单选题We arranged that Kissinger would fly to Vietnam for talks early in July and then stop in Pakistan on the way back. There he would develop a stomachache that would require him to stay in bed and not be seen by the press. Then, with President Yahya"s cooperation he would be taken to an airport where a Pakistani plane would fly him over the mountains to China. Kissinger"s trip was given the code (密码) name Polo after Marco Polo, another Western traveler who made history by journeying to China. Everything went without a hitch. His slight illness in Islamabad received only minor attention from reporters covering him. They accepted the story that he would be confined to bed for at least a couple of days and began making arrangements for their own entertainment. Because of the need for complete secrecy and the lack of any direct communication facilities between Beijing and Washington, I knew that we would have no word from Kissinger while he was in China. Even after he had returned to Pakistan it would still be important to maintain secrecy. So before Kissinger left, we agreed on a single code word—Eureka—which he would use if his mission were successful. On July 11, A1 Haig, who knew our code word, phoned me to say that a cable from Kissinger had arrived. "What"s the message?" I asked. "Eureka," he replied.

单选题{{B}}Passage One{{/B}} Although no one is certain why migration occurs, there are several theories. One theory claims that prehistoric birds of the Northern Hemisphere were forced south during the Ice Age. As the glaciers melted, the birds came back to their homelands, spent the summer, and then went south again as the ice advanced in winter. In time, the migration became a habit in spite of the disappearance of glaciers. Another theory proposes that the ancestral home of all modern birds was the tropics. When the region became overpopulated, many species were crowded north. During the summer, there was plenty of food, but during the winter, scarcity forced them to return to the tropics. A more recent theory suggests a relationship between increasing daylight and the stimulation of certain glands(腺)in the birds' bodies that may prepare them for migration. One scientist has been able to cause midwinter migrations by exposing birds to artificial periods of daylight. He has concluded that changes occur in the bodies of birds due to seasonal changes in the length of daylight.
