life and freedom.athe；ab/；thecthe；the da；a解析：考查冠词的用法。当world前有形容词修饰时，常与不定冠词连用，表示“一个的世界”；第二个空a place作前面a.world的同位语。答案：d2it was a matter of _ would take the position.awho bwhoevercwhom dwhomever解析：句意：那是一个谁当选的问题。who would take the position在句中作介词of的宾语。答案：a3he forgot the work his manager had told；_，he was scolded severely by the manager and fined heavily.aluckily bhoweverctherefore dbesides解析：考查副词辨析。前后两个分句之间是因果关系，所以应该用表示因果关系的副词therefore。luckily“幸运地”；however“然而”；besides“除此之外(还有)”，均不符合语境。答案：c4he must have finished the work by the end of last month，_ he?amustnt bhadntcdidnt dhasnt解析：主句的时间状语by the end of last month是过去完成时的时间状语，因此b项符合。答案：b5he is so good a teacher in this school _ is loved by almost all the students.athat bwhichcthan das6do you think our basketball players played very well in the last match?yes._.athey are not nervous at allbthey couldnt have done bettercthey played naturallydthey were still young解析：考查比较级表示最高级的用法。此处they couldnt have done better.是一句赞扬的话。说明他们已经尽了最大努力，不会打得比这再好了。这是最好的。答案：b7we should try every effort to prevent violence from happening at school，_ more and more students would drop out of school _ their personal safety could not be guaranteed.afor；now that bfor；ifcthough；so long as dthough；if only解析：考查连词。第一个空用for，表原因；第二个空用if，表条件。句意：我们必须竭尽全力阻止校园暴力的发生，因为如果人身安全得不到保障，就会有越来越多的学生辍学。答案：b8what we can see there is _ remained of the city after the strong earthquake.a/ bthatcwhat dit解析：考查名词性从句。sth.remained of“所剩下的东西”。what引导的是表语从句，在从句中what作remained of的主语。句意：我们所能看到的那边的东西是大地震过后所剩下的东西。答案：c9he went up the stage with his head _ high.aheld bholdingcrisen draising解析：在with n.的复合结构中，用过去分词表示被动。hold ones head high“高昂着头”。句意：他高昂着头走上了舞台。答案：a10oh，dear，youre back home at last!you cant imagine all the difficulty i had _ home in the heavy rain.awalked bwalkcto walk dwalking解析：考查固定搭配。have difficulty in doing sth.“干某事很困难”。答案：d11it remains _ whether the patient can survive the major operation or not.ato observe bto be

knowledge；only _thinking can we make _ we read ours.aby；it bwith；thatcthrough；anything dby；what解析：第一个空考查only介词短语作状语放于句首引起倒装的用法；第二个空考查what引导的名词性从句，what在宾语从句中作read的宾语，ours作宾语的补足语。答案：d14the government must do more _ pollution _ more happily.ato prevent；from living bto stop；livingcto prevent；to live dto keep；living解析：第一个空是do something 后跟不定式表示“采取措施干某事”；第二个空是不定式短语作目的状语，不要看成是prevent.from doing结构。此题易错选a项。答案：c15the door burst open and _.the room soon became crowded.ain rushed the children bin did the children rushcin the children rushed drushed in the children解析：考查倒装。在一些副词如 out，in，off，down，up等开头的句子中，如果主语是名词，句子用完全倒装语序。答案：a二、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.马里亚纳海沟是太平洋的最深处，它在地球气候变化中起着非常重要的作用。科学家最近对它进行了探索。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 climate解析：推理判断题。根据第二段this suggests that they play a larger role in regulating the earths

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.解析：推理判断题。根据第五段this is the first time.to measure how much carbon is buried
