with the evening my wife and I spent at your restaurant two nights ago While the food was as usual very good I regret to inform you that the service from our waiter Max was most unsatisfactory First of all when we arrived we discovered our table overlooking the garden had been given away to some other customers The new table we finally received was by the door and when I complained Max just laughed Furthermore as we were sitting down he was extremely familiar with my wife which deeply made her uncomfortable When our meal came he served the food casually and at the end cleared the plates in a most rude fashion Regarding the payment of service I noticed your menu which says that the matter of rewarding service is at the willingness of the guest In addition I should point out that on other occasions I have left at least 12 percent This time I felt right in leaving nothing I regret having to write this letter but as a regular customer I am extremely displeased and did not expect to be treated in this manner I look forward to hearing from you with a satisfactory reply or if you prefer we could meet in person to resolve this matter Yours sincerely Rupert Metcalf 1 Mr Metcalf had dinner in the restaurant on A 16th JanuaryB 17th January C 18th JanuaryD 19th January 2 How many complaints does Mr Metcalf have in his letter A One B Two C Four D Six B Have you ever noticed when looking at a map of the world that the east coast of South America and the west coast of Africa look as though they might fit together If you have you are not alone In 1965 the English scientist Sir Edward Bullard used a computer to test the fit of the two continents and found that at an ocean depth of 2000 metres the match was very close indeed It seems too remarkable to be possible but there is a lot of evidence 证据 to suggest that Africa was once joined to South America For example there is a 用心 爱心 专心2 belt of ancient rocks along the east coast of Brazil which is similar to the rocks across the South Atlantic in West Africa There is further evidence that existing land masses were once linked The remains of a 400 to 500 million year old mountain chain has been found running down the eastern part of Greenland western Scandinavia and through north west Scotland and Ireland into western Canada eventually finding their way to north west Africa Then there is the evidence from life itself In various parts of the world today the same animals and plants can be found on land masses separated by in some cases thousands of miles of oceans Did they develop at the same time in two different places It seems unlikely Biologists believe that there must have been land bridges which have now sunk beneath the sea Also fossils 化石 found in sedimentary rocks fossils are the preserved remains of life forms have allowed geologists to trace the same plants from South America and Antarctica 北极 in rocks perhaps 300 million years old The ice that is now confined to 限制 the polar regions 北极或南极地区 has not always been so limited in extent Indeed during a period of the Earth s history known as the permocarboniferous age 二叠石炭纪 about 250 350 million years ago there is evidence from the rocks that there were glaciers covering South America parts of Africa India Australia as well as Antarctica On the other hand in the northern hemisphere 北半球 there were deserts If the continents sparead out as they are today it is hard to understand how this could be So there is considerable evidence to show whole continents moved apart and naturally many people have tried to discover how and why whole land masses moved 3 How many proofs does the author give in the passage A 3 B 6 C 4 D 7 C The outburst of joy at the success of China s national football team in reaching the World Cup finals easily matched the scenes of celebration which attended Beijing s Olympic bid win It s little surprise football fans had waited 44 years for that moment three times longer than the seemingly endless World Trade Organization negotiations 谈判 The 53 year old Serb coach 教练 Bora Milutinovic is regarded now as nothing less than a saviour by football fans used to years of broken dreams and bitter setbacks Best known to fans as Milu he has been believed by many with playing a major role in helping the Chinese team win its tickets to the 2002 World Cup being co hosted by South Korea and Japan Having already guided Mexico Costa Rica Nigeria and the United States to the World Cup finals Bora Milutinovic managed to continue his winning streak in China He made it clear however last Friday in Shenyang Wulihe Stadium that he preferred not to be seen as a miracle worker 用心 爱心 专心3 Before guiding the Chinese team to the finals Milu was one of only two coaches in the world to take four national sides to the final stages The other one is Carlos Alberto Parreir Milu however is the only man to take all for teams to the second round of the finals And now he was gone on better

traffic accidents in 2001 totaled 270 000 fewer by 20 000 than in 2000 But the number of the dead for 2001 was 54 000 an increase of 1 000 from the year before The increase was not as slow as that in recent years A government official said in Beijing yesterday that 3 821 persons were killed in highway traffic accidents last month a drop of 12 8 percent from January 2001 He also said there were 21 201 traffic accidents in the first month of the year 10 1 percent fewer than January last year and 11 700 people injured The traffic accidents last year caused a loss worth 27 32 million yuan about 2 9 million US dollars Economic Daily also said 170 000 persons were injured in the traffic accidents in 2001 fewer by 10 000 than in 2000 From China Daily February 16 2002 1 In 2000 the total number of the traffic accidents was A 20 000B 250 000C 290 000D 310 000 2 In 2000 persons were killed in the traffic accidents A 1 000B 53 000C 54 000D 55 000 3 Which is true according to the news report A The traffic accidents in 2002 will go up continuously B Economic Daily said the traffic accidents caused a loss worth 2 9 million US dollars in 2000 C In January 2002 there were 3 821 highway traffic accidents D There were more traffic accidents in January 2001 than in January 2002 B Microwaves that transmit television signals always travel in straight lines Because the earth is round it is impossible to send live television over a long distance For example if we tried to send television signals directly from Europe to America the microwaves carrying the signals would shoot into space over the Atlantic and would never reach America If we want to send television signals around the surface of the earth we must send them from point to point by the relay system On land we can set up relay 用心 爱心 专心6 stations 转播站 for this purpose and we can pass signals from station to station in a series of straight lines However we cannot do this so easily over water In order to send pictures directly across the Atlantic for example we would need to build a chain of relay stations across the ocean which is about 3 000 miles wide One choice would be to build one great tower in the middle of the ocean But the tower would have to be 500 miles high Both of these ideas are impossible So we use the communication satellite thousands of miles in outer space to relay the television signals across the Atlantic A satellite receives the picture signals in a straight line from the ground station on one side of the Atlantic from England for example Then it sends signals down again Also in a straight line to the ground station on the other side of the Atlantic in the United States The communication satellite must be within the view of both ground stations at the same time 4 According to the passage if we want to receive the TV programme all over the world freely how many satellites shall we have at least A Two B Three C Four D Five C A breakthrough in the provision of energy from the sun for the European Union EU could be brought forward by up to two decades if a modest increase could be provided in the EU s research effort in this field according to the senior EU scientists engaged in experiments in solar energy at EU s scientific laboratories at Ispra near Milan The senior West German scientist in charge of the EU s solar energy programme Mr Joachim Gretz told reporters that at present levels of research spending it was most unlikely that solar energy would provide as much as three per cent of the EU s energy requirements even after the year 2010 But they said that with a modest increase in the present sums devoted by the EU to this work it was possible that the breakthrough could be achieved by the end of the next decade Mr Gretz figures out that if solar energy only provided three percent of the EU s needs this could still produce a saving of about a billion dollars in the present bill for imported energy each year And he believes that with the possibility of using more advanced technology in this field it might be possible to satisfy a much bigger share of the EU s future energy needs At present the EU spends about 2 6 million a year on solar research at Ispra one of the EU s official joint research centres and another 3 million a year in indirect research with universities and other independent bodies 5 According to Mr Gretz the present sum of money will enable the scientists to provide A more than 3 of th EU needs after the year 2010 B only 3 of the EU needs before the year 2010 C less than 3 of the EU needs before the year 2010 D only 3 of the EU needs even after the year 2010 用心 爱心 专心7 D Do you love holidays but hate the increase in weight that follows You are not alone Holidays are times for splendid meals and celebrating especially with the cultural foods of our heritage With proper planning though it is possible to maintain 保持 normal weight during the holidays The idea is to enjoy the holidays and think in terms of moderation 节制 Whether it is celebrating at the office party or sitting down for the traditional family dinner approach 看待 eating as a time for tasting or sampling a variety of foods Here are some tips to carry you through the round of celebrations and your social calendar without feeling having done wrong Set realistic goals Unless you have special dietary needs there are no forbidden foods Don t turn down the foods you enjoy but be sensible Don t skip meals Before you leave home have a small low fat meal or snack This can help you to avoid excessive eating or drinking Control portions 食量 Use a small luncheon size plate and avoid the large platters that may encourage you to load up You should be most comfortable eating an amount of food about the size of your fist Once you have had your tasting serving move away from the buffet Doing so will make it less tempting to be eating constantly as your appetite is stimulated by the sight of food Eat slowly and savor Approach eating as a time for lasting or sampling a range of foods Savor the flavors Eat at a leisurely pace Fill up before hand with clear soup and raw fruit or vegetables and fruit in a yogurt dressing rather than cream and cheese sauces Drink a large glass of water before you eat to help you feel full If you have a sweet tooth try mints hard candies and fruits These don t have the fat content of creamy desserts and chocolate Maintain physical activity Don t let exercise take a break during the holidays A 20 minute brisk walk after a meal can help burn off excess calories Avoid high fat foods Dishes that look oily or creamy may have a generous amount of fat Choose lean meats Fill your plate with salad and green vegetables 6 How many pieces of advice does the writer offer in the passage A
