蝴蝶是一种昆虫，我们看见，它的身体分成三部分，每个部分都是几个体节连在一起构成的。蝴蝶有三对分节的足，两对翅膀，都是从中间的部分“胸部”长出来的。

　　A butterfly has the ends of the two feelers which grow out of its head thick or club-shaped . The feelers of the moth have pointed ends.

　　蝴蝶头上长着两只触角，触角末端很粗，呈“棒状”。但是蛾子触角的末端是尖的。

　　In the head of the butterfly you can see two large eyes;but each of these eyes is really made of a number of small eyes joined together.

　　可以看到蝴蝶头上还有两只大眼睛，但是这两只眼睛，其实都是由很多小眼睛聚在一起构成的。

　　Did you ever notice how the butterfly flies? It does not go straight, but always flutters from side to side. That way of flying makes it more difficult for any bird to catch it. Some birds kill and eat butterflies; but the butterfly when chased very often makes its escape, because of the funny way in which it flies.

　　你注意过蝴蝶是怎么飞的吗？蝴蝶不是直线飞行的，而是左右来回飘动的。这种飞行方式，让鸟类更不容易抓住它。有些鸟可以把蝴蝶杀死吃掉，但是鸟追蝴蝶的时候，蝴蝶经常能够逃跑，就是多亏了它这种奇怪的飞行方式。

　　I have often seen a bird chase a butterfly for a long distance without being able to catch it. If you have ever seen a game of football, you will know what I mean when I say that the butterfly is a good dodger .

　　我经常见到鸟儿追蝴蝶追得很远，最后却还是抓不着蝴蝶。小朋友如果看过足球比赛，就知道我说“蝴蝶很会躲闪”是什么意思啦！

　　In hot countries, there are butterflies which are as large as the palms of your two hands put together. And these insects are often of curious shapes, and have very pretty colours.

　　在一些炎热的国家，蝴蝶可以长到你的两只手掌并在一起那么大。这些昆虫还经常拥有奇怪的形状和非常艳丽的颜色。
