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.boprah winfrey，the queen of american daytime talk tv，is considered one of the most powerful women in the world.now，after

and experts have proved the uniqueness of fingerprints and discovered that no exactly similar pattern is passed on from parents to children，though nobody knows why this is the case.the ridge(隆起)structure on a persons fingers does not change with growth and is not affected by surface injuries.burns，cuts and other damage to the outer part of the skin will be replaced in time by new one，which bears a reproduction of the original pattern._2_some criminals make use of this fact to remove their own fingerprints but this is a dangerous and rare step to take.fingerprints can be made very easily with printers ink.they can be recorded easily._3_ because of the simplicity and economy of this system，fingerprints have often been used as a method of solving criminal case.a suspected man may deny a charge but this may be in vain._4_when a suspect leaves fingerprints behind at the scene of a crime，they are difficult to detect with the naked eye._5_ some of the marks found are incomplete but identification is possible if a print of a quarter of an inch square can be obtained.aspecial techniques are used to“develop”them.ba fingerprint is an impression of the friction ridges of all part of the finger.cit is only when the inner skin is injured that the arrangement will be destroyed.dwith special methods，identification can be achieved successfully within a short time.ea latent(隐约的)print is the chance reproduction of the friction ridges deposited on the surface of an item.fhis fingerprints can prove who he is even if his appearance has been changed by age or
