题目与答案

1. 1 Research trawls in the deepest oceans tend to produce important findings.
   • TRUE
   • FALSE
   • NOT GIVEN

   答案：TRUE

   原文定位：In fact, the deepest parts of the ocean are so poorly known that nearly every submarine dive or research trawl (pulling up specimens from the seabed) brings new knowledge of genuine significance to oceanographers

2. ·10 The Chatham Rise is considered a good place for _____ by local people.

   答案：fishing

   原文定位：They come fishing here because a valuable species called orange roughy seasonally migrates to these shallow waters to spawn

3. Canyons

   ·11 The presence of whales in Goose Bay has resulted in the development of _____ .

   答案：tourism

   原文定位：and every year thousands of people come to see the whales just off the coast, helping local tourism

4. ·12 A species of _____ has been discovered near Dunedin.

   答案：coral

   原文定位：Among these was a population of button-sized coral, whose remains had originally been mistaken by early fossil collectors for small dinosaur bones

5. ·Most New Zealand canyons were created by a strong current caused by a river on the coast nearby.

   ·13 One canyon near Canada was formed when a big _____ started a current in 1929.

   答案：earthquake

   原文定位：when a significant earthquake in Canadian waters triggered an underwater current that travelled more than 720 kilometres, creating a canyon

6. 2 In New Zealand, research into land biodiversity is better understood than ocean research.
   • TRUE
   • FALSE
   • NOT GIVEN

   答案：TRUE

   原文定位：Our present knowledge of land biodiversity (all animal and plant life) compared with ocean biodiversity is one measure of how early we are in the task of researching the deep sea

7. 3 The takahe bird was first recorded as a species in 1948.
   • TRUE
   • FALSE
   • NOT GIVEN

   答案：FALSE

   原文定位：In 1948, a small population of takahe, a flightless bird which at that time was thought to be extinct, was found living in New Zealand’s mountains

8. 4 Museums only display a small number of their specimens from the deep ocean.
   • TRUE
   • FALSE
   • NOT GIVEN

   答案：NOT GIVEN

   原文定位：Just because an animal has been given a scientific name and shelf space in a museum doesn’t necessarily mean that we know anything at all about its lifestyle and ecology

9. 5 Filming specimens gives accurate information about the normal behaviour of their species.
   • TRUE
   • FALSE
   • NOT GIVEN

   答案：FALSE

   原文定位：Most deep-sea animals have never been seen alive, and the few that have were almost certainly acting unnaturally in the glare of lights from the submarine camera with which they were observed

    • TRUE
    • FALSE
    • NOT GIVEN

11. 7 The approach used by deep-sea biologists is similar to that used in police investigations.
    • TRUE
    • FALSE
    • NOT GIVEN

    答案：TRUE

    原文定位：In some respects, deep-sea biology parallels the way that detectives hunt for criminals, requiring comparable problem-solving and clue-finding skills

12. **The sea floor around New Zealand

    Seamounts**

    ·The exact number of seamounts is not known.

    ·8 The Bollons Seamount is unusual because of its _____ .

    答案：size

    原文定位：It rises more than three kilometres above the surrounding seabed, and measures two hundred kilometres across, making it a remarkable size, and therefore of particular interest

13. ·9 Seamounts are home to many species, perhaps because there is more food and less _____.

    答案：mud

    原文定位：Another factor is that they are not completely draped with the fine mud that covers just about everything else in the deep sea
