解析:句意:粗略估计,尼日利亚是大不列颠的三倍大。我们要表达甲是乙的几倍时,通常用下面三个句型来表示: 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: This rope is twice longer than that one. 这根绳子是那根绳子的两倍长(比那根绳子长一倍)。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。The plane flew ten times as high as the kite. 那架飞机的飞行高度是那只风筝的十倍。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。This hill is four times the height of that small one. 这座山的高度是那座小山的四倍,由题干可知选D正确。
考点: 考查形容词倍数的用法。
