then tina told the teacher and the whole class her story. all her classmates laughed loudly after it. some of them said, "poor tina!"
bob, one of tina’s classmates, stood up and said, "well, tina, i’d love to help you. why not let me keep the keys for you? i would put your keys in my backpack."
step ⅴ grammar focus
this activity introduces the target language of this unit. call students’ attention to the sentences on the left. ask four different students to read the four sentences and point out where had plus a past participle is used. write the sentences on the blackboard.
draw a simple time line for each sentence to help students to understand the grammar focus. for example:
 
then get the students to look at the box.
teach students to read the three forms of each verbs first. then ask several students to read the verbs to the class to see if they can read. write the verbs on the blackboard.
ask the students to make sentences correctly using each form of the verbs in the box. for example:
i usually get up at 6:30.
i got up at 5:30 yesterday.
by the time i got up, my sister had already gotten in the shower.
tell the students when we talk about the first thing that happened. we use had plus a past participle （had gotten） and when we talk about the second thing that happened, we use the simple past tense （got up）. ask some to read their sentences to the class.
ask the students to make their own lists of other verbs used in this unit. tell them to put the lists in their notebooks using a three-column format like the one in the look! section. the lists have to include these verbs; leave, walk, start, oversleep, ring, be.
check the answers.
