老托福语法原题，请大家帮忙解答，谢谢

1.The archaeologist [attempts] to reconstruct [the past] by analyzing, dating, and comparisons systematically [excavated] sites and artifacts.
2.Over the [entirely] surface of Earth,[there] is not a cubic inch of air [nor] an ounce of soil in [which] water is not present.
3.The planet Venus [is comparing] with Earth [in terms of] size, mass, and density, but [has] a thick carbon dioxide atmosphere, a slow roation, and [no moon].
并解释一下为什么错误，怎么改正，谢谢！

Answer 1

1 excavated--to excavate
这里应该是用不定式作状语。
2 entirely-entire
这里surface是名词，应该用形容词修饰名词，所以改成entire "整个的".
3 is comparing-is compared
这里主语The planet Venus与地球相比较，是被动关系。
