This fact has been so universally acknowledged by previous writers on the subject that it seems hardly necessary to quote individual opinions.

[单项选择]Passage Three

Thousands of years ago man used handy rocks for his surgical operations. Later he used sharp bone or horn, metal knives and, more recently, rubber and plastic.

The tool is the laser and it is, being used by more and more surgeons all over the world, for a very large number of different complaints. The word laser means: Light Amplification by Stimulated Emission of Radiation. As we all know, light is hot; any source of light--from the sun itself down to a humble match burning--will give warmth. But light is usually spread out over a wide area. The l

[单项选择]Thousands of years ago, royalty of diverse cultures were often buried in extremely lavish tombs that they themselves commissioned in preparation for their inevitable deaths. About 2,200 years ago, a Chinese emperor named Qin Shihuang had such a tomb prepared. At the age of thirteen, Qin Shihuang had succeeded his father as emperor. The boy was very aggressive and ambitious. He assumed full power at the age of 22 by ridding himself of his rival, a man who had controlled the throne while Qin Shihuang was a minor. Qin Shihuang’s goal was to unify and subjugate all of the Chinese states using his powerful political, economic, and military strength. Despite an ongoing quest for immortality, Qin Shihuang died while traveling at the age of 49. Although he has been dead for centuries, historians can continue to learn of his life by studying the artifacts found in the extravagant tomb in which he was laid to rest.

For the pure joy of learning, scholars ventured into distant kingdoms and observed their customs. They tasted the foods; they questioned the wise men about their gods and their history; they sat in fearful admiration on the banks of newly discovered rivers. Then they went back home reflecting upon what they had seen, and perhaps they wrote a book or two about their discoveries. Slowly, nations learned about each other, men met and ideas spread--for better or worse.
There was a time, close to ours, when artists and writers traveled all over Europe and sometimes further to study ancient works of art and to exchange ideas and methods with their foreign colleagues. Poor adventurers traveled on foot whil
