考查非谓语动词。句意：(因为)那些书是一周多之前订的

【题目】_______ over a week ago, the books are expected to arrive any time now.

A. Ordering    B. Having ordered

C. Ordered    D. To order

【答案】C

【解析】

考查非谓语动词。句意：(因为)那些书是一周多之前订的，现在随时有可能送到。books和order是动宾关系，即order books/books are ordered，故用过去分词表示被动和完成，在此相当于原因状语从句becau they were ordered...。故选C。
