monosodium gluetamate （味精）

Biologist studies frogs

A noted biologist, who had been studying little green frogs in a swamp, was stumped. The frog population, despite efforts at predator control, was declining at an alarming rate. A chemist at a nearby college came up with a solution: The frogs, due to a chemical change in the swamp water, simply couldn't stay coupled long enough to reproduce successfully. The chemist then brewed up a new adhesive to assist the frogs' togetherness, which included one part sodium. It seems the little green frogs needed some monosodium glue to mate.

為不懂英文的朋友翻譯一下：

生物學家 發現河塘的青蛙 急劇減少。用什麽措施都無效。

附近的一個化學家發現原來是因為水中化學成分的改變，是青蛙交配時，配在一起的時間不夠長。

於是他配出一種含鈉的膠，使青蛙交配時彼此粘在一起，以延長交配時間。看來青蛙是需要一種：

單鈉（monosodium)的膠(glue) 來（to）交配（mate）

英文的發音即為：
monosodium glutamate （味精）
