Lesson 29 The Fly

第29課蒼蠅

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, 你在窗玻璃上經(jīng)?？匆?jiàn)的普通蒼蠅, 叫“家蠅”, 英語(yǔ)是house-fly。那種特別喜歡吃肉的大蒼蠅, 叫“麗蠅”。

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.

麗蠅和家蠅是不一樣的。蒼蠅在變成蒼蠅之后, 就再也不長(zhǎng)個(gè)兒了, 所以小蒼蠅和大蒼蠅不可能是同一種。

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.

你知道蒼蠅為什么叫“昆蟲(chóng)”嗎? 因?yàn)樯n蠅的身體是三部分組成的, 三個(gè)部分之間, 看起來(lái)就像要被切開(kāi)一樣：頭部、胸部、腹部。昆蟲(chóng)的英語(yǔ)叫insect, 意思就是“切進(jìn)去”。蒼蠅的身體看上去也好像是“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.

蒼蠅的身體里沒(méi)有骨頭, 但是外面有一層甲殼一樣的硬皮, 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.

看看蒼蠅的頭。你看見(jiàn)它的兩只大眼睛了嗎? 這兩只大眼睛可以看到每一個(gè)方向。頭上還有兩根觸角, 像兩把刷子一樣, 突出在腦袋前面。

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.

蒼蠅的嘴是一個(gè)“小象鼻”或“管子”, 就跟一頭非常小的象的鼻子一樣。觀察一下, 蒼蠅落在一團(tuán)濕潤(rùn)的糖上, 就能看見(jiàn)它伸出嘴來(lái)吸食糖水。
