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. They get their food by eating plants and other animals. If you look carefully at plants around you, you will find there are two kinds of plants: flowering plants and non-flowering plants.
Flowering plants can make seeds(种子). The seeds are guarded by the fruits. Some fruits have one seed, some have two, three or four, and some have many. 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(漂浮) in the air. We may say that spores are quite the same as seeds. When these spores are all on wet and sandy places, they usually grow into plants.

解析试题分析：这篇短文中作者主要介绍了植物在自然社会生活中的重要作用，并且重点介绍了两种不同的植物，即开花的植物和不开花的植物以及各自的特点。
【小题1】主旨大意题。根据第一段的前两句话可知植物对于生命是很重要的，接着给出了原因，植物能够利用空气、阳光和水制造食物，所以答案选A。
【小题2】细节理解题。根据第二自然段If you look carefully at plants around you, you will find there are two kinds of plants: flowering plants and non-flowering plants. 如果你仔细观察一下我们周围的植物，你将会发现有两种植物：有花的植物和没花的植物。故答案选C。
【小题3】推断词义题。结合常识可知，有果实的植物种子往往在果实内部，果实起着保护种子的作用。所以protected应是“保护”的意思，有guarded相近。故选B。
【小题4】推理判断题。通读全文可知，植物能够利用空气、阳光和水制造食物，动物不能制造食物，只能吃植物或动物，离开了植物，动物包括人类都要死亡，故选D；根据最后一自然段的描述可知A,B和C都是错误的。
