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 concept of obtaining fresh water from iceberg that is towed to populated areas and arid regions of the world was once treated as a joke more appropriate to cartoons than real life. But now it is being considered quite seriously by many nations, especially since scientists have warned that the human race will outgrow its fresh water supply faster than it runs out of food. Glaciers are a possible source of fresh water that has been overlooked until recently. (A)
Three-quarters of the Earth's fresh water supply is still tied up in glacial ice, a reservoir of untapped fresh water so immense that it could sustain all the rivers of the world for 1,000 years. Floating on the oceans every year are 7,659 trillion metric tons of ice encased in 10,000 icebergs that break away from the polar ice caps, more than ninety percent of them from Antarctica. (B)
Huge glaciers that stretch over the shallow continental shelf give birth to icebergs throughout the year. Icebergs are not like sea ice, which is formed when the sea itself freezes; rather, they are formed entirely on land, breaking off when glaciers spread over the sea. As they drift away from the polar region, icebergs sometimes move mysteriously in a direction opposite to the wind, pulled by subsurface currents. Because they melt more slowly than smaller pieces of ice, icebergs have been known to drift as far north as 35 degrees south of the equator in the Atlantic Ocean. (C)
The difficulty arises in other technical matters, such as the prevention of rapid melting in warmer climates and the funneling of fresh water to shore in great volume. But even if the icebergs lost half of their volume in towing, the water they could provide would be far cheaper than that produced by desalination, or removing salt from water. (D)
Trả lời cho các câu 125852, 125853, 125854, 125855, 125856, 125857, 125858, 125859, 125860, 125861 dưới đây:
Đáp án đúng là: B
Đoạn văn nói về icebergs như một nguồn nước sạch, trong đoạn 1 có “obtaining fresh water from iceberg…”, đoạn 2 có “Three-quarters of the Earth's fresh water supply…”, đoạn cuối có “the water they could provide….”
Cách tạo ra icebergs, hướng trôi của icebergs,… cũng được nhắc đến trong bài
Đáp án đúng là: A
“arid” =” anhydrous”: khô cằn, khô khan (đất, khí hậu)
Đáp án đúng là: B
“it” được thay thế cho “obtaining fresh water from iceberg” trong câu: “The concept of obtaining fresh water from iceberg that is towed to populated areas and arid regions of the world was once treated as a joke more appropriate to cartoons than real life.”
Đáp án đúng là: C
Thông tin ở câu cuối đoạn 1: “Glaciers are a possible source of fresh water that has been overlooked until recently.”
Đáp án đúng là: D
“currents” = “flows of water”: dòng, luồng chảy của nước
Đáp án đúng là: A
Thông tin ở đoạn 3: “Icebergs are not like sea ice, which is formed when the sea itself freezes; rather, they are formed entirely on land, breaking off when glaciers spread over the sea.”
Đáp án đúng là: A
Thông tin: “As they drift away from the polar region, icebergs sometimes move mysteriously in a direction opposite to the wind, pulled by subsurface currents.” Vì thế, icebergs hoàn toàn có thể trôi đến những vùng khô cằn hơn
Đáp án đúng là: C
Phía trước đề cập đến thực tế về sự trôi nổi của icebergs: “Because they melt more slowly than smaller pieces of ice, icebergs have been known to drift as far north as 35 degrees south of the equator in the Atlantic Ocean.” Vì thế Câu in đậm phù hợp nhất khi được nối tiếp ở đây
Đáp án đúng là: B
“that” được thay thế cho “the water” trong câu “the water they could provide would be far cheaper ..”
Đáp án đúng là: D
Thông tin ở câu đầu tiên đoạn cuối: “The difficulty arises in other technical matters, such as the prevention of rapid melting in warmer climates and the funneling of fresh water to shore in great volume.”
