Inner Earth 地球核心
If you have _1_ dreamed of journeying(v.旅行) to the center of the earth, don't hold your breath(屏息而待). It is almost 4,000 miles below us, roughly(大約) the distance from Chicago to London. But in this scenario(n.情形), nobody has even left the suburb(n.市郊). The deepest mines(n.礦) in the world are the western deep levels goldmines in South Africa. They descend(v.下降) 2.3 miles into the earth, _2_ the temperature is a sweltering(悶熱的) 130 degrees Fahrenheit _3_ by warm rocks below. With a shaft(礦坑) so deep, the miners have to descend in several stages(階段). The deepest hole ever drilled(v.鑽) is here at Kola in Russia(蘇俄). It extends 7.5 miles down. This drill is so long _4_ it distorts(v.變形) like a piece of elastic(橡皮筋). But even the deepest drilled hole is still _5_ 3,955 miles short of the center of the earth -- barely(adv.僅僅) a pin(大頭針) prick(刺) _6_ the surface of our planet(n.行星).
The earth is like an onion _7_ up of different layers(n.層) of material. The crust(n.地殼) is a thin layer of rock a few tens of miles' thick. The largest region(n.區域) of the earth's interior(n.內部) is called the Mantle. It's almost 1,800 miles of a patty(餡餅)-like rock. But beneath(在下) the Mantle, the core(n.核心) is roughly the size of the moon. And it is made _8_ of two parts -- the liquid(a.液體的) metal(n.金屬) outer core and the solid(a.固體的) metal inner core. [國家地理雜誌]
