On March 11, 2011, Japan suffered one of the greatest disasters in its history. The earthquakes and tsunami directly affected the Fukushima Nuclear Power Plant and a large amount of radioactive material was released into the atmosphere. The effects of this nuclear disaster continue that there has been none of human’s appearances since then, but wild animals survive in abandoned areas and the green cover is increasing. 

Immediately after the radioactive leak, the Japanese authorities evacuated all the residents away from the area immediately. However, the fact that the region was evacuated for humans does not mean the same for animals. Scientists working at the University of Georgia in the United States, have installed camera systems in almost every region of the nuclear disaster and wanted to determine what happened in the region. They gathering various images in a total of 120 days. Images of more than 46 thousand wild boars were captured. More than 26,000 of them were shot in a completely uninhabited area, while about 13,000 images were obtained from areas close to living spaces.

Scientists now want to carry out studies to understand the genetic condition of the animals in the area. However, the return of animals and plants in Fukushima has proved that without human’s interference, nature has its own way to keep a place for every animal and plants.

1. What can be the best title for the passage?

A. Nature takes over abandoned Fukushima areas.      

B. Fukushima nuclear disaster.

C. Scientists have been struggling with Japan's nuclear waste.

D. Natural disasters in Japan.

2.  What does the word "them" which is in bold in paragraph 2 refers to?

A. Scientists.             B. Images.                C. Days.                 D. Wild boars.

Vào ngày 11 tháng 3 năm 2011, Nhật Bản đã phải hứng chịu một trong những thảm họa lớn nhất trong lịch sử của mình. Động đất và sóng thần đã ảnh hưởng trực tiếp đến Nhà máy điện hạt nhân Fukushima và một lượng lớn chất phóng xạ đã được phát tán vào khí quyển. Ảnh hưởng của thảm họa hạt nhân này vẫn tiếp tục xảy ra, kể từ đó không có sự xuất hiện của con người, nhưng động vật hoang dã vẫn tồn tại trong những khu vực bị bỏ hoang và độ phủ xanh ngày càng tăng.

Ngay sau sự cố rò rỉ phóng xạ, nhà chức trách Nhật Bản đã sơ tán toàn bộ cư dân ra khỏi khu vực ngay lập tức. Tuy nhiên, thực tế là khu vực được sơ tán đối với con người không có nghĩa là đối với động vật. Các nhà khoa học làm việc tại Đại học Georgia, Hoa Kỳ, đã lắp đặt hệ thống camera ở hầu hết các khu vực xảy ra thảm họa hạt nhân và muốn xác định điều gì đã xảy ra trong khu vực. Họ thu thập nhiều hình ảnh khác nhau trong tổng số 120 ngày. Hình ảnh hơn 46 nghìn con lợn rừng bị bắt. Hơn 26.000 bức ảnh trong số đó được quay ở một khu vực hoàn toàn không có người ở, trong khi khoảng 13.000 bức ảnh được thu thập từ những khu vực gần với không gian sống.

Các nhà khoa học hiện muốn thực hiện các nghiên cứu để tìm hiểu tình trạng di truyền của các loài động vật trong khu vực. Tuy nhiên, sự trở lại của động vật và thực vật ở Fukushima đã chứng minh rằng không có sự can thiệp của con người, thiên nhiên có cách riêng để giữ chỗ cho mọi loài động vật và thực vật.

1. Cái gì có thể là tiêu đề tốt nhất cho đoạn văn?

A. Thiên nhiên tiếp quản các khu vực bị bỏ hoang ở Fukushima.

B. Thảm họa hạt nhân Fukushima.

C. Các nhà khoa học đã phải vật lộn với chất thải hạt nhân của Nhật Bản.

D. Thiên tai ở Nhật Bản.

2. Từ "họ" in đậm trong đoạn 2 dùng để chỉ điều gì?

A. Các nhà khoa học. B. Hình ảnh. C. Ngày. D. Lợn rừng.

3. Tại sao các nhà khoa học lại lắp đặt hệ thống camera trong vùng xảy ra thảm họa hạt nhân?

A. Vì họ muốn hiểu tình trạng di truyền của các loài động vật trong vùng.

B. Vì họ muốn đếm số lượng lợn rừng.

C. Vì họ muốn di tản toàn bộ cư dân ra khỏi vùng.

D. Vì họ muốn xem những gì đã xảy ra trong khu vực.

4. Có bao nhiêu hình ảnh về lợn rừng ở khu vực không có người ở?

A. 46.000 B. 13.000 C. 120.000 D. 26.000

5. Từ nào sau đây có thể thay thế từ "xác định" trong đoạn 2?

Earth is losing wildlife at a faster rate than at any time in history. This is according to the new "Living Planet Report" from the World Wildlife Fund. The report says the global wildlife population shrank by 60 per cent between 1970 and 2014. The WWF warned that: "Earth is losing biodiversity at a rate seen only during mass extinctions." Researchers state that most of the decline in our animal population is because of "exploding human consumption". There are more and more humans on this planet. We are eating more, overfishing, cutting down trees for beef production, consuming more, and using more energy and natural resources. This has resulted in a massive loss of habitat for animals.The report estimates that only a quarter of the world's land has been untouched by humans. This means human activity has greatly affected animals on three-quarters of Earth's surface. Researchers tracked more than 4,000 species of mammals, birds, reptiles, fish and amphibians. They say the loss of animal life is worst in South and Central America. These regions saw an 89 per cent loss in the population of vertebrates in the past four decades. The WWF wrote: "The astonishing decline in wildlife population...is a [depressing] reminder, and perhaps the ultimate indicator, of the pressure we [put] on the planet." It warned: "We can be the generation that had its chance and failed to act; that let Earth slip away."

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.

Earth is richly supplied with different types of living organisms which co-exist in their environments, forming complex, interrelated communities. Living organisms depend on one another for nutrients, shelter, and other benefits. The extinction of one species can set off a chain reaction that affects many other species, particularly if the loss occurs near the bottom of the food chain. For example, the extinction of a particular insect or plant might seem inconsequential. However, there may be fish or small animals that depend on that resource for foodstuffs. The loss can threaten the survival of these creatures and larger predators that prey upon them. Extinction can have a ripple effect that spreads throughout nature.

In addition to its biological consequences, extinction poses a moral dilemma for humans, the only species capable of saving the others. The presence of humans on the planet has affected all other life forms, particularly plants and animals. Human lifestyles have proven to be incompatible with the survival of some other species. Purposeful efforts have been made to eliminate animals that prey on people, livestock, crops, or pose any threat to human livelihoods. Some wild animals have been decimated by human desire for meat, hides, fur, or other body parts with commercial value. Likewise, demand for land, water, and other natural resources has left many wild plants and animals with little to no suitable habitat. Humans have also affected nature by introducing non-native species to local areas and producing pollutants having a negative impact on the environment. The combination of these human-related effects and natural obstacles such as disease or low birthrates has proven to be too much for some species to overcome. They have no chance of survival without human help.

As a result, societies have difficult choices to make about the amount of effort and money they are willing to spend to save imperiled species. Will people accept limits on their property rights, recreational activities, and means of livelihood to save a plant or an animal? Should saving such popular species as whales and dolphins take priority over saving obscure, annoying, or fearful species? Is it the responsibility of humans to save every kind of life form from disappearing, or is extinction an inevitable part of nature, in which the strong survive and the weak perish? These are some difficult questions that people face as they ponder the fate of other species living on this planet.

What does the passage mainly discuss?

A. Humans and endangered species

B. The importance of living organisms

C. Measures to protect endangered species

D. Causes of animal extinction

We live in a dynamic world, and habitats are always undergoing changes at all sorts of levels. However, natural changes usually occur at a slow pace so that impacts on individual species tend to be slight - at least in the short term
When the pace of change is greatly accelerated, there may be no time for individual species to react to new circumstances, and the effects can be disastrous. Briefly, this is the reason that rapid habitat loss is regarded as the chief cause of species endangerment, and there is no force more powerful in this regard than human beings. To some extent, every part of the earth has been affected by human activities, especially during this past century. This applies on virtually every scale, from the loss of microbes in soils that once supported tropical forests, to the extinction of fish and other aquatic species in polluted freshwater habitats, to changes in global climate caused by the release of greenhouse gases. From the perspective of an individual human lifetime, such changes may be hard to detect and their effects on individual species may be hard to predict. But the lesson is clear enough. For example, although many countries have had plans to grow many tropical forests, they are highly susceptible to destruction because the soils in which they grow are poor in available nutrients. Centuries may be required to bring back a forest that was cut down or burnt out in the space of a few years. Many of the world's severely threatened animals and plants live in such forests, and it is certain that huge numbers of them will disappear if present rates of forest loss continue. Habitats in the world are unchangeable and fixedly exist.

Chúng ta sống trong một thế giới năng động, và môi trường sống luôn luôn trải qua những thay đổi ở tất cả các cấp độ. Tuy nhiên, những thay đổi tự nhiên thường xảy ra ở tốc độ chậm để tác động đến từng loài có xu hướng nhỏ - ít nhất là trong ngắn hạn
Khi tốc độ thay đổi được tăng tốc đáng kể, có thể không có thời gian để các loài cá thể phản ứng với hoàn cảnh mới, và các hiệu ứng có thể là thảm họa. Tóm lại, đây là lý do khiến mất môi trường sống nhanh chóng được coi là nguyên nhân chính gây nguy hiểm cho loài, và không có lực lượng nào mạnh hơn trong vấn đề này so với con người. Ở một mức độ nào đó, mọi phần của trái đất đã bị ảnh hưởng bởi các hoạt động của con người, đặc biệt là trong thế kỷ qua. Điều này áp dụng trên hầu hết mọi quy mô, từ việc mất vi khuẩn trong đất đã từng hỗ trợ rừng nhiệt đới, đến sự tuyệt chủng của cá và các loài thủy sinh khác trong môi trường nước ngọt bị ô nhiễm, thay đổi khí hậu toàn cầu gây ra bởi việc thải khí nhà kính. Từ quan điểm của một đời người, những thay đổi như vậy có thể khó phát hiện và ảnh hưởng của chúng đối với từng loài có thể khó dự đoán. Nhưng bài học là đủ rõ ràng. Ví dụ, mặc dù nhiều quốc gia đã có kế hoạch trồng nhiều khu rừng nhiệt đới, chúng rất dễ bị phá hủy bởi vì các loại đất mà chúng phát triển rất nghèo trong các chất dinh dưỡng sẵn có. Nhiều thế kỷ có thể được yêu cầu mang lại một khu rừng bị cắt giảm hoặc bị đốt cháy trong không gian vài năm. Nhiều loài động vật và thực vật bị đe dọa nghiêm trọng trên thế giới sống trong các khu rừng như vậy, và chắc chắn rằng một số lượng lớn chúng sẽ biến mất nếu tỷ lệ mất rừng hiện tại tiếp tục. Môi trường sống trên thế giới là không thể thay đổi và tồn tại cố định.

One day in 1963, a dolphin named Elvar and a famous astronomer, Carl Sagan, were playing a little game. The astronomer was visiting an institute which was looking into the way dolphins communicate with each other. He was standing at the edge of one of tanks where several of these highly intelligent, friendly creatures were kept. Elvar had just swum up alongside him and had turned on his back. He wanted Sagan to scratch his stomach again, as the astronomer had done twice before. But this time Elvar was too deep in the water for Sagan to reach him. Elvar looked up at Sagan, waiting. Then, after a minute or so, the dolphin leapt up through the water into the air and made a sound just like the words "More!"

The astonished astronomer went to the director of the institute and told him about the incident.

"Oh, yes. That´s one of the words he knows," the director said, showing no surprise at all.

Dolphins have bigger brains in proportion to their body size than humans have, and it has been known for a long time that they can make a number of sounds. What is more, these sounds seem to have different functions, such as warning each other of danger. Sound travels much faster and further in water than it does in air. That is why the parts of the brain that deal with sound are much better developed in dolphins than in humans. But can it be said that dolphins have a "language", in the real sense of the word? Scientist don´t agree on this.

1/ The dolphin leapt into the air because

A. Sagan was too near the water

B. it was part of the game they were playing.

C. he wanted Sagan to scratch him again

D. Sagan wanted to communicate with him

2/ "Dolphins" brains are particularly well developed to

A. help them to travle fast in water

B. arrange sounds in different structures

C. respond to different kinds of sound

D. communicate with humans through sound

Read the text on the tight about the invention of semaphore. Five sentences have been removed. Choose from sentences A-F the one which fits each gap (l-4).There is one extra sentence which you do not need. There is an example at the beginning (0).

A Using ropes, these could be moved to form 49 different shapes that could be recognized easily.

B The main problem was that it could not be used during the night or on foggy days.

C These messages could be sent very quickly.

D The new republic faced enemies on all sides in the form of the forces of Britain, Austria, Holland, Prussia and Spain.

E In August 1794, it carried its first message, the news of Napoleon's victory at Le Quenoy.

F A system was built between London and the south coast, and other countries followed.

War has been called 'the mother of invention', and this was certainly true in the French Revolutionary wars in 1792. 1 | D | What the Revolutionary Government urgently needed was a reliable system of communication.

Claude Chappe, who was a priest and an engineer, had developed a telegraph system, but had not been able to test it fully. However, his brother Ignace was a member of the government, and arranged for Claude's system to be tested. It turned out to be a great success and started a new form of high-speed communication.

The two brothers had a series of towers built 5 to 10 km apart. At the top of each tower was a tall wooden mast, and they attached one horizontal and two vertical wooden beams to this mast. Claude called this system 'semaphore', which comes from the Greek meaning 'bearing a sign'. 2 ( )

Operators in each tower watched neighbouring towers through a telescope and then passed the message on to the next one in the line. The first line stretched from Paris to Lille, a distance of 2.40 km. 3 ( ). At an average speed of three signals a minute, it was carried in 20 minutes, more than 90 times faster than messengers on horseback.

Once the value of Chappe's system was understood, it soon became the standard method of communication in Europe. 4 ( ). By the time the electric telegraph was developed, France had more than 550 semaphore towers stretching 4,800km.

Unfortunately, Chappe's system had some disadvantages. 5 ( ) The towers were also expensive to maintain and the cost of staff was high. In the end, Chappe was depressed by these criticisms of his inventions and by claims from other engineers that they had invented semaphore, and he committed suicide in 1805.

Question I.The following passage contains ten mistakes. Identify and correct them. (10pts)

If there is one characteristic of British work in the arts that seems to stand out is its shortage of identification with wide intellectual trends. Playwrights and directors can be left-wing in their political lout-out, but the plays they produce rarely convey a straightforward message. The same is largely true of British novelists and poets. Their writing is naturalistic and is not connected to particular intellectual movements. The theatre had always been very strong in Britain, especially in London. The country’s most successful playwrights are those who explore the darker side of the personality and of personal relationships. In contrast, the cinema in Britain is often regarded as not quite part of the arts in all, it is simply entertainment. Britain is unique between the large European countries in giving mostly no financial help to their film industry. Classical music is also a minority interest. British seem disinterested in high education, they watch lots of television, but are enthusiastic readers. The vast minority of books reading in Britain are not classified as serious literature.

Then there was the case of the well-known journalist Luigi Persano, who found completely mad with a jar in front of him. A jar contained a remarkable worm, unknown by science up to that point. Apart from these mysterious cases to which Holmes did not find solution, there are those which various influence people would rather no see on print and those which might affect the reputation of Holmes himself, for whom I have more respectness than for any man alive
