const TrollingArticle = ['巨大的灰色乌云笼罩在灰色的、各式各样的建筑之上，炫目的LED灯管被竖直放置于C市的各个角落。深灰的马路上粉刷着浅灰的虚线和实线，引导着川流不息、来来往往的车辆与人群。\n\
C市的一天，便这样开始了。',
'2050年，地球环境进一步恶化，人类生存资源濒临枯竭，即使科技再高速发展也无济于事。但此时，人类的基因已经完全破译，每个区段每一对碱基对控制着什么形状早已能够被识别、控制与修改。为了维护社会秩序，掌管C市的P党在该技术萌芽时便花重金将专利从相关公司手中买下，垄断了这一技术。所以，这达成了P党内部核心人员一个心照不宣的秘密。',
'15年前。巨大的双链DNA模型在房间内投影出来，右旋的优美轮廓让在场的所有科学家都赞叹不已。喧哗声中，一个人走上演讲台，调试好麦克风，开始了它的发言。\n\
“大家好。正如大家所知，人的眼睛是根据所看见光的波长来识别颜色的，而可见光谱中的大部分颜色可以由三种基本色光红、绿、蓝按不同比例混合而成，形成了连续的可视光谱。人类肉眼能区分其中的几百万至一千万种。经过十余年的研究，我们发现人类基因中关于色彩识别的区段较为冗长；为降低生活成本，我代表P党在此宣布自今年1月1日00:00起将C市所有居民基因中的色彩识别区段删除，仅保留黑白两种基本色光。同时，相关政策也将陆续实施，感谢各位的理解与支持。”\n\
……',
'2034年12月31日，23:58。此时，C市的广大人民群众还不知道他们即将面临什么，有的已早早入睡，有的还在五彩斑斓的繁华都市中享受着绚烂多彩的生活。市中心高楼上的始终嘀嗒，分针逐渐指向了12的正下方。\n\
00:00。\n\
所有还醒着的人们的记忆模块被完全刷新。\n\
“这是一个非黑即白的世界。”\n\
“灰色由不同比例的黑白色组成，是最常见的一种颜色。”\n\
“自古以来便是这样。”\n\
所以，这场历史性的革命在悄无声息中圆满完成了。没有骚动，没有恐慌。',
'与此同时，电子课本、电子词典被同步刷新。颜料标签被迅速替换。文字与影像资料被大幅度删改，相关学科被取消。红、黄、绿灯依次换为圆形、方形、三角形灯。颜色引导标识改为黑白点线面组合引导标识。\n\
……\n\
一切的一切，归零。\n\
生活照常。',
'2030年，C市成为E国少数几个未通过《全可视区段色彩使用法案》的国家。P党声称此法案与C市传统颜色阶级制度价值观不符，不利于人口增长，可能引发社会混乱。此前，C市已出现多次因争取全区段可视色彩使用权而导致舆论风波的现象，重重封锁也无济于事。同时，其声称外部势力也在对C市青少年以各种潜移默化的方式渗透色彩多元化共存理论，造成了巨大影响。为了彻底解决这一问题，P党最后做出了取消色彩可视化这一决定，才有了这场看似荒谬的颜色革命。',
'雨后，晴空。天边罕见地出现了一道彩虹，只是再也无法被C市的孩子们看见了。但他们还从课本上了解过这一自然景观，它被称为“灰虹”，天空中呈现了七种不同深浅的黑白色条带，蔚为壮观。\n\
小朋友们发出天真无邪的笑声，在浅灰的草坪上和父母一起欣赏美丽的灰虹。\n\
风也轻轻。\n\
……',
'但那无法被看见色彩的彩虹，它还存在着啊。幸好，C市的科学还没有发展到能将彩虹粉刷为黑白的地步，幸好，它改变的只是我们人类本身。不论你是否承认彩虹的赤橙黄绿青蓝紫，它都存在着，从古至今。只是对C市的人来说，看不见了罢。\n\
带着无色的双眼去看待这个世界，世界当然是没有颜色的啊。',
'或许会问，为什么那些所谓的“外部势力”没有到C市来宣传呢？\n\
因为C市早已故步自封了呢。C市早已在城郊筑好了高墙，外部势力很难进入，内部民众也难以出去。大家的梯子都被没收了，那可是违法的啊。\n\
从前，颜色是有阶级限制的，P党内部核心人员身穿黄色，大官穿紫色，小吏穿青绿色，平民穿灰白色。倘若僭越，是要遭来杀身之祸的。现在可好，民主、自由、平等，大家都一样，没人管你穿什么颜色，只是深深浅浅罢了。果然，社会进步，百姓安康。',
'深夜，高楼。P党那位发表演讲的科学家站在窗边，望着依旧五光十色的建筑，冷笑一声，又走进无边的黑暗。\n\
……\n\
“又经过几年的研究，我们发现人类基因中关于色彩识别的区段没有其存在的必要性。为进一步降低生活生产成本，我代表P党在此宣布自今年1月1日00:00起将C市所有居民基因中色彩识别区段全部删除。同时，相关政策也将陆续实施。”“感谢各位的理解与支持。”',
'00:00。\n\
C市的人全都瞎了。\n\
