Digital services include everything from providing a platform for selling goods and services online to targeting advertising based on user data, and the tax applies to gross revenue from such services.

　　重点词汇：digital, platform, revenue

　　重点短语：base on, apply to

　　解析：

　　该句中，“Digital services”为主语，“include”为谓语，“everything”为宾语，“from providing a platform for selling goods and services online to targeting advertising based on user data”为介词短语做后置定语，修饰先行词“everything”。后接一个由“and”连接的并列句，该并列句的主语为“the tax”，谓语微“applies to”，宾语为“gross revenue”，“from such services”为介词短语，修饰“gross revenue”。

　　翻译：

　　数字服务包括从提供在线销售商品和服务的平台到基于用户数据的有针对性的广告，以及使用此类服务总收入的税务。
