Then the inventor Henry Bessemer discovered that directing a blast of air at melted iron in a furnace would burn out the impurities that made the iron brittle (易碎的). As the air shot through the furnace, the bubbling metal would erupt in showers of sparks. When the fire cooled, the metal had been changed, or converted, to steel. The Bessemer Converter made possible the mass production of steel. Now three to five tons of iron could be changed into steel in a mater of minutes.
Just when the demand for more and more steel developed, prospectors, discovered huge new deposits of iron ore in the Mesabi Range, a 120-mile-long region in Minnesota near Lake Superior. The Mesabi deposits were so near the surface that they could be mined with steam shovels.
Barges and steamers carded the iron ore through Lake Superior to depots (车站) on the southern shores of Lake Michigan and Lake Erie. With dizzying speed, Gary, Indiana, and Toledo, Youngstown, and Cleveland, Ohio, became major steel-manufacturing centers. Pittsburgh was the greatest steel city of all.
Steel was the basic building material of the industrial age. Production skyrocketed from seventy-seven thousand tons in 1870 to over eleven million tons in 1900.
According to the passage, the railroad industry preferred steel to iron because steel was ______.
A．cheaper and more plentiful
B．lighter, and easier to mold
C．cleaner, and easier to mine
D．stronger and more durable

Earth's Inner Core
Scientists have" long struggled to understand What lies at the planet's center. Direct observation of its center is impossible, so researchers must ___________ (51) to other evidence.
In 1889, a German scientistdetected a severe earthquake in Japan. Geophysicists concluded that shock waves___________ (52) jolts(晃动) from one side of Earth through the center to the other side. Then in 1936, Danish geophysicist Inge Lehmann studied the waves'___________ (53) to determine that within Earth's core of molten (熔化了的)iron lies a solid inner core-- But___________ (54) that core was made of eluded (难倒)her, Other geophysicists quickly determined that Lehmann's inner core was composed mostly ___________ (55) iron. Since then, Lehmann's discovery has ___________ (56)conventional Earth science.
But now scientists are challenging traditional theory with new and radical___________ (57). For example, Earth's center could actually contain an "inner core within the inner core," claim Ishii and colleague Adam Dziewonski.
Analyzing hundreds of thousands of earthquake wave___________ (58), they maintain that the inner core has at its heart a tiny, even more solid sphere(球体). This sphere "may be the oldest fossil ___________ (59) from the formation of Earth," says Dziewonski.
Dziewonski and Ishii speculate that shortly___________ (60) Earth formed around 4.8 billion years ago, a giant asteroid (小行星) smashed into the young planet and nearly melted it. But Earth's center didn't quite melt; it___________ (61) mass as the planet cooled. The core within a core may B．e the kernel (核心) that endured. "Its presence could change our basic ideas about the___________ (62) of the planet," Dziewonski says.
Dziewonski's idea is tame (温和的) compared to the ___________ (63) theories of independent geophysicist J. Marvin Herndon. Earth's inner core is made not of iron, he claims, but a ___________ (64) of nickel and silicon. Herndon has a truly revolutionary notion: Within the nickel silicide(硅化物) inner core is also.an "inner" inner core -- an 8 kmowide ball of the element uranium. Uranium is radioactive. Herndon thinks the uranium releases heat energy as its atoms ___________ (65) fission-split and crash into one another in a chain reaction. In other words, we may live on top of a gigantic, "natural"nuclear power plant.
