【分析】
首先通读全文，明确这是一篇介绍风能、风力发电原理及风力发电机发展历史的科普说明文，先把握整体语义逻辑，再逐个结合每个空的上下文语境、对应的语法规则、固定搭配逐一比对选项，排除语法错误、语义不符的干扰项，最终选出正确答案。解题时先判断每个小题对应的考点，再结合知识点验证选项合理性即可。
【解析】
21. 本句语义为“风能能够被用来替代煤炭、石油、天然气等其他能源”，A选项must表“必须”，B选项need to表“需要”，C选项can表“能够、可以”，D选项should表“应该”，只有can符合语境，选C。
22. 此处考察固定搭配be used to do sth，意为“被用来做某事”，句中表示风被广泛用来生产电力，因此用不定式to produce，选B。
23. 句意为“风力发电机是顶部带有3个叶片的高塔”，介词with可表示“带有、具备某种属性”，符合语义，选A。
24. 此处引导时间状语从句，句意为“当风带动叶片转动时，叶片带动机器产出电力”，when表示“当……的时候”符合逻辑，选D。
25. 此处需要副词修饰动词短语turn round，quickly是副词，意为“快速地”，A是形容词、B是形容词比较级、D是名词，均不符合要求，选C。
26. 前文说“这看起来非常简单”，后文说“单个涡轮的动力是不够的”，前后是转折关系，but表转折，选D。
27. 此处泛指一组风力涡轮机，group以辅音音素开头，用不定冠词a，选A。
28. 主语windmills是复数，时间状语more than 1000 years ago表示过去，句子是被动语态，因此be动词用were，选D。
29. 肯定句中表示“也”且放在句中，用also；too和as well通常放在句末，either用于否定句句末，选B。

三、完形填空（每小题1分，满分10分）
I had never imagined studying under bright lights before December 23, 2015.
Changjiang Village in Qinghai Province, the village where I was born, was one of
China's last areas without electricity back then. Without electricity, I had to study
with 31 oil lamps at night. They were not bright enough and hurt my eyes. I
would never forget the terrible smell and dust of burning oil. 32, I could never
study for long.
Everything 33 on that cold winter day. When the power was 34, the
whole village cheered. I 35 at the bright bulb in my home silently for a while,
with tears in my eyes. With electricity, I could study late into the night. My family
bought a second-hand 36 later, and I used it to look up study materials online—
something I'd only dreamed of before.
Life in the village was getting better. The more convenient living environment
gave me a better chance to get an education. I am now at a university where I have
been studying 37 for 2 years. After graduation, maybe I will go back to my
village, become a teacher at the village school, and tell the kids about the changes in
our hometown. Electricity lit up my path, and may it also light up theirs. This is not
just my story. It's how light and 38 came to the last corners of China, changing
39 lives for the better. It's also not just about power—it's about how life gets
better when basic 40 are met.
31. A. electric B. new C. weak D. green
32. A. As a result B. In total C. For example D. By the way

35. A. stared B. met C. watched D. arrived

【分析】
做完形填空首先要通读全文理清故事主线：本文是一篇记叙文，讲述了作者出生在青海偏远无电的村庄，早年只能靠微弱的油灯学习，村庄通电后生活得到极大改善，作者获得了更好的受教育机会，最终感悟到通电这类民生改善给普通人生活带来的积极变化。解题时先跳过空格通读全文把握整体情感和叙事逻辑，之后逐空结合前后文给出的线索、固定搭配、词义辨析来筛选选项，最后把选定的答案代入全文通读，验证逻辑通顺、语义连贯即可：遇到逻辑类的空就判断前后句的因果/顺承关系，遇到名词动词类的空就找上下文对应的提示信息，比如后文提到上网查资料，就能直接对应选出对应的物品。
【解析】
31. 后文明确提到油灯“不够亮还伤眼睛”，说明油灯的光线很微弱。选项A electric（电的）不符合当时村庄无电的背景；B new（新的）原文无相关提示；D green（绿色的）和语境无关，因此选C weak（微弱的）。
32. 前文提到油灯光线差、有难闻的油烟和灰尘，后文“我没法长时间学习”是前文情况带来的结果。A As a result（结果）符合因果逻辑；B In total（总计）、C For example（例如）、D By the way（顺便说）均不符合上下文逻辑，选A。
33. 前文描述无电的艰苦生活，后文描述通电后的便利生活，说明在那个寒冷的冬日一切都发生了改变。A changed（改变）符合语境；B worked（工作）、C ran（运行）、D continued（继续）均不符合文意，选A。
34. 此处指电源被接通、全村通电，D turned on（打开）符合“通电”的常用表达；A put on（穿上/上演）、B focused on（聚焦于）、C listed on（列在……上）均和通电无关，选D。
35. 此处指作者久久凝视着亮起来的灯泡，A stared和介词at构成固定搭配stare at，意为“凝视、盯着看”，符合语境；B met（遇见）、D arrived（到达）代入语义不通，C watched为及物动词，直接接宾语不需要加at表“注视”的含义，因此选A。
36. 后文提到“用它上网查找学习资料”，只有电脑可以实现上网查资料的功能，A computer（电脑）符合提示；B television（电视）、C bulb（灯泡）、D fan（风扇）均无法满足上网查资料的需求，选A。
37. 后文提到作者毕业后打算回村当学校老师，说明作者在大学学习的是教育相关专业，B education（教育）符合语境；A engineering（工程）、C experiments（实验）、D electricity（电力）均和后文当老师的规划不对应，选B。
38. 前文提到电点亮了自己的求学路，也会点亮村里孩子的路，说明此处指光明和希望来到了中国的偏远角落，B hope（希望）符合升华的主题；A plan（计划）、C design（设计）、D honour（荣誉）均不符合语境，选B。
39. 整篇文章讲述的是通电给普通村民的日常生活带来的向好改变，C everyday（日常的）符合文意；A important（重要的）、B special（特殊的）、D wild（野生的）均不符合语境，选C。
40. 此处表达当人们的基本需求得到满足时，生活就会变得更好，basic needs是固定表达，意为“基本需求”，A needs符合搭配和语境；B decision（决定）、C services（服务）、D skills（技能）均不符合语义，选A。
【答案】
31.C 32.A 33.A 34.D 35.A 36.A 37.B 38.B 39.C 40.A
