27、读】新的基因分析表明：气候变暖不会使亚马孙古代树种灭绝，但直接的人类活动如为农业或采矿的森林清理应该仍然是保护亚马孙森林的关键所在。1Cadvertise做广告；describe描述；publish公布，发表；present呈现。由上文的“A study”以及下文的Ecology and Evolution可知，此处是发表了一项研究。故选C项。2B 由下文“more than 8 million years”可知，亚马孙古代树种的年龄令人吃惊(surprising)。frightening使惊恐的；骇人的；exciting使人兴奋的；interesting有趣的。3D 该空所表明的事实是以前面

28、的树龄为依据的，所以是“因此(therefore)”的意思。4C 正如许多全球变暖设想预测的2100年那样。2100是将来的时间，forecast“预测”符合语境。5B 由上文所述，亚马孙的树种曾经在高温气候中生存下来，所以这里是表示树种以后也可能(probably)在高温下存活。particularly尤其；merely仅仅；possibly也许。6B 由下文“the trees will stand the direct impact of higher temperatures.”可知，设空处与下文为让步关系。although尽管。7Arise升高；change变化；drop掉落，下降；

29、end结束。由上文的“Although”以及后文“the trees will stand the direct impact of higher temperatures”可知，这里说的是气温的升高。故选A项。8D 作者建议，除了减少温室气体排放以最大限度地减少干旱和火灾的风险外，保护政策还应将重点放在阻止为农业和矿业砍伐森林上。表建议，用recommend。9C 由下文“preventing deforestation for agriculture and mining”可知，这里强调的是保护重点应该集中在哪些方面。故选C项。10B 由语境可知，这里说的是树种对于气温小幅度上升的反应(i

30、n response to)。故选B项。11A 这里设空处指代的是前文研究发现，所以是新发现 (findings)。故选A项。12A 由上文的“warned that”可知，干旱和过度砍伐森林对于亚马孙森林的未来是一种威胁(threat)。disadvantage不利条件；embarrassment窘境；instructions用法说明。13B 由语境可知，这里表示树种似乎能忍受(tolerate)更高的温度。故选B项。14D 由下文“and what remains is being degraded by logging,and increasingly split up by field

31、s and roads.”可知，亚马孙森林正在向农业和矿业(mining)转变。故选D项。15B 由上文的“freely”可知，没有人类影响(influence)，物种移动更为自由。16A 今天的气温升高速度远远快于以前，因此很难(difficult)与过去相对比。clear清楚的；easy简单的；important重要的。17C由语境可知，此处意为了解(understanding)亚马孙森林面临的风险。18B 由语境可知，通过上文对亚马孙森林的相对风险的了解，我们从而得出结论(conclude)。19D 由下文“to reduce greenhouse gas emissions”可知，这里

32、是需要行动(action)。20A 由上文“to reduce greenhouse gas emissions in order to make the risk of drought and fire impacts minimum”可推知，减少温室气体的排放，减少干旱和火灾的风险是为了保护(secure)亚马孙树种的未来。advance提前；sacrifice牺牲；evaluate评估。.语法填空阅读下面材料，在空白处填入适当的内容(1个单词)或括号内单词的正确形式。Chinas agriculture produces enough food supply to feed the co
