托福口语 Task 4

Today, we're going to talk about a fascinating concept in animal behavior called 'behavioral flexibility'. This refers to an animal's ability to adapt its behavior to new or changing circumstances, rather than relying solely on instinct. Behavioral flexibility is crucial for survival, especially when environments change rapidly. Let me give you two examples. First, consider the raccoon. Raccoons are known for their intelligence, but they also show remarkable flexibility in their foraging habits. In urban areas, where natural food sources are scarce, raccoons have learned to open trash cans and even doors to access food. This is not a behavior they are born with; they figure it out by trial and error, and they adapt quickly to new human environments. Second, think about the mountain goat. These goats typically graze on grassy slopes. However, when food becomes scarce in winter, they have been observed climbing down to lower elevations and even eating seaweed on the beach—a behavior not typical of their species. This flexibility allows them to survive in harsh conditions. So, behavioral flexibility is not just about having a wide diet; it's about problem-solving and adjusting to novel situations.
