题型分类：推论题

原文定位：根据natterjack定位到“the natterjack toad”这一句。

选项分析：

C选项：第二句说在North of the Pyrenees Mountains的the natterjack toad冬天要冬眠。Conversely（与之相反）natterjacks in southern Spain夏季要夏眠。所以C选项符合。

A选项：原文单独讲到夏眠和冬眠，没有进行比较，无中生有。

B选项：Desiccation is not a threat 与forced into inactivity during the dry, hot summer season矛盾。

D选项：原文只提及冬季和夏季，与active only in the spring and in the fall矛盾。
