1. My head was going thrum thrum thrum. 我的脑袋嗡嗡嗡地响着。
2. And mooring cables would thrum in the currents, like a guitar string. 固定用的缆索，像吉他弦一样，在水流中会振荡出声。
3. The clop of their hooves sounds oddly bucolic against the throaty thrum of helicopters overhead. 对照头顶上直升机的低沈声响，马蹄声听起来带有奇特的田野风味。
4. An example is the S/s gene, which determines pin(s) and thrum (S) style length in certain species of Primula. 例如报春属植物中决定花柱长短为针式型（s）还是线式型（S）的S/s基因。
5. In this sedate garrison town ringed by jagged peaks, the gentle thrum of the day is usually reduced to a whisper by night. 在这个群峰环绕、安详的卫戍小镇上，白天温柔的声响总是变成夜间温柔的窃窃私语。
