我肯定在原文中的句子是这一句
Thus, in the trees, where shelter from heat and cold may be scarce and conditions may fluctuate, a small mammal may have trouble maintaining its body temperature.
问题是 According to the paragraph,which of the following is ture about the small mammals in the rain forest?
A They have body shapes that are adapted to life in the canopy
B They prefer the temperature and climate of the canopy to that of other ebviroments
C They have difficulty with the changing conditions in the canopy
D They use the trees of the trees of the canopy for shelternfrom heat and cold
答案是D ,但是觉得是C 文中的conditions may fluctuate不就是chianging condition 的意思吗?为什么会是D呢?文中不是说shelter may be scarce,不就是说没有shelter吗?
