Question

New genetic analysis has revealed that many Amazon tree species are likely to survive human-made climate warming in the coming century, contrary to previous findings that temperature increases would cause them to die out. A study, 1 in the latest edition of Ecology and Evolution, reveals the 2 age of some Amazonian tree species -- more than 8 million years -- and 3 shows that they have survived previous periods as warm as many of the global warming imagined periods 4 for the year 2100.
The authors write that, having survived warm periods in the past, the trees will 5 survive future warming, provided there are no other major environmental changes. 6 extreme droughts and forest fires will impact Amazonia as temperatures 7, the trees will stand the direct impact of higher temperatures. The authors 8 that as well as reducing greenhouse gas emissions to minimize the risk of drought and fire, conservation policy should remain 9 on preventing deforestation（采伐森林）for agriculture and mining.
The study disagrees with other recent researches which predicted tree species’ extinctions 10 relatively small increases in global average air temperatures.
Study co-author Dr Simon Lewis (UCL Geography) said the 11 were good news for Amazon tree species, but warned that drought and over-exploitation of the forest remained major 12 to the Amazon’s future.
Dr Lewis said: “The past cannot be compared directly with the future. while tree species seem likely to 13 higher air temperatures than today, the Amazon forest is being transformed for agriculture and 14, and what remains is being degraded by logging, and increasingly split up by fields and roads.
“Species will not move as freely in today’s Amazon as they did in previous warm periods, when there was no human 15. Similarly, today’s climate change is extremely fast, making comparisons with slower changes in the past 16.”
“With a clearer 17 of the relative risks to the Amazon forest, we 18 that direct human impacts -- such as forest clearances for agriculture or mining -- should remain a key point of conservation policy. We also need more aggressive 19 to reduce greenhouse gas emissions in order to make minimum the risk of drought and fire impacts and 20 the future of most Amazon tree species.”

試題分析：本文的主要內(nèi)容是，氣候變暖不會(huì)使亞馬遜古代樹種滅絕。
1.C。publish為發(fā)表之意，其他意思不符合。
2.B。一些樹種并未隨氣溫的升高而滅絕，因此超高的樹齡令人驚訝。
3.D。該空所表明的事實(shí)是以前面的樹齡為依據(jù)的，所以是“因此”的意思。
4.C。2100是將來的時(shí)間，預(yù)測(cè)符合意思。
5.B。亞馬遜的樹曾經(jīng)在高溫氣候中生存下來，所以將來也很有可能升高的氣候。
6.B。Although引導(dǎo)讓步狀語。
7.A。氣溫的升高。
8.D。recommend此處是建議的意思，后面的should表明這一層意思。
9.C。防止采伐森林是保護(hù)政策的中心。
10.B。先前的觀點(diǎn)認(rèn)為樹種滅絕是對(duì)相對(duì)小幅氣溫升高的反應(yīng)。
11.A。最新研究的發(fā)現(xiàn)。
12.A。過度采伐威脅亞馬遜的未來。
13.B。耐高溫之意。
14.D。農(nóng)業(yè)和礦業(yè)，A、B與agriculture同一范疇，C毫不相干；最后一段有提示。
15.B。沒有人類影響，物種移動(dòng)更為自由。
16.A。今天的氣溫升高速度遠(yuǎn)遠(yuǎn)快于以前，因此難以與過去相對(duì)比。
17.C。更為清楚的了解亞馬遜森林面臨的風(fēng)險(xiǎn)。
18.B。得出的結(jié)論。
19.D。積極的行動(dòng)和措施。
20.A. 保護(hù)，使…安全。
