你对这个句子的断句有些问题,应该是:
the Army Corps of Engineers proposed building parallel to shore a breakwater of rocks that ____________ 换句话说,
parallel to shore是状语表示"where"
A proposed building a breakwater of rocks that ____.
Question: where would the breakwater of rocks be built?
Answer: Parallel to shore.
至于v-ing,你版面搜索"v-ing"吧,已经讨论得很详尽了
