One morning, I was waiting at the bus stop, worried about {#blank#}1{#/blank#} (be) late for school. There were many people waiting at the bus stop, {#blank#}2{#/blank#} some of them looked very anxious and {#blank#}3{#/blank#} (disappoint).When the bus finally came, we all hurried on board.

I heard a passenger behind me shouting to the driver, but he refused {#blank#}6{#/blank#} (stop) until we reached the next stop. Still, the boy kept {#blank#}7{#/blank#} (ride). He was carrying something over his shoulder and shouting. Finally, when we came to the next stop, the boy ran up to the door of the bus. I heard an excited conversation. Then the driver stood up and asked, “Did anyone lose a suitcase at the last stop?” A woman on the bus shouted, “Oh, dear! It's {#blank#}8{#/blank#} (I).”She pushed her way to the driver and took the suitcase thankfully. Everyone on the bus began talking about {#blank#}9{#/blank#} the boy had done, and the crowd of strangers {#blank#}10{#/blank#} (sudden) became friendly to one another.

    {#blank#}5{#/blank#} picking the tea, he received the news of his mother s illness, so he  {#blank#}6{#/blank#} (careless) put the leaves in his right sleeve and left Hangzhou for Beijing. He visited his mother immediately upon his  {#blank#}7{#/blank#} (arrive) in Beijing, and Empress Dowager smelt the fragrance of the leaves in his sleeve and wanted to have a taste. Emperor Qianlong ordered some tea for Empress Dowager, and she found  {#blank#}8{#/blank#} (she) completely refreshed after  {#blank#}9{#/blank#} (drink) a cup of tea, and she even praised it as a treatment for all ills.
