不止一个学生去过北京。 2．不定代词作主语时的主谓一致 (1)当主语被不定代词修饰或主语本身是不定代词时，谓语动词的形式需要根据主语加上修饰语后整体表达的意义来进行判断。 Every means has been tried out without much result.所有方法都试过了，却没有什么效果。 All of the work is done by me.所有工作都是我做的。 (2)当主语被否定词修饰或主语本身是否定词时，谓语动词一般用单数 形式。 Nobody has got a ticket.谁都没有票。 Nothing was available.没有可用的。 名师点津　当none作主语或主语被none修饰时，谓语动词一般用单数形式，但如果主语为可数名词复数在非正式表达中，谓语动词也可用复数 形式。 None of the pizza is

new items, but it doesn't break down in the environment and will sit in landfills for thousands of years.A team of Chinese scientists aimed to deal with this environmental concern by developing an eco-conscious alternative. In a study published recently in the journal Science Advances, a team at the Chinese Academy of Sciences' Institute of Process Engineering describe how they engineered biodegradable glass made from amino acids(氨基酸)．That glass would have a smaller impact on the environment and can break down in a few weeks or in several months. In a test, glass beads(玻璃珠) made out of amino acids were placed under the skin of mice, and the breakdown of the bead and the skin healing process were observed for 30 days.A diagram from the study shows how the mice's bodies broke down the beads.In that month, the glass implant degraded(降解) beneath the skin, the wound site healed, and fur grew back.“Throughout the experimental period, no mice showed any pain-related behavior that may have been caused by the glass implantation, and none of them experienced obvious weight loss，” the researchers wrote in their paper. Although amino acids do degrade over time in the environment, this biodegradable glass is not as durable as traditional glass, because amino acids can break down quickly in heat.In order to overcome this barrier, the researchers chemically modified the amino acids using the heating-cooling procedure applied in glass making.This is when materials for the glass are heated to become soft and then rapidly cooled so as to make the glass tougher. “It's important to point out that this biodegradable glass is currently in the lab stage, and far from large-scale commercialization，” emphasized Yan Xuehai, a professor involved in the study, in a press release. 语篇解读　本文是一篇说明文。文章主要介绍了中国科学院的专家团队利用氨基酸研制出一种可降解的环保玻璃。 √ 1．What did the researchers study during the experiment? A．The mice's skin healing process. B．The breakdown of the glass beads. C．The medical value of the new glass. D．The glass degradation with less injury to the mice. 细节理解题。根据第三段中的“‘Throughout the experimental period... experienced obvious weight loss，'the researchers wrote in their paper.”可知，研究人员在实验中研究出玻璃降解对老鼠损伤较小。故选D。 √ 2．How do the researchers improve the durability of amino acid glass? A．Adding more amino acids. B．Heating the glass and rapidly cooling it. C．Using special chemical substances. D．Changing the producing process of glass. 细节理解题。根据倒数第二段“This is when materials for the glass are heated to become soft and then rapidly cooled so as to make the glass tougher.”可知，研究人员加热玻璃并迅速冷却来提高氨基酸玻璃的耐久性。故选B。 √ 3．What does the underlined word “modified” in Paragraph 4 mean? A．Transformed. B．Melted. C．Enlarged. D．Produced. 词义猜测题。根据画线词上文“In order to overcome this barrier, the researchers chemically”以及下文“the amino acids using the heating-cooling procedure applied in glass making”可知，为了克服这一障碍，研究人员使用玻璃制造中应用的加热-冷却程序对氨基酸进行化学转换。故画线词意思是“转换”，与A项意思相近。故选A。 √ 4．Which of the following can be the best title for the text? A．A New Kind of Perfect Glass B．Amino Acids Make Glass Tougher C．Large-scale Commercial Glass Products D．Environment-Friendly and Biodegradable Glass 标题归纳题。通读全文，并结合第一段内容可知，文章主要介绍了中国科学院的专家团队利用氨基酸研制出一种可降解的环保玻璃。故D项最适合作文章标题。故选D。 Ⅱ.完形填空(每小题1分，共15分) (2025·广东省佛山市高二上期末) 10-year-old Jack created a plastic minifigure (人偶) that looks much like him.Fondly named “Mini Jack”， the toy was carried with him wherever he went.
