2020·全国卷Ⅲ·阅读理解D篇
We are the products of evolution, and not just evolution that occurred billions of years ago. As scientists look deeper into our genes (基因), they are finding examples of human evolution in just the past few thousand years. People in Ethiopian highlands have adapted to living at high altitudes. Cattle-raising people in East Africa and northern Europe have gained a mutation (突变) that helps them digest milk as adults.
On Thursday in an article published in Cell, a team of researchers reported a new kind of adaptation — not to air or to food, but to the ocean. A group of sea-dwelling people in Southeast Asia have evolved into better divers. The Bajau, as these people are known, number in the hundreds of thousands in Indonesia, Malaysia and the Philippines. They have traditionally lived on houseboats; in recent times, they've also built houses on stilts (支柱) in coastal waters. “They are simply a stranger to the land，” said Rodney C．Jubilado, a University of Hawaii researcher who studies the Bajau.
Dr. Jubilado first met the Bajau while growing up on Samal Island in the Philippines. They made a living as divers, spearfishing or harvesting shellfish. “We were so amazed that they could stay underwater much longer than us local islanders，” Dr. Jubilado said. “I could see them actually walking under the sea.”
In 2015, Melissa Ilardo, then a graduate student in genetics at the University of Copenhagen, heard about the Bajau. She wondered if centuries of diving could have led to the evolution of physical characteristics that made the task easier for them. “It seemed like the perfect chance for natural selection to act on a population，” said Dr. Ilardo. She also said there were likely a number of other genes that help the Bajau dive.

思维建模 模型应用
第一步：速读 结合主题段、主题句抓文章大意 通读全文可知，文章主要介绍了研究发现居住在东南亚的巴瑶族人为了更好地生存，进化成了更好的潜水者。
第二步：确认 文章大意关键词或概括性强或情感强烈或出现频率高的关键词 第二段中提到为了适应海洋，东南亚的一群海洋居民已经进化成更好的潜水者。结合文章最后一段中提到的“几个世纪的潜水是否导致了身体特征的进化，使他们更容易完成任务。”可确定关键词 “adaptation，evolve，ocean”。
第三步：概括 结合行文逻辑概括全文信息得出标题 本文主要讲述了巴瑶族人为了更好地适应海上的生活，身体结构发生了变化，所以“为了海上生活而重塑身体”适合作本文的标题。故选A。

三、寻结构破长句

试翻译：东非和北欧的养牛人获得了一种 的突变。

四、赏佳句助写作
1．(赏结构之美)She wondered if centuries of diving could have led to the evolution of physical characteristics that made the task easier for them.
赏析：作者用一个常见句式She wondered if ... (她想弄明白是否……)描述了研究基因的Melissa Ilardo对巴瑶族人是否为了更好地生存，进化成了更好的潜水者这一现象的兴趣。if引导宾语从句，从句中的定语从句that made the task easier for them，运用了“make＋宾语＋宾语补足语”的结构。整个句子结构紧凑，表意清晰。
[对点练——完成句子]
① you'd be kind enough to give us some information.
我想知道是否你能足够友好，给我们一些信息。
②We must to the public that something should be done to stop pollution.
我们必须使公众明白应该做一些事情来制止污染。

make it clear
2．(赏用词之美)“It seemed like the perfect chance for natural selection to act on a population，” said Dr. Ilardo.
赏析：句中seem(好像，似乎)表示其后内容为推断，like体现了推断的客观性；形容词perfect(完美的)修饰名词chance，表现了对这个机会的重视；动词短语act on(对……起作用)不落俗套，体现了说明的严谨性。整个句子用词恰当严谨，表意客观准确。
3．(赏意境之美)They made a living as divers, spearfishing or harvesting shellfish.
赏析：as divers描述了巴瑶族人的身份，现在分词短语spearfishing or harvesting shellfish作状语，描写了他们的生活常态。句子虽着墨不多，但却生动形象地描绘了一个不为太多人了解、可以在水下停留较长时间、用鱼叉捕鱼或收获贝类为生的族群，引发了读者丰富的想象。
