11、 word for each numbered blank and mark A, B, C or D on ANSWER SHEET 1. 20 A Canadian researcher has discovered that sound travels 【 21】 _ air more than one-half kilometer an hour slower than had been believed. The discovery has surprised many engineers and scientists who learned they had been 【 22】
12、_ the wrong speed of sound for many years. The speed of sound in air had been【 23】 _ to be three-hundred-thirty-one-point-two-nine meters a second. But Doctor George Wong found, 【 24】 _ accident, that the speed of sound is only three-hundred-thirty-one-point-one-three meters a second. That is a diff
13、erence of about sixteen centimeters a second. Doctor Wong is a member of the National Research Council of Canada. He was studying ways to 【 25】 _ exactly the sound created by microph ones.

14、he speed of sound was slower than scientists had thought. To explain the difference, Doctor Wong spent eighteen months 【 28】 _ past test research on the speed of sound. He finally found the 【 29】 _ of the difference. It was a mathematics mistake 【 30】 _ in Nineteen-Forty-Two by physicist H-C Hardy.
15、Doctor Wongs 【 31】 _ does not mean a big change for the science of sound. This is 【 32】 _ Doctor Hardy and Doctor Wong measured the speed of sound for what is called“ standard air“.

22、an visited the troubled Darfur region of western Sudan Thursday to consider ways to end the humanitarian crisis. More than a million people have been displaced in Darfur because of violence that human rights groups blame on government-backed militias. Kofi Annan spoke with tribal and women leaders a
23、bout the problems facing refugees in a camp called Zam-Zam, outside the city of E1-Feshir. The leaders said they were afraid to return home because of possible attacks by the Janjaweed militias. But overall, they said, aid groups were looking after them relatively well in the camp. From there, the s
24、ecretary-general and his delegation went to a camp just 30 minutes away where aid workers said the security and living situation was more desperate. But the refugees were nowhere to be found. U.N. officials said some 4, 000 refugees, called internally displaced persons, or IDPs, had been in the camp
25、 the night before but they had been moved by Sudanese authorities. Jan Egeland, the U. N. s undersecretary-general of humanitarian affairs, said the U.N. did not appreciate the authorities actions. “But it was in our program actually to show the secretary-general and the secretary-general wanted to
26、see how IDPs live when there are no services“ ,“And this was such a place.“ Mr. Egeland was then risked ff this was a deliberate ploy by Sudanese authorities. “Im sure it has happened before and Im sure it will happen again. “The refugees moved to another camp are among the one million people in Dar
27、fur driven from their homes by Janjaweed militias. Human rights groups charge that the ethnic-Arab militias have been used by the government to terrorize the Darfurs civilian population, which is ethnic-African, as part of efforts to put down an armed rebellion. Sudanese authorities deny supporting
28、the Janjaweed and say they are working to disarm them. Until recently, they allowed little access to the region by aid workers. The conflict has given rise to what the U.N. calls the worlds worst humanitarian crisis today. Refugees face hunger, epidemics (传染病 )and continued attacks in camps in Darfu
29、r or over the border in Chad. From Darfur, Mr. Annan flew to Chads capital, Ndjamena, for more discussions on the Darfur crisis.

The leade
35、rs of France and the United States used the occasion to hail the importance of their countries ties, despite deep differences over the Iraq wax. The theme of the day, as outlined by the commemoration host, French President Jacques Chirac, was that modern leaders have the duty to honor what the troop
36、s who took part in D-Day died for, by standing together in the cause of freedom and democracy. Mr. Chirac told an international ceremony in the town of Arromanches, midway along the 100 kilometer stretch of coast where the landings took place, that the men who fought their way onto the beaches of No
37、rmandy set an example for future generations. And he reiterated that France is grateful for Americas coming to its aid in two world wars. “France will never forget what it owes America. “he says,“ And like all the countries of Europe, France is keenly aware that the Atlantic alliance, forged in adve
38、rsity, remains, in the face of new threats, a fundamental element of Europes collective security.“ At an earlier ceremony, President Bush also stressed the importance of bonds that were forged by a common struggle against tyranny. “Our great alliance of freedom is strong, and it is still needed toda
39、y,“ said Mr. Bush. But the emphasis at the ceremonies was on honoring the sacrifice of the men who stormed the beaches 60 years ago, or were parachuted or flown in to support them. One-hundred-forty-two veterans from the 14 countries that took part in the landings marched past the reviewing stand to
40、 thunderous applause. Some used canes. A few were in wheelchairs, but most marched smartly, medals pinned on their chest. President Chirac later gave 14 of them, one from each country, a prized French decoration to add to their collection. This was the first time a German chancellor was invited to a
41、 D-Day ceremony, and Mr. Chirac says the presence of Gerhard Schroeder means once-bitter enemies have put their past behind them. He says Franco-German reconciliation shows the world that hatred has no future and that a path to peace is always possible. A public opinion poll, taken in Normandy, show
42、s that the people of the region overwhelmingly support Mr. Schroeders presence at the D-Day commemorations. And although some Allied war veterans continue to insist that Germany should be kept at arms length, most appear to agree that the world has moved on and, while the bloodshed of World War II s
43、hould not be forgotten, it is time for reconciliation. 46 What does D-day refer to ? （ A） The special day in World War . （ B） The Allied forces landing in Normandy. （ C） The day when Nazi surrendered. （ D） The unnamed day for military offense. 47 Whats the theme of this years commemoration day? （ A）
44、 To pay a poignant tribute to surviving veterans. （ B） To give thanks to American forces coming to help during WWII. （ C） To reconcile with Germans. （ D） To push forward the cause of freedom and democracy. 48 Which of the following is the host country of D-Day ceremony? （ A） France. （ B） The United
45、States. （ C） Germany. （ D） Britain. 49 The leaders of France and the United States _. （ A） differed over the Iraq war （ B） hailed the importance of their ties （ C） promised not to abandon the Atlantic alliance （ D） all of the above 50 How many countries took part in the Normandy Landings sixty years
46、 ago? （ A） l4. （ B） 15. （ C） 16. （ D） 17. 50 Running a fever was once thought to be the prerogative of warm-blooded creatures, whose internal temperatures are independent of the weather. But, as Matthew Kluger reported in “The Importance of Being Feverish“ January 1976, lizards can also develop feve
47、rs, even though there is no question that they are cold-blooded. They raise their temperatures by moving into the sun or, in the case of Klugers experiments, under a sun lamp. And it seems to do them some good. Sick lizards kept in cages at feverish temperatures fare much better than their counterpa
48、rts in normal and cool environments. Now ,fever has spread to invertebrates(无脊椎动物 ). Recent studies have shown that crayfish and scorpions can develop fevers. Crayfish injected with bacteria and scorpions injected with prostaglandins (前列腺素 )swam and scuttled to hot areas. Prostaglandins are hormones
49、 thought to be instrumental in the development of a fever. Evidence is also mounting that moderate fevers have their benefits, which might explain why the fever process is so widespread. Leukocytes, white blood cells that are active in fighting bacterial infections, are more mobile at febrile temperatures. And fevers reduce the amount of iron available to bacteria. That reduction, combined with high temperatures
