以下是引用seasnow在2006-1-20 14:33:00的发言:56. 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 选C? 如果该句中的protecting改为protect是不是A就正确了? |
