37. The Louisiana Purchase of 1803 increased the territory of the United States by approximate 846,000 square miles, practically doubling the area of the United States. 答案：B. approximate: approximately

分析：approximately 副词修饰句子

参考译文：1803年的Louisiana购买使得美国的疆土扩大了846,000平方英里， 基本上是翻倍。

我选的是C,难道不应该是过去时吗?

approximate是修饰面积还是修饰INCREASED嘞??

注里的:approximately 副词修饰句子,是指修饰哪个句子?
