解析：句意：新的教学大楼是黄色的那一个的。这里问倍数，倍数的表达有三种：1. “A+倍数+形容词或副词的比较级+than+B”，表示“A比B大（长、高、宽等）多少倍”。如：The car runs twice faster than that truck. 这辆小车的速度比那辆卡车快一倍（是那辆卡车的两倍）。2.“A+倍数+as+形容词或副词的原级+as+B”，表示“A正好是B的多少倍”。如：Asia is four times as large as Europe. 亚洲的面积是欧洲的四倍。 3. “A+倍数+the size/height/length/width, etc+of+B”，表示“A正好是B的多少倍”。如：This street is four times the length of that one. 这条街是那条街的四倍长。在四个选项中，只有B符合。
考点: 考查倍数的用法。
