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_________(1)to other evidence.
In 1889,a German scientist detected a severe earthquake in Japan.Geophysicists
concluded that shock waves_________(2) jolts(晃动)from one side of Earth through
the center to the other side.Then in 1936,Danish geophysicist lnge Lehmann studied the
waves' __________ (3) to determine that within Earth's core of molten(熔化了的)iron
lies a solid inner core一but_________(4) that core was made of eluded(难倒)her.
Other geophysicists quickly determined that Lehmann's inner core was composed mostly
_________(5) iron.Since then,Lehmann's discovery has _________(6)
conventional Earth science.
But now scientists are challenging traditional theory with new and radical_________
(7).For example,Earth's center could actually contain an"inner core within the inner
core."claim lshii and colleague Adam Dziewonski.
Analyzing hundreds of thousands of earthquake wave _________(8),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_________(9)from the formation of Earth,"says Dziewonski.
Dziewonski and Ishii speculate that shortly _________(10)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_________(11)mass as the planet
cooled. The core within a core may be the kernel(核心)that endured. " Its presence
could change our basic ideas about the_________(12)of the planet,"Dziewonski
says.
Dziewonski's idea is tame(温和的)compared to the_________( 13 ) theories of
independent geophysicist J. Marvin Herndon.Earth's inner core is made not of iron,he
claims,but a_________(14)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一an
8km-wide ball of the element uranium.Uranium is radioactive.Herndon thinks the uranium
releases heat energy as its atoms_________(15)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.

B.dominated
C.restored

[单项选择]Successful innovations have driven many older technologies to extinction and have resulted in higher productivity, greater consumption of energy, increased demand for raw materials, accelerated flow of materials through the economy and increased quantities of metals and other substances in use per person. The history of industrial development is full of examples.
