题目内容
3．Jake asked me whereto buy （buy） the book．分析 Jake问我在哪里买的这本书．
解答 答案：to buy
通过观察句子结构及句意可知为"问某人某事"根据句中的关键词ask结合空格前的疑问词where以及所给动词buy，可知ask后接"sb+疑问词+不定式"构成的双宾语，其中sb即me作间接宾语，疑问词+不定式即where to buy 意为"在哪里买"作句中的直接宾语，故答案为to buy
点评 本题考查完成句子．首先通过观察句子结构，结合句意确定改词在句子中成分，根据所给词作出正确的转换．在本题中考查ask后接"sb+疑问词+不定式"构成的双宾语注意类似的词还有，advise，show，teach，tell等，例如He will advise you what to do．他会建议你们做什么．
