答案与题解:

1.A第一段告诉我们窗户因为让阳光进入房间,并且为房间提供热源,所以节约了能源.第二段说,窗户使人们能接触外部世界.所以B,C和D都说明了窗户的重要性.第一段最后一句说,研究者正在实验能让窗户变换亮度,但并没有说已经实验成功,所以A是错误的说法,是正确选择.

2.D短文第三段的第一句说:windowsaretheweaklinkinabuilding,接下来是对这句话分寒冬和炎夏做了说明.所以D是正确选择.

3.C第四段告诉我们,多年来,科学家已研究出多种通过窗户节能的办法,而smartwindows使用的技术使窗户能变换颜色.所以C是正确选择.

4.B第五段第二句提供了答案.asheetofglasscoatedwiththinlayersofchemicalpoundsuchastungstenoxide中的coated是"涂上一层薄薄的..."的意思.

5.C短文最后一段的第五句提供了答案.
