We all know that fish live inwater. But， there is a kind of fishwhich lives in the desert.Difficult to believe？ Well， there isa kind of fish called the lungfish， which are found in Africa. When the riversoverflow2， their water goes to the dry places around. It makes small lakes. Thefish lives in these lakes.

And， when the lakes dry up， the lung fish don’t die. They bury3 themselves inthe wet mud4 where they can live for months. Specially， if they go deep underground.Sometimes， these fish have been found several metres under the ground.

Lungfish are one of the oldest fishes found on earth today. They are verymuch like the fish that lived 200 million years ago at the beginning of theMesozoic era. It was a time when dinosaurs， fish， flying reptiles5 and evergreentrees were found on the Earth.

我們都知道魚生活在水中。但是，有一種魚生活在沙漠中。

難以置信？好吧，有一種魚叫肺魚，產(chǎn)于非洲。當(dāng)河水泛濫時，河水會流到周圍干燥的地方，形成小湖。這種魚生活在這些湖里。

但是，當(dāng)這些湖泊干涸時，肺魚不會死亡。它們把自己埋進(jìn)濕泥里，特別是如果它們深入地下，那它們可以在那里生存幾個月。有時，這些魚在地下幾米處被發(fā)現(xiàn)。

肺魚是當(dāng)今地球上發(fā)現(xiàn)的最古老的魚類之一。它們非常像生活在兩億年前中生代初期的魚。那是地球上出現(xiàn)恐龍、魚類、飛行爬行動物和常青喬木的時期。
