题目

you can see—--woman in the photo
中间横线部分选填
A：an 80 years old
B：a 80 years old
C:an 80-year-old
D：a 80-year-old
个人认为可能是A,

答案

选C
80,eighty 是原音音素开头,要用an,所以排除B D
A C从语法上讲,也可以,毕竟没有什么错误,但是不符合英语习惯.
一般情况下,可以有以下几种表达方式：(都是同样的意思,也很常用的)
1.She is an 80-year-oldwoman.
2.She is 80 years old.
3.She is a woman of 80 years.
