单选题 It is easy for many kinds of insects to live in the desert because ______.

【正确答案】 D
【答案解析】由题干关键词many kinds of insects定位到最后一段第一、二句Like many desert plants, they have a waterproof skin which prevents water loss because of the high temperature.许多昆虫在沙漠中容易生存下来的原因是它们有一层能防水的皮肤,可以阻止因高温而蒸发体内水分。因此选[D]。[A]、[B]、[C]与文意不符,故排除。
