Step1.Greet the class.
Step2.Lead-in.
In this class, we'll review the six types of tenses. First, let's listen to an English song, The Day You Went Away. Play the song on the computer and show the lyric of the song for the students. Have them listen and look at the lyric, then find out that how many kinds of tenses are used in this song and what they are. Then check the answers with the students.
Step3.Revise the usages of the tenses.
Put up a big card that has a time and tense axis on the blackboard. The axis shows the six types of tenses in the different parts of time(past, now and future). When show the axis, have the students look at the screen. The usages and example sentences are on it.
