问题     In general, the ancient Romans were a practical people. They cared less about philosophy anti pure mathematics than did the Greeks. The Romans were the best of the ancient engineers anti architects. They were brilliant students of Greek geometry and trigonometry, and they applied their knowledge to the constructions of fine bridges, roads, aqueducts, and public buildings.
    They knew about the smelting of iron ore, but they used the iron they produced mainly for spears, swords, and shields, rather than for building construction.
   While the Romans accomplished practical wonders, they did very little theoretical scientific thinking. Because of their frequent wars, many of their inventions were no more than improvements in the design of Greek weapons with which they were familiar.
    There are two reasons for the Romans neglect of philosophy and pure mathematics. First, they were apparently too busy conquering nearby nations and forming them into a rapidly growing empire to waste much time on abstract thinking. Secondly, they were handicapped by the rigidity of their numerical system. The Romans did all of their arithmetic on an abacus, the ancient counterpart of the modem computing machine. Their number system discouraged the study of pure mathematics.
By saying that the ancient Romans were "practical", the writer means ______.
选项 A、they could use their knowledge in their constructions
B、they learned geometry and trigonometry very well
C、they paid no attention to philosophy and pure mathematics
D、they could became engineers and architects
答案A
解析 本题答案参阅第一段，practical表示讲求实际，古罗马人的讲求实际体现在他们能把所学的代数、几何学知识运用于工程和建筑领域，所以本题选A。
