不要驚慌！

Have you ever felt pure fear， a fear that makes you act in a way you normally would not？

That is panic. Panic is a great fear that makes otherwise normal people do abnormal things.

To hit the panic button means to panic suddenly. Another common expression is widespread panic. It describes an event that causes panic among large numbers of people. For example， “The spread of disease caused widespread panic throughout Europe during The Middle Ages.”

The origin of the word panic comes from the Greek word “panikos.”According to Greek myth， Pan was the god of flocks and shepherds. Greek legend says that Pan was half human and half goat. He lived in the woods and in the fields. His angry voice was so scary that it caused panic to anyone who was unlucky enough to be nearby.

According to one Greek myth， Pan fell in love with a beautiful nymph[居住在山林水澤的仙女]. A nymph is a spirit that takes the shape of a young woman and lives in the mountains， forests， meadows and water. Pan tried to capture her， but she ran away. The nymph hid in a river taking the form of a reed[蘆葦]， a thick， hollow grass that lives in the water.

The wind made a song as it blew across the hollow reeds.

Pan did not know which reed was the nymph. So， he took a handful and joined them together side-by-side and carried it with him to hear the music it played. Today， we call this instrument a pan flute[排簫].

Of course， this is just the Greek story. Pan flutes also have a long history in Europe， Asia， Africa and the Americas.

Just like the pan flute， panic can be found everywhere.

Mental health experts treat people with panic disorders. The American Psychological Association defines a panic attack as “a sudden surge of overwhelming， or extreme， fear that comes without warning and without any obvious reason.”

The word panic also describes economic or financial disasters.

The most infamous financial panic in the U.S. was the stock market crash of 1929. Some people on Wall Street where stocks were traded were so panicked that they jumped from their office windows.

Panic is also a great literary tool.

Jack London was an American writer who wrote “The Sea Wolf.” He left school at age 14 to become a seaman. Published in 1904， “The Sea Wolf”has a panicked ship-wreck scene that is partly based on Mr. London’s experience as a sailor in the Pacific Ocean.

Two ships crash together in the ocean. Women passengers scream with panic as the ship goes down into the freezing ocean waves. As one man finds himself adrift alone in the sea， another type of panic takes hold of him.

“I was alone. I could hear no calls or cries—only the sound of the waves， made weirdly hollow and reverberant[回響的] by the fog. A panic in a crowd， which partakes of a sort of community of interest， is not so terrible as a panic when one is by oneself； and such a panic I now suffered. I confess that a madness seized me， that I shrieked aloud as the women had shrieked， and beat the water with my numb hands.”

Panic is a powerful tool in myth or literature but not so much in real life. So， next time you feel extreme fear taking hold of you， causing you to lose all reason， remember to remain calm. And don’t panic.

hit the panic button 喻指一時慌亂或驚慌失措。據說第二次世界大戰期間，美國轟炸機的駕駛員在飛機受損的緊急情況下按動緊急按鈕（panic button）通知機上人員降落。后來口語中用hit（或push）the panic button表示驚惶失措，即一個人遇到緊急或者異常情況時手忙腳亂，不知所措，就如機師亂按緊急按鈕，生動地描繪出“失酷（失去冷靜）”（lose one’s cool）的動作。口語中叫人不要驚慌的例子如：Don’t go hitting the panic button， I’m sure you can solve the problem with a little rational thought.（不要驚慌，我相信你稍微理智地考慮一下就能解決問題。）Hit （Push） the panic button亦作Press the panic button。

widespread panic 意思是廣泛的恐慌。

panic disorders意思是恐慌紊亂，驚恐癥。

panic attack是指急性焦慮癥，又稱驚恐發作。患者突然感到恐懼，猶如大難臨頭或死亡將至，從而失去自控能力而尖叫逃跑、躲藏或呼救。
