way after the headphones are removed, the researchers said.

"The main message here is: it's fine for patients to use their headphones normally, meaning they can listen to music and keep the headphones in their ears. But what they should not do is put the headphones near their device," Dr Maisel said.

72. The underlined word deadactive in the third paragraoh probably means “to make something_______”

A. incorrect     B. normal      C. ineffective        D. useful

73. According to the study, what is actually endangering heart patients with heart devices?

    A. The music they hear with MP3 headphones

B. The eight models of MP3 players that have been tested.

C. Magnetic interference from MP3 headphones.

D. The magnets inside pacemakers and defibrillators.

74. What is the fourth paragraph about ?

A. Atest to monitor how heart beats are interfered with.

B. How many patients were tested 

C. A brief introduction to defibrillators and pacemakers .

D. Dr. William Maisel was concerned about heart problems.

75. From the passage we can learn that________.

A. MP3 players are gaining popularity among heart patients

B. pacemakers and defibrillators are actually harmful to people’s health

C. heart patients should not listen to music.

D. pacemakers and defibrillators can help normalize heart rhythm

It is love that makes the world go round. And it is also love that has such power to overcome all difficulties. So we say: “Love will find a way.” As smile is a facial expression showing pleasure, affection, and friendliness, it is the commonest way to show our good will perfectly without saying anything. A Chinese saying runs: “never hit a person who is smiling at you.” It is a time-proven fact that the smile is a language all its own— a universal language—understood by the people of every nation in the world. We may not speak the same tongue as our foreign neighbors, but we smile in the same tongue. We need no interpreter for thus expressing love, happiness, or good will.
One day while shopping in a small town in southern California, it was my misfortune to be approached by a clerk whose personality contradicted mine. He seemed most unfriendly and not at all concerned about my intended purchase. I bought nothing, and marched angrily out of the store. My anger toward that grew with each step. Outside, standing at the corner, was a dark-complexion young man in his early twenties. His expressive brown eyes met and held mine, and in the next instant a beautiful, dazzling smile covered his face. I gave in immediately. The magnetic power of that shining smile drove away all bitterness within me, and I found the muscles in my own face happily responding. “Beautiful day, isn’t it?” I remarked, in passing. The, suddenly something inside me sent me turning back. “I really owe you a debt of gratitude,” I said softly. His smile deepened, but he made no attempt to answer. A Mexican woman and two men were standing nearby. The woman stepped forward and eyed me inquiringly. “Carlos, he no speak English,” she volunteered. “You want I should tell him something?” In that moment I felt transformed. Carlos’ smile had made a big person of me. My friendliness and good will to ward all mankind stood ten feet tall. “Yes,” my reply was enthusiastic and sincere, “tell him I said ‘Thank you!’” “Thank you?” The woman seemed slightly puzzled. I gave her arm a friendly pat as I turned to leave. “Just tell him that,” I insisted. “He’ll understand. I am sure!” Oh, what a smile can do! Although I have never seen that young man again, I shall never forget the lesson he taught me that morning.
From that day on, I became smile – conscious, and I practice the diligently, anywhere and everywhere, with everybody. When I got excited in traffic, taking the right – of – way (公路用地) from the other car with my stupid mistake, I’d smile and shrug my shoulders apologetically. This action on my part would always draw a good – natured smile in return. If the other fellow was at fault – and if I could remember my resolution in time! – he’d get a broad smile of understanding. This took a bit of doing at first. I’ll admit it wasn’t always easy, but it was fun. The results were sometimes amazing. Many times, a broad, friendly smile would completely turn aside ill – feeling and tension. I’m wondering now how many tragic add dents could be avoided on our overcrowded highways, if every driver remembered to smile!

Like many of my generation, I have a weakness for hero worship. At some point, however, we all begin to question our heroes and our need for them. This leads us to ask: What is a hero?

Despite immense differences in cultures, heroes around the world generally share a number of characteristics that instruct and inspire people.

A hero does something worth talking about. A hero has a story of adventure to tell and community who will listen. But a hero goes beyond mere fame.

Heroes serve powers or principles larger than themselves. Like high-voltage transformers, heroes take the energy of higher powers and step it down so that it can be used by ordinary people.

The hero lives a life worthy of imitation. Those who imitate a genuine hero experience life with new depth, enthusiasm, and meaning. A sure test for would-be heroes is what or whom do they serve? What are they willing to live and die for? If the answer or evidence suggests they serve only their own fame, they may be famous persons but not heroes. Madonna and Michael Jackson are famous, but who would claim that their fans find life more abundant?

Heroes are catalysts (催化剂) for change. They have a vision from the mountaintop. They have the skill and the charm to move the masses. They create new possibilities. Without Gandhi, India might still be part of the British Empire. Without Rosa Parks and Martin Luther King, Jr., we might still have segregated (隔离的) buses, restaurants, and parks. It may be possible for large-scale change to occur without leaders with magnetic personalities, but the pace of change would be slow, the vision uncertain, and the committee meetings endless.

1.Although heroes may come from different cultures, they __________.

A．generally possess certain inspiring characteristics

B．probably share some weaknesses of ordinary people

C．are often influenced by previous generations

D．all unknowingly attract a large number of fans

2. According to the passage, heroes are compared to high-voltage transformers in that _______.

A．they have a vision from the mountaintop

B．they have warm feelings and emotions

C．they can serve as concrete examples of noble principles

D．they can make people feel stronger and more confident

3.Madonna and Michael Jackson are not considered heroes because __________.

A．they are popular only among certain groups of people

B．their performances do not improve their fans morally

C．their primary concern is their own financial interests

D．they are not clear about the principles they should follow

4.The author concludes that historical changes would __________.

A．be delayed without leaders with inspiring personal qualities

B．not happen without heroes making the necessary sacrifices

C．take place if there were heroes to lead the people

D．produce leaders with attractive personalities
