I must have stood for a few moments listening to the whip and snap of the curtains and the groan of a picture on the wall.

我准是站了好会，倾听窗帘刮动的劈啪和墙上像嘎吱嘎吱的响。

The moment it broke free, there was a crack of thunder.

松脱出来的那瞬间，发出雷电般的劈啪。

About 3 o'clock that afternoon, the logjam began to break up, there was no warning just a loud cracking sound that got louder and louder as the rows of logs began to hit each other.

当天下三点左右，浮木比赛开始崩塌。排排原木开始互相撞击，没有任何征兆，只是巨大的劈啪，来大。

If I lay on my face the weight would come upon my spine, and I shuddered to think of that dreadful snap.

如果我是趴着的，重量就会落在脊椎骨上。想到那压断骨头时可怕的劈啪，我不禁浑身打起颤来。

The crackling turned into a snapping, the sled pivoting and the runners slipping and grating several inches to the side.

喀嚓变成了劈啪，雪橇转向左面，滑板有些松了，并且向侧吱吱地滑动了几寸。
