梅森和狄克逊因为发现一条分界线而出名；正确测绘金星凌日图的人不是阵容强大的跨国科学家团队，而是无名船长詹姆斯库克（其实人家的名气也不小啊）~~~

因为原著为美国人所写,单词采用美式拼法,不抄全文,然后听写单词或词组(用[-No-]表示)以及句子(用[---No---]表示)。请边听写边理解文意，根据上下文注意各句标号，这样有助于提高正确率。

Soon afterward, Maskelyne returned to England where he became astronomer royal, and Mason and Dixon — now evidently more seasoned — [-1-] for four long and often perilous years surveying their way through 244 miles of dangerous American [-2-] to settle a boundary dispute between the estates of William Penn and Lord Baltimore and their respective colonies of Pennsylvania and Maryland.

Back in Europe, Maskelyne and his counterparts in Germany and France were forced to the conclusion that the transit measurements of 1761 were essentially a failure. One of the problems, [-6-] , was that there were too many observations, which when brought together often proved contradictory and impossible to resolve. The successful charting of a Venusian transit fell instead to a little-known Yorkshire-born sea captain named James Cook, who watched the 1769 transit from a sunny hilltop in Tahiti, and then went on to chart and claim Australia for the British crown.

The precise distance, we now know, is 149.597870691 million kilometers.) [---8---]

The result was the famous Mason and Dixon line, which later took on symbolic importance as the dividing line between the slave and free states.

Upon his return there was now enough information for the French astronomer Joseph Lalande to calculate that the mean distance from the Earth to the Sun was a little over 150 million kilometers.
The Earth at last had a position in space.
此后不久，马斯基林回到英国，成为皇家天文学家，而梅森和狄克逊--这时候显然更加成熟--启程前往美洲，度过漫长而时常是险象环生的4年。他们穿越393公里危险的荒原，一路上搞测量工作，以解决威廉•佩恩和巴尔的摩勋爵两人地产之间的以及他们各自殖民地--宾夕法尼亚和马里兰--之间的边界纠纷。结果就是那条著名的梅森-狄克逊线。后来，这条线象征性地被看做是美国奴隶州和自由州之间的分界线。（这条线是他们的主要任务，但他们还进行了几次天文观测。其中有一次，他们对1度经线的长度作了当时那个世纪最精确的测量。由于这项成就，他们在英国赢得了比解决两位被宠坏了的贵族之间的边界纠纷高得多的赞扬。）
回到欧洲以后，马斯基林与他的德国和法国同行不得不下结论，1761年的凌日观测工作基本失败。具有讽刺意味的是，问题之一在于观测的次数太多。把观测结果放在一起，往往证明互相矛盾，无法统一。成功绘制金星凌日图的却是一位不知名的约克郡出生的船长，名叫詹姆斯•库克。他在塔希提岛一个阳光普照的山顶上观看了1769年的凌日现象，接着又绘制了澳大利亚的地图，宣布它为英国皇家殖民地。他一回到国内，就听说法国天文学家约瑟夫•拉朗德已经计算出，地球到太阳的平均距离略略超过1.5亿公里。（19世纪又发生两次凌日现象，天文学由此得出的距离是1.4959亿公里，这个数字一直保持到现在。我们现在知道，确切的距离应该是1.495 978 706 91亿公里。）地球在太空中终于有了个方位。
