How do we start?
That is a question, but not the kind we will be discussing today. Today we will use verbs that we put in front of the sentence, instead of the interrogative pronouns: 'Why, Who, What, Where, When, How'. In school, you always ask questions when you don't understand something in class.
The verb 'to do' is often used to form a question sentence. Don't forget with he/she/it there comes -es after do: does. The verb after 'does' does NOT get an -s, because it's already in the sentence.
"She has a brother." ► "Does she have a brother?"
"Do you like dogs?"
You can also switch the subject and the verb in the sentence to create a question stentence.
"I can help you." ► "Can I help you?
"He is smart." ► "Is he smart?"
