koko in inglese:

When we told Koko the news, she was silent for about ten minutes.

Newspapers and television stations around the world told the story of Koko and her kitten.

Koko is a female gorilla.

Researchers at the Gorilla Foundation have to spell out words like "c-a-n-d-y" and "g-u-m" when Koko is nearby.

Koko knows and uses more than 500 words in sign language, the language of deaf people.

For example, Koko was asked to choose a house or a tree for shelter from the rain.

Dr. Patterson: Not at all! Koko has taught us that gorillas are intelligent enough to learn sign language.

Koko chose the tree.

Dr. Patterson also uses spoken language with Koko.

When you want to say "I promise", if you say "koko ni chikaimasu" you'll sound more like a native.

After only 36 months, Koko could use 184 signs.

A reporter is interviewing Dr. Patterson about Koko, a talking gorilla.

They wanted to give Koko a new pet.

Koko herself cannot use spoken language, but she loves to listen to people's conversations.

Because of this, Koko can understand hundreds of spoken words.
