1. As the lungs exhale this waste, gas is expelled into the atmosphere. 当肺呼出这股废气,气体就被排到空气中。
2. Generally, you exhale on the effort, if doing weights, karate or boxing, and inhale on the return. 一般来说,如果你在做举重、空手道或拳击等运动用力时,你会呼气,然后吸气。
3. Without gravity to help circulate air, the carbon dioxide you exhale has a tendency to form an invisible cloud around your head. 如果没有重力帮助空气循环,你呼出的二氧化碳会在你头顶周围形成一个看不见的云状物。
