问题描述：
he was sitting in a chair reading when we went into his study分析句子成分
答
he(主语） was sitting （谓语）in a chair（状语） reading（状语,表伴随状态） when we went into his study（时间状语）reading是不是分词结构是的reading为什么不是真正的动词，我认为sitting in a chair 做方式状语不对 was sitting 是进行时态的位于，reading是伴随状语，表示他坐在椅子上的伴随动作。他正坐在椅子上读书。进行时态的谓语是不是紧跟在其后
