Question

David is ten years old and his cousin is just_. A

David is ten years old and his cousin is just_.
A.twice as older as he
B.aa twice old as he
C.twice his age
D.twice elder than he.
这道题为什么选c呢

Answer 1

as...as只能用原形，排除A答案; twice后加one's 加名词age，表示"年龄是某人的两倍，所以答案C正确。而没有twice加形容词的用法，可以排除BD

追问

the room is three times larger than that one.这个句子和d选项的格式不是一样的么，为什么不能选d呢

追答

哦，你没发现old---older?

追问

？

追答

elder只是特定用在名词brother,sister等的前面

追问

如果把d改成twice older than he这样对吗

追答

对的，还有A改成twice as old as也就对了

追问

也可以说three times his age么

追答

可以，有这样的用法
