address与speech address和speech都是指“演讲，演说”，细微区别如下。 address是名词意思是“演讲，演说”，它主要仔细准备的正式演说，经常用在隆重场合，比如，就职典礼或者是重要集会上，而且它还强调听众在场这个事实。比如： He had scheduled an address to the American people for the evening of May 27.他已经安排在5月27日晚向美国人民作一个演讲。Tonight's televised presidential address is at seven.今晚总统的电视演讲时间是七点。 They heckled him and interrupted his address with angry questions.他们对他起哄，以愤怒的诘问打断他的演说。 speech意思也是“演讲，演说”，它是一个普通用词，不管发言长短，有没有准备都可以统称为speech。它可以表达思想感情、传达通告等等。比如： He made the announcement in a speech on television.他在一次电视讲话中发表了这一声明。Several people made speeches at the wedding.有几个人在婚礼上讲了话。 She is due to make a speech on the economy next week.她将在下周作有关经济的演说。He delivered his speech in French.他用法语作的演讲。
