专升本英语真题练习与答案解析

    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 ?rst. Only they, in sunlight, could produce food from the soil, water and air. While many animals landed on the island, they could?nd no food.

    真题详细答案解析：

    1. D. 主旨题。全文主要在讲述在一个火山形成的小岛上生命是怎样起源的。

    2. C. 细节题。在文章的第二段的最后一句，说到海浪拍打岩石，通过这种方式，形成了土壤和沙子。

    3. D. 词义题。在文章的第三段第一句，通过nothing知道在岛上是没有任何生命迹象的，那么这种土壤一定是光秃秃的，裸露的，所以答案应该选D，bare(裸露的)正符合此意。

    4. A. 细节题。从文章的最后一段可以知道，在小岛上各种东西出现的顺序是先有土壤，然后有了植物，最后才是动物。

    5. C. 细节题。排除法找出一个正确的。A选项说蜘蛛是第一个可以在小岛上生存的生物是错误的，文章的最后一句告诉我们说小岛上的第一个生物是植物，蜘蛛不属于植物，所以A选项不对。B选项说小岛远离任何一个岛屿，有any太绝对了，所以也不正确。C选项说没有植物任何昆虫都是无法生存的是正确的，因为文章中说到植物可以给昆虫提供食物。D选项说是人类把植物带到小岛上的是错误的，文章最后一段刚开始给出是鸟类和风把植物的种子带到岛上的。
