I cleaned my room last Saturday morning.
I washed my clothes last Saturday afternoon.
I cooked a meal last Sunday evening.

(3) 教师在课件上呈现两组句子，引导学生认真观察，并尝试找出规律。
What do you usually do on weekend? What did you do last weekend?
I clean my room. I cleaned my room last Saturday.
I wash my clothes. I washed my clothes last Sunday.
