B级 能力素养提升练 Ⅳ.阅读理解 (2026四川广安前锋区高二上期中) In the mid-19th century,a simple operation could often be a death sentence.Even if a patient survived the surgeon’s knife,they frequently fell victim to deadly infections afterwards.Hospitals were filled with the smell of decay(腐烂),and surgeons saw infection as an unavoidable part of surgery. Joseph Lister,a British surgeon,was deeply troubled by the high death rates from post-surgical infections.He refused to accept that they were unavoidable.While studying wound inflammation,he learned about the work of Louis Pasteur,who proposed that germs(tiny,invisible organisms) caused decay and disease.This was a revolutionary idea at the time. Lister made a brilliant connection.He reasoned that if germs in the air were causing wounds to decay,then the solution was to kill these germs before they could enter the wound.He began experimenting with carbolic acid,a chemical used to treat waste water.He developed a system where he would spray a fine mist of carbolic acid in the air around the operating area,clean surgical tools with it,and soak wound dressings in it.The results were dramatic.The death rate from infection following his surgeries plummeted. Despite his success,Lister faced significant resistance from the medical community.Many senior surgeons believed that Lister was accusing them of being dirty.They were unwilling to change their old ways.However,Lister persisted,patiently publishing his findings and demonstrating his methods. Gradually,as other surgeons adopted his antiseptic techniques,the evidence became undeniable.Surgery was transformed.Lister’s principles of killing germs to prevent infection laid the foundation for modern antiseptic surgery.His work,built on Pasteur’s germ theory,saved countless lives and forever changed the course of medicine,turning surgery from a dreaded last resort into a safe,life-saving practice. 1.What was the common belief about infections in surgery before Lister’s time? A.They were caused by dirty surgical tools. B.They were an unavoidable part of surgery. C.They could be easily treated with chemicals. D.They only happened in unclean hospitals. 2.What was the key idea from Louis Pasteur that inspired Lister? A.The importance of washing hands. B.The use of carbolic acid for cleaning. C.The germ theory of disease. D.The method of spraying chemicals in the air. 3.What does the underlined word “plummeted” in paragraph 3 mean? A.Increased slightly.　　 B.Remained stable. C.Rose dramatically. D.Fell sharply. 4.What is the most appropriate title for the passage? A.The Discovery of Germ Theory B.The Life Story of a Great Surgeon C.The Use of Carbolic Acid in Medicine D.The Man Who Conquered Surgical Infection Ⅴ.完形填空 “Would you say you are more of a scientist or an artist?” I always　1　 this question,particularly after I told my scientific peers (同行) that I’m 　2　 writing poetry.And I learned to 　3　,“A scientist” — not because it was necessarily 　4　,but because I sensed it would win me more 　5　 and honor from others.

Ⅳ.【语篇解读】本文是一篇记叙文。文章讲述了19世纪中期手术感染致死率极高,英国外科医生李斯特受巴斯德细菌理论启发,发明了杀菌方法,显著降低了感染死亡率,推动了现代无菌手术的诞生。 1.B　细节理解题。根据第一段中的“Hospitals were filled with the smell of decay,and surgeons saw infection as an unavoidable part of surgery.”可知,在约瑟夫·李斯特发明杀菌方法之前,外科医生认为感染是手术不可避免的一部分。故选B项。 2.C　细节理解题。根据第二段中的“While studying wound inflammation,he learned about the work of Louis Pasteur,who proposed that germs(tiny,invisible organisms) caused decay and disease.”和第三段中的“Lister made a brilliant connection.He reasoned that if germs in the air were causing wounds to decay,then the solution was to kill these germs before they could enter the wound.”可知,巴斯德提出的细菌会导致腐烂和疾病这一理论给了李斯特启发。故选C项。 3.D　词句猜测题。根据画线词前文“He developed a system where he would spray a fine mist of carbolic acid in the air around the operating area,clean surgical tools with it,and soak wound dressings in it.The results were dramatic.”可知,使用了他的杀菌方法,结果非常显著,由此可推测,感染致死率应该是显著下降了,plummet意为“暴跌”,与D项“剧烈下降”意思一致。故选D项。 4.D　主旨大意题。全文围绕李斯特如何研究并推广杀菌技术、从而攻克手术感染展开,突出了他对医学的革命性贡献。D 项最能概括主题。故选D项。 Ⅴ.【语篇解读】本文是一篇记叙文。文章主要讲述了作者在面对自己身为科学家和艺术家的双重身份时的内心挣扎,以及最终接受并欣赏自己双重身份的过程。 1.B　根据下文“after I told my scientific peers”以及最后一段的“Now if the question is addressed to me about whether I’m more of a scientist or an artist,I’ll say,‘Both.’”可知,作者经常听到这个问题。 2.D　be cautious about对……小心谨慎;be capable of能够;be serious about对……是认真的;be fond of喜欢。根据下文“After that,I wrote poems secretly,”以及全文内容可知,作者喜欢写诗。 3.A　根据上文“‘Would you say you are more of a scientist or an artist?’ I always 　　　this question”可知,别人经常问这个问题;而根据空后“A scientist”可知,作者回复说自己更像个科学家。  4.C　根据下文“but because I sensed it would win me more 　　　and honor from others.”可知,作者这样回复,不是因为这是真的而是认为这样得到的荣誉更多。  5.D　根据下文的“honor from others”可知,空处和“honor”意思相近,“尊重”符合语境。 6.B　根据下文“peers might interpret the love for art as a 　　　of passion for science.”以及上文作者偷偷写诗可知,作者担心别人认为自己对科学不够投入。  7.D　根据下文的“My heart began to race.”以及上文作者偷偷写诗可知,当这个毕业生这样和作者说的时候,作者惊呆了。 8.C　根据上文“So,when a graduate whispered ‘I hear you write poetry!’ in my ear in the lab,I 　　　.My heart began to race.”可知,尽管作者偷偷写诗,还是有人知道作者在写诗。此处指的是作者的心理活动,作者在想是不是自己的伪装暴露了。  9.A　根据上文“After that,I wrote poems secretly,worried about being seen as less 　　　to science than others.”可知,作者不想让别人知道自己在写诗,所以听到这个人的邀约,作者挣扎了几天。  10.C　根据下文“The night of the party,I was amazed at the talent on display.”可知,作者最终出现在聚会上。 11.D　根据下文“I learned many shared my 　　　:peers might interpret the love for art as a 　　　of passion for science.”可推测,这些都是作者和别人聊天才了解的内容。  12.A　根据上文“After that,I wrote poems secretly,worried about being seen as less 　　　to science than others.”以及下文“peers might interpret the love for art as a 　　　of passion for science.”可知,这些都是担忧。  13.B　根据上文“After that,I wrote poems secretly,worried about being seen as less 　　　to science than others.”可知,人们总是认为喜欢艺术的人对科学不够投入,也就是缺乏热情。  14.D　根据下文“Now if the question is addressed to me about whether I’m more of a scientist or an artist,I’ll say,‘Both.’”可知,作者已经接受了自己的两种身份,既是艺术家也是科学家。 15.B　根据下文“Now if the question is addressed to me about whether I’m more of a scientist or an artist,I’ll say,‘Both.’”中的“Both”可知,作者已经接受了真正的自我。 知识积累卡
