Read the follwing passage and mark the letter A, B, C or D on your answer sheet to indicate the correct answer to each of the questions.The rules of etiquette in American restaurants depend upon a number of factors the physical location of the restaurant, eg., rural or urban; the type of restaurant, eg., informal or formal; and certain standards that are more universal. In other words, some standards of etiquette vary significantly while other standards apply almost anywhere. Learning the proper etiquette in a particular type of restaurant in a particular area may sometimes require instruction, but more commonly it simply requires sensitivity and experience. For example, while it is acceptable to read a magazine in a coffee shop, it is inappropriate to do the same in a more luxurious setting. And, if you are eating in a very rustic setting it may be fine to tuck your napkin into your shirt, but if you are in a sophisticated urban restaurant this behavior would demonstrate a lack of manners. It is safe to say, however, that in virtually every restaurant it is unacceptable to indiscriminately throw your food on the floor. The conclusion we can most likely draw from the above is that while the types and locations of restaurant determine etiquette appropriate to them, some rules apply to all restaurantWhich of the following words is most similar to the meaning of “rustic” in line 7?

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.     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 they 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. The word "they” in paragraph 2 refers to __________.

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 31 to 35.Korea's recent unveiling of the world's first cloned dog was welcomed by King Chow, assistant professor of biotechnology at the Hong Kong University of Science and Technology, but he also warned that we need to be on guard against possible reproductive cloning. Professor Chow went on to explain that, “The development of the technology is a good thing in itself but how we monitor it and who we allow to use it will be of great importance”.Professor Chow is one of many academics who feel that a clear line must be drawn between reproductive cloning and therapeutic cloning. Therapeutic cloning involves the use of embryonic stem cells to develop human cells or organs that can be used to cure diseases such as Parkinson's and diabetes. People in wheelchairs may be able to walk again thanks to this technology as scientists believe that they can clone new cells to repair back and neck injuries.Reproductive cloning involves implanting a cloned embryo into a uterus in the hope of producing a healthy foetus. A company called Clonaid claims to have successfully cloned thirteen human babies. They say that all of the babies are healthy and are in various locations, including Hong Kong, UK, Spain and Brazil. Clonaid states that they are using human cloning to assist infertile couples, homosexual couples and families who have lost a beloved relative.The same technology can be used for animal cloning. If endangered species such as the giant panda and Sumatran tiger could be cloned, they could be saved from extinction. Livestock such as cows could also be cloned to allow farmers to reproduce cattle that produce the best meat and most milk. This could greatly help developing countries where cows produce significantly less meat and milkThe word “it” in paragraph 1 refers to ______.
