    n America hitching a ride(搭便车) is very common. Many people there love hitching a ride during{#blank#}1{#/blank#}(they) trips. I also once hitched a ride when I was traveling in America.

    I{#blank#}2{#/blank#}(drive) on the road when my car stopped. I was going to a town which was farther than I had expected. My tank(油箱) became empty{#blank#}3{#/blank#}I got there. Standing there, I didn't know what to do. I just knew that I needed help. But I could see nobody around. Who could I turn{#blank#}4{#/blank#}? Then I thought of scenes that I had seen in Hollywood{#blank#}5{#/blank#}(movie). I remembered that people in America loved hitching a ride. I told I myself that I could do that, too.

    So when a car was coming. I tried to hitch a ride. To my joy, the car really stopped in front of me. The driver was{#blank#}6{#/blank#}old man. After{#blank#}7{#/blank#}(know) my problem, he said he could help me out. He took me to the{#blank#}8{#/blank#}(near) gas station. But then he left as he had something important to do.

The only possessions {#blank#}6{#/blank#} could be seen were one broom, a few tin plates and cups and a couple of jars. They didn't speak much of the local English dialect. When {#blank#}7{#/blank#} (sit) around, she loved listening to them softly talking to each other in their language{#blank#}8{#/blank#} (occupy) with teaching, she had no time for social{#blank#}9{#/blank#} (activity). Instead, she often joined in their family party. She felt it was {#blank#}10{#/blank#} privilege to spend a day with them.
