General:
* 你 的 ... 是 什么？ (nǐ de ... shì shénme?) - This is the most basic structure, meaning "Your... is what?" You would replace "..." with the specific thing you're asking about.
Specific examples:
* 你的名字是什么？ (nǐ de míngzi shì shénme?) - What is your name?
* 你的年龄是多少？ (nǐ de niánlíng shì duōshǎo?) - What is your age?
* 你的爱好是什么？ (nǐ de àihào shì shénme?) - What are your hobbies?
* 你的工作是什么？ (nǐ de gōngzuò shì shénme?) - What is your job?
* 你的电话号码是多少？ (nǐ de diànhuà hàomǎ shì duōshǎo?) - What is your phone number?
Remember:
* You can use the structure "你 的 ... 是 什么？" for almost any question starting with "What is your...".
* The word order is important in Chinese. "你的" (your) always comes before the noun you're asking about.
* The tone of your voice can also convey your meaning. For example, a rising tone at the end of the sentence can make it sound like a question.
