19． The world's oceans are slowly getting more acidic． say scientists．The researchers from Californi——青夏教育精英家教网——

19．"The world's oceans are slowly getting more acidic．"say scientists．The researchers from California report that the change is taking place in response to higher levels of carbon dioxide in the atmosphere．
         The lowering of the waters'PH value is not great at the moment but could cause a serious threat to current ocean life if it continues，they warn．Ken Caldeira and Michael Wickett，from the Lawrence Livermore National Laboratory，report their concerns in the journal Nature．Increasing use of oil fuels means more carbon dioxide is going into the air，and most of it will eventually be absorbed by seawater．Once in the water，it reacts to form carbonic acid．Scientists believe that the oceans have already become slightly more acidic over the last century．
         These researchers have tried to predict what will happen in the future by combining what we know about the history of the oceans with computer models of climate change．"This level of acidity will get much more extreme in the future if we continue releasing CO2 into the atmosphere，"said Dr Caldeira．And we predict the amount of future acidity will exceed（超过） anything we have seen over the last several hundred million years，let alone perhaps after rare disastrous events such as asteroid（小行星） impacts
          However，it is not absolutely clear what that means for ocean life．Most organisms live near the surface，where the greatest PH change would be expected to occur，but deep-ocean life forms may be more sensitive to PH changes．Coral reefs（珊瑚礁） and other organisms whose shells contain calcium carbonate（碳酸钙） may be particularly affected if the water's acidity levels keep going up，the team predict．They could find it much more difficult to build these structures in water with a lower PH．
         In recent years some people have suggested storing carbon dioxide from power station in the deep ocean as a way of dealing with global warming．But Dr Caldeira said that such a strategy should now be re-considered．"Previously，most experts had looked at ocean absorption of carbon dioxide as a good thing--because in releasing CO2 into the atmosphere we warm the planet，and when CO2 is absorbed by the ocean，it reduces the amount of greenhouse warming．"
57．The ocean is becoming more acidic due toC．
A．the lower water PH value
B．the warming atmosphere
C．the higher level of CO2 in the air

18．The most detailed breakdown（分析） of ethnic and gender performance in national curriculum tests for 7，11 and 14-year-olds shows that Chinese pupils do best in every subject at every age．Chinese and Indian pupils outperformed white British children in English tests for 11-year-olds．In all，83% of Chinese students reached the required standard compared with 78% of Indian pupils and 75% of white UK pupils and only 65% of Bangladeshi children reaching level four，the standard that an 11-year-old should achieve．
         While the overall results show the performance of every ethnic group at GCSE（中等教育普通证书） is improving，they do highlight a worrying trend for white British pupils．David Miliband，the minister for School Standards，said the results showed that while standards in secondary schools were rising，there was"a shocking gender gap between boys and girls"．He added："58.2% of girls achieved five A to C grade passes at GCSE in 2003 compared with just 49.9% of boys，and white working-class boys are one of the lowest performing groups at 14．"According to researchers，"In the weeks leading up to GCSE unsupervised study leave at home in many areas has become the norm（惯例）．They are left to their own devices．"Mr．Miliband is supporting a plan to persuade schools to drop study leave before GCSEs and replace it with structured revision in school．
