1 . If a pancake could dream, it might long for legs so it could jump off your breakfast plate in pursuit of a better, unchewed life. But legs aren’t necessary for something as flat as a pancake to jump around. A group of scientists have designed a pancake-shaped robot that can jump several times per second and higher than seven times its body height. The new robot named Hop, which swiftly jumps without feet, is an important contribution to the soft robotics.
Many ground robots move by rolling or walking. But it’s more efficient for robots to jump over obstacles (障碍物) than to go around them. Although jumping can offer some robots a competitive edge, engineering that ability has been a challenge for robotics researchers. Some soft robots that store energy can perform a single impressive jump very infrequently. Some lightweight soft robots that don’t store energy can jump frequently but can’t jump high or far enough to successfully cross an obstacle.
For inspiration, the researchers looked to gall midge larvae (瘿蚊幼虫) that miraculously throw themselves across distances 30 times as long as their loglike bodies. A gall midge larva bends its body and squeezes the liquid in its body to one end, making it rigid (僵硬的). The accumulation of liquid builds up pressure, and releasing the pressure sends it soaring (飙升). The robot’s body doesn’t resemble (像) that of a gall midge larva, but it jumps like one. Its body is made of two small plastic bags printed with electrodes; the front bag is filled with liquid and the back one is filled with the same volume of air. The robot uses electricity to drive the flow of liquid, which causes the body to bend and generate force with the ground, resulting in a jump. And the air bag imitates the function of an animal’s tail, helping the robot keep a stable position.
While the robot is currently restricted to Earth, it might be right at home exploring another planet. If this is true, the researchers robot might jump over dusty rocks and large holes on the moon or Mars, going where no pancake has gone before.

2 . Twelve-year-old Catherine has a lot of friends—632, actually, if you count up her online friends. And she spends a lot of time with them.
But is it possible that Catherine’s online friendships could be making her lonely? That’s what some experts believe. Connecting online is a great way to stay in touch, they say. However, some experts worry that many kids are so busy connecting online that they might be missing out on true friendships.
Could this be true? During your parents’ childhoods, connecting with friends usually meant spending time with them in the flesh. Kids played Scrabble around a table, not words with friends on their phones. When friends missed each other, they picked up the telephone. Friends might even write letters to each other.
Today, most communication takes place online. A typical teen sends 2,000 texts a month and spends more than 44 hours per week in front of a screen. Much of this time is spent on social media platform.
In fact, in many ways, online communication can make friendships stronger. “There’s definitely a positive influence. Kids can stay in constant contact, which means they can share more of their feelings with each other,” says Katie Davis, co-author of The App Generation.
Other experts, however, warn that too much online communication can get in the way of forming deep friendships. “If we are constantly checking in with our virtual world, we will have little time for our real-world friendships,” says Larry Rosen, a professor at California State University. Rosen also worries that today’s kids might mistake the “friends” on the social media for true friends in life. However, in tough times, you don’t need anyone to like your picture or share your blogs. You need someone who will keep your secrets and hold your hand. You would like to talk face to face.

I sat in the breakfast corner with my four-year-old son, Matthew, trying to ignore the ache in my stomach. I was still recovering from a surgery. I hoped for strength and happiness. But the future seemed so hopeless.
Matthew jumped up from his spot on the kitchen floor. “Bird!” he shouted, rushing to the sliding door. Sure enough, there was a white dove seated on a rubber tree. It sat there a few moments, and then flew away. I’d never seen one in our neighborhood before.
When I dragged myself to the kitchen the next morning, the dove was back. This time it was with a mate carrying twigs (嫩枝), “Look, Matthew,” I said, pointing to the tree. “They’re going to make a nest.” The doves flew in and out of the courtyard all week, building on the top of the rubber tree. Matthew could hardly contain his excitement. Every morning, he’d run into the kitchen and take his spot by the sliding glass door, talking to the birds while they worked. As much as I was grieving (感到悲伤), I couldn’t help but look forward to the doves’ visits too. We watched their progress as if it were a real-life soap opera unfolding before us. Gradually, my pain disappeared, replaced by joy.
Then it all went wrong. The courtyard was a safe enough spot for a nest, but the rubber tree’s broad, thin leaves were far from stable. One night, a strong wind blew through, throwing the doves’ nest to the ground. I heard the twigs break apart. Nothing good ever lasts. I wouldn’t blame the doves if they never came back. But they returned. And they paid no attention to the pi le of sticks that had once been their nest. They started again from scratch, though the wind destroyed all their hard work. The next day, and the next, they renewed their efforts, as if nothing had happened.

The words “caring” and “empathetic” (共情的) aren’t ones normally associated with technology. Yearsley, an Australian enterpriser who is expert in artificial intelligence (AI), is trying to change that.
Yearsley is the founder of Akin, a robotics startup that currently uses a tablet-based system to help users manage the tasks related to home life, whether that’s planning meals or reminding you to pay your cell phone bill. Current home devices made by Google or Amazon or Apple use predictive AI to track patterns, strengthen behaviors and manipulate (操控) buying decisions, some of which, she assumes, are questionable or just unhealthy.
In contrast, the AI that she is developing will be designed to run the human home, encouraging healthful decisions such as taking a nightly walk, refilling the fridge and supporting social interactions like lunches or birthday celebrations with friends. “It’s the hardest AI I have ever built for it’s a complex system,” Yearsley says.
Yearsley began developing the Akin technology in 2017, when she realized the need to better manage the home is hugely ignored. Besides, she realized that women unequally bear the burden of household work. A United Nations’ report estimates that women do2.6 times the amount of unpaid care and domestic work that men do, or close to 30 hours per week in the U. S. alone.
While Yearsley pictures an army of robots someday helping with routine homemade tasks, the first display for Akin will take time and money. Akin has received some early seed money from a handful of investors, and was recently selected as a finalist for tech giant LG Nova’s Mission for the Future program, an annual challenge that seeks to identify businesses having potential to improve life and lead society into the future.
1. What might the Akin’s AI system suggest?| A．Consuming more drinks to enjoy yourself. | B．Staying up late working to make more money. |
| C．Spending more time staying with your family. | D．Purchasing products that may attract you. |
| A．The high cost of current home devices. | B．Akin’s becoming a finalist for a program. |

7 . J. K. Rowling frequently shows there is magic every day. Her Harry Potter series has helped people through times of stress and depression and she is always there to deliver wise words of encouragement.
She is one celebrity who is very active on Twitter. So when a single dad named Matt Burke sent her a message thanking her for the series, she noticed. Her series had helped strengthen his relationship with his 9yearold daughter Bailey.
He included a link to his article titled Being a Broke Parent. He explained how he hadn’t found a level of financial stability that allowed him to pay bills on time and take his daughter on more activities and events. The family also doesn’t have the Internet or TV, which means there’s no “digital babysitter” and he has to rely on his own creative ways to bond with his daughter. Since he received the series, the main thing that has occupied them these days is reading books together.
Burke admits that he thought he was “too cool” for the books when they first came out and he was in his twenties, but he’s loving reading them now. “We switch off chapter by chapter reading them out loud，“Burke explains.” This not only allows her to get more used to reading aloud in front of someone, but it gets me directly involved in something she loves, and it gives me the chance to be very dramatic when I read my chapters and bring myself into the characters in the book, which has proven to be a ton of fun.”
After hearing Burke’s story, Rowling said how honored she was when Harry Potter was a part of his family’s life and offered Burke more books. Besides, people are also offering to send Burke more books as gifts. For Burke, this experience, far more than gifts, will be what he treasures.
1. Why did Burke thank J. K. Rowling according to the text?| A．She guided him how to write a good story. |
| B．She encouraged him when he was in trouble. |
| C．Her books helped him through times of confusion. |
| D．Her books helped him improve his bond with his daughter. |
| A．He has found it interesting to read the series. | B．He was too old to understand the series better. |
| C．He has chosen a better way of reading the series. | D．He hopes to play a role in the drama in the future. |
| A．Useless. | B．Normal. | C．Valuable. | D．Boring. |
| A．J. K. Rowling chooses to help improve kids’ health. |
| B．J. K. Rowling gives a magical gift to a single father. |
| C．J. K. Rowling has a deep influence on others’ growth. |
| D．Burke comes to know J. K. Rowling through her series. |
8 . There’s a new AI bot: ChatGPT, and you’d better pay attention, even if you aren’t into artificial intelligence. The tool is an AI chatbot system that OpenAI released in November 2022 to show off and test what a very large, powerful AI system can achieve.
ChatGPT remembers the thread of your dialogue, using previous questions and answers to inform its next responses. It derives its answers from huge volumes of information on the Internet. ChatGPT is built on top of the OpenAI GPT-3 family of large language models and is fine-tuned (a method of transfer learning) using both supervised and reinforcement learning (监督和强化学习).
You can ask ChatGPT anything, like explaining physics, asking for birthday party ideas and getting programming help. Perhaps it’s not smart enough to replace all humans yet, but it can be creative, and its answers can sound downright authoritative. A few days after its launch, more than 1 million people were trying out ChatGPT. UBS analyst Lloyd Walmsley estimated in February 2023 that ChatGPT reached 100 million monthly users in January, accomplishing in 2 months what took TikTok about 9 months and Instagram two and a half years.
ChatGPT is free to use at the moment because it is still in its research phase. But when too many people hop onto the server, it overloads and can’t process your request. It just means you should try visiting the site at a later time when fewer people are trying to access it. If you want to skip the wait and have reliable access, there is an option for you. As of Feb. 1, 2023, OpenAI has a ChatGPT pro plan, ChatGPT Plus, which allows users to have general access even during peak times. This service does come at a cost of $20/month.
However, ChatGPT can not replace Google. ChatGPT is an artificial intelligence robot that provides solutions to your questions, but Google is a search engine in which you can search for as much information as possible. ChatGPT has limited knowledge due to its programming but Google has unlimited knowledge which is updated every day.
