This new machine costs that one.
A. twice as more as
B. as more twice as
C. twice as much as
D. as much twice as
题目解答
答案
C. twice as much as
解析
本题考查倍数比较句型的正确表达。关键点在于掌握“twice as...as”结构的用法,以及much与more的区别。
- “twice as...as”是固定结构,表示“A是B的两倍”,其中形容词或副词直接跟在as之后。
- “as much as”用于修饰不可数名词(如cost),而“more”通常用于比较级(如more expensive)。
- 选项中需排除语序错误(如B、D)和用词错误(如A中的“more”多余)。
选项分析
A. twice as more as
- 错误原因:“as...as”结构中,倍数(twice)已表示程度,无需再加more。正确应为“twice as much as”。
B. as more twice as
- 错误原因:语序错误。倍数twice应放在最前面,且“as...twice as”结构不符合常规用法。
C. twice as much as
- 正确原因:“twice as...as”结构正确,且much修饰不可数名词cost,符合语境。
D. as much twice as
- 错误原因:语序错误。倍数twice应放在句首,而非句中。
