托福口语 Task 4

Today, we're going to talk about a fascinating concept in biology called 'behavioral adaptation'—specifically, how some animals have developed clever strategies to cope with extreme environments. One key point is that these adaptations are not physical changes but learned or instinctive behaviors that increase survival. Let me give you two examples. First, consider the desert kangaroo rat. It lives in arid regions where water is scarce. Instead of drinking water, it obtains moisture from the seeds it eats and avoids overheating by staying in its burrow during the day, only coming out at night when it's cooler. This nocturnal behavior is a classic adaptation. Second, think about the Arctic fox. In winter, food is hard to find. The fox has developed a hunting technique where it listens for small rodents under the snow, then leaps into the air and crashes down through the snow to catch them. This precise hunting behavior helps it survive the harsh winter. So, the main point is that these behavioral adaptations are crucial for animals to thrive in challenging habitats.
