英國學(xué)生科學(xué)讀本 Lesson 93 蝌蚪與青蛙(2)
現(xiàn)在, 蝌蚪能夠爬行了, 而且可以像人類一樣進(jìn)行呼吸。因此, 它們會離開池塘, 進(jìn)入到潮濕的草地中生活。
Its tail becomes still shorter, and soon disappears.
它的尾巴會變得更短, 然后便消失不見了。
Now it is no more a tadpole; it has become a young frog.
這時, 它不再是蝌蚪, 而是發(fā)育成為幼年青蛙。
Every one must have seen frogs jumping about in the wet grass by the roadside on a summer evening.
大家肯定都在夏季傍晚時候的路邊濕草地里, 看到過一蹦一跳的青蛙。
They are quite harmless, and you may take one in your hand without any fear.
它們不會對我們造成任何威脅, 因此你不必害怕, 可以拿起來放在手中仔細(xì)觀察。
But if you do pick one up to look at it, be very careful not to hurt it.
然而, 如果你真的這樣做, 請不要弄傷它。
Look at the squat, stumpy body of the animal, with its very short neck and three-cornered head.
你可以看到它矮胖、粗短的身體, 短短的脖子以及三角形的腦袋。
The frog is about two or three inches in length, and is mottled with brown and yellow on the back; but it is lighter in colour underneath.
青蛙的體長大約在兩到三英寸, 背部長滿了棕黃色的斑點;但是它的腹部顏色卻比較明亮。
The skin has no fur or hair, but it is covered with a slimy fluid.
青蛙的皮膚上沒有任何毛發(fā), 但是卻覆蓋著一層黏滑的液體。
The two hind legs are long and Strong. Each of the hind feet has five toes, which are joined by a web.
青蛙的兩條后腿又長又壯, 每只后腳都有五根腳趾, 通過蹼連接在一起。
The two front legs are much shorter and weaker.
兩條前腿較短, 也遠(yuǎn)沒有那么粗壯。
The front feet have only four toes each, and they are not webbed.
前腳只有四根腳趾而且沒有蹼。
The limbs of the frog remind us of those of the rabbit;
青蛙的四肢與兔子頗為相似,
for with both these animals it is the hind legs which do most of the work in helping them to move about.
因為這兩種動物都主要依靠后腿進(jìn)行運動。
The frog has no tail; and although it has a backbone, it has no ribs.
青蛙沒有尾巴;雖然長有脊柱但是卻沒有肋骨。
Its two eyes are large, and stand far out from its head.
青蛙的兩只眼睛很大而且突出在腦袋之外。
Each eye has two eyelids, the under eyelid being made of thin and clear skin.
每只眼睛都長有兩層眼皮, 下面那層眼皮由輕薄的透明皮膚構(gòu)成。
The frog has a large mouth; but as it does not chew its food, it has only a few tiny teeth in its upper jaw.
青蛙的嘴巴很大;但是, 它很少會咀嚼食物, 因此只有在上腭處長有幾顆小牙齒。
