……我一直在研究煤焦油里的化学基团和取代物，也有了不少科学发现，但据我所知，都没有什么商业价值。一天晚上，我做实验做得太起劲儿，很晚了才急匆匆地去吃晚饭，而且还没洗手。我坐下掰了一块面包塞进嘴里，感觉甜得难以言喻。我也没多想，以为是沾了蛋糕或者果脯。我去漱了漱口，用手巾擦嘴，可这手巾竟然比面包还甜。这下我就不理解了。我又往杯子里灌水，冲洗我嘴上被我的手指碰过的地方。那水就像糖浆一般甜。我突然想到，前前后后这所有甜味都是我引起的，于是我舔了舔大拇指尖，果然是甜过这世上所有的甜品。我立马就懂了，我从煤焦油里发现或发明了一种超越任何糖的糖类。我也不吃晚饭了，一溜烟跑回实验室，兴奋地把烧杯和蒸发皿都尝了一个遍。万幸里面没有任何腐蚀性或有毒的液体。
