      章節正文

      使用逗號分隔枚舉中的項目。

      Example: Old McDonald had a pig, a dog, a cow, a horse.

      “and”之前的逗號是可選的。

      Example:
       Old McDonald had a pig, a dog, a cow and a horse.
       Old McDonald had a pig, a dog, a cow, and a horse.

      如果兩個項目是同一個unit,請不要在“and”之前使用逗號 (Ham and eggs as a dish is a unit and should therefore not be separated by a comma.)

      Example:
       Old McDonald had soup, ham and eggs and apple pie for dinner.
       Old McDonald had soup, ham and eggs, and apple pie for dinner.

      如果枚舉中的所有項都以and, or, nor分隔,請不要使用逗號 

      Example:
       Old McDonald had a pig and a dog and a cow and a horse.
       Old McDonald had a pig or a dog or a cow or a horse.
       Old McDonald neither had a pig nor a dog nor a cow nor a horse.


      生詞表:
    4. therefore [´ee?f?:] 移動到這兒單詞發聲  ad.&conj.因此;所以   (初中英語單詞)
