【題目】請閱讀下面文字及圖表，并按照要求用英語寫一篇150詞左右的文章。

Mandarin (普通話) is the common language in China, but each region has its own dialect (方言). For travelers, a familiar accent can refresh the memory of their hometown.

According to an official video by the Chinese Education Ministry’s Language Com mission, among the more than 130 languages spoken in China, 68 of them are spoken by less than 10,000 people; and 25 by under 1,000.

Hu Shuning, a dialect preservationist, said, “I think it is natural with a society’s development that a dominant language appears, but from a cultural aspect I think dialects are still important, because they reflect cultural diversity.”

“Mandarin can take you further, but your dialect tells you where you come from,” said Wang Han, a well-known TV host.

【題目】 A group of blue-faced birds step through the grass shoulder to shoulder, red eyes looking around. They look like middle schoolers seeking a cafeteria table at lunchtime. Perhaps they’re not so different.

A new study, led by Damien Farine, an ornithologist who studies collective behaviour, shows that the vulturine guineafowl of eastern Africa, like humans, have multilevel societies. In the past, scientists assumed such social structures required a lot of brainpower. But the pea-brained guineafowl are revealing the faults in that assumption.

These large birds wander across the landscape in packs, often walking so closely that their bodies touch. They may fight each other to maintain their strict hierarchies (等級制度), but at other times they engage in friendly behaviours like sharing food.

Suspecting the guineafowl might have a social structure, Dr. Farine and his colleagues began a thorough study of their society. For a whole year, they made daily observations of 441 birds. Coloured leg bands in unique combinations let researchers tell the black-and-blue birds apart. They also attached GPS devices to the backs of 58 birds, which let them see exactly where every group went, 24 hours a day.

The findings of the research suggest that the vulturine guineafowl have a multilevel society. There are groups within groups within the population as a whole. There even seem to be groups of friends within the small groups. This is the first time anyone has observed such a society in a bird.

And Dr. Farine emphasizes this particular bird’s tiny brain size: “They don’t only have small brains relative to mammals (哺乳動物), they also have quite small brains relative to other birds,” he said.

According to him, living in this kind of society might actually make it easier to keep track of the social order. For example, if groups are stable and a bird can identify just one or two individuals within a group, it knows which group it’s looking at — no need for a brain that can recognize every single animal. Multilevel societies also let animals adjust their group sizes based on whatever challenges they’re facing. Depending on what enemies or resources are around, it might make sense to travel in a combined group rather than a smaller one.

“Having a multilevel structure may not require having a large brain,” Dr. Farine said. There may be more birds and other animals out there that, although small-brained, have societies as many-leveled as our own.

【1】According to the passage, what inspired Dr. Farine to carry out the study?

A.The guineafowl’s social behaviour.

B.Previous assumptions about birds.

C.His interest in animal brainpower.

D.The faults in earlier research.

【2】What is Paragraph 4 mainly about?

A.The research subjects.B.The research methods.

C.The research findings.D.The research equipment.

【3】What can be learned from the passage?

A.Complex social systems can be a disadvantage to the guineafowl.

B.The guineafowl are good at recognizing individuals in a group.

C.Birds maintain social order by travelling in combined groups.

D.Small-brained animals can form multilevel societies.

【4】What is the main purpose of the passage?

A.To present the findings of a study of the guineafowl.

B.To explain the interaction patterns in multilevel societies.

C.To introduce a new approach to observing the guineafowl.

D.To uncover clues about how complex societies are formed.
