试题分析:考查倍数表达法:这题使用的是:“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”。句意:大约110百万的人搬到这个城市,人口是10年前的两倍。选B。
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. 现在的产量比十年前增加了两倍。
