Lesson 29 The Fly
第29课 苍蝇
The common fly which you so often see on the window-panes is called the house-fly. The large flies which are so fond of meat are called blow-flies.
小朋友, 你在窗玻璃上经常看见的普通苍蝇, 叫“家蝇”, 英语是house-fly。那种特别喜欢吃肉的大苍蝇, 叫“丽蝇”。
They are not the same as the housefly. A fly never grows bigger after it has become a fly, so that small fliesand large flies cannot be of the same kind.
丽蝇和家蝇是不一样的。苍蝇在变成苍蝇之后, 就再也不长个儿了, 所以小苍蝇和大苍蝇不可能是同一种。
Do you know why the fly is called an insect? It is because its body is made up of three parts, which are nearly cut apart from one another—the head, the chest, and the belly. The word insect means cut into, and the fly's body looks as if it had been nearly cut into three pieces.
你知道苍蝇为什么叫“昆虫”吗? 因为苍蝇的身体是三部分组成的, 三个部分之间, 看起来就像要被切开一样：头部、胸部、腹部。昆虫的英语叫insect, 意思就是“切进去”。苍蝇的身体看上去也好像是“切”成三部分的。
Flies have no bones inside their body; but they have a hard skin like a shell all over the outside, and their flesh is inside this hard skin.
苍蝇的身体里没有骨头, 但是外面有一层甲壳一样的硬皮, 硬皮的里面是肉。
Look at the head of the fly. Do you see its two large eyes, with which it can see on every side? Then it has two feelers, which stick out in front like little brushes.
看看苍蝇的头。你看见它的两只大眼睛了吗? 这两只大眼睛可以看到每一个方向。头上还有两根触角, 像两把刷子一样, 突出在脑袋前面。
The mouth of the fly is a little trunk or tube, like the trunk of a very tiny elephant. Watch a fly when it rests on a lump of sugar, and you will see it putting out its trunk and sucking up the sweet juice.
苍蝇的嘴是一个“小象鼻”或“管子”, 就跟一头非常小的象的鼻子一样。观察一下, 苍蝇落在一团湿润的糖上, 就能看见它伸出嘴来吸食糖水。
