问题 Just as glass windows offer buildings both light and insulation, certain atmospheric gases (i)______incoming sunlight and (ii) ______ heat radiated from the ground, preventing warmth from escaping.

选项

答案B,F

解析 Just as说明前后同义重复;逗号说明同义重复。前文说offer buildings light(为建筑提供光),所以第一空填入带有“允许”意味的词即可。deflect使偏向,admit允许进入,conduct传导。答案选B。后文说preventing warmth from escaping(阻止热量散逸),所以填入一个带有“阻止”意味的词即可。dispense分配,contain防止……的蔓延,transmit传送。答案选F。
