　　引证题

　　引证题是指对关于于文章中作者引用别人的话或是名言，或是他人的观点等等而设置的问题。做此类题一定要注意看作者所引用的观点与作者自己的观点是否一致，如果一致，可从整篇文章的思路推理，如不一致，可从文章的反向考虑。我们在答此类题时，一定要返回原文，仔细比较。例如：

　　Why don’t birds get lost on their long migratory(迁徙的) flight? Scientists have puzzled over this question for many years. Now they are beginning to fill in the blanks.

　　Not long ago, experiments showed that birds rely on the sun to guide them during daylight hours. But what about birds that fly mainly by night? Tests with artificial(人造的) stars have proved conclusively that certain night-flying birds are able to follow stars in their long-distance flights.

　　One such bird─a warbler─had spent its lifetime in a cage and had never flown under a natural sky. Yet it showed an inborn ability to use stars for guidance. The bird’s cage was placed under an artificial star-filled sky at migration time. The bird tried to fly in the same direction as that taken by his outdoor cousins. Any change in the position of the artificial stars caused a change in the direction of his flight.

　　Scientists think that warblers, when flying in daylight, use the sun for guidance. But stars are apparently their main means of directed flight in the night. What do they do when stars are hidden by clouds? Apparently, they find their way by such landmarks as mountain ranges, coast lines and river courses. But when it is too dark to see these, the warblers circle helplessly, unable to find their way. (2005年12月浙江省大学英语三级考试题)

　　What does the passage say about warblers’ sense of direction?

　　A. They are not able to see clearly at night.

　　B. They get lost under star-filled sky.

　　C. They lose their way when it is too dark.

　　D. They usually depend on clouds for direction.

　　在此篇文章中，作者首先引用了科学家的观点，即鸟在白天靠太阳导航;接

　　着又引用科学家的观点，提到鸟在夜晚靠星星导航。在文章的最后一部分，作者提到在乌云遮住星星的晚上，鸟靠地标导航;但是，当夜晚太黑的时候，鸟看不到地标，就无可奈何了，只好在空中盘旋。不管文章的最后部分是作者的观点，还是作者引用科学家的观点，但最后部分却是作者同意的观点。C项是对有关次嘴莺方向感的正确表述，为正确选项。
