Lesson 40 The Sugar-Cane

第40課甘蔗

Have you "a sweet tooth"? Do you like things with sugar in them? If you do (and I am almost sure that you do),you will like this lesson, for it will tell you where sugar comes from, and all about it.

小朋友，你愛(ài)吃甜食嗎?你喜歡加糖的東西嗎?要是你喜歡(我差不多肯定你會(huì)喜歡)，你也會(huì)喜歡這一課，因?yàn)檫@一課告訴你的，正是糖的來(lái)源，以及關(guān)于糖的一切!

Sugar is found in the juice or sap of many plants. You cannot see the sugar, because it is dissolved in the water of the juice. Sugar dissolves so well that one pound of water can dissolve three pounds of sugar.

很多植物的汁液，或者樹(shù)汁，里面都有糖。但是這種糖是看不見(jiàn)的，因?yàn)樗芙庠谥旱乃掷锩媪恕Ｌ堑目扇苄苑浅：?，一磅水能溶解三磅糖?

The sweetness of most fruits is caused by a kind of sugar called grape-sugar. You know that grapes taste sweet. Now raisins are just dried grapes; and if you cut open some raisins, you will be sure to find inside them many little hard grains of this grape-sugar.

多數(shù)水果的甜味，來(lái)自一種叫做“葡萄糖”的糖。你知道葡萄吃起來(lái)是甜的。曬干了的葡萄叫葡萄干;把葡萄干切開(kāi)，就肯定能在里面，找到很多這種葡萄糖粒。

But the sugar which we use to sweeten our tea, and which is sold in all the grocers’shops as "lump-sugar" or "brown sugar," is made either from the juice of the plant called the sugar-cane, or from that of another plantcalled the beet.

不過(guò)，我們放在茶里的糖，在所有雜貨店里賣的糖，叫做“方糖”或者“紅糖”，這種糖要么是一種叫“甘蔗”的植物的汁制造的，要么是另一種叫“甜菜”的植物制造的。

The sugar-cane grows in very hot countries. It is a tall kind of grass, about twice the height of a man. Its smooth, shining stems are about two inches thick, and they have knots or joints at every five or six inches.

甘蔗生長(zhǎng)在非常炎熱的地區(qū)，是一種長(zhǎng)得很高的草，差不多有成年人高度的兩倍。甘蔗的莖很光滑，有光澤，直徑大概有兩英寸;每5-6英寸就分一個(gè)“節(jié)”。
