[九师联盟]2026届高三3月30日质量检测历史HB试题

【答案】1. D 2. C 3. A
B
When a hurricane hit her hometown, Karen Lauder chose to stay at home because she didn’t know how strong the storm would be. Karen was 84 years old and depended on a wheelchair to get around because she was missing a leg. Her son, Johnny Lauder, tried repeatedly to get her to leave, but she refused.
Johnny and his whole family live within a few blocks of one another. They kept in touch with Karen as the storm continued violently (猛烈地) outside, watching the water rising dangerously all around them. When Karen reported that the water in her house had reached her bottom, Johnny knew he had to take action.
First, Johnny ensured his sons and their pets were taken care of. Then, he jumped out of a window and began to swim. Johnny used to work as a rescue swimmer. He is obviously a strong swimmer, but the flood water was filled with dangerous materials. There was also a strong current (水流), and he had to swim against it for most of his trip to Karen’s. As he made his way through the water, Johnny stopped periodically to snap selfies (自拍) to show his worried family that he was okay.
Johnny was racing against the clock. He knew he only had a short period of time to get there before the water rose above Karen’s head. It took him 40 minutes to swim four blocks. The sound of Karen shouting inside was music to his ears!
“If it would’ve been 20 minutes later, she wouldn’t be here,” Johnny said. “She’s never been happier to see me.”

6、[九师联盟]2026届高三3月30日质量检测英语HB答案

(2)将R2的滑片滑至下端，R2阻值最大，保护灵敏电流计G。
(3)由图丁可得Rx阻值为Rx＝＝500 Ω。
(4)采用图丙实验方案测得的电阻值误差更小，主要原因是电压表测量的电压始终等于待测电阻两端的电压，电压表不会分流，避免了电压表分流作用，消除了系统误差。
答案：(1)大于　小于　(2)保护灵敏电流计G　
(3)500　(4)见解析
13.(10分)如图所示，一玻璃柱体的横截面积由半径为R的半圆AEB和等腰直角三角形ABC组成，O为圆心，AB为竖直直径，ED垂直于AB相交于O。平行于ED的光线GF从F点射入玻璃体，刚好经过D点，∠EDF＝30°，光在真空中的传播速度为c。求：
(1)玻璃的折射率；(5分)
