英国学生科学读本 Lesson 9 种子(1)
第九课 种子(1)
Can you tell me the names of some seeds? You all know the acorn, which is the seed of the oak. I am sure you have also seen peas, beans, Indian corn, wheat, and many other seeds. ACORNS(橡子)
小朋友, 你能告诉我, 这些种子都叫什么名字吗? 大家都知道橡子, 橡子是橡树的种子。大家也一定见过豌豆、大豆、玉米、小麦的种子, 还见过好多好多别的种子。
Apples and pears are nothing but seeds covered with a thick coat. The little brown seeds are packed snugly in the core at the centre of the apple, and all round about them there is a thick white covering which is sweet and juicy and good to eat. APPLE CUT ACROSS (横切的苹果)
苹果和梨, 都是包着“外衣”的种子。小小的褐色种子, 紧紧地挤在苹果的中间, 周围是一层厚厚的白色外衣, 味道又甜, 汁水又多, 可好吃了。
All seeds that have this sort of covering are called fruit. This is the kind of seed that boys and girls like best. They are all fond of a fine ripe apple or a juicy pear. They would like to pull fruit off the trees in the orchards all day long. INDIAN CORN (玉米)
有这种外衣的种子, 就叫“果实”。这就是小朋友们最喜欢吃的!他们都喜欢熟透的苹果, 喜欢多汁的鸭梨。他们在果园里摘水果, 一摘就是一整天呢!
Let us soak some beans for an hour in hot water, and then see what they look like. Strip off the brown skin, and you will see two thick white pieces inside.
咱们把大豆泡在热水里, 泡上一个小时, 看看是什么样子? 把褐色的皮剥下来, 就能看见种子里面有两瓣厚厚的白色东西。
These are really two very thick leaves called seed-leaves. Between the edges of the seed-leaves you will find a tiny plant.
这两个东西, 其实是两片非常厚的叶子, 叫“子叶”。两片子叶的边缘中间, 你会看见一棵特别小的草。
In this little plant, if you have good eyes, you can see a small bud, which will one day grow up and form the stem of the young plant. You may also see a very little pointed thing, which will grow down and form the root. SEED-LEAVES OF BEAN (大豆的子叶)
要是你眼神足够好, 在这棵小草里面, 你会看到一个小芽, 这小芽以后会长大, 变成一颗幼苗的茎。你还可能看到一个非常小的尖儿, 这个尖儿以后会往下长, 长成幼苗的根。
Thus we see that a bean-seed is a perfect little plant, having leaves, and a stem, and a root. In the next lesson, we shall learn how the tall, strong plant grows from a single seed.
你瞧, 大豆的种子, 自己也是一棵小草, 有叶子, 有茎, 有根!下一课, 我们会学到, 一颗小小的种子, 是怎么长成那些高大的树和草的。
