Passage3

  What will the house of the future look like?Could it have gardens on its walls,or a pool with fish for dinner?Architects(建筑师)believe that they are all possibilities.The only thing for sure is that the house will be as green as possible.

  The tree house

  Many architects in the world would like to build a “tree house”.Like a leaf ,the surface of the house collects sunlight during the day .The energy can be used to heat water,produce electricity,and even create fresh air for the home .The “root(根)”of the house is deepunder the ground so that it can control（控制）the home's temperature.

  The lizard（蜥蜴）house

  Like a lizard,changing colour with the weather is the most important design of a lizard house,When it's in the bright sun,the cover of the house will turn dark to protect it fr om strong heat .During dark days,it rurns white and takes in as much light and heat as possible to produce energy.

  Meals at home

  The future of food production is taken as one part of the design of the building.Gardens may appear on the outside walls of the house .People can plant tomatoes,carrots and green tea on them.So every day in the morning,you just need to walk outside and collect your meals.

  Learning form the past

  Looking to the future isn't the only way to be green.Sometimes,ancient techniques(技术)can also help cut down energy use .For example,a chimney(烟囱)can be a useful air conditioner because it is easier for hot air to flow out of the chimney.
