   Plants are very important  1    things. Life could not go  2    if there were no plants. This is because plants can make food from air, water and sunlight. But animals and man cannot  3    so. Animals get their food by eating plants and  4    animals. Man gets its food by eating plants and animals too.  5    animals and man  6    plants in order to  7    . This is why we find that there are so many plants around us.

   If you look  8    at the plants around you, you will find that there are many types of plants. Some plants are large,  9    others are small.  10    plants are green. There are two sorts(种类)of plants: flowering plants and non-flowering(不开花的)plants.

   Flowering plants have roots(根),stems(茎),leaves, flowers and fruits(果子).  11    all the trees around us are flowering plants. Flowering plants  12    make seeds(种子). The sends  13 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  14    .  15    example of a fruit  16    seeds is banana fruit.

   Most non-flowering plants do not grow from seeds. They grow from spores(孢子). Spores are small. Some spores are  17    small and  18    that they can float(漂浮) 19     the air. We may say that spores are quite different from seeds. When these spores  20    on wet and shady(阴凉的)places, they usually grow into plants.
