A sign is another kind of language.Here are some of them that you see on the roads.Number one is a sign with the number thirty on it.When drivers see this sign,they must not go at more than thirty kilometres an hour.We see this sign when we are getting near a town.Number two is a sign that we're near a crossing.We must drive carefully.Number three is a sign that there is a bend in the road.Again,we must drive slowly and carefully.It is not safe to go round a bend very fast.Number four is a sign that there is another road coming in from the right.There is a junction at this place.Number five is a sign that there is a hill and number six is a sign that the road gets narrow.Drivers must go slowly and carefully.Number seven has the word "SCHOOL" on it.This is a sign that there is a school at the side of the street or the road.Perhaps there are children going to or leaving school.So drivers must look carefully and go slowly.
