问题补充：

When he came to, he found himself a chair, with his handsback..

A. to sit; tied

B. sitting; tying

C. sat; tied

D. sitting; tied

答案：

A. to sit; tied

B. sitting; tying

C. sat; tied

(答案→)D. sitting; tied

解析：考查宾语补足语。第一空himself与sit构成主动关系，使用现在分词的形式。第二空的hands与tie（捆，系）构成被动关系，故使用过去分词。句意：当他苏醒过来的时候，分析自己做在椅子上，手被捆在后面。故D正确。
