Employing the same techniques for genetically enhancing plants that make them Answer: c 请问B选项错在何处?我觉得with的用法做“拥有”讲应该没有什么问题。大家指点
so that 从句在这里表结果,如果前面用了with的独立结构,就无法表达是什么导致so that后面的结果了。因为独立结构和主句平行,表明主语的状态,使得so that的结果变成无因之果,逻辑上没有依靠。并且前面加了逗号,they的指代有歧义,因为with独立于they之外的结构使得techniques,plants和they的关系变得平等起来,指代就不明了。
