Dịch bài

Trong một số trường hợp nhất định, cơ thể con người phải đối phó với các khí ở áp suất khí quyển lớn hơn bình thường. Chẳng hạn, áp suất khí tăng lên nhanh chóng trong khi lặn bằng thiết bị lặn bởi vì thiết bị thở cho phép thợ lặn ở dưới nước lâu hơn và lặn sâu hơn. Áp lực tác động lên cơ thể con người tăng lên 1 atmôtfe cho mỗi 10 mét chiều sâu trong nước biển, do đó ở 39 mét trong nước biển thợ lặn phải chịu áp lực khoảng 4 atmôtfe. Do đó tất cả các khí trong không khí hít thở của một thợ lặn bình thường ở độ cao 40 mét phải ở mức gấp năm lần áp suất thông thường của chúng. Nitơ, chiếm 80% không khí chúng ta hít vào, thường tạo ra cảm giác thoải mái khi chịu áp lực này. Ở độ sâu 5 ô, nitơ gây ra các triệu chứng giống như say rượu, được gọi là nhiễm độc nitơ. Nôn mửa nitơ dường như là kết quả từ một ảnh hưởng trực tiếp đến bộ não của một lượng lớn nitơ hòa tan trong máu. Những thợ lặn sâu thường ít nguy hiểm hơn nếu khi Heli được thay thế cho khí Nitơ, bởi vì dưới áp lực, khí heli không gây ra tác dụng gây mê tương tự.

Khi một thợ lặn lặn xuống, áp lực của nitơ lên phổi tăng lên. Nitơ sau đó phân tán từ phổi sang máu, và từ máu đến các mô cơ thể. Quá trình ngược lại xảy ra khi các thợ lặn trở lên mặt nước, áp suất nitơ trong phổi hạ xuống và nitơ khuếch tán từ mô vào máu, và từ máu vào phổi . Nếu như quay trở lại mặt nước quá nhanh, khí ni tơ trong các mô và máu không thể khuếch tán ra ngoài đủ nhanh chóng và bóng khí ni tơ sẽ hình thành. Nếu như quay trở lại mặt nước quá nhanh, khí ni tơ trong các mô và máu không thể khuếch tan ra ngoài đủ nhanh chóng và bóng khí ni tơ sẽ hình thành. Chúng sẽ gây ra những cơn đau khủng khiếp, đặc biệt là xung quanh các khớp xương.

Một biến chứng khác có thể xảy ra nếu hơi thở được giữ trong quá trình trở lên mặt nước. Trong quá trình nồi lên từ độ sâu 10 mét, lượng không khí trong phổi sẽ tăng lên gấp đôi vì áp lực khí tại bề mặt nước chỉ còn 1 nửa so với ở độ sâu 10 mét. Sự thay đổi về lượng khí có thể làm phổi sưng phồng, thậm chí là vỡ nát. Hiện tượng này gọi là thuyên tắc hơi.

Để tránh sự hiện tượng này, một thợ lặn phải đi nổi lên thật chậm, không bao giờ ở tốc độ vượt quá sự nổi lên của bong bóng khí thở ra, và phải thở ra khi lên.

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.

    The ruined temples of Angkor are perhaps one of the most impressive Seven Wonders of the World. Located in modern day Cambodia near Lake Tonle Sap, the largest freshwater lake in Asia, Angkor was the seat of power for the Khmer Empire for the ninth to the fifteenth century. The ruins of Angkor are documented as some of the most impressive ones in the world, rivaling the pyramids of Giza in Egypt. Why this mighty civilization died out is a question that archeologists are now only beginning to ponder. The answer, it turns out, may be linked with the availability of fresh water.

One possible explanation for the downfall of the Khmer Empire has to do with the inhabitant’s irrigation system. The temples and palaces of Angkor were constructed around a series of artificial reservoirs and canals which were annually flooded to capacity by the Mekong River. Once filled, they were used to irrigate the surrounding paddies and farmland during the course of the year. Farmers were completely dependent on the water for water crucial rice crop. Without consistent irrigation, the farmers would have been unable to maintain functional crop production.

Scientists speculate that toward the end of the Khmer Empire the hydraulic system of the reservoirs and canals broke down. The construction of hundreds of sandstone temples and palaces required an enormous amount of physical labor. In addition, as the capital of Khmer Empire, Angkor contained upwards of one hundred thousand people who resided in and around Angkor. In order to feed so many people, the local farmers were driven to grow food more quickly and more efficiently. After centuries of continual use, the irrigation system was pushed beyond its capacity. Soil erosion, nutrient depletion, and loss of water led to decrease in the food supply. With the less food available, the people of Angkor slowly began to migrate to other parts of Cambodia, thus leaving the marvelous city of Angkor to be swallowed by the jungle. Therefore, it is speculated that the Khmer Empire may have fallen victim to its own decrepit infrastructure.

The passage preceding most likely discusses ________.  

A. architecture of ancient Asian civilization 

B. religious practices of the people of Angkor

C. the form of government practiced by the Khmer Empire

D. the other six wonders of the world
