今天，我们要学的词是ball。
音标： [bɔ:l]
释义：是球的意思。不过，ball 作为名词，在英语里还有一个常用的意思，指正式舞会。
例句：
"After being sworn in as the first-ever African American president, Barack Obama and his wife Michele are scheduled to attend ten inaugural balls on January 20th,"
1月20号宣誓就职成为美国有史以来的第一位非洲裔总统后，奥巴马计划协同夫人米歇尔出席十场就职舞会。大家都很关心米歇尔的服饰打扮。
"The dress the first lady wears to the official balls will become part of history,"
因为第一夫人参加就职正式舞会时穿的晚礼服将成为历史的一部分。
