I was wondering through the street when I caught sight of a strange store; there wasn't anything but empty shelves at one end of the room in front of which a man was standing on a【21】platform(平台) and shouting loudly that the greatest sale of the year was【22】to begin. I decided to stay and see【23】would happen. A salesman began to pile【24】of things on the shelves such as table-lamps, clocks, combs and a large quantity of small packets【25】in bright paper. When the man at the table was【26】that a large crowd of peo pie had gathered, he began handing out the packets, asking for the sum(金额) of three pence【27】, and declaring the【28】of the contents was fifty times as much.
I paid three pence for my packet and was【29】told I should not open it until after the sale. All these beautiful things the man announced, would be simply【30】. He was as good as his【31】, for he held up a razor(剃刀) and asked a young man if it was【32】six pence. The young man was【33】the matter and was at once handed the razor for the sum asked.【34】happened with a number of other small articles.
Then【35】asking small sum like six pence, the man began to【36】large amounts (数量)for "very rare, high-quality" objects. The people【37】, thinking that these too were being "given away", soon found themselves【38】a great deal for useless things. I decided I'd better go quickly before being【39】into buying something I didn't want. I went into the street and opened my prize-packet, only to find that I had been【40】with a cheap bottle of scent(香水) !
