  被认为是北美最凶猛的响尾蛇常常是自然学家研究和讨论的对象。它名字的由来是源于尾部因蜕皮（脱下旧皮）时残留下的环状的硬皮。一旦响尾蛇被激怒，就会头动它的尾部，这就使得环状硬皮发出了响声。

  大多数自然学家都认为这种声音是爬行动物在紧张时一种不自觉的反映，他们并不认为响尾蛇是在试着想它可能的进攻对象传达一种警告。研究表明响尾蛇是毒蛇中{wy}一种在进攻前发出信号的。并且事实上它也是{wy}一种有响环的物种。但是牛蛇和狐蛇同样在紧张时会快速震动它们的尾部。不管该不该因为响尾蛇在攻击前发出响声而把它称为蛇中君子，但这确实是个有趣的问题。

My respected editor:

   I am very glad that CCTV and your TV GUIDE invite us auditors to contribute articles on the subject” television and me”. I am very sorry to tell you that I am a disabled man. When you see my articles, you might think my handwriting is so bad. That’s because my hands can’t work, and I have used my mouth to do the writing for many years. These years I have written one essay after another and one poem after another.

   And now I am sending my essay to you with my most excited mood.

   Wish you well.

                                                       Yours Wang li
