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 2008to 2012．Some countries have decided to continue these reductions until 2020．More recently，the Paris Agreement，stuck by nearly 200countries，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 2100even 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．
21．It can be concluded from paragraph 1thatD．
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
22．If nations could only keep the initial promises of the Paris Agreement，what would happen by the year 2100？D
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．
23．If those island nations not far above sea level are to survive，the maximum temperature rise，since the start of the industrial age，should beB．
A.0.8℃
B.1.5℃
C.2℃
D.3.5℃
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以及达成目标要符合的条件．
解答 21．D 22．D 23．B
21．D 推理判断题．根据文章第一段三至六句"Since then，many scientists have thought that our actions do make a difference．In 1997，the Kyoto…stuck by nearly 200 countries； also aims to limit global warming．"可知自从 20世纪早期开始人类就一直在努力減少温室气体的排故，希望能减缓全球变暖的趋势．故D项正确．
22．D 推理判断题．根据文章第二段"This is how much temperatures would rise by 2100 even if nations live up to the initial Pans promises to reduce carbon emissions；"可知如果各国的气体排故能够符合巴黎协议的要求，到2100年气温会比现在高三度．而根据第三段"To meet this minimum goal"可知最小的目标是上升两度．也就是说即使各国的气体排砍能够符合巴黎协议的要求，也达不到最小的目标．故D正确．
23．B 细节理解题．根据第四段"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 sinkmg．"可知对于那些低海拔的国家来说温度上升不超过1.5度，就可以避免他们被淹没．故B正确．
点评 做阅读时经常犯错的主要原因是，仅凭读过文章后残留在脑海中的一丝印象来勾选答案，这样便很容易掉入出题人故意设布下的题目陷阱．所谓阅读理解，对于题目的理解一定要忠实于原文，因此，每一道题都应该与原文作全面的对比与核查，再得出答案．也就是说，阅读理解的每一道题目，在原文都应该有明确的出处，我们把这一出处叫做原文相关句，（1）排除与原文相关句主题不一致的选项（2）排除与原文相关句态度相反的选项 （3）排除用于过于极端或负面的选项（4）注意结合文章主旨和主题去排除．
