9. Carrots help you see in the dark. 胡萝卜有助于提高夜视能力

This was part of World War II propaganda. The British had invented radar and we began bombing the Germans at night. The Germans, confused as to how we bombed them at night, started researching how we were doing it. The British government began to spread the rumor that it was the carrots in our ration packs that helped us see in the dark (Note: "in order" is rarely needed) to put the Germans off our trail. They figured it out eventually, but by that time, the rumor had already stuck.

这是二战期间的一个宣传。英国人发明了雷达并开始在夜晚轰炸德国。德国人就对英国人是如何在夜晚进行轰炸作业感到很好奇，并开始研究英国人是如何做到夜间瞄准的。英国政府就散布谣言说他们食用一定数量的胡萝卜来提高夜视能力来迷惑德国人。德国人最后发现了这只是个谣言，但到那时是这一说法已经被广泛接受了。
