基本释义
[adjective] occurring at irregular intervals or only in a few places; scattered or isolated
[形容词] 以不规则的间隔或仅在少数地方发生；分散的或孤立的
深入解读
Sporadic 一词源自希腊语 spora （种子、播种），与英语单词 spore （孢子）同源。
自然条件下植物的种子随风传播（如蒲公英）或附着经过的动物传播（如苍耳），其生长出来的后代必然东零西落、四处分散。所以 sporadic 其本义即指“（植物等）分散的、非集中于一处的”，比如：
- 分散在各地的种种植物
sporadic genera of plants
当用在医学领域时，则表示“（疾病）偶发的、非流行性的”，比如：
- 一种偶发病
a sporadic disease
说到这里，不妨复习一下小站曾在 小词详解 | pandemic 中提到的3个有关流行病的术语：
- pandemic
全国性或全球性的大流行病 - epidemic
流行病 - endemic
地方性流行病
Sporadic 从上述含义再进一步引申用语形容普通事物时，则表示“（事例等）孤立的、个别的”或“偶尔发生的、零星的、间或出现的、阵发性的”，比如：
- 仍能听见零星的枪声。
The sound of sporadic shooting could still be heard. - 候选人的演说为零零落落的掌声所打断。
The candidate’s speech was interrupted by sporadic applause.
名人用例

始终如一坚持做的小事，即使平淡无奇，也会比零星做的大事收获更多。
