Question

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 seeds. 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：本文主要讲了植物是一种非常重要的生物，一切生命都不能离开植物。通过植物与人和动物的比较得出，植物是自养型生物，而人和动物是非自养型生物。植物主要有两大类：花型植物和非花型植物。花型植物依靠种植繁殖，非花型植物依靠胚芽繁殖。

1. are very important living things. Life could not go on if there were no plants.接下来整篇文章就这两句话进行论证，说明植物对其他生物的重要作用。故选A。

2. is because plants can make food from air，water and sunlight可知，植物可以通过空气、水和阳光自己产生食物。故选B。

3. could not go on if there were no plant可知若没有植物，那么生命也将无法继续。整篇文章只在第一句说道植物是一种很重要的生物，并没有提到所有的生物，A错；由文章第九到十二句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可知，有的植物有种子，而有的植物没有种子，例如香蕉有果实却没有种子，C错；由文章第十三到十四句Most non-flowering plants do not grow from seeds. They grow from spores（胚芽）。可知，无花植物不是通过种子繁殖，而是通过胚芽来繁殖，可以得出，胚芽不是种子，D错。故选B。
