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
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

[简答题]Ever since the ancient Romans imposed their language on neighboring barbarians, the teaching of Latin has been inseparable from cultural politics. In the Middle Ages, Latin was the preserve of the Church, whose leaders believed that the language was inherently holier than the vernacular, and who used Latin as a means of establishing a distance between priests and their parishioners. In the Renaissance, the classics were seen as a beneficial source of eternal, universal truths — "From Cicero I’ve learned to be myself," an Italian humanist announced —and such a belief persisted well into the nineteenth century. The argument for the improving qualities of Latin is still made by the American Classical League, which points to studies showing that schoolchildren who have studied Latin achieve higher standardized test scores than their non-Latinist peers.

[单项选择]Learn about Light 1 Ancient civilizations were amazed by the existence of light for thousands of years. The Greek philosophers believed that light was made up of countless, tiny particles that enter the human eye and create what we call vision. However, Empedocles and a Dutch scientist named Christian Huygens believed that light was like a wave. According to them, light spread out and travelled like a straight line. This theory was accepted during the 19th century. 2 ln 1905, Albert Einstein published a research paper in which he explained what is referred to as the photoelectric effect. This theory explains that particles make up light. The particles Einstein was referring to are weightless bundles（束）of electromagnetic（电磁）energy called photons（光子）. Today, scientists agree that light has a dual（二重） nature — it is part particle and part wave. It is a form of energy that allows us to see things around us. 3 Things that give off light are known as sources of light. During the
