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.
The Romans neglected pure theories because______.
选项 A、they were fond of constructions
B、they were busy invading other countries
C、they spend their time inventing computing machines
D、they accomplished practical wonders
答案B
解析 参阅第四段第二句。第四段谈到罗马人忽视纯理论的原因，第一个原因就是他们花了太多时间征服周边国家，二是无暇顾及抽象理论的研究。B正符合此意。
