TPO11-2 Orientation and Navigation
Paragraph 6
What about birds that migrate at night? Perhaps they navigate by the night sky. To test the idea, caged night-migrating birds were placed on the floor of a planetarium during their migratory period. A planetarium is essentially a theater with a domelike ceiling onto which a night sky can be projected for any night of the year. When the planetarium sky matched the sky outside, the birds fluttered in the direction of their normal migration. But when the dome was rotated, the birds changed their direction to match the artificial sky. The results clearly indicated that the birds were orienting according to the stars.
11. Which of the following best describes the author's presentation of information in the passage?
○ A number of experiments are described to support the idea that birds use the Sun and the night sky to navigate.
○ The author uses logic to show that the biological clock in birds is inaccurate.
○ A structured argument about the importance of internal versus external cues for navigation is presented.
○ The opposing points of view about bird migration are clarified through the study of contrasting experiments.
解析：修辞目的题，问整段的，所以看首句，说鸟是靠night sky定位的，尾句又说是靠星星，所以这段应该在说鸟在夜间定位的方法，前几段都在说白天鸟用太阳定位，所以综合起来，答案是A，分别叙述鸟在日间和夜间的定位方法
[6]那些在夜间迁徙的侯鸟又是怎样的呢?也许它们通过观察夜晚的天空来定向飞行。为了证实这一推测，把在夜间迁徙的侯鸟关进笼子里，并在它们的迁徙的时间段，将笼子置于一个天文馆的地板上。这个天文馆实际上是一个剧场，天花板呈穹顶状可以投射出一年四季所有夜晚的景象。当天文馆的穹顶与外面的天空相吻合时，这些鸟就会朝着往常迁徙的方向拍打着翅膀。但是当穹顶旋转时，这些鸟就会改变方向以适应这个人造天空。这就清楚地表明这些夜间迁徙的侯鸟是通过星宿位置来定位方向。
以上就是托福阅读TPO11-2中的修辞目的题及其解析，大家可以在备考的时候参考复习，希望能够帮助大家的考前准备。最后前程百利祝大家都能取得理想的托福考试成绩。
