I didn't know you lived a hard life until I __(read) your ar

I didn't know you lived a hard life until I __(read) your ar 为什么是Since I know what a hard life she lived而不是Since I know w 英语语法问题I didn't know you were her mother和I didn't know you ar 同义句1.I didn't know anything until he told me.I knew______ __ i didn't know you __(be ) here I didn't know where he lived还是I didn't know where he lives对? I didn't know how import you are until left me. I didn't know him until you had told me .有个小问题. I didn't know the matter until you told me转化为强调句 i didn't know about it until he told me . “I know you study hard .But why didn't you pass the exam?” M The days are gone when I lived a hard life
