As well as yes / no questions, you can also form tag questions with 吗 (ma). Tag questions are quick questions that are tagged on the end of a sentence to ask for /confirm/iation. In English, this is often done with "right?", or by adding the negative form of the verb phrase - e.g., "isn't it?".
The easiest way to do this in Chinese is to add an adjective and 吗 on the end of the sentence.
Basic Pattern
1. ……， 好 吗？ ..., all right?
2.……， 对 吗？ ..., right?
3.……， 是 吗？.., is that it?
4.……， 可以 吗？ ..., is that OK?
By placing these on the end of a sentence, you can soften a suggestion or request /confirm/iation.
