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.

I am a proud mother of three children, my last little one being delivered in the middle of this pandemic (疫情). She was born in August and her name is Aida.
Shortly after having Aida, my mother-in-law Ann showed me something she learned from her friend’s mother in an art class she attended weekly, She had showed me how to knit (编织) a scarf.
I spent a lot of time breastfeeding my sweet little girl, so I had some extra time to do something with my hands throughout the day. I enjoyed making the scarf so I purchased tons of yarn (线) since it was winter. I wanted to make scarves for my three children as Christmas gifts.
There was a new family that moved in down the street. The only daughter of the family was Jane, a shy girl, aged 14, the same age of my oldest son David. It seemed that she came from a financially disadvantaged family, for she always wore old clothes. Worse still, in such cold days, she had no more clothes to wear and trembled with cold.
Due to the pandemic, society was thrown into crisis mode. Schools were closed, food supplies and deliveries were suspended and children were stuck at home. In such discouraging time, however, they became good companions, talking and playing at home or around the houses.
It was dreadfully cold this winter. Every time David came back from outside, with red face, he always cried, “Mum, it is freezing outside!” Then, he came over to see whether I finished the scarf. I could tell how impatient he was to wear my scarf sooner! I had to speed the project to satisfy his expectation. But David comforted me by saying he could wait a few days. What a kind and considerate boy he was! Then my great art project finally was accomplished on the morning ahead of Christmas.

Jenny was the only child in her family. She had a quarrel (吵架) with her mother that afternoon and she ran out of the house angrily. She couldn’t help weeping sorrowfully when she thought of the scolding from her mother. Having wandered aimlessly in the street for hours, she felt a little hungry and wished for something to eat. She stood beside a stand (货摊) for a while, watching the middle-aged seller busy doing his business. However, with no money in hand, she gave a sigh and had to leave.
The seller behind the stand noticed the young girl and asked, “Hey, girl, you want to have the noodles?”
“Oh, yes, but I don’t have money on me.” she replied.
“That’s nothing. I’ll treat you today,” said the man, “Come in.”
The seller brought her a bowl of noodles, whose smell was so attractive. As she was eating, Jenny cried silently.
“What is it?” asked the man kindly.
“Nothing. Actually, I was just touched by your kindness!” said Jenny as she wiped her tears. “Even a stranger on the street will give me a bowl of noodles, while my mother drove me out of the house. She showed no care for me. She is so merciless compared to a stranger!”
Hearing the words, the seller smiled, “Girl, do you really think so? I only gave you a bowl of noodles and you thanked me a lot. But it is your mother who has raised you since you were a baby. Can you remember the times she cooked for you? Have you expressed your gratitude to her?”
Jenny sat there, speechless and numb with shock: she remembered her mother’s familiar face and weathered hands. “Why didn’t I think of that? A bowl of noodles from a stranger made me feel grateful. Why haven’t I thanked my mum for what she has done for me?”
On the way home. Jenny made up her mind to make an apology to her mother for her rudeness as soon as she arrived home.

9 . I’m interested in the Renaissance (文艺复兴), so I like visiting ancient Italian cities. Ferrara is called City of the Renaissance. When I learned about this city on the Internet, I decided to pay a visit to it.
The city has a certain charm, but I find it isn’t as great as other Italian cities like Verona, let alone Venice or Rome. The Michelin Green Guide gives it two stars, which is right.
I first visited the city centre. The Cathedral and Castello Estense are at the heart of the city. Both have striking appearances. I visited the Cathedral first. Castello Estense is also worth visiting, which owes its name to the powerful Este family. It was built with bricks and surrounded by a moat (护城河). At the lower levels, the history of the city and the Este family are told through displays, and in another part the ceilings are shown through mirrors on the ground.
In the north, we can appreciate the Renaissance extension of the town, with straight streets and monumental houses. The famous Palazzo dei Diamanti lies here. When I was visiting it, it started to rain, so after taking a few photos quickly, I cut my visit there short. It had been raining for a few days. When the rain ceased, I went to visit the historical centre and the Renaissance buildings.
After leaving there, I visited several other interesting places such as palaces and the narrow streets of the downtown. After four hours in Ferrara I left by train to Mantua. There I had a much better time.

10 . While scientists have many ideas, they are not certain why humans yawn(打哈欠). Still, there is one thing experts know—yawns seem to be contagious(传染)!
Have you ever caught a yawn from someone else? Most people have. In fact, a person is six times more likely to yawn after seeing someone else do so. Experts have done many studies into why yawns seem to pass from person to person. As a result, they have a few theories(理论) for the reason behind it.
One possible explanation has something to do with social mirroring, which is caused by mirror neurons(镜像神经元) in the brain. These mirror neurons help the brain notice useful behavior of others and then copy it. When one person sees another yawn, his mirror neurons observe the action and consider it to be beneficial. That may cause him to yawn, too.
Another popular theory is that yawns are contagious because of social relationships. Being social creatures, humans form friendships, families and live together in groups. That’s why many people mirror others, such as smiling when another person smiles. Yawning may be just another example of this. In fact, research has shown that one is most likely to catch yawns from another person if the two share a social relationship.
The answer could even be that yawns aren’t truly contagious at all. Instead, people yawn together simply because they’re in the same environment. Experts say many things may cause yawning, including temperature and time of day. Whatever the explanation is, experts do know that contagious yawns aren’t limited to humans. One study found that lions in South Africa also caught each other’s yawns.

C.Hard to understand. | D.Easy to copy. |
A.Those who yawn a lot. | B.Those who like smiling. |
C.Those closely connected with them. | D.Those sharing the same interest with them. |

C.Other examples of animals yawning together. |
