    Emma had never read it, nor had she ever purchased a copy. But, when she opened it up, she was floored to see her own name and address inside the cover, in her own handwriting. It turned out that the summer before, at a concert back in Montreal, Emma had met a Californian who was in town visiting friends. They decided to exchange addresses, but neither of them had any paper. The man had opened up a book he was carrying in his backpack and asked Emma to write her name and address inside. When he returned to California, he left the book behind in Montreal, and his friend Alex kept it. When Alex later relocated to Jerusalem, he took the now-treasured book along.
    Q: What does the underlined word “floored” in the paragraph mean
    A. interested B. shocked C. frightened D. excited

    Oxygen is vital to life; it is needed by the body cells of all animals. It is also very useful in industry. The method Priestley used produces only small quantities. The large amounts needed for industry are produced in a different way. Air is put into containers under great pressure. This turns it into liquid and makes it very cold. It is then gradually warmed up and each substance evaporates at a different temperature. The boiling point of oxygen is -183°C. It is caught and stored in strong steel cylinders at a pressure of 136 atmospheres. The process is known as fractional distillation.
    Q: Which word has the rough meaning of “vital”

    5、山西省2024-2025学年高三巩固提升卷(4月)生物学答案


    17. 我国是世界上锌冶炼最早的国家。明代江西人宋应星所著的《天工开物》中有关“火法”炼锌的工艺记载是：“每炉甘石(主要成分是碳酸锌)十斤装载入一泥罐内……然后逐层用煤炭饼(反应后生成一氧化碳)垫盛，其底铺薪，发火煅红……冷定毁罐取出……即倭铅(锌)也。”此工艺过程分解模拟如图。(已知：Zn的冶炼温度为904℃，沸点为906℃。)请结合图文信息，分析思考，解决问题：
    （1）装入原料器之前，将炉甘石敲碎的目的是___________。
    （2）高温炉内，碳酸锌()在高温条件下与煤的主要成分发生反应生成Zn和一种可燃气体，反应的化学方程式为___________。该反应生成物中碳元素的化合价为___________价。
    （3）我国古代冶锌晚于铁和铜，结合已知信息，分析说明其中的原因是___________。
    四、实验与探究题(本大题共2小题，共16分)
    18. 二氧化碳在生活和生产中具有广泛用途，一直备受人类关注，小明同学利用大理石碎片进行相关实验，结合图1实验装置回答问题：
    （1）标号①的仪器名称是___________。


    ④再点燃酒精灯加热。
    下列说法不正确的是
    A. ①中若注射器活塞弹回，则说明装置气密性良好
    B. 只有实验④红磷燃烧
    C. 由实验②③可得出燃烧需温度达到着火点
