课时知能训练.阅读理解(2012广东潮州月考)the hole in the earths ozone layer (臭氧层)has until now protected antarctica from the worst effects of global warming.but scientists have warned that as the hole closes up in the next few decades，temperatures on the continent could rise by around 3 on average，with melting ice contributing to a global sea level increase of up to 1.4 metres.in the past decades the western antarctic has seen rapid ice loss as the world has warmed，but the other parts of the continent have，paradoxically，been cooling，resulting in a 10% increase in ice in the seas around the region.this is because the hole in the ozone layer has increased cold winds in antarctica，making much of the continent surface colder than usual.but now that the gasses that cause the ozone hole have been banned，scientists expect the hole to repair itself within the next 50 to 60 years.by then the cooling effect will have faded out and the antarctic will face the full impact of global warming.this means an increase in average air temperatures of around 3 and a reduction in sea ice by around a third.the biggest threat to the continent comes from warming seas.robert johnson，a scientist who monitors antarctica ice sheets，said，“the ice sheets in antarctica are hundreds of metres thick.but once warm ocean waters start flowing underneath，the ice will begin thinning and could break up very quickly.” thinning ice sheets cause ice to break away from the continent and to melt even faster.escaping ice from western antarctica has already resulted in a 10% rise in global sea level in recent decades.johnson believes that international action to reduce global warming is required immediately or it may be too late.“everything is connectedantarctica may be a long way away but it is an important part of the earths system，” said johnson.“it contains 90% of the worlds ice,70% of the worlds fresh water and that is enough，if it melts completely，to raise sea levels by 63 metres.”even in a worsecase situation scientists dont expect the ice to entirely disappear，but predict that，because of the melting ice sheets，average sea level rise will be around 1.4 metres higher by the end of the century.【语篇解读】本文主要描述了由于臭氧层的破坏，南极洲冰层正处于加速融化的危险中。科学家认为南极冰层不会完全消失，但海平面会随着冰层的融化而上升。1the underlined word “paradoxically” (in paragraph 2) most probably means “_”arapidlybapproximatelyccontradictorily dapparently【解析】词义猜测题。首先，选项词义要牢记；其次，划线词所在句中的but为推断关键，划线词应理解为相反地。【答案】c2what is the effect of the hole in the ozone layer on antarctica?ait is making much of the continent colder.bit is causing the ice to melt faster.cit is making the effects of global warming in the region worse. dit is reducing the amount of water in antarctica.【解析】细节理解题。从第二段最后一句“this is because the hole in the ozone layer has increased cold winds in antarctica，making much of the continent surface colder than usual.”可以得出答案。【答案】a3what do scientists think is the biggest danger facing antarctica?arising sea levels.bwarming sea water temperature.cwater pollution.dgrowing ice sheets.【解析】细节理解题。从第四段第一句“the biggest threat to the continent comes from warming seas.”可得出答案。the biggest threat对应the biggest danger。【答案】b4which of the following is true according to the passage?aantarctica contains most of the worlds fresh water.bthe average temperature has increased by 3 degree centigrade in recent decades.cantarctica is currently experiencing the full effects of global warming.dten percent of antarcticas ice has already been lost.【解析】细节理解题。(或通过常识亦可判断)，从第五段最后一句“it contains 90% of the worlds ice,70% of the worlds fresh water.”可得出答案。【答案】a5the best title for the passage is _.aour planet in dangerbantarctica melting awaycaction plan to save antarcticadlets save the ozone layer【解析】标题确定题。先排除a，然后文中未提及任何挽救南极的措施同时未提到呼吁保护臭氧洞，排除c、d两项。全文论述的是南极洲正处于融化的危险之中，故选b。【答案】b.信息匹配下面是一篇应用文及其应用场合的信息，请阅读下列应用文和相关信息，并按照要求匹配信息。首先请阅读下列应用文：asales manager requirements：minimum of 2year sales experience；university/college degree；good command of english；excellent communication skills；responsible，patient，energetic，enthusiastic；customer service，teaching experience is preferred；basic office computer skills (excel，word，email)bproject management assistant requirements：good english and computer skills；related working experience is a must；patient，careful，supportive；strong team spirit.cenglish teacher requirements：university degree or above in english major；eager to learn and openminded with creativity；with deep understanding and respect for different cultures.dmarketing assistant requirements：college degree or above with good english (speaking and writing) skills；with basic ideas of sales and marketing；working experience is not necessary；good communication and presentation skills.eaccountant requirements：college degree or above in finance (金融学) area；good english and computer skills；good sense of finance management；at least two years of experience as an accountant in an international organization is a must;
