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 do so. Animals get their food by eating plants and other animals. Man gets his food by eating plants and animals, too. Therefore, animals and man need plants in order to live. If you look carefully at the plants around you, you will find that there are many types of plants. Some plants are large while others are small. Most plants are green. There are two main types of plants: flowering plants and nonflowering plants. Flowering plants have roots, stems①, leaves, flowers and fruits. Almost all the trees around us are flowering plants. You can probably recognize some plants from their flowers or their fruits. Nonflowering plants include coniferous trees, mosses, liver-worts, algae and fungi. You cannot see many nonflowering plants around you. Most plants do not grow from seeds. They grow from spores. Spores are very, very small. Some spores are so small and light that they can float in the air. We may say that spores are quite similar to seeds. When these spores fall on wet and shady② places, they usually grow into new plants. 【词语解释】 ①stem [stem] n． 茎；（树）干；（叶）梗 ②shady[’sheidi] a．背阴的；阴凉的 During millions of years of evolution2, ants have developed intriguing3 relationships with many different kinds of plants.Most of these associations4 are loose ones -- the ants find dwelling5 places on the plants,while bringing neither harm nor benefit to them. Often the ants live in hollow dead stems or small pockets of soil that accumulate6 on branches. Thus ants inhabit trees over our heads and herbs at our feet,carving out living chambers7 and foraging8 for food. As many as 72 different species of ants have been found living on one tree in Peru's Amazon Basin alone. 注释： 1．profitable adj．有益的，有用的 2．evolution n．[生]进化，进化论 3．intriguing adj．引起好奇心(或兴趣的)，有迷惑力的 4．association n．友谊，伙伴关系 5．dwelling n．住处，住宅，寓所 6．accumulatevt．堆积，积聚 7．chambern．室，寝室 8．forage vi．搜寻 经过几百万年的进化，蚂蚁与多种不同植物形成了十分有趣的关系。其中大多数关系并不紧密：蚂蚁在植物上寻找居所，而并不给植物带来利和害。蚂蚁经常栖于中空的植物枯茎或枝干上堆积的小土坑中。因此，我们头顶的树木和脚下的草丛中都住着蚂蚁，它们在那儿建造居室或搜寻食物。仅在秘鲁的亚马逊流域，一棵树上住的蚁类就达72种之多。 Dear Editor; We often say such a word: Life comes from water.And as is known to all, we mostly live on the sea, which ,for human, is a most important resourse of both food and production. However, it is obvious that every year various sea living things are getting less and less in large quantities. Some species have died out and some are coming to that. What causes this? The overusage of the resourses and the pollution of the waters should account for that, I think. If we don't yet do anything to deal with these, we'll be sure to lose at least half of our life. So I expect the whole world would pay more attention to the problem of sea livings. 现象：海洋动植物的数量正在减少，有些物种甚至灭绝了 原因：过度利用 水质污染 结论：海洋环境问题亟需关注
