Question

【题目】 China and India are leaders in improving global(全球的) tree cover, a new study based on NASA research showed.

They took a 31.8% part together of the total global new leaf area between 2000 and 2017. China played a major role, adding 25% to this increase, and India added 6.8%, followed by Canada and Russia. The study in the Nature Sustainability journal shows that more than 5.5 million square kilometers of green leaf area was added globally. Since 2000, there has been a five-percent increase in global green cover, it said.

“The greening over the last twenty years shows an increase in leaf area on plants and trees which is as large as the area of the entire Amazon rainforest," Chi Chen, a Boston University researcher and lead of the study told Nature Sustainability. Large plantation activities to protect forests in China contributed nearly 42% to the country's green cover, and agriculture added another 32%. In India, 82% of the increase in leaf area was because of agriculture.

“China and India take up one-third of the greening, but hold only nine percent of the planet's land area covered in green plants," Chi Chen told NASA Earth Observatory. “That is a surprising finding, considering the land degradation(退化) in countries with large populations.”

Boston University's research team first detected an increase in global green cover in the 1990s but were unsure about what contributed to the increase. Finally, with the help of NASA's Terra and Aqua satellites research, they managed to find out the increase in leaf cover from different areas and places.

【1】Which country increased the largest part of the new leaf area?

A.IndiaB.China

C.CanadaD.Russia

【2】For what purpose did the author mention the Amazon rainforest?

A.To show how great the achievement was.

B.To show the importance of rainforest.

C.To explain what difficulties we have now.

D.To explain the reason for increasing forests.

【3】According to paragraph four, the following statements are true EXCEPT_______.

A.China and India have large populations and land degradation problem

B.about 9% of the planet’s greening is in China and India

C.China and India are leading in the global green cover increase

D.the leaf cover area in China and India is still limited if viewed globally

Answer 1

【答案】

【1】B

【2】A

【3】B

【解析】

这是一篇说明文。主要说明了一项新研究显示，中国和印度在改善全球树木覆盖方面处于领先地位。同时中国和印度占了地球绿化面积的三分之一，但却只占地球陆地面积的9%。考虑到人口众多国家的土地退化，这是一个令人惊讶的发现。

【1】细节理解题。根据第二段中China played a major role, adding 25% to this increase, and India added 6.8%, followed by Canada and Russia.（中国扮演了主要的角色，增加了25%，印度增加了6.8%，加拿大和俄罗斯紧随其后。）可知中国新增的森林面积最大。故选B。

【2】推理判断题。根据第三段中“The greening over the last twenty years shows an increase in leaf area on plants and trees which is as large as the area of the entire Amazon rainforest," Chi Chen, a Boston University researcher and lead of the study told Nature Sustainability.（“过去20年的绿化表明，植物和树木的叶子面积增加了，相当于整个亚马逊雨林的面积，”波士顿大学研究员、该研究的负责人陈驰告诉《自然·可持续性》杂志。）可知作者提到了亚马逊雨林，以表明这一成就是多么伟大。故选A。

【3】细节理解题。根据第四段中“China and India take up one-third of the greening, but hold only nine percent of the planet's land area covered in green plants," Chi Chen told NASA Earth Observatory.（陈驰告诉美国国家航空航天局地球观测站:“中国和印度占了地球绿化面积的三分之一，但却只占地球陆地面积的9%。”）可知B选项“大约9%的地球绿化发生在中国和印度”错误，故选B。
