Let’s talk about how to ask and answer closed questions in English.
Closed questions are questions that are answered by ‘yes’ or ‘no’.
Do you like mushrooms?
This is a closed questions, because you can answer, ‘yes, I do’, or, ‘No, I don’t.’
Why do you like mushrooms? This is not a closed question. It’s an open question. It asks for more than a simple yes/no answer.
At first, it can be confusing to know if we need to invert the word order of ‘be’, or if we need to add ‘do’ or ‘does’ to form a question.
Look at the chart below.
What are your observations?

Most English verbs need help to form questions. They need the auxiliary verb ‘do’ before the subject. There are special verbs, like ‘to be’, ‘can’, and ‘will’, that follow different rules. But if you are using a normal verb, in a basic Simple Present question, you need ‘do’.
The 3rd person changes, as usual. But notice where the ‘s/es’ goes. Which subjects change?
