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，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，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……
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！
