Every night, after she (完成) dinner, she goes to bed. She always gets up at about ten in the morning. So she is  (真地) fat. Now it's (困难的) for her to walk.

    One day, she goes to  (看) a doctor. The doctor looks over her and then says, "There is something wrong with  (你的) health, Mrs. King. It's not good for you to eat too much meat. You'd better eat a piece of (面包) for each meal."
