more than+倍数词与倍数词+more than
有道题the wings of the plane are ---the lenght of its body答案是B
A twice more than
B more than twice
答
句意：机翼是机身长度的两倍多.
表示倍数方法：
倍数+as +adj/adv + as
倍数 + 比较级
倍数 + the + 名词 + of (这里的名词往往表示长,宽,高,体积或数量等）
如：twice the length of
twice the size of
twice the amount of
A虽然从形式上看似正确,但是表示长度长两倍,应该用twice longer than,而不是more than.
所以只能选B.把more than理解为 “.之多”.
