The ocean bottom--a region nearly 2.5 times greater than the total
land area of the earth--is a vast frontier that even today is largely unexplored
and uncharted. Until about a century ago, the deep-ocean floor
was completely accessible, hidden beneath waters averaging over 3,600 【M1】______.
meters deep. Totally without light and subjected intense pressures 【M2】______.
hundreds of times greater than at the Earth’s surface, the deep-ocean
bottom is a hostile environment to humans, in some ways as forbidding
and remote as the void of out space. 【M3】______.
Therefore researchers have been taking samples of deep-ocean rocks 【M4】______.
and sediments for over a century, the first detailed global investigation of
the ocean bottom did actually start until 1968, with the beginning of the 【M5】______.
National Science Foundation’s Deep Sea Drilling Project (DSDP). Used 【M6】______.
techniques first developed for the offshore oil and gas industry, the
DSDP’s drill ship, the Glomar Challenger, was able to maintain a steady
position on the ocean’s surface and drill very deep waters, extracting【M7】______.
samples of sediments and rock from the ocean floor.
The Glomar Challenger’s core samples have allowed geologists to
reconstruct that the planet looked like hundreds of millions of years ago 【M8】______.
and to calculate what it will probably look like millions of years in the future.
Today largely on the strength of evidence gathered during the Glomar
Challenger’s voyages, nearly all earth scientists agree with the theories【M9】______.
of plate construction and continental drift that explain many of the
geological processes that shape on the Earth. 【M10】______. [br] 【M6】

解析
非谓语动词错误。此处是现在分词短语作伴随状语,因为分冈的逻辑主语是the DSPP’s drill ship,为动作的执行者,所以使用现在分词。
