有在加拿大的帅哥美女吗？

 这么冷！零下64摄氏度。不能说悄悄话，也不能玩做迷藏了。

“Sound does not travel in the same way at different temperatures. As well as moving slower in the cold, sound also travels further, if you happen to be near to the ground. When air near the ground is cold and the air above it is warm, sounds are refracted by the warm air toward the surface. The sound then bounces between the ground and the warm air, traveling much further along the ground than in warmer temperatures.”

“Adding to the disorientating effect of hearing conversations from miles away, and the icy fog that surrounded them and diminished their vision, people in the town could see clouds of their frozen breath linger in the air for minutes at a time.”
