Our first term of college life was 2 . We had a big telephone bill(账单) and our emails were really long. In the second term, I made some new friends, and I felt very 3 . I wanted· very much to let my new friends meet Becky.
When Becky finally visited me at my school, we were excited. She 4 a toy bear to me as a gift and told me about her college life. However, something happened when I introduced(介绍) her to my new friends. Her eyes grew dark and I could see the 5 in them. My new friends tried to share their friendship, but Becky didn't seem to accept(接受) it. I didn't understand . 6 the people I loved most couldn't love each other.
Becky left. I knew she was not happy. I thought long about what had happened. At last I understood. She saw me with my new friends and regretted(懊恼) that we no longer(不再) shared the same experiences(经历).
She saw all the fun I was having 7 her and wished she could be a part of it.
I wrote a letter to Becky 8 she was always my best friend. I told her everyone had friends from home and friends from school, and all the friends were life's greatest gift. Becky wrote back to me soon. She agreed and felt sorry about what she had done.
I think Becky and I both learnt an important lesson from it. 9 can influence(影响) our friendship and change the experiences we have shared. We are now walking on two different paths of life. While new friends are special and exciting, old friends are always there, 10 to share their heart and soul, no matter how far apart.

6、郑州市十校2025-2026学年上期高二年级期中联考试题(11月)数学答案

（2）H2SO4在水中的电离方程式为 ______。
（3）“浸铜”时发生反应的化学方程式为 ______。该反应中得到电子的元素为 ______（填元素名称）。
（4）“脱氯”后分离 CuCl固体与脱氯液的操作为 ______，需要用到的仪器有烧杯、______。
（5）已知 CuCl+FeCl3=CuCl2+FeCl2，该反应的离子方程式为 ______。
五、实验题：本大题共 1 小题，共 10 分。
21.如图是不同实验小组制备 Fe（OH）3胶体的装置。
（1）制备 Fe（OH）3胶体

B．②中在纯金属中加入其它元素，使原子层之间的相对滑动变得困难导致合金的硬度变大
C．③中烷基磺酸根离子在水中会形成亲水基向外，疏水基向内的胶束，而用作表面活性剂
D．④中石墨晶体是层状结构，每个碳原子配位数为3，属于混合晶体，熔沸点高
【答案】A
【解析】①属于超分子的一种，冠醚空腔的直径大小不同，超分子具有分子识别特征，其通过配位键识别特定的碱金属离子，A项错误；在纯金属中加入其他元素会使合金中原子层错位滑动变得更困难，从而提高合金硬度，B项正确；表面活性剂在水中会形成亲水基团向外、疏水基团向内的胶束，由于油污等污垢是疏水的，全被包裹在胶束内，从而达到去污效果。烷基磺酸根离子在水中会形成亲水基向外疏水基向内的胶束，C项正确；石墨晶体中每个碳原子以sp2杂化方式与同层其他碳原子形成平面网状结构，每个碳原子的配位数为3，碳原子之间形成的共价键键长较短，键能较大，因此石墨熔点很高。石墨层间则通过范德华力相互作用，同时石墨有类似金属晶体的导电性，因此可视作“混合晶体”，D项正确；故选A。
题型十 元素综合推断
【例10-1】（24-25下·广西南宁·期中）一种新型漂白剂(结构如图所示)可用于漂白羊毛等，其中W、Y、Z为不同周期不同主族的短周期元素，Z原子的核外电子排布式为，W、Y、Z的最外层电子数之和等于X的最外层电子数，基态X原子核外有两个单电子，W、X对应的简单离子的核外电子排布相同。下列叙述错误的是
