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 35 to 42.

The green building movement, started in the 1970s as a way to reduce environmental destruction, is changing the way buildings are constructed. In the early years, green builders were a small minority, and their goals of reducing the environmental impact of buildings were considered unrealistic. Now, however, the movement is growing, as builders have been able to take advantage of new technology.

Green builders try to make use of recycled materials, which means less waste in dumps. Also, they reduce environmental impact by reducing the energy requirements of a building. One way is to provide an alternative, non-polluting source of energy. First, with solar panels, it is possible to produce electricity from the rays of the sun. Once installed, they provide energy at no cost and with no pollution.

Another solution is to reduce the amount of energy required in a building. It is possible to cut electricity use noticeably by improving natural lighting and installing low-energy light bulbs. To reduce the amount of fuel needed for heating or cooling, builders also add insulation to the walls so that the building stays warmer in winter and cooler in summer.

One example of this advanced design is the Genzyme Center of Cambridge, the most environmentally responsible office building in America. Every aspect of the design and building had to consider two things: the need for a safe and pleasant workplace for employees and the need to lessen the negative environmental impact. 75 percent of the building materials were recycled materials, and the energy use has been reduced by 43 percent and water use by 32 percent, compared with other buildings of the same size.

In other parts of the world, several large-scale projects have recently been developed according to green building principles. One of these is in Vauban, Germany, in an area that was once the site of army housing. The site has been completely rebuilt with houses requiring 30 percent less energy than conventional ones. These houses, heated by special non-polluting systems, are also equipped with solar panels.

A larger project is under way in China. The first phase of this project will include houses for 400 families built with solar power, non-polluting bricks, and recycled wall insulation. In a second phase, entire neighborhoods in six cities will be built. If all goes well, the Chinese government plans to copy these ideas in new neighborhoods across China.

Green building ideas, on a small or large scale, are spreading. Individuals, companies, and governments are beginning to see their benefits. Not only are they environmentally friendly, green buildings improve living and working conditions and also save money in the long run.

(Adapted from “Advanced Reading Power” by Beatrice S. Mikulecky and Linda Jeffries)

C. Being friendly to the environment: Thân thiện với môi trường

D. Increasing work productivity: Tăng năng suất lao động

Dẫn chứng (đoạn 7): Not only are they environmentally friendly, green buildings improve living and working conditions and also save money in the long run: Không chỉ thân thiện với môi trường, các cao ốc xanh còn cải thiện điều kiện sống và làm việc, và tiết kiệm tiền về lâu dài.

A. They have only been built in technologically developed countries: Chúng chỉ được xây dựng ở các quốc gia phát triển công nghệ

B. They are gaining in popularity in different parts of the world: Chúng đang trở nên phổ biến ở nhiều khu vực trên thế giới

C. They are environmentally responsible constructions with gardens: Chúng là những công trình thân thiện với môi trường có các khu vườn

D. They are more economical and produce no pollution: Chúng tiết kiệm hơn và không gây ô nhiễm

Dẫn chứng (đoạn 7): Green building ideas, on a small or large scale, are spreading: Các ý tưởng về cao ốc xanh ở quy mô to hay nhỏ đều đang lan rộng.

Dựa vào dẫn chứng trên cùng các ví dụ ta trong bài có thể thấy rằng cao ốc xanh đang ngày càng phổ biến ở nhiều nơi trên thế giới. Vậy chọn đáp án đúng là B.

Phương án A, C sai vì không được nhắc đến trong bài, phương án D sai vì các cao ốc xanh chỉ giảm thiểu ảnh hưởng đến môi trường chứ không phải “không gây ô nhiễm” hoàn toàn.

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 36 to 42.

Forces other than damaging winds are also at work inside tornadoes. Sometimes, as the writhing, twisting funnel passes over a house, the walls and ceiling burst apart as if a bomb had gone off inside. This explosion is caused by the low air pressure at the center of a tornado.

The pressure at the center of a tornado is usually 13 pounds per square inch. However, inside the house, the air pressure is normal, about 15 pounds per square inch. The difference of 2 pounds per square inch between the inside and outside pressure may not seem like much. But suppose a tornado funnel passes over a small building that measures 20 by 10 by 10 feet. On each square inch of the building, there is 2 pounds of pressure from the inside that is not balanced by air pressure outside the building. On the ceiling, that adds up to an unbalanced pressure of 57, 600 pounds. The pressure on the four walls adds up to 172,800 pounds.

If windows are open in the building, some of the inside air will rush out through them. This will balance the pressure inside and outside the building. But if the windows are shut tightly, the enormous inside pressure may cause the building to burst.

Unfortunately, heavy rain and hail often occur in thunderstorms that later produce tornadoes. So people frequently shut all windows to protect their property. This may cause far worse damage later. For the same reason, tornado cellars must have an air vent. Otherwise, the cellar door might be blown out when a tornado passes over it.

Which of the following is the main topic of the passage?

A. How tornadoes can be prevented

B. When tornadoes usually occur

C. Where tornadoes are formed

D. Why tornadoes cause so much damage

B. Successful green building projects all over the world: Các dự án cao ốc xanh thành công trên toàn thế giới

C. An environmentally friendly approach to constructing buildings: Một cách tiếp cận thân thiện với môi trường trong việc xây dựng các tòa nhà

D. Economic benefits of environmentally responsible buildings: Lợi ích kinh tế của các tòa nhà thân thiện với môi trường

Ta thấy đoạn đầu bài văn nói về việc phong trào xây dựng các cao ốc xanh đang phát triển còn các đoạn văn sau phân tích chi tiết việc các nhà xây dựng đã và đang cố gắng xây dựng các tòa nhà thân thiện với môi trường. Như vậy đáp án đúng ở đây là C.

Các phương án còn lại hoặc quá chi tiết hoặc chưa nêu ra được đối tượng chính là xây dựng các tòa nhà thân thiện với môi trường.
