But I never knew this. " Yep. Now come up here and let me teach you how to use this circular saw."

但我从来不些。“是。现在上来，让我教你如何使用个圆锯。”

Do me a favor and help me cut this two-by-four, will ya? Pass me the circular saw, and grab hold of the end of the board.

帮我一下忙吧，把个截宽四寸厚二尺，可以吗？给我一下那个圆锯，然后抓住块木头那端。

Not to speak of the great circular saw that had to be set in its course to the nicety of a pencil line, never swaying east nor west, lest it should fly asunder.

更不用说巨圆锯了，它必须在其路线上精确设置为铅笔线，从不向东或向西摇摆，以免它飞散。
