　　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．

　　Everyone knows the story of Benjamin Franklin's famous kite experiment．He was a man of many gifts and interests．His natural curiosity(好奇心)about things made him try to find ways to make them work better．Although he made important discoveries, Ben didn't“invent”electricity．He did, however, invent the lightning rod(避雷针)which protected buildings and ships from lightning damage．

　　In America, most people warmed their homes by building a fire in a fireplace even though it was kind of dangerous and used a lot of wood．Ben said that he had another better way．His invented an iron stove which allowed people to warm their home less dangerously and with less wood．The stove that he invented is called a Franklin stove．Ben also set up the first fire company and the first fire insurance company in order to help people live more safely．

　　As the postmaster, Ben had to find out the best way for delivering(发送)the mail．He went out riding in his carriage(马车)to measure(测量)the routes and needed a way to record the miles．He invented a simple odometer for it．

　　In his old age, Ben retired from business and public service and wanted to spend his time reading and studying．He found, however, that his old age had made it difficult for him to reach books from the high shelves．Even though he had many grandchildren to help him, he invented a tool called a long arm to reach the high books．The long arm was a long wooden pole with a grasping claw at the end．

　　Later, other famous inventors, like Thomas A．Edison and Alexander Graham Bell, would follow in Ben's footsteps by trying to find ways to help people live better．Today's curious thinkers are keeping Ben's traditions alive by inventing new and improved ways to make things work．
