| In an attempt to produce premium oysters, a firm in Scotland has developed a prototype of a submersible oyster farm, sitting below the surface of the ocean, and it provides ideal conditions for the mollusks' growth. A. farm, sitting below the surface of the ocean, and it provides B. farm, sitting below the surface of the ocean for providing C. farm that sits below the surface of the ocean and providing D. farm that sits below the surface of the ocean and provides E. farm that is sitting below the surface of the ocean and it provides 答案是D，做是做对了。 但是我觉得，provides前面应该有个that，不应该被省略 所以我差点因为这个排除了D选项，就是看了前后几个错误更明显才选这个的。 基于什么理由这里的that可以省略呢？我的理解中gamt里面，并列结构的定语从句的that都不能省略。 |
