Bioluminescence in Marine Life

Bioluminescence is the emission of light by living organisms, a phenomenon seen in many marine species and some land species, such as fireflies. This natural light production results from a chemical reaction involving luciferase and luciferins, the energy molecule ATP, and oxygen. The essential light-emitting components--the luciferins and luciferases- are specific for different organisms, and the color of the light produced might also vary, with blue-green being common in oceanic organisms.





Marine organisms use bioluminescence for various purposes, including attracting prey, deterring predators, and communicating. For example, certain species of jellyfish emit light when threatened, creating dazzling display to confuse predators. Deep-sea fish utilize bioluminescence to lure prey. In the same way moths are attracted to light, many sea organisms are attracted to bioluminescent glows and thus end up within reach of a hungry predator.





Researchers are fascinated by bioluminescence for its potential applications. The study of bioluminescent organisms has led to advances in medical imaging.Researchers can use luciferin to highlight diseased human cells and determine how effectively a drug has worked against them. Scientists are also exploring how bioluminescent proteins can be used to track the movement of cells within the human body.

"1. 题干:文中 “deterring” 一词的意思最接近以下哪一项?(原文:The word ""deterring"" in the passage is closest in meaning to) 2. 分析 题目类型:词汇题 解题策略:此类题需结合单词所在的上下文(尤其是前后搭配、举例),推断单词的含义,再匹配选项。 3. 定位信息理解 原文定位:“Marine organisms use bioluminescence for various purposes, including attracting prey, deterring predators, and communicating. For example, certain species of jellyfish emit light when threatened, creating dazzling display to confuse predators.” 信息理解:“deterring predators” 是海洋生物用生物发光的目的之一,后文举例 “水母遇威胁发光迷惑捕食者”,可推断 “deterring” 是 “阻止、使… 不敢靠近” 的意思。 4. 分析选项 (A) discouraging(阻止、使打消念头) 分析:与 “deterring”(阻止捕食者靠近)的含义一致,此为正确答案。 (B) alerting(提醒、使警觉) 分析:与 “迷惑 / 阻止捕食者” 的逻辑不符,排除。 (C) threatening(威胁) 分析:文中是 “阻止捕食者”,并非 “威胁捕食者”,排除。 (D) fleeing from(逃离) 分析:“deterring” 的主体是海洋生物,动作对象是捕食者,并非 “海洋生物逃离”,排除。"
