Ques:Read the following article and select the best answer. Article: Everybody hates it, but everybody does it. A recent report said that 40%of Americans hate tipping. In America alone, tipping is a $16 billion-a-year industry. Consumers acting politely ought not to pay more than they have to for a given service. Tips should not exist. So why do they? The common opinion in the past was that tips both rewarded the efforts of good service and reduced uncomfortable feelings of inequality. And also, tipping makes for closer relations. It went without saying that the better the service, the bigger the tip. But according to a new research from Cornell University, tips no longer serve any useful function. The paper analyzes numbers they got from 2,547 groups dining at 20 different restaurants. The connection between larger tips and better service was very weak. Only a tiny part of the size of the tip had anything to do with the quality of service. Tipping is better explained, by culture than by the money people spend. In America, the custom came into being a long time ago. It is regarded as part of the accepted cost of a service. In New York restaurants, failing to tip at least l5% could well mean dissatisfaction from the customers. Hairdressers can expect to get l5%-20%, and the man who delivers your fast food $2. In Europe, tipping is less common. In many restaurants the amount of tip is decided by a standard service charge. In many Asian countries, tipping has never really caught on at all. Only a few have really taken to tipping. According to Michael Lynn, the Cornell papers' author, countries in which people are more social or outgoing tend to tip more. Tipping may reduce anxiety about being served by strangers. And Mr. Lynn says, "In America, where people are expressive and eager to mix up with others, tipping is about social approval. If you tip badly, people think less of you. Tipping well is a chance to show off." Question: This passage is mainly about _ . - different kinds of tipping in different countries - the relationship between tipping and custom - the origin and present meaning of tipping - most American people hate tipping

Ans:the origin and present meaning of tipping

Ques:Read the following article and select the best answer. Article: People do not analyze every problem they meet. Sometimes they try to remember a solution from the last time they had a similar problem. They often accept the opinions or ideas of other people. Other times they begin to act without thinking. They try to find a solution by trial and error. However, when all these methods fail, the person with a problem has to start analyzing. There are six stages in analyzing a problem. First the person must recognize that there is a problem. For example, Sam's bicycle is broken, and he cannot read it to class as he usually does. Sam must see that there is a problem with his bicycle. Next the thinker must define the problem. Before Sam can repair his bicycle, he must find out the reason why it does not work. For instance, he must determine if the problem is with the gears, the brakes, or the frame. He must make his problem more specific. Now the person must look for information that will make the problem clearer and lead to possible solutions. For instance, suppose Sam decided that his bike does not work because there is something wrong with the gear wheels. At this time, he can look in his bicycle repair book and read about gears. He can talk to his friends at the bike shop. He can look at his gears carefully. After studying the problem, the person should have several suggestions for a possible solution. Take Sam as an illustration. His suggestions might be: put oil on the gear wheels; buy new gear wheels and replace the old ones; tighten or loosen the gear wheels. Eventually one suggestion seems to be the solution to the problem. Sometimes the final idea comes very suddenly because the thinker suddenly sees something new or sees something in a new way. Sam, for example, suddenly sees that there is a piece of chewing gum between the gear wheels. He immediately realizes the solution to his problem: he must clean the gear wheels. Finally the solution is tested. Sam cleans the gear wheels and finds that afterwards his bicycle works perfectly. he has solved the problem. Question: Which of the following is _ ? - People do not analyze the problem they meet. - People often accept the opinions or ideas of other people. - People may learn from their past experience. - People can not solve some problems they meet.

Ans:People do not analyze the problem they meet.

Ques:Read the following article and select the best answer. Article: It is not easy to reach Panjiayu, a village in the countryside around Thangshan, Hebei province. To get to the isolated village, visitors first have to take a bus ride of about an hour to the Fengrun district before taking a long-distance bus, which usually runs five times a day. Surrounded by mountains and bathed in plentiful sunlight, Panjiayu is nicknamed "Turpan", after the city in the Xinjiang Uygur Autonomous Region that is famous for its sweet grapes. The fruit is the Panjiayuy's main money spinner ------ the courtyard of almost every home boasts at least one grape trellis , and the main road is enlaced by vines. Last year, about 200,000 tourists from nearby cities visited Panjiayu. Even so, the place has retained its traditional feel. When night falls, except for a few road lamps that send out a dim light, the village is shrouded in darkness, the silence only broken by the occasional bark of a dog. So why does this village of just 1,500 residents attract so many visitors? Grapes are only part of the reason; most of the tourists visit to commemorate a massacre that happened 73 years ago. The modern building that seems so _ with the traditional feel of the place is a memorial to the events of Jan 25, 1941, two days before Lunar New Year, when the Japanese army carried out a frenzied slaughter of unarmed villagers. "About 1,298 of the 1,700 villagers were murdered. Of the survivors, 273 were not in the village that day, and although nearly 200 others survived, 98 of them were badly injured," said Pan Ruishen, the leader of the Panjiayu compensation Team for Japanese Atrocities . Panjiayu was just one of many massacres committed by the Japanese during the occupation of China before and during World War II, however, it is now a patriotism-education base because the village is full of sites of historical interest, such as the big lotus tree, whose hollow trunk was used to hide secret files of the Eighth Route Army, and the metal doors at the village entrance, which are scarred with countless white... Question: What can we know about Panjiayu from the text? - It is an isolated village with a long history in Hunan province. - Many tourists visited Panjiayu last year despite the fact that the place hasn't kept its traditional feel. - Panjiayu is viewed as a patriotism-education base in view of its historical events and many sites of historical interest . - All the residents were slaughtered by the Japanese during the occupation of China before World War II.
