Asia-Pacific Economic Cooperation(APEC) members met in Beijing from November 5 to 11 to discuss the future of APEC and the overall development of the Asia-Pacific area. APEC, which was set up in 1989,is a forum for 21 member countries to develop free trade and economic cooperation throughout the Asia-Pacific area. Though Asia-Pacific Economic Cooperation came to a successful close, the "APEC Blue" has become popular in Beijing, even in China. A clear blue sky in Beijing is difficult to see during the smog season, so Beijingers gave it a name: "APEC Blue". "Oh, how beautiful the autumn sky is and how fresh the air is!" This is how most Beijingers feel during APEC. "I hope the APEC Blue will remain, and I believe, through the efforts we continue to make, it will." A lot of environmentally friendly ways were taken to reduce the Beijing smog during the APEC meeting, including limiting the number of cars on the road, stopping some factories in neighboring cities and so on. Perhaps we can learn something from London, where the Great Smog killed 4,000 people :in four days in 1952. Britain then passed its first air pollution act, which required that all power plants in London should be shut down, factories must build taller chimneys, and the heating system must be improved. In order to keep "APEC Blue", Beijing plans to build air corridors to blow away pollution. Not all agree with this way. Song Guojun, a professor of _ at Renmin University, believes that this way will not solve the problem at its root, and only by controlling the source of pollution will Beijing see bluer skies. The "APEC Blue" was named by _ . A) APEC B) people in China C) Beijingers D) 21 countries

*Question*
"Listen carefully to what I say," the time traveler said, "I shall tell you something that you will not agree." "Why will we not agree?" I asked. "Because the science and mathematics you know are not correct," he said. "You believe there are only three dimensions -length, breadth and thickness." "There is nothing to argue with that, " the youngest member of our little group said. "Exactly!" the time traveler answered, "But there is also a fourth dimension - time." "We all know about time, " another member of the group said. "Time passed." "I do not agree," the time traveler said, "Length, breadth and thickness do not pass. They stay in the same place in space. We move about them. I can prove that time is the same. It does not pass. We move in time the same way that we move in breadth, length and thickness." None of us believed the time traveler, and we argued with him for many hours. "If we could travel back in time," the scientist said, "We could do things to change the future." "If we could travel forward in time," the doctor said, "we could do things that change our present." The time traveler smiled, "It is clear," he said, "that there is only one way I can show you that I am right. We must do an experiment. Please wait here." He left the room and soon returned, carrying what looked like a clock. "This is a model of a time machine. It took me two years to make it," the time traveler said. "I want all of you to understand that when I start the machine, it will immediately travel in time and disappear from the present." He turned to the youngest of all. "Give me your hand," he said. The young man put out his hand. The time traveler took it and placed it on the machine. Immediately, there was a sudden wind, and the little machine disappeared. I was certain this was not a trick, but the doctor was not so sure. "Are you asking us to believe," he said, "that the machine is now in a different time?" "Certainly! In my laboratory, a full-size machine is almost complete. As soon as it is complete, I shall... How many dimensions did the time traveler say there are? A) Two. B) Three. C) Four. D) Five.
