When prices are low people will buy more, and when prices are high they will buy less. Every shopkeeper knows this. But at the same time, producers want higher prices for their goods when they make more goods. How can we find the best price for the goods? The Law of Supply and Demand is the economist's answer to this question. According to this law, changes in the prices of goods cause changes in supply and demand. An increase in the price of the goods causes an increase in supply—the number of goods the producers make. Producers will make more goods when they can get higher prices for the goods. The producer makes more shoes as the price of shoes goes up. At the same time, an increase in the price of the goods causes a decrease in demand—the number of goods the consumers buy. This is because people buy less when the price is high. People buy fewer shoes as the price of shoes goes up. Conversely, a decrease in the price causes an increase in demand (people buy more shoes) and a decrease in supply (producers make fewer shoes). Business firms look at both supply and demand when they make decisions about prices and production. They look for the equilibrium point where supply equals demand. At this point, the number of shoes produced is 3000 and the price of the shoes is .3030 is the equilibrium price; at this price the consumers will buy all of the 3000 shoes which the producers make. If the producers increase the price of the shoes, or if they produce more than 3000 shoes, the consumers will not buy all of the shoes. The producers will have a surplus(过剩)—more supply than demand—so they must decrease the price in order to sell all of the shoes. On the other hand, if they make fewer than 3000 shoes, there will be a shoes shortage—more demand than supply—and the price will go up. According to the Law of Supply and Demand, the equilibrium price is the best price for the goods. The consumers and the producers will agree on this price because it is the only price that helps them both equally.1. Why does an increase in price cause an increase in supply?A.Consumers buy more goods when prices are high.B.Producers want to sell all of their goods.C.Producers make more goods when prices are high.D.Consumers will not buy all of the goods. 2. Why does a decrease in prices cause an increase in demand?E.Producers make fewer goods when prices are low.F.Consumers buy fewer goods when prices are low.G.Consumers buy more goods when prices are low.H.Producers make more goods when prices are high. 3. What do business firms look at when they make decisions about prices and production?I.The equilibrium point.J.The demand curve.K.The supply curve.L.All of the above. 4. Why will consumers and producers agree on the equilibrium price?M.It is the only price for the goods.N.It will help them both equally.O.All of the goods will be sold.P.It is the lowest price. 5. When will producers have a surplus of goods?Q.When supply-equals demand.R.When they sell all of their goods.S.When there is more demand than supply.T.When there is more supply than demand.

Teacher burnout （倦怠）and student stress may be linked, according to a University of British Columbia study. The study is the first of its kind to examine the connection between teacher burnout and students' cortisol levels（可体松水平）, which are a biological indicator of stress.Researchers collected saliva（唾液） samples from over 400 elementary school children and tested their cortisol levels. They found that in classrooms in which teachers experienced more burnout, or feelings of emotional exhaustion, students' cortisol levels were elevated. Higher cortisol levels in elementary school children have been linked to learning difficulties as well as mental health problems."This suggests that stress contagion might be taking place in the classroom among students and their teachers, " said Eva Oberle, the study's lead author and newly appointed assistant professor with the Human Early Learning Partnership （HELP） at UBC's school of population and public health. "It is unknown what came first—elevated cortisol or teacher burnout. We consider the connection between student and teacher stress a cyclical problem in the classroom."Oberle said a stressful classroom climate could be a result of inadequate support for teachers, which may impact teachers' ability to effectively manage their students. A poorly managed classroom can contribute to students' needs not being met and increasing stress. This could be reflected in elevated cortisol levels in students.Alternatively, stress could originate from students, who may be more challenging to teach because of increases in anxiety, behavioural problems, or special needs. In this scenario, teachers could feel overwhelmed and report higher levels of burnout."Our study is a reminder of the systemic issues facing teachers and educators as classroom sizes increase and supports for teachers are cut, " said Oberle."It is clear from a number of recent research studies that teaching is one of the most stressful professions, and that teachers need adequate resources and support in their jobs in order to battle burnout and alleviate stress in the classroom, " said UBC education professor Kimberly Schonert-Reichl, the study's co-author and director of HELP. "If we do not support teachers, we risk the collateral damage of students."Which is the best title for the passage? A.How to Relieve Stress in the classB.A Puzzling Question of Egg and ChildrenC.The most Stressful Profession in the worldD.The Link Between Students Stress and Teacher BurnoutParagraph 4 and paragraph 5 are intended to make it clear that .A.teacher burnout may be the cause of the elevated cortisol levels in studentB.the connection students and teacher stress is a cyclical problemC.students with higher stress level are more likely to have learning difficultiesD.students' behavioural problems may result in teacher's higher level of burnoutAccording to the writer, many British teacher face the problem that .A.teachers are not well trained to deal with students' problemB.teachers' income increases but teaching resources are cutC.there are more students in each class and less support for teachersD.there is a widening gap between students' need and teachers' abilityWhich of the following statement is NOT true? A.The more burnout teachers experience, the higher cortisol levels in students.B.Adequate support may help teachers manage students effectively.C.Students will benefit as a result of reduced teacher burnout.D.High cortisol levels indicates high level of burnout.

The case for college has been accepted without question for more than a generation. All high school graduates ought to go, says conventional wisdom and statistical evidence, because college will help them earn more money, become "better" people, and learn to be more responsible citizens than those who don't go. But college has never been able to work its magic for everyone. And now that close to half our high school graduates are attending, those who don't fit the pattern are becoming more numerous, and more obvious. College graduates are selling shoes and driving taxis; college students interfere with each other's experiments and write false letters of recommendation in the intense competition for admission to graduate school. Others find no stimulation(激发，刺激) in their studies, and drop out—often encouraged by college administrators. Some observers say the fault is with the young people themselves—they are spoiled and they are expecting too much. Others blame the state of the world, and they are partly right. We have been told that young people have to go to college because our economy can't absorb an army of untrained eighteen-year-olds. But disappointed graduates are learning that it can no longer absorb an army of trained twenty-two-year-olds, either. Some adventuresome educators and watchers have openly begun to suggest that college may not be the best, the proper, the only place for every young person after the completion of high school. We may have been looking at all those surveys and statistics upside down, it seems, and through the rosy glow(美丽光芒) of our own remembered college experiences. Perhaps college doesn't make people intelligent, ambitious, happy, liberal, or quick to learn things—maybe it is just the other way around, and intelligent, ambitious, happy, liberal, quick-learning people are merely the ones who have been attracted to college in the first place. And perhaps all those successful college graduates would have been successful whether they had gone to college or not. This is hard to believe for those of us who have been brought up to believe that if a little schooling is good, more has to be much better. But contrary evidence is beginning to mount up. 1.According to the author, ___. A.people used to question the value of college education. B.people used to have full confidence in higher education. C.all high school graduates went to college. D.very few high school graduates chose to go to college. 2.According to the passage, the problems of college education partly result from the fact that________. A.society cannot provide enough jobs for properly trained graduates. B.High school graduates do not fit the pattern of college education. C.Too many students have to earn their own living. D.College administrators encourage students to drop out. 3.In this passage the author argues that___. A.Intelligent people may learn quicker if they don't go to college. B.College education is not enough if one wants to be successful. C.ollege education benefits only the intelligent, ambitious, and quick-learning people. D.more and more evidence shows college education may not be the best thing for high school graduates

The Harry Potter series, written by J.K. Rowling, is perhaps the most popular set of novels of the modern era. With seven books and many successful films to its name, the series has gathered about 15 billion dollars in sales. How did the series become so popular? The reason can be broken down into several areas.The first book in the series was rejected 12 times before it was picked up by Bloomsbury—a small publisher in England. So receiving this contract was Rowling's first step to success. However, getting a book contract does not ensure the success of a book. The story was soon loved by children and adults alike. In light of this, Bloomsbury Publishing published a second version of the books with “adult” (less colorful and more boring) book covers. This made it easier for a full range of ages to enjoy the series.Another factor that worked like a charm was that the publisher and Rowling herself, through the books, conducted midnight releases, promotions, and pre-ordering more readers. Customers who feared that their local bookstore would run out of copies responded by pre-ordering over 700,000 copies before the July 8, 2000 release.What does the underlined word “releases” (Para. 3) mean?A. The activity that frees or expresses energy or emotion.B. The announcement about the book’s publishing information.C. The sales of books that is available only at midnight.

Most children with healthy appetites are ready to eat almost anything that is offered them and a child rarely dislikes food (51) it is badly cooked. The way a meal is cooked and served is most important and an (52) served meal will often improve a child’s appetite.

If the father says he hates fat meat or the mother refuses vegetables in the child’s hearing he is (54) to copy this procedure. Take it (55) granted that he likes everything and he probably will.

At meal times it is a good idea to give a child a small portion and let him (57) back for a second helping rather than give him as much as he is likely to eat all at once. Do not talk too much to the child (58) meal times, but let him get on with his food, and do not allow him to leave the table immediately after a meal or he will soon learn to swallow his food (59) he can hurry back to his toys.

The increase in international business and in foreign investment has created a need for executives with knowledge of foreign languages and skills in cross-cultural communication. Americans, however, have not been well trained in either area and, consequently, have not enjoyed the same level of success in negotiation in an international arena as have their foreign counterparts. Negotiating is the process of communicating back and forth for the purpose of reaching an agreement. It involves persuasion and compromise, but in order to participate in either one, the negotiators must understand the ways in which people are persuaded and how compromise is reached within the culture of the negotiation. In many international business negotiations abroad, Americans are perceived as wealthy and impersonal. It often appears to the foreign negotiator that the American represents a large multi-million-dollar corporation that can afford to pay the price without bargaining further. The American negotiator’s role becomes that of an impersonal supplier of information and cash. In studies of American negotiators abroad, several traits have been identified that may serve to confirm this stereotypical perception, while undermining the negotiator’s position. Two traits in particular that cause cross-cultural misunderstanding are directness and impatience on the part of the American negotiator. Furthermore, American negotiators often insist on realizing short-term goals. Foreign negotiators, on the other hand, may value the relationship established between negotiators and may be willing to invest time in it for long-term benefits. In order to solidify the relationship, they may opt for indirect interactions without regard for the time involved in getting to know the other negotiator. Clearly, perceptions and differences in values affect the outcomes of negotiations and the success of negotiators. For Americans to play a more effective role in international business negotiations, they must put forth more effort to improve cross-cultural understanding. [共5题](1)What kind of manager is needed in present international business and foreign investment? [本题2分]A. The man who represents a large multi-million-dollar corporation. B. The man with knowledge of foreign languages and skills in cross-cultural communication. C. The man who is wealthy and impersonal. D. The man who can negotiate with his foreign counterparts.

Americans experience more food recalls (召回) today than they did five years ago, especially when it comes to meat and poultry (家禽). Meat and poultry recalls increased by two-thirds from 2013 to 2018, while food recalls overall went up 10%, according to the report recently published by the U.S. Public Interest Research Group.Meanwhile, the U.S. Centers for Disease Control and Prevention estimates (估计) 48 million people get sick, 128,000 are hospitalized and 3,000 die from food-borne disease each year in the U.S. "We are looking for the farm-to-fork preventative solutions," said Adam Garber, the research group's consumer watchdog. "By doing that, we can protect people's health."Over the five-year period, poultry posted the most recalls (168), followed by beef (137) and pork (128). The report shows the most serious meat recalls are on the rise. Among meat and poultry, the number of Class I recalls has increased by 83%, nearly doubling. Class I, the most serious of the recalls, is issued when there is a reasonable probability that the food will cause health problems or death.53. When would Class I recalls be issued?A. When the food is likely to cause health problems or death.B. When there are too many complaints from customers.C. When the food problem lasts for five years.D. When the product quality is below standard.
