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(不開花的) plants.
Flowering plants can make seeds(種子). 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(孢子). 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 the same as seeds. When these spores fall on wet and shady(陰涼的) places, they usually grow into new plants.

How to be a Green One
What does it mean to be green? “Green is more than just a c 76 .It also means taking special steps to protect the e77 --the water, the land , and the air we breathe. Why is green? Plants are green, and w78 them the earth wouldn’t be such a lovely home for human beings(人類). Here’s a four-step guide to be green:
R79 It!
When you use less of something, you do a good thing for the earth. For example, a shorter shower means you use less water and less fuel(燃料) because your house uses fuel to run the water heater(加熱器)that warms up the water.
Reuse It !
Sometimes we’re a little too willing to throw away the w80 and buy new things. Many times, you no l 81 need something, someone else just might need it. For example, if your baby brother grows out of toys, why not give them to a82 family who has a little kid?
Recycle(回收) It!
Recycling has n83 been easier. Many people will pick it up right in front of your house and they will need it. Tell your mum or dad become “Head of Recycling” for your house.
Enjoy It!
It’s true that p84 is a problem, but the earth is still a large and beautiful place for you to go and study. You can start by v85 the beautiful places in you home town. Go for a hike, visit local nature centres and gardens, climb up mountains and so on.
