题目
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.According to the passage, which of the following is true（） A. Spiders were the first life that could live on the island.B. The island is far away from any piece of land.C. Insects could not live on the island without plants.D. Plants were brought to the island by human beings.

题目解答
答案
C
解析
步骤 1：理解背景信息
文章描述了一个海底火山爆发后形成的新岛，随着时间的推移，太阳和雨水使岩石分裂，海浪冲刷岩石，形成了土壤和沙子。最初，岛上没有生命，后来风和鸟类带来了植物种子、蜘蛛和其他小生物。植物是最早能够生长的，因为它们能够从土壤中的矿物质、水和空气中产生食物。许多动物来到岛上，但找不到食物。蜘蛛织网也无济于事，因为没有昆虫可以捕获。昆虫不能在岛上生存，直到有植物供它们食用。因此，植物是新岛上最早的生命形式。
步骤 2：分析选项
A. 蜘蛛是最早能生活在岛上的生命形式。
B. 这个岛远离任何陆地。
C. 没有植物，昆虫不能在岛上生存。
D. 植物是由人类带到岛上的。
步骤 3：选择正确答案
根据文章内容，选项C是正确的。文章明确指出，昆虫不能在岛上生存，直到有植物供它们食用。因此，没有植物，昆虫不能在岛上生存。
