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.

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

I have a briefcase full of papers which describes cases Sherlock Homes has investigated. Some are failures since there were some final explanations for the mysteries in question. A problem without a solution may interest the specialist, but will offer little to the general reader. Among these finishing stories is that of the yacht Alicia, which one morning sailed into the mist and disappeared forever; the vessel along the crew were never seen again. 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

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.

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

Giup minh vs nha!!

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.

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.
