答案以及解析

【夯實基礎】

【核心素養(yǎng)】

A

答案：1-4BABC

解析：1.主旨大意題。根據第二段第一句"Asthelargestrainforestintheworld，theAmazonisoftencalled'thelungsoftheEarth'."可知，本段主要介紹了亞馬孫雨林的重要作用，故選B項。由第二段最后一句可知，亞馬孫雨林的存在會減輕氣候變化的影響，但與A項"氣候變化的影響"不是同一層面的概念，故不選。C項"亞馬孫雨林火災的影響"以及D項"生物多樣性減少的原因"在第二段均未提及。

2.詞義猜測題。根據畫線詞所在的第二段最后一句"Theyalsostorecarbondioxide(二氧化碳)andproduceoxygen，makingsurethatlesscarbonisgivenoff，mitigatingtheeffectsofclimatechange."可推知，畫線詞mitigating意為"減輕"，ease"減輕，緩解"，故選A項。B項"引起，導致"，C項"惡化"和D項"有益于"均不符合題意。

3.推理判斷題。根據第三段中"Anydestructionofforestsisathreattobiodiversityandthepeoplewhousethatbiodiversity"及"Theshockingthreatisthatalotofcarbongoesintotheatmosphere,"hestressed."Facingtheglobalclimatechange，wecannotaffordmoredamagetoamajor
