Question: Read the following article and select the best answer. Article: Put yourself in these tourists' position. You are walking an icy mountain path in the Alps in Europe. Suddenly you spot a body on the ground,face downward and stuck to the ice. You think someone may have been murdered or in an accident. So you rush back and call the police. The police,however,quickly realize that this body is different from others they've found on the mountain. For one thing,it is mostly undamaged. For another,its skin is dried out,like a mummy's. And with it is a knife with a small stone knife. The body turned out to be much older than the tourists could have guessed. When specialists had a chance to examine it,they discovered it had been there for about five thousand years! How could a body stay preserved for all this time?Two things probably helped. First,the place where the man died was somewhat sheltered,so animals couldn't get at it. Then he was quickly covered by falling snow. Wind blowing through the snow probably "freezedried" his body,removing all _ from it. Objects found with the body told something about the Iceman's life. He wore a thick fur overcoat and trousers. He clearly had been hunting,for he carried arrows,and animal bones were nearby. He also had a grass cushion for sitting or sleeping on. Perhaps he was exhausted when he lay down for the last time. The body was found in 1991,when some of the ice on the mountain melted. Searching for the cause of the Iceman's death,scientists put the body back into cold conditions and hoped... Question: The time of the year that the Iceman died was probably _ . - early fall - late spring - summer - winter
Answer: winter

Question: Read the following article and select the best answer. Article: "We don't have rush hours any more", said Mr. Charles Mac Lean, who runs the nation's busiest road. "We have rush periods, and they keep getting longer and longer." Mac Lean was describing prefix = st1 /Chicago's 235 miles of expressway. But the same might be said about almost any of the expressways that have become an important part of American city life--and about the heavy traffic that often blocks them. In Chicago, a computerized system has been developed that controls traffic on the city's seven expressways. Now one man--a controller--can follow the movement of Chicago's traffic by looking at a set of lights. The system uses electronic sensors that are built into each expressway, half a mile apart. Several times a second, the computer receives information from each sensor and translates it into green, yellow, or red lights on a map in the control room. A green light means the traffic is moving forty-five miles an hour, yellow means thirty to forty-five miles an hour and red means heavy traffic--cars standing still or moving less than thirty miles an hour. "See that red light near Austin Avenue?" the controller asked a visitor. "That's a repair truck fixing the road, and the traffic has to go around it". At the Roosevelt Roadentrance to the expressway, the light kept changing from green to red and back to green again. "A lot of trucks get on the expressway there," the controller explained. "They can't speed up as fast as cars." The sensors show immediately where an accident or a stopped car is blocking traffic, and a truck is sent by radio to clear the road. The system has lowered the number of accidents by 18 percent. There are now 1.4 deaths on Chicago's expressways for each one hundred million miles traveled, while in other parts of the country there are 2.6. Traffic experts say that the Chicagosystem is the "coming thing". Systems like Chicago's are already in use on some expressways in Los Angeles andHouston. "Chicago has taken the lead," saysNew York City's traffic director; and he adds, "We are... Question: How does the controller follow Chicago's traffic? - By controlling the traffic lights. - By operating a computer in the control room. - By sending a truck to clear the roads. - By looking at a set of lights on the map in the control room.
Answer: By looking at a set of lights on the map in the control room.

Question: Read the following article and select the best answer. Article: BEIJING, Oct. 13 (Xinhuanet) -- A recent sudden temperature drop in most areas of China has set off fears of a possible return of severe acute respiratory syndrome (SARS) and the country has mobilized to prepare for another outbreak. North China's Tianjin Port resumed a temperature reporting system on Sunday. Any passengers through the port with a temperature above 38 degrees Celsius would be provided medical observation and reported to relevant authorities. Zhong Nanshan, a well-known anti-SARS scientist during the last outbreak, said it was unlikely the SARS virus would die out naturally and it would definitely come back, but predicted no widespread epidemic outbreak and the epidemic would not cause serious damage again. Caught unprepared this spring, Chinese authorities have learned to act quickly before the epidemic can take a hold. Chinese Vice-Premier Wu Yi Thursday urged strictly implementing the daily SARS epidemic reporting system and warned that people delaying reporting or hiding the true situation would be severely punished. In Beijing, the disease control center in Dongcheng District has recovered a 24 hour schedule for possible epidemic breakout. Every afternoon before 3:00 o'clock, the center receives SARS reports from every hospital in the district and then reports to the Beijing municipal disease control center and health bureau. In Beijing Xiehe Hospital, plans are ready for fever patients to receive treatment in a special section. Doctors in that ward, wearing protective clothing, will observe patients for any possible respiratory diseases. Patients with high fever and symptoms of respiratory diseases are required to be observed for one or two weeks. North China's Shanxi Province and Inner Mongolia Autonomous Region, the two other hardest-hit areas in the last SARS crisis, have both set up an emergency response mechanism and mobilized all concerned departments. The system has also been set up in rural Inner Mongolia. People are urged to pick up again the healthy habits they formed during... Question: This passage is mainly about _ . - Zhong Nanshan, a well-known anti-SARS scientist - What happened during the first outbreak of SARS - How well China is prepared for another likely outbreak of SARS - What hospitals in Beijing have done
