1、重庆市高2025届高三第七次质量检测(2025.3)化学试题


A lone arctic fox walks slowly across a white, treeless tundra, hungry for a meal. She can’t see her prey (猎物) that lives under the snow, but she can hear it. She smells the ground, jumps several feet straight into the air, and dives (潜入) into the snow, nose first. For a moment, her upside-down body is frozen in mid-air. Then she rights herself, her prey captured. Until spring arrives this arctic fox will rely on many cold-weather strategies to survive in the frozen tundra.
Foxes are smart, storing extra food under rocks for later or following polar bears to eat the leftovers from their kill. They are fast, running up to 30 miles per hour. And they are cute. The fox’s beautiful white coat acts as camouflage in the winter, while its gray fur matches the tundra’s rocks and plants in the summer. When it sleeps, it wraps its long, fluffy tail around its body like a blanket (毯子) and an extra layer of fur on its broad paws allows it to walk quietly on ice and snow.
Cuteness aside, the arctic fox is a hardy survivor, able to withstand extremely cold Arctic temperatures. Its thick fur is the best at keeping it warm, maintaining a comfortable body temperature of 40℃. It has excellent hearing and a sharp sense of smell that can sense a dead body left by a polar bear from as far as 24 miles away.
In general, the arctic fox is considered a species of “least concern” around the coldest parts of the Arctic. However, in Norway, Sweden, and Finland its population is severely endangered, numbering less than 200. Climate change is thought to be the main cause. With warmer temperatures, there is less snow cover, so the arctic fox’s light-colored fur doesn’t help it match its surroundings as well. The larger red fox is outcompeting the arctic fox, because it has a more varied diet; the red fox can eat human waste it finds along mountain roads. Also, insects that are now surviving farther north are eating the plants in the tundra, which affects the fox’s habitat and limits the numbers and types of animals they can cat.
12. Which word can best explain the underlined “camouflage” in paragraph 2
A. Hiding. B. Attraction. C. A blanket. D. A tool.
13. What does paragraph 3 mainly focus on about Arctic foxes


5．他们为了寻找安全，走了几百公里。hundred，名词，百。根据文中的"of kilometres"可知，此处需要一个名词来表示他们走的距离，结合短语"hundreds of"表示"数百"，表示他们走了几百公里。故填 hundreds。
6．他们为了找到安全而逃跑。safe，形容词，安全的。根据动词"find"可知，此处需要一个名词来表示他们寻找的东西，即安全。故填 safety。
7．Ark最终到达了另一个国家。final，形容词，最终的。此处应用副词修饰动词"made"，表示最终到达。故填 finally。
8．从书里赚的钱已经用来帮助他的国家的人民了。go，动词，去。根据文中的"to help people of his country"可知，此处描述的是钱的去向和用途，由于这是从过去一直持续到现在的动作或状态，并且可能还会持续下去，所以时态应使用现在时的完成时态。构成形式是"have/has + 过去分词"，"has gone"表示钱已经用于帮助他国家的人民了，且强调的是从过去到现在的这段时间内钱的去向。故填 has gone。
9．is included；is expressed；was discovered；was drunk；will be liked
文章大意：本文主要讲述了茶文化。
（1）众所周知，茶文化是中国文化的一部分。 include包括，动词。主语tea culture 和谓语动词include之间是被动关系，所以需用被动语态，根据As is known to all可知该句为一般现在时的被动语态，主语是单数，be动词需用is，后需接include的过去分词included。故答案为is included。
