If a man has a good appetite (胃口), it is thought that he is healthy. When we hear a boy saying, "I'm a{#blank#}1{#/blank#} hungry as a bear." We are quite sure that he is well.

    It is a good sign to feel hungry in fact. The body rings the bell to tell us that it needs food.

    If a boy did not eat, he would grow t{#blank#}2{#/blank#} and weaker day by day until he was unable even to walk and at last, he would stop living entirely (完全地). That is what happens when people starve (挨饿) to death.

    You should know the following things about eating.

    Firstly, you should eat e{#blank#}3{#/blank#} leafy vegetables and some fruit every day and have g{#blank#}4{#/blank#} of water among meals during the day. They can provide the energy we need and they are really helpful for us to grow.

S{#blank#}5{#/blank#} , you should eat three meals a day and be regular. Don't eat between meals. And eat slowly and chew the food until it is soft. Chewing carefully is really good for your stomach. Never d{#blank#}6{#/blank#} water or milk in the middle of chewing.

    At last, you should stop eating food w{#blank#}7{#/blank#} you don't feel hungry. If you eat too much, it is truly not good for your health.
