unit 19 b卷一、阅读理解athe climate secrets of the deepest part of the ocean，the marianas trench(壕沟)in the western pacific ocean，have been explored by scientists.the international team used a submersible，designed to withstand great pressure，to study the bottom of the 10.9kmdeep underwater canyon.their early results reveal that ocean trenches are acting as carbon sinks.this suggests that they play a larger role in regulating the earths chemistry and climate than was thought.although two explorers，jacques piccard and don walsh，reached the deepest part of the marianas trencha point called the challenger deepin 1960，no humans have been back since.and the scientific missions，including this recent visit to this deepest spot，have been carried out using unmanned underwater vehicles.lead researcher professor ronnie glud，from the university of southern denmark and the scottish association for marine science，said that working at more than 1,000 atmospheres of pressure was challenging，but advances in technology had made it possible.he told bbc news，“this is the first time we have been able to set down sophisticated(精密的)instruments at these depths to measure how much carbon is buried there.”the tests also helped the scientists to assess the storage of carbon at those dark depths.this is not the first time deep sea trenches have surprised scientists.recent studies by university of aberdeens oceanlab team have revealed that marine life is much more abundant in this difficult habitat than was previously thought.in 2008，they filmed the deepest living fish ever to be caught on cameraa 17strong shoal(鱼群)found at depths of 7.7km in the japan trench，and they discovered that other animals such as amphipods were present in large numbers even deeper.dr alan jamieson，from oceanlab，said the new study was helping researchers to build up a better idea of what happens in the deepest of the deep.1from the description of carbon sinks we learn that _.athey have been on the ocean floor for thousands of yearsbthe trenches can be used to control climatecthere are many chemistry resources on the ocean floordthe carbon sinks contribute to changes in the climate2what can be inferred from the passage?amany scientists have died in the marianas trench during explorations.bjacques piccard and don walsh came back successfully from the marianas trench.cunmanned underwater vehicles have replaced humans in exploring the floor since 1960.dthe explorations of the trench have not been launched until 1960.3what do we know from ronnie gluds words?ahumans cant work at more than 1,000 atmospheres of pressure.bthe research aimed to assess the carbon storage at those dark depths.ccarbon is the most important mineral resource on the ocean floor.dfinding out the storage of carbon is one of the main tasks of scientists.4the last paragraph is mainly about _.athe surprising findings of marine lifebthe bad environment of marine lifecthe
