D解析试题分析：考查倍数被动法。倍数表达有四种：1. “A+倍数+形容词或副词的比较级+than+B”， 2.“A+倍数+as+形容词或副词的原级+as+B”， 3. “A+倍数+the size/height/length/width， etc+of+B”， 4. “……times+what+从句”。句意：粗略估计，这个国家是英国的三倍大。故D正确。考点：考查倍数表达法点评：倍数表达要牢记，倍数表达法是高中英语教学的重点，也是历届高考的热点。当我们要表达甲是乙的几倍时，通常用句型来表示：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）。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。4. “……times+what+从句”。如：The production is now three times what it was ten years ago. 现在产量比十年前增加了两倍。
