Every Dog I-Ias Its Say
Kimiko Fukuda， a Japanese girl， always wondered what her dog was trying to say. Whenever she put on makeup， it would pull at her sleeve. 46_______ When the dog barks， she glances at a small electronic gadget（装置 ）. The following "human" translation appears on its screen: "Please take me with you. " "I realized that"s how he was feeling." said Fukuda. The gadget is called Bowlingual，and it translates dog barks into feelings. People laughed when the Japanese toymaker Takara Company made the world"s first dog-human translation machine in 2002. But 300，000 Japanese dog owners bought it. 47_______
"Nobody else had thought about it，" said Masahiko Kajita， who works for Takara. "We spend so much time training dogs to understand our orders; what would it be like if we could understand dogs？"
Bowlingual has two parts. 48_______ The translation is done in the gadget using a database （资料库） containing every kind of bark.
Based on animal behaviour research， these noises are divided into six categories: happiness，sadness， frustration， anger， declaration and desire. 49_______ In this way， the database scientifically matches a bark to an emotion， which is then translated into one of 200 phrases.
When a visitor went to Fukuda"s house recently， the dog barked a loud"bow WOW". This translated as "Don"t come this way". 50_______
