However, since electricity became more and more expensive, people began to pay much more attention to the energy they could get for their houses and the new ways they could find to protect their houses from both cold and heat. Now, houses of an old yet new type have been widely built. In some parts of the world, people share their houses with their livestock.During cold weather, they gather their cows, goats, or other animals and keep them on the first floor of their houses. The reasons are that the animals can be protected from the cold and that they can help to heat the houses as well. The body heat given off by the animals rises to the second floor of the houses, where people live. By sharing their houses with their livestock, people gain a source of heat. People who live in or near cities do not usually keep livestock. However, home builders use the fact that heat rises. This natural law can be used in building houses in these areas. Instead of keeping livestock on the first floor, builders fill it with large rocks. As they are open to the sun’s rays during cold weather, these rocks take in heat. They also give off the heat, and, of course, the warm air rises into the living areas of the houses. So these houses are energy-saving. House-building becomes a great challengeto building designers and energy engineers. They try to meet this challenge by learning from old traditions and by using modern technology. And someday in the future, people will be able to live in more energy-saving houses. 【查看更多】

    　　Walk through the Amazon rainforest today and you will find it is steamy, warm, damp and thick．But if you had been around 15,000 years ago, during the last ice age, would it have been the same?For more than 30 years, scientists have been arguing about how rainforests like the Amazon might have reacted to the cold dry climates of the ice ages, but until now, no one has reached a satisfying answer．

    　　Rainforests like the Amazon are important for mopping up CO2 from the atmosphere and helping to slow global warming．Currently the trees in the Amazon take in around 500 million tones of CO2 each year：equal to the total amount of CO2 giving off in the UK each year．But how will the Amazon react to future climate change?If it gets drier, will it still survive and continue to draw down CO2?Scientists hope that they will be able to learn in advance how the rainforest will manage in the future by understanding how rainforests reacted to climate change in the past．

    　　Unfortunately, getting into the Amazon rainforest and collecting information are very difficult．To study past climate, scientists need to look at fossilized pollen(花粉), kept in lake mud．Going back to the last ice age means drilling deep down into lake sediments(沉淀物), which requires specialize equipment and heavy machinery．There are very few roads and paths, or places to land helicopters and aeroplanes．Rivers tend to be the easiest way to enter the forest, but this still leaves vast areas between the rivers completely unsampled．So far, only a handful of cores have been drilled that go back to the last ice age and none of them provide enough information to prove how the Amazon rainforest reacts to climate change．
