1·On the other hand, air turbulence increases because of the effect of skyscrapers on airflow.
另一方面，摩天大楼对气流的影响导致了空气湍流增加。
2·Coupled with these factors is the loss of the complex interactions among the muscles that can change the route of airflow from nose to mouth.
与这些因素相结合的是肌肉之间复杂的相互作用的丧失，这种相互作用可以改变从鼻子到嘴的气流路线。
3·It takes twice as much effort to breathe during sleep because of greater resistance to airflow in the airways and changes in the efficiency of the muscles used for breathing.
由于睡眠时呼吸道中的气流阻力更大，并且用于呼吸的肌肉效率有变化，所以在睡眠时呼吸需要用两倍的力气。
4·Its aerofoil shape provides lift, but a pilot needs to regulate the airflow over it in order to control the aircraft.
虽然机翼的外形提供了飞机的升力，但驾驶员还需要通过调节掠过机翼的气流来操纵飞机。
5·Although its aerofoil shape provides lift, a pilot needs to regulate the airflow over it in order to control the aircraft.
虽然机翼的外形提供了飞机的升力，但驾驶员还需要通过调节掠过机翼的气流来操纵飞机。
