     Herbert answers, "I'm coming!" and goes right back to sleep. I'm not at all like my brother.

     I don't like to go to bed late at night but I don't mind getting up early in the morning.usually

wake up before my mother calls me.I jump out of bed and go into the bathroom to take a shower.

I get dressed, brush my teeth, comb my hair, and get ready to go downstairs for breakfast as soon

as my mother calls.

     But not Herbert. He just sleeps.A military band (军乐队) in our bedroom could not wake

up immediately!"

Herbert out of bed. It's that way every day with my little brother. Perhaps some day he'll learn to

get up on time, but I really don't think so.
