We've been together. What do you say in sign language?

This is a detailed picture demonstration, I hope you can understand it.

Explain it according to the classmates downstairs.

Sign language (C) refers to a certain meaning or word formed by comparing gestures and simulating images or syllables according to the changes of gestures.

It is a sign language for people with hearing impairment and unable to speak (that is, deaf people) to communicate and exchange ideas with each other.

It is "an important auxiliary tool for oral English" and the main communication tool for hearing-impaired people.

The difference between sign language and language mainly lies in pronunciation and whether deaf people think with gestures.

On July 2065438+2008 1 day, China implemented the National Glossary of Sign Language and the National Braille Program, which were published as language norms.

Sign language has existed since ancient times, and it is not just a patent for deaf people. The ancients used sign language to communicate their opinions, and then slowly produced language.

The ancients mainly hunted and cultivated, and there were few rules to follow in society, so the deaf-mute people were more able to adapt to life.

However, with the development of culture and the progress of society, many abstract symbols have appeared. In order to adapt to social life, we have to express our feelings in sign language.
