Sleep came to him in brief snatches.

他时睡时醒。

I heard snatches of the conversation.

我听到几段零星的谈话。

He whistled and sang snatches of songs.

他边用口哨吹边唱了几个歌曲的片段。

I only caught snatches of the conversation.

我只听到谈话的一些片段。

He lolled at his ease, humming, not unmelodiously, snatches of a rude song, and fingering a pack of cards.

他懒洋洋地靠在那里，嘴里哼着一支不怎么悦耳的粗鲁的歌，手里拿着一副纸牌。
