9、D. when was it that; that参考答案：B【详解】考查强调句作宾语从句和定语从句。强调句的特殊疑问句的结构是：疑问词+is/was it +that/who，在第一句话中强调句的特殊问句是做宾语从句，语序变成陈述句，it在was前面，根据句意：-你知道他们什么时候认识的吗？-就是在他们在苏格兰教汉语的去年认识的。可知第二空是定语从句，不是强调句，先行词是last year，定语从句缺少时间状语。选B。【点睛】做这类题目要考虑全面，不仅要看出是强调句还是定语从句，也要注意这是宾语从句，语序的问题也要弄清，要求能力很高。25.- Did you see a man in bla
