考题讲解

题目分析:
略。

选项分析:

A选项:“坐落在海平面以下”和“提供了理想的生长环境”均是a submersible oyster farm干的事情,两者应保证平行并列。

B选项:介词短语for providing ideal conditions for the mollusks' growth变为了修饰sit事件的状语,这在逻辑关系上有误。“坐落在海平面以下”和“提供了理想的生长环境”应为农场能干的两个并列的事件,两者之间没有修饰关系。

C选项:并列连词and连接的 that sits below the surface of the ocean和providing ideal conditions for the mollusks' growth不具备平行关系。

D选项:Correct. 本选项在语法和逻辑上均是正确的。

E选项:并列连词and身后的句子是完整句,无法和身前的定语从句平行(若同是定语从句,必然需要缺少一个成分)。
