A rather surprising geographical feature of Antarctica is that a huge freshwater, one of the world's largest and deepest, lies hidden there under four kilometers of ice. Now known as Lake Vostok, this huge body of water is located under the ice block that comprises Antarctica. The lake is able to exist in its unfrozen state beneath this block of ice because its waters are warned by geothermal heat from the earth's core. This thick glacier above Lake Vostok actually insulates it from frigid temperatures (the lowest ever recorded on Earth) on the surface.

The lake was first discovered in the 1970s while a research team was conducting an aerial survey of the area. Radio waves from the survey equipment penetrated the ice and revealed a body of water of indeterminate size. It was not until much more recently that data collected by satellite made scientists aware of the tremendous size of the lake; satellite-borne radar detected an extremely flat region where the ice remains level because it is floating on the water of the lake.

The discovery of such a huge fresh water lake trapped under Antarctica is of interest to the scientific community because of the potential that the lake contains ancient microbes that have survived for thousands upon thousands of years, unaffected by factors such as nuclear fallout and elevated ultraviolet light that have affected organisms in more exposed areas. The downside of the discovery, however, lies in the difficulty of conducting research on the lake in such a harsh climate and in the problems associated with obtaining uncontaminated samples from the lake without actually exposing the lake to contamination. Scientists are looking for possible ways to accomplish this.

All of the following are true about the 1970 survey of Antarctica EXCEPT that it ______.

A. was conducted by air

B. made use of radio waves

C. did not measure the exact size of the lake

A. những phát hiện khác trên bề mặt Nam cực

B. vấn đề với các thiết bị truyền radar qua vệ tinh

C. các cách để nghiên cứu hồ Vostok mà không làm hư hại đến nó

D. thời tiết khắc nghiệt ở Nam Cực

Giải thích: Ở đoạn 3 đã nói về việc các nhà khoa học đang tìm cách để nghiên cứu mà không gây tổn hại cho hồ, như vậy đoạn 4 có khả năng tiếp tục bản về vấn đề này. Nếu bàn về A, B, D thì không sai nhưng không tạo được mạch liên kết giữa các đoạn và còn hơi lệch vấn đề: đặc điểm địa lý khác lạ ở Nam Cực.

Bài dịch

Một đặc điểm địa lý đáng ngạc nhiên của Nam Cực đó là một vùng nước ngọt khổng lồ, một trong những vùng lớn nhất và sâu nhất trái đất, nằm ẩn dưới bốn km băng. Bây giờ được gọi là hồ Vostok, lượng nước khổng lồ này nằm dưới khối băng tạo nên Nam Cực. Hồ có thể tồn tại ở trạng thái lỏng dưới khối băng là do nước được làm ấm bởi địa nhiệt từ lõi trái đất. Sông băng dày trên hồ Vostok bảo vệ nó khỏi nhiệt độ băng giá trên bề mặt (thấp nhất từng được ghi lại trên Trái đất).

Hồ lần đầu tiên được phát hiện vào những năm 1970 khi một nhóm nghiên cứu đã tiến hành một cuộc khảo sát trên không của khu vực. Sóng vô tuyến từ các thiết bị khảo sát thâm nhập vào băng và phát hiện một vùng nước có kích thước bất định. Đến gần đây các dữ liệu thu thập bởi vệ tinh mới cho các nhà khoa học biết được được kích thước to lớn của hồ; vệ tinh truyền qua radar phát hiện một khu vực cực kỳ bằng phẳng, nơi các băng đá đang còn nguyên vì nó trôi nổi trên mặt nước của hồ.

Việc phát hiện ra một hồ nước ngọt lớn ở dưới Nam Cực là điều mà cộng đồng khoa học rất quan tâm vì có khả năng hồ còn chứa vi sinh vật cổ đại sống sót trong hàng ngàn hàng ngàn năm, không bị ảnh hưởng bởi các yếu tố như bụi phóng xạ hạt nhân và ánh sáng tia cực tím cao đã ảnh hưởng đến những vùng có ánh mặt trời bức xạ rộng. Mặt tiêu cực của các phát hiện này nằm ở việc khó khăn khi phải tiến hành nghiên cứu trên hồ trong điều kiện khí hậu khắc nghiệt và các vấn đề liên quan đến việc thu thập các mẫu không bị ô nhiễm lấy từ hồ mà không thực sự gây hư hại gì đến hồ. Các nhà khoa học đang tìm cách để có thể thực hiện điều này.

Read the following passage and mark the letter A, B, C, or D to indicate the correct answer to each of the question.

Alaska is disappearing slowly, but surely. It is estimated that since the 19505, as much as fifteen percent of Alaska's land area has disappeared. How can a whole state be disappearing? The problem is that Alaska’s glaciers are melting. The state has more than 100,000 glaciers. These glaciers account for about 75,000 square kilometers, or five percent, of the state’s area. That is an area of land larger than Ireland!

According to a recent report by the US Geological Survey, ninety-nine percent of Alaska's glaciers are either retreating or diminishing. This diminishing seems mainly due to the increase in global temperatures. Since the 19605, the average year-round temperature has increased by almost 3°C. Additionally, the average winter temperature has increased by over 6°C. Presently, an estimated 100 cubic kilometers of ice is disappearing from Alaskan glaciers every year. It may be even more in the near future, as some scientists predict that the average world temperature could go up 4 to 7°C by the year 2100.

Another problem facing Alaska is its thawing permafrost. Much of the land in Alaska used to be permanently frozen or frozen for most of the year. Now, the thawing permafrost is causing a number of problems for people living in Alaska. Roads and utility poles are collapsing as the ground around and under them warms and soften. Also, the hard permafrost that originally prevented beaches from eroding during violent storms is now melting. People who live along Alaska's coasts are being forced to relocate. For villages on small low islands, one terrible storm could wipe out the entire community.

The melting permafrost and increasing temperatures are both affecting the forests of Alaska. As the permafrost under the forests melts, insects that normally do not turn up until the warmer seasons are appearing sooner. The spruce-bark beetle, for example, is increasing in numbers as a result of warmer winter temperatures. It usually takes about two years for these beetles to grow and reproduce in. very cold weather. However, due to the increase in temperatures, spruce-bark beetles are reproducing faster and damaging as many trees in one year as they previously damaged in two. If something cannot be done to

change things, Alaska's forests will not survive the turn of the century.

Some scientists believe that human activity is linked to a global increase in weather temperature. Whatever the cause of rising temperatures may be, the fact remains that temperatures are warming, affecting Alaska for the worse. Horribly, this could be a preview of what will happen to the rest of the world in the next century.

What is predicted in the last paragraph?

A. Human activities are likely to increase the weather temperature.

B. The Earth is getting worse due to the inﬂuences of global warming.

C. There will be other reasons why the temperature is rising.

D. Alaska's forests will disappear in the next century.

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.

For a time, the Hubble telescope was the brunt of jokes and subject to the wrath of those who believed the U.S. government had spent too much money on space projects that served no valid purpose. The Hubble was sent into orbit with a satellite by the Space Shuttle Discovery in 1990 amid huge hype and expectation. Yet after it was in position, it simply did not work, because the primary mirror was misshapen. It was not until 1993 that the crew of the Shuttle Endeavor arrived like roadside mechanics, opened the hatch that was installed for the purpose, and replaced the defective mirror with a good one.

Suddenly, all that had originally been expected came true. The Hubble telescope was indeed the “window on the universe,” as it had originally been dubbed. When you look deep into space, you are actually looking back through time, because even though light travels at 186,000 miles a second, it requires time to get from one place to another. In fact, it is said that in some cases, the Hubble telescope is looking back eleven billion years to see galaxies already forming. The distant galaxies are speeding away from Earth, some traveling at the speed of light.

Hubble has viewed exploding stars such as the Eta Carinae, which clearly displayed clouds of gas and dust billowing outward from its poles at 1.5 million miles an hour. Prior to Hubble, it was visible from traditional telescopes on earth, but its details were not ascertainable. But now, the evidence of the explosion is obvious. The star still burns five million times brighter than the sun and illuminates clouds from the inside.

Hubble has also provided a close look at black holes, which are described as cosmic drains. Gas and dust swirl around the drain and are slowly sucked in by the incredible gravity. It has also looked into an area that looked empty to the naked eye and, within a region the size of a grain of sand, located layer upon layer of galaxies, with each galaxy consisting of billions of stars.

The Hubble telescope was named after Edwin Hubble, a 1920s astronomer who developed a formula that expresses the proportional relationship of distances between clusters of galaxies and the speeds at which they travel. Astronomers use stars known as Cepheid variables to measure distances in space. These stars dim and brighten from time to time, and they are photographed over time and charted. All the discoveries made by Hubble have allowed astronomers to learn more about the formation of early galaxies.
