To be a good teacher, you need some of the gifts of a good actor; you must be able to hold the attention and interest of your students; you must be a clear speaker, with a good, strong, pleasing voice which is fully under you control; and you must be able to act what you are teaching, in order to make its meaning clear. Watch a good teacher, and you will see that he does not move motionless before his class; he stands the whole time he is teaching; he walks about, using his arms, hands and fingers to help him in his explanation, and his face to express his feeling. Listen to him, and you will hear the loudness, the quality and musical note of his voice always changing according to what he is talking about. The fact that a good teacher has some of the gifts of a good actor doesn't mean he will indeed be able to act well on the stage, for there are very important differences between the teacher's word and the actor's. The actor has to speak words which has been learnt by heart, he has1、A good teacher ______.A、knows how to hold the interest of his studentsB、must have a good voiceC、knows how to act on the stageD、stands or sits motionless while teaching2、In what way is a teacher''s work different from an actor''s?

共用题干Chest Compressions:Most Important of CPRCardiopulmonary resuscitation or CPR,can save the life of someone whose heart has stopped.The condition is called cardiac arrest.The heart stops pumping blood.The person stops breathing. Withoutlifesaving measures,the brain starts to die within four to six minutes.CPR combines breathing into the victim's mouth and repeated presses on the chest._________(46)However,a new Japanese study questions the usefulness of mouth-to-mouth breathing. The study waspublished in the British medical magazine,The Lancet. Doctors in Tokyo led the research.It examined more than four thousand people who had suffered cardiac arrest.In all the cases,witnesses saw the event happen.More than one thousand of the victims received some kind of medical assistance from witnesses.Seven hundred and twelve received CPR. Four hundred and thirty-nine received chest presses only._______(47) The researchers say any kind of CPR improved chances of the patient's survival.But,they said those people treated with only chest presses suffered less brain damage.Twenty-two percent survived with good brainability._________(48)The American Heart Association changed its guidelines for CPR chest presses in 2005._________(49)Gordon Ewy is a heart doctor at the University of Arizona College of Medicine in Tucson.He wrote a report that appeared with the study.Doctor Ewy thinks the CPR guidelines should be changed again.He said the heart association should remove rescue breaths from the guidelines.He argues that more witnesses to cardiac arrests would provide treatment if rescue breaths are not a part of CPR.He says this would save lives,_______(50)Cardiac arrest kills more than 300,000 people in the United States every year. The American HeartAssociation says about ninety-five percent of victims die before they get to a medical center._________（50）A:So far,we have not known exactly yet whether mouth-to一mouth breathing is really useless in CPR.B:Only ten percent of the victims treated with traditional CPR survived with good brain ability.C:CPR keeps blood and oxygen flowing to the heart and brain.D:His studies show that many people do not want to perform mouth-to-mouth breathing on a stranger for fearof getting a disease.E:It said neonle should increase the number of chest presses from fifteen to thirty for every two breaths given.F:No mouth-to-mouth rescue breaths were given to them.
共用题干Napping to a Healthier Heart?1 Researchers say they have developed a simple test that can tell if a person with heart disease is likely to suffer a heart attack.The test measures levels of a protein in the blood.The researchers say people with high levels of this protein are at high risk of heart attack,heart failure or stroke.2 Kirsten Bibbins-Domingo of the University of California in San Francisco led the team.For about four years,they studied almost one thousand patients with heart disease.The researchers tested the heart disease patients for a protein called NT-proBNP. Patients with the highest levels were nearly eight times more likely than those with the lowest levels to have a heart attack,heart failure or stroke.3 The researchers say the presence of high levels of the protein in the blood shows that the heart muscle is under pressure in some way.The study involved mostly men,so the researchers could not say for sure that the results are also true for women.They say the patients with the highest levels of NT-proBNP were older and had other problems like diabetes or high blood pressure.4 Other researchers say more studies are needed to confirm if knowing the protein levels of a heartdisease patient should affect that person’s treatment.They also would like to know if more aggressive treatment could reduce the patient's chance of a heart attack or stroke.The study appeared in theJournal of the American Medical Association.5 Could a little sleep during the middle of the day reduce the risk of a heart attack?An unrelatedstudy earlier this month in the Archives of Internal Medicine suggests that the answer may be yes.In countries like the United States,afternoon naps are mostly for children. But they are common for adults in Mediterranean countries.And these countries generally have lower rates of heart disease.So scientists in theUnited States and Greece wondered if naps could play a part.Twenty-three thousand healthy adults took part in the study by Harvard University and the University of Athens.Those who took thirty-minute naps three times a week had a thirty-seven percent lower risk of death from heart problems than people who did not takenaps.6 The researchers say napping may improve heart health by reducing stress.They say the researchsuggests that naps are especially good for working men.But they say not enough female subjects died during the study to judge the benefits for women.If a person has a high level of NT-proBNP_________.A: where fewer pepole die from heart problemB:whether they have the risk of heart attack,heart failure or stroke C:would probably have lower rates of heart diseaseD:how to test a person's NT-proBNP level in the blood by himselfE:his heart muscle would be under pressure in some wayF:that napping is of great benefit to women too

When did you last see a polar bear?On a trip to a zoo,perhaps?If you had attended a winter activity in New York a few years ago,you would have seen a whole polar bear club.These"Polar Bears"are people who-meet frequently in winter to swim in freezing cold water.That day,the air temperature was 3oC,and the water temperature was a bit higher.The members of the Polar Bear Club at Coney Island,New York are usually about the age of 60.Members must satisfy two requirements.First,they must get along well with everyone else in the group.This is very important because there are so many different kinds of people in the club.Polar Bears must also agree to swim outdoors at least twice a month from November through February.Doctors do not agree about the medical effects of cold-water swimming.Some are worried about the dangers of a condition in which the body′s temperature drops so low that finally the heart stops.Other doctors,however,point out that there is more danger of a heart attack during summer swimming because the difference between the air temperature and water temperature is much greater in summer than in winter.The Polar Bears themselves are satisfied with the benefits（or advantages）of cold-water swimming.They say that their favorite form of exercise is very good for the circulatory system（循环系统）because it forces the blood to move fast to keep the body warm.Cold-water swimmers usually turn bright red after a few minutes in the water.A person who turns blue probably has a very poor circulatory system and should not try cold-water swimming.The main benefits（or advantages）of cold-water swimming are probably mental.The Polar Bears love to swim year-round;they find it fun and relaxing.As one 70-year-old woman says,"When I go into the water,I pour my troubles into the ocean and let them float away."According to the passage,some doctors believe it is true thatA.you are healthy if cold-water swimming turns your skin color blueB.cold-water swimming causes more heart attacks in summer than in winterC.cold-water swimming can make the body temperature dangerously highD.Polar Bears are bears swimming in freezing water
