“冷笑地”可以翻译为 “coldly and scornfully” 或者更简洁地表达为 “with a cold/mocking smile” 。
“coldly and scornfully” 直接描述了冷笑时可能伴随的冷漠和轻蔑态度。
“with a cold/mocking smile” 则更具体地描绘了冷笑时的面部表情，即带着一种冷漠或嘲弄的微笑。
在实际使用中，可以根据语境选择最合适的表达方式。例如：
He looked at her coldly and scornfully, as if she were nothing to him.（他冷笑着轻蔑地看着她，仿佛她对他来说一文不值。）
She replied with a cold smile, not bothering to hide her disdain.（她冷笑了一声作为回应，连掩饰不屑的力气都懒得花。）
