    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).

    B. For nearly a week.

    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.

    A field
    B. A hospital
    C. A library
    D. A restaurant

    Your brain controls everything you do. It makes it possible for you to think, learn, create and feel; to blink(眨眼) and breathe and for your heart to beat-this fantastic control center is your brain. It is so amazing that a famous scientist once called it “the most complex(复杂) thing we have discovered in our universe”.Can this small grey organ(器官), which weighs less than one and a half kilos, really do so much? Amazingly, your brain contains(包含) about 100 billion neurons(神经元)-it would take you over 3,000 years to count them all. Believe it or not, the activity in your brain never stops. Your neurons create and send more messages than all the phones in the world. And although one neuron creates only a little electricity, all your neurons together can produce enough electricity to power a light bulb (灯泡).So exactly how fast does your brain work? Well, imagine this: a bee lands on your foot. Neurons in your skin send this information to your brain at a speed of more than 240 kilometers per hour. Your brain then uses other neurons to send the message back to your foot to shake the bee off quickly. These neurons can send this information at more than 320 kilometers per hour. No computer has your brain’s unbelievable ability to deal with the amount of information coming from your eyes, ears and other sensory(感觉的) organs.But how does your brain allow you to learn things that you will use in the future? The structure (结构) of your brain changes every time you have a new thought, remember or learn something. For example, riding a bike seems impossible at first, but soon you are able to do it. How? As you practice, your brain sends “bike riding” messages again and again. Soon, the actions are learnt and you are able to ride a bike easily from then on. (6.0) (1). [单选题] (2分) From the passage we know that neurons __________.

    A. receive messages very slowly
    B. are only found in your skin
    C. send messages to your brain
    D. need electricity to work
