活恐龙

What are living dinosaurs? Crocodiles and lizards have been living on earth for millions of years. They were living at the same time as the dinosaurs. We know this because people have dug up their bones.

什么是活恐龙呢？ 鳄鱼和蜥蜴已经在地球上生活了几百万年啦。 它们和恐龙曾经生活在同一个时代哦。 我们知道这些是因为人们挖出过它们的骨骼化石。

One of the reasons crocodiles and lizards have survived so long is that they are good hunters and scavengers.

鳄鱼和蜥蜴能存活这么久的原因之一，是它们既是优秀的猎手，也是能干的食腐动物。

Crocodiles today. In Africa, herds of animals cross the River Mara each year, looking for fresh grass to eat. Nile crocodiles lie in wait for them.

现在的鳄鱼。在非洲，每年都有成群的动物横渡马拉河， 寻找新鲜的青草吃。尼罗河鳄就潜伏在河里等着它们送上门。

Large crocodiles only need a few big meals a year. The rest of the time, they mostly eat fish. Some crocodiles lie waiting for many months until an unlucky animal tries to cross the river.

大型鳄鱼一年只需要吃几顿大餐就够了。 其余的时间，它们大多以捕鱼为食。 有些鳄鱼会潜伏等待好几个月 直到有倒霉的动物试图过河。

Crocodiles are some of the best hunters in the world. They are good at sneaking up on their prey. Eyes, nostrils and ears are on top of their heads, so they can swim without being seen.

鳄鱼是世界上最厉害的猎手之一。 它们特别擅长偷偷靠近猎物。 它们的眼睛、鼻孔和耳朵都长在头顶， 所以游泳的时候不会被猎物发现。
