(19)__________________carbon dioxide contributes to 'greenhouse gases', our carbon footprints have a direct impact (20)________________the environment. You can estimate your carbon footprint on any number of popular websites: if it's small, then you're probably leading a relatively green lifestyle. But what happens if it's big?

Choose A, B, C or D to indicate the underlined part that needs correction in each of the following questions.

Right now, a private company is developing something called ET3. ET3 stands for Evacuated Tube Transport Technology.

The ET3 system would reportedly be able to take passengers from New York to Beijing in just two hours. Here is how it works. A vacuum tube goes all the way from New York to Beijing. The tube is only a few meters wide. Capsules move through the tube. Six people can sit in one capsule. The capsules use electricity instead of gasoline. For international travel, the capsules can travel at about 6,500 kilometers per hour. That is much faster than an airplane!

So how can these capsules travel so fast? The answer is that there is no air inside the tube. When airplanes fly, they have to move through the air. The air resistance slows the airplanes down. Because there is no air in the ET3 tubes, the capsules are able to move at a very high speed. Besides, the capsules are quite light. They only weigh 183 kilograms.

Of course, ET3 doesn’t exist yet. Developers still have to solve a lot of problems. The biggest problem is that right now, ET3 would be far too expensive. In order to make ET3 cheaper, we will need much better technology. Maybe someday, you will be able to have lunch in New York and dinner in Beijing.

23. The word “works” in paragraph 2 is closest in meaning to ______.

a. travels b. operates c. earns money d. succeeds

24. According to the passage, which statement is NOT true.

a. Each ET3 capsule can carry up to six people.

b. We don’t know how to build its capsules

c. Speed in ET3 system is 6,500 km/h for international travel.

d. ET3 can travel a little faster than an airplane.

25. What can be inferred from the passage?

a. There is still a lot to do before putting ET3 into operation.

b. In the future, people will mainly use ET3 to travel abroad.

c. ET3 won’t be used domestically due to its high-cost

d. ET3 will soon be cheaper.

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.
