Mary is（）（）（）than Tara.

He is （）than（）（）student in his class.

Answer 1

楼上的回答太搞笑。three times older 是指mary的岁数比tera大三倍，而题目里面明明是给的tera的年龄是Mary的三倍。所以正确的答案应该是：
Mary is two times younger than Tera.玛丽的年龄比tera的年龄小两倍。（换句话说就是：tera的年龄比玛丽多两倍）
这里的小两倍也就是是她的年龄的三倍的意思。“比。。。多两倍”=“是。。。的三倍”

He is taller than any other student in his class.
