獎項——聽寫后正確填空者可得BB獎勵

評分規(guī)則：
1、每篇設空十處，難度逐漸增加每答對一空獎勵一個BB。
2、為盡量防止復制答案獲取BB的情況，每題僅對第一位答對的童鞋給予全分獎勵，后面的童鞋將酌情減少獎勵。學習與BB兼得，先到先得，后到后得，歡迎大家涌躍參加哦。

注意：
1、本次活動的難度較前兩次又有所增加啦，請大家仔細聽哦
2、有蟲子反映音頻聽不了，請站內(nèi)聯(lián)系我，我會將音頻發(fā)給你

Heating and cooling equipment are the biggest users of energy in American homes. And homes are responsible for about one fourth of the nation’s total energy use. But there are   （1）   simple ways to deeply cut energy use, its effect on the environment and its cost.
says the design of a passive house aims to reduce energy demand to its lowest possible level. Passive houses use no solar,    （2）   or wind energy equipment. But they are extremely energy    （3）   .
Mr. Peabody says passive houses cut heating and cooling costs by about ninety percent. But what sets his design apart from other "green homes" is that it looks like any other home.
DAVID PEABODY: "That is the beauty of the passive house   （4）   is that you don't have to build in a particular way with any particular materials or to any particular style.  That's why in our case we decided to try to do something to prove that point to make something that was very   （5）   American."
Peabody Architects says it is building the first passive home in the Washington, DC, area. But it will not be the last. In Arlington, Virginia, Roger Lin and his brother Eric are also building one. Roger Lin of Southern Exposure Homes explains that windows are    （6）    and have three layers of glass.
ROGER LIN: "And these are triple-paned."
The windows are airtight. On a cold winter day, the temperature inside the unfinished home is a comfortable twelve degrees, or fifty degrees Fahrenheit.
ROGER LIN: "In here it's above fifty actually. It’s above fifty right now."
David Peabody says you can find passive homes all over the world.
   DAVID PEABODY: "North Africa, for example, has a passive house community designing for very hot dry climates and that's    （7）       of exploration for passive house."
The first passive design was an apartment building in Darmstadt, Germany. Two physicists helped develop it about twenty years ago.
Passive houses use    （8）    . These include precast concrete panels and insulation. They also need to have special    （9）    . Supporters say they cost only about five or eight percent more than traditional homes. But they use ten percent of the energy for heating and cooling.
         （10）          . But Passive House Institute US says even greater savings can be reached with additions like solar water heating systems. They might call that an active passive house.
