问题 Choose the correct letter, A, B, C or D.
Write the correct letter in boxes 22-26 on your answer sheet.
In paragraph B, the author intends to

选项 A、show Antarctica has been a central topic of global warming discussion in Mass media.
B、illustrate how its huge sea ice brings food to millions of lives in the world.
C、emphasise the significance of Antarctica to the global climate and ocean currents.
D、illustrate the geographical location of Antarctica as the central spot on Earth.

答案C

解析 题干明确地提出是B段,原文在B段提及“…Antarctica…seen to be an integral part(整体不可分割的部分)of Planet Earth,and a key component in the Earth System”,还有最后一句话“…that Antarctica’s great mass and low temperature exert a major influenceon climate and ocean circulation,factors which influence the lives of millions of people allover the globe”,符合选项C的基本意思。至于选项A中的“global warming”,在B段中并未出现相关信息,所以直接排除A选项。原文B段虽然提及“lives of millionsof people all over the globe”,但是并未提及任何关于“sea ice brings food”的信息,所以排除选项B。最后,选项D“南极洲位于地球的中心”更是不符合事实,可直接排除。综上所述,正确答案为C。
