We must do what we can to protect the plants because plants are very important for 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.

Is there a magic cutoff period when children become responsible for their own actions? Is there a wonderful moment when parents can become spectators in the lives of their children and shrug, “It’s their life,” and feel nothing?

  When I was in my twenties, I stood in a hospital passage waiting for doctors to put a few stitches(缝线) in my son’s head. I asked, “When do you stop worry?” The nurse said, “When they get out of the accident stage.” My mother just smiled faintly and said nothing

   When I was in my thirties, I sat on a little chair in a classroom and heard how one of my children talked continually and disrupted the class. As if to read my mind, a teacher said. “Don’t worry, they all go through this stage and then you can sit back, relax and enjoy them” My mother just smiled faintly and said nothing.

  When I was in my forties, I spent a lifetime waiting for the phone to ring, the cars to come home, the front door to open. A friend said, “ They’re trying to find themselves, Don’t worry, in a few years, you can stop worrying. They’ll be adults.” My mother just smiled faintly and said nothing.

  By the time I was 50, I was sick and tired of being weak. I was still worrying over my children, but there was a new wrinkle, there was nothing I could do about it. My mother just smiled faintly and said nothing.

 I continued to suffer from their failures, and be absorbed in their disappointments. My friends said that when my kids got married I could stop worrying and lead my own life. I wanted to believe that, but I was haunted(萦绕心头) by my mother’s warm smile and her occasional “You look pale. Are you all right?” Call me minute you get home. Are you depressed about something ?” Can it be that parents are sentenced to a lifetime of worry?

 One of my children became quite anxious about me recently, saying, “ Where were you ? I’ve been calling for three days, and no one answered . I was worried.”

  I smiled a warm smile
