世界小史 第8章:伟大的发明家

 　　Chapter 2 The Greatest Inventors of All Time

　　第二章 前所未有的最伟大的发明家

　　Near Heidelberg, in Germany, somebody was once digging a pit when they came across a bone, deep down under the ground.

　　有一次有人在德国海德堡附近挖一个坑，人们在那儿的地下深处找到了一块骨头。

　　It was a human bone. A lower jaw¹.

　　一块人的骨头。一块下颌骨。

　　But no human beings today have jaws² like this one.

　　但现在没有人有这样的下颌骨了。

　　It was so massive and strong, and had such powerful teeth!

　　它十分坚固而结实，那上面的牙齿十分强劲有力！

　　Whoever owned it must have been able to bite really hard.

　　这块下颌骨所属的那个人啃咬起食物来一定很有劲。

　　And must have lived a long time ago for the bone to be buried so deep.

　　这一定是很久以前的事了，因为这块骨头在地下埋得这么深。
