Question

Researchers in over 80 nations are taking part in a project to conduct a decade-long census(统计) of sea life. Scientists presented some of their findings at a recent conference as the project neared its completion.
In deep icy waters under Antarctica, scientists found bulbous tunicates, an underground animal, and many newly-discovered creatures believed to be related to starfish (海星) and other marine(海洋的）creatures.
Elsewhere in the world’s oceans, they have recently discovered many kinds of underwater life forms new to science. It is all part of a research effort called the Census of Marine Life.
“There are about 2,000 scientists worldwide involved,” said Bob Gagosian, President, CEO of the Consortium for Ocean Leadership. Gagosian helps manage the project. “Everywhere they’ve gone they’ve found new things,” he says. “The ocean basically is unexplored from the point of view of marine living things.”
Researchers have placed small markers on hundreds of fish and marine animals to track by satellite their migration(迁移）routes and to discover places where sea life gathers.
According to Ron O’Dor, a senior scientist with the Census of Marine Life, knowledge of life on the ocean floor is especially limited. “90% of all the information we have is from the top hundred meters of the ocean,” O’Dor states.
And he says the sea floor is, on average, at a depth of 4, 000 meters. And so, as some machines dive far below what people have previously seen, scientists are discovering new species of plants, animals and living things.
Since the census project began, more than 5,300 new marine animals have been found. Ocean researchers say they hope to catalogue 230,000 species during the census —which some say is only a small part of all the creatures living in the sea.

1. 1.
   Why do the researchers place small markers on many marine creatures?
   1. A.
      To catch them.
   2. B.
      To research them.
   3. C.
      To kill them.
   4. D.
      To protect them.
2. 2.
   From what Ron O’Dor says, we can conclude that        .
   1. A.
      human beings only know a little about marine life
   2. B.
      the oceans don’t need to be further explored
   3. C.
      he considers exploring the ocean a dangerous thing
   4. D.
      the marine creatures mainly live on the top of the ocean
3. 3.
   What can we learn from the passage?
   1. A.
      About 2,000 scientists from America are involved in the project.
   2. B.
      The census of sea life will last for ten years.
   3. C.
      230,000 new marine animals have been found.
   4. D.
      The sea floor is at a depth of 400 meters.
4. 4.
   Why does the author write the passage?
   1. A.
      To tell the news that new marine creatures are being discovered
   2. B.
      To encourage people to find new marine creatures
   3. C.
      To prove the importance of marine creatures
   4. D.
      To introduce the newly-discovered creatures.

Answer 1

BABA
文章主要对一项研究进行介绍，告诉读者发现了很多深海生物，人类对于海洋的认识还很少。
1.事实细节题，根据第五段Researchers have placed small markers on hundreds of fish and marine animals to track by satellite their migration(迁移）routes and to discover places where sea life gathers可知，是为了研究他们。
2.推理判断题，根据The ocean basically is unexplored from the point of view of marine living things可以，人类对于海洋的认识还是非常非常少的。
3.事实细节题，根据第一段Researchers in over 80 nations are taking part in a project to conduct a decade-long census(统计) of sea life可知，这是一项长达十年的研究。
4.主旨大意题，文章主要对一项研究进行介绍，告诉读者发现了很多深海生物。
