( First:glance through the questions )
An annoying problem for humans, who
like to boast (夸耀) about all the distant
planets and moons we have explored, is
that we've never taken a good look right
under our noses. The inside of the earth is
relatively close, but how can we get there?
The deepest oil well enters a mere six
miles into the crust (地壳) (the center of
the earth is about 4,000 miles deeper).
Russian scientists dug the deepest hole in
Siberia, but bottomed out at about 7.5
miles below the surface. The Mohole
project, a U.S. plan in the 1950s, called for
drilling a hole 25 miles down to the
boundary between the hard rocks of the
crust and the soft mantle (地幔). Sadly the
project involved government supporting.
• It gets harder and harder to drill deep into
the earth because rocks get softer and
softer. Hard but easily broken at the
surface, rocks become plastic at depth,
and the pressure caused by the weight of
the overlaying crust --- about 52,800
pounds per square inch at a depth of ten
miles, makes further drilling impossible.
• Scientist David Stevenson says we should forget
about drilling holes. Instead, we should open a
crack (裂缝).
Stevenson suggests digging a crack about a half
mile long, a yard wide, and a half mile deep (not
with a shovel) but with an explosion on the scale
of a nuclear bomb. Next, he'd pour a few
hundred thousand tons of molten (熔化的) iron
into the crack, along with a robot. The iron,
thicker than the surrounding crust, would move
downward at about 16 feet per second, carrying
the robot with it and opening the crack deeper
and deeper. The iron mass would drop for about
a week and 2,000 miles to the outer edge of the
earth core, the robot sending out data to the
surface.
• Stevenson compares his idea to space
exploration. "We're going somewhere we
haven't been before,"he says. "In all
possibility, there will be surprises.”
This idea can probably be put in the
drawer marked with Isn't Going To Happen.
The robot would have to survive
temperatures that would melt pretty much
anything. But Stevenson's idea may
inspire a new look at an old problem.

Stevenson's idea?

use now.
• C. It is a good proposal that will soon be put
into practice.
• D. It is a false theory that cannot be carried out
at all.
