Early peoples had no need of engineering works to supply their water. Hunters and nomads camped near natural sources of fresh water, and populations were so sparse that pollution of the water supply was not a serious problem. After community life developed and agricultural villages became urban centers, the problem of supplying water became important for inhabitants of a city, as well as for irrigation of the farms surrounding the city. Irrigation works were known in prehistoric times, and before 2000 BC the rulers of Babylonia and Egypt constructed systems of dams and canals to impound the flood waters of the Euphrates and Nile rivers, controlling floods and providing irrigation water throughout the dry season. Such irrigation canals also supplied water for domestic purposes. The first people to consider the sanitation of their water supply were the ancient Romans, who constructed a vast system of aqueducts to bring the clean waters of the Apennine Mountains into the city and built basins and filters along these mains to ensure the clarity of the water. The construction of such extensive water-supply systems declined when the Roman Empire disintegrated, and for several centuries local springs and wells formed the main source of domestic and industrial water.

The invention of the force pump in England in the middle of the 16th century greatly extended the possibilities of development of water-supply systems. In London, the first pumping waterworks was completed in 1562; it pumped river water to a reservoir about 37 m above the level of the River Thames and from the reservoir the water was distributed by gravity, through lead pipes, to buildings in the vicinity. Increased per-capita demand has coincided with water shortages in many countries. Southeast England, for example, receives only 14 per cent of Britain's rainfall, has30 per cent of its population, and has experienced declining winter rainfall since the 1980s.

In recent years a great deal of interest has been shown in the conversion of seawater to fresh water to provide drinking water for very dry areas, such as the Middle East. Several different processes, including distillation, electrodialysis, reverse osmosis, and direct-freeze evaporation, have been developed for this purpose. Some of these processes have been used in large facilities in the United States. Although these processes are successful, the cost of treating seawater is much higher than that for treating fresh water.

Tạm dịch: Người đầu tiên cân nhắc tới việc đảm bảo vệ sinh cho việc cung cấp nước chính là những người La Mã cổ

Dịch bài đọc:

Loài người thuở sơ khai không cần đến các công trình với mục đích cung cấp nước. Thợ săn và du mục thường cắm trại ở gần các nguồn nước sạch tự nhiên và dân cư thì quá thưa thớt để việc cung cấp nước trở thành 1 vấn đề cấp thiết. Sau khi cuộc sống cộng đồng phát triển và các ngôi làng nông nghiệp trở thành các trung tâm đô thị thì vấn đề cung cấp nước đã trở nên quan trọng đối với các cư dân thành thị cũng như là việc tưới tiêu cho các nông trại ở xung quanh thành phố. Công việc tưới tiêu đã được biết tới từ thời tiền sử và trước năm 2000 trước Công nguyên, nhà thống trị đế chế Babylon và Ai Cập đã cho xây dựng các hệ thống đập và kênh rạch để ngăn nước lũ từ sông Euphrates và sông Nile, qua đó kiểm soát lũ lụt và cung cấp nước phục vụ cho công cuộc tưới tiêu vào mùa khô. Nước từ các kênh rạch đồng thời cũng được cung cấp để phục vụ cho mục đích dân sinh. Người đầu tiên cân nhắc tới việc đảm bảo vệ sinh cho việc cung cấp nước chính là những người La Mã cổ, họ đã cho xây dựng 1 hệ thống thủy điện cỡ lớn để dẫn nước sạch từ dãy Apennine xuống các thành phố và cho xây dựng thêm các lưu vực và bộ lọc chạy dọc theo các ống dẫn để đảm bảo độ sạch của nước. Việc xây dựng các hệ thống cung cấp nước rộng lớn như vậy đã suy tàn khi mà Đế chế La Mã sụp đổ, và trong nhiều thế kỷ, nguồn nước chủ yếu là được lấy từ các suối và giếng để phục vụ mục đích dân sinh và công nghiệp.

Việc phát minh ra máy bơm ở Anh vào giữa thế kỷ 16 đã mở rộng đáng kể tiềm năng phát triển các hệ thống cấp nước. Ở London, máy bơm nước đầu tiên được hoàn thành vào năm 1562, nó bơm nước sông Thames vào hồ chứa cao hơn khoảng 37 m so với mực nước sông và từ hồ chứa đó, nước được phân bổ đi bằng cách hút, rồi đi qua các đường ống dẫn đến các tòa nhà trong những vùng lân cận.

Nhu cầu của số bình quân đầu người tăng cao khiến cho sự thiếu hụt nước xảy ra trên phạm vi nhiều quốc gia. Khu vực phía Đông Nam nước Anh là 1 ví dụ, trong khi chỉ nhận được 14% trên tổng lượng mưa nước Anh nhưng lại chứa tới 30% tổng số dân trên toàn quốc, và có lượng mưa mùa đông bị giảm đi từ những năm 1830. Trong những năm gần đây, có rất nhiều sự quan tâm dành cho công cuộc biến nước biển thành nước sạch để phục vụ cho các vùng hạn hán, chẳng hạn như Trung Đông. Trong đó có một vài quá trình bao gồm trưng cất, thẩm tách bằng điện, thẩm thấu ngược, bốc hơi đã được phát triển để phục vụ cho mục đích này. Một số quá trình này đã được sử dụng trong các cơ sở lớn ở Hoa Kỳ. Nhưng mặc dù có thành công đi chăng nữa thì chi phí cho việc xử lí nước biển vẫn cao hơn rất nhiều so với chi phí xử lí nước sạch.

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

Reading to oneself is a modern activity which was almost unknown to the scholars of the classical and medieval worlds, while during the fifteenth century the term “reading” undoubtedly meant reading aloud. Only during the nineteenth century did silent reading become commonplace.

One should be wary, however, of assuming that silent reading came about simply because reading aloud was a distraction to others. Examinations of factors related to the historical development of silent reading have revealed that it became the usual mode of reading for most adults mainly because the tasks themselves changed in character.

The last century saw a steady gradual increase in literacy and thus in the number of readers. As the number of readers increased, the number of potential listeners declined and thus there was some reduction in the need to read aloud. As reading for the benefit of listeners grew less common, so came the flourishing of reading as a private activity in such public places as libraries, railway carriages and offices, where reading aloud would cause distraction to other readers. Towards the end of the century, there was still considerable argument over whether books should be used for information or treated respectfully and over whether the reading of materials such as newspapers was in some way mentally weakening. Indeed, this argument remains with us still in education. However, whateverits virtues, the old shared literacy culture had gone and was replaced by the printed mass media on the one hand and by books and periodicals for a specialised readership on the other.

By the end of the twentieth century, students were being recommended to adopt attitudes to books and to use reading skills which were inappropriate, if not impossible, for the oral reader. The social, cultural and technological changes in the century had greatly altered what the term “reading” implied.

The development of silent reading during the last century indicated ______.

A. an increase in the average age of readers

B. an increase in the number of books

C. a change in the nature of reading

D. a change in the status of literate people

A. sự gia tăng tuổi trung bình của độc giả

B. sự gia tăng số lượng sách

C. một sự thay đổi trong bản chất của việc đọc

D. một sự thay đổi về địa vị của những người biết chữ

Dẫn chứng: Examinations of factors related to the historical development of silent reading have revealed that it became the usual mode of reading for most adults mainly because the tasks themselves changed in character.

Tạm dịch: Việc kiểm tra các yếu tố liên quan đến sự phát triển lịch sử của việc đọc thầm đã tiết lộ rằng nó trở thành chế độ đọc thông thường đối với hầu hết người lớn chủ yếu là do bản thân các nhiệm vụ đã thay đổi bản chất.
