摘要
一些温度计的最低刻度达到﹣40℃。可是实际上,温度计里面的水银柱是走不到那么低的位置的,因为在那个温度,水银会结冰。但在我们的地球上,有很少几个地方会冷到那种程度。世界上最冷的地方并不是北极,而是一个叫作西伯利亚的地方。在那儿,温度可以降到﹣40℃,温度计一定会被冻僵。
Some thermom eters have numbers down to forty degrees(40℃)below zero.There the numbers stop,for when the mercury gets down to that point it freezes up.But there are few places in the World where it ever gets as cold as that.The coldest place in the World is not at the North Pole;the coldest place in the World,where the thermometer does go below 40℃and freezes up,is called Siberia.
