回LS的问题,我觉得 C 和 D 还是有区别的,此前我还以为 such as 的举例是否一定需要用逗号隔开,用为此我还查了大全。 但发现大全里两种用法都有,而且对于主语举例的,可以直接加谓语,不用逗号分隔(OG 619)。可见加逗号与否不应该作为判断的主要依据。 C 和 D 的表达实际意思是不同的,在我看来,C、D中 such as 举例说明的对象不一样 C. The market for (recycled commodities such as aluminum and other metals) remains such as 是对 recycled commodities 的举例 D. The (market for recycled commodities), such as aluminum and other metals, remain 由于逗号的分隔,我认为 such as 更加应看成是对 market 的举例,所以D不合逻辑,即便将 remain 改成 remains 也不可选 |
