21、When you go to the desert with David Strayer, a cognitive psychologist, don’t be surprised if he sticks electrodes to your head.
On the third day of a camping trip in Utah, Strayer explains the “three-day effect” to 22 psychology students. Our brains, he says, aren’t tireless machines; they are easily tired by our fast-paced, increasingly digital lives. But when we slow down, stop the busywork, and seek out natural surroundings, we not only feel refreshed but also improve our mental performance. Strayer has demonstrated as much with a group of participants, who scored 50 percent higher on creative problem-solving tasks after three days of wilderness backpacking.
Strayer’s hypothesis is that being in nature allows the prefrontal cortex, the brain’s command center, to rest and recover, like an overused muscle. Strayer has his students put my head into a sort of bathing cap with 12 electrodes in it. Wires from them will send my brain’s electrical signals to a recorder for analysis. Then I walk carefully to a grassy bank along the San Juan River, where I’m supposed to think of nothing in particular, just watch the wide water flow by. I haven’t looked at a computer or cell phone in days, and it’s easy to forget for a few moments that I ever had them.
A few months after our Utah trip, Strayer’s team sends me the results of my test, which shows my brain waves at a range of frequencies and confirms that the gentle beauty of the San Juan River succeeded in quieting my prefrontal cortex.
So far the other research subjects’ results also confirm Strayer’s hypothesis. But no study can offer a full explanation of the brain-on-nature experience; something mysterious will always remain, Strayer says, and perhaps that’s as it should be. “At the end of the day,” he says, “we come out in nature not because science says it does something to us but because of how it makes us feel.”

22、 If your friend says she feels relaxed, but you see that she closes her hands into fists, you may doubt her words. Robots, however, might believe her. Body language says a lot, but robots have great difficulty in observing tiny body movements and can miss important social signals as a result.
Researchers at Carnegie Mellon University developed a body-tracking system that might help solve this problem. The system called OpenPose can track body movement in real time. One important quality of the OpenPose system is that it can track not only a person's head, body, arms and legs but also his fingers. To do that, the researchers used a dome （圆顶状物）lined with 500 cameras, where they recorded body movements at different angles and then used those pictures to build a data set.
They then passed those pictures through a keypoint detector to identify and label specific body parts. The software also learns to connect the body parts with different people, so it knows, for example, that a particular person's hand will always be close to his or her upper arm. This makes it possible to track multiple people at once.
The pictures from the dome were recorded in 2D. But the researchers used 3D technology to help the system understand how each movement appears from different angles. With all of this data processed, the system can determine how the whole hand looks even if some fingers cannot be seen.
Now that the system has this data set to draw from, it can run with just one camera and one computer. It no longer requires the camera-lined dome to determine body poses, making the technology mobile and accessible.
The researchers say this technology could be used for interactions between humans and machines. It could play a huge role in VR （虚拟现实）experiences, allowing finer detection of the user's physical movement without any added hardware. It could also help with more natural interactions with a home robot. You could tell your robot to “pick that up"， and it could easily understand what you're pointing at. By interpreting your physical gestures, the robot may even learn to read emotions by tracking body language. So when you' re silently crying with your face in your hands because a robot has taken your job, it might offer you a tissue.
【1】What does the underlined words “this problem" in Paragraph 2 refer to?
A．Humans are addicted to technology.
B．Human-robot relationship is poor.
C．Robots show too much trust in humans.
D．Robots fail to interpret physical gestures.
【2】What do we know about OpenPose?
A．It tracks one person at a time.
B．It can track slight body movements.
C．It uses a dome to recognize people.
D．It can take 500 pictures in one second.
【3】What makes OpenPose easy to use?
A．The data set.
B．3D technology.
C．A powerful computer.
D．A camera-lined dome.
【4】What would be the best title for the text?
A．What robots are expected to do in the future?
B．Why is body language so important?
C．Robots learn to read body language.
D．Robots can and will change our lives.
23、Gwen Ifill was a famous African-American journalist who fought for social justice through her news stories. After she died in 2016, a student award was set up in her honor.
Ana Rodriguez, a 16-year-old student at Archie Williams High School, won the 2021 Gwen Ifill High School Student of the Year Award. She won due to her real passion for fighting fake news about COVID-19 vaccines, medical studies and other social media dramas.
Rodriguez said that fake news these days is often masked as real news, meaning teenagers and adults need to cultivate a certain type of skepticism before they either react to the news or spread it. “You need to double-check the sources and get a second opinion,” she said, “If you read about vaccines having some kind of aftermath, go and check another website.”
Archie Williams High School English teacher Matthew Leffel nominated (提名) Rodriguez for the award because of her enthusiasm and “purposefulness”. “Ana went very deep with her research,” Leffel said. “She was able to demonstrate the kind of media literacy (媒介素养) skills that we had intended to build.”
The project used a free public fact-checking website called Checkology. Students were required to write an argument on their chosen topic. Then they had to produce a podcast on “The Truth About …”. In Rodriguez’s case, for example, it was “The Truth About Scientific Racism”. Rodriguez also worked on several different topics, including the fake information of COVID-19 vaccines.
She and other students also made their arguments into booklets to hand out. They hoped to educate more people. Some of their other topics included 5G towers, climate change and surveillance (监控) technology.
“Ana was purposeful,” Leffel said. “It was clear she was not just doing it as a class assignment, but as something that had an important meaning for her life.”
【1】What does the underlined word “skepticism” probably mean?
A．Doubt.
B．Interest.
C．Curiosity.
D．Concern.
【2】Why did the author mention Leffel in the fourth paragraph?
A．To praise Ana’s writing skills.
B．To show Ana’s purpose.

D．To indicate Ana’s ability.
【3】Ana and other students put their arguments in booklets in order to________.
A．hand out for money
B．make people think critically
C．learn more knowledge
D．enlarge their topics
【4】According to Leffel, we can infer that________.
A．Ana does anything with strong purposes
B．Ana does a class assignment very carefully
C．Ana does run after her life meaning
D．Ana does everything for herself and others
24、Anyone with a kid is aware of the fact that kids have a really unusual sense of humor, but there’s no other way to put it. Sometimes it’s a non-funny situation that they find amusing. Whatever it is, you might be wondering what on earth they think is so funny. Up until recently, researchers weren’t sure what the timeline was of developing a sense of humor.
A group of researchers called the Early Humor Survey (EHS) aim to understand just that and help parents get a better understanding of their kids’ sense of humor. They surveyed a group of parents from the United States, United Kingdom, and Australia.
During the first year of their babies’ lives, parents observed the different ways their children appreciated humor and were even able to produce some humor on their own. More than 3/4ths of the parents found their babies laughing by the second month of their lives. By their first birthday, almost all parents reported that their kids were all laughing.
While babies don’t have a full understanding of humor, we are able to see when they’re smiling or if they’re happy. EHS authors were able to see that babies had the ability to appreciate humor before they are able to produce humor themselves.
According to Kids Health, children with a sense of humor are more optimistic, happier and are able to handle differences with others. They are also more well-liked by their peers and show a better handling of adversities of childhood, including bullying, or moving to a new town. Since parents are the biggest role models in children’s lives, it’s safe to say that they develop their sense of humor from interacting with their parents.
【1】What can we learn from Paragraph 1?
A．Children are born with a sense of humor.
B．Parents seek for the cause of kids’ humor.
C．Experts know when kids produce humor.
D．Kids’ sense of humor differs from adults’.

A．The two-month-old babies begin to laugh.
B．Parents interpret children’s humor properly.
C．Humor helps kids cope with tough problems.
D．Kids understand humor while appreciating it.
【3】What is the best title for the passage?
A．Kids’ Humor at a Very Early Stage
B．How Parents Care about Kids’ Growth
C．A New Discovery about Babies’ Humor
D．Why Humor Is Important in Kids’ Life
【4】What can be talked about following the last paragraph？
A．How to create kids’ humor stories.
B．How to develop kids’ sense of humor.
C．How to distinguish types of kids’ humor.
D．How to make an assessment of kids’ humor.
