One day，an old woman walked into a clothes shop.She asked the salesgirl to let her have a look at a new dress on display（展览），but the girl stood still behind the counter，taking no notice of the request.
The old woman spoke to the girl again，raising her voice a bit but still received no answer.The old womanpeered（仔细看）at the girl and nodded to herself.“I am too old to see well.I can't even tell a plastic model from a real girl."
At this，the girl shouted at the old woman."What？Did you call me a plastic model？"
The old woman was greatly surprised."Oh，dear me，"she cried.
"The model can speak，it must be a robot（机器人）of a new type which has been made recently."
