Question

【題目】 The world is a greener place than it was 20 years ago. Recent NASA satellites data(2000—2017) have shown that human activities in China and India dominate this greening of the planet, thanks to ambitious tree-planting programmes in China and intensive agriculture(集約農(nóng)業(yè)) in both countries.

The researchers from Boston University found that global green leaf area has increased by 5 percent in the new century, an area equal to all of the Amazon rainforest. China alone accounts for 25% of the global net increase in leaf area with only 6.6% of global vegetated area. China's contribution comes in large part from its programmes to conserve and expand forests, taking up about 42 percent of the greening. The greening from farmlands in China is about 32%, but that in India is about 82%.

Rama Nemani, a research scientist at NASA's Ames Research Centre and a co-author of the study said, 'When the greening of the Earth was first observed, we thought it was due to a warmer, wetter climate and fertilisation from the added carbon dioxide in the atmosphere. But with data from NASA satellites, scientists realised that humans are also contributing, which was all against our expectations. '

Nemani sees a positive message in the new findings. 'Once people realise there is a problem, they tend to fix it, ' he said. 'In the 1970s and 1980s in India and China, the situation around vegetation loss was not good. In the 1990s, people realised it, and today things have improved. Humans are incredibly resilient. That is what we see in the satellite data. '

However, the researchers rang bells as well. They said that the gain in global greenness did not necessarily make up for the loss of natural vegetation in regions like Brazil and Indonesia.

【1】What is the second paragraph mainly about?

A.The decreasing size of the Amazon rainforest.

B.China's bigger contribution to global greening.

C.Total global green leaf area in the new century.

D.China's programmes to conserve and expand forests.

【2】What surprised scientists regarding global greening?

A.Human activities.B.The level of fertilisation.

C.A warmer and wetter climate.D.Carbon dioxide in the atmosphere.

【3】What does the underlined word 'resilient' probably mean?

A.Good at making programmes.B.Suitable for analysing data.

C.Able to make corrections.D.Active in planting trees.

【4】What does the last paragraph imply?

A.It is urgent to protect global natural resources.

B.Much remains to be done for global greenness.

C.Brazil and Indonesia lose most of their vegetation.

D.Global greenness needs all countries to work together.

Answer 1

【答案】

【1】B

【2】A

【3】C

【4】B

【解析】

這是一篇新聞報道。據(jù)研究報道，印度和中國正在引領(lǐng)全球的綠色行動，讓地球變綠。作者建議人類應(yīng)該好好利用耕地，保護環(huán)境。

【1】主旨大意題。根據(jù)本段的主要內(nèi)容，尤其是China alone accounts for 25% of the global net increase in leaf area with only 6.6% of global vegetated area. China's contribution comes in large part from its programmes to conserve and expand forests, taking up about 42 percent of the greening. The greening from farmlands in China is about 32%,(僅中國就占全球葉綠面積凈增長的25%，，占全球植被面積的6.6%。中國的主要貢獻來自于起保護和擴大森林的計劃，約占綠化的42%。中國的農(nóng)田綠化率約為32%)可知，第二段主要說明了中國對全球綠化的突出貢獻。B. China's bigger contribution to global greening.(中國對去求綠化的巨大貢獻)符合以上說法，故選B項。

【2】細節(jié)理解題。根據(jù)第三段中的But with data from NASA satellites, scientists realised that humans are also contributing, which was all against our expectations.可知，通過NASA衛(wèi)星的數(shù)據(jù)，科學家意識到人類活動也會有助于全球綠化，這出乎科學家們的意料。即讓科學家家驚訝的是人類活動也有助于全球綠化。A. Human activities.(人類活動)符合以上說法，故選A項。

【3】詞義猜測題。根據(jù)最后一段的'Once people realise there is a problem, they tend to fix it, ' he said. 'In the 1970s and 1980s in India and China, the situation around vegetation loss was not good.In the 1990s, people realised it, and today things have improved. Humans are incredibly resilient. '可知，一旦人們意識到問題，他們往往會去解決它。在20世紀70年代和80年代中國和印度的植被情況不太好。在20世紀90年代人們意識到了這個問題，而現(xiàn)在情況有了好轉(zhuǎn)，人類是非常resilient。結(jié)合句意可知，當人們意識到問題時，會迅速做出了調(diào)整來解決問題，故推測劃線部分的意思是“做出調(diào)整/糾正問題”。C. Able to make corrections.(能夠改正錯誤)符合以上猜測，故選C項。

【4】推理判斷題。根據(jù)最后一段However, the researchers rang bells as well. They said that the gain in global greenness did not necessarily make up for the loss of natural vegetation in regions like Brazil and Indonesia.(但是，科學家也敲響了警鐘。他們說，全球綠化面積的增加并沒有彌補巴西和印度尼西亞減少的自然植被)可推測，對于全球綠化，人類做得還遠遠不夠。B. Much remains to be done for global greenness.(全球綠化還有很多工作要做)符合以上推測，故選B項。
