英國學(xué)生科學(xué)讀本 Lesson 9 種子(1)
第九課 種子(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, 你能告訴我, 這些種子都叫什么名字嗎? 大家都知道橡子, 橡子是橡樹的種子。大家也一定見過豌豆、大豆、玉米、小麥的種子, 還見過好多好多別的種子。
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 (橫切的蘋果)
蘋果和梨, 都是包著“外衣”的種子。小小的褐色種子, 緊緊地?cái)D在蘋果的中間, 周圍是一層厚厚的白色外衣, 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)
有這種外衣的種子, 就叫“果實(shí)”。這就是小朋友們最喜歡吃的!他們都喜歡熟透的蘋果, 喜歡多汁的鴨梨。他們?cè)诠麍@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.
咱們把大豆泡在熱水里, 泡上一個(gè)小時(shí), 看看是什么樣子? 把褐色的皮剝下來, 就能看見種子里面有兩瓣厚厚的白色東西。
These are really two very thick leaves called seed-leaves. Between the edges of the seed-leaves you will find a tiny plant.
這兩個(gè)東西, 其實(shí)是兩片非常厚的葉子, 叫“子葉”。兩片子葉的邊緣中間, 你會(huì)看見一棵特別小的草。
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 (大豆的子葉)
要是你眼神足夠好, 在這棵小草里面, 你會(huì)看到一個(gè)小芽, 這小芽以后會(huì)長大, 變成一顆幼苗的莖。你還可能看到一個(gè)非常小的尖兒, 這個(gè)尖兒以后會(huì)往下長, 長成幼苗的根。
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, 大豆的種子, 自己也是一棵小草, 有葉子, 有莖, 有根!下一課, 我們會(huì)學(xué)到, 一顆小小的種子, 是怎么長成那些高大的樹和草的。
