    Mr. Smith lived in the country, but he worked in an office in a big city. So he went to work {#blank#}1{#/blank#} train every morning and came home in the same way.

    One morning he was {#blank#}2{#/blank#} his newspaper silently on the train when {#blank#}3{#/blank#}man sitting behind him, who Mr. Smith had never met before, leaned (倾斜) forward, tapped (拍打) him on the shoulder and spoke to {#blank#}4{#/blank#}. The man said," You're leading a very interesting life. You get on the same {#blank#}5{#/blank#}at the station at the same time every morning, and you always sit in the same seat and read the same newspaper. Life is always the {#blank#}6{#/blank#} to you.

    Mr. Smith put his paper {#blank#}7{#/blank#}, turned around, and said to the man, "Who are you? {#blank#}8{#/blank#} do you know all these things about me?"

    "{#blank#}9{#/blank#} I'm always sitting in this seat behind you," the man answered." This morning, I thought it would be good to {#blank#}10{#/blank#} hello."
