问题 A new laptop costs about______of a second-hand one.

选项 A、the price of three times
B、three times the price
C、as much as the three times price
D、three times more than the price

答案B

解析 倍数表达题。英语中常用的倍数表示法有(1)主语+谓语+倍数(或分数)+as+adj.+as。例如:I have three times as many as you.(我有你三倍那么多。)(2)主语+谓语+倍数(分数)+the size (amount,length…)of…。例如:The earth is 49 times the size of the moon.(地球是月球的49倍大。)(3)主语+谓语+倍数(分数)+形容词(副词)比较级+than…。例如:The grain output is 8 percent higher this year than that of last year.(今年比去年粮食产量增加8%。)(4)还可以用by+倍数,表示增加多少倍。例如:The production of grain has been increased by four times this year.(今年粮食产量增加了4倍。)本句是第二种表示倍数关系的用法。
