考研英語寫作投訴信又可稱為抱怨信，其主要目的是表達寫信人對于某一情況的不滿。人們在生活中經(jīng)常會遇到一些不愉快的事情，比如消費利益受損、正常生活和工作受到干擾等等，有時寫封投訴信不失為一個解決辦法。那么，投訴信應(yīng)該怎么寫呢？

投訴信通常包括以下幾個方面的內(nèi)容：說明投訴的原因并表示遺憾；實事求是地闡述問題發(fā)生的經(jīng)過，切忌夸大其詞；指出問題引起的后果；提出批評及處理意見，或敦促對方采取措施，或提出所希望的賠償以及補救方式。

投訴信的寫作策略：說明投訴問題——描述具體情況——期待解決方案。

注意事項：寫投訴信時語氣要冷靜、鄭重、克制，不必過于禮貌。但也要就事論事，不能進行人身攻擊。同時，在描述問題時盡量采用被動句式，使描述更加客觀合理。
