Its velvety blackness reveals the impenetrable opaqueness of the ink. It commands our attention.

如天鹅绒一样柔软光滑的黑色图像显示着墨无法穿透的黝暗，紧紧抓住了观众的视线。

When the old man had gaffed her and clubbed her, holding the rapier bill with its sandpaper edge and clubbing her across the top of her head until her color turned to a color almost like the backing of mirrors, and then, with the boy's aid, hoisted her aboard, the male fish had stayed by the side of the boat.

老人用鱼叉刺母鱼，再握住她那形如茅钩、边缘却粗糙如砂纸的尖嘴，用棒棍朝母鱼的头顶打，直到她变成如镜背一般黝暗的颜色为止。然后小男孩帮忙一起将她拖到船上，那条公鱼还一直在船边徘徊留连。

它靠得那么近，使得老人害怕它会用那大小和形状都像把大镰刀的锋利尾巴把鱼线剪断。老人用鱼叉刺母鱼，再握住她那形如茅钩，边缘却粗糙如砂纸的尖嘴，用棒棍朝母鱼的头顶打，直到她变成如镜背一般黝暗的颜色为止。然后小男孩帮忙一起将她拖到船上，那条公鱼还一直在船边徘徊留连。

But there are also now hundreds of footnotes and exceptions and modifications to those two facts that make the big picture ever murkier.

但是现在也有数以百计的脚注和例外和针对那些的修正二种使大的照片曾经变成更黝暗的事实。
