Question

【题目】Kitty asked her cousin how long .

A. he had come to Beijing B. had he come to Beijing

C. he had been in Beijing D. had he been in Beijing

Answer 1

【答案】C

【解析】句意：基蒂问她的表妹他在北京呆了多久。宾语从句需用陈述语序，排除B和D；how long多久，多长时间，询问做某事做了多长时间，后面的动词需用延续性动词，come to是终止性动词，be in +地点：在某地，表示一种状态，是延续性动词，故选C。
