     Today was not a good day. Everything went wrong. First, I sleep late and Mom shout at me to wake up.

When I went to the kitchen for breakfast, there was no cereal. I decided to have some toast instead, but I

burned it. I had to eat it anyway because there was no more bread. There was no juice, either. I just had a

glass of water.

     When I was almost at the bus stop, I realized that I had forgotten my wallet, so I had to go back home

and get it. Of course, I missed the bus and had to wait for the next bus.

     I was late for school and the teacher told me to stay in the classroom at lunchtime to catch up on (弥补)

the schoolwork I had missed.

     After lunch, it was the time to give the teacher our homework. I reached into my bag to get it but it wasn't

there. I had left it at home. I was in trouble again.

     When I got home, I went straight to my room to catch up on my homework. Mom cooked fish for dinner.

She knows I don't like fish, but she thinks it is good for her son. It was a horrible day. I hope tomorrow will

be better.
