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 following questions from 1 to 5.

Dolphins are one of the most intelligent species on the planet, which makes them a very interesting animal to scientists. In their natural habitats, dolphins use various vocalization techniques. They whistle and squeak to recognize members of their pod, identify and protect their young, and call out warnings of danger. They also make clicking sounds used for echolocation to find food and obstacles in dark and murky waters.

Amazingly, the whistling sound that the bottlenose dolphin makes has been found to have a similar pattern to human language. They always make conversational sounds when they greet each other. If you listen to dolphins' squeaks and squeals, it will sound like they are having a conversation.

Dolphins usually use both sound and body language to communicate with each other. It is through gesture and body language, however, that most of their communication with humans comes. Dolphins can be trained to perform complicated tricks. This suggests they have a high level of intelligence and communication capacity. If they work for a long time with a trainer, they are able to recognize and understand human commands.

A lot of dolphin communication has been studied using dolphins in captive environments. These studies have been criticized because some marine biologists believe that dolphins living in aquariums or research centers cannot be considered "normal." Even so, most believe that studying dolphin communication in captivity is useful for beginning to understand the complexity of dolphin communication. After all, dolphins are one of the most intelligent animals. Their ability to communicate is impressive and worthy of study.

According to paragraph 4, what do some marine biologists think about captive dolphins?

A. Their relationships are too personal with marine biologists.

B. They can't be considered accurate subjects for biological studies.

C. They can communicate exactly the same as humans do.

D. They easily demonstrate how dolphins act in the wild.

Theo đoạn 4, một số nhà sinh học biển nghĩ gì về cá heo nuôi nhốt?

A. Mối quan hệ của chúng quá riêng tư với các nhà sinh học biển.

B. Chúng không thể được coi là đối tượng chính xác cho các nghiên cứu sinh học.

C. Chúng có thể giao tiếp giống hệt như con người.

D. Họ dễ dàng chứng minh cách cá heo hành động trong tự nhiên.

Thông tin: A lot of dolphin communication has been studied using dolphins in captive environments. These studies have been criticized because some marine biologists believe that dolphins living in aquariums or research centers cannot be considered "normal."

Tạm dịch: Rất nhiều hành vi giao tiếp của cá heo đã được nghiên cứu bằng cách để cá heo trong môi trường nuôi nhốt. Những nghiên cứu này đã bị chỉ trích vì một số nhà sinh học biển tin rằng cá heo sống trong bể cá hoặc trung tâm nghiên cứu không thể được coi là "bình thường".

Dịch bài đọc:

Cá heo là một trong những loài thông minh nhất hành tinh, điều đó khiến chúng trở thành một loài động vật rất thú vị đối với các nhà khoa học. Trong môi trường sống tự nhiên của chúng, cá heo sử dụng các kỹ thuật phát âm khác nhau. Chúng huýt sáo và ré lên để nhận ra các thành viên trong nhóm của mình, xác định và bảo vệ những con cá heo con, đồng thời kêu gọi cảnh báo nguy hiểm. Chúng cũng tạo ra âm thanh nhấp chuột được sử dụng cho tiếng vang để tìm thức ăn và chướng ngại vật trong vùng nước tối và âm u.

Thật đáng ngạc nhiên, âm thanh huýt sáo mà cá heo mũi chai tạo ra đã được tìm thấy có một đặc điểm tương tự như ngôn ngữ của con người. Chúng luôn tạo ra những âm thanh trò chuyện khi chào nhau. Nếu bạn lắng nghe tiếng ré và tiếng rít của cá heo, có vẻ như chúng đang có một cuộc trò chuyện.

Cá heo thường sử dụng cả âm thanh và ngôn ngữ cơ thể để giao tiếp với nhau. Nó giao tiếp thông qua cử chỉ và ngôn ngữ cơ thể, tuy nhiên, hầu hết điều đó được huấn luyện bởi con người. Cá heo có thể được huấn luyện để thực hiện các thủ thuật phức tạp. Điều này cho thấy chúng có trí thông minh và năng lực giao tiếp cao. Nếu chúng được huấn luyện trong một khoảng thời gian dài với một huấn luyện viên, chúng có thể nhận ra và hiểu các mệnh lệnh của con người.

Rất nhiều hành vi giao tiếp của cá heo đã được nghiên cứu bằng cách để cá heo trong môi trường nuôi nhốt. Những nghiên cứu này đã bị chỉ trích vì một số nhà sinh học biển tin rằng cá heo sống trong bể cá hoặc trung tâm nghiên cứu không thể được coi là "bình thường". Mặc dù vậy, hầu hết đều tin rằng nghiên cứu hành vi giao tiếp của cá heo trong điều kiện nuôi nhốt là hữu ích để bắt đầu hiểu được sự phức tạp trong sự giao tiếp cá heo. Xét cho cùng, cá heo là một trong những loài động vật thông minh nhất. Khả năng giao tiếp của chúng rất ấn tượng và đáng để nghiên cứu.

     Most Americans look forward to their vacations. Most American employees receive an annual vacation with pay. It is traditional to use this time off for travel.

Obtaining a passport is not difficult. Every year about thirteen million people travel abroad. The most popular periods are during the Summer and the two-week retool break on Christmas and New Year holidays. These periods are so the most crowded and the most expensive time to travel, so people who can adjust their schedules sometimes choose to travel in the autumn.

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. 

One of the most urgent environmental problems in the world today is the shortage of clean water. Having clean drinking water is a basic human right. However, acid rain, industrial pollution and garbage have made many sources of water undrinkable. 

Lakes, reservoirs and even entire seas have become vast pools of poison. Lake Baikal in Russia is one of the largest lakes in the world. It contains a rich variety of animals and plants, including 1,300 rare species that do not exist anywhere else in the world. Yet, they are being destroyed by the massive volumes of industrial effluent which pour into the lake every day. Even though laws have been made, the governments do not have the power to enforce them. Most industries simply ignore the regulations. The Mediterranean Sea occupies 1% of the world's water surface, but it is the dumping ground for 50% of all marine pollution. Almost sixteen countries regularly throw industrial wastes a few miles offshore. 

Water is free to everyone. A few years ago people thought that the supply of clean water in the world was limitless. Today, many water supplies have been ruined by pollution and sewage. Clean water is now scarce, and we are at last beginning to respect it. What should we do to save this precious source?

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
