Step1 Warming up.
Enjoy a song：Yesterday once more
T:What did you do just now？
What did you do yesterday？(talk in pairs，then ask and answer)
T: Did you have an English lesson yesterday？
Ss:Yes.

T: In the passage，we used differents kinds of tenses.(PPT呈现)。Bcause when we talk about the things to“in the past”,we should use the past tense. when we talk about the things“now”,we should use the present tense.
Step2：Presentation and practice.
一．Grammar time
When we used the past tense, where should we put the verbs in the sentence?(板书句子Six years ago，I couldn’t write.)
T: “Six years ago”tells us “when”
“I” tells us “who”
“could’t write”tells us “what”(So we should use the verb in this part)
Let’s read grammar time by yourselves，you will learn more bout the past tense.
Here are the irregular word. Can you find more irregular words？
4.Play a game（Quick response）
T: I say the words, you should say the past tense as quickly as you can.
5.Play a game : Make sentences
T: Work in groups of four. The first student writes down “When”, The second student writes down “Who”and the third student writes down “What”. The fourth student need to put these three arbitrary combined into a sentence .
Eg: S1: twenty years ago
S2: Mr Brown
