程海亮回答:
  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.
