[衡中同卷·天舟益考]2026届高三联合质量检测(12月)数学试题

（C）
Which animal is the fastest hunter on land The answer is the cheetah (猎豹). A cheetah weighs from 40 kg to 65 kg when it grows up. Its body is as long as from 115 cm to 135 cm. It is difficult to tell if a cheetah is “him” or “her” by its looks alone, although “he” seems to be a little larger than “her” and usually has bigger heads.
But you can easily tell leopards (豹子) from cheetahs: Cheetahs are shorter in body, but they have longer tails and legs, so they seem more streamlined (流线型的). A cheetah can run as fast as a car. And no matter how fast it runs, it holds its head still (不动的): This way, it can centre on its prey (猎物) while running after it. How does a cheetah do this
Cheetahs have special inner ears. The inner ears are the inner part of the ears, which help the body stay balanced. The cheetah’s inner ears can feel small changes and send information to its head quickly. As a result, a cheetah can hold the head still to centre on preys, and keep balance when it changes direction while running.
Scientists believe that, a long time ago, cheetahs didn’t have this kind of inner ears like they do today. They only had thin bones that allowed them to run very fast. Later, they grew special inner ears to help them “lock onto” their preys while running fast.
33．Which of the following is probably the weight of a grown-up cheetah
A．30 kg. B．50 kg. C．70 kg. D．90 kg.

4、[衡中同卷·天舟益考]2026届高三联合质量检测(12月)数学答案

【答案】A
【解析】图甲是固态分子的模型,固体中的分子间距离最小、作用力最大,固体有固定的形状和体积,一切物质的分子都不停地做无规则运动；图丙是气态分子的模型,分子间距离最大、分子间作用力最小；图乙是液态分子的模型,图丙是气态分子的模型,图乙、丙所表示的物质均可流动。
1.（2025年江苏无锡中考题）同时在装有冷水和热水的两个烧杯中各滴入一滴红墨水，发现热水中的红墨水扩散得快。这个现象说明【 】
A. 分子之间有吸引力 B. 分子之间有排斥力
C. 热水分子比冷水分子小 D. 温度越高，分子无规则运动越剧烈
【答案】D
【解析】扩散现象是分子在不停地做无规则运动的体现。在热水和冷水中分别滴入红墨水，热水中的红墨水扩散得更快，是因为热水温度高，水分子（以及红墨水分子）的无规则运动更剧烈，使得红墨水分子能更快地在水中分散开来。
