I have a sister she is eight=I have_________sister

I have a sister she is eight=I have_________sister I have a sister who works in Beijing.= I have a sister.She works in Beijing.这里的she可不可以用the sister代替啊? i donts have a sister还是i dont have sister i have a sister that she is leixiang.这句话对吗?怎么改我不太会 I have a sister ,too,but she is in the photo.这里用is i wish i ( ) a sister (have) ? I have a sister 改写I have a sister 中对 a sister 进行提问 I have a sister.She works in Beijing.I have a sister who works in Beijing,这里的定语从句中who指代的是什么 是a sister还是she I have a sister.She works in Beijing.I have a sister who works in Beijing,这里的who是指代a sister 那为什么改为简单句的时候就要变成she了呢 这样有矛盾吗? My sister I have a sister Marry.She is 16 years old now.She is a beauty whose height is 163 cm.My 为什么Dose she have a sister用have,而不是has I have a sister的同义句 I have a sister who plays piano. 英语翻译My name is Sue.I'm ten.I'm from canada.I like Chinese foodvery much.I have a sister.She's thirteen.She likes music.
