Read the passage and then choose the best answer.

The British ship H.M.S Breadalbane sank in the Canadian Arctic on August 21 1853, after being crushed by encroaching ice while on a rescue mission. The 31 crewmen aboard escaped over the ice to a companion vessel as the Breadalbane went down in 15 minutes.

Canadian scientists now report that after a three-year search of records about the ship, they have located it sitting upright in 110 meters of water. Using a robot camera device, they said they have taken remarkably clear pictures of the Breadalbane, which has been well preserved by the ice and the supercold water "What we have is a treasure trove of 19th century Arctic exploration." reported one scientist. Located 1000 kilometers above the Arctic Circle, the Breadalbane is the world's northernmost known shipwreck.

  1. According to the passage, the Breadalbane was sailing where it was on August 21, 1853, mainly to
    A. explore the area in which it sank. B. defend that area for the British government.
    C. find a northwest passage to the Orient. D. save the lives of other people.

  2. What happened to the Breadalbane's crew?
    A. Some survived but most perished. B. Most survived but a few perished.
    C. All perished in the accident. D. All were rescued by another ship.

  3. The scientists can prove they have found the exact location of the Breadalbane because they
    A. have taken underwater photos of the ship.
    B. dived down to the wreck to explore it
    C. managed to refloat the boat using modern engineering techniques.

D. retrieved some objects from the wreck with the ship's name on them.

  1. The reason that the scientists called the wreck a "treasure trove" is that they expect it to yield a lot of

A. precious metals. B. valuable foreign goods. C. precious stones. D. valuable information.

  1. The main reason that they can be sure to expect to learn a great deal about 19th century Arctic exploration from the wreck is that
    A. no other ship ever sank in waters so far north.
    B. water currents are gentle there so the ship was not moved.
    C. the camera they are using is a robot.
    D. the ship has been extremely well preserved by the severe cold.

  2. The principal historical distinction of this wreck when compared with other is that
    A. it has lain underwater for so long.
    B. the scientists expect to become wealthy from its discovery.
    C. no other has been found so far north.
    D. until now it has been impossible to take pictures in such icy waters.

Read the paragraphs below and the summary which follows. (3ms)

Air pollution is a cause of ill-health in human beings. In a lot of countries there are laws limiting the amount of smoke which factories can produce. Although there isn’t enuogh information on the effects of smoke in the atmosphere, doctors have proved that air pollution causes lung diseases.

The gases from the exhausts of cars have also increased air pollution in most cities. The lead in petrol produces a poisonous gas which often collects in busy streets surrounded by high buildings. Children who live in areas where there is a lot of lead in the atmosphere can’t think as quickly as other children and are clumsy when they use their hands.

There are other long-term effects of pollution. If the gases in the atmosphere continue to increase , the earth’s climate may become warmer. A lot of the ice near the Poles ma melt and may cause serious floods.

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.
