<p>答案:↓↓↓<p class="nav-title mt10" style="border-top:1px solid #ccc;padding-top: 10px;">孙卫的回答:<div class="content-b">网友采纳  ----(Have)you(finished)yourhomework?----Yes.I(finished)itanhourago.  你完成作业了吗?是的,我一小时前写完了.  第一句是现在完成时态,由助动词have加上过去分词finished构成,表示到目前为止已经做完了.答句有时间状语anhourago,是表示过去的,所以动词finish要用过去式.  因此选择C项正确.
