On the terrace was a broad wooden bench running round the walls.

露台上有一张宽阔的木凳，围着墙壁。

They were standing on the topmost tier of what seemed to be stone benches running all around the room and descending in steep steps like an amphitheatre, or the courtroom in which Harry had been tried by the Wizengamot.

石头台阶环绕着整个屋子，如同石凳，一级一级逐渐下降，每一级都很陡峭，就像是阶梯教室，或是哈利曾被威森加摩审问过的审判室，他们所站的位置处于最高一级台阶上。
