This is a review for ESL students.
Students always get confused between using to be/do.
an answer: Yes, I was late.
Students often think that the question is with a regular helping verb "do" and they write: Do you late?*
This power point is a review of the Present Simple and Past Simple with an emphasis on when to use was/were/am/is/are and when to use do/does/did in positive and negative sentences and in questions.
It is a whole lesson and includes a few exercises in the middle and two final exercises. One of the exercises is an interview in pairs.
