B.three times large than

D.three times the size of

答案:

题目分析: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。

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。
