问题 If the photocopier does not work at all, please check to see if it is plugged in ______and the power switch is turned to "ON."
选项 A、correct
B、correction
C、correcting
D、correctly
答案 D
解析 空格在完整的句子结构的被动语态结构it is plugged in后面，空格处要填适合完整的句子的修饰词。plugged in作为一个整体用作动词，该及物动词用于be plugged in的被动语态形态。空格处是副词的置。in不是介词，plug in作为一个整体使用。因此空格处要填correctly。
