为什么把纽约叫做“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（Th Nw York City Visitor＇s Burau）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。

【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。
