B
In Antarctica (南极洲), about 12.3 million km² of its area are covered with ice. At present, this continent holds about 26.5 million km² of ice. However, nearly one-fifth of the total Antarctic ice sheet (冰盖) surface had experienced observable melting (融化) during the past two decades (十年), according to a report released by China’s MOST this year. Also, it is predicted that the melting conditions of the Antarctic ice sheet will continue to increase and will be almost impossible to reverse (逆转), even if global emissions reduction goals are reached.
Climate change and extreme weather may cause the melting in this world’s southernmost (最南端 的) continent and may have significant influences — from changing animals’ living places to increasing global sea levels. If all that ice melts, it would raise the global sea level by 58.3 meters — enough to submerge thousands of cities in the near future. The ice is melting so fast that it would also have a great influence on animals living on this icy continent.
According to another research published in Nature, over the past 40,000 years, ice sheets thousands of kilometers away have influenced one another through sea level changes, and the changes in the Antarctic ice sheet were driven by the melting ice sheets in Northern Hemisphere. This study shows how interconnected the Earth system is.
We mankind is a community of shared future. Without doubts, in the history of the human pursuit (追求) of economic development, the world has faced many challenges, like the melting in Antarctica mentioned above. Only when all countries work together to care for our environment while developing can the challenges be overcome in the end.
41．About of Antarctic ice sheet surface had melted over the past twenty years.
A．2.46 million km². B．5.3 million km². C．12.3 million km². D．26.5 million km².
42．What does the underlined word “submerge” in Paragraph 2 probably mean in Chinese?
A．冰冻 B．淹没 C．合并 D．建造
43．Which of the following can best describe the writer’s opinion in the last paragraph?
A．One piece of firewood does not make high flames.
B．It was the best of times; it was the worst of times.
C．All things are difficult before they are easy.
D．A long journey can be covered only by taking one step at a time.
44．What can be inferred from the text?
A．We have to give up the pursuit of economic development.
B．The melting ice was caused by the increasing global sea levels.
C．The changes in one part of the Earth system will influence another.
D．If global emissions are reduced, the melting ice sheet can come back.
45．What would be the best title for the text?
A．Animals’ Lost Homeland B．Increasing Global Sea Levels
C．Climate Changes on Earth D．Melting Ice Sheets in Antarctica

【导语】
本文是一篇说明文，介绍南极冰盖融化的情况。
41．推理判断题。根据“At present, this continent holds about 26.5 million km² of ice. However, nearly one- fifth of the total Antarctic ice sheet surface had experienced observable melting during the past two decades, according to a report released by China's MOST this year.”可知，目前，这片大陆上约有2650万平方公里的冰，然而根据中国科技部今年发布的一份报告，近五分之一的南极冰盖表面在过去20年里经历了可观测到的融化。所以在过去20年中，大约有530（2650×1/5=530） 万平方公里的南极冰盖融化，故选B。
42．词义猜测题。根据“If all that ice melts, it would raise the global sea level by 58.3 meters-enough to submerge thousands of cities in the near future.”可知，如果所有的冰都融化了，全球海平面将上升58.3米——在不久的将来足以淹没数千座城市。所以此处submerge的意思是“淹没”，故选B。
43．推理判断题。根据“We mankind is a community of shared future. Without doubts, in the history of the human pursuitof economic development, the world has faced many challenges, like the melting in Antarctica mentioned above. Only when all countries work together to care for our environment while developing can the challenges be overcome in the end.”可知，本段作者想表达的是我们人类单个的力量是薄弱的，我们需要共同努力使环境变得更好，因此选项A“一块柴烧不出高火”符合，故选A。
44．推理判断题。根据“According to another research published in Nature, over the past 40,000 years, ice sheets thousands of kilometers away have influenced one another through sea level changes, and the changes in the Antarctic ice sheet were driven by the melting ice sheets in Northern Hemisphere. This study shows how interconnected the Earth system is.”可知，数千公里外的冰原通过海平面变化相互影响，而南极冰原的变化是由北半球冰原融化造成的，这项研究显示了地球系统是如何相互联系的。由此可知，地球系统一部分的变化将影响另一部分，故选C。
45．最佳标题题。本文主要介绍南极冰盖融化的情况，选项D“南极洲冰盖融化”符合主题，故选D。

61．例文
Hello, everyone!
          I’m Li Hua, a student from No.1 High School. Today I’d like to share my opinions on “Build green and beautiful hometown together”.
As middle school students, it’s our duty to help build a green and beautiful hometown. First, we can ride bikes or walk to school if it’s not far away from our homes. The more people choose the public transportation, the fewer traffic jams there will be and the cleaner the air will be. Second, we mustn’t throw rubbish here and there. We must throw them into the dustbin. If so, our hometown will be clean and tidy. We will feel more comforable, too. Third, plant more trees. Trees are important to the environment. They can make the air much fresher.
We should do everything we can to protect the environment.
