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 38 to 45. 

The oceans are so vast and deep that until fairly recently, it was widely assumed that no matter how trash and chemicals humans dumped into them, the effects would be negligible. Proponents of dumping in the oceans even had a catchphrase: "The solution to pollution is dilution." 

Today, we need look no further than the New Jersey–size dead zone that forms each summer in the Mississippi River Delta, or the thousand–mile–wide swath of decomposing plastic in the northern Pacific

Ocean to see that this "dilution" policy has helped place a once flourishing ocean ecosystem on the brink of collapse. 

There is evidence that the oceans have suffered at the hands of mankind for millennia. But recent studies show that degradation, particularly of shoreline areas, has accelerated dramatically in the past three centuries as industrial discharge and run–off from farms and coastal cities have increased. 

Pollution is the introduction of harmful contaminants that are outside the norm for a given ecosystem. Common man–made pollutants reaching the oceans include pesticides, herbicides, chemical fertilizers, detergents, oil, sewage, plastics, and other solids. Many of these pollutants collect at the ocean's depths, where they are consumed by small marine organisms and introduced into the global food chain. 

Many ocean pollutants are released into the environment far upstream from coastlines. Nitrogen–rich fertilizers applied by farmers inland, for example, end up in local streams, rivers, and groundwater and are eventually deposited in estuaries, bays, and deltas. These excess nutrients can spawn massive blooms of algae that rob the water of oxygen, leaving areas where little or no marine life can exist. 

Solid wastes like bags, foam, and other items dumped into the oceans from land or by ships at sea are frequently consumed, with often fatal effects, by marine mammals, fish, and birds that mistake them for food. Discarded fishing nets drift for many years, ensnaring fish and mammals. In certain regions, ocean currents corral trillions of decomposing plastic items and other trash into gigantic, swirling garbage patches. One in the North Pacific, known as the Pacific Trash Vortex, is estimated to be the size of Texas. 

Pollution is not always physical. In large bodies of water, sound waves can carry undiminished for miles. The increased presence of loud or persistent sounds from ships, sonar devices, oil rigs, and even from natural sources like earthquakes can disrupt the migration, communication, and reproduction patterns of many marine animals, particularly aquatic mammals like whales and dolphins.

Giải thích: 

Từ “spawn” ở đoạn 5 có thể thay thế bởi ____. 

A. sản xuất B. xuất hiện C. ngăn chặn D. giới hạn

Thông tin: These excess nutrients can spawn massive blooms of algae that rob the water of oxygen, leaving areas where little or no marine life can exist. 

Tạm dịch: Những chất dinh dưỡng dư thừa này có thể sinh ra những bông tảo khổng lồ cướp đi nước oxy, để lại những khu vực có ít hoặc không có sinh vật biển có thể tồn tại. 

Chọn A

Dịch bài đọc: 

Các đại dương rộng lớn và sâu thẳm đến mức gần đây, người ta cho rằng bất kể rác thải và hóa chất của con người đổ vào chúng như thế nào, các tác động sẽ không đáng kể. Những người ủng hộ việc bán phá giá trong các đại dương thậm chí đã có một câu khẩu hiệu: "Giải pháp cho ô nhiễm là pha loãng". 

Ngày nay, chúng ta không cần tìm đâu xa ngoài vùng chết có kích thước New Jersey hình thành mỗi mùa hè ở đồng bằng sông Mississippi, hay dải phân hủy nhựa rộng hàng ngàn dặm ở phía bắc Thái Bình Dương để thấy rằng chính sách "pha loãng" này có đã giúp đặt một hệ sinh thái đại dương từng hưng thịnh trên bờ vực sụp đổ. 

Có bằng chứng cho thấy các đại dương đã phải chịu đựng dưới bàn tay của nhân loại trong nhiều thiên niên kỷ. Nhưng các nghiên cứu gần đây cho thấy sự xuống cấp, đặc biệt là các khu vực bờ biển, đã tăng tốc đáng kể trong ba thế kỷ qua khi xả thải công nghiệp và thoát khỏi các trang trại và thành phố ven biển đã tăng lên. 

Ô nhiễm là sự ra đời của các chất gây ô nhiễm có hại nằm ngoài định mức cho một hệ sinh thái nhất định. Các chất gây ô nhiễm nhân tạo phổ biến đến các đại dương bao gồm thuốc trừ sâu, thuốc diệt cỏ, phân bón hóa học, chất tẩy rửa, dầu, nước thải, nhựa và các chất rắn khác. Nhiều chất gây ô nhiễm này thu thập ở độ sâu của đại dương, nơi chúng được các sinh vật biển nhỏ tiêu thụ và đưa vào chuỗi thức ăn toàn cầu. 

Nhiều chất ô nhiễm đại dương được thải ra môi trường ở thượng nguồn từ bờ biển. Phân bón giàu nitơ được áp dụng bởi nông dân trong đất liền, ví dụ, cuối cùng ở các dòng suối, sông và nước ngầm địa phương và cuối cùng được lắng đọng ở các cửa sông, vịnh và đồng bằng châu thổ. Những chất dinh dưỡng dư thừa này có thể sinh ra những bông tảo khổng lồ cướp đi nước oxy, để lại những khu vực có ít hoặc không có sinh vật biển có thể tồn tại. 

Các chất thải rắn như túi, bọt và các vật phẩm khác đổ xuống đại dương từ đất liền hoặc tàu trên biển thường được tiêu thụ, với các tác động thường gây tử vong, bởi các động vật có vú biển, cá và chim nhầm chúng với thức ăn. Vứt bỏ lưới đánh cá trôi dạt trong nhiều năm, cá và động vật có vú. Ở một số khu vực nhất định, dòng hải lưu hàng nghìn tỷ phân hủy các mặt hàng nhựa và rác khác thành những mảng rác khổng lồ, xoáy. Một ở Bắc Thái Bình Dương, được gọi là Vortex Thái Bình Dương, được ước tính là kích thước của Texas. 

Ô nhiễm không phải lúc nào cũng là vật chất. Trong các cơ quan lớn của nước, sóng âm có thể mang không hề suy giảm hàng dặm. Sự hiện diện ngày càng tăng của âm thanh lớn hoặc dai dẳng từ tàu, thiết bị sonar, giàn khoan dầu và thậm chí từ các nguồn tự nhiên như động đất có thể phá vỡ sự di cư, giao tiếp và mô hình sinh sản của nhiều động vật biển, đặc biệt là động vật có vú sống dưới nước như cá voi và cá heo.

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 33 to 37.

Different cultures follow their own special customs when a child’s baby teeth fall out. In Korea, for example, they have the custom of throwing lost teeth up on the roof of a house. According to tradition, a magpie will come and take the tooth. Later, the magpie will return with a new tooth for the child. In other Asian countries, such as Japan and Vietnam, children follow a similar tradition of throwing their lost teeth onto the roofs of houses.

Birds aren't the only animals thought to take lost teeth. In Mexico and Spain, tradition says a mouse takes a lost tooth and leaves some money. However, in Mongolia, dogs are responsible for taking teeth away. Dogs are highly respected in Mongolian culture and are considered guardian angels of the people.

Tradition says that the new tooth will grow good and strong if the baby tooth is fed to a guardian angel. Accordingly, parents in Mongolia will put their child's lost tooth in a piece of meat and feed it to a dog.

The idea of giving lost teeth to an angel or fairy is also a tradition in the West. Many children in Western countries count on the Tooth Fairy to leave money or presents in exchange for a tooth. The exact origins of the Tooth Fairy are a mystery, although the story probably began in England or Ireland centuries ago. According to tradition, a child puts a lost tooth under his or her pillow before going to bed. In the wee hours, while the child is sleeping, the Tooth Fairy takes the tooth and leaves something else under the pillow. In France, the Tooth Fairy leaves a small gift. In the United States, however, the Tooth Fairy usually leaves money. These days, the rate is $ 1 to $5 per tooth, adding up to a lot of money from the Tooth Fairy!
