Ques: In the earliest stages of man's development he had no more need of money than animals have. He was content with very simple forms of shelter, made his own rough tools and weapons and could provide food and clothing for himself and his family from natural materials around him. As he became more civilized, however, he began to want better shelter, more efficient tools and weapons, and more comfortable and more lasting clothing than could be provided by his own neighborhood or by the work of his own unskilled hands. For these things he had to turn to the skilled people such as smiths, leather workers or carpenters. It was then that the question of payment arose. At first he got what he wanted by a simple process of exchange. The smith who had not the time to look after land or cattle was glad to take meat or grain from the farmer in exchange for an axe or a plough . But as more and more goods which had no fixed exchange value came on the market, exchange became too complicated to be satisfactory. Another problem arose when those who made things wanted to get stocks of wood or leather, or iron, but had nothing to offer in exchange until their finished goods were ready. Thus the difficulties of exchange led by degree to the invention of money. In some countries easily handled things like seeds or shells were given a certain value and farmer, instead of paying the smith for a new axe by giving him some meat or grain, gave him so many shells. If the smith had any shells left when he had bought his food, he could get stocks of the raw materials of his trade. In some countries quite large things such as cows or camels or even big flat stones were used for trade. Later, pieces of metal, bearing values according to the rarity of the metal and the size of the pieces, or coins were used. Money as we know it had arrived. As men became more civilized they _ . A) all learnt to make by themselves the things needed B) had to travel a lot to look for what they wanted C) wanted better things than those they themselves could provide D) no longer provided food and clothing for themselves
Ans: C

Ques: In the age of reality television.success isn't the only way to the public eye.Failure can also create fame,just like William Hung,21,a native of Hong Kong. Hung recently has made an agreement with US-based entertainment firms Koch Records and Fuse Music Network.They wilt publish a full-length record,titled"The True Idol"on April 6. The idol is a civil engineering student at the University of California at Berkeley He did a version of Ricky Martin's"She Bangs"on the television show"American Idol 3",on January27.The Fox TV singing contest searches for pop stars among ordinary people.In the case of Hung,however, his act was so bad that the judges cut him off in mid-act.Hung's response,"I already gave my best,so I have no regrets at all."That's good,because any common person would have found plenty to regret:The off-key singing.The blue Hawaiian shirt worn with pants pulled up too high The terrible dancing The hips jerking to a beat that did not belong to the song,maybe not even to this planet.It was,by all accounts,bad. But,it was this very bad act that sold well. Marc Juris,president of Fuse,explained it this way,"Every one of us is happily guilty of singing our favorite song at the top of our lungs with complete freedom.completely oft-key and completely unworried That's what William did and immediately won the hearts of America." Whatever it is,for the moment it is big.Three websites devoted to Hung have gone up on the Internet in the past few weeks.Versions of his performance have been remixed with hip hop and techno-music and have made it to the top 10 request list at a Chicago radio station. So,what does Hung think of this? "There were all these people saying things about me A lot were saying I was very courageous and that I was great on the show, but some didn't have much respect for me and some were kind of mean." Now he says he's not so sure whether to distance himself from the glamour or to accept it Returning to normal hasn't been easy. What is the main idea of this passage? A) Sometimes an idol behaves quite foolishly. B) Hung's performance attracted the public eye. C) How an unsuccessful person became famous. D) Success sometimes does not require hard work.

Ques: Without proper planning, tourism can cause problems. For example, too many tourists can crowd public places that are also enjoyed by the inhabitants of a country. If tourists create too much traffic, the inhabitants become annoyed and unhappy. They begin to dislike tourists and to treat them impolitely. They forget how much tourism can help the country's economy. It is important to think about the people of a destination country and how tourism affects them. Tourism should help a country, keep the customs and beauty that attract tourists. Tourism should also advance the wealth and happiness of local inhabitants. Too much tourism can be a problem. If tourism grows too quickly, people must leave other jobs to work in the tourism industry. This means that other parts of the country's economy can suffer. On the other hand, if there is not enough tourism, people can lose jobs. Businesses can also lose money. It costs a great deal of money to build large hotels, airports, air terminals, first- class roads, and other support facilities needed by tourist attractions. For example, a major international class tourism hotel can cost as much as 50 thousand dollars per room to build. If this room is not used most of the time, the owners of the hotel lose money. Building a hotel is just a beginning. There must be many support facilities as well, including roads to get to the hotel, electricity, sewers to handle waste, and water. All of these support facilities cost money. If they are not used because there are not enough tourists , jobs and money are lost. It can be inferred from the text that _ . A) the author doesn't like tourism developing so fast B) local people will benefit from tourist attraction C) other parts of a country's economy won't benefit from tourism much D) we can't build too many support facilities
Ans: B

Ques: A rainfores is an area covered by tall trees with the total high rainfall spreading quite equally through the year and the temperature rarely dipping below 16degC.Rainforests have a great effect on the world environment because they can take in heat from the sun and adjust the climate. Without the forest cover, these areas would reflect more heat into the atmosphere,warming the rest of the world .Losing the rainforests may also influence wind and rainfall patterns, potentially causing certain natural disasters all over the world. In the past hundred years, humans have begun destroying rainforests in search of three major resources : land for crops, wood for paper and other products, land for raising farm animals. This action affects the environment as a whole. For example,a lot of carbon dioxide in the air comes from burning the rainforests. People obviously have a need for the resources we gain from cutting trees but we will suffer much more than we will benefit . There are two main reasons for _ . Firstly, when people cut down trees, generally they can only use the land for a year or two. Secondly, cutting large sections of rainforests may provide a good supply of wood right now, but in the long run it actually reduces the world' s wood supply. Rainforests are often called the world's drug store. More than 25% of the medicines we use today come from plants in rainforests. However, fewer than 1% of rainforest plants have been examined for their medical value. It is extremely likely that our best chance to cure diseases lies somewhere in the world's shrinking rainforests. ..Rainforests can help to adjust the climate because they _ . A) reflect more heat into the atmosphere B) bring about high rainfall throughout the world C) rarely cause the temperature to drop lower than 16degC D) reduce the effect of heat from the sun on the earth
