Read the following passage and mark the letter A, B, C or D on your answer sheet to indicate the correct answer to each of the following question.
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 century ago, the deep-ocean floor was completely inaccessible, hidden beneath waters averaging over 3,600 meters deep. Totally without light and subjected to intense pressures 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 outer space.
Although researchers have taken samples of deep-ocean rocks and sediments for over a century, the first detailed global investigation of the ocean bottom did not actually start until 1968, with the beginning of the National Science Foundation’s Deep Sea Drilling Project (DSDP). Using 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 frill in very deep waters, extracting samples of sediments and rock from the ocean floor.
The Glomar challenger completed 96 voyages in a 15-year research program that ended in November in 1983. During this time, the vessel logged 600,000 kilometers and took almost 20,000 core samples of seabed sediments and rocks at 624 drilling sites around the word. The Glomar Challenger’s core sample have allowed geologists to reconstruct what the planet looked like hundreds of millions of years ago 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 on the theories of plate tectonics and continental drift that explain many of the geological processes that shape the Earth.
The cores of sediment drilled by the Glomar Challenger have also yielded information critical to understanding the world’s past climates. Deep-ocean sediment provide a climatic record stretching back hundreds of millions of years, because they are largely isolated from the mechanical erosion and the intense chemical and biological activity that rapidly destroy much land-based evidence of past climates. This record had already provided insights into patterns and causes of past climatic change information that may be used to predict future climates
Which of the following is true of the Glomar Challenger?

A. It is a type of submarine

B. It made its first DSDP voyage in 1968

C. It is an ongoing project

D. It has gone on over 100 voyages

Câu 1

On being told about her sack, ………………. .

A. Her boss felt sorry for Mary

B. Marry was shocked

D. all are correct

Lời giải

Đáp án : B

On Ving, S –V = When + S + V, S -V = khi làm gì đó thì điều gì xảy ra. S ở mệnh đề chính phải là chủ thể thực hiện hành động Ving. Being told = được nói (về việc sa thải) -> đối tượng thực hiện là Mary chứ không phải “her boss”, “Mary’s face”
