B、has not been finished
C、did not finish
D、not having been finished

网考网参考答案：D
网考网解析：
[解析] our work not having been finished我们的工作尚未完成，为分词独立结构作状语，表示原因。注意：否定的分词短语中的否定词not必须放在整个分词短语的最前面而不能放在其后，如只能说not having been finished，而不能说having not been finished。 document.getElementById("warp").style.display="none"; document.getElementById("content").style.display="block"; 查看试题解析出处>>
