May darkness and gloom claim it, clouds settle upon it, the blackness of night affright it!

愿黑暗和阴影玷污它，浓云遮盖它，白昼失光的晦暗惊吓它。

The city was aflutter with preparations for four days of parties and pomp, shadowed at every turn by layer upon layer of security.

"Albacore," he said aloud.

老人为了同情它这般惨状，往它头上打了一下又踢了它几下，然而它的身体依然在船尾的阴影里中颤抖着。

In each SFS algorithm,parameters of the source direction and albedo of the surface are required.

在SFS(基于阴影的三维表面重构)各种算法中，都需要光源方向及曲面反射率。

I can understand him, all of a sudden a such a thing, he certainly has the shadow.

我能理解他，一下子出了这样的事，他肯定有阴影的。

If your going to try the cross-hatch style of quick shading, might I suggest that you further alternate and think about your angles a bit more (going 90 degress and making a checkboard pattern is kind of flat to me), it can be pretty powerful and descriptive if you stroke in the direction the form flows...might need to make your lines closer together so its more consistent.

如果你打算用交叉的平行线画出阴影，我建议你更多的交替线条而且角度多一点（90度递减还有画的格子图案对我来说跟平的一样），如果你每一笔的描绘都形成流动性方向，它可能会变的更有力度和描绘性，也许会让你的线条更紧密而且更连贯。

Ama,"I shall purge this land of the shadow."

"我要把这片大地从阴影中拯救出来。"
