In a plan to stop the erosion of East Coast beaches, the Army Corps of Engineers proposed building
parallel to shore a breakwater of rocks that would rise six feet above the waterline and act as a buffer,
so that it absorbs the energy of crashing waves and protecting the beaches.
(A) act as a buffer, so that it absorbs
(B) act like a buffer so as to absorb
(C) act as a buffer, absorbing
(D) acting as a buffer, absorbing (E) acting like a buffer, absorb 对于正确答案C我没有意见。 我想问的是,absorbing...and protecting....是分词做伴随状语结构, 分词做伴随状语结构的逻辑主语应该是主句的逻辑主语,(语法书说的) 也就是the Army Corps of Engineers 。 但这个是不对的,因为根据意思absorbing...and protecting....的主语应该是 a breakwater of rocks . 关于这个我应该怎么理解呢?? 中秋的困惑~~
