step2 presentation  
t： here is an article, can you find out how many tenses are there in this article?
    today is fine, the sun is shining brightly and it is a beautiful sunny day. i always get to school at 7 o’clock everyday, but i was late today because i couldn’t find the key to my bike. i think i will take a taxi to go home tonight.
(let the students think of the simple present tense, simple past tense, present continuous tense and simple future tense, write down the rules)
compare the present continuous tense with the past continuous tense for the ss, let them find out the differences. then tell them when to use the past continuous tense.

step3 practice (game time)
t: today we’ll learn the past continuous tense. first can you help me to find my key? the taxi is so expensive and i really want to enjoy the pretty day on my bike. i might leave my key somewhere and maybe someone took my key away. you can ask me questions to help me find my key.

t: i was having dinner at 6:30p.m. last night. what was my father doing at that time?
do it for several times with the children and then let them try to make up sentences with the information in the timetable.

what was our teacher doing…?
what was her father/ her mother/ her little dog doing from… to…?
(let the students ask these questions to practice the past continuous tense)

then the teacher asks:
was i having a shower at 6:00p.m.?
