单选题{{B}}Text 3{{/B}} To find Kim Hyung Gyoon's office in Samsung's R the others were washed in a machine with the Ag + Nano System.The next day, I asked everyone to check the odor of their socks after a day's wear.One began to produce a strong unpleasant smell, and the other was odorless." Kim says he came up with the idea five years ago while on a business trip to Japan, where he learned of a brand of socks that retained their freshness even after many days of unwashed wear and tear.Tiny sticks of silver with germ-killing chemicals were woven into fabric.When he got back to Seoul, Kim applied the principle to washing machines. According to the Korea Testing the revolutionary technology is also being used in Samsung's refrigerators and air conditioners. No wonder: consumers seem to like a little silver in their spin cycles.Since Samsung's nano-armed products were first launched, they have brought in an estimated $779 million in revenue.Overall, nanotech has been one of science's fastest- growing fields in recent years, with potential applications in fields as diverse as energy production and toothpaste manufacture.The nanotech market is projected tO be worth $1 trillion by 2015.

单选题Read the pieces taken from five letters to a magazine by five people commenting on an article about global warming. For questions 61 to 65, match the name of each person ( 61 to 65) to one of the statements (A to G)given below. Mark your answers on ANSWER SHEET 1. Mikhil Jaisinghani: After reading your article "The Truth About Global Warming" , I''m no less concerned about the earth''s environmental condition. You say "Scientists are still differing with huge gaps in their knowledge." But Lindzen, the writer of the article, is no closer to the truth simply because he can criticize. Global warming may be far from understood, but let us act to prevent it anyway, just in case the effects are real. John Leaver: It''s shameful that you present Lindzen''s views on climate change as "The Truth About Global Warming." It seems that your magazine is keeping an open mind, even though you admit that most climate scientists disagree with Lindzen''s opinions. You characterize the view that waste gases should be cut as "very European." I take it that it is very American to pursue a policy of unlimited energy consumption without considering what most scientists and other countries think. Thomas Hervouet: How can we believe a man who holds that there is only a very weak link between lung cancer and cigarette smoking? Lindzen''s position is unacceptable because it shows his lack of knowledge about cancer. I believe that French President Jacques Chirac is more informed on global warming — which no serious scientist denies — than President Bush, whose interests depend on the oil industry. Hans-Joachim Hell: What Lindzen says makes sense to me. For years I''ve read articles on negative climatic change and greenhouse effect. The only agreement seems to be "We agree that we disagree. " Considering the recent chilly summers in Germany, I''ve no idea where the "warming" can be found. In past decades, summers were hot, almost unbearable. Now, in the midst of summer, we turn the heaters on and wear warm clothes. Derek Kickinson: The U. S. government should act for the American people by signing the Kyoto Agreement, instead of acting for Big Oil in America. Even if scientists cannot agree on the numbers, global warming is taking place, and this is not beneficial for the planet. The anti-Kyoto position of the U. S. government is a short-term political move, but the long-term losers will be the American people and the environment. Now match the name of each person (61 to 65) to the appropriate statement. Note: there are two extra statements. Statements [A] Lindzen really has a point to make on global warming. [B] America will pay a price for its shortsightedness some day. [C] Though opinions on global warming vary, we have to do something about it. [D] Lindzen seems unqualified to speak of the effects of global warming on health. [E] You really have an open mind to present Lindzen''s position on global warming. [F] It''s good that Lindzen''s article helps further the discussion on global warming. [G] America''s attitude toward waste gas control is to be blamed rather than Europe''s.

单选题Directions: Read the following text. Choose the best word or phrase for each numbered blank and mark A, B, C or D on ANSWER SHEET 1. Generations of Americans have been brought {{U}} {{U}} 1 {{/U}} {{/U}}to believe that a good breakfast is important for health. Eating breakfast at the {{U}} {{U}} 2 {{/U}} {{/U}}of the day, we have all been {{U}} {{U}} 3 {{/U}} {{/U}}, is as necessary as putting gasoline in the family car {{U}} {{U}} 4 {{/U}} {{/U}}starting a trip.

Between 1978 and 1983, the latest years for which figures are {{U}} {{U}} 8 {{/U}} {{/U}}, the number of people who didn't have breakfast increased {{U}} {{U}} 9 {{/U}} {{/U}}33 percent—from 8.8 million to 11.7 million {{U}} {{U}} 10 {{/U}} {{/U}}the Chinese-based Market Research Corporation of America. For those who feel pain of {{U}} {{U}} 11 {{/U}} {{/U}}about not having breakfast, {{U}} {{U}} 12 {{/U}} {{/U}}, there is some good news. Several studies in the last few years {{U}} {{U}} 13 {{/U}} {{/U}}that, for adults especially, there may be nothing {{U}} {{U}} 14 {{/U}} {{/U}}with omitting breakfast. "Going {{U}} {{U}} 15 {{/U}} {{/U}}breakfast does not affect {{U}} {{U}} 16 {{/U}} {{/U}}." Said Arnold E. Bendoer, former professor of nutrition at Queen Elizabeth College in London, {{U}} {{U}} 17 {{/U}} {{/U}}does giving people breakfast improve performance. {{U}} {{U}} 18 {{/U}} {{/U}}evidence relating breakfast to better health or {{U}} {{U}} 19 {{/U}} {{/U}}performances is surprisingly inadequate, and most of the recent work involves children, not {{U}} {{U}} 20 {{/U}} {{/U}}. "The literature," says one researcher, Dr. Ernesto Pollitt at the University of Texas, "is poor."
