I remember my daughter used to ask questions that girls__would ask.A.twice her age...
I remember my daughter used to ask questions that girls__would ask.
A.twice her age B.twice so old as she C.twice as old as her age 为什么不选C?B改为twice as old as she是不是就对了?

答案

可以看为省略 girls twice her age为 girls who are twice her age
C选项 twice as old as her age是错误的
有固定格式 as twice age as hers
或者the twice as her age
B项so用在否定句,并且比较的为年龄
