　　Step 3： Presentation

　　1.     Put some word cards on the blackboard and learn them.

　　2.     Explain to the students that many verbs in English are regular. That means they follow a pattern or rules. To form the third person singular of regular verbs， we add ‘-s’ to the infinitive. We add ‘-es’ to verbs that end in ‘-s’， ‘-sh’， ‘-ch’， ‘-x’ or ‘-o’.

　　3.     Most irregular verbs also form the third person singular in the same way. There are some special verbs such as “be” and “have” and the third person singular form of the verbs have to be learned， i.e. “is” and ‘has’.

　　4.     To make the verbs in the third person singular negative， we use the auxiliary， or helping verb “does” plus ‘not’ and the infinitive， e.g. doesn‘t play， doesn’t swim. The auxiliary ‘do’ is also used in ‘wh’ questions， e.g. ‘What does he do？’ ‘do’ is used to form closed or ‘yes /no’ questions.
