Thousands of years ago, in the middle of an ocean, miles from the nearest island, an undersea volcano(火山) broke out. The hot liquid rock piled higher and higher and spread wider and wider. In this way, an island rose up in the sea.As time went on, hot sun and cool rains made the rock split and break to pieces. Sea waves dashed against the rock. In this way, soil and sand came into being.Nothing lived on the naked soil. And then the wind and birds brought plant seeds, spiders and other little creatures there. Only plants could grow first. Only they, in sunlight, could produce food from the minerals of the soil, water and air. While many animals landed on the island, they could find no food. A spider spun its web in vain, because there were no insects for its web to catch, In sects couldn’ t stay until there were plants for them to eat. So plants had to be the pioneer life on this new island.The order of coming into being on the island is（）A. soil, plants and animalsB. soil, little creatures and plantsC. soil, birds and plantsD. soil, human beings and animals

题目解答
答案
A. soil, plants and animals
解析
步骤 1：理解背景信息
火山爆发后，岩浆冷却形成岛屿。随着时间的推移，太阳和雨水使岩石分裂，海浪冲击岩石，形成土壤和沙子。最初，岛上没有生命。
步骤 2：分析植物和动物的顺序
植物是最早在岛上生长的，因为它们能够从土壤、水和空气中产生食物。动物需要植物作为食物来源，因此它们在植物之后出现。
步骤 3：确定正确答案
根据文章内容，土壤首先形成，然后植物生长，最后动物出现。因此，正确答案是土壤、植物和动物。
