判断题 Migratory birds may rely on the earth’s magnetic field for guidance while traveling during cloudy days.（）
对
错
正确答案：错
答案解析: 逻辑推理和判断。录音中指出“On cloudy nights,they may be using the earth’s magnetic field…”，可知，多云的夜晚，迁徙的鸟类在飞行时会依靠地球磁场的指引，而非题干中所提到的during cloudy days。因此该题表述有误。
【录音原文】Migratory birds use several ways to help them navigate . While traveling on a clear night they use the stars as guides. On cloudy nights, they may be using the earth’s magnetic field or the wind to help them navigate accurately. While flying during the day, the sun provides help for their precise flight.
