在外贸函电中，要注意保持交际双方地位的平等，即交易双方的谈判应尽量建立在平等互利的基础上，为表示礼貌而过分谦卑的言辞会适得其反，令对方对你的能力产生怀疑，如: could rest assured that we would make every effort to effect the shipment as soon as possible so as to meet your demand. (贵方可以放心，我们也向贵方确保，我们会竭尽全力地使发货尽可能地满足贵方的要求。) 2. We assure you that we shall do our best to expedite shipment. (我们向贵方确保，我们会加速发货。) 从上面两句话，我们可以看出，例1显得太过自贬，而2就显得更为得体。 xxx
