One way to know if someone is listening carefully is by looking at their body language. For example, if they keep eye contact with you and sometimes nod or smile, it shows they are paying attention. Also, if they lean forward a bit, it means they are interested in what you are saying. Their posture is usually open and relaxed, not closed off.
判断某人是否在认真聆听的一种方法是观察他们的肢体语言。例如,如果他们一直与你保持眼神交流,有时点头或微笑,这表明他们在专注听讲。此外,如果他们稍微向前倾,这意味着他们对你所说的内容感兴趣。他们的姿势通常是开放和放松的,而不是封闭的。
