Money

The ancestor of the monetary system is of course the barter system. A farmer could trade his produce for the fish obtained by a fisherman or the cloth produced by a weaver. Even today the barter system tends to come back into style in places suffering from social breakdown, or as an informal sideline activity in more harmonious lands. However, trying to reach agreement over the relative value of different things tends to be time-consuming and vexing, and so societies tended to converge towards a common medium of exchange. Pacific islanders used shells; Aztecs used cacao beans, the main ingredient of chocolate. Livestock was common among herding cultures; slaves were sometimes used, too, but they were much harder to control than cattle and so not as popular; and many cultures used salt, including the Romans for a time- hence, the modern term "salary". Incidentally, after World War II cigarettes were used as a medium of exchange in many countries then in very poor condition, and it is said that in Italy “penny candy” was commonly used as “small change” even into the 1970s.

The medium that gradually gained widespread acceptance was precious metals such as gold and silver. Coins are said to have been invented by the Lydians, a people of Asia Minor, sometime after 640 BC. They used stamped ingots of "electrum", a naturally occurring amalgam of silver and gold. The scheme was refined by King Croesus, ruler of Lydia from 560 to 546 BCE, who introduced coins of true gold. He is still identified with wealth in the expression "rich as Croesus". The introduction of coinage was a great boon for traders, simplifying transactions and allowing them to be conducted more smoothly over long distances.

[1] Coinage also helped support far-flung empires; the Roman Empire was built on silver and gold coins, as well as military victories. As the empire expanded, the expenditures of the state led to the debasement of the coins, beginning with an act of the Emperor Nero in 64 A.D. By the end of his reign, the silver content of Roman coins had shrunk by 10%. [2] Other emperors followed his example, and over 200 years from the start of the process, the content shrank to 5%. The coins’ buying power fell accordingly.

[3] Coins are still with us, though they are now little more than tokens made of non-precious metals. [4] Few countries still use silver or gold coins as anything other than collector's items.

A. advantage

Một số lượng lớn các phát minh phải trải qua nhiều năm khó khăn nghiên cứu và phát triển trước khi chúng được hoàn thiện. Ví dụ, Thomas Edison đã phải thực hiện hơn 1.000 nỗ lực để phát minh ra bóng đèn sợi đốt để dẫn tới thành công. Lịch sử có rất nhiều câu chuyện của những con người đầy nghị lực khác, vấp ngã, thất bại nhiều lần trước khi họ thành công. Tuy nhiên, một số phát minh thì không phải trải qua những giai đoạn khó khăn, mà chỉ đơn giản là do tai nạn tạo ra.

Trong hầu hết các trường hợp đó, khi nhà phát minh vô tình phát minh ra thứ gì đó, thực ra họ đã cố tạo ra thứ gì đó khác. Ví dụ, trong những năm 1930, nhà hóa học Roy Plunkett đã cố gắng tạo ra một chất mới có thể được sử dụng để làm lạnh các vật phẩm. Ông trộn lẫn một số hóa chất với nhau. Sau đó, ông đặt chúng vào một bình chứa áp lực và làm mát hỗn hợp. Vào thời điểm thí nghiệm của ông ấy hoàn tất, ông ấy đã có một phát minh mới. Nó không phải là một chất mới có thể được sử dụng để làm lạnh. Thay vào đó, ông đã phát minh ra Teflon, ngày nay được sử dụng phổ biến nhất để sản xuất chảo và chảo không dính. Tương tự như vậy, nhiều thập kỷ trước đó, John Pemberton là một dược sĩ ở Atlanta, Georgia. Anh đang cố gắng tạo ra một loại thuốc bổ mà mọi người có thể sử dụng bất cứ khi nào họ bị đau đầu. Trong khi anh không thành công trong nỗ lực đó, anh đã xoay xở để phát minh ra Coca-Cola, loại nước ngọt có ga nổi tiếng thế giới.

Các nhà khoa học cũng đã vô tình khám phá ra những phát hiện quan trọng khi họ tiến hành các thí nghiệm. Năm 1928, Alexander Fleming phát hiện penicillin, một loại kháng sinh, theo cách này. Ông đã phát hiện một số nấm mốc đang phát triển trong một món ăn với một số vi khuẩn. Ông nhận thấy rằng vi khuẩn dường như tránh nấm mốc. Khi ông điều tra thêm, ông đã xác định một số tính chất hữu ích của penicillin, đã cứu hàng triệu mạng sống trong vài thập kỷ qua. Tương tự như vậy, vào năm 1946, nhà khoa học Percy Spencer đã tiến hành một thí nghiệm với vi sóng. Anh ta có một thanh kẹo trong túi, và anh nhận thấy nó đột nhiên tan chảy. Anh ta điều tra và tìm hiểu lý do tại sao điều đó lại xảy ra. Ngay sau đó, ông đã chế tạo một thiết bị có thể sử dụng vi sóng để hâm nóng thức ăn.

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 44 to 55.

         Panel painting, common in thirteenth- and fourteenth-century Europe, involved a painstaking, laborious process. Wooden planks were joined, covered with gesso to prepare the surface for painting, and then polished smooth with special tools. On this perfect surface, the artist would sketch a composition with chalk, refine it with inks, and then begin the deliberate process of applying thin layers of egg tempera paint (egg yolk in which pigments are suspended) with small brushes. The successive layering of these meticulously applied paints produced the final translucent colors.

         Backgrounds of gold were made by carefully applying sheets of gold leaf, and then embellishing of decorating the gold leaf by punching it with a metal rod on which a pattern had been embossed. Every step in the process was slow and deliberate. The quick-drying tempera demanded that the artist know exactly where each stroke be placed before the brush met the panel, and it required the use of fine brushes. It was, therefore, an ideal technique for emphasizing the hard linear edges and pure, fine areas of color that were so much a part of the overall aesthetic of the time. The notion that an artist could or would dash off an idea in a fit of spontaneous inspiration was completely alien to these deliberately produced works.

         Furthermore, making these paintings was so time-consuming that it demanded assistance. All such work was done by collective enterprise in the workshops. The painter or master who is credited with having created the painting may have designed the work and overseen its production, but it is highly unlikely that the artist’s hand applied every stroke of the brush. More likely, numerous assistants, who had been trained to imitate the artist’s style, applied the paint. The carpenter’s shop probably provided the frame and perhaps supplied the panel, and yet another shop supplied the gold. Thus, not only many hands, but also many shops were involved in the final product.

         In spite of problems with their condition, restoration, and preservation, many panel paintings have survived, and today many of them are housed in museum collections. 

 

The “collective enterprise” mentioned includes all of the following EXCEPT ______.

A. supplying the gold leaf 

B. applying the paint

C. selling the painting

D. building the panels
