Trouve sat up on its back legs arid growled（吼叫）the words “How are you, Grandmama?” The audience roared with laughter and clapped. Twenty-year-old Aleck gave the dog a morsel（一口）of food. His hard wok paid off. His dog could talk!
Aleck was fascinated with the different sounds of people’s speech. His father taught students who had a speech problem to improve their speech. Aleck paid close attention. Could an animal form sounds into words, too? He decided to experiment with Trouve, the family dog.
The easy part was teaching Trouve to growl whenever Aleck wanted. The little dog growled for a morsel of food.
Next Aleck moved the dog’s “lips’ as it growled. It sounded like “ma ma ma.” Trouve learned quickly to stop the growling just as Aleck’s hand moved away. They practiced and practiced until the dog said “ma ma” perfectly.
Soon Aleck discovered more. If he pushed gently under the dog’s jawbone（下颚骨）, it made the “ga” sound. If he pushed once and moved the dog’s lips twice, he could make the dog say, “ga ma ma”. With even more practice, it sounded like “grandmama.” Whenever Trouve said “grandmam,” Aleck gave the god two treats, so Trouve loved the lessons.
Aleck tried to teach his dog to move its tongue. So that Trouve could say more words. That didn’t work, but Aleck didn’t give up.
After many hours of practice, Trouve could say, “Ow ah oo ga-ma-ma?” This sounded just like “How are you, Grandmama?”
Friends and neighbors traveled to see young Aleck and his amazing talking dog. Rumors spread that the dog could speak by itself, which wasn’t true. No matter how much Aleck tried, the dog was never able to move its lips without help.
Aleck’s full name was Alexander Graham Bell. He wanted to know more about the world all his life. He had many ideas. Some worked; others didn’t. But he kept trying—always learning; One of his inventions was something called the telephone.
