Question

【題目】 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】

這是一篇說(shuō)明文。主要說(shuō)明了一項(xiàng)新研究顯示，中國(guó)和印度在改善全球樹木覆蓋方面處于領(lǐng)先地位。同時(shí)中國(guó)和印度占了地球綠化面積的三分之一，但卻只占地球陸地面積的9%�？紤]到人口眾多國(guó)家的土地退化，這是一個(gè)令人驚訝的發(fā)現(xiàn)。

【1】細(xì)節(jié)理解題。根據(jù)第二段中China played a major role, adding 25% to this increase, and India added 6.8%, followed by Canada and Russia.（中國(guó)扮演了主要的角色，增加了25%，印度增加了6.8%，加拿大和俄羅斯緊隨其后。）可知中國(guó)新增的森林面積最大。故選B。

【2】推理判斷題。根據(jù)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.（“過(guò)去20年的綠化表明，植物和樹木的葉子面積增加了，相當(dāng)于整個(gè)亞馬遜雨林的面積，”波士頓大學(xué)研究員、該研究的負(fù)責(zé)人陳馳告訴《自然·可持續(xù)性》雜志。）可知作者提到了亞馬遜雨林，以表明這一成就是多么偉大。故選A。

【3】細(xì)節(jié)理解題。根據(jù)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.（陳馳告訴美國(guó)國(guó)家航空航天局地球觀測(cè)站:“中國(guó)和印度占了地球綠化面積的三分之一，但卻只占地球陸地面積的9%�！保┛芍�B選項(xiàng)“大約9%的地球綠化發(fā)生在中國(guó)和印度”錯(cuò)誤，故選B。
