Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 35 to 42.

Nature has always provided a stimulus for inventive minds. Early flying machines clearly were an attempt to emulate the freedom of birds. Architects and engineers have often consciously modeled buildings on forms found in nature. A more recent example of the inspiration given by nature is the invention of Velcro®. The inventor of this now common fastening device noticed that small burrs attached to his dog's coat grasped the hairs by means of tiny hooks. This led him to invent a synthetic fabric whose surfaces mimic the clasping properties of this natural seedpod.

Animals and plants have evolved solutions to the kinds of problems that often interest engineers and designers. Much current research in material science is concerned with actively examining the natural world, especially at the molecular level, for inspiration to develop materials with novel properties. This relatively new field of study is sometimes known as biomimetics, since it consciously attempts to mimic nature.

Researchers have investigated several interesting areas. For example, they have studied how the molecular structure of antler bone contributes to its amazing toughness, how the skin structure of a worm contributes to its ability to crawl, how the sea cucumber softens its skeleton and changes shape so that it can squeeze through tiny gaps in rocks, or what gives wood its high resistance to impact. These investigations have led to several breakthroughs in the development of composite materials with remarkable properties.

Predictions for future inventions that may be developed from these lines of research include so-called smart structures that design and repair themselves in a similar way to a variety of processes in the natural world. For example, engineers have envisaged bridges that would detect areas heavily stressed by vehicle movement or wind. The bridge structure would then automatically add or move material to the weak areas until the stress is reduced. The same principle might be used to repair damaged buildings. Other new materials that have been imagined are substances that would copy photosynthesis in green plants in order to create new energy sources. The potential impact of biomimetic research is so great that the twenty-first century may come to be known as the "Age of Materials."

 

As inferred from the passage, what would be the advantage of a product that mimics photosynthesis? 

A. It could be used to create green plants

B. It could help to meet future energy needs

Đáp án chính xác

C. It could be an aid in repairing green areas

Thông tin: Other new materials that have been imagined are substances that would copy photosynthesis in green plants in order to create new energy sources.

Tạm dịch: Các vật liệu mới khác đã được tưởng tượng là các chất liệu sao chép sự quang hợp trong cây xanh để tạo ra những nguồn năng lượng mới.

Dịch bài đọc:

Thiên nhiên luôn cung cấp kích thích cho trí óc sáng tạo của con người. Những cỗ máy có khả năng bay thời kỳ đầu rõ ràng là một nỗ lực để mô phỏng sự tự do của loài chim. Các kiến trúc sư và kỹ sư thường chủ tâm tạo ra các tòa nhà có hình mẫu từ các hình thái được tìm thấy trong tự nhiên. Một ví dụ gần đây hơn về cảm hứng được tạo ra bởi thiên nhiên là phát minh của Velcro®. Nhà phát minh của thiết bị cài chặt phổ biến này đã nhận thấy rằng các gờ nhỏ gắn vào cái áo cho con chó của anh ta đã mắc vào lông nó bằng những cái móc rất nhỏ. Điều này dẫn dắt anh ta phát minh ra một loại vải tổng hợp mà bề mặt của nó bắt chước những đặc tính bám, móc của vỏ quả đậu ngoài tự nhiên.

Động vật và thực vật đã phát triển các giải pháp đối với nhiều loại vấn đề mà thường hấp dẫn các kĩ sư và các nhà thiết kế. Nhiều nghiên cứu hiện tại trong khoa học vật liệu thì đang tích cực nghiên cứu thế giới tự nhiên, đặc biệt là ở cấp độ phân tử, để lấy cảm hứng phát triển những vật liệu có tính chất mới lạ. Cái lĩnh vực nghiên cứu tương đối mới này thì thỉnh thoảng được biết đến như là mô phỏng sinh học, bởi vì nó cố gắng mô phỏng tự nhiên có ý thức.

Các nhà nghiên cứu đã nghiên cứu một vài mảng thú vị. Ví dụ, họ đã nghiên cứu làm thế nào mà cấu trúc phân tử của xương gạc nai góp phần vào sự dẻo dai đáng kinh ngạc của nó, hay làm thế nào mà cấu trúc da của một con sâu góp phần vào khả năng bò của nó, hoặc làm thế nào mà hải sâm làm mềm bộ xương của mình và thay đổi hình dạng để mà nó có thể ép mình đi qua những khoảng trống nhỏ trong đá, hoặc cái gì đem đến cho gỗ khả năng chịu đựng va đập cao. Những nghiên cứu này đã dẫn đến những bước đột phá trong sự phát triển của các vật liệu kết hợp với những tính chất vượt trội.

Những phỏng đoán về các phát minh trong tương lai cái mà có thể được phát triển từ những bước nghiên cứu này bao gồm cái gọi là các cấu trúc thông minh – cấu trúc tự thiết kế và sửa chữa theo cách giống như các quá trình trong thế giới tự nhiên. Ví dụ, các kỹ sư đã dự tính những cây cầu mà sẽ phát hiện ra các khu vực bị áp lực nặng do sự di chuyển của phương tiện hoặc gió. Cấu trúc của cầu sẽ ngay lập tức thêm hoặc di chuyển chất liệu đến những khu vực yếu cho đến khi áp lực giảm xuống. Cùng nguyên lý như vậy có thể được sử dụng để sửa chữa các tòa nhà bị hư hại. Các vật liệu mới khác đã được tưởng tượng là các chất liệu sao chép sự quang hợp trong cây xanh để tạo ra những nguồn năng lượng mới. Ảnh hưởng tiềm năng của nghiên cứu mô phỏng sinh học thì lớn đến nỗi thế kỷ hai mươi mốt có thể được biết đến như là “Thời đại vật liệu”.

Câu 4:

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 30 to 34.

A leading question among anthropologists is: what exactly led to the development of human cities? Basically, modern humans have existed on earth for over 100,000 years. Yet it is only in the last 8,000 years that they have begun to gather in significant numbers and form cities. Prior to that period, humans existed in small family or tribal groups, generally consisting of fewer than 100 individuals. What, then, led humans to make the dramatic shift from living in small groups to living in large, organized cities? It seems that the development of cities required a particular set of circumstances.

First, it required a minimum population density. For much of their early history, humans existed only in small numbers. This is due to the fact that early humans relied on hunting and gathering wild foods for their survival. Even the most fertile land would only support a relatively small number of predators, so it was not until humans began to practice agriculture that they were able to gather in large enough numbers to form cities.

Furthermore, the development of a city could only be possible if a large number of people shared a common language, culture and religion. Without such unifying factors, a cooperative, peaceful existence among large numbers of people would have been impossible.

Finally, it seems that early humans needed to be faced with a large problem, which one small group of individuals could not solve on its own. Only when large-scale cooperation was needed to overcome a problem would humans come together to form cities

Which of the following is NOT needed for the development of a city?
