These are my sister给my提问 These flowers used to be looked after by my grandpa改为主动语态 my grandma and my grandpa are my grandparent .这句话错在哪 these girls are my cousins. -------these girlsthese girls are my cousins. -------these girls ther are my grandpa and my grandma.前面问的是什么 they are my friend和these are my friend改错
