A sign is another kind of language. Here are some of them that you see on the

roads.

  Number One is a sign with a number on it. When drivers see this sign with

thirty on it, they must not go at more than thirty kilometers 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 (拐弯) in the road. Again, we must

drive slowly. It is not safe to go around a bend very fast.

  Number Four is a sign that there is another road coming in from the right.

There is a junction (交叉) 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 devote his attention to the drive and go slowly.

  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.

  Number Eight is a sign with the letter "P" on it. The letter "P" means
