第58課 毛毛蟲向前爬
All birds lay eggs. If the eggs are kept warm, after a certain time a little bird, just like the parent birds, comes out of each egg.
鳥兒都會下蛋。如果鳥蛋能保持溫暖，過一段時間，長得很像爸爸媽媽的小鳥就會破殼而出。
All insects also lay eggs. But these eggs do not produce perfect insects. Out of each tiny egg there comes a small, soft creature, which looks somewhat like a little worm, and is known as a maggot, a grub, or a caterpillar.
所有的昆蟲都會“產(chǎn)卵”，但這些蟲卵可不會孵出成蟲。每個細(xì)小的蟲卵里出來的，都是軟軟的小動物，看上去像“小肉蟲子”，英語的名字分別叫maggot, grub, caterpillar。
The eggs of flies produce maggots; the eggs of most beetles produce grubs; the eggs of butterflies and of moths produce caterpillars. Maggots have no legs, and it is not easy to tell which end of their body is the head. Grubs have either no legs at all, or at most six legs.
蒼蠅的卵孵出來的是maggot(也就是蛆);多數(shù)甲蟲產(chǎn)的卵孵出來的是grub(鞘翅目幼蟲);蝴蝶和蛾子產(chǎn)的卵孵出來的是caterpillar(鱗翅目幼蟲)。蛆沒有腿，也不容易看出來身子哪一端是腦袋。鞘翅目幼蟲要么沒有腿，要么最多有六條腿。
But caterpillars have not only six true legs; on the hinder part of their bodies they have a number of what we may call false feet—little fleshy things which are very useful in helping the caterpillar to move about, or to hold on to the twigs of trees.
但是鱗翅目幼蟲不只有六條真正的腿，在身體的后半邊，還有一種叫“假腳”的東西——肉做的小小突起，這些東西很有用，能幫助幼蟲到處爬，還能幫助它抓住小樹枝。
I should like you to keep some caterpillars. They will need looking after and feeding, but they will repay you for your trouble, if you watch their funny ways and the curious changes that they pass through.
小朋友，請你也養(yǎng)一些鱗翅目的幼蟲吧!它們需要好好照顧，好好喂養(yǎng)，但是也會回報你的辛苦，如果你觀察到它們有趣的生活，還有奇妙的變化。
For a few pence, you can buy a hundred silk-worms'eggs. If you keep them in a warm place for a few days, they will change to caterpillars. These will then need to be fed with mulberry leaves or lettuce leaves.
幾個便士就可以買到100顆蠶卵。把蠶卵放在暖和的地方，過幾天，就會孵出幼蟲，這些幼蟲要喂桑葉和萵苣葉。
