问题补充:
Thanks for your help , I couldn’t finish the work in time .
A. with which
B. under which
C. without which
D. for which
答案:
A. with which
B. under which
(答案→)C. without which
D. for which
解析:考查定语从句中关系代词前面的介词。定语从句中关系代词前面的介词有三种来源:先行词的搭配;定语从句中词汇到的搭配;句子上下文的意思;本句是根据上下文的意思判读使用without。句意:谢谢你的帮助,要是没有你的帮助,我就不能及时完成工作。Which知道help作为without的宾语。故C正确。
