with grey eyebrows and hoary hair

尨眉皓───Show your eyebrows;发───hair

Watch just one show, and I swear you'll be scanning your dates, coworkers and neighbors for flashes of twitchy eyebrows, erratic blinks and one-shouldered shrugs.───我发誓只要看一集，你的脑中会开始闪过你的约会对象，同事，邻居的每一个挑眉，每一个闪烁的眼神，每一个不自觉的耸肩。

Show you're listening by your nonverbal communication. You might nod, shake your head, or raise your eyebrows. Adjust your posture accordingly. Make eye contact.───用你的肢体语言表明你正在聆听。你可以选择点头、摇头、扬眉毛等根据场景来调整你的姿势来表明你正在聆听。当然，有时候聆听者和倾述者眼神的交流是有必要的。
