"No field of study can advance significantly unless outsiders bring their knowledge and experience to that field of study."
I strongly agree with the assertion that significant advances in knowledge require expertise from various fields. The world around us presents a seamless web of physical and anthropogenic forces, which interact in ways that can be understood only in the context of a variety of disciplines. Two examples that aptly illustrate this point involve the fields of cultural anthropology and astronomy.

Consider how a cultural anthropologist's knowledge about an ancient civilization is enhanced not only by the expertise of the archeologist——who unearths the evidence——but ultimately by the expertise of biochemists,geologists, linguists, and even astronomers. By analyzing the hair, nails, blood and bones of mummified bodies, biochemists and forensic scientists can determine the life expectancy, general well-being, and common causes of death of the population. These experts can also ensure the proper preservation of evidence found at the archeological site. A geologist can help identify the source and age of the materials used for tools, weapons, and structures——thereby enabling the anthropologist to extrapolate about the civilization's economy, trades and work habits, life styles, extent of travel and mobility, and so forth. Linguists are needed to interpret hieroglyphics and extrapolate from found fragments of writings. And an astronomer can help explain the layout of an ancient city as well as the design, structure and position of monuments, tombs, and temples——since ancients often looked to the stars for guidance in building cities and structures.
这篇文章的精彩之处莫过于层出的复扎句和排山倒海似的并列句和排比句了。大家千万别给这个作者对于 anthropology &astronomy的高深见解吓倒，我觉得他肯定是考古或天文专业的。因此，我们也可仿效一下，举些符合自己熟悉的专业背景的知识，因为BT的ets们就喜欢这种味儿。
