33.Each Indian tribe (部落) had a different language.Many Indians never learned any language except their own.Do you know how Indians from different tribes talked to each other?They had two ways to talk without sound.One way was by sign language; and another way was by signals.Sign language is a way of talking by using signs.Indians used sign language when they met strangers.In this way,they could find out whether the stranger was a friend or an enemy.In Indian sign language,sings were made with the hands.One sign meant "man".Another meant "horse".To tell the time of the day when something happened,an Indian pointed to the sky.He showed where the sun had been at the time.
Indians usually used signals when they wanted to send messages to someone far away.To make signals,an Indian might use a horse.He might use a blanket.Or he might use smoke,a mirror or fire arrows.
To signal that he had seen many animals,an Indian rode his horse in a large circle.Sometimes the Indians gave a signal like this and then went away to hide.This meant that there was danger.
The blanket signal was visible from far away.An Indian began to wave the blanket from side to side in front of him.An Indian could send many different signals with his blanket.
He could also send many signals with a mirror.He usually used the mirror to warn someone of danger.Or he tried to get the attention of a person far away.But he also used it to send message in code (密码).Of course,mirrors could be used only when the sun was shining.At night,Indians used fire arrows for signaling.
An Indian also sent signals with smoke.He made a small fire of dry wood.Then he put grass or green branches on it.He held a blanket over the tire for a minute.When he removed the blanket from the fire,there was a cloud of smoke.The number of clouds of smoke told his message in code.
Now you can see that Indians did not need to learn each other’s languages.They could talk to one another by using signals or sign language.
An Indian used a mirror to __.
a、 draw the attention of someone in the distance
b、send his message in code
c、 warn someone of danger
d、all of the above
