Sneezing is a way to remove the irritants inside the throat and the nose. It is natural and involuntary, which is often beyond the control of the person who is sneezing. The person may become more relaxed after sneezing. However, sneezing can be annoying to people nearby.
Sneezing can be noisy and the person may spread germs for failing to cover one’s mouth. Hence, it is necessary to be considerate by covering the mouth and attempting to lower down the noise caused by sneezing.
Beside the above, it is also necessary to be cautious when sneezing. Without precaution, a person may even cause harm to one’s body through sneezing. Two days ago I sneezed loudly and carelessly, and consequently I hurt my back. It was almost like twisting my backbone. Due to the back pain, I couldn’t move my body freely as I used to be. Hence, for the sake of one’s own health, we have to sneeze cautiously.
打喷嚏是一种消除喉咙和鼻子里刺激物的方法。这是自然的，也是身不由己的行为，因此往往非打喷嚏的人能完全控制。打喷嚏后，人可能会变得轻松；然而打喷嚏常会让附近的人感到烦恼。
打喷嚏可能会很吵，而那个人可能会因为没有捂住嘴而传播细菌。所以有必要通过遮住嘴并试图降低由打喷嚏引起的噪音。
除此之外，打喷嚏时也要小心。没有预防措施，一个人甚至可能通过打喷嚏对自己身体造成伤害。两天前，我大声地，不经意地打喷嚏，因此我伤了背。这几乎就像扭曲了我的背骨，而由于背部疼痛，我不能像过去那样自由地移动身体。因此，为了自己的健康，我们必须尽可能小心地打喷嚏。
