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 38 to 45.

Oxford University scientists have launched an attempt to bring the Northern White Rhinoceros back from beyond the “point of no return” using IVF (In Vitro Fertilization). The team believes a pioneering treatment can prompt a revival of the persecuted species, despite the death last year of the last known male and the fact that the two remaining females, Najin and Fatu, cannot have calves.

One of two subspecies of White Rhinoceros, the Northern Rhinoceros once ranged over tracts of Uganda, Sudan, Central African Republic and the Democratic Republic of Congo. However, the value of its horns saw it poached from a population of approximately 500 to 15 in the 1970s and 1980s. A small recovery – numbers reached 32 – from the early 1990s was then reversed from 2003 when illegal hunting intensified again.

The Oxford researchers believe that it will be possible to remove ovarian tissue from the animals and stimulate it to produce eggs, which would then be fertilized from sperm preserved from male Northern White Rhinoceros. The embryos would then be implanted into a surrogate mother of a similar species, probably a Southern White Rhinoceros. The technique has been used successfully in mice for nearly two decades; it has also been accomplished for some species of dog, horse and cat. However, it has never been attempted before on a rhinoceros, meaning the Oxford team plan to perfect it first by conducting a series of trials on ovarian tissue taken from a Southern White Rhinoceros.

In principal, the benefit of removing ovarian tissue for use in the lab is that it can go on producing eggs. Other researchers are exploring the possibility of using the remaining Northern White Rhinoceros sperm to cross–breed with Southern White Rhinoceros, however Dr Williams believes the focus should be on preserving the identity of the northern species. “This will be a huge buffer against disease and ill health in the long–term, and give the new herds better genetic ability to adapt to changing environments in the future.”

Najin was born in captivity in 1989 and Fatu in 2000. They both belong to the Cvur Kralove Zoo in the Czech Republic, which shipped them to the Ol Pejeta Conservancy in Kenya in 2009 amid tight security. In place of their horns, keepers have fitted radio transmitters to allow close monitoring of their whereabouts in the large paddock areas. The team has enough funding for three years’ research, donated from Foundation Hoffman, however Oxford University has launched a public appeal to raise the money to secure the project long term.

Which of the following best serves as the title for the passage?

A. Oxford University in an Attempt to Protect an Endangered Species.

B. Oxford University to Launching a Campaign to Raise Public Awareness of Rhinoceros.

C. Oxford University Pondering Changes to Fertilizing Techniques.

D. Oxford University Holding a Public Appeal to Raise the Animal Protection Fund.

Dịch bài đọc:

Các nhà khoa học của Đại học Oxford đã đưa ra một nỗ lực để đưa Tê giác trắng phương Bắc trở lại từ bên ngoài điểm không thể quay trở lại bằng cách sử dụng IVF (thụ tinh trong ống nghiệm). Nhóm nghiên cứu tin rằng một phương pháp điều trị tiên phong có thể thúc đẩy sự hồi sinh của các loài bị đàn áp, mặc dù cái chết năm ngoái của con đực được biết đến cuối cùng và thực tế là hai con cái còn lại, Najin và Fatu, không thể có bắp chân.

Một trong hai phân loài của Tê giác trắng, Tê giác phương Bắc đã từng trải dài trên các vùng của Uganda, Sudan, Cộng hòa Trung Phi và Cộng hòa Dân chủ Congo. Tuy nhiên, giá trị của sừng của nó đã thấy nó bị săn trộm từ dân số khoảng 500 đến 15 trong những năm 1970 và 1980. Một sự phục hồi nhỏ – con số đạt 32 – từ đầu những năm 1990 sau đó đã bị đảo ngược từ năm 2003 khi nạn săn bắn bất hợp pháp tăng cường trở lại.

Các nhà nghiên cứu Oxford tin rằng sẽ có thể loại bỏ mô buồng trứng khỏi động vật và kích thích nó sản xuất trứng, sau đó sẽ được thụ tinh từ tinh trùng được bảo quản từ tê giác trắng phương Bắc. Các phôi thai sau đó sẽ được cấy vào một người mẹ thay thế của một loài tương tự, có thể là một con tê giác trắng phương Nam. Kỹ thuật này đã được sử dụng thành công trên chuột trong gần hai thập kỷ; nó cũng đã được thực hiện cho một số loài chó, ngựa và mèo. Tuy nhiên, nó chưa bao giờ được thử trước đây trên một con tê giác, có nghĩa là nhóm Oxford có kế hoạch hoàn thiện nó trước bằng cách thực hiện một loạt các thử nghiệm trên mô buồng trứng lấy từ một con tê giác trắng phương Nam.

Về nguyên tắc, lợi ích của việc loại bỏ mô buồng trứng để sử dụng trong phòng thí nghiệm là nó có thể tiếp tục sản xuất trứng. Các nhà nghiên cứu khác đang khám phá khả năng sử dụng tinh trùng tê giác trắng phương Bắc còn lại để lai tạo với tê giác trắng phương Nam, tuy nhiên, tiến sĩ Williams tin rằng cần tập trung vào việc giữ gìn bản sắc của các loài phía bắc. Về lâu dài, đây sẽ là một bước đệm lớn chống lại bệnh tật và sức khỏe kém, và mang lại cho đàn gia súc mới khả năng di truyền tốt hơn để thích nghi với môi trường thay đổi trong tương lai.

Najin được sinh ra trong điều kiện nuôi nhốt vào năm 1989 và Fatu vào năm 2000. Cả hai đều thuộc sở thú Cvur Kralove ở Cộng hòa Séc, nơi đã chuyển chúng đến Bảo tồn Ol Pejeta ở Kenya vào năm 2009 trong bối cảnh an ninh chặt chẽ. Thay cho sừng của chúng, những người canh gác đã lắp thiết bị phát sóng vô tuyến để cho phép theo dõi chặt chẽ nơi ở của chúng trong khu vực bãi lớn. Nhóm nghiên cứu có đủ tài chính cho ba năm nghiên cứu, được tài trợ từ Fondation Hoffman, tuy nhiên Đại học Oxford đã đưa ra một lời kêu gọi công khai để quyên tiền để bảo đảm dự án lâu dài.

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.

There is one planet that still fascinates and teases scientists mainly because it doesn’t have an atmosphere to obscure observation, yet it is not big enough for sufficiently accurate telescopic observation. The fact that it is also very close to the sun also makes it difficult for astronomers.

However, space telescopes have told us a lot more about Mercury. It is rather similar to Earth’s moon and to Mars. There are mountainous areas dotted with craters and large valleys which are uncratered. The moon’s valleys have fewer cracks and ridges are smoother. Mercury’s valleys are filled with volcanic rocks, similar to on the moon, yet there is no evidence of volcanoes, even extinct ones, on Mercury, as there is on the both Mars and the moon, and of course here on Earth.

So, scientists presume the valleys on Mercury were caused by different things, that is to say not by volcanoes, but by very large meteorites, which also caused the cracks in the terrain and left the ridges rough and uneven. More and better photos of Mercury are at present at best only hypotheses.

Question28. What is the main topic of this passage?

A. Astronomers’ difficulties. C. The Earth’s moon.

B. Observation of planets. D. The planet, Mercury

Question29. Why does Mercury still tease scientists?

A. Because it has an atmosphere which obscures observation.

B. Because it is too close to the sun.

C. Because it is difficult for space probes to get close to.

D. Because it is too small.

Question30. What is true about Mercury but not true about the moon or Mars?

A. The valleys are filled with volcanic rocks. C. There are no volcanoes.

B. The valleys are uncratered. D. They are hilly regions.

Question31. What does the author imply space telescopes can do better than land-based telescopes?

A. Show more of the planet, Mercury. C. Show what caused Mercury’s valleys.

B. Show the meteorites which hit Mercury. D. Show the volcanoes on Mercury. 

Question32. What can we infer from the passage that astronomers still need to get more detailed observation of Mercury?

A. More hypotheses C. Larger space telescopes.

B. Better and more space telescopes. D. More ways to prove hypotheses.

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

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.

     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.

    Travelling within the United States is very popular because foreign travel generally takes more time and money. However, those who want to travel outside the USA are free to go almost everywhere. 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.

    American tourists often travel by car. Most families own a car, and those who do not have a car can rent one. Cars are usually the most economical way to travel, especially for families. It is also fairly fast and convenient. Excellent highways with motels and restaurants nearby connect the nation's major cities. They enable tourists to travel at a speed of 55 to 66 miles an hour. Tourists that want to travel faster often fly to their destination and then rent a car when they get there.

Câu 1: According to the writer, most American employees traditionally use their annual vacations for

     A. jogging                       B. shopping                    C. travelling                  D. cycling
