  Tsung-Dao Lee, a Chinese American physicist who shared the Nobel Prize in Physics in 1957 for overturning what had been considered a fundamental law of nature—that particles (粒子) are always symmetrical (对称的)—died on Sunday at his home in San Francisco. He was 97.
The theory that Dr. Lee overturned was called the law of conservation (守恒) of parity (宇称), which said that every phenomenon and its mirror image should behave precisely the same. At the time he challenged the theory, in 1956, it had been widely accepted for 30 years. Dr. Lee was then a young professor at Columbia, where he had been promoted to full professor at age 29—the youngest in the university’s history at that point.
In 1956, Dr. Lee and Dr. Chen Ning Yang published their theory in the journal Physical Review. A groundbreaking experiment by the physicist Chien-Shiung Wu involving the decay of cobalt (钴) atoms was performed later that year, confirming that Dr. Lee and Dr. Yang were right. They were awarded the Nobel Prize the following year. Dr. Lee was just 31 when he accepted the prize; he and Dr. Yang were the first Chinese-born laureates (诺贝尔奖得主).
Dr. Lee had an exceptionally long and productive career. He retired from regular teaching at Columbia in 2012, at age 86, but continued to contribute ideas to particle physics research into his 90s.
Dr. Lee remained fairly modest about the discovery that brought him the Nobel Prize. It was the product of insight about something that, it turned out, was hiding in plain sight. “Nobody saw it before because it was a mental block,” he said in the 2007 interview. “Nobody looked for it.”
1.What does the underlined word “overturned” mean in paragraph 2
A. Considered acceptable. B. Proved wrong.
C. Criticized heavily. D. Backed by experiments.
2.Why is the physicist Chien-Shiung Wu mentioned in paragraph 3
A. To praise her achievement. B. To share her experiment.
C. To present experimental basis. D. To prove Lee’s brilliance.
3.Which of the following words can best describe Dr. Lee
A. Ambitious and productive. B. Intelligent and courageous.
C. Influential and cautious. D. Humble and exceptional.
4.What is the text
A. A biography. B. An encyclopedia. C. A brochure. D. A journal.

  In the race to document the species on Earth before they go extinct, researchers and citizen scientists have collected billions of records. Today, most records of biodiversity are often in the form of photos, videos, and other digital records. Though they are useful for detecting shifts in the number and variety of species in an area, a new Stanford study has found that this type of record is not perfect.
“With the rise of technology it is easy for people to make observations of different species with the aid of a mobile application,” said Barnabas Daru, who is lead author of the study and assistant professor of biology in the Stanford School of Humanities and Sciences. “These observations now outnumber the primary data that comes from physical specimens (标本), and since we are increasingly using observational data to investigate how species are responding to global change, I wanted to know: Are they usable ”
Using a global dataset of 1.9 billion records of plants, insects, birds, and animals, Daru and his team tested how well these data represent actual global biodiversity patterns.
“We were particularly interested in exploring the aspects of sampling that tend to bias (使有偏差) data, like the greater likelihood of a citizen scientist to take a picture of a flowering plant instead of the grass right next to it,” said Daru.
  Their study revealed that the large number of observation-only records did not lead to better global coverage. Moreover, these data are biased and favor certain regions, time periods, and species. This makes sense because the people who get observational biodiversity data on mobile devices are often citizen scientists recording their encounters with species in areas nearby. These data are also biased toward certain species with attractive or eye-catching features.
  What can we do with the imperfect datasets of biodiversity
“Quite a lot,” Daru explained. “Biodiversity apps can use our study results to inform users of oversampled areas and lead them to places—and even species—that are not well-sampled. To improve the quality of observational data, biodiversity apps can also encourage users to have an expert confirm the identification of their uploaded image.”
5.What do we know about the records of species collected now
A. They are becoming outdated. B. They are mostly in electronic form.
C. They are limited in number. D. They are used for public exhibition.
6.What does Daru’s study focus on
A. Threatened species. B. Physical specimens.
C. Observational data. D. Mobile applications.
7.What has led to the biases according to the study
A. Mistakes in data analysis. B. Poor quality of uploaded pictures.
C. Improper way of sampling. D. Unreliable data collection devices.
8.What is Daru’s suggestion for biodiversity apps
A. Review data from certain areas. B. Hire experts to check the records.
C. Confirm the identity of the users. D. Give guidance to citizen scientists.

A 首位华人诺贝尔奖得主李政道逝世,97年传奇人生落幕。当地时间2024年8月4日凌晨,著名华人物理学家李政道在美国旧金山家中去世,享年97周岁。1956年,他和杨振宁一起研究出了弱相互作用中“宇称不守恒定律”,并在次年凭此发现共同获得诺贝尔物理学奖。
1.B 词句猜测题。由下文提到的“he challenged the theory (他质疑这一理论)”和构词(turn over 翻身;翻转—overturn)可猜测出, overturn 意为“推翻;颠覆”,故与proved wrong 同义。
2.C 写作意图题。第三段介绍了吴健雄的实验,证明了李政道和杨振宁理论的正确性,故提出她是为了提供实验依据,故C项正确。
3.D 推理判断题。文章介绍李政道是首位华人诺贝尔奖得主,且获奖时仅31岁,由此说明他是杰出的;文章最后一段又提到“Dr. Lee remained fairly modest”可知,他是谦虚的,故D项正确。
4.A 推理判断题。文章介绍了首位华人诺贝尔奖得主李政道逝世,其取得的成就等,由此可知,本文属于传记,故A项正确。

重点词 overturn vt.把……掀翻;把……结论/定论推翻
语块 ①a law of nature自然界客观存在的规律,自然法则 ②in plain sight显眼的 ③full professor正教授
背景 知识 宇称不守恒定律(Nonconservation of Parity)是指:在弱相互作用中,互为镜像的物质的运动不对称,由吴健雄用钴60验证。所谓宇称,就是镜像。在1956年以前,科学界一直认为“宇称守恒”,也就是说,一个粒子的镜像与其本身性质完全相同。
B 斯坦福大学的一项研究发现,数字生物多样性记录存在偏差,本文仔细剖析了这些电子记录不靠谱的原因并提出了弥补方案。
5.B 细节理解题。根据第一段中的“Today, most records of biodiversity are often in the form of photos, videos, and other digital records. (现在大多数生物多样性的记录都是以照片、视频和其他电子形式存在的)”可知,现在收集的物种记录大多是以电子形式存在的。故选B。
6.C 推理判断题。第二段提出人们越来越多地使用观测数据研究物种如何应对全球变化,并提出疑问:这些观察数据可用吗 又由第三段中的“tested how well these data represent actual global biodiversity patterns (测试这些数据在多大程度上代表实际的全球生物多样性模式)”,可知, Daru的研究重点是“观察数据”。故选 C。
7.C 推理判断题。本题需概括第四段和第五段的内容,第四段提到Daru的研究团队在探索网民们取样方面的偏差,比如网民们会因为花比草更加显眼而拍花,而不是拍草。第五段的内容进一步拓展说明该要点,第五段第二句说明这些数据偏向于某些区域、时段和物种, 最后一句说明这些采集的数据会更加偏向引人注目的某些物种。由此可知, 民间科学家的采样可能不合适,从而导致收集到的数据产生偏差。故选C。
8.D 隐含推断题。根据最后一段可知,Daru 认为 biodiversity apps 可以根据研究结果引导采样人员关注样本采集不足的地区和物种,鼓励他们让专家确认上传样本图片中的物种名称。因此,Daru 建议 biodiversity apps 提供给采样人员一些指导意见。have an expert confirm和give guidance to citizen scientists属于同义转述

4.individuals 考查名词的数。空处作主语,空前是some,故可数名词individual 应用复数形式,填individuals。
5.how 考查名词性从。 5  mosquitoes find food作understand的宾语, 破折号后的内容解释的是蚊子觅食的方式,故宾语从句中缺少方式状语,表“如何”,应用how引导宾语从句。
6.a 考查冠词。此处指“一种帮助孵卵的方式”,故用不定冠词,means是辅音音素开始的单词,故填冠词a。
7.remarkably 考查词形转换。空处作状语,修饰形容词good,应用副词,填remarkably。
8.to drink 考查非谓语动词。根据语境可知,此处表目的,应用不定式,填to drink。
