4.【2020 •铁岭葫芦岛】—Could you tell me ________ the book?
—Sure, I bought it online.
A. why you bought B. when you bought C. where you bought D. how much you paid for
【答案】C
【解析】句意：——你能告诉我你在哪里买的书吗？——当然，我在网上买的。考查宾语从句。why you bought你为什么买；when you bought你什么时候买的；where you bought你在哪买的；how much you paid for你付了多少钱。根据答语I bought it online可知，我在网上买的，故可推知问句是询问“在哪买的书”，故应用where引导宾语从句。故选C。
