1879年，一条科技新成果的消息传到英国后，伦敦证券交易所的煤气股票价格狂跌。该

《联邦宪法(1787年)》

When I was young, I wanted to be a model, so when a national competition was nearby, I asked my parents to take me for an audition(试演) and they agreed, I was selected and told I had potential. They said that for only $900 I could attend a weekend event that a number of the most famous modeling agenies(中介) from around the world would attend. At 13, my hopes of fame and fortune(名利) clouded my judgment and I begged my parents to let me go. We have never been rich, but they saw my enthusiasm and at last they agreed.

I imagined being signed by some famous model companies. For .months, any boredom or disappointment that I faced disappeared because I knew I would soon have the chance to be a real model. I thought I would appear in the covers of famous magazines!

Of course, I wasn't signed, but what hurt the most was being told that if I grew to 5'9' (about 1.75 meters) I could be a success. I sprayed for a growth spurt(冲刺) because I could not imagine giving up my dream. I met with a local modeling agency and the agent required $500 for classes, $500 for a photo shoot(拍摄), and $300 for other fees. My parents only agreed after hours and hours of my begging.

The agency sent me out on a few auditions but with every day I did not receive a call, I grew more disappointed. The final chance came in July after I had decided to focus on commercial modeling. There was an open call(公开挑it) in New York City. We spent hours driving and spent another few hours waiting, only to be told that I was too short, I could hardly stand it.

Years later, I realize that the trip to New York was good as it made me notice I didn't actually love modeling, just the idea of it.1 wanted to be special and I naively(天真地)decided to reach an impossible goal. The experience has made me stronger and that will help me in the future.
