1、The Value of AdvertisementMoney spent on advertising is worth spending. It serves directly to bring about a rapid sale of goods at reasonable prices, so setting up a firm home market and making it possible to provide for export at good price. By drawing attention to new ideas it helps greatly to raise standards of living. By helping to increase demand it causes an increased need for labor, and is therefore a nice way to fight unemployment. It lowers the costs of many services: without advertisements your daily newspaper would cost four times as much, the price of your television program would need to be doubled, and travel by bus or subway would cost more. And perhaps most important of all, advertising provides a promise of reasonable value in the products and services you buy. Besides the fact that twenty-seven Acts of Parliament govern the terms of advertising, no regular advertiser dare produce anything that fails to live up to the promise of his advertisements. He might fool some people for a little while through misleading advertising. He will not do so for long, for the public has the good sense not to buy the poor goods more than once. If you see a product frequently advertised, it is the proof I know that the product does what is promised for it, and that it has good value. Advertising does more for the good of the public than any other force I can think of. There is one more point I feel I ought to touch on. Recently I heard a well-known television person declare that he was against advertising because it persuades rather than informs. He was telling us the real difference. Of course advertising tries to persuade. If its messages were nothing but information, that would be difficult to get more people to buy, for even the choice of the color of a shirt is a bit persuasive-advertising would be so boring that no one would pay any attention. But perhaps that is what the well-known television person wants.Which of the following is the most important advantage according to the passage?【单选题】

A.Reducing the cost of your daily newspaper.

B.Lowering the price of your television program.

C.Making it possible to provide for export at good price.

D.Providing a promise of reasonable value in the products and services you buy.

正确答案:D

答案解析:选项A、B、C、D都是提到的好处，但是从文章第2段第1句可知，最重要的是广告能提供产品和服务的价值承诺。因此选D。

2、What Is the Coolest Gas in the Universe?What is the coldest air temperature ever recorded on the Earth? Where was this low temperature recorded? The coldest recorded temperature on Earth was - 91℃, which occurred in Antarctica (南极洲) in 1983.We encounter an interesting situation when we discuss temperatures in space.Temperatures in Earth orbit actually range from about +120℃ to - 120℃. The temperature depends upon whether you are in direct sunlight or shade. Obviously, -120℃ is colder than our body can safely endure. Thank NASA science for well, de signed space suits that protect astronauts from these temperature extremes.The space temperatures just discussed affect only our areal of the solar _____. Obviously, it is hotter closer to the Sun and colder as we travel away from the Sun. Astronomers estimate temperatures at Pluto are about - 210℃. How cold is the lowest estimated temperature in the entire universe? Again, it depends upon your location. We are taught it is supposedly impossible to have a temperature below absolute zero, which is - 273℃, at which atoms do not move. Two scientists, whose names are Cornell and Wieman, have successfully cooled down a gas to a temperature barely above absolute zero. They won a Nobel Prize in Physics in 2001 for their work, not a discovery, in this case.Why is the two scientists\' work so important to science?In the 1920s, Satyendra Nath Bose was studying an interesting theory about special light particles we now call photons (光子). Bose had trouble convincing other scientists to believe his theory, so he contacted Albert Einstein. Einstein\'s calculations helped him theorize that atoms would behave as Bose thought—but only at very cold temperatures.Scientists have also discovered that ultra - cold(超冷) atoms can help them make the world\'s atomic clocks even more accurate. These clocks are so accurate today they would only lose one second every six million years! Such accuracy will help us travel in space because distance is velocity times time 4 ( d = v×t). With the long distances involved in space travel, we need to know time as accurately as possible to get accurate distance.【单选题】

A.system

B.energy

C.year

D.rays

正确答案:A

答案解析:本题难度不大，考查词义辨析，但干扰项干扰不大。可以先看选项得到信息提示。根据上下文逻辑，文章此处是说“太阳系”，答案是A。

3、Cell Phones1. Believe it or not, cell phones have been around for over a quarter of a century. The first commercial cell phone system was developed by the Japanese in 1979, but cell phones have changed a lot since that time. The early cell phones were big and heavy but they have developed into small and light palm sized models. There are huge developments in their functions, too. We have had call forwarding, text messaging, answering services and hands - free use for years, but now there are new facilities, such as instant access to the Internet and receiving and sending photos.2.

Cell phones have brought with them a number of new headaches for their owners. It costs a lot to replace stolen phones, It is becoming a frequent occurrence, and have you ever seen such a huge phone bills? More serious, however, Cell phones bring the potential health problem.

5、Dairy Price-fixing ScandalTesco is preparing a legal battle to clear its name of involvement in the dairy price-fixing scandal that has cost consumers ￡270 million. Failure to prove that it had no part in collusion with other supermarkets and dairy processors may land it with a fine of at least ￡80 million. The Office of Fair Trading (OFT) said yesterday that Asda, Sainsbury\'s and the former Safeway, plus the dairy companies Wiseman, Dairy Crest and Cheese Company, had admitted being in a cartel to fix prices for milk, butter and cheese. They were fined a total of just over ￡116 million as part of a leniency deal offered by the watchdog to companies that owned up quickly to anti-competitive behaviour.Officials at the OFT admitted privately that they did not think they would ever discover which company or individual had initiated the pricing formula. But the watchdog recognises that at the time supermarkets were under pressure from politicians and farmers to raise the cost of milk to save dairy farming, though it is not certain that money found its way to farmers. The OFT claimed in September that it had found evidence that the retail chains had passed future milk prices to dairy companies, which then reached a fixed price among themselves.The average cost to each household is thought to be ￡11.25 over 2002 and 2003, Prices went up an extra 3p on a pint of milk, 15p on a quarter of a pound of butter and 15p on a half pound of cheese. There is no direct recompense for consumers, however, and the money will go to the Treasury. The National Consumer Council gave warning that the admissions would dent consumer confidence in leading high street names and that people would become sceptical of their claims. Farmers for Action, the group of farmers that has led protests over low milk prices since 2000, is seeking legal advice on whether it can now bring a claim for compensation.The OFT investigation is continuing, however, in relation to Tesco, Morrisons and the dairy group Lactalis McLelland, and any legal action is expected to be delayed until that is completed. Tesco was defiant and said that it was preparing a robust defence of its actions. Lucy Neville-Rolfe, its executive director, said: "As we have always said, we acted independently and we did not collude with anyone. Our position is different from our competitors and we are defending our own case vigorously. Our philosophy is to give a good deal to customers."Morrisons has supported the OFT in inquiries into the former safeway business that it took over, but in a statement said that it was still making "strong representations" in its defence. A spokeswoman for Lactalis McLelland said that the company was "co-operating" with the OFT. Industry insiders suggested that the three companies were deliberately stalling the OFT investigation.Sainsbury\'s admitted yesterday that it had agreed to pay ￡26 million in fines, but denied that it had sought to profiteer. Justin King, the chief executive, said he was disappointed that the company had been penalised for actions meant to help farmers but recognised the benefit of a speedy settlement. Asda declined to say how much it would pay in fines and also said that its intention had been to help farmers under severe financial pressure.From the first paragraph, we may infer that ______.【单选题】

A.Tesco has cost consumers ￡270 million

B.Tesco has colluded with Asda, Wiseman, Dairy Crest and Cheese Company in fixing the dairy price

C.Tesco will be offered a leniency deal of 80 million

D.Tesco is trying its best to prove its innocence of the scandal

正确答案:D

答案解析:推理题。第一段主要讲述了Tesco公司已被卷入和其他公司联手划定牛奶价格的丑闻中，目前正在通过法律手段证明自己与此无关。因此选项D，Tesco正在竭力证明自己和丑闻无关，符合题意，故正确答案为D。
