Step 2 Presentation

Put a student’s bag into the desk and make a dialogue with the student:

T: Where’s the school bag?

S: It’s in the desk.

Then put the bag on the desk and ask:

T: Where is the school bad now?

S: It’s on the desk.

The teacher write the sentence on the Bb: The school bag is on the desk now. Then ask the student some questions and write down the answers on the Bb again, like:

T: But where was the school bag a moment ago?

S: The school bag was in the desk a moment ago.

Then underline “was” and “a moment ago”.

Ask one student: What do you do every day？

Then write down the key words of the student’s answers on the Bb:

Every day: get up—wash face—go to school—have lunch—do sports

Ask Ss to use yesterday instead of every day to talk about the things they did yesterday and then write down the key words:

Yesterday: got up—washed face—went to school—had lunch—did sports

5. Divide Ss into different groups and discuss the changes because of time and then the teacher help Ss to summarize the concept of the simple past tense: We use the simple past tense to talk about things in the past.
