问题     Thousands of years ago, in the middle of an ocean, miles from the nearest island, an undersea volcano broke out. The hot liquid got 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 hit 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 living things there. Only plants could grow first. Only they, in sunlight, could produce food from the soil, water and air. While many animals landed on the island, they could find no food. A spider made its web uselessly, because there were no insects(昆虫)for its web to catch. Insects couldn’ t stay until there were plants for them to eat. So plants had to be the first life on this new island.
According to the passage, which of the following is TRUE?
选项 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.
答案C
解析 根据上题可知，A项不正确，B项文中并未提及．D项根据第三段第二句话，植物是由风和小鸟带来的，所以也不正确，根据排除法，选C。
