Before fixing any equipment, be familiar with your company's safety rules for working with electrical equipment. These rules determine the methods you can use.Next, gather information about the equipment and the problem. Make sure you know how it should work normally. Having this understanding makes it easier to analyze any faults. Operation manuals and drawings are valuable sources of information. If there are equipment history records, you should review them to see if there are any frequent problems.In many cases, faults exhibit obvious signs that indicate their cause. Through careful examination and logical reasoning, it is often possible to discover the actual faulty part with very little testing.In addition, it is important to use your other senses when examining equipment. The smell of burnt insulation (绝缘材料), for example, can be a strong indicator (信号) of a problem. Paying attention to the sounds produced by the equipment during operation may also provide valuable clues. Furthermore, checking the temperature of various parts can help discover an issue, but be careful while doing this as some parts may carry electrical current or be hot enough to cause burns.40.

E Argentina in the late nineteenth century was an exciting place. Around 1870, it was experiencing an economic(经济的) boom, and the capital, Buenos Aires, attracted many people. Farmers, as well as a flood of foreigners from Spain and Italy, came to Buenos Aires seeking jobs. These jobs didn′t pay well, and the people felt lonely and disappointed with their new life in the city. As the unhappy newcomers mixed together in the poor parts of the city, the dance known as the tango(探戈舞) came into being. At the beginning the tango was a dance of the lower classes. It was danced in the bars and streets. At that time there many fewer women than men, so if a man didn't want to be left out, his only choice was to dance with another man so that he could attract the attention of the few available women. Gradually, the dance spread into the upper classes of Argentinean society and became more respectable. In Europe at this time, strong interest in dance from around the world was beginning. The interest in international dance was especially evident in Paris. Every kind of dance from ballet(芭蕾舞) to belly dancing could be found on the stages of the Paris theaters. After tango dances from Argentina arrive in Europe, they began to draw the interest of the public as they performed their exiting dance in cafes. Though not everyone approved of the new dance, saying it was a little too shocking, the dance did find enough supporters to make it popular. The popularity(流行) of the tango continued to grow in many other parts of the world. Soldiers who returned to the United States from World War I brought the tango to North America. It reached Japan in 1926, and in 2003 the Argentinean embassy in Seoul hired a local tango dancer to act as a kind of dance ambassador, and promote tango dancing throughout South Korea. 1. The origin of the tango is associated with _____. A: belly dances B: Americans soldiers C: a Spanish city D: the capital of Argentina 2. Which of the following is true about the tango? A: It was created by foreigners from Spain and Italy. B: People of the upper classes loved the tango most. C: It was often danced by two male in the beginning. D: A dancer in Seoul became the Argentinean ambassador. 3. Before World War I, the tango spread to _____. A: America B: Japan C: France D: South Korea 4. What can be the best title for the text? A: How to Dance the Tango B: The History of the Tango C: How to Promote the Tango D: The Modern Tango Boom
Global warming is causing more than 300,000 deaths and about 125 billion in economic losses each year,according to a report by the Global Humanitarian Forum,an organization led by Annan,the former United Nations secretary general. The report,to be released Friday,analyzed data and existing studies of health,disaster,population and economic trends.It found that human-influenced climate change was raising the global death rates from illnesses including malnutrition (营养不良) and heat-related health problems. But even before its release,the report drew criticism from some experts on climate and risk,who questioned its methods and conclusions.Along with the deaths,the report said that the lives of 325 million people,primarily in poor countries,were being seriously affected by climate change.It projected that the number would double by 2030. Roger Pielke Jr.,a political scientist at the University of Colorado,Boulder,who studies disaster trends,said the Forum's report was"a methodological embarrassment"because there was no way to distinguish deaths or economic losses related to human-driven global warming amid the much larger losses resulting from the growth in populations and economic development in vulnerable (易受伤害的) regions.Dr.Pielke said that"climate change is an important problem requiring our utmost (极度的) attention."But the report,he said,"will harm the cause for action on both climate change and disasters because it is so deeply flawed (有瑕疵的)." However,Soren Andreasen,a social scientist at Dalberg Global Development Partners who supervised the writing of the report,defended it,saying that it was clear that the numbers were rough estimates.He said the report was aimed at world leaders,who will meet in Copenhagen in December to negotiate a new international climate treaty. In a press release describing the report,Mr.Annan stressed the need for the negotiations to focus on increasing the flow of money from rich to poor regions to help reduce their vulnerability(弱点) to climate hazards(危害)while still curbing (限制) the emissions of the heat-trapping gases.More than 90% of the human and economic losses from climate change are occurring in poor countries,according to the report.33.What is the finding of the Global Humanitarian Forum? ____ A.Global temperatures affect the rate of economic development.B.Rates of death from illnesses have risen due to global warming.C.Malnutrition has caused serious health problems in poor countries.D.Economic trends have to do with population and natural disasters.34.What is Soren Andreasen's view of the report? ____ A.Its rough estimates are meant to draw the attention of world leaders.B.It is vulnerable to criticism if the statistics are closely examined.C.It will give rise to heated discussions at the Copenhagen conference.D.Its conclusions are based on carefully collected data.35.What does Kofi Annan say should be the focus of the Copenhagen conference? ____ A.How rich and poor regions can share responsibility in curbing global warming.B.How human and economic losses from climate change can be reduced.C.How emissions of heat-trapping gases can be reduced on a global scale.D.How rich countries can better help poor regions reduce climate hazards.

A number of recent books have reworked subjects, forms and writing techniques. Today's children read stories about divorce, death, drugs, air pollution, political extremism and violence. Relying on the magic of the illustrator, all kinds of books are being published. Before they know to read, babies can play with books made of cloth or books made to take in the bath. Later on, they are given picture books that may be cubical (立方形的) or triangular, outsized or very small. They also like work-books which come with watercolors and paintbrushes, and comic books (漫画册) filled with details where they have to spot a figure hidden among thousands of others. Not that the traditional children's books are being neglected. There are still storybooks where the pages pop up (跳起) when they are opened, to make a forest or a castle. Among the latest ideas are interactive stories where readers choose the plot (情节) or ending they want, and books on CD, which are very popular, in rich industrialized countries. The public has enthusiastically greeted the wealth of creativity displayed by publishers. "Previously, giving a child a book as often seen as improper," says Canadian author Marie-France Hebert. Her books, published by a French-language publisher, sell like hot cakes in hundreds of thousands of copies. "There's a real appetite for reading these days and I try to get across to children the passion for reading which is food for the mind and the heart, like a medicine or a vitamin. "Reworked" as used in Paragraph 1 means "______" A.reworded B.rewritten C.processed D.revised
What is Soren Andreasen"s view of the report?A. Its conclusions are based on carefully collected data.B. It is vulnerable to criticism if the statistics are closely examined.C. It will give rise to heated discussions at the Copenhagen conference.D. Its rough estimates are meant to draw the attention of world leaders.

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.

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.

question or statement.Hot pot is a traditional dish in China. It is believed to date back more than 1,000 years to the time of the Jin Dynasty. Hot pot's origins can be found in the dining practices of Mongolian horsemen who rode across the steppe and into northern China. Legend has it that the Mongols used their helmets as pots to simmer (炖) broth (汤底) over open fires, and cooked chunks of meat in the broth.Hot pot cooking seems to have spread to northern China during the Tang Dynasty. In the regional variations developed with different ingredients such as seafood. In the centuries that witnessed the growth of the Song Dynasty, hot pot moved — and changed — further south, with each successive region adapting it to their local ingredients and tastes.The ingredients in a hot pot vary a lot from region to region. Perhaps the most famous hot pot is the Chongqing or Sichuan hot pot. It features a dark red broth chock-full (塞满了的) of spices, chili peppers, and the uniquely mouth-numbing Sichuan peppers. In Beijing and elsewhere in the north, hot pot broth tends to be mild and, compared to its racy southern "cousins", a little light. In the northeast of China, a kind of local sauerkraut (酸菜) is used to add some tang (强烈的味道), making the broth a bit sour. People can choose a version of hot pot according to their taste.1 Hot pot is believed to date back more than 1,000 years to the time of _______.A. the Jin Dynasty B. the Tang DynastyC. the Song Dynasty D. the Yuan Dynasty
