INTRODUCTION TO QUESTIONS
I. Questions with intonations
One of the easiest ways to ask a question that may be answered by yes/no is to raise the pitch of your voice at the end of a statement.
Richard, tu aimes la philosophie ?
Non, je n’aime pas la philosophie.
II. Questions using "est-ce que…?"
Another way to ask a yes/no question is to place est-ce que before a statement. Note that que becomes qu’ before a vowel.
