Passage 1
Topic：The Secrets of Human Brain Capacity
We often think our inner world is more complex than what we can express. Elon Musk's idea of a brain-computer interface might seem like a solution, but recent research tells a different story.
36_______ The study in Neuron reveals that human thinking occurs at a sluggish pace of around 10 bits per second. However, our sensory systems work at a staggering speed of about one billion bits per second. 37 _______This vast difference creates the so-called "Musk illusion," where we wrongly believe our minds can handle multiple thoughts simultaneously.
Markus Meister, a leading neuroscientist, points out that the human brain is less remarkable than we assume. 38_______ For instance, it is much slower in decision-making compared to modern devices. Even if Musk were to achieve his goal, the communication speed with the computer wouldn't be significantly faster.
Another aspect is that our brains only focus on a limited amount of sensory information. Past studies lacked a quantitative understanding, which Meister and Zheng aimed to address. 39______ Their research showed that the total knowledge a person acquires in a lifetime is surprisingly small.
In conclusion, our senses give us the impression of vast perception, but it's an illusion. 40________ Understanding these limitations helps us better comprehend the true nature of our brains.
A. They collated data from various fields.
B. This speed gap has significant implications.
C. So, what is the real situation
D. It struggles with multitasking.
E. The illusion persists in our minds.
F. Why does this happen
G. Our perception is often deceiving.

37 题：上文对比了人类思维速度和感官系统速度，B 选项 “这个速度差距有重大影响” 承接上文，进一步说明其影响，符合逻辑。
38 题：上文说大脑不如我们想象的强大，D 选项 “它难以同时处理多项任务” 具体说明了大脑的这一局限性，与上文连贯。
39 题：上文提到 Meister 和 Zheng 的研究目的，A 选项 “他们整理了来自不同领域的数据” 说明他们为了填补空白所做的工作，符合文意。
40 题：上文说我们的感官给我们错误的印象，G 选项 “我们的感知常常具有欺骗性” 对上文进行总结，符合语境。
Passage 2
Topic：Unraveling the Mysteries of the Human Mind
Many of us feel that our thoughts and feelings are too profound to be fully expressed. Elon Musk's pursuit of a direct brain-computer connection is an attempt to overcome this "communication barrier." But new findings suggest otherwise.
36_______Research published in Neuron indicates that human thinking speed is fixed and extremely slow, approximately 10 bits per second. Meanwhile, our sensory systems are incredibly efficient, gathering data at a rate of one billion bits per second. 37_____ This disparity gives rise to the false perception that our minds are capable of juggling numerous thoughts at once.
Meister, a renowned neuroscientist, emphasizes that the human brain is not as extraordinary as we might believe. 38_____ Its decision-making process is painstakingly slow, much slower than the technology we use daily.
Our brains selectively process only a fraction of the information our senses receive. Previous studies overlooked the importance of quantifying this. 39____ By doing so, they discovered that the amount of knowledge a person can accumulate in a lifetime is relatively limited.
To sum up, the human brain has its own set of limitations and peculiarities. 40_____ These revelations prompt us to reevaluate our understanding of the mind.
A. Their research filled the void.
B. This contrast is quite astonishing.
C. What lies beneath these phenomena
D. It can't handle complex decisions quickly.
E. We are often misled by our senses.
F. How did they conduct the research
G. Understanding these is crucial for us.
答案：36. C 37. B 38. D 39. A 40. G
解析：
36 题：上文提到马斯克的尝试与新发现的矛盾，C 选项 “这些现象背后隐藏着什么呢？” 引起下文对人类大脑现象的深入探讨，符合语境。
37 题：上文对比了思维速度和感官系统速度，B 选项 “这种对比相当惊人” 承接上文，对速度对比进行评价，符合逻辑。
38 题：上文说大脑不像我们认为的那么厉害，D 选项 “它不能快速处理复杂决策” 具体说明大脑在决策方面的不足，与上文连贯。
39 题：上文提到之前研究的不足，A 选项 “他们的研究填补了这个空白” 说明 Meister 和 Zheng 的研究成果，符合文意。
40 题：上文总结了大脑的局限性和特点，G 选项 “理解这些对我们来说至关重要” 强调了解这些情况的重要性，符合语境。
Passage 3
Topic ：The Enigmatic Human Brain Capacity
Have you ever wondered why you can't fully express all your inner thoughts Elon Musk's idea of a brain-computer interface is aimed at solving this problem. However, new research has uncovered some unexpected truths.
36_____ A study in Neuron shows that human beings think at a remarkably slow speed of about 10 bits per second, while our sensory systems operate at a lightning-fast speed of around one billion bits per second. 37_____ This huge gap results in the false impression that our minds can engage in multiple thoughts simultaneously.
Markus Meister, a respected neuroscientist, states that the human brain is less impressive than we imagine. 38_____ For example, it is much slower in making decisions compared to the devices we interact with every day.
The new research builds on past psychological studies. It reveals that we only pay attention to a small portion of the sensory information. What was missing in previous research was a numerical perspective. 39_____ Through their work, they calculated that the total amount of information a person can learn in a lifetime is not as large as we might think.
In conclusion, our understanding of the human brain is constantly evolving. 40_____ These new insights help us better understand our own minds.
A. They gathered data from multiple sources.
B. This difference is quite remarkable.
C. So, what are the real capabilities
D. It has difficulties with quick decision-making.
E. Our perception is often inaccurate.
F. Why is there such a gap
G. Keeping up with the research is important.
答案：36. C 37. B 38. D 39. A 40. G
解析：
36 题：上文提到马斯克的想法与新研究的冲突，C 选项 “那么，真正的能力是什么呢？” 引出下文对人类大脑实际能力的探讨，符合语境。
37 题：上文对比了思维和感官系统的速度，B 选项 “这种差异相当显著” 对速度差异进行描述，符合逻辑。
38 题：上文说大脑不如想象中厉害，D 选项 “它在快速决策方面有困难” 具体说明大脑的这一弱点，与上文连贯。
39 题：上文提到之前研究缺乏数值视角，A 选项 “他们从多个来源收集数据” 说明 Meister 和 Zheng 为填补空白所做的工作，符合文意。
40 题：上文说我们对大脑的理解在发展，G 选项 “跟上研究的步伐很重要” 强调了解大脑研究的重要性，符合语境。
