用英语介绍年龄？age和year old可用于准确的年龄，其句型为：A：one’s age(s)+be+数字 如：1.My age is nine.我的年龄是9岁。2.Their ages are 8，7，and 6. 他们的年龄是8岁，7岁和6岁。B：人+be+数字+（years old）如：1.My brother is ten （years old）.我弟弟10岁了。那么，用英语介绍年龄？一起来了解一下吧。
There are three ways to express age in English:
1. Ones age (plural) + be + number: "My ages are nine."
2. Person + be + number + years old: "I am thirteen years old."
3. Number-year-old: "I am a 13-year-old."
The common method of expressing age in English usually involves using cardinal numbers directly, for example:
- "Her daughter is eighteen." (Her daughter is 18 years old.)
Or using "cardinal number + years old," sometimes replacing "years old" with "years of age":
- "Her daughter is eighteen years old." / "Her daughter is eighteen years of age."
Alternatively, the structure "cardinal number - year - old" can be used, often as a (predicative) attributive:
- "Her 18-year-old daughter is now in university."
For expressing age at a specific time, use "at the age of + cardinal number":
- "Her daughter got married at the age of eighteen."
The structure "of + cardinal number" can be used as a postpositive attributive:
- "Her daughter is now a pretty girl of eighteen."
Or use "aged + cardinal number" for a similar meaning, also as a postpositive attributive:
- "Lying on the floor was a boy aged about seventeen."
Finally, "be in one's + tens plural" can be used to indicate an approximate age:
- "He went to the United States in his fifties."
Note: The possessive form "my ages" should be changed to "my age" since age is an uncountable noun. Also, ensure the subject-verb agreement is correct, such as "I am" instead of "I am." The structure "13-year-old" should be hyphenated, and "now in university" should be "now in college" to match the common usage in English.

1 年龄作定语的时候，中间接连接线，比如：他是一个20岁的男孩 应写为
he is a 20-year-old boy.
2 当年龄作状语的时候，不加连接线，如：她今年20岁 写为
she is 20 years old.
当然楼上的写法也都对，at the age of 也经常用，如 my grandma is at the age of 86. 但是 my age is 20这种不是很常用。

B：人+be+数字+（years old）
