Once, indeed, my heart was in my mouth, but only once.

的确，我的心曾经挂在嘴边， 但只有一次。

My heart was in my mouth as I waylaid a steward and asked if a Mr. Raffles was on board.

当我拦住一名乘务员并询问莱佛士先生是否在船上时， 我的心都悬在嘴边了。

" Here goes, " I said, stepping out; but I confess my heart was in my mouth as I thought of going through the heart of that monstrous herd.

" 干。" 我说着便踏了出去。 但是我得承认，一想起要从那一群可怕的海豹之间穿过，我的心便仿佛跳到了嘴里。
