[Q]: Article: Students at the Yale School of Architecture handed over the keys to a house that they designed and built to its new owners at a ceremony on Sept. 25 at 20 King Place. The ceremony held to hand over the house will mark the completion of the school's First-Year Building Project 2008. since 1967, the Yale School of Architecture has offered its first-year graduate students the opportunity to design and build a structure as a part of their education. Unique among architecture schools, this program is compulsory for all members of the class, and students frequently refer to it as their reason for applying to Yale. This year's class of 64 worked to design, develop and document an idea for a 2,100-square-foot, wheelchair-accessible, two-family house. Students had to use sustainable resources and energy-efficient technology. The budget for the project is always less than actual construction costs, and the builders-in-training had to seek supplementary donations, mostly in the form of construction materials. The result this year was a "designer" home, dressed entirely in cedar , fitted inside with Swedish-designed cabinetry and partially powered by solar energy. The floors are bamboo, another natural material prized for being quickly replenished . This year, the student-builders used a pre-cast foundation system, which, in addition to its other labor-saving virtues, uses 75% less concrete than the poured system. The first-year class of 2008 raised $100,000-worth of donated materials. But when it came to constructing the inside steps of the house, they used old drafting tables from the School of Architecture that would otherwise have been thrown out. Ground was broken in May for the house at King Place, and the whole class worked on site until the construction was finished.
Answer: to increase their interest in architecture
[A]: The students at the Yale School of Architecture designed and built the house _ .

[Q]: Article: The United States is faced with serious traffic problems. Too many cars travel on the freeways to and from the city. This heavy traffic causes delays and lots of pollution from cars that are using their engines but not moving anywhere. Many cars going nowhere is called a "traffic jam." While many cities in the United States have traffic problems, some of the worst are in Los Angeles, California. Los Angeles is a big city with a large downtown area. One of the reasons why there is so much traffic is that few people use public transportation to get around Experts say one possible solution to the traffic problem in Los Angeles would be to make people want to use the public transportation system of buses instead of their own cars. People say the buses should be made easier, faster, less costly and more dependable than driving a car. One suggestion is to reduce the cost of riding the bus. People who usually drive their cars could save a lot of money on gas and parking costs. Also, Los Angeles could make the buses easier for people to use. The buses could travel to more places in the city. And there could be more special lanes on the freeways that only buses could drive in. These changes would make taking the bus faster and easier than driving a car. Other experts have said that the best way to ease traffic problems is to charge people money to drive on the freeways. These charges, or tolls, would be for the most crowded roads. The tolls would be in effect during the times of day when most people drive to work and home again. These times in the morning and late afternoon are called "rush hour". People would try to avoid driving on these roads, which would decrease the amount of traffic. Also ,the money collected from these tolls could be used to improve the roads and public transportation system.

[Q]: Article: We have only one earth.In a world with limited land, water and other natural resources, the harm from the traditional business model is on the rise.Actually, the past decades has seen more and more forests disappearing and globe becoming increasingly warm.People now realize that this unhealthy situation must be changed, and that we must be able to develop in sustainable ways.That means growth with low carbon or development of sustainable products.In other words, we should keep the earth healthy while using its supply of natural resources. Today, sustainable development is a proper trend in many countries.According to a recent study, the global market for low-carbon energy will become three times bigger over the next decades.China, for example, has set its mind on leading that market, hoping to seize chances in the new round of the global energy revolution.It is how trying hard to make full use of wind and solar energy, and is spending a huge amount of money making electric cars and high-speed trains.In addition, we are also seeing great growth in the global markets for sustainable products such as palm oil , which is produced without cutting down valuable rainforest.In recent years the markets for sustainable products have grown by more than 50%. Governments can fully develop the potential of these new markets.First, they can set high targets for reducing carbon emissions and targets for saving and reusing energy.Besides, stronger arrangement of public resources like forests can also help to speed up the development.Finally, governments can avoid the huge expenses that are taking us in the wrong direction, and redirecting some of those expenses can accelerate the change from traditional model to a sustainable one. The major challenge of this century is to find ways to meet the needs of growing population within the limits of this single planet.That is no small task, but it offers new chances for sustainable product industries.
