Hey, friends! Have you ever heard {#blank#}1{#/blank#} my grandfather, Mr Sun? He is {#blank#}2{#/blank#} to speak three languages: Chinese, English and French. My grandfather is a good{#blank#}3{#/blank#} . If there is something wrong with your teeth, you can go to see my grandfather. Last year my grandfather retired. He {#blank#}4{#/blank#} my city and went to the countryside. He built a small house and lived there {#blank#}5{#/blank#} . Well, I found my grandfather never felt {#blank#}6{#/blank#} in the countryside. In fact he had a great time. Every day many old people went to see him. When the{#blank#}7{#/blank#} was sunny and warm, they usually sat under the tree in front of his house. They talked {#blank#}8{#/blank#} watched his cat climbing the tree. And they {#blank#}9{#/blank#} his parrot sing in the tree. If you also visit his house in the countryside, you'll {#blank#}10{#/blank#} in love with it. Next weekend I'll go to see him.
