sit-downs

Brandon Overstreet, a doctoral candidate in hydrology at the University of Wyoming, picked his way across the frozen landscape, clipped his climbing harness to an anchor in the ice and crept toward the edge of a river that rushed downstream toward an enormous sinkhole.

怀俄明大学（University of Wyoming）水文学博士研究生布兰登·奥弗斯特里特（Brandon Overstreet）在这片冰面上小心翼翼，将他的安全带系到冰层中的一个锚上，朝着一条向下流入巨大深坑的河流的边缘徐徐前进。

Thou knowest my downsitting and mine uprising , thou understandest my thought afar off.

2我坐下,我起来, 你都晓得.你从远处知道我的意念.

Downstairs are two small rooms: a kitchen and a sitting room.

楼下是两个小房间：一个厨房和一个起居室。
