They created an extraordinary stone implement, a large teardrop-shaped hand ax whose design and symmetry reveal a keen sense of aesthetics.

他们创造了一种非凡的石器，一种巨大的泪滴形手斧，其设计和对称性显示出敏锐的美感。

This tirade had left Mr. Phillipps unimpressed; he considered Dyson as hopeless, and he went home to gloat over some primitive stone implements that a friend had sent him from India.

这番长篇大论让菲利普斯先生无动于衷。他认为戴森没有希望，于是他回到家中，幸灾乐祸地看着一位朋友从印度送给他的一些原始石器。

On another occasion I tried the experiment with a clever woodman of the place; but this man, who had handled his axe for forty years, could do nothing with the stone implement, and missed every stroke most ludicrously.

还有一次，我和当地一个聪明的樵夫一起做了这个实验。而这个用了四十年斧头的人，却对石器无能为力，一刀不中，可笑至极。
