Mrs. King lives in a big city. She is about {#blank#}1{#/blank#}(四十) years old. She likes to eat meat very much. So her daughter often buys some for her. She doesn't like {#blank#}2{#/blank#}(运动). Every night, after she {#blank#}3{#/blank#}(完成) dinner, she goes to bed. She always gets up at about ten in the morning. So she is {#blank#}4{#/blank#} (真地) fat. Now it's {#blank#}5{#/blank#}(困难的) for her to walk.

    One day, she goes to {#blank#}6{#/blank#} (看) a doctor. The doctor looks over her and then says, "There is something wrong with {#blank#}7{#/blank#} (你的) health, Mrs. King. It's not good for you to eat too much meat. You'd better eat a piece of {#blank#}8{#/blank#}(面包) for each meal."

    "That's {#blank#}9{#/blank#}(容易的), doctor." says Mrs. King. "But when should I eat it? Before a meal or{#blank#}10{#/blank#}(之后) a meal?"

    Do you know the differences between the new buildings and the old ones?

    Old buildings h {#blank#}1{#/blank#} brick and stone walls. The walls hold up the buildings. In cities, many modern buildings l {#blank#}2{#/blank#} as if they are made just of windows.

    Walls of dark glass reach high into the air. Many buildings are m {#blank#}3{#/blank#} than 50 stories tall.

    Are walls of glass strong e {#blank#}4{#/blank#} to hold up the new building? No. The new glass walls do not hold up the buildings, but they only cover up the frame made of steel. Have you ever watched a new building going up? The steel frame is built f {#blank#}5{#/blank#} . Then the glass walls are hung on the frame. When the building is f {#blank#}6{#/blank#} , the frame does not show. The outside looks like windows without walls. The glass walls s {#blank#}7{#/blank#} in the sun with no decoration. Many people find them beautiful just as they are.
