My uncle✀s brother is (a firefighter) 用三种方法对括号提问 Alice is (eight) 括号提问

买三赠一!每一问给lz四个答案以供挑选><..

对 "My uncle's brother is (a firefighter)" 提问：
1）What does your uncle's brother do?
2）What's your uncle's brother?
3）What's your uncle's brother's occupation?
4）What does your uncle's brother do for a living?

对 "Alice is (eight)" 提问：
1）How old is Alice?
2）What is Alice's age?
3）Is Alice eight-year old or nine-year old?【我承认这问法很awkward==;;;不过想不出别的了，lz轻拍】
4）Hey do you know Alice's twin sister's age?【这种问法更二。。lz可理解为某X追Alice不好意西直接问年龄于是乎通过别人打听自己心上人多大。。lz勿pia】

以上是较美式的说法，英国话估计也不会和这差太大哒～ lz还有任何疑问欢迎追问^^
