Even though Maria looks very yong ,she is twice _______my twenty_year_old sister .

Aas old as Bolder than Cso old as为什么不选B

谢谢啊

A as old as

虽然Maria看着年轻，但是他比我20岁的妹妹还要大一倍。

也就是三倍，怎么可能看起来young嘛sister 是twenty-year-old，所以是as old as ，如果Maria 是 twice older than 的话，也就是60岁，那他就是多两倍

你好！ Even though Maria looks very yong ,she is twice ___as old as____my twenty-year-old sister . 是正确的。Maria是我那20岁姐姐年龄的两倍，即Maria现在40岁了。 没有twice older than的说法。 twice是两倍于，可以说twice the age of my sister. 如有疑问，请追问。
