（单词翻译）

 　　The tadpole1 is now able to walk, and to breathe the air just as we do, so it crawls out of the pond and lives in the damp grass. 现在, 蝌蚪能够爬行了, 而且可以像人类一样进行呼吸。因此, 它们会离开池塘, 进入到潮湿的草地中生活。

　　Its tail becomes still shorter, and soon disappears. 它的尾巴会变得更短, 然后便消失不见了。
　　Now it is no more a tadpole; it has become a young frog. 这时, 它不再是蝌蚪, 而是发育成为幼年青蛙。
　　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时候的路边湿草地里, 看到过一蹦一跳的青蛙。
　　They are quite harmless, and you may take one in your hand without any fear. 它们不会对我们造成任何威胁, 因此你不必害怕, 可以拿起来放在手中仔细观察。
　　But if you do pick one up to look at it, be very careful not to hurt it. 然而, 如果你真的这样做, 请不要弄伤它。
　　Look at the squat2, stumpy body of the animal, with its very short neck and three-cornered head. 你可以看到它矮胖、粗短的身体, 短短的脖子以及三角形的脑袋。
　　The frog is about two or three inches in length, and is mottled with brown and yellow on the back; but it is lighter3 in colour underneath4. 青蛙的体长大约在两到三英寸, 背部长满了棕黄色的斑点；但是它的腹部颜色却比较明亮。
　　The skin has no fur or hair, but it is covered with a slimy fluid. 青蛙的皮肤上没有任何毛发, 但是却覆盖着一层黏滑的液体。
　　The two hind5 legs are long and Strong. Each of the hind feet has five toes, which are joined by a web. 青蛙的两条后腿又长又壮, 每只后脚都有五根脚趾, 通过蹼连接在一起。
　　The two front legs are much shorter and weaker. 两条前腿较短, 也远没有那么粗壮。
　　The front feet have only four toes each, and they are not webbed. 前脚只有四根脚趾而且没有蹼。
　　The limbs of the frog remind us of those of the rabbit; 青蛙的四肢与兔子颇为相似,
　　for with both these animals it is the hind legs which do most of the work in helping6 them to move about.  因为这两种动物都主要依靠后腿进行运动。
　　The frog has no tail; and although it has a backbone7, it has no ribs8. 青蛙没有尾巴；虽然长有脊柱但是却没有肋骨。
　　Its two eyes are large, and stand far out from its head. 青蛙的两只眼睛很大而且突出在脑袋之外。
　　Each eye has two eyelids10, the under eyelid9 being made of thin and clear skin. 每只眼睛都长有两层眼皮, 下面那层眼皮由轻薄的透明皮肤构成。
　　The frog has a large mouth; but as it does not chew its food, it has only a few tiny teeth in its upper jaw11. 青蛙的嘴巴很大；但是, 它很少会咀嚼食物, 因此只有在上腭处长有几颗小牙齿。
