Question

Is there link between humans and climate change or not? This question was first studied in the early 1900s. Since then, many scientists have thought that our actions do make a difference. In 1997, the Kyoto Protocol explained our role in the Earth’s changing atmosphere and set international limits for gas emissions(排放) from 2008 to 2012. Some countries have decided to continue these reductions until 2020. More recently, the Paris Agreement, stuck by nearly 200 countries, also aims to limit global warming. But just now how much warmer it will get depends on how deeply countries cut carbon emissions.

3.5℃

This is how much temperatures would rise by 2100 even if nations live up to the initial Paris promises to reduce carbon emissions; this rise could still put coastal cities under water and drive over half of all species to extinction.

2℃

To meet this minimum goal, the Agreement requires countries to tighten emissions targets every five years. Even this increase could sink some islands, worse drought(干旱) and drive a decline of up to a third in the number of species.

1.5℃

This is the most ambitious goal for temperature rise set by the Paris Agreement, after a push by low-lying island nations like Kiribati, which say limiting temperature rise to 1.5℃ could save them from sinking.

0.8℃

This is how much temperatures have risen since the industrial age began, putting us 40% of the way to the 2℃ point.

0℃

The baseline here is average global temperature before the start of the industrial age.

1.It can be concluded from paragraph 1 that _______.

A. the problem of global warming will have been quite solved by 2020

B. gas emissions have been effectively reduced in developed countries

C. the Paris Agreements is more influential than the Kyoto Protocol

D. humans have made continuous efforts to slow down global warming

2.If nations could only keep the initial promises of the Paris Agreement, what would happen by the year 2100?

A. The human population would increase by one third.

B. Little over 50% of all species would still exist.

C. Nations would not need to tighten their emissions targets.

D. The Agreement’s minimum goal would not be reached.

3.If those island nations not far above sea level are to survive, the maximum temperature rise, since the start of the industrial age, should be _______.

A. 0.8℃B. 1.5℃C. 2℃D. 3.5℃

Answer

1.D

2.D

3.B

【解析】

试题分析：本文介绍了人们一直努力减少温室气体的排放，并设立了到2100年我们应该达成的目标及达成目标需要符合的条件，但现实情况是达不到。

1. 推理判断题。根据第一段Since then, many scientists have thought that our actions do make a difference. In 1997, the Kyoto Protocol explained our role in the Earth’s changing atmosphere and set international limits for gas emissions(排放) from 2008 to 2012. Some countries have decided to continue these reductions until 2020. More recently, the Paris Agreement, stuck by nearly 200 countries, also aims to limit global warming.可知，从20世纪早期开始人类就一直努力减少温室气体的排放，希望能减缓全球变暖的趋势，故选D。

2. 推理判断题。根据第二段This is how much temperatures would rise by 2100 even if nations live up to the initial Paris promises to reduce carbon emissions;可知，如果各国的气体排放能符合巴黎协会的要求，到2100年气温会比现在高三度。而根据第三段To meet this minimum goal可知，最小目标是上升两度，也就是说即使各国气体排放能够符合要求也达不到最小目标，故选D。

3.中This is the most ambitious goal for temperature rise set by the Paris Agreement, after a push by low-lying island nations like Kiribati, which say limiting temperature rise to 1.5℃ could save them from sinking.可知，对于那些低海拔的国家来说温度上升不超过1.5度，就可以避免被淹没。故选B。

考点：考查环保类短文阅读。

【名师点睛】

在做阅读理解题过程中，应首先略读一下短文，了解一下短文的大致意思，然后把题干看明白知道里面的关键词，把几个选项含义理解透，尤其注意意思相近，表达有交叉的选项之间的区别。然后再细读短文，找到根据，把答案填入合适位置。答题时可以把含义相近的几个选项轮流填入同一处位置，反复阅读，反复体会，找出最佳选项。不同的题型采用不同的做题方法和技巧，完成短文后，再认真通读一遍全文，看看上下语意是否通顺，是否符合逻辑关系。

另外，做题时要注意文章的首段和每一段的首句或尾句，它们往往就是文章的主题句。阅读中要注意要点之间的关系，弄清全文的结构也能帮助我们理解文章，做出正确答案。
