题目与答案

1. 14 With the investigation of the lake, scientist may predict the climate changes in the future.
   • TRUE
   • FALSE
   • NOT GIVEN

   答案：TRUE

   原文定位：the lake holds an untapped reservoir of information that could help scientists predict future climate changes by looking at evidence from the past

   同义替换：「With the investigation」↔「using state-of-the-art equipment to help unlock the mysteries」

2. 15 The crater resulted from a meteorite impact is the largest and most preserved one in the world.
   • TRUE
   • FALSE
   • NOT GIVEN

   答案：FALSE

   原文定位：The resulting crater is one of the largest an most well-preserved geologically young craters in the world

3. 16 The water stored in Lake Bosumtwi was gone only by seeping through the lake sediments.
   • TRUE
   • FALSE
   • NOT GIVEN

   答案：FALSE

   原文定位：but the water leaves only by evaporation, or by seeping through the lake sediments

   同义替换：「was gone only by seeping through the lake sediments」↔「evaporation, or by seeping」

4. 17 Historical climate changes can be detected by the analysis of the sediment in the lake.
   • TRUE
   • FALSE
   • NOT GIVEN

   答案：TRUE

   原文定位：For the past million years, the lake has acted as a tropical rain gauge, filling and drying with changes in precipitation and the tropical climate. The record of those changes is hidden in sediment below the lake bottom

   同义替换：「Historical」↔「past million years」，「can be detected by」↔「hidden in」

5. 18 The greatest obstacle to research of scientists had been the interference by the locals due to their indigenous believes.
   • TRUE
   • FALSE
   • NOT GIVEN

   答案：NOT GIVEN

   原文定位：Problems that arose were primarily non-scientific-tree stumps, fishing nets, cultural barriers, and occasional misunderstandings with local villagers

6. a 19_____ is needed to create the explosion into the water

   答案：air gun|high-pressure air gun

   原文定位：In this process, a high-pressure air gun is used to create small, pneumatic explosions in the water

   同义替换：「is needed」↔「is used to」

7. The 20_____ enters deep into the water and return back

   答案：sound energy

   原文定位：The sound energy penetrates about 1,000 to 2,000 meters into the lake’s subsurface before bouncing back to the surface of the water

   同义替换：「enters deep into」↔「penetrates」，「return back」↔「bouncing back」

8. a 50-meter 21_____ with many 22_____ embeded

   答案：cable|||hydrophones|underwater microphones

   原文定位：embedded in a 50-meter long cable that is towed behind the boat;The reflected sound energy is detected by underwater microphones-called hydrophones embedded in a 50-meter long cable

9. The boat-double R/V Kilindi crossed the lake was dismantled and stored in a 23_____ .

   答案：shipping container

   原文定位：It was constructed in modules that were dismantled, packed inside a shipping container, and reassembled

   同义替换：「stored in」↔「packed inside」

10. The technology they used called 24_____;they created sound energy in to 1000-2000 metres in to the bottom of the lake, and separated equipment to collect the returned waves.

    答案：seismic reflection profiling

    原文定位：returned to Abono to begin collecting data about the lake’s subsurface using a technique called seismic reflection profiling

11. Then the data had been analyzed and processed in the 25_____ .

    答案：laboratory

    原文定位：On-board computers record the signals, and the resulting data are then processed and analyzed in the laboratory

12. Scholz also added that they were now building 26_____ view of the sediment or sub-image in the bottom of the lake.

    答案：three-dimensional

    原文定位：we are now developing three-dimensional perspective of the lake’s subsurface and the layers of sediment that have been laid down

    同义替换：「building」↔「developing」，「view」↔「perspective」

13. Whole set of equipment works well yet the ship should avoid physical barrier including tree stumps or 27_____ floating on the surface on the lake.

    答案：fishing nets

    原文定位：Problems that arose were primarily non-scientific-tree stumps, fishing nets, cultural barriers, and occasional misunderstandings with local villagers

    同义替换：「physical barrier including tree stumps or」↔「non-scientific-tree stumps, fishing nets」
