Lesson 26 Picking Buttercups
第26課 摘毛茛
You all like to gather the yellow flowers called buttercups. The flowers are pretty, but there are other partsof the plant which you should look at. Let us dig up the whole plant with a big knife, and try to see all its parts, and learn what are their uses.
小朋友, 你們都喜歡摘一種叫做“毛茛”的小黃花。這些花兒很漂亮, 不過, 這種植物的其他部分, 你們也應(yīng)該看一看。咱們用一把大刀子挖出一棵來, 觀察一下所有的部分, 再了解一下這些部分都有什么用。
First, there are the roots, which are brown or white in colour. The roots fix the buttercup plant in the ground, and they also suck out of the soil a great deal of water every day. In this water there are many things taken from the soil which the plant needs for its food.
首先是“根”。根的顏色一般是棕色或者白色。根把毛茛固定在地上, 每天還從土壤里吸收很多水分。這些水分里, 有很多來自土壤的養(yǎng)分, 是植物需要的“食物”。
Then there is the green, branching stem. It holds up the leaves and the flowers, and spreads them out so that they can all get plenty of the fresh air and of the sunlight.
然后, 還有綠色的, 分出枝葉的“莖”。莖支撐著“葉”和“花”, 把它們分散開, 這樣, 葉和花就都能得到足夠的新鮮空氣和陽光。
The green leaves are covered with tiny holes, too small for our eyes to see. Through these holes the leaves draw in air, and they use part of this air as food. So the food of the buttercup is air and water, and a small part of the earth which is mixed with the water.
綠葉上面, 滿是細(xì)小的氣孔。這些氣孔小到我們的眼睛都看不見。葉子就通過這些氣孔來吸入空氣, 空氣里的一部分, 也是植物的“食物”。毛茛的“食物”就是空氣和水, 還有溶解在水里的一部分土壤。
