华理曙光中学最新高一期中考试卷,中考140分+,这道完型题真的不算难!

2026-11-14 10:47

曙光这篇完型就出题而言，整体属于上海高一完形中等难度，接近春考完形的科普风格。

词汇层面：大部分单词在高一拓展范围内，但有少量科普术语auditory cortex听觉皮层、sensory filter感官过滤器、prey猎物等，属于生物学神经科普，学生平时接触不多，容易读着有距离感；固定句型（it occurs to sb.），校内课本不反复重点操练，属于拉开分差的点；

逻辑层面：不同于故事类完形（情感、情节好理解），科普文讲究实验因果、对比逻辑，学生习惯顺着语感做题，很容易逻辑颠倒。这

得分参考（高一学生）：

👉基础一般的生容易错5–8空；

👉基础扎实、平时常读科普阅读的学生可以控制在错2–3空；

👉初中学生，也可以拿到满分哦

Brain’s Special Sound Skill

You’re walking down a quiet street and suddenly you hear some footsteps. ___31___ , it means that there’s someone around. But have you ever wondered why it ___32___ to us that it’s someone else’s footsteps rather than ours?

According to a new study published in the journal Nature in September, this phenomenon results from a function in our brain to ___33___ the noises we make ourselves.

In order to ___34___ how our brain does this, a group of scientists from New York University in the US carried out an experiment with mice at Duke University. In the experiment, researchers ___35___ the sounds a group of mice could hear, reported Science Daily.

During the first several days, the mice would hear the same sound each time they took a step. This was just like “running on a tiny ___36___ with each key playing exactly the same note”, senior study author Richard Mooney, a professor of neurobiology at Duke University, told Live Science.

Scientists found that their auditory cortex (听觉皮层) – the area of the brain that processes sound – became active at first but ___37___ its response to the sound after two or three minutes when the mice became familiar with it.

“It's almost like they were wearing special headphones that could ___38___ the sound of their own movements,” David Schneider, an assistant professor at the Center for Neural Science at New York University, told HuffPost. But once the sound changed, their auditory cortex was ___39___ again.

This suggests that the “sensory filter” in a mouse’s brain could help it detect ___40___ sounds or abnormal noise in the environment easily after tuning out familiar sounds, according to Science Daily.

“For mice, this is really important,” said Schneider. “They are prey (猎物) animals, so they really need to be able to ___41___ for a cat creeping up on them, even when they’re walking and making noise.”

As important as it is for mice’s survival, the ability to ignore ___42___ noises is also useful for humans when it comes to complex tasks, such as playing an instrument.

According to Schneider, “the ability to ignore the ___43___ consequences of our movement gives us the extra-cool ability to detect when we’ve got it wrong. So if I play the piano just right, I hear it, but my auditory cortex is pretty silent. But when I play it wrong, I get a (n) ___44___response.”

So, our ___45___ could be telling us, “Hey, that didn’t sound right, maybe I should move my fingers a little different next time,” Schneider told HuffPost.

答案：31. D 32. B 33. D 34. A 35. C 36. B 37. B 38. A 39. C 40. A41. D 42. B 43. B 44. C 45. A

★文章主要内容：

本文是一篇科普完形，介绍大脑的感官过滤机制。

我们走路听到脚步声，能分辨出是不是自己发出的声音，这个现象来自大脑的一项功能：主动忽略自身动作产生的噪音。科学家用小鼠做实验：小鼠每迈出一步就伴随固定声音，一开始小鼠听觉皮层反应强烈，熟悉之后反应就减弱；一旦声音改变，听觉皮层会再次激活。这套“感官过滤器”对小鼠生存至关重要——小鼠是被捕食动物，屏蔽自己走路的声音，才能听见天敌悄悄靠近的声响。这套机制人类同样拥有：比如弹钢琴时，大脑会预判、忽略动作本该发出的正确声音；一旦弹错，声音和预期不符，听觉皮层就会产生强烈反应，提醒我们出错了。

★详解：

31. D Of course

解析：前文说在街上听到脚步声，当然这意味着附近有人。顺承逻辑，不是转折、递进。

32. B occurs

解析：固定句型it occurs to sb. that…某人想到/在某人看来……；happen to sb. 意思是“某事发生在某人身上”，不符合句型。
