Yes/No Questions
There are two ways to form yes/no questions in Mandarin, and both of them are pretty different from how things work in English.
The first way is to add the question particle 吗. This effectively turns a sentence into a question as follows:
我喜欢那家餐厅. 他们喜欢那家餐厅吗? |
I like that restaurant. Do they like that restaurant? |
The second way is to essentially ask verb-not-verb
这是不是一家餐厅? |
Is this a restaurant? |
Remember, we negate 有 with 没 like so:
你有没有我的书? |
Do you have my book? |
