听力原文： One of the important materials used in the construction of buildings and roads is cement. It is a powder made mainly from limestone and clay. Even though the ancient Egyptians and Romans used a kind of cement, it was not until 1824 that an English bricklayer developed cement strong enough for modern roads and buildings.
While the bricklayer was experimenting in his kitchen, he found that a mixture of limestone and clay that had been heated formed a substance. This substance became hard and stone-like as it cooled. When it was grounded into a fine powder, it could be stored.
When the powder was mixed with water, it made an excellent quality of cement that quickly hardened in sunlight or even under water, it made an excellent quality of cement that is used today.

These are some of the signs that you see on the roads of Great Britain.
Number one is a sign with the number thirty on it. When drivers see this sign they must net go at more than thirty miles an hour. We see this sign when we get to parts of the country where there are many houses and other buildings, for example, when we are getting near a town. Thirty miles an hour is the speed limit.
Number two is the sign for the end of the speed limit. We are out of the town now and may go at more than thirty miles an hour.
Number three is a sign that we are near a crossroad, that is, a place where two reads cross. We must drive carefully.
Number four is a sign that there is a bend in the road. Again, we must drive slowly and carefully.
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 file side of the street or road. Perhaps there are children going to school or leaving school. So drivers must look carefully and go slowly until they are past the school building.
Number eight is a sign with the letter P on it. The letter P is for" Parking". A parking place is a place where drivers may leave their cars. If the driver of a car wants to leave his car and go to shops, he looks for the sign. Then he knows that he may leave his car there.
Who will most probably read the passage？
A．People who drive badly.
B．People who are learning to drive.
C．People who drive well.
D．People who drive carelessly.
