Lesson 57 Sulphur
第57課 硫
Did you ever have to take a mixture of brimstone and treacle? This mixture has not a pleasant taste, but it is a useful medicine; and if it will do us good, we should not care much whether it has a nice taste or not.
小朋友，你們有沒有過這樣的經歷，必須喝下一種“硫磺和糖蜜”的混合物？這種混合物的味道并不太好，但它是一種有用的藥物，對身體有好處，所以我們也就不用在意好不好喝了。
Sulphur is the proper name of the yellow powder called brimstone. Sulphur is an element; that is, it is made of one kind of matter only. Out of a piece of sulphur no one can get anything but sulphur.
有一種黃色粉末，傳統上叫做“硫磺”，它的正式名稱叫“硫”。硫是一種“元素”，也就是說，它只是一種物質構成的。從一塊硫里，人們只能得到硫，得不到別的東西。
You can buy sulphur at the chemist's in three forms. First, there is milk of sulphur, which is a very fine powder; next, there is flowers of sulphur, which is a rather coarse powder; and lastly, there is roll sulphur, which is sold in solid sticks.
你可以在化學品商店里買到三種樣子的硫：第一種是極細的粉末，名叫“硫磺乳”；第二種是相當粗的粉末，名叫“硫華”；第三種是“硫棒”，是以固態棒狀的形式出售的。
Sulphur is of a bright yellow colour. A piece of roll sulphur snaps easily when we try to bend it, so that we say it is brittle. It has neither taste nor smell when cold, but when warm it has a slight smell.
硫的顏色是淺黃色。要是想把一根硫棒折彎，它很容易就會折斷，所以硫棒很“脆”。硫在低溫下沒有氣味也沒有味道，但在溫暖的地方會有微弱的氣味。
Some people put a stick of sulphur in the dish from which their dogs drink; but this is of no use as a medicine, for it will not dissolve in water.
有些人會在狗狗喝水的盤子里放一根硫棒；但不是做藥用，因為它不會在水中不會溶解。
Sulphur is a rather light solid, but it does not float in water. It burns very easily, and with a pale blue flame. As it burns it produces a gas with a nasty smell.
硫是一種很輕的固體，但并不能浮在水面上。硫很容易就能燃燒，燃燒的時候，會發出淺藍色的火焰，還會散發出一種難聞的氣體。
