1 . African penguins live on the rocky coasts of South Africa, Namibia and nearby islands. Like other types of penguins, the birds have white feathers covering their chests and black feathers covering their backs. They form lifelong pair bonds with mates, but they nest in huge colonies — so, scientists wondered how the birds were able to identify their partners among the sea of black-and-white birds. They wondered if their chest spots had something to do with it. To test this theory, they studied 12 African penguins at a zoo and marine park near Rome called Zoomarine Italia.
In one test, they hung two life-size photographs of the African penguins. One showed a random member of the colony, while the other showed the test subject’s mate. The scientists recorded the birds’ interactions with the photos: How long did they spend looking at each one, as well as how much time did they spend standing near each photograph? The penguins spent more time gazing at the photo of their partners — about 23 seconds longer, on average — than looking at the other photo. They also stood next to the image of their beau s for twice as long. Then, the researchers covered up the heads of the birds in the photographs, leaving only their speckled bodies visible, and the penguins still lingered near their partners’ portraits.
In another experiment, the researchers hung up two photos of a bird’s mate — but, in one, they had digitally removed its spots. In this case, the penguin again spent more time looking at the photo with the dots.
Finally, the researchers posted two photographs of penguins with digitally removed spots — one of the test subject’s mate and the other of a random penguin from the colony. In this scenario, the penguins did not appear to recognize their partners. They spent roughly the same amount of time gazing at or standing near both photos.
Together, the results of these experiments suggest African penguins are zeroing in on their partners’ spots and using them like name tags, scientists say.
“Our results provide the first evidence of a specific visual cue responsible for spontaneous individual recognition by a bird and highlight the importance of considering all sensory modalities in the study of animal communication,” the researchers write in the paper.

7 . Last summer holiday, Aunt Emily took us to a safari park (野生动物园), not far from Liverpool.
I was very happy to go as I had never been to a safari park before. It’s a very interesting park, full of wild animals running freely.
When we got there, we bought our tickets and drove into the park. We were very excited at the thought of going to see the lions. But to get to the lions’ place we had to go through the monkeys’ land first. And that was an unforgettable experience because they climbed all over the car, ate apples and bananas, and threw all kinds of things at us. They seemed very unfriendly.
Anyway, we went on our way to the lions’ place where we had to lock ourselves in the car as we knew lions could be dangerous. A lion came up very close to us. Then it was on the bonnet (车盖). It looked calm but we felt terrified. Aunt Emily, who isn’t very brave, started to call for help. The kids started crying. Only my brother, George, stayed cool. I sounded the horn (喇叭) but nobody heard us.
In the end a guard arrived in his car, and the lion just got off our car and started smelling the guard’s hand as if nothing was the matter.

9 . I’m in the area of Noailles in Marseille, France’s second largest city and its main trade seaport. Some small shops sell vegetables, meat, and, it seems, all the spices of the Middle East. In addition to French, languages spoken on the busy streets include Arabic and African French. It all adds up to one of the most ethnically diverse cities in Europe.
Close to the downtown street, I discover an Algerian restaurant, whose owner makes his signature dish-couscous with barley, not the usual wheat, using a recipe that hasn’t changed since the 1920s. Couscous is an necessary part of Marseille culture. The dish was added to the UNESCO’s Lists of Intangible Cultural Heritage in 2020.
To be honest, before I travelled here, couscous had not been the first meal that came to mind when I thought of Marseille. It was bouillabaisse, the rich soup with olive oil, garlic and saffron. I imagined enjoying it at a small portside cafe. This was clearly a romantic fantasy. For one thing, there are no small cafes at historic city. For another, the restaurants do serve bouillabaisse, but when I see the price at one place I am shocked: 69 euros! No bowl of soup should cost that much.
I give up and end up two streets away from the old harbor in a new restaurant, Ourea. For 28 euros, Chef Matthieu Roche serves a three-course lunch that includes tuna steaks and couscous.
More and more young, talented people are discovering that Marseille is an ideal place to live. There is also a growing number of Parisians moving here every year. Tired of the rush and expense of life in larger cities, the newcomers come looking for the more relaxed Mediterranean way of life.
Walking through these contrasting neighborhoods of Marseille. I think about the distinct communities here living in the same neighborhoods — together, side by side, but not mixed. They may also feel they are Marseillais first regardless of nationalities.
1. Which word can best describe Marseille according to the first paragraph?A.Remote. | B.Commercial. | C.Industrial. | D.Inland. |
A.The unreasonable charge. | B.The unbearable flavor. |
C.The unsatisfying service. | D.The noisy atmosphere. |
A.To make a fortune. | B.To experience a dish. |
C.To learn a language. | D.To live a leisurely life. |
A.Fashion. | B.Food. | C.Trade. | D.Travel. |
10 . “Anyone knows single parents who can’t afford to get their child’s hair done for school? I will braid (编辫子) it for free!”Brittany Starks wrote on a Facebook post.
She decided to offer her hair braiding services after a family friend delivered backpacks full of school supplies, clothing and shoes for Cayden and Ceniyah in early August. “At the time, I didn’t have anything for my kids to start school,” said Starks, who is in between homes and staying with her mother. “It meant so much to me.”
The unexpected gift made a big difference to Starks and her children, and it motivated her to pay it forward. Starks, who works two receptionist jobs, also braids hair part-time. “The hair-braiding process involves washing, blow-drying, and finally dividing the hair into small sections and braiding it. It also requires multiple supplies — including combs, brushes, hair jam and additional pieces of hair to weave in. It costs anywhere from $150 to $400 at a salon (美发厅), depending on the style,” Stacks explained. “But it can last for months and is a huge timesaver in the mornings.”
When she wrote the Facebook post, she assumed only a handful of people would reach out,but before she knew it, she had 35 appointments booked. Her Facebook inbox was suddenly full of messages from single parents, whose stories of hardship and financial challenges mirrored her own.
“There’s a huge need for this. I could really relate to a lot of the women who reached out, and it made me realize that what I was doing was really important,” said Stacks. “What got me the most was seeing the kids smile.” Given that there was less than two weeks before the start of school, Starks knew she needed to enlist help.
1. What got Brittany Starks to offer her hair braiding service?A.A post on Facebook. | B.Her friend’s timely help. |
C.Her mother’s advice. | D.A trip to her kids’ school. |
A.It’s a bit dear. | B.It’s time-wasting. |
C.It’s an easy job. | D.It’s a mother’s duty. |
A.Rather disturbing. | B.Beyond expectation. |
C.Far from satisfactory. | D.Very disappointing. |
A.She is single with one child. | B.She is ambitious and arbitrary. |
