Animals have interesting life cycles. Lets learn about them！

動(dòng)物的生命周期非常有趣。讓我們一起學(xué)習(xí)吧！

Animals are born， grow， and change. This is called their life cycle.

動(dòng)物出生、成長(zhǎng)和變化，這就是它們的生命周期。

A butterfly starts as an egg. It becomes a caterpillar and eats alot. Then， it turns into a pupa. Finally， itcomes out as a beautiful butterfly.

蝴蝶從一個(gè)卵開始。它變成毛毛蟲，并且吃很多東西。然后，它變成了蛹。最后，它變成了一只美麗的蝴蝶。

Frogs start as eggs too. They grow into tadpoles with longtails. Tadpoles swim in water. Then， they grow legs and becomefroglets. Soon， they are full-grown frogs.

青蛙也從卵開始。它們長(zhǎng)成有長(zhǎng)尾巴的蝌蚪。蝌蚪在水里游泳。然后，它們長(zhǎng)出了腿，變成了青蛙幼崽。很快，它們長(zhǎng)成了成年青蛙。

Different animals have different life cycles. Its amazing to see how they change！
