"Breathlessness"在英文中通常指的是呼吸困难，即当你试图呼吸时却感到窒息或无法吸入足够的空气。
在英文范文中有许多使用"breathlessness"的例子，例如：
"The runner's face was flushed, his breath coming in gasps, his body trembling with the effort of the race. He felt breathless, as if he couldn't catch his breath, and he knew that he had to keep going."（这位跑步者的脸红扑扑的，气喘吁吁，身体因比赛的努力而颤抖。他感到呼吸困难，仿佛无法呼吸，并且他知道他必须继续前进。）
又如："She sat there, her breath coming in shallow gasps, her heart pounding in her chest as she tried to process what had just happened."（她坐在那里，呼吸急促，心跳加速，试图理清刚刚发生的事情。）
以上两个例子都描述了人们在经历紧张、兴奋、恐惧或疲劳等情况下所感受到的呼吸困难。
breathlessness的意思是“气喘，气急，呼吸急促”。
例句：He was so breathless that he could hardly speak.
他气喘吁吁，几乎说不出话来。
breathlessness的意思是气喘，气急，呼吸急促；在英文范文中的最新变化可能指的是一种呼吸困难的症状，可能由许多因素引起，如呼吸系统疾病、心脏病等。
