它们挖掘剩下的择食留下的灌木丛。

I startled a little at the sight of him in civvies, rootling under his desk.

看到他穿着便装，在桌子底下翻找东西，吃了惊。

他把手伸进背包, 用手指穿过口袋, 取出三胶卷盒。

Hence the libraries and laboratories;the observatories; the splendid equipment of costly and delicate instruments which now stands on glass shelves, where centuries ago the grasses waved and the swine rootled.

因此，图书馆和实验室； 天文台；昂贵而精致的仪器现在矗立在玻璃架子上的华丽设备， 几世纪前草在挥舞着， 猪在上面扎根。
