    According to Kennett and Christian’s six-year study of Australian freshwater crocodiles’ aestivation, they found aestivating crocodiles spent around【R2】________of the year and had no access to【R3】________. The amount of water in the body declined proportionately with【R4】________; thus there is no sign of【R5】________and other health-damaging impact on the crocodiles even after an aestivation period.

选项
答案hot season／dry season
解析 在鳄鱼栖息的许多地方，大多数种类的鳄鱼进化出一种成功的机制，可以在什么引起的干旱下存活下来。空白处需要填写的是单数名词或名词短语。通过做之前的题目，我们已经知道这种成功的机制说的就是aestivation，通过关键词drought可定位至E段第1句，in many crocodilian habitats对应题干in many places inhabited by crocodilians，从而确定干旱是由hot season引起的。另外，在aestivation第二次出现时，F段开头再次强调了鳄鱼会在dry season进入夏眠。因此，本题的答案为hot season／dry season。
