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 kilometers can 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. Number eight is a sign with the letter “ P ” on it. The letter “ P ” means “ Parking ”. At some places, there're the signs “ No parking ” or “ No waiting”. If a driver leaves his car near one of these signs, a policeman may come and write down the number of his car. 小题1:At the places where you see Sign 1, .
