答案:B
解析: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”。本题使用的是第3种。句意:新的电脑要花的钱是二手电脑的三倍。故B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.现在的产量比十年前增加了两倍。
