In modern society, living without money sounds almost impossible. However, that’s exactly what an Australian couple from a big city has been doing for nearly a whole year.Rachel Newby, 25, and Liam Culbertson, 27, have come up with creative ways of making it through the year without spending any money. They built themselves a new house. The house was made of used wood and recycled materials. They grew their own food, and at times they didn’t hesitate(犹豫) to look for food in the dustbins (垃圾箱).But this year has been quite difficult. The soil(土壤) in their garden was too poor to grow vegetables. The climate there was terrible as well. They kept moving their home till they finally lived in a 2.5-square(平方)-meter house. They collected cold rainwater to take a shower. What’s worse, they had to share a toilet with the rest of the community.Even though they had no jobs, they didn’t have a lot of free time to waste. They spent most of the day working for local farmers planting vegetables and picking fruit so that they could earn their next meal. They had five ducks that could provide them with fresh eggs. But when there wasn’t enough food for them, they had to go to look for food in the dustbins.Not everyone is brave enough to do this. But they really made it work and they felt happy. (8.0) (1). [单选题] (2分) How long does the Australian couple live without money?
Smoking in indoor public places including public working places, public transport vehicles(车辆) and some other special outdoor working places has been banned(禁止) in China since January 2011. Let’s look at the following advantages of banning smoking.First, banning smoking will not only help in saving smokers from health problems and diseases, but will also be good for passive(被动) smokers. When the smoker is smoking in a restaurant, the people around him are sure to breathe(呼吸) in the smoke and suffer(受苦,患病) from the diseases an active smoker gets. If smoking is banned, spread of these diseases can be controlled(控制). Next, banning smoking will put stress on smokers to give up. Since a smoker is prevented from smoking, he will learn how to live without smoking for long hours. When a smoker doesn’t smell or see anybody around him smoking, it might reduce his wish to smoke too. As a result, people have to give up smoking.Smoking in public places influences non-smokers to start smoking, especially adolescents. When teens see people around them smoking, they will follow them. Thus the number of teen smokers will increase. Also asthma(哮喘) and other problems are often seen in children living around smokers. So if it is banned, these places will become safe for children and teenagers.Smoking should be banned to increase work productivity(生产率). Employees(雇员) who smoke usually take breaks to smoke while working. So the number of hours they put in their work is smaller.If you see from the environment point of view, smoking should be banned. Smoking causes air pollution. If it is banned, it will help keep the environment from getting worse. (8.0) (1). [单选题] (2分) __________ isn’t a non-smoking place.
