2 . Why do we talk the way we do? It might date back to when our ancestors left the jungle for the open plain. Between 5.3 million and 16 million years ago, Africa’s landscapes changed from thick, leafy forests to wide-open grasslands. This environmental change pushed our ancestors out of the trees and onto the ground. Along with all of the physical and behavioral changes this may have caused, researchers also believe it may have changed the way we speak.

“Open landscapes provide us with fewer objects to affect signal communication, meaning our voices can travel further compared with that in thick forests,” Charlotte Gannon, a researcher who studies language development, told Newsweek. “The move to these open spaces may have increased the effectiveness of our communication.”

By comparing the vocal calls of the orangutan (大猩猩) , Gannon and her team were able to establish how different calls could travel across different landscapes. In their study, the team played 487 calls from orangutans and measured their audibility (可听度) at set length over an overall distance of over 1,300 feet in the South African plain.

“Our results were surprising,” Gannon said, “The rule of sound spread suggests that lower-frequency (低频率) sounds (the grumphs) would have traveled further than higher-frequency sounds (the kiss squeaks). Our results actually found the opposite to this.” In these environmental settings, consonant (辅音)-like calls traveled a lot further than vowel (元音) -like calls. Actually, around 80 percent of consonant-based calls were audible at 1,300 feet, compared to only 20 percent of vowel-based calls.

Gannon said these results highlight the importance of studying living orangutan to learn about our species’ history. “We can view them as time machines that allow us to recreate key moments of our history so we can learn more about the development of our language,” Gannon said. “Despite their popularity in modern languages, consonants have often been forgotten when discussing speech development. Our research highlights not only their presence in ancient times but their importance to the development of language.”

3 . Njobati, a young woman from Cameroon, faced a challenging journey when she moved from her English-speaking area to a French-speaking area of the country to attend university. The sharp differences between these areas, once part of the British and French empires, made it difficult for her to fit in, which led her to examine her own identity—who she truly was.

Seeking guidance, she turned to her grandfather who also felt disconnected from his own culture. He expressed sadness about what the Nso had lost both culturally and materially, including Ngonnso statue. Ngonnso was the founder of Nso dating back to the 14th Century, whose statue was an important cultural symbol for the Nso. However, it was taken by the Germans in 1902 and has been housed in Berlin’s Ethnological Museum ever since.

Inspired by her grandfather’s desire and saddened by the loss of culture, Njobati made a promise to bring back the statue. She believed it would not only achieve her grandfather’s wish but connect her with her Nso heritage again.

Njobati did many researches about the statue and former unsuccessful attempts. She realized that restitution (归还) was actually about facing the colonial ( 殖民主义的) past. Njobati decided to try differently. To gather support online and offline, Njobati began a grassroots campaign. She organized meetings in community halls and churches, met people one-on-one, and used the power of social media.Through Twitter, she established contact with the Ethnological Museum.

Njobati’s tireless efforts paid off. She was told that a decision about Ngonnso statue was coming, which was an important moment for her.

“Finally, this is happening. Not just for me, but for the Nso people, and for Cameroon,” She cried. “This also lends a hand to other communities that are seeking justice for stolen culture relics.”

B．Her grandfather’s identity problem.

C．Her desire to reconnect with Nso culture.

7 . For lots of kids, toddlerhood (幼儿期) is an important time for friendship. Studies show that the earlier kids learn to form positive relationships, the better they are at relating to others as teenagers and adults. Playing together also helps these kids practice social behaviors, such as kindness, sharing, and cooperation.

Even so, how quickly your child develops into a social creature may also depend on his temperament(性格). Some toddler s are very social, but others are shy. In addition, the way that toddlers demonstrate that they like other children is markedly different from what adults think of as expressions of friendship. Research at Ohio State University in Columbus found that a toddler’s way of saying “I like you” during play is likely to come in the form of copying a friend’s behavior.

This seemingly unusual way of demonstrating fondness can result in unpleasant behavior. Regardless of how much they like a playmate, they may still grab his toys, refuse to share, and get bossy. But experts say that this is a normal and necessary part of friendship for kids this age. Through play experiences, toddlers learn social rules. That’s why it’s so important to take an active role in your toddler’s social encounters by setting limits and offering frequent reminders of what they are. When you establish these guidelines, explain the reasons behind them.

Begin by helping your child learn sympathy (“Ben is crying. What’s making him so sad?”), then suggest how he could resolve the problem (“Maybe he would feel better if you let him play the ball.”). When your child shares or shows empathy(同理心) toward a friend, praise him (“Ben stopped crying! You made him feel better.”).

Another way to encourage healthy social interaction is by encouraging kids to use words- not fists-to express how they feel. It’s also important to be mindful of how your child’s personality affects playtime. Kids are easy to get angry when they’re sleepy or hungry, so schedule playtime when they’re refreshed.

1. What does it indicate when toddlers copy their playmates’ behavior?

A．They are interested in acting.	B．They are shy with the strangers.
C．They are fond of their playmates.	D．They are tired of playing games.

2. What does the author suggest parents do for their kids?

C．Play together with them.	D．Help them understand social rules.

3. What is the function of the quoted statements in paragraph 4?

A．Giving examples.	B．Explaining concepts.
C．Providing evidence.	D．Making comparisons.

4. Which of the following is the best title for the text?

A．How Children Adapt to Changes	B．How to Be a Role Model for Children

9 . Atomic shapes are so simple that they can’t be broken down any further. Mathematicians are trying to turn to artificial intelligence (AI) for help to build a periodic table of these shapes, hoping it will assist in finding yet-unknown atomic shapes.

Tom Coates at Imperial College London and his colleagues are working to classify atomic shapes known as Fano varieties, which are so simple that they can’t be broken down into smaller components. Just as chemists arranged element s in the periodic table by their atomic weight and group to reveal new insights, the researchers hope that organizing these atomic shapes by their various properties will help in understanding them.

The team has given each atomic shape a sequence of numbers based on its features such as the number of holes it has or the extent to which it bends around itself. This acts as a bar code (条形码) to identify it. Coates and his colleagues have now created an AI that can predict certain properties of these shapes from their bar code numbers alone, with an accuracy of 98 percent.

The team member Alexander Kasprzyk at the University of Nottingham, UK, says that the AI has let the team organize atomic shapes in a way that begins to follow the periodic table, so that when you read from left to right, or up and down, there seem to be general patterns in the geometry (几何) of the shapes.

Graham Nib lo at the University of Southampton, UK, stresses that humans will still need to understand the results provided by AI and create proofs of these ideas. “AI has definitely got unbelievable abilities. But in the same way that telescopes (望远镜) don’t put astronomers out of work, AI doesn’t put mathematicians out of work,” he says. “It just gives us new backing that allows us to explore parts of the mathematical landscape that are out of reach.”

The team hopes to improve the model to the point where missing spaces in its periodic table could point to the existence of unknown shapes.

D．Threat.

4. What is the main idea of the text?
