我们对商务报告的写作原则和写作步骤都已经有了了解。而商务英语报告的写作语气也很重要。一般而言，报告大多由下属写给上司，使用的语言多为正式。此外，报告的内容和篇幅也决定了其写作语气比商务信函要正式得多。在撰写商务英语报告的过程中，可以适当多使用一些能提高语言正式度的英语语法结构。具体而言如下：
• 使用被动语态，如：The e-Source message will be delivered to the target audience multiple times through multiple avenues.
• 使用复杂词汇，如：The training system incorporates (includes) many visual aids.
• 使用长句子，如：The content and message of the kit will be similar to that sent to conventional outlets, but will be tailored to electronic media and will either be e-mailed to the Webmaster or sent in hard copy and on a diskette.
• 使用名词短语，如：The rectification of this problem can be achieved by insertion of a wedge.
• 使用非人物主语，如：Putting a copy of this CD-ROM in the hands of editors of targeted publications will allow them to see for themselves the features of the State Computer Store.
• 使用分词短语，如：Armed with this information, our customers will be able to identify trends and make strategic decisions in accordance with their agency’s goals.
• 使用动词不定式，如：To streamline the internal approval process, we can e-mail our quote to our purchasing agent for budget approval.
• 使用介词短语，如：With convenient access to Web Services in our online Electronic Product and Pricing Catalog & Order Tracking and Status System, customers can generate sales and service reports upon demand.
