杂谈
It seems to be the fate of relatively new art forms to suffer from an excess of names. Very short fiction pieces have been called “short shorts," "micro-fictions," and "instant fictions".
似乎每每出现一个相对较新的文学形式，都免不了要经历很多名称的变化。非常短的小说片段曾被称为”短篇“、微小说”和“速读小说”。
The short nonfiction genre has been going through a similar identity crisis for the past few years. It has been called "concise literary nonfiction," "compressed nonfiction," the "micro-essay," and the "mini-memoir." However, just as "flash fiction" seems to be emerging as the preferred moniker for very short stories, "flash nonfiction" is currently the most common name given to very short essays.
短篇非小说类文学作品体裁在过去几年也经历过相似的身份危机。它曾被称为“简洁非小说类文学作品”、“精华非小说类文学作品”、“微短文”以及“迷你回忆录”。但是，正如“flash fiction”成为超短小说最合适的名称，“flash nonfiction”是目前最适合非常短的文章的称谓。
It should be clarified that very short fiction and nonfiction are not "new" art forms by any means — both are easily a few thousand years old. What's relatively new is treating these types of writing as separate literary genres, hence the need for new names.
必须说明一点，超短篇小说和非小说类文学作品绝不是“新”的艺术形式，它们都有几千年的历史。相对比较新颖的只是将这些写作类型当做独立的文学体裁来对待，因而也就需要为它们取一个新名字了。
