【题目】 Record fires sweeping across the Amazon recently have been making the headlines as scientists and environmental groups are worried that they will worsen climate change crisis and endanger biodiversity(生物多样性）。
As the largest rainforest in the world, the Amazon is often called"the lungs of the world”. It is also home to about 3 million species of plants and animals, and 1 million local people. The vast area of rainforest plays an important role in the world's ecosystem because it absorbs heat instead of reflecting heat back into the atmosphere. It also stores carbon dioxide and produces oxygen, ensuring that less carbon is released, reducing the effects of climate change.
＂Any forest destroyed is a danger to biodiversity and the people who use that biodiversity," Thomas Lovejoy, an ecologist at George Mason University told National Geographic."The great danger is that a lot of carbon goes into the atmosphere,"he stressed."In the midst of the global climate crisis, we cannot afford more damage to a major source of oxygen and biodiversity.The Amazon must be protected,"UN Secretary General Antonio Guterres said.
Data from the National Institute for Space Research(INPE)show that the number of forest fires in Brazil quickly increased by 82 percent from January to August a year ago.A total of 71,497 forest fires were registered in the country in the first 8 months of 2019,up from 39,194 in the same period in 2018,INPE said.＂We estimate that the forest areas in the Brazilian Amazon have decreased something between 20 and 30 percent compared to the last 12 months," Carlos Nobre, a researcher at the University of Sao Paulo, told German broadcaster Deutsche Welle.
Brazil owns about 60 percent of the Amazon rainforest,whose degradation(恶化）could have severe consequences for global climate and rainfall.The extent of the area ruined by fires has yet to be determined, but the emergency has gone beyond Brazil's borders.
【1】What is the second paragraph mainly about?
A.The great role of the Amazon rainforest.
B.The effects of consistent climate change.
C.The causes of the decreasing biodiversity.
D.The results of the Amazon rainforest fires.
【2】Why does the author mention the figures in the fourth paragraph?
A.To explain the process of the research.
B.To present the bad influence of forest fires.
C.To prove the great importance of the rainforest.
D.To show the emergency of protecting the rainforest.
【3】What does the author want to tell us in the passage?
A.The dry weather leads to the rainforest fires.
B.The biodiversity makes the rainforest unique.
C.The rainforest fires result in serious consequences.
D.The global climate crisis brings more rainforest fires.
【4】Which section of a magazine might this passage probably be taken from?
A.Climate and life.
B.Nature and geography.
C.Humankind and society.
D.Science and technology.
【答案】
【1】A
【2】D
【3】C
【4】B
【解析】
本文是一篇说明文。文章主要介绍了雨林火灾造成严重的后果以及保护亚马逊雨林的紧急性。
【1】主旨大意题。根据第二段第三句“The vast area of rainforest plays an important role in the world's ecosystem because it absorbs heat instead of reflecting heat back into the atmosphere.”可知，广袤的雨林在世界生态系统中扮演着重要的角色，因为它吸收热量，而不是将热量反射回大气。再结合第二段内容可知，第二段主要讲亚马逊雨林的巨大作用。故选A项。
【2】推理判断题。根据第四段中的“We estimate that the forest areas in the Brazilian Amazon have decreased something between 20 and 30 percent compared to the last 12 months”可知，Carlos Nobre说：“我们估计巴西亚马逊河流域的森林面积比过去12个月减少了20%到30%”。再根据第三段最后一句中的“The Amazon must be protected”可推知，作者提到第四段中的数字是为了说明保护雨林的紧急性。故选D项。
【3】主旨大意题。根据全文内容尤其最后一段“Brazil owns about 60 percent of the Amazon rainforest, whose degradation(恶化）could have severe consequences for global climate and rainfall. The extent of the area ruined by fires has yet to be determined, but the emergency has gone beyond Brazil's borders.”可知，巴西拥有大约60%的亚马逊雨林，其恶化可能对全球气候和降雨的后果严重。火灾毁坏的地区范围尚未确定，但紧急情况已经超出了巴西的边界。由此可推知，作者旨在告诉我们，雨林火灾造成严重的后果。故选C项。
【4】推理判断题。根据第一段中的“they will worsen climate change crisis and endanger biodiversity”和第二段中的“The vast area of rainforest plays an important role in the world's ecosystem”并结合全文内容可知，本文讲述的是关于自然和地理的知识，所以本文最有可能摘自报纸的自然地理部分。故选B项。
