B主旨大意题。文章第一段给出了海洋颜色变化的原因,第二段具 体说明了海洋颜色变化的原因在于海洋浮游植物的类型和浓度的变 化。综上所述,前两段主要说明了海洋颜色变化的原因，故选B项。2 . A词义猜测题。根据下文气候变暖改变了海洋的主要特点,影响了

12、浮游植物的生长,结合关键词changes和affect可综合推断出浮游植 物对海洋变暖的趋势是比较敏感的,故选A项（敏感的）。B:有益的;C: 重大的;D:不被注意的。3 .D推理判断题。根据第四段中Butinsomewaters. . . awarmingwillmakeconditionsriperforphytopl ankton, andtheseareaswi 11 turngreener.可知，在更适宜浮游植物生 长的地方,海洋的颜色会变得更绿,故选D项（有更多浮游植物的海洋 可能看上去更绿）。4 .C推理判断题。根据全文，尤其是中心段落第一段中theworld，soceanswi

13、llbebluerandgreenerthankstoawarmingclimat e可知,文章的主要目的是解释气候变化对海洋尤其是其颜色的影响, 故选C项。A项（评估海洋颜色变化产生的后果）、B项（分析海洋食物 链的构成）和D项（介绍一种研究浮游植物的新方法）均不符合文章目 的,故排除。长难句分析原句Whentheseorganismsdie, theyburycarboninthedeepocean, animport antprocessthathelpstoregulatetheglobalclimate.分析本句为主从复合句。句子的主干为theyburycarbono thathelpstoregulatetheglobalclimate 为定语从句，先行词为processo句意当这些微生物死亡时,它们将碳埋在深海中，这是一个有助于调 节全球气候的重要过程。
