题文
The hole in the Earth's ozone layer (臭氧层)has until now protected Antarctica from the worst effectsof 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 3C 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 connected-Antarctica may be a long way away but it is an important part of
the Earth's system," said Johnson. "It contains 90% of the world's ice, 70% of the world's fresh water
and that is enough, if it melts completely,to raise sea levels by 63 metres. "
Even in a worsecase situation scientists don't 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. 1. The underlined word "paradoxically" (in Paragraph 2) most probably means "________". A. rapidly
B. approximately
C. contradictorily

考点
据考高分专家说，试题“ The hole in the .....”主要考查你对 [健康环保类阅读 ]考点的理解。健康环保类阅读
健康环保累阅读概念：
健康环保类文章常是介绍科学知识、生活常识和环境保护方面的短文。体裁有记叙文、 说明文、议论文和各种应用文。
健康环保类文章阅读技巧：
健康环保类文章常是介绍科学知识、生活常识和环境保护方面的短文。阅读此类短文要以现象或事物为中心进行思考，理解现象产生的原因、条件和客观规律等。同时要抓住事物的特征、用途和相互关系等。科普环保类文章一般为说明文，从结构上看大致可分为三个部分：
第一部分一般是文章的首段，主要用来提出文章的主题，即文章想要阐述、说明的主要内容；
第二部分是文章的主体，可由若干个段落组成，对文章的主题进行展开说明；
第三部分是结尾段，对文章的主题进行归纳总结。这类文章多用一般现在时，而且一般多使用客观性词语表述。有时为了强调客观性，也常使用被动语态。
从近几年的考试题来看，科普环保类的文章越来越与人们的实际生活相接近。由于此类文章缺乏故事情节，很多同学对此类文章感到费解。但一般的科普类文章都是就事论事，需要逻辑推理和想象的时候较少，因此此类阅读题也没有同学们想象中的那么难，只要多加训练，就能较好地答题。
