All plant cells are capable of taking up water. Even dead ones do to a certain degree. Absorption(吸收)of water by dead cell walls makes wood become larger. In common land plants, the living cells of roots take up most of the water. Land plants without roots do exist, however. Those greenish-yellow lichens(苔藓)you see on rocks in the high mountains have no roots. Half a billion years ago, when water plants started to enter the land, the first land plants did not have roots.

Even among the flowering plants, one finds rootless forms. These flowering plants are “the higher plants” because they evolved(进化)recently and are thus considered higher on the evolutionary scale(进化度). In the Peruvian desert, there grows one of these rootless higher plants, a bromeliad. It is a relative of the pineapple. Even if this plant had roots, they would be of no use, because where the plant grows, it never rains. The plant gets its water only from the dew(露水)it collects at night, when its leaves cool off. Such rootless plants, of course, can be moved with ease, but they will only grow when they are placed out in the open. If they are placed too near a house, the radiation from the heat of the house prevents the leaves from cooling and so prevents dew from forming, and the plant dies. In the southern United States and in Puerto Rico, one sees bromeliads growing high above the streets on the insulation(绝缘物)of electric wires. These plants get their water from rain, and the only soil they ever come in contact with is the dust that may blow on their leaves.

Introduction to Letters to Sam

Dear Reader,

     Please allow me to tell you something before you read this book. When my   36 , Sam, was born, my heart was filled with joy. I had been sitting in a wheelchair for 20 years before then, and I have been  37  ill many times. So I wondered if I would have the  38  to tell Sam what I had  39  .

     For years I have been hosting a program on the  40  and writing articles for a magazine.  Being  41 to move freely, I have learned to sit still and keep my heart  42 , exchanging thoughts with thousands of listeners and  43  . So when Sam was born, I  44  to tell him about school and friendship, romance and work, love and everything else. That’s how I started to write these  45 . I hope that Sam would  46  them sooner or later.

     However, that expectation  47  when Sam showed signs of autism (自闭症) at the age of two. He had actually stopped talking before the discovery of the signs. He  48  to communicate with others, even the family members. That was  49  for me but didn’t stop me writing on. I realized that I had even   50  now to tell him. I wanted him to  51  what it means to be “different” from others, and learn how to fight against the misfortune he’ll  52  as I myself, his grandfather, did. I just  53  if I could write all that I wanted to say in the rest of my life.

     Now,   54  the book has been published, I have been given the chance. Every chapter in the book is a letter to Sam: some about my life, and all about what it means to be a   55  .
