英语作文辩证逻辑实例：为什么纽约是个“大苹果”？

　　【内容提示】

　　根据下面的内容提示写一篇因果分析型文章：

　　纽约城市旅客社（The New York City Visitor＇s Bureau）说， 50年前首先把纽约叫成大苹果的是爵士乐手和其他文娱表演人员。那时，他们每天转场到一个城镇。他们把每一个城镇称做树上的一颗苹果。一个演员不能在纽约获得成功，就不能看做是成功演员。这样，他们就把纽约叫做大苹果了。

　　Why New York Is Called the Big Apple

　　The New York City Visitor＇s Bureau says jazz musicians①and other entertainers② first called New York the Big Apple fifty years ago．

　　At that time jazz musicians earned money by performing in many cities and towns across the United States． They usually played their music in a different town each night． But the performers would like to play in New York City best of all． New York was the place with the best－paid jobs， the most money to earn， and a GREater number of people for jazz music． A performer was not considered successful until he was successful in New York． The early jazz musicians described each town and city in America as an apple on a tree． Naturally they called New York City the Big Apple． Later a night club was named The Big Apple， and a popular dance was also called The Big Apple． But no one except jazz musicians and some entertainers used this term to describe New York City．

　　About fifteen years ago， the city officials wanted to get more people to visit New York． They needed a new symbol for their city． They remembered the stories of the jazz musicians and began using the Big Apple in their advertisements． The idea worked．

　　Today so many persons from different parts of the world come and visit New York City every day． They may probably know New York＇s nickname③， though they may not know why the city is called the Big Apple．

　　【词语解释】

　　①jazz musician 爵士音乐乐师

　　②entertainer n．表演者

　　③nicknamen．绰号

　　【写法指要】

　　本文是说明纽约市的绰号大苹果的来历的。但是，从形式上看作者回答的是为什么的问题。如果我们把大苹果看做结果的话，给纽约起这个浑名的过程就是其原因。而原因只有一种，那就是爵士乐手和其他娱乐形式的表演者对纽约的描述。所以，我们把这篇文章说成是分析一因一果的说明文。
