阅读理解。 All over the planet, they are disappearing. Scientists are worried. It may mean the end of the world. I'm not talking about disappearing frogs. I'm talking about absent vowels (元音). I got a message the other day that said,' Mt@ 3rd st crnr@ 12', signed (签字) 'BT'. What did it mean? A young man in the office told me that BT meant' beauty' and translated:' A beautiful young woman wants to meet you at the corner of Third Street at noon.' The following week I was at a private dining club when a Hong Kong banker named David told me he had met with a man who pronounced his name Choong,but spelt C - H - N - G.' There can't be many names with no vowels in them,' he said. It turned out he was sitting next to a Singaporean doctor named Ng. Vowels are disappearing at high speed among businesses, too. Ever wondered what happened to Reebok, the sportswear company? It's still around but has renamed itself Rbk. Kentucky Fried Chicken became KFC. I've read articles saying that the no-vowels trend (趋向) is caused by companies trying to give their products the shorthand spelling liked by young people. But a research finds that the real reason is often more uninteresting. Flickr,one of the busiest websites on the Internet, was set up by people who wanted the name Flicker but were too careless to register (注册) that word. Have any readers ever been to a small town in the mountains of California called Zzyzx? A man named Curtis Howe Springer founded it as a health club and called it Zzyzx because he thought it sounded different. The business failed. People who looked through lists for somewhere to go never reached it. Older readers may remember the computer game Zzyzzyzz that appeared in 1982. Fans did not know how to ask for it. James Gleick's book Faster has been re-titled FSTR. But the revision is half-hearted with the main text of the book still having vowels. Why not write the whole book in the simpler way? U cn stll rd the wtht vwls. On the other hand,just know that vowel-free words can be explained in different ways. One day I'll get a message from a BT  who may be a beauty. But I'm afraid a bat (蝙蝠) will be out there. 1. The writer's purpose in the passage is _______.
