9. Carrots help you see in the dark. 胡蘿卜有助于提高夜視能力

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.

這是二戰(zhàn)期間的一個(gè)宣傳。英國人發(fā)明了雷達(dá)并開始在夜晚轟炸德國。德國人就對英國人是如何在夜晚進(jìn)行轟炸作業(yè)感到很好奇，并開始研究英國人是如何做到夜間瞄準(zhǔn)的。英國政府就散布謠言說他們食用一定數(shù)量的胡蘿卜來提高夜視能力來迷惑德國人。德國人最后發(fā)現(xiàn)了這只是個(gè)謠言，但到那時(shí)是這一說法已經(jīng)被廣泛接受了。
