IV.短文改错(10)

On the morning, my alarm clock didn’t ring, since I woke up an hour late. I was in such a hurry that I burnt my hand when I was cooking the breakfast. Then I ran out of the house to catch the 8:30 buses. This is the bus I usually take. But, you may laugh, I missed it of course.

Our classroom was locked. I realized that moment: It was Sunday.
