商务
英语写作中，正确地使用语法、拼写和标点符号是非常重要的。但是除了遣词造句外，更重要的是根据接受信息的对象来选择恰当的文字表达方式和语气，要从收件人的角度设想他们将会接受什么样的行文语气，更要考虑到收件人的需要、愿望、兴趣和问题等，这样才能确定的应对方法或方式，达到交流的目的。
所以，要想确保
沟通的顺畅、达到交流的目的，必须使用恰当的语气。文书中的语气反映着对整个商务事件的关注程度、对于开展合作的诚意及对工作认真负责的态度。无论是开展业务、投标项目，还是在催要欠款、投诉的文书写作中，都要本着解决问题的原则，有力有礼有节地采用合适的语气，既不能盛气凌人、缺乏灵活，也不能恶语相伤、刻薄无理。
不同的语气表达出不同的信息，既可以是咄咄逼人，也可以是彬彬有礼。不恰当的语气会导致交流的不快和失败，甚至是事与愿违。所以，根据实际交流的需要来选择和把握好语气的使用至关重要。
好消息或正面消息可直截了当地点明主题，但传递坏消息或负面消息时，则一定要语气委婉，尽量避免开门见山直接表明。试比较以下两个例子。

所以，即使是在传递一个负面的信息，也要避免使用消极词语，诸如“We don't”, " Irefuse".“You cannot”, "Your loss is”,“It is impossible that…”、“I am not prepared to”这样的词语。应尽量站在正面的立场上并以积极的、委婉的、乐观的、更具建设性的方式来传递信息，即比较好用委婉(Indirect Order)的语气来表达，也可以通过表示愿意提供帮助来弱化坏消息带来的消极影响。例如，可以这样来表达:
If you need any further information, please do not hesitate to contact me.
If there is anything I can do for you, please do not hesitate to let me know.
为了交流合作的顺利进行，即使责任不在本人，也切忌指责对方。因此，以下表达法在商务写作中要尽量避免使用:
You failed to…
We must insist…
