Consumers passionate about a product may create “earned” media by willingly promoting it to friends, and a company may leverage “owned” media by sending e-mail alerts about products and sales to customers registered with its Web site. (2011英语一text 3)
重点词汇：passionate, alert, register
解析： 本句为由“and”连接的两个并列举，“and”前半句句主语为“consumers”，谓语为“may create”，宾语为“earned media”，“and”后半句主语为“a company”，谓语为“may leverage”，宾语为“owned media”。
翻译: 对产品充满热情的消费者可能会通过自愿向朋友推销来创建“口碑”媒体，而公司可能会通过向在其网站注册的客户发送有关产品和销售的电子邮件提醒来利用“自”媒体。
