Which of the following italicized phrases is INCORRECT?

A、 This house is three times the size of that one.
B、 My cup is twice bigger than yours.
C、 The dictionary is five times more expensive.
D、 Our factory is as twice big as theirs.

【正确答案】 D

【答案解析】考查倍数表达法。常见倍数表达结构有“A+be+倍数+the+计量名词(length，height，depth，size，etc．)+of B”，“A+be+倍数+形容词比较级+than B”或“A+be+倍数+as+形容词原级+as B”等，A、B、C表达均符合规则，只有D错误，twice应放在as之前。
