英语单选
was it six old years when he came to China for the first time ___ he bagan to learn Chinese. A. where B. how C. which D. that 请分析，谢谢
选A:where 考点：定语从句 定语从句___ he began to learn Chinese中，句子基本结构完整，所以不选C，D how不是定语从句的关联词 所以选A 本句考点不是强调句。it is ... when结构是很正常的。 全句如果调整语序就是When he came to China where he began to learn Chines for the first time was six years old. 用it代替when...time主语从句。 如果视为强调句，将it is ... that结构去掉，就是He began to learn Chinese six years old when he came to China for the first time. 这句话是病句。所以不能视为强调句。
