4 . Why can’t penguins fly?

Even the very smallest penguin,the fairy penguin,weighs 1 kg,which is about as much as a herring gull (银鸥). But herring gulls have a 1.4-meterwingspan,compared with just 32 centimeters for the fairy penguin. Water is 784 times denser (密度较大的) than air,and around 62 million years ago,penguins began making adaptations for swimming underwater. Their bones are filled with heavy bone marrow (骨髓)rather than air and they have much larger stomachs for making long fishing trips away from the nest.

How do squirrels find buried nuts?

It was once thought that they just used their noses to sniff out buried nuts and that the majority were never actually located. But a study at Princeton University showed that squirrels actually have a good memory and can build a map of the route from one hidden nut to the next.

Why don’t horses have toes?

Early horses such as Hyracotherium, which lived 55 million years ago, did have toes, but they were much smaller animals. For taller animals, extra weight at the end of their legs has a much bigger influence on their speed. A recent study at Harvard University, the USA, found that one broad hoof (蹄) is almost as strong as many smaller toes, but much lighter.

Do animals have blood types?

Yes, they do! As long as the animals in question have blood (not all do)then they will have species-specific “blood groups”. As with humans, these groups are determined by the structure of the blood based on the presence or absence of antibodies along with the make-up of the proteins that sit on the outside of red blood cells.

Humans are usually one of four main blood types. Thirteen types have been identified for dogs, eight for horses and three for cats.

5 . Jeni Stepanek’s home is an attractive four-bedroomed house. Had it been a one-roomed small house, however, Jeni would still have bought it. The only thing that mattered when she moved in four years ago was its location. It is near the 26-acre park in Rockville, near Washington, DC, created in honor of her son Mattie.

The park has play spaces, but at its heart is a memorial peace garden with a life-size statue of Mattie and his dog Micah. “Every day, I sit at my window and see mothers go over to the statue with their children,” says Jeni. “It is a terrible thing for a parent to bury a child, but I do see how Mattie has touched the world.”

Jeni is a mother who has experienced more sadness than most of us could imagine. All four of her children were born with a genetic disorder (遗传性疾病). The first three died before the age of four. Mattie survived until three weeks before his 14th birthday. In his short lifetime, he had sold more than two million copies of his poetry collections and given encouraging speeches to thousands of followers. His heroes—Oprah Winfrey, poet Maya Angelou, former US president Jimmy Carter became his best friends. At his funeral Carter said, “My wife and I have known kings, queens and presidents, but the most extraordinary person whom I have ever known is Mattie Stepanek.”

In the years after Mattie died, Jeni had been writing about his short but meaningful life. “I didn’t want my sadness to flow onto the pages and nor did I want people to think I was hanging on to Mattie’s coat tails. But I knew in the end I would tell the story because I was the only one who lived it with him,” she said. Jeni’s now published book Messenger is a celebration of Mattie’s achievements that were beyond his years.

6 . Most people associate space with silence. But the story of how we came to understand the universe is just as much a story of listening as it is by looking. And yet despite this, hardly any of us has ever heard space. How many of you could describe the sound of a single planet or star?

And you may wonder: How do we know what these sounds are? How can we tell the difference between the sound of the sun and the sound of a pulsar (脉冲星)? Well, the answer is the science of radio astronomy. Radio astronomers study radio waves from space using sensitive antennas (天线) and receivers, which give them precise information about what an astronomical object is and where it is in our night sky. And just like the signals that we send and receive here on earth, we can convert these transmissions into sound using simple analog techniques (模拟技术). And therefore, it’s through listening that we’ve come to uncover some of the universe’s most important secrets—its scale, what it’s made of and even how old it is.

In 1876, Alexander Graham Bell worked with Thomas Watson on the invention of the telephone. A key part of their technical set-up was a half-mile long length of wire, which was thrown across the rooftops of several houses in Boston. The line carried the telephone signals that would later make Bell a household name. But like any long length of charged wire, it also inadvertently became an antenna. Thomas Watson spent hours listening to the strange crackles and hisses and whistles that his accidental antenna detected...

As he correctly guessed, some of these sounds were caused by activity on the surface of the sun. So while inventing the technology that would usher in the telecommunications revolution, Watson had discovered that the star at the center of our solar system emitted (发射) powerful radio waves.

1. How do the radio astronomers discover the universe’s secrets?

A．By watching.

C．Activities of the sun.	D．Radio waves.

4. From what kind of magazine can we read this text?

A．Society.

7 . The term “social distancing” has been at the center of public conversation for a while. But it’s not “social” distance we are trying to promote. It’s physical separation. In fact, preserving social ties — even at a distance — is essential for both mental and physical health. The results of an analytic review done in 2017 indicate that a lack of social support is on a par with smoking cigarettes as a risk factor for health.

Given this fact, how might we best stay connected to others while maintaining physical distance? Would we be better off e-mailing a friend? Making a phone call? Setting up a video chat? In our study, Nick Epley and I tested whether the media through which people interact affects their sense of connection — and how expectations about certain technologies impact the communication media they choose to use.

In our experiment, we asked participants to reconnect with someone that they hadn’t interacted with recently, either through e-mail or over the phone. Participants first made predictions about what it would be like to get in touch if they reached out in these two ways. They generally believed that they’d feel more connected when interacting via the phone than over e-mail. But they also predicted that talking on the phone could be more uncomfortable than sending an e-mail. Although these participants believed that talking encouraged stronger bonds, most of them said they’d rather send an e-mail than call the person up. Fears about awkwardness, it seems, push individuals toward text-based methods for communicating.

In the next part of the experiment, we had participants actually reconnect using one randomly determined mode of communication and then followed up with them after they had done so. We found that people do form meaningfully stronger bonds when interacting over the phone than over e-mail. Importantly, though, there was no difference in the amount of discomfort when reconnecting on the phone.

The next time you think about how best to connect, consider calling or setting up a video chat. Feelings of social connection are preferably facilitated by voice rather than a keyboard.

1. How does the author support his view on the importance of maintaining social ties?

A．By stating a deep-rooted tradition.	B．By citing a published report.
C．By sharing public opinions.	D．By presenting official documents.

2. What did the author and Epley’s study focus on?

A．How technologies impact means of communication.

B．How social media choices affect feelings of connection.

C．Why maintaining social separation is bad for mental health.

D．Why reconnecting with friends over the phone brings awkwardness.

3. What can we infer from the study results?

A．They changed the research objectives.	B．They provided insights for future studies.
C．They confirmed researchers’ expectations.	D．They contradicted participants’ predictions partly.

4. What can be concluded from the text?

A．For stronger bonds, talk instead of typing.

B．Keeping in touch is key to a lasting friendship.

C．Think before you consider contacting an old friend.

D．Text-based methods for communication cause discomfort.

8 . Eileen Gu got into extreme sports because of an overprotective mother. The older Gu hated seeing her daughter rush down California’s Tahoe ski slopes (斜坡), so she enrolled the 8-year-old in a free-skiing school, not knowing exactly what it involved. However, she was confident that anything would be safer than racing. Little did she know that she would one day watch her child perform death-defying flips, spins and jumps instead. And she never thought her daughter could be one of the sport’s top stars, with golds at X Games.

“I’ve probably been an adrenaline (肾上腺素) addict from day one,” Eileen Gu said. In February, that adrenaline took her all the way to the Winter Olympics in Beijing. It’s where her mom was born and a place she visited regularly during childhood. These are Gu’s first Games. She is just 18 years old.

In China, she is nicknamed “Snow Princess”. She is also academically gifted, graduating from high school a year early despite her punishing training schedule, and scoring 1,580 on her SAT and getting accepted into Stanford for 2022.

It’s a rapid rise that she hopes will inspire others. A speech, which she made to her seventh-grade class, urged her peers to “show the boys that girls are just as powerful as they are”. Naturally, you don’t soar to such heights without getting hurt. After cracking a finger and tearing a ligament (韧带) in her thumb, she was expected to miss last year’s world championships in Aspen. Gu certainly walks the talk: She instead chose to compete without ski poles and took home two gold medals and a bronze.

“Honestly, I’m a little nervous about getting the poles back, because I’ve gotten used to skiing without them.” she said after the event.

1. What caused Eileen Gu to be interested in extreme sports at first?

A．Her special talent.	B．Her strong interest.
C．Her experienced coach.	D．Her overprotective mother.

2. What did Eileen Gu’s mother do to help develop her daughter’s interest?

A．Take her daughter to skiing classes.	B．Watch sports program with her daughter.
C．Give her daughter some skiing equipment.	D．Travel around the world with her daughter.

3. What do we know about Eileen Gu from the text?

A．She has grown up in Beijing.	B．She has graduated from Stanford.
C．She has been to Beijing many times.	D．She has won gold medals in other Olympics.

4. In which column of the magazine could you probably find this text?

A．Fashion.

B．Technology.

C．Environment.
