第二节(满分25分)
47. 阅读下面材料，根据其内容和所给段落开头语续写两段，使之构成一篇完整的短文。
The first time we set eyes on “Big Red”, father, Frank, mother, Mary and I were on our way home. As we passed the Eaton’s department store’s window, we stopped as usual to have a look and do a bit of dreaming.
The beautifully decorated window display held the best toys ever. There were dolls much too pretty to play with. And they all lay beneath a surprisingly fantastic dress. Mother’s eyes were glued to its shining red satin (缎子).
“My goodness,” she whispered. “Look at that!” Then, mother looked down at her own coat-she had worn the heavy grey wool coat every winter for as long as I could remember. Mom was forever doing chores-washing laundry, tending the pigs and working in the garden-so she always wore housedresses and an apron (围裙) to protect the front. She did have one or two “special” dresses saved for church on Sundays. Also, she managed to make almost all of our clothes. They weren’t fancy, but they were comfortable.
“What a silly dress!” She shook her head. “Who on earth would want such a big dress ” As we continued down the street, mother turned her head for one more look. “My goodness! You’d think they’d display something a person could use!”
Mother’s Day was nearing, and the red dress was soon forgotten. Mother, of all people, was not one to spend money on items that were not practical. “There are things we need more than this.” She’d always say. Choosing a gift for Mother’s Day for her was quite hard. When Dad and I asked, she thought carefully then asked for some tea towels, face cloths or a new basin.

4、[成都石室中学]2025-2026学年度上期高2026届一诊模拟考试数学答案


【解析】图中为碱式滴定管，尖嘴向上，挤压乳胶管可排出气泡，A符合题意；用pH试纸测定溶液pH，不能将pH试纸插入溶液中，应该用玻璃棒蘸取少量溶液点在pH试纸上，B不符合题意；KOH能与石英中的SiO2反应，不能用石英坩埚加热熔融固体KOH，C不符合题意；向试管中滴加液体，胶头滴管应该在试管上方竖直悬空，不能插入试管中，操作不规范，D不符合题意。
常温下，下列溶液中的是（ ）。
氨水 B. 的溶液
C. 的盐酸 D. 硫酸
【答案】B
【解析】0.01mol/L氨水中，一水合氨发生部分电离，所以c(OH-)＜0.01mol/L， A不符合题意；pH=12的NaOH溶液，c(H+)=10-12 mol/L，则，B符合题意；盐酸为一元强酸，pH=2的盐酸，c(H+)=10-2 mol/L，，C不符合题意；H2SO4为二元强酸，则0.01 mol/L H2SO4中，c(H+)=2×0.01 mol/L=0.02 mol/L，，D不符合题意。
室温下，下列各组离子在指定溶液中可能大量共存的是（ ）。


12．有一包固体粉末X，可能含有碳酸钙、硫酸铜、硫酸亚铁、镁粉。为确定固体粉末的成分，现取X进行下列实验，实验过程及现象如下图所示(不考虑水、稀盐酸的挥发：碳酸钙与硫酸铜、硫酸亚铁不发生化学反应)。下列说法中正确的是

A．若气体1为纯净物，则原固体X一定不含有碳酸钙
B．若气体1为混合物，则溶液2中可能含有Fe2+、Cu2+、Ca2+
C．若溶液1呈无色，则固体粉末X中不可能含有硫酸铜
D．若溶液2呈浅绿色，则沉淀2一定是纯净物
13．某无色溶液中只可能含有、、、、、、、中的两种或几种，对其进行如下实验操作：(1)取少量溶液，滴加无色酚酞试液，酚酞变红；(2)另取少量溶液，加入足量BaCl2溶液，产生白色沉淀；(3)向(2)所得混合物中加足量盐酸，沉淀部分溶解，并有无色气体生成；
