问题 The most important environmental influence on fish is water temperature, for fish tend to ______ the temperature of their surroundings.

选项 A、avoid
B、exceed
C、assume
D、regulate

答案 C

解析 assume“呈现(某种形式)”，“接受”；avoid“避免”，“防止”；exceed“超过”，“越出”；regulate“调整”，“调节”，多用于调整速度、调节热量等，本题意为：“最影响鱼的是水温。而鱼类仅是本能地适应其周围水域的温度。”因此，C是正确答案。
