　　31．C；根据原文All living things need energy to live and grow．This energy comes first from the sun．所有生物需要能量去生存和成长．这些能量首先来自太阳．所以选C．　　32．D；根据原文Kangaroo rats keep cool by coming out only at night to look for food．Ringtail cats also come out only at night．Ringtail cats hunt and eat kangaroo rats．浣熊猫也晚上出没是因为吃跳囊鼠，跳囊鼠晚上出没．所以选D．　　33．B；根据原文Vultures eat dead animals．Vultures are scavengers．食腐动物吃死了的动物的尸体．看图片中，既吃跳囊鼠，浣熊猫，土狼的就是，食腐动物秃鹫了．所以选B．　　34．B；根据上下文，A，C，D都是正确的，B选项植物在食物链的最顶端是错的，应该是食腐动物，植物应该处在最底层．所以选B．　　35．A；根据A food web shows how food chains work together及文章大意可知文章主要讲了生物网的构成及如何运作，所以选A．
