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】

試題分析：本文主要講了植物是一種非常重要的生物，一切生命都不能離開(kāi)植物。通過(guò)植物與人和動(dòng)物的比較得出，植物是自養(yǎng)型生物，而人和動(dòng)物是非自養(yǎng)型生物。植物主要有兩大類：花型植物和非花型植物。花型植物依靠種植繁殖，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.接下來(lái)整篇文章就這兩句話進(jìn)行論證，說(shuō)明植物對(duì)其他生物的重要作用。故選A。

2. is because plants can make food from air，water and sunlight可知，植物可以通過(guò)空氣、水和陽(yáng)光自己產(chǎn)生食物。故選B。

3. could not go on if there were no plant可知若沒(méi)有植物，那么生命也將無(wú)法繼續(xù)。整篇文章只在第一句說(shuō)道植物是一種很重要的生物，并沒(méi)有提到所有的生物，A錯(cuò)；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，有的植物有種子，而有的植物沒(méi)有種子，例如香蕉有果實(shí)卻沒(méi)有種子，C錯(cuò)；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）�？芍�，無(wú)花植物不是通過(guò)種子繁殖，而是通過(guò)胚芽來(lái)繁殖，可以得出，胚芽不是種子，D錯(cuò)。故選B。
