Hello there! As a language expert with a keen interest in grammar and syntax, I'm here to help clarify your question about the use of hyphens in the context of age descriptions. The use of hyphens can be a bit tricky, but understanding the rules can certainly help in crafting clear and grammatically correct sentences.

When it comes to the age of a person or an object, there are two primary ways in which the term "years old" can be used: as an adjective or as a noun. The decision to hyphenate depends on the role it plays in the sentence.

**Step 1: Using "Years Old" as an Adjective**
When "years old" is used as an adjective, it typically comes directly before the noun it modifies. In this case, it is customary to hyphenate the phrase. The hyphen serves to link the age to the noun, making it clear that the age is a descriptor of the noun that follows. For instance:

- My eight-year-old neighbor wrote a poem about commas for National Grammar Day.

In this sentence, "eight-year-old" is an adjective that describes the neighbor. The hyphen is used to show that the neighbor is eight years old.

**Step 2: Using "Years Old" as a Noun**
When "years old" is used as a noun, it is often part of a compound noun, and it is also hyphenated. This is because the hyphen helps to indicate that the words are working together to form a single idea. For example:

- That 70-year-old with the purple hoodie loves Justin Bieber.

Here, "70-year-old" is a compound noun that refers to a person who is seventy years old. The hyphen is used to connect "70-year" and "old" into a single descriptive term.

Step 3: Exceptions and Clarifications
It's important to note that there can be exceptions to these rules, especially in informal writing or speech. Some people might choose not to hyphenate "years old" in certain contexts, but for the sake of clarity and adherence to standard written English, hyphenating is the preferred choice when "years old" is functioning as an adjective or a compound noun.

Now, let's move on to the translation of the above explanation into Chinese.
