死亡是人們避諱談論的主題，因此在直接敘述的詞彙之外，出現了大量的委婉表達方式。過去關於委婉語的研究以第一語言角度切入爲大宗，著重於功能目的、構造方式、類型方析以及英漢對比方面。隨著學習中文的人數成長，中高級華語學習者日益增加，當他們在瀏覽報章雜誌等真實語料時，一定會接觸到死亡相關事件，因此，能夠掌握死亡相關詞彙對於華語學習者的閲讀理解力有其重要性，然而一般委婉語辭書及研究中所收錄的詞彙數量雖多，但不少詞彙的詞頻極低，甚至連母語者也很陌生，若未透過有效篩選，學習者的學習成效將事倍功半，然而目前由二語學習角度出發的委婉語教學研究卻極爲匱乏。爲了解決華語學習者在實際生活中閲讀真實材料的需求，提高他們在委婉語相關詞彙的掌握度，本研究擬探討之研究問題爲：以閲讀真實材料的需求爲出發點，透過語料庫篩選出日常文本及新聞標題中相對高頻之死亡相關用詞，再對照教材及詞表提出教材編寫建議，並透過隱喻與轉喻理論整理相對高頻死亡相關詞彙，透過教學引導提高學生相關詞彙理解猜測力，最後根據詞頻與詞彙難易度，提出一套死亡主題相關詞彙的教學順序原則及實踐建議。

Death is a taboo in all cultures. People tend to resort to a wide variety of euphemisms when touching upon this topic. Most of the researches in the field of Chinese as a Second Language (CSL) investigated euphemisms from the perspective of first language learning and teaching, focusing on their functions, compositions and underpinning concepts, while some researchers looked into the similarities and differences of English and Chinese expressions. Recently, with a steady growth in the number of CSL learners, more and more higher-intermediate and advanced learners encounter death-related euphemisms while reading the authentic materials. However, learners find it laborious to figure out the true meaning and usage of these expressions. A great many expressions are listed in the dictionaries and related research reports though, most of them are rarely used in real-life communication. What's more challenging to the learners is that the expressions are neither arranged systematically in the dictionaries and reference books, nor are they explained from the perspective of a second language learner. A better presentation and explanation of these terms to facilitate effective learning is obviously a must. To meet the advanced CSL learners ' need in comprehending authentic materials and help them master the death-related euphemisms, we have summarized in a list the expressions, sequencing from the perspective of pedagogical needs in accordance with their frequency in authentic materials and the metaphor- and metonymy- related theories. In preparing the list, we sifted through the corpora, identifying the most-frequently-used expressions in authentic materials and news headlines. Having compared with the existing teaching materials, we short-listed the expressions that are most needed in advanced teaching materials. The expressions were then arranged based on the metaphor- and metonymy-related theories, aiming to guide learners to recognize and understand these taboo expressions effectively.
