题目内容
【题目】Plants are very important living things. Life could not go on if there were no plants. This is because plants can make food from air, water and sunlight. Animals and man cannot make food from air, water and sunlight. Animals get their food by eating plants and other animals. Therefore animals and man need plants in order to live. This is why we find that there are so many plants around us.
If you look carefully at the plants around you, you will find that there are two kinds of plants: flowering plants and non-flowering plants. Flowering plants can make seed. The seeds are protected by the fruits. Some fruits have one seed, some have two, three or four, and some have many seeds. But a few fruits have no seeds at all. An example of a fruit without seeds is the banana fruit. Most non-flowering plants do not grow from seeds. They grow from spores (胚芽). Spores are very small. Some spores are so small and light that they can float in the air. We may say that spores are quite the same as seeds. When these spores are all on wet and shady places, they usually grow into new plants.

【解析】
试题分析:这篇文章植物对各种生物的重要性以及植物的分类。
【1】A段落大意题。文章第一段第一句就开门见山的向我们表达了植物对生活的的重要性,后面的描述是为了支撑这个观点。故选A。
【2】B细节理解题。定位到文章第一段This is because plants can make food from air, water and sunlight,从此句我们可以得知植物是从空气、水和阳光制造有机物的。可判断B正确。
【3】D推理判断题。使用排除法,A中有all、most表绝对的词,排除A。从We may say that spores are quite the same as seeds.这句话可知胚芽和种子只是作用类似的东西,胚芽并不是种子,故B不正确。文中提到香蕉是没有种子的水果,可以排除C。全文向我们表达了植物对于生活、人类甚至各种生物的重要性,言下之意也就是没有植物,人类将不能生活下去。故选D。
【4】C推理判断题。本文主要是讲植物这种生物,根据常识这篇文章最有可能截取自一本科学杂志。故选C。
