性别意识作为自我意识的重要内容之一和健全人格形成的重要要素，是指人对自己所属社会性别的认同。传统性别意识观念将性别割裂地分为两类——男性和女性，二者处于二元对立的状态之下，且男性往往被认为优于女性。在这一前提以及在阿加莎·克里斯蒂所处的女权运动蓬勃发展这一特殊时代背景的综合影响下，对其性别意识观的分析是具有意义的。《无人生还》作为克里斯蒂的代表作之一，国内外对其的研究不胜枚举，而对于其中所体现的性别意识观念的分析则屈指可数。因此，本文旨在通过对小说中人物性格、行为、心理等的具体分析来总结出小说中对传统性别意识的突破和固守，并借助弗吉尼亚·伍尔夫的“双性”概念做出解释，进而对阿加莎·克里斯蒂本人的性别意识观进行提炼。

Gender awareness, as one of the important elements of self-consciousness and the formation of a sound personality, refers to a person's identification with his or her own social gender. The traditional gender consciousness divides the sexes into two separate categories, men and women, which are in a state of dichotomy, and men are often regarded as superior to women. Under the combined influence of this premise and the particular context of the burgeoning feminist movement in which Agatha Christie lived, it is meaningful to analyse her view of gender consciousness. As one of Christie's masterpieces, And Then There Were None has been the subject of numerous studies, but there are few analysing the gender consciousness embodied in it. Therefore, this thesis aims to summarise the novel’s breakthrough and clinging of traditional gender consciousness through the specific analysis of characters’ personalities, behaviour, and psychology, and to explain it with the help of Virginia Woolf’s concept of “androgyny”, so as to refine Agatha Christie’s own concept of gender consciousness.
