平安夜啦，圣诞节啦，估计那几首耳熟能详的圣诞歌你已经听到吐了…… 不过你知道吗，这些歌曲其实也有不少科学填词版本！今年就带大家欣赏一首安静柔缓的…… 这首歌名叫“太阳光”（solar light），旋律大家肯定都非常熟悉了，就是那首“平安夜~圣善夜~” 经常循环出现在各大商场……只不过歌词改成了光线的内容，分成可见光、紫外光和红外光三段_(:з」∠)_
照例附上双语歌词，英文填词：Tariq Abdulla，演唱者：Natalie Windsor 中文词是我加的，写得不好大家见笑了——
Solar light, visible light 太阳光，可见光 Sensed by us, power of sight 瞧得见，开奖，视之源 Part of electromagnetic spectrum 它组成一段电磁波谱 Constant speed when inside a vacuum 真空里总保持一个速度 Scattered into the colours 散出五彩斑斓 Scattered into the colours 散出五彩斑斓 UV light, shortwave light 紫外光，短波光 Causes sunburn, when it's bright 晒太多，就受伤 Used for sterilization 照一照杀细菌消个毒 And forensics irradiation 侦查现场也用得上 Flowers reflect it for bees 引蜜蜂来帮忙 Flowers reflect it for bees 引蜜蜂来帮忙 Longwave light, infrared light 长波光，红外光 Hot objects, appear bright 越发热，它越强 Remote controls and night vision 用它做遥控器、夜视仪 Observe stars and their composition 分析恒星由什么组成 Snakes sense it to see prey 蛇靠它捉到晚餐 Snakes sense it to see prey 蛇靠它捉到晚餐
再重新介绍一下我们去年就魔性过一遍的《单细胞响叮当》吧。 虽然并没有时间做字幕，不过为了让大家更好地领略这首歌的魔性，我也临时给它进行了一个更加魔性的中文填词……（水平不行，一些地方可能意思不准确或者押韵押得太烂，大家领会精神就好，内容一切以原文为准_(:з」∠)_） 歌曲视频：
歌词： Single Cells (Jingle Bells) Early heterotrophs 早期异养菌 Fed on nucleotides 吃着核苷酸 As their rapid growth 它们长得快 Released carbon dioxide 把二氧化碳抛 But autotrophs would rule 食物渐渐少 As food grew less and less 自养菌来了 Generating their own fuel Through photosynthesis 它们会用光合作用，自己产燃料！ Oh, Single cells, single cells 哦~单细胞，单细胞 Bacteria and algae 细菌和小藻 Making up about a third Of world biomass today 生物量里三分之一都是它们造~ Hey Single cells, single cells 嘿，单细胞，单细胞 Thrive in every place 在哪儿都能长 Extremes of heat and pressure, 高温高压招呼上 They can live in outer space. 太空也走一场 The eukaryotic cells 真核细胞里 Are more complex inside 零件更是多 They have more organelles Especially nuclei 它有好多细胞器，还有细胞核 These organelles evolved As bacterial parasites 细胞器还有，细菌变来的 Were gobbled up by ancient cells, And began to thrive inside. 远古细胞吞了它，一起来生活~ Oh, Single cells, single cells 哦，单细胞，单细胞 Have lipid membranes 磷脂铺成膜 Eukaryotes have nuclei To store their DNA 真核生物DNA，核里做个窝 Hey Single cells, single cells 嘿，单细胞，单细胞 Some can flagellate 细菌有鞭毛 Amoebas walk with Pseudopods 阿米巴虫长伪足 And move by changing shape. 变形出个脚 Most species of yeast Are single celled funghi 多数酵母菌，atv，是单细胞真菌 On carbs and grain they feast 谷物交给它发酵 Making bread and wine 酿酒烤面包 In smaller buds they split 它们会出芽 Without a need to mate 不用成个家 But when food sources become scarce The yeasts will conjugate. 不过食物缺少时，也能啪啪啪~ Oh, Single cells, single cells 哦，单细胞，单细胞 Can cooperate 它们会合作 Bacteria form biofilms 细菌长成生物膜 Slime molds assimilate 黏菌聚成坨 Hey Single cells, single cells 单细胞，单细胞 Most self-replicate 自己来繁殖 But they have many other ways To transfer DNA. 要想交换DNA，办法还多得是！
不知道大家听完感想如何，反正我已经被成功洗脑了…… 圣诞限量款AI 谨代表果壳众AI，以上两首歌曲，祝圣诞夜也没人约的小朋友节日快乐！ 酷炫科学 ID：SciencePorn 灵魂译者窗窗的公众号 介绍各种“卧槽好棒”的科学小知识和科学趣图 (责任编辑：本港台直播) |
