托?？荚嚨穆犃Σ糠謱υS多考生來說都是一大挑戰(zhàn),，尤其是理科類的內容,。為了幫助大家提升聽力能力,，小編特意整理了一段關于天文學的精彩內容,。這不僅能幫助你了解天文學的基本知識,，還能在托福聽力中取得更好的成績。接下來,，讓我們一起深入這段聽力材料吧,。

托福聽力黃金段子：天文學

In ancient civilizations, many believed that the earth was flat. However, over 2,000 years ago, ancient Greek thinkers presented two compelling arguments to refute this idea, both rooted in their observations of celestial bodies. First, they noted that during lunar eclipses, when the earth is positioned between the sun and the moon, the shadow cast on the moon is always circular. This observation led them to conclude that the earth must be spherical; if it were a flat disc, the shadow would appear elongated rather than round.

The second argument stemmed from their travels. The Greeks observed that as they journeyed southward, the North Star, or Polaris, seemed to descend in the sky. Conversely, in more northern regions, it appeared higher. This discrepancy in the North Star's position allowed the Greeks to estimate the earth's circumference. Ancient records suggest a figure of 400,000 stadiums (the plural of stadium). Although the exact length of a stadium is uncertain today, it's often approximated to be around 200 meters—the size of many sports fields. Thus, the Greeks' estimate would equate to roughly twice the modern accepted measurement, showcasing their remarkable accuracy for a time long before the invention of the telescope.

通過這樣的段子，考生們可以積累有趣的科學知識,，同時提升自己的聽力技能,。希望以上內容能為你的托福備考提供幫助，祝愿大家在考試中取得優(yōu)異成績,！
