Question

【題目】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.

【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

【答案】

【1】D

【2】D

【3】B

【解析】

試題分析：本文介紹了人們一直努力減少溫室氣體的排放，并設(shè)立了到2100年我們應(yīng)該達(dá)成的目標(biāo)以及達(dá)成目標(biāo)要符合的條件。

【1】D 推理判斷題。根據(jù)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，自從20世紀(jì)早期開始人類就一直在努力減少溫室氣體的排放，希望能減緩全球變暖的趨勢(shì)。故D項(xiàng)正確。

【2】D 推理判斷題。根據(jù)文章第二段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，如果各國(guó)的氣體排放能夠符合巴黎協(xié)議的要求，到2100年氣溫會(huì)比現(xiàn)在高三度。而根據(jù)第三段2℃右面的內(nèi)容To meet this minimum goal...可知，最小的目標(biāo)是上升兩度。也就是說即使各國(guó)的氣體排放能夠符合巴黎協(xié)議的要求，也達(dá)不到最小的目標(biāo)。故D正確。

【3】B 細(xì)節(jié)理解題。根據(jù)第四段1.5℃右面的內(nèi)容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，對(duì)于那些低海拔的國(guó)家來說最多上升1.5度，他們就可以避免被淹沒。故B正確。
