The Atmosphere of Venus

          Venus, also called the Morning Star and Evening Star, is the second-closest planet to the sun and the brightest object in the night sky. The planet orbits the sun every two hundred and twenty four Earth-days and is sometimes referred to as Earth’s sister planet because the two share both a similar size and bulk. What is not similar, however, is Venus’s atmosphere in comparison to Earth’s atmosphere.

          The atmosphere on Venus is much heavier and has a higher density than that of Earth. Venus’s atmosphere also expands significantly higher than Earth’s atmosphere although a thick cloud cover makes the surface of Venus nearly impossible to see unless observed through radar mapping.

          While the pressure and temperature of Venus’s upper atmosphere are comparable to those of Earth, the heat and pressure of the lower atmosphere are not unlike a furnace. Venus’s atmosphere is very thick due to a composition consisting mainly of carbon dioxide, and a small amount of nitrogen. If man could survive the extreme heat of Venus’s surface (400 degrees Celsius), then he would have to contend with a surface pressure that is more than 90 times that of Earth. Venus’s extremely high temperature is thanks to the greenhouse effect caused by such a large amount of carbon dioxide. The greenhouse effect is a process by which the sun’s infrared radiation is more readily absorbed by the atmosphere. Just like in a real greenhouse used to grow plants years round, the proliferation of carbon dioxide traps radiation and warms Venus’s atmosphere. Due to this phenomenon, Venus boasts a higher atmospheric temperature than Mercury, even though Venus is twice the distance from the sun.

          However, scientists postulate that Venus’s atmosphere was not always so hot. Studies show that large bodies of water were once on Venus’s surface but that eventually evaporation of all the water caused the runaway greenhouse effect which regulates the planet today.Thus Venus has become a critical study for today’s scientists, as human being are only beginning to struggle with the early stages of the greenhouse effect. Our problems do not stem from evaporated water supplies but from a propagation of carbon dioxide and other greenhouse gases due to industrial and automobile emissions.

          Another interesting characteristic to note regarding Venus’s atmosphere is that its daytime temperatures and nighttime temperatures are not that far removed from each other. This is due to the thermal inertia, the ability of a substance to store heat despite changing temperatures and the transfer of heat by Venus’s strong winds. Although winds on the surface of Venus move slowly in comparison with Earth’s winds, Venus’s air is so dense that a slow-moving there can move large obstructions and even skip stones along the planet’s surface.

          In 1966, humankind made its first attempt at sending a recording instrument into Venus’s atmosphere. The Venera 3 probe did collide with Venus surface; however, the abrupt impact caused its communication system to fail, and it was unable to send and feedback. In 1967, Venera 4 successfully enter Venus’s atmosphere and was able to take many readings, one of which recorded that Venus’s atmosphere was between ninety and ninety-five percent carbon dioxide. Subsequent Venera probes were sent into Venus’s atmosphere, but most of them succumbed to the crushing air pressure.

According to paragraph 1, Venus is named the Morning Star and Evening Star because

A. it is very bright

B. it is close to the sun

C. it can be seen from evening till morning

D. it is used to find the direction by sailors

Đáp án A

Thông tin: Venus, also called the Morning Star and Evening Star, is the second-closest planet to the sun and the brightest object in the night sky.

Dịch nghĩa: Sao Kim, cũng được gọi là Sao Mai và Sao Hôm, là hành tinh thứ hai gần Mặt Trời và là vật thể sáng nhất trên bầu trời đêm.

Như vậy Sao Kim được gọi là Sao Mai và Sao Hôm là bởi vì nó là ngôi sao sáng nhất. Phương án A. it is very bright = nó rất sáng; là phương án chính xác nhất.

          B. it is close to the sun = nó gần với Mặt Trời.

Vì nó gần với Mặt Trời nên nó mới là ngồi sao sáng nhất nên mới được đặt tên như vậy. Tóm lại vẫn là do độ sáng của nó mà sao Kim được đặt thêm 2 cái tên khác nữa.

          C. it can be seen from evening till morning = nó có thể được nhìn thấy từ tối đến sáng.

Không có thông tin như vậy trong bài.

          D. it is used to find the direction by sailors = nó được sử dụng để tìm hướng bởi các thủy thủ.

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   22  to  26

A.   Read the passage carefully, then choose the correct answer.

The ruined temples of Angkor are perhaps one of the mast impressive Seven Wonders of the World. Located in modern day Cambodia near Lake TonIe Sap, the largest freshwater lake in Asia, Angkor was the seat of power for the Khmer Empire from the ninth to the fifteenth century. The ruins of Angkor are documented as same .of the mast 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 far the downfall of the Khmer Empire has to do with the inhabitants' irrigation system. The temple 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 rice patties and farmland during the course of the year. Farmers were completely dependent upon the water for their 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 systems 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 the 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 quicker and more efficiently. After centuries of continual use, the irrigation system was pushed beyond its capacity. Soil erosion, nutrient depletion, and the loss of water led to decrease in the food supply. With 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.

22. What is the passage mainly about?

A. Modern day agricultural procedures in Cambodia.

B. A possible explanation for the, decline of a civilization.

C. The essential role water plays in farming.

D. Religious temples of the ancient Khmer Empire.

23. The passage preceding the passage 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

24. According to the passage, Lake Tonle Sap in Cambodia ______.

A. is an enormous fresh body of water in Asia

B. was unable to supply enough fish for the people of Angkor

C. became polluted due to a population explosion

D. is one of the Seven Wonders of the World

25. Why does the author mention the hydraulic systems of the reservoirs?

A. They supplied irrigation from the Indian Ocean.

B. They became non-functional due to overuse.

C. They were destroyed by nearby warrior tribes.

D. They helped transport the sandstones for constructing temples.

26. It can be inferred from the passage that the inhabitants of the Khmer Empire ______.

A. were intentionally starved by the farmers

B. lost their food source due to excess rainfall

C. supplemented their diets with 'meat hunted in the nearby jungles

D. depended upon rice as their main source of food

27. All the following are mentioned as events that can affect food supply EXCEPT.

A. erosion of soil                                       B. contamination of soil

C. reduction of nutrients                            D. loss of water supply
