1、For years, the complex electrical signals inside the human brain were too difficult to decode. However, artificial intelligence (AI) is now turning the dream of "mind reading" into reality. At Stanford University, a 52-year-old woman, paralyzed by a stroke for 19 years, recently saw her internal thoughts appear as text on a screen. This was made possible by a tiny array of electrodes inserted into her brain, which worked with AI to translate her imagined speech into real-time words.
This breakthrough is part of a larger movement in neuroscience. In 2025, researchers in Japan introduced "mind captioning," a technique that uses AI and non-invasive brain scans to describe what a person is seeing or picturing. While these technologies are currently focused on helping patients with communication disabilities, such as those with ALS (渐冻症), they could eventually transform how all humans interact with each other and the world.
The journey to this point has been long. Scientists have studied brain-computer interfaces (BCIs) since the 1960s, initially focusing on physical movements. Early BCIs allowed users to control prosthetic (假体的) limbs or computer cursors, but decoding speech proved much harder. As neuroengineer Maitreyee Wairagkar explains, much of the early research was conducted on monkeys, who, despite being able to learn to move objects with their brain signals, simply cannot speak.
Recent progress, however, has been rapid. In 2021, a study showed that a paralyzed man could "write" 18 words per minute by picturing himself drawing letters in the air. By 2024, Wairagkar's lab trialled a new technique that translated attempted speech directly into text at 32 words per minute with 97.5% accuracy. Although this is still slower than natural human speech — which averages 150 words per minute — it marks a significant step toward everyday communication for those who have lost their voice. With companies like Neuralink seeking to bring these "brain chips" to the mass market, the era of commercialized BCIs may be just a few years away.
(1)、What is the function of the AI system mentioned in the first paragraph?A、To repair the damaged neurons of stroke patients. B、To stimulate the brain to produce clearer speech. C、To turn imagined speech into text on a screen. D、To predict the physical movements of paralyzed people.(2)、Why was the development of speech BCIs slower than movement BCIs?A、Early animal subjects were unable to provide speech data. B、Movement signals are more complex for AI to recognize. C、Non-invasive brain scans were not available in the 1960s. D、Previous researchers lacked interest in communication tools.(3)、What is the author's attitude toward the future of BCI technology?A、Doubtful. B、Optimistic. C、Objective. D、Critical.(4)、What is the author's main purpose in writing this passage?A、To promote Neuralink's new brain chip products. B、To question the reliability of brain-computer interfaces. C、To explain how AI is advancing mind-reading technology. D、To describe the historical development of BCI technology. -
2、Two years ago, fueled by my envy for those with gardens, I signed up for a plot, a place where I could read and write in the sun, safe from distractions. A few months ago, I was presented a half-plot of available land. The plot, which was bigger than I could dream of, was beautiful but overgrown — getting it started would require hard work. I wasn't sure I had it in me.
Fast forward to now. After seeking guidance from my family and watching beginners' gardening videos, I spend hours a week sowing, weeding, watering and harvesting. My summer at the plot has so far offered countless lessons, but the most important one has been learning more about how food actually grows. Take the humble cauliflower — a common sight in the supermarket, yet it demands patient tending for up to six months, all for a short moment on the plate. Seasonality has also taken on a new meaning. I knew that all fresh food has its "season" but it was only when I was overwhelmed by an endless supply of courgettes that I really understood I could be eating them for months.
Yet abundant harvests come with a lesson in impermanence. Fresh produce goes off quickly once ripened and picked. And so I've turned to the old craft of preservation — learning what to boil and freeze, or make into jam — to make things last. When the harvest has been more than I can manage, I've shared the abundance with friends and family, spreading the joy.
While gardening is a welcome escape from the chaos of the modern world, you can't avoid the reality of the climate crisis. It's one thing to read these in the news or see them reflected in prices, but it's quite another when you have to be in tune with weather patterns, praying for prolonged sunshine without the unbearable heat.
As I continue to tend my plot, I do so with a sense of humility, wonder and excitement. What started as a desire for a small patch of green has grown into something much more significant — a connection to my local environment, a respect for the food I eat and an awareness of the fragile natural systems that sustain us. In the beginning, I was worried I would fail the plot; instead, I'm finding myself growing alongside it.
(1)、How did the author feel when getting the plot?A、Proud but anxious. B、Grateful but puzzled. C、Amazed but worried. D、Moved but disappointed.(2)、While working on the plot, the author learned to ______.A、remove chaos from life B、respect laws of nature C、identify common plants D、create seasonal recipes(3)、What does the underlined word "impermanence" in paragraph 3 most likely mean?A、The quality of being short-lived B、The state of being abundant C、The condition of being easily preserved D、The feature of being seasonal(4)、What does the author's experience tell us?A、Labor is the most reliable wealth. B、Every season brings its own lessons. C、One should stay hungry for constant progress. D、The land is improved and so is the one who tends it. -
3、阅读下面短文,根据所给情节和给定段落开头语进行续写,使之构成一个完整的故事。
When I was six years old, I visited my grandfather's farm in Kansas and he sent me into the woods to gather pecans (胡桃) for us to enjoy later. The pecans were about the size of a man's thumbnail and just about the tastiest snack I'd ever had.
However, pecan picking was really tiring and my little bucket was only half full after working hard for a long time. I thought I wouldn't let Grandpa down. Just then something caught my eye. A large brown squirrel was a few feet away. I watched as he picked up a pecan, hurried to a tree, jumped up to the trunk and disappeared in a large hole. A moment later the squirrel popped back out and climbed down to the ground to pick up another nut. Once again, he took the pecan back to his hiding place inside the hollow of the tree.
Not so secret anymore, I thought. I dashed over to the tree and looked into the hole. It was filled with pecans! Golden pecans were right there for taking. This was my chance. Handful by handful, I scooped all of those pecans into my bucket. Now it was almost full! I was so proud of myself that I couldn't wait to show Grandpa all the pecans.
I ran back and shouted, "Look at all the pecans!" He looked into the bucket and asked, "Well, well, how did you find so many?" I told him how I'd followed the squirrel and taken the pecans from his hiding place.
Grandpa congratulated me on how smart I'd been in observing the squirrel and his habits. Then he did something that surprised me. He handed the bucket back to me and put his arm gently around my shoulders.

12、阅读下面短文,在空白处填入1个适当的单词或括号内单词的正确形式。
Did you grow up in one culture, your parents came from another, and you are now living in a (total) different country? If so, then you are a third-culture kid.
The term "third—culture kid" (use) in the 1960s for the first time by Dr. Ruth. She first came across this phenomenon while (research) North American children living in India. In general, third-culture kids benefit from (they) intercultural experience and they often reach excellent academic results.
Yet many (difficulty) may arise from this phenomenon. Third-culture kids may not be able to adapt themselves completely their new surroundings. Also, they often find it hard (develop) new friendship. Additionally, for a third-culture kid, it is often easier to move to a new country to return to his homeland. For example, after living in Australia for many years, Louis finally returned to the country she was born. She didn't know anything about current TV shows fashion trends. And she didn't share the same values as other teens of her age.

13、Sammie Vance approached her principal at Haley Elementary with the idea of installing "buddy benches" into her school playground to help others feel less lonely. The principal1 of the idea. But wooden benches are2. Just one would be worth nearly a thousand dollars. However, a bench made of3 bottle caps would only be around $250. So Sammie4 others in her community to collect enough caps to make one bench.5, she managed to get bottle caps from 50 states. And thus, the initiative of "Sammie's Buddy Bench Project" was6.
Pretty soon, Sammie's Buddy Bench Project began commanding the7 of several news media. For her amazing efforts, Sammie has been chosen the receiver of several8 and was9 one of People magazine's "Girls Changing the World". And10, more than 200 bottle cap buddy benches have been around at schools and parks across the country, plus Mexico and Australia.
This is, of course, not just a beautiful story about helping others. It's also a major win for11. It is reported that 1.3 billion bottle caps are used each year. These caps cannot be recycled in the same way along with plastic bottles12 each has a different melting point, and when they are13 in, it can ruin an entire batch (一批). And that's when they get discarded. Millions of caps have been found in our14 alone, which can be devastating to marine life. In fact, it's one of the leading15 of death. It's big caring hearts like Sammie's that help our planet heal against damage.

14、Imagine that you've just experienced something unpleasant-your friend has forgotten your birthday, you've been rejected for a new job, or you've just woken up after a long holiday and remembered you need to go to work. How would you typically respond to those feelings?
You might try to tell yourself that it doesn't matter, and not to let it get to you. This tendency could be described as "mood shame": The belief that having bad feelings is a personal failing.
Continually looking on the bright side of life might seem strong, even courageous. While it's natural that we might prefer to avoid uncomfortable feelings like disappointment, worry, anger, or sadness, a recent psychological research supports the idea that they serve useful purposes in our lives. By learning to see that value and accept those feelings without judgment, we may enjoy better physical and mental health.
Consider anxiety. We may assume that anxious feelings destroy our concentration and reduce our performance on difficult tasks—that we can only succeed in an exam or an interview if we learn to relax. Alternatively, we can see the feeling as a source of energy. Besides, disappointment may make us feel unpleasant-but you could recognize that the emotion helps us to learn from our mistakes. And by assigning a more positive meaning to the feeling and acknowledging its potential uses—rather than feeling it is somehow unhealthy—you might change the brain and the body's responses to an upset.
Rather than judging yourself toughly for bad feelings, you might lean into that bad mood, and allow yourself the self-care you need to get through it. Without fighting the emotions themselves, you could start to question whether those feelings have value. Perhaps they'll help you to identify an important change in your life.
(1)、What do the underlined words "get to" in Paragraph 2 mean?A、Bother. B、Cheat. C、Scare. D、Inspire.(2)、What can we learn from the psychological research in Paragraph 3?A、Being negative leads to bad health. B、Being positive means having courage. C、Positive feelings improve working efficiency. D、Negative feelings may have positive effects.(3)、How does the author prove his idea in Paragraph 4?A、By analyzing causes. B、By giving examples. C、By presenting research results. D、By making definitions.(4)、What does the last paragraph mainly talk about?A、The causes of bad feelings. B、The evaluation of bad feelings. C、The consequences of bad feelings. D、The suggestions for handling bad feelings. -
15、For his eleventh birthday, Lin was given a gift that would shape his life. On that day his father took him to the Children's Activity Centre and said he could choose any course that interested him. There was just one requirement: Lin would have to promise to study it for at least one year.
To that point Lin had had many hobbies, but none kept his interest for more than a week or two. His mum once gave him a bag of stamps to encourage stamp collecting. That hobby lasted a week. Then his father got him some paints hoping that Lin's artistic side would shine through. Those paints were now under his bed, still unopened. This time Lin's parents would let him decide.
Lin's eyes moved down the noticeboard that listed all the courses on offer. He stopped at "Photography". He liked the idea of taking beautiful pictures but the notice said that each student needed their own camera. Although Lin's family weren't poor, they weren't rich either, and a camera cost a lot of money. He continued looking.
The next course to catch his eye was "Language Art". He didn't even know what that meant. His father explained that it taught people how to make public speeches. Lin, a shy boy, could think of nothing worse.
Then he saw it. "Cooking" sounded like something he'd like to do. It was inexpensive and convenient, it could be done alone and it was also creative.
Based on Lin's hobby history, his dad had doubts, but he agreed. Much to his parents' surprise, Lin kept his promise. He studied cooking at the Centre every Saturday, and practised at home, making delicious meals for his family. Everyone looked forward to birthdays, when they could eat his cakes. Lin got great satisfaction from the pleasure his food brought to others.
The months turned to years but his hobby never changed again.
Now Lin is an adult and runs a successful restaurant. When customers say they enjoy his meal, he still gets the same pleasure he did as a child, and remembers the special gift he received all those years ago.
(1)、The underlined expression "catch his eye" in Paragraph 4 means ______.A、make him excited B、cause him surprise C、get his attention D、help him see clearly(2)、Which of the following best describes Lin's interest in cooking?A、It only lasted for a short time. B、It seemed to match his character. C、It was forced on him by his parents. D、It developed slowly over many months.(3)、Why did the father have doubts about Lin's choice of cooking?A、Lin wasn't good at cooking. B、Cooking wasn't very convenient. C、He didn't think Lin would continue. D、Cooking wasn't a good hobby for a boy.(4)、What would be the best title for the passage?A、A Strict Father B、A Changeable Boy C、The Fun of Cooking D、The Birthday Gift -
